Answer:
$211 if rounding to nearest whole number (this may be what looking for)
$211.20 if rounding to nearest tenth
Step-by-step explanation:
The answer depends on what precision of rounding is done so i am providing 2 answers
Rounding to the nearest whole number:
14,49 rounded = 14
68.64 rounded = 69
128.05 rounded = 128
$14.49 + $68.64 + $128.05 = 14 + 69 + 128
= $211
Rounding to the tenths:
14,49 rounded = 14.5
68.64 rounded = 68.6
128.05 rounded = 128.1
$14.49 + $68.64 + $128.05= 14.5 + 68.6 + 128.1 = $211.20

The product of the two given binomials can be expressed as the trinomial 2561104x³ + 684636x² + 87719x + 736, which is in its simplest form.
In this case, we will multiply the first two binomials (12x+1)(21x+1) and then multiply the second two binomials (65x+32)(56x+23). We will then multiply the two resulting expressions to get the final trinomial.
To multiply (12x+1)(21x+1), we can use the distributive property of multiplication, which states that a(b+c) = ab + ac. Therefore, we have:
(12x+1)(21x+1) = 12x(21x) + 12x(1) + 1(21x) + 1(1) = 252x² + 12x + 21x + 1 = 252x² + 33x + 1
Similarly, to multiply (65x+32)(56x+23), we have:
(65x+32)(56x+23) = 65x(56x) + 65x(23) + 32(56x) + 32(23) = 3640x² + 1495x + 1792x + 736 = 3640x² + 3287x + 736
Now, to find the product of the two expressions, we can multiply them using the distributive property again:
(252x² + 33x + 1)(3640x² + 3287x + 736) = 252x²(3640x²) + 252x²(3287x) + 252x²(736)
• 33x(3640x²) + 33x(3287x) + 33x(736)
• 1(3640x²) + 1(3287x) + 1(736)
Simplifying this expression by combining like terms, we get:
= 917280x⁴ + 1573824x³ + 684636x² + 87719x + 736
This final expression has four terms, but it can be simplified further to a trinomial by combining the first two terms using the associative property of addition. We have:
917280x⁴ + 1573824x³ + 684636x² + 87719x + 736 = (917280x⁴ + 1573824x³) + (684636x² + 87719x + 736) = 2561104x³ + 684636x² + 87719x + 736

Answer:
35° and 55°
Step-by-step explanation:
(x - 20) and x form a right angle (90° ) and are complementary
complementary angles sum to 90° , then
x - 20 + x = 90
2x - 20 = 90 ( add 20 to both sides )
2x = 110 ( divide both sides by 2 )
x = 55
then the 2 angles are
x = 55°
x - 20 = 55 - 20 = 35°
A ladder, 3.8m long, leans against a building. If the angle between the ground and the ladder is 51°, how far from the wall is the bottom of the ladder? Round the answer to the nearest tenth.
We can use trigonometry to solve this problem.
Let's call the distance we are looking for "x". We can use the sine function, which relates the opposite side of a right triangle to its hypotenuse:
sin(51°) = opposite/hypotenuse
We know that the hypotenuse is the length of the ladder, which is 3.8m. We can solve for the opposite side (x) by rearranging the equation:
x = sin(51°) * 3.8m
x ≈ 2.98m
So the bottom of the ladder is about 2.98 meters away from the wall. Rounded to the nearest tenth, the answer is 3.0 meters.
Suppose that the amount of time that students spend studying in the library in one sitting is normally distributed with mean 46 minutes and standard deviation 19 minutes.

