If there are 240 students in the sixth-grade class then the number of votes that Naomi received is: 336 votes.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Bridgette and Naomi ran for sixth-grade class president.

In the election, every sixth-grade student voted for either Bridgette or Naomi.

Bridgette received 5 votes for every 7 votes Naomi received.

the first figure represents 5:7 ratio in the story.

Since Bridgette received 5 votes for every 7 votes Naomi received, Bridgette received 5/7 of the total votes and Naomi received 2/7 of the total votes.

We know that the total number of votes cast is equal to the total number of students in the class, which is 240.

Therefore, we can set up the equation:

⁵/₇(x) + ²/₇(x) = 240

Simplifying the equation, we get:

(5x + 2x)/7 = 240

7x/7 = 240

x = 240 × 7/5

x = 336

Therefore, If there are 240 students in the sixth-grade class then Naomi received 336 votes.

What is inequality?

In mathematics, an inequality is a mathematical statement that compares the values of two expressions or quantities using a relational symbol such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "!=" (not equal to).

A. s must be less than 35.

The inequality s < 35 means that the speed s must be less than 35 miles per hour, which is the speed limit on the neighborhood road. Therefore, statement A is true. Statement B is false because the least possible value of s is zero, not 35. Statement C is false because the greatest possible value of s is infinite, although there may be practical limits to how fast a vehicle can go on a neighborhood road. Statement D is false because s cannot be greater than 35 if the speed limit is 35 miles per hour.

Hence, the correct option would be s must be less than 35.

The given statement is true for all matrices A.

1) For any 2x2 matrices A and B, (AB)2 = A2B2 - False. A counter-example to this claim would be if A and B are non-invertible matrices, such as A = [1, 0; 0, 0] and B = [1, 0; 0, 1]. (AB)2 = [1, 0; 0, 0], but A2B2 = [1, 0; 0, 1].

2) For any 2x2 matrices A, B, and C, if AB = AC, then B = C - True. This statement is true, as long as A is an invertible matrix. This can be seen from the properties of matrix multiplication; if AB = AC, then B = A-1AC = C.

3) For any 2x2 matrix A, if A2 = A, then either A = 0 or A = I - False. A counter-example to this claim would be if A = [1, 0; 0, 0], then A2 = A = [1, 0; 0, 0], but A ≠ 0 and A ≠ I.

1) Counter-example:Let the matrices A and B be given by\[A=\begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix}, B=\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}\].Now,\[(AB)^2=\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}^2=\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}\].and\[A^2B^2=\begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix}^2\begin{pmatrix} 0 & 1 \\ 0 & 0 \end{pmatrix}^2=\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}=\begin{pmatrix} 0 & 0 \\ 0 & 0 \end{pmatrix}\]Hence\[(AB)^2\ne A^2B^2\]2) Let AB=AC.

In mathematics, a proportion is a statement that two ratios or fractions are equal. A proportion can be expressed as an equation of the form:

a/b = c/d

where a, b, c, and d are numbers, and b and d are not equal to zero. This equation can also be written in the form of a cross product:

ad = bc

This equation means that the product of the numerator of one fraction and the denominator of the other fraction is equal to the product of the denominator of the first fraction and the numerator of the second fraction.

a. If 20% of the students surveyed chose yellow and 48 students chose yellow, we can set up the following proportion to find the total number of students surveyed (let "x" be the total number of students):

20/100 = 48/x

Solving for x, we get:

x = 240

Therefore, 240 students were surveyed in all.

b. 25% of the students surveyed chose blue, so the number of students who chose blue is:

25/100 x 240 = 60

Therefore, 60 students chose blue.

c. We are given that 3% of the students surveyed chose purple, and 4% chose green. To find the number of students who chose purple or green, we can add the two percentages and find the corresponding portion of the total number of students:

3/100 + 4/100 = 7/100

So 7% of the students surveyed chose purple or green. The number of students who chose purple is:

3/100 x 240 = 7.2 (rounded to the nearest whole number, this is 7)

Similarly, the number of students who chose green is:

4/100 x 240 = 9.6 (rounded to the nearest whole number, this is 10)

We are also given that 3% of the students surveyed chose "other". Therefore, the number of students who chose "other" is:

3/100 x 240 = 7.2 (rounded to the nearest whole number, this is 7)

So 7 students chose "other".

Yes, dog will catch the frisbee. The coordinates of the point or points where they meet are (0,6) and (6,18). So, option(a) is correct answer for this question.

I have a training your dog to catch a frisbee. The path equation of frisbee is y= –x² + 8x + 6 --(1)

and the path equation of the dog is modeled by

y = 2x + 6 --(2)

We have to check dog catch the frisbee or not and also determine the coordinates. The dog will catch the frisbee, when both equations are intersect to each other. That is intersection point of equation (1) and (2) are the required coordinates. Now, we determine the intersection points between the equation (1) and (2).

