What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.?
o A. P= 35 in., A = 300 in.2
O B. P = 70 in., A = 300 in.2
o C. P = 300 in., A = 70 in.2
o D. P = 35 in., A = 200 in.2
9514 1404 393
Answer:
B. P = 70 in; A = 300 in²
Step-by-step explanation:
The perimeter is the sum of the side lengths. Opposite sides are the same length, so the perimeter is ...
P = 20 in + 15 in + 20 in + 15 in = 2(20 in +15 in) = 2(35 in)
P = 70 in.
Only answer choice B has the correct value. (Its area figure is also correct.)

Answer:
1. D
2. D
Step-by-step explanation:
First, find two points on the line that are EXACTLY on the dot. Count how many points the line goes down and to the side. Then put it into a slope which is rise/run or y/x
So since the two points I picked where 2 points down and 3 points to the side. Its 2/3. Also, the line is going down so its negative. Therefore, you make the slope negative. So, -2/3 is the answer.
2. In the equation, she did “1 - 17/ 1 - 20”
This is wrong because while the numerator is right, the original point was (20, 1) for the denominator. Therefore, she used y values where she should of use X-values as the equation should be

A sociologist wishes to conduct a poll to estimate the percentage of Americans who favor affirmative action program for women and minorities for admission to colleges and universities. What sample size should be obtained if she wishes the estimate to be within a margin of error of 0.04, with 95% confidence, if she uses a 2003 estimate of 0.55 obtained from a Gallup Youth Survey
Answer:
A sample of 595 should be obtained.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Estimate of 0.55
This means that [tex]\pi = 0.55[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What sample size should be obtained if she wishes the estimate to be within a margin of error of 0.04?
This is n for which M = 0.04. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.04 = 1.96\sqrt{\frac{0.55*0.45}{n}}[/tex]
[tex]0.04\sqrt{n} = 1.96\sqrt{0.55*0.45}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.55*0.45}}{0.04}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.55*0.45}}{0.04})^2[/tex]
[tex]n = 594.2[/tex]
Rounding up,
A sample of 595 should be obtained.

what sum of money amounts to rupees 8700 in 3 years at the rate of 24 % per annum
Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting [tex]A=8700,r=24,t=3[/tex], we get
[tex]8700=P\left(1+\dfrac{24}{100}\right)^{3}[/tex]
[tex]8700=P\left(1+0.24\right)^{3}[/tex]
[tex]8700=P\left(1.24\right)^{3}[/tex]
[tex]8700=1.906624P[/tex]
Divide both sides by 1.906624.
[tex]\dfrac{8700}{1.906624}=P[/tex]
[tex]4563.0391729=P[/tex]
[tex]P\approx 4563.04[/tex]
Therefore, the principal value is about 4563.04.

The expression x^2- x + 8.75 factors as (x + 2.5)(x - a) for some positive value "a". What is a?
step by step, please.
Answer:
3.5
Step-by-step explanation:
Write out quadratic
[tex] {x}^{2} - x + 8.75[/tex]
We are given that x+2.5 is a factor.
So our roots look like
[tex](x + 2.5)(x - a)[/tex]
Let apply the foil method to find some missing parts.
[tex]x \times x = {x}^{2} [/tex]
[tex]x \times - a = - ax[/tex]
[tex]2.5 \times x = 2.5[/tex]
[tex]2.5 \times - a = - 2.5a[/tex]
We know that the outer terms must multiply to 8.75. We also know that the middle terms must add up to -1.
[tex] - 2.5a = 8.75[/tex]
[tex] 2.5x - ax = -1[/tex]
The only number that satisfy this equation is
[tex] - 3.5[/tex]
Since it already negative, it is
[tex]3.5[/tex]

Based on the graph of the trigonometric functions f (θ) = 4sin θ + 3 and g (θ) = cos 2θ, at what value(s) on the interval [0, 2π) does f (θ) = g (θ)?
pi over 4 comma 3 times pi over 4 comma 5 times pi over 4 comma 7 times pi over 4
3 times pi over 2
pi over 2 comma 5 times pi over 2
5 times pi over 4 comma 7 times pi over 4
The value on the interval [0, 2π) where f(θ) = g(θ) is 3π/2.
To find the value(s) on the interval [0, 2π) where f(θ) = g(θ), we need to set the two functions equal to each other and solve for θ.
Setting f(θ) = g(θ), we have:
4sin(θ) + 3 = cos(2θ)
Now, we can solve this equation. Let's break it down step by step:
Rewrite cos(2θ) using the double-angle identity: cos(2θ) = 1 - 2sin^2(θ)
The equation becomes: 4sin(θ) + 3 = 1 - 2sin^2(θ)
Rearrange the equation:
2sin^2(θ) + 4sin(θ) + 2 = 0
Divide the entire equation by 2:
sin^2(θ) + 2sin(θ) + 1 = 0
Factorize the equation:
(sin(θ) + 1)^2 = 0
Solve for sin(θ):
sin(θ) = -1
The value of sin(θ) is -1 at θ = 3π/2.
As a result, 3π/2 is the value on the interval [0, 2π) where f(θ) = g(θ).