What is the least total time that a group can study and still receive a sticker? minutes License Points possible: 6 This is attempt 1 of 1. Submit ions
The distribution is X ~ N(46, 19), the probability that a randomly selected student's time will be between 42 and 44 minutes is 0.04147. the probability that the average time studying for the 50 students is between 42 and 44 minutes is 0.1601.
What is the distribution?a. X ~ N(46, 19)
b. e is not defined in the problem, so it does not have a distribution.
c. z ~ N(0, 1) (standard normal distribution)
d. To find the probability that one randomly selected student's time will be between 42 and 44 minutes, we first standardize the values:
z = (44 - 46) / 19 = -0.1053
z = (42 - 46) / 19 = -0.2105
Using a standard normal table or calculator, we can find the area under the standard normal curve between these two z-scores:
P(-0.2105 < z < -0.1053) = 0.04147
Therefore, the probability that a randomly selected student's time will be between 42 and 44 minutes is 0.04147.
e. To find the probability that the average time studying is between 42 and 44 minutes, we need to use the central limit theorem. Since we have a large enough sample size (n = 50) and the population standard deviation is known, we can use the following formula to standardize the sample mean:
z = (x - μ) / (σ / √n)
Substituting the given values:
z = (44 - 46) / (19 / √50) = -0.7443
z = (42 - 46) / (19 / √50) = -1.4886
Using a standard normal table or calculator, we can find the area under the standard normal curve between these two z-scores:
P(-1.4886 < z < -0.7443) = 0.1601
Therefore, the probability that the average time studying for the 50 students is between 42 and 44 minutes is 0.1601.
f. The total study time for the 50 students follows a normal distribution with mean 5046 = 2300 minutes and standard deviation √5019 ≈ 39.70 minutes. To find the probability that the total study time is more than 2200 minutes, we standardize the value:
z = (2200 - 2300) / 39.70 = -2.5189
Using a standard normal table or calculator, we can find the area under the standard normal curve to the right of this z-score:
P(z > -2.5189) = 0.99411
Therefore, the probability that the randomly selected 50 students will have a total study time more than 2200 minutes is 0.99411.
g. The assumption of normality is necessary for parts e) and f) because we are using the normal distribution and the central limit theorem to approximate the probabilities. Without the normal assumption, we would need to use different methods for probability calculations.
h. We need to find the least total time that corresponds to the top 15% of the distribution. Using a standard normal table or calculator, we can find the z-score that corresponds to the 85th percentile:
z = 1.0364
We can then use the formula for the total study time:
x = μ + z(σ / √n)
Substituting the given values:
x = 4650 + 1.0364(19*√50) ≈ 4652.78
Therefore, the least total time that a group can study and still receive a sticker is approximately 4652.78 minutes.

Suppose that you are headed toward a plateau 40 m high. If the angle of elevation to the top of the plateau is 20°, how far are you from the base of the plateau?
When the angle of elevation to the plateau's top is 20°, we are therefore 34.22 metres distant from the plateau's foot.
what is angle?An angle, also known as the vertex of the angle, is the shared endpoint where two lines, line segments, or rays come together in geometry. Angles are commonly expressed as degrees or radians. A radian is the angle that the centre of a circle is subtended by an arc that is the same length as the circle's radius, while a degree is equal to 1/360th of a complete revolution. The relationships between lines and shapes are described using angles, which are essential to many mathematical ideas and applications in physics, engineering, and other disciplines.
given
Trigonometry can be used to resolve this issue. Let's designate the distance "x" from the plateau's base to where we are right now.
We must first determine the height we are at right now. Since we are aware of the slope angle, we can accomplish this using the tangent function:
tan(20°) Means adjacent/opposite
h is the height we are presently at, so tan(20°) = h/x.
To find h, we can change this equation as follows:
h Equals x * tan(20°)
x² + h² = 40^2
If you replace h = x * tan(20°):
x² + (x*tan(20°))
x² = 40²
Simplifying:
x² + 0.364x²= 1600
1.364x² = 1600
x² = 1171.61
x ≈ 34.22
When the angle of elevation to the plateau's top is 20°, we are therefore 34.22 metres distant from the plateau's foot.

use the body temperatures, in degrees in fahrenheit, listed in the accompanying table. the range of the data is 3.5 degrees F. use the range rule of thumb to estimate the value of the standard deviation. compare the result to the actual standard deviation of the data rounded to two decimal places, 0.72 degrees F, assuming the goal is to approximate the standard deviation within 0.2 degrees F.
The estimated value of the standard deviation using the range rule of thumb is 0.875 degrees F
The range rule of thumb is used to estimate the standard deviation of a data set using the range of the data. In this case, the range of the data is 3.5 degrees F. Using the range rule of thumb, the standard deviation of the data can be estimated by taking the range (3.5) and dividing it by 4, which gives us an estimated standard deviation of 0.875 degrees F.
This estimated value is within 0.2 degrees F of the actual standard deviation of the data (0.72 degrees F).
To compare this result to the actual standard deviation of the data, we subtract the estimated value from the actual value and take the absolute value of the result. This gives us the difference between the two values:
|0.72 - 0.875| = 0.155
Since the difference between the estimated and actual standard deviations is less than 0.2 degrees F, we can say that the range rule of thumb provides a reasonable approximation of the standard deviation for this data set.
In conclusion, the estimated value of the standard deviation using the range rule of thumb is 0.875 degrees F, and this value is within 0.2 degrees F of the actual standard deviation of 0.72 degrees F.

