Answer:
4.5 ×1000 =4500m
Step-by-step explanation:
450/1000=0.45km
Answer: 10 : 1
Step-by-step explanation: Now first let’s convert this to the same units, for instance, the SI unit for length meters. 4.5 x 1000 = 4500m. Then put the ratio 4500m : 450m. You can divide 4500 by 450 as it is divisible so you get 10 as the answer.
Even if you have converted them to kilometers before, nevermind, still 4.5 divide by 0.45 is 10 and there the answer is 10 : 1 or shortly the ratio is just 10.
Find local maximum or minimum of the function: f(x)= (x + 1)^2(x - 3) Local maximum point= ( , ) Local maximum value= Local minimum point = ( , ) Local minimum value=
Answer: Local Max = (-1, 0)
Local Min = (1, -8)
Step-by-step explanation:
f(x) = (x + 1)² (x - 3)
Step 1: Find the zeros
(x + 1)² = 0 --> x = -1 (multiplicity of 2)
(x - 3) = 0 --> x = 3
Step 2: Find the Vertices
x = -1 --> (multiplicity is even which means this is a vertex)
The midpoint between x = -1 and x = 3 is x = 1
Step 3: Find the Local Max and Local Min
Use the x-value above to find the y-values
f(-1) = 0 because it is a zero
f(1) = (1 + 1)² (1 - 3)
= 2²(-2)
= 4(-2)
= -8
Conclusion:
(-1, 0) is the Local Max bigger y-value
(1, -8) is the Local Min smaller y-value
Answer:
f ( x ) = ( x – 3) 2 – 4; the minimum value is –4
Step-by-step explanation:
Given the function f ( x ) = x 2 – 6 x + 5, write an equivalent form of the function that reveals the minimum or maximum value of the function and state the minimum or maximum value.
f ( x ) = ( x – 3) 2 – 4; the minimum value is –4

Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish to compare the means of two populations using paired observations. Suppose that d=3.125, sd=2.911, and n=8, and that you wish to test the hypothesis below at the 10% level of significance. What decision rule would you use? H0: μd=0 against H1: μd>0
Answer:
If the value of our test statistics is less than the critical value of t at 7 degrees of freedom at a 10% level of significance for the right-tailed test (which is 1.415), then we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.
If the value of our test statistics is more than the critical value of t at 7 degrees of freedom at a 10% level of significance for the right-tailed test (which is 1.415), then we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.
Step-by-step explanation:
We are given that the means of two populations using paired observations. Suppose that [tex]\bar D[/tex] = 3.125, [tex]s_D[/tex] = 2.911, and n = 8, and that you wish to test the hypothesis below at the 10% level of significance.
Let D = difference between the two paired observations.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu_D[/tex] = 0
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu_D[/tex] > 0
The test statistics that would be used here is Paired t-test for dependent samples;
T.S. = [tex]\frac{\bar D-\mu_D}{\frac{s_d}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar D[/tex] = 3.125, [tex]s_D[/tex] = 2.911, and n = 8
The decision rule for rejecting the null hypothesis in the given hypothesis test would be;
If the value of our test statistics is less than the critical value of t at 7 degrees of freedom at a 10% level of significance for the right-tailed test (which is 1.415), then we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.If the value of our test statistics is more than the critical value of t at 7 degrees of freedom at a 10% level of significance for the right-tailed test (which is 1.415), then we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.What is x? The degree of the angle of x
Answer:
x = 60°
Step-by-step explanation:
All the angles in a triangle add up to 180°. So, you have this equation.
87° + 33° + x = 180°
120° + x = 180°
x = 60°
The measure of angle x is 60°.

$43,870
$635
$655
$41,999
$39,784
Answer:
$41,999
Step-by-step explanation:
Annual income = 45000
monthly income = $45000/12 months = $3750
mandatory expense at 38% rule = $3750 x 0.38 = 1425
other debt = 790
tax and insurance = 340
= 1425 - 790 - 340
= 295
balance left = 295
mortgage payment = (295/8.78) x 1000
= $33,599
purchase price = monthly payment/ 1- % of down payment
= $33599/1 - 0.20
= 33599/0.80
= $41,999