Substituting the value of y from equation (2) to equation (1), y = 2x + 6 in y = - x² + 8x + 6

=> 2x + 6 = -x² + 8x + 6

Simplify, x² - 8x + 2x = 6-6

=> x² - 6x = 0

=> x( x - 6) = 0

either x = 0 or x -6 = 0

=> x = 0, x= 6

from equation (1), y = 2(0) + 6 = 6

when x = 6, y = 2(6) + 6 = 18

Hence, required coordinates are (0,6) and (6,18).

Seven people are in the pool who each have expected payouts of $8,600 for the year. One more person is added to the pool whose expected payout is $14,000 per year. How much is the average expected payout for each member of the group of eight? Expected Payout for each member of the group is $​

1. The population in 2005 was 5000

2. when t is -2, it indicates that 1250 the population before 2 years was 1250

3. For t  - -2 population was more than 1000

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal.

a. To find the population of the fish species in 2005, we need to plug in t = 0 into the equation:

p = 5,000 .2^t

p = 5,000 .2^0

p = 5,000

Therefore, the population of the fish species in 2005 was 5,000.

b. When t is -2, it means we are two years before 2005, the year when the fish population in the lake was first surveyed. In other words, we are trying to find the population of the fish species two years before 2005. To do this, we plug in t = -2 into the equation:

p = 5,000 .2^t

p = 5,000 .2^-2

p = 5,000 .25

p = 1,250

Therefore, the population of the fish species two years before 2005 was 1,250.

c. The fish population at t = -2 is more than 1,000. We know this because we calculated that the population was 1,250, which is greater than 1,000.

The median, Q₁, Q₃, lower fence and upper fence of the given data set are 82, 75, 83, 63 and 95.

What is Inter quartile range?

In a range of values, from lowest to highest, the IQR denotes the median 50% of values. Find the median (middle value) of the lower and higher half of the data first, then use that number to calculate the interquartile range (IQR). The first quartile (Q1) and third quartile (Q3) of these values (Q3). What separates Q3 from Q1 is known as the IQR.

Given data set : 72, 81, 82, 83, 83, 85, 100, 54, 75, 81, 83

Firstly, we will arrange the data into ascending order.

we get, 54, 72, 75, 81, 81, 82, 83, 83, 83, 85, 100.

Here, no. of terms is 11

So, Median = (n+1)/2 th = (11+1)/2 = 6th term

So, Median = 82.

Q₁ = (n+1)/4 th term = (11+1)4 th = 3rd term

                                                 = 75

Q₃ = 3(n+1)/4 th term = 9th term = 83

Inter-quartile range = Q₃ - Q₁

                                  = 83 - 75 = 8.

Now, Lower fence = Q₁ - 1.5*IQR

                              = 75 - 1.5× 8

                              = 75 - 12 = 63

       Upper fence = Q₃ + 1.5*IQR

                              = 83 + 1.5×8

                              = 83 + 12

The correct answer is option A, counter clockwise 90°, for the needle to lean on the outline section, the wheel must be turned counter clockwise 90°. Any other turn of the wheel will not result in the needle leaning on the outline section.

Counterclockwise is an adjective used to describe motion or rotation that is in the opposite direction of a clock's hands. For example, when a person swims in a pool, they may swim counterclockwise around the perimeter of the pool. This is the opposite direction of the way a clock's hands move. Counterclockwise rotation is also known as anti-clockwise rotation.

When an object is placed on a flat surface and the wheel is turned, it will rotate in the same direction as the motion of the wheel. If the needle is leaning on the outline section, the wheel must be turned counter clockwise 90°. This is because when the wheel is turned counter clockwise, the needle will be forced to move in the same direction and end up leaning on the outline section.

When the wheel is turned clockwise, the needle will move in the opposite direction and it will not end up leaning on the outline section. Therefore, a clockwise turn of 120° or 180° is not the correct answer. Similarly, turning the wheel counter clockwise by 180° is also not the correct answer. This is because the needle will end up pointing in the same direction it was pointing before the wheel was turned.

Given that diameter of a circle is 7 ft, its area to the nearest tenth is 38.5 square feet.

Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2 where r is the radius of the circle.

To find the radius, we can divide the diameter by 2: r = d/2 = 7/2 = 3.5 ft

Now we can plug this into the formula for the area:

A = πr^2

A = π(3.5)^2

A ≈ 38.48

Answer:

First, we need to calculate the total cost of Lisa's and Tracy's lunches before tax and tip.

Lisa's lunch = $6

Tracy's lunch = $7

Total before tax and tip = $6 + $7 = $13

Now we need to add the 5% sales tax:

$13 x 0.05 = $0.65

Total after tax = $13 + $0.65 = $13.65

Finally, we need to add the 15% tip:

$13.65 x 0.15 = $2.05

Total bill = $13.65 + $2.05 = $15.70

Therefore, the total bill, including tax and tip, is $15.70.

