Answer:
B) ∠SBY = 117°
Step-by-step explanation:
interior angles in a pentagon = (5x180) - 360 = 540°
each angle = 540/5 = 108°
interior angles in a octagon = (8x180) - 360 = 1080°
each angle = 1080/8 = 135°
∠SBY = 360 - 108 - 135 = 117°

A researcher wants to estimate the percentage of all adults that have used the Internet to seek pre-purchase information in the past 30 days, with an allowable sampling error (E) of 0.03 and a confidence level of 99.74%. Of secondary data indicated that 25% of all adults had used the Internet for such a purpose, what is the sample size
Answers
Answer:
The sample size is 1875.
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]
Sampling error of 0.03.
This means that [tex]M = 0.03[/tex]
99.74% confidence level
So [tex]\alpha = 0.0026[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.0026}{2} = 0.9987[/tex], so [tex]Z = 3[/tex].
25% of all adults had used the Internet for such a purpose
This means that [tex]\pi = 0.25[/tex]
What is the sample size
The sample size is n. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 3\sqrt{\frac{0.25*0.75}{n}}[/tex]
[tex]0.03\sqrt{n} = 3\sqrt{0.25*0.75}[/tex]
Simplifying by 0.03 both sides
[tex]\sqrt{n} = 100\sqrt{0.25*0.75}[/tex]
[tex](\sqrt{n})^2 = (100\sqrt{0.25*0.75})^2[/tex]
[tex]n = 1875[/tex]
The sample size is 1875.

Each side of a square is increasing at a rate of 5 cm/s. At what rate (in cm2/s) is the area of the square increasing when the area of the square is 49 cm2
Answers
Answer:
25 cm^2/sec
Step-by-step explanation:
I my understanding of the question. It doesn't matter what the area of the square is currently is, for example if the area is 25 cm^2, 36 cm^2 or 49cm^2, the rate will ALWAYS increase by rate squared.
rate(a) x rate(b) = rate(area) in this case rate(a) = rate(b)
(5 cm^2/s) (5 cm^2/s) = 25 cm^2/s

So the principal collected data on overall physical activities throughout the week from a group of the sports program participants and a group of school A students not in the program. The most appropriate statistical test for data analysis would be:_______.
A. Paired-samples t test
B. Independent-samples t test
C. Pearson's correlation
D. One-sample t test
Answers
Answer:
B. Independent-samples t test
Step-by-step explanation:
The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.
Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.
Thus, the best test to use in this case will be the Independent-samples t test

complementary angles add up to equal 90
So to find the measure of angle 2 we subtract the given angle (33) from 90
90-33=57 so the measure of angle 2 = 57
Answer: 57°
Complementary Angles add up to 90°
Since we already have 33°, we need to find the other half.
90 - 33 = 57
It'll be 57°

Step-by-step explanation:

10×4=40+1=41, that will be your numerator (number at the top of the fraction) and the denominator 4 will stay the same. (bottom number)
[tex] \frac{41}{4} [/tex]
the base and the height will remain the same.
Formula : base × height = Area
[tex] \frac{41}{4} \times \frac{41}{4} = \frac{1681}{16} [/tex]
16 goes into 1681 105 times remainder 1.

A number is twice the other number. The sum of four times the smaller number and three times the larger number is 10. Find the numbers.
Please teach me how to do this. I'll give 90 points.
Answers
Answer:
1 and 2
Step-by-step explanation:
Let the first number be x
Let the other number be y
x = 2y.....eqn 1
From eqn 1, the smaller number is y while the bigger number is x.
3x + 4y = 10.... eqn 2
Substitute x = 2y into eqn 2
3(2y) + 4y = 10
6y + 4y = 10
10y = 10
Divide both sides by 10
y = 10/10
y = 1
Substitute y= 1 into eqn 1
x = 2y
x = 2(1)
x = 2