Test the claim that the proportion of men who own cats is smaller than 70% at the 0.05 significance level. The null and alternative hypothesis would be:
Answer:
the null hypothesis would be: p = 70%/0.7
The alternative hypothesis would be: p < 0.7
Step-by-step explanation:
The null hypothesis is most of the time always the default statement while the alternative hypothesis is tested against the null and is its opposite.
In this case study the null hypothesis would be: the proportion of men who own cats is 70%: p = 0.7
The alternative hypothesis would be: the proportion of men who own cats is smaller than 70% : p < 0.7
I made a square frame for my favorite bird picture from four wooden pieces. Each piece is a rectangle with a perimeter of 24 inches. What is the area and perimeter of the picture and frame, together?
Answer:
Perimeter of the picture and frame = 38.4inches
Area of the picture and frame = 92.16inches²
Step-by-step explanation:
A square frame is made up of 4 different pieces. The shape of each piece = Rectangle
The perimeter of the rectangle = 24
Perimeter of the rectangle = 24 inches
The perimeter of a rectangle = 2L + 2W
The Width of a Rectangle is always on her than the length hence.
24 = 2L + 2W
24 = 2( L + W)
24/2 = L + W
12 = L + W
Because the width is always longer than the length
W > L
Width of wooden frame = 4 × Length
Therefore;
4 × L = W
Which gives
L + W = 12 inches
4 × L + L = 12 inches
L×(4 + 1)
= 5L = 12 inches
L = 12/5 = 2.4 inches
W = 4 × L = 4 × 12/5
W = 48/5 = 9.6 inches
Side length of wooden frame, L =9.6
The perimeter of the picture frame = 4 × L= 4 × 9.6= 38.4 inches
The area of the picture frame = L²
= L × L
= 9.6 × 9.6 = 92.16inches².

High Fructose Corn Syrup (HFCS) is a sweetener in food products that is linked to obesity and type II diabetes. The mean annual consumption in the United States in 2008 of HFCS was 60 lbs with a standard deviation of 20 lbs. Assume the population follows a Normal Distribution.
a. Find the probability a randomly selected American consumes more than 50 lbs of HFCS per year.
b. Find the probability a randomly selected American consumes between 30 and 90 lbs of HFCS per year.
c. Find the 80th percentile of annual consumption of HFCS.
d. In a sample of 40 Americans how many would you expect to consume more than 50 pounds of HFCS per year.
e. Between what two numbers would you expect to contain 95% of Americans HFCS annual consumption?
f. Find the quartile and Interquartile range for this population.
g. A teenager who loves soda consumes 105 lbs of HFCS per year. Is this result unusual?
Answer:
Explained below.
Step-by-step explanation:
X = annual consumption in the United States in 2008 of HFCS
[tex]X\sim N(60, 20^{2})[/tex]
(a)
Find the probability a randomly selected American consumes more than 50 lbs of HFCS per year.
[tex]P(X>50)=P(\frac{X-\mu}{\sigma}>\frac{50-60}{20})=P(Z>-0.50)=P(Z<0.50)=0.6915[/tex]
P (X > 50) = 0.6915.
(b)
Find the probability a randomly selected American consumes between 30 and 90 lbs of HFCS per year.
[tex]P(30<X<90)=P(\frac{30-60}{20}<\frac{X-\mu}{\sigma}<\frac{90-60}{20})\\\\=P(-1.5<Z<1.5)\\\\=0.93319-0.06681\\\\=0.86638\\\\\approx 0.8664[/tex]
P (30 < X < 90) = 0.8664.
(c)
Find the 80th percentile of annual consumption of HFCS.
P (X < x) = 0.80
⇒ P (Z < z) = 0.80
⇒ z = 0.84
[tex]z=\frac{x-\mu}{\sigma}\\\\0.84=\frac{x-60}{20}\\\\x=60+(20\times 0.84}\\\\x=76.8[/tex]
80th percentile = 76.8.
(d)
In a sample of 40 Americans how many would you expect to consume more than 50 pounds of HFCS per year.
P (X > 50) = 0.6915
Number of American who consume more than 50 lbs = 40 × 0.6915
= 27.66
≈ 28
Expected number = 28.
(e)
Between what two numbers would you expect to contain 95% of Americans HFCS annual consumption?
According to the Empirical rule, 95% of the normally distributed data lies within 2 standard deviations of mean.
[tex]P(\mu-2\sigma<X<\mu+2\sigma)=0.95\\\\P(60-2\cdot20<X<60+2\cdot20)=0.95\\\\P(20<X<100)=0.95[/tex]
Range = 20 < X < 100.
(f)
Find the quartile and Interquartile range for this population.
1st quartile: Q₁
P (X < Q₁) = 0.25
⇒ P (Z < z) = 0.25
⇒ z = -0.67
[tex]z=\frac{Q_{1}-\mu}{\sigma}\\\\-0.67=\frac{Q_{1}-60}{20}\\\\Q_{1}=60-(20\times 0.67)\\\\Q_{1}=46.6[/tex]
3rd quartile: Q₃
P (X < Q₃) = 0.75
⇒ P (Z < z) = 0.75
⇒ z = 0.67
[tex]z=\frac{Q_{3}-\mu}{\sigma}\\\\0.67=\frac{Q_{3}-60}{20}\\\\Q_{3}=60+(20\times 0.67)\\\\Q_{3}=73.4[/tex]
Inter quartile range:
[tex]IQR=Q_{3}-Q_{1}=73.4-46.6=26.8[/tex]
(g)
Compute the z-score for x = 105 lbs as follows:
[tex]z=\frac{Q_{3}-\mu}{\sigma}\\\\z=\frac{105-60}{20}\\\\z=2.25[/tex]
Z-scores greater than +2.00 or less than -2.00 are considered as unusual.
Thus, the result unusual.