A group of educational researchers had previously conducted research and determined that several factors were positively related with test scores including the number of hours of sleep on the night before the test, the number of hours spent studying the week before the test, and the student's IQ. Now the researchers wanted to determine if when compared, which variable or combination of variables better predicts test scores
Can you review and help support my findings?
Based on the information presented: What is the null and alternative hypothesis? Write these out symbolically too.
What is the independent variable in the scenario? What type of data is being collected for the independent variable?
The independent variables are the number of hours slept on the night of the test and the number of hours spend studying the week before the test. The data is quantitative and discrete.
c. What is the dependent variable in the scenario? What type of data is being collected for the dependent variable
The dependent variable is the IQ or test score and the data is ratio.
What statistical test would be used to test the hypothesis?
A f test is the best fit for this review.
e. Support for above answers: Explain how the hypothesis and level of measurement both helped determine the type of statistical test that would be most appropriate for this study. Provide rationale for test selection using source information and discussion.
The hypothesis of this research is that there is a positive correlation between the independent variables (hours slept on the night of the test, hours spent studying the week before the test, and student's IQ) and the dependent variable (test scores). As such, the null hypothesis states that there is no relationship between the independent variables and the dependent variable, while the alternative hypothesis states that there is a relationship between the independent variables and the dependent variable. Symbolically, this can be written as:
H0: There is no relationship between the independent variables and the dependent variable
H1: There is a relationship between the independent variables and the dependent variable
Given the hypothesis, the independent variable (number of hours of sleep, number of hours spent studying, and IQ) are quantitative and discrete, and the dependent variable (test scores) is ratio, an f test is the most appropriate statistical test to use. An f test will allow us to compare the independent variables to see if there is a statistically significant difference between the independent variables and the dependent variable. By using an f test, we can determine if the independent variables are actually associated with the dependent variable and how strong that association is.

The legs of an isosceles trapezoid are 10. The bases are 9 and 21. Find the area of the trapezoid and the lengths of the diagonals.
The area of the trapezoid is 75 square units, and the lengths of the diagonals are 13 and 17 units.
Describe Isosceles Trapezoid?An isosceles trapezoid is a type of trapezoid with two parallel sides that are equal in length, and two non-parallel sides that are also equal in length. The two legs meet at an angle at the top of the trapezoid, and the bases are parallel to each other.
To find the area of the trapezoid, we use the formula:
Area = (b1 + b2) * h / 2
where b1 and b2 are the lengths of the bases, and h is the height.
In this case, b1 = 9, b2 = 21, and h is the distance between the bases. Since the trapezoid is isosceles, the height is also the length of the two diagonals minus the sum of the two bases, divided by 2:
h = (d1 + d2 - b1 - b2) / 2
we will use the Pythagorean theorem:
d1² = h² + (b2 - b1/2)²
d2² = h² + (b2 + b1/2)²
Plugging in the values we get:
h = (d1 + d2 - 9 - 21) / 2
h = (d1 + d2 - 30) / 2
d1² = h² + (21 - 9/2)²
d2² = h² + (21 + 9/2)²
Simplifying, we get:
h = (d1 + d2 - 30) / 2
d1² = h² + 225/4
d2² = h² + 529/4
Substituting the first equation into the other two, we get a system of two equations in two variables:
d1² = ((d1 + d2 - 30) / 2)² + 225/4
d2² = ((d1 + d2 - 30) / 2)² + 529/4
Simplifying and solving for d1 and d2, we get:
d1 = 13
d2 = 17
To find the area, we plug in the values of the bases and the height:
h = (d1 + d2 - 30) / 2 = (13 + 17 - 30) / 2 = 5
Area = (b1 + b2) * h / 2 = (9 + 21) * 5 / 2 = 75
Therefore, the area of the trapezoid is 75 square units, and the lengths of the diagonals are 13 and 17 units.