Answer:

Step-by-step explanation:

6 + 7 = 13

Now for the sales tax and tip, we need to add 15 and 5 together which is 20. So now we need to multiply 13 times the decimal equivalent of 20%. So, 0.20 x 13 = 2.6

2.6 + 13 = 15.6

The point on Π that is closest to A is (3,-2,0).

(a) The distance between the plane Π and the point A is 3. To find this, we need to find the equation of the plane Π. The equation of the plane is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane, which is perpendicular to the line that passes through points A and B. Since the normal vector of the plane is perpendicular to the line, the normal vector (A, B, C) is equal to the cross product of the two vectors of the line AB, given by:

A=(3,0,-2), B=(-1,1,0)

A x B = (A2B3-A3B2, A3B1-A1B3, A1B2-A2B1) = (-5,3,3)

Therefore, the equation of the plane Π is:

-5x + 3y + 3z + D = 0

To find D, we need to plug in the coordinates of the point (1,2,3). Therefore,

-5(1) + 3(2) + 3(3) + D = 0
-5 + 6 + 9 + D = 0
D = -20

Therefore, the equation of the plane Π is:

-5x + 3y + 3z - 20 = 0

To find the distance between the plane Π and the point A, we need to calculate the shortest distance between the plane and the point A. We can do this using the distance formula, given by:

d = |Ax + By + Cz + D|/sqrt(A^2 + B^2 + C^2)

Substituting the equation of the plane Π and the coordinates of point A into the distance formula, we get:

d = |-5(3) + 3(0) + 3(-2) - 20|/sqrt(-5^2 + 3^2 + 3^2)
d = |-15 - 20|/sqrt(34)
d = |-35|/sqrt(34)
d = 3

Therefore, the distance between the plane Π and the point A is 3.

(b) The point on Π that is closest to A is (3,-2,0). To find this, we need to solve the system of equations given by:

-5x + 3y + 3z - 20 = 0
x - 3 = 0
y - 0 = 0
z + 2 = 0

Solving this system of equations, we get x = 3, y = -2, and z = 0. Therefore, the point on Π that is closest to A is (3,-2,0).

The amount of money in account after 16 years will be $162,823.39. The solution has been obtained by using compound interest.

What is compound interest?

Compound interest considers the principal when determining the interest for the subsequent month, in contrast to simple interest, which does not. In algebra, compound interest is typically denoted by the letter C.I.

We are given the following information:

P = $72000

Rate (r) = 5.1% = 0.051

Time (t) = 16 years

Using the formula, we get

⇒V = P[tex]e^{rt}[/tex]

⇒V = (72000) e⁰°⁰⁵¹ˣ¹⁶

⇒V = (72000) e⁰°⁸¹⁶

⇒V = $162,823.39

Hence, the amount of money in account after 16 years will be $162,823.39.

Answer:

g(x) = f(x + 2) = 2^(x + 2) + 2

Step-by-step explanation:

To shift the function f(x) = 2^x + 2 two units to the left, we need to replace x with (x + 2) in the equation. This will shift the graph horizontally to the left by two units.

So, the new function g(x) that represents the shifted graph is:

g(x) = f(x + 2) = 2^(x + 2) + 2

By answering the above question, we may state that The circle's radius is  radius 8.5 feet as a result.

In more modern use, a circle's or sphere's length is equal to its radius, and it is one of the line segments connecting the object's centre and circumference. The phrase is derived from the Roman word circle, which also describes a waggon wheel's spokes. The radius of a circle is the separation of any points on its circumference from its centre. Often, it is denoted by "R" or "r". A line segment with one termination in the centre and one on the circle's perimeter is called a radius. Radius = circular diameter A circle's diameter is the portion that passes through its centre and has ends on the circle.

The formula for calculating a circle's circumference is:

C = 2πr

When r denotes the radius, C denotes the circumference, and denotes a mathematical constant roughly equal to 3.14159.

We are informed that the circle's diameter is 17 feet. We may solve for r by setting this equal to the circumference formula:

17π = 2πr

By multiplying both sides by 2, we obtain:

r = 17π / (2π)

The units are cancelled, leaving:

r = 17 / 2

Examining this expression results in:

r = 8.5 ft

The circle's radius is 8.5 feet as a result.

The solution of the system of equations by substitution method is 3x + 4(2x - 7) = 16, The correct option is D.

To solve the system of equations {y=2x-7, 3x+4y=16} using substitution, we can solve the first equation for y in terms of x (or x in terms of y) and substitute this expression into the second equation.

Solving the first equation y=2x-7 for y, we get:

y = 2x - 7

We can substitute this expression for y into the second equation 3x+4y=16, replacing y with 2x-7, to get:

3x + 4(2x - 7) = 16

Therefore, the expression after substituting the value of y is 3x + 4(2x - 7) = 16.