Find the maximum and minimum values
Answer:
2 and 10 are the in and max
Answer:
Min = 2
Max = 10
Step-by-step explanation:
C = 2(x+y)
x ≥1
y ≥0
y ≤5 -x
The smallest y can be is zero
The smallest x can be is 1
The minimum is
C = 2 ( 0+1) = 2 ( 1) = 2
Looking for the max
y ≤5 -x
Add x to each side
x+y ≤5
The max is 5 for x+y
Substituting that into the equation for C
C = 2(5)
C = 10
Min = 2
Max = 10

Find the average rate of change of the function from x=1 to x=2. f(x)=−6/x^2
Answer:
4.5.
Step-by-step explanation:
f(x) = −6 / x^2
f(1) = -6 / (1)^2 = -6 / 1 = -6.
f(2) = -6 / (2)^2 = -6 / 4 = -3 / 2 = -1.5.
Now, you have two sets of coordinates: (1, -6), and (2, -1.5).
You need to find the slope, which is the average rate of change.
(-1.5 - (-6)) / (2 - 1) = (-1.5 + 6) / 1 = -1.5 + 6 = 4.5
Hope this helps!
The average rate of change of the function from x=1 to x=2 is 4.5
The average rate of change of a function is given by:
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Hence, the average rate of change of the function from x=1 to x=2. f(x)=−6/x² is:
f(2) = -6/2² = -1.5
f(1) = -6/1² = -6
[tex]Average\ rate\ of\ change=\frac{f(2)-f(1)}{2-1}=\frac{-1.5-(-6)}{2-1}=4.5[/tex]
Hence the average rate of change of the function from x=1 to x=2 is 4.5

doreen schmidt Is a chemist. She needs to prepare 36 ounces of a 16% hydrochloric acid solution. Find the amount of 18% solution and the amount of 9% solution she should mix to get this solution
Please help.
Answer:
Mixing two concentrations for known amount of mixture
Step-by-step explanation:
Let x = amount (ounces) of 18% solution
then
36-x = amount (ounces) of 9% solution
0.18x + 0.09(36-x) = .16(36)
0.18x + 3.24-.09x = 5.76
0.09x + 3.24 = 5.76
0.09x = 2.52
x = 28 ounces of 18% solution
amount of 9% solution:
36-x = 36-18 = 18 ounces
"prepare 36 ounces", means mass or weight.
Let u = ounces of 16%
Let v = ounces of 18%
(16u + 18v)/36=9
and u + v = 36
based on the above findings....