A student needs 8 more classes to complete her degree. If she has met 5 pre-requisites for all the courses, how many ways can she take 4 classes next semester?
There is no way for the student to take 4 classes next semester, given that she needs 8 more classes to complete her degree and has already met 5 pre-requisites.
Since the student needs to take 8 more classes to complete her degree and has already taken 5 pre-requisites, she has 8 - 5 = 3 classes that she can choose from for next semester.
To calculate the number of ways she can take 4 classes next semester, we can use the combination formula:
nCr = n / (r × (n-r))
where n is the number of classes she can choose from (which is 3), and r is the number of classes she will take next semester (which is 4).
Plugging in the values, we get:
3C4 = 3 / (4 × (3-4)) = 0
Since we cannot choose 4 classes from a set of 3 classes, the answer is 0.
Therefore, there is no way for the student to take 4 classes next semester, given that she needs 8 more classes to complete her degree and has already met 5 pre-requisites.

Graph the solution to the following system of inequalities.
v55x - 2
y>-28+5
Answer: See attached.
Step-by-step explanation:
Since the first equation uses a ≤ symbol, we know we will use a solid line. This is because it is less than and equal to. Then, we will graph it as a regular slope-intercept line.
This line has a slope of 5 and a y-intercept of -2. This means we will start at (0, -2) and move five units up for every unit right, or five units down for every unit left.
For the next equation, it uses a > symbol so we will use a dashed line. This is because it is not equal to, only greater than. Same as the previous. We will graph it as a slope-intercept line, but using a dashed line instead of a solid line.
This line has a slope of -2 and a y-intercept of positive 5. This means we will start at (0, 5) and move two units down for every unit right, or two units up for every unit left.
Colin is making soap for gifts. The table shows the cost of the scented oils needed to make each kind of soap. He needs 1. 5 ounces of Scented oil to make a batch of soap. If he wants to make 2 batches of lavender soap and 2 batches of vanilla soap, how much money will he need for the oils? Almond oil - $1. 23 per ounce
Lavender -$1. 54
Vanilla -$1. 65
Melon -$1. 12
If Colin wants to make 2 batches of Lavender soap and 2 batches of Vanilla soap, then he will need $9.57 for the oils
Here, Colin needs 1.5 ounces of Scented oil to make a batch of soap.
He wants to make 2 batches of Lavender soap and 2 batches of vanilla soap.
So, the amount of scented oil for 2 batches would be:
1.5 × 2 = 3 ounces
The cost of an ounce of Lavender oil is $1.54
So, using unitary method the cost of oil for the 2 batches of Lavender soap would be:
C₁ = 3 × 1.54
C₁ = 4.62 dollars
The cost of an ounce of Vanilla oil is $1.65
So, using unitary method the cost of oil for the 2 batches of Vanilla soap would be:
C₁ = 3 × 1.65
C₁ = 4.95 dollars
Thus, the total cost would be,
C = C + C
C = 4.62 + 4.95
C = 9.57 dollars

Determine the LCM of the given polynomials: Leave your answer in factored form. \[ x^{2}+10 x+25 \text { and } x^{2}+11 x+30 \]
The common factors are \[(x+5)\], so the LCM is (x+5)²(x+6) of the given polynomials. The Least Common Multiple (LCM) of the two given polynomials can be found by factoring them and then finding the common factors:
\[ x²+10 x+25 = (x+5)(x+5) \]
\[ x²+11 x+30 = (x+5)(x+6) \]
To determine the LCM of the given polynomials, we need to factor each polynomial and then multiply the factors together, taking the highest power of each factor.
First, let's factor each polynomial:
\[ x²+10 x+25 = (x+5)(x+5) \]
\[ x²+11 x+30 = (x+5)(x+6) \]
Now, let's find the LCM by multiplying the highest power of each factor together:
LCM = (x+5)(x+5)(x+6) = (x+5)²(x+6)
So, the LCM of the given polynomials is (x+5)²(x+6) in factored form.
