Since the shape is a square pyramid, the base would be 14 by 14. The area of one triangle would be 10 times 14 times 1/2 = 70. 70 times 4 = 280. 14 times 14 = 196
196 + 280 = 476
Final answer = 476

Test the claim that the proportion of men who own cats is larger than 20% at the .005 significance level. The null and alternative hypothesis would be:_____.
A. H0: p = 0.2
Ha: p is not equal to 0.2.
B. H0: mu = 0.2
Ha: mu is not equal to 0.2.
C. H0: p = 0.2
Ha: p < 0.2.
D. H0: mu = 0.2
Ha: mu < 0.2
E. H0: mu = 0.2
Ha: mu > 0.2.
The test statistic is:____.
The critical value is:____.
Based on this we (to 2 decimals) (to 2 decimals):_____.
a. reject the null hypothesis.
b. fail to reject the null hypothesis.
Answer:
[tex]C. \\ \\ H_o: p = 0.2 \\ \\ Ha: p < 0.2[/tex]
Step-by-step explanation:
From the given information:
Null & Alternative hypothesis is:
[tex]\ \\ H_o: p = 0.2 \\ \\ Ha: p < 0.2[/tex]
Since the alternative hypothesis is less than 0.2;
Then, the test is left-tailed.
The level of significance ∝ = 0.005
Let assume that:
the sample size n of the people = 55 and there are 19 owned cats;
Then:
Test statistics:
[tex]Z =\dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]
[tex]Z =\dfrac{0.19 - 0.2}{\sqrt{\dfrac{0.2(1-0.2)}{55}}}[/tex]
[tex]Z =\dfrac{- 0.01}{\sqrt{\dfrac{0.16}{55}}}[/tex]
[tex]Z =\dfrac{- 0.01}{\sqrt{0.002909}}[/tex]
Z = - 0.18540
Z = - 0.19
At ∝ = 0.005; the critical value [tex]Z_{\alpha/2}= Z_{0.005/2}= -2.58[/tex]
Since the value of the test statistics is greater than the critical value; then, we fail to reject [tex]H_o[/tex] i.e the null hypothesis.

A spinner has 10 equal sections numbered 1 through 10. What is the probability of
landing on the 6?
A. 1/2
B:9/10
C.1/10
D.4/10
Answer:
The correct answer is C. 1/10.
Step-by-step explanation:
Given that a spinner has 10 equal sections numbered 1 through 10, to determine what is the probability of landing on the 6, the following calculation must be performed:
6 = 1 side only
10 = 10 options
1/10 = X
Therefore, the probability of the spinner landing on the 6 is 1/10.

Answer:
[tex]\huge\boxed{\sf h = 26.684\ feet}[/tex]
Step-by-step explanation:
See the attached file along with the solution.
Let the height be h,
base of triangle 1 be x
base of triangle 2 be 100 - x
Using the following trigonometry for both the triangles.
[tex]\displaystyle tan (\theta) = \frac{opposite}{adjacent}[/tex]
For triangle 1:
tan 20 = h / x ---------------------(1)
For triangle 2:
tan 45 = h / 100 - x -----------------(2)
Taking Eq. (1)
tan 20 = h / x
Multiply both sides by x
tan 20 * x = h
h = tan (20) * x
h = 0.36397x -----------------------(3)
Put Eq. (3) in (2)
tan (45) = 0.36397x / 100-x
1 = 0.36397 x / 100 - x
Multiply both sides by 100 - x
100 - x = 0.36397 x
Add x to both sides
100 = 0.36397 x + x
100 = 1.36397 x
Divide both sides by 1.36397
100 / 1.36397 = x
73.315 = x
x = 73.315 feet
Now, Finding h (height):
tan 20 = h / x (Eq. (1))
h = tan (20) * x
h = 0.36397 * 73.315
h = 26.684 feet

Step-by-step explanation:
IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 60 students attend a series of coaching classes before taking the test. Let μ be the population mean IQ score that would occur if every student took the coaching classes. The classes are successful if μ > 100. A test is made of the hypotheses H0: μ = 100 versus H1: μ > 100. Consider three possible conclusions: (i) The classes are successful. (ii) The classes are not successful. (iii) The classes might not be successful.
a. Which of the three conclusions is best if H0 is rejected?
b. Which of the three conclusions is best if H0 is not rejected?
c. Assume that the classes are successful but the conclusion is reached that the classes might not be successful. Which type of error is this?
d. Assume that the classes are not successful. Is it possible to make a Type I error? Explain.
e. Assume that the classes are not successful. Is it possible to make a Type II error? Explain.
Answer:
a.) The classes are successful
b.) The classes might not be successful.
c.) Type 11 error
d.) Yes
E.) No
Step-by-step explanation:
C.)
This means that we failed to reject H0 when it is actually FALSE and in fact the classes are successful , that means mean μ > 100, that is: null hypothesis is False.
D.)
Type 1 error occurs when we incorrectly reject H0 ; that is we rejected H0, when it is true
Here, H0, means the classes aren't successful, hence, incorrectly rejecting H0 means we have committed a type 1 error
E.)
Type 11 error means failing to reject H0
;
Here, H0, means the classes aren't successful,
Hence, if we fail to reject H0 in this scenario, we are right, hence, there is no possibility of making a type 11 error in this scenario

Question 4 options:
6
18.5
24
11
Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11