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of 0°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0°C (denoted by negative numbers) and some give readings above 0°C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places.
Answer:
the temperature reading that separates the bottom 4% from the others is -1.75°
Step-by-step explanation:
The summary of the given statistics data set are:
Mean [tex]\mu[/tex] : 0
Standard deviation [tex]\sigma[/tex] = 1
Probability of the thermometer readings = 4% = 0.04
The objective is to determine the temperature reading that separates the bottom 4% from the others
From the standard normal table,
Z score for the Probability P(Z < z) = 0.04
P(Z < -1.75) = 0.04
z = -1.75
Now, the z- score formula can be expressed as :
[tex]z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]-1.75 = \dfrac{X-0}{1}[/tex]
-1.75 × 1 = X - 0
X = -1.75 × 1 - 0
X = -1.75
Therefore, the temperature reading that separates the bottom 4% from the others is -1.75°

Graph the equation y=4x+1 by plotting points.
Look at the attached image (credit to Desmos graphing calculator)
To graph the equation y=4x+1, we just find two points that exist, plot them, and draw a straight line that goes through them.
Let's try x=0:
[tex]y=4(0)+1=1[/tex]
One point on the line is (0,1)
Let's try x=1:
[tex]y=4(1)+1=5[/tex]
Another point is (1,5).
Now, plot these two points and draw a line through them.
The graph of the equation represents that straight line connecting the points (0, 1), (1, 5), and (-1, -3) on a coordinate plane.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
To plot the graph of the equation y=4x+1 by plotting points, we need to choose some values of x and then calculate the corresponding values of y using the equation.
Let's choose some values of x and calculate the corresponding values of y:
When x = 0, y = 4(0) + 1 = 1, so one point on the graph is (0, 1).
When x = 1, y = 4(1) + 1 = 5, so another point on the graph is (1, 5).
When x = -1, y = 4(-1) + 1 = -3, so another point on the graph is (-1, -3).
We can continue this process to find more points, or we can use these three points to draw a straight line through them.
Thus, the graph of the equation represents that straight line connecting the points (0, 1), (1, 5), and (-1, -3) on a coordinate plane.

cos(0)=√2/2, and 3π/2<0<2π, evaluate sin(0) and tan(0). Sin(0)?
Answer:
Option (2)
Step-by-step explanation:
In this question we have to find the values of Sinθ and tanθ where [tex]\frac{3\pi}{2}<x<2\pi[/tex].
Cosθ = [tex]\frac{\sqrt{2}}{2}[/tex] ⇒ θ = [tex]\frac{7\pi }{4}[/tex]
[Since [tex]\text{Cos}\frac{7\pi }{4}=\text{Cos}(2\pi-\frac{\pi}{4})[/tex]
[tex]=\text{Cos}\frac{\pi }{4}[/tex]
[tex]=\frac{\sqrt{2} }{2}[/tex] ]
Since Cosine of any angle between [tex]\frac{3\pi}{2}[/tex] and 2π is positive and Sine is negative in nature,
[tex]\text{Sin}\frac{7\pi }{4}[/tex] = [tex]-\frac{\sqrt{2}}{2}[/tex]
Since, tanθ = [tex]\frac{\text{Sin}\theta}{\text{Cos}\theta}[/tex]
tanθ = [tex]\frac{\frac{-\sqrt{2} }{2} }{\frac{\sqrt{2} }{2} }[/tex]
= [tex]-\frac{\sqrt{2}}{2}\times \frac{2}{\sqrt{2}}[/tex]

Jill put 53 buttons in a box. Marci put 17 buttons in an other box. Jarrod says Marci has 33 fewer buttons than Jill. He thinks 53-20 is easier to subtract than 53-17. He subtracts 53-20 and gets 33. Do you agree or not agree with Jarid's thinking?
Answer:I do not agree
Step-by-step explanation:he needs to take away 17 if he takes away 20 not 17 he needs to return 20-17=3 so in easier words you do 53-20+3=36
The graph of a quadratic function with vertex (0, 4) is shown in the figure below.
Find the domain and the range.
Write your answers as inequalities, using X or y as appropriate.
Or, you may instead click on "Empty set" or "All reals" as the answer.
Answer:
See below
Step-by-step explanation:
The domain of the quadratic equation is going to be [tex]\mathbb{R}[/tex] (all reals), since you can set x to be any real number and get a real value of y.
I can't see the graph, but the range of the quadratic is going to be y ≥ 4 (if the graph opens upwards) or y ≤ 4 (if the graph opens downwards).
A mechanic's tool set is on sale for $204 after a markdown of 40% off the regular price. Find the regular price.
Answer:
$340
Step-by-step explanation:
From the information given we know that $204 is the price after a 40% discount is applied which means that this value represents 60% of the regular price and you can find the answer using the rule of three:
204 → 60%
x ← 100%
x=(204*100)/60=340
According to this, the answer is that the regular price of the product is $340.
340*0.4= 136
340-136=204
