The answer is A, because Men represent 55% of survey respondents, but they represent 475/850 = 56% of those with higher incomes. The answer options include an explanation which says that the conditional probability is not equal to the population probability.
Answer:
X=-5 or X=1
Step-by-step explanation:
f(x)=(x+5)(x-1)
(x+5)(x-1)=0
x=-5 orx=1
The test statistics and the p-value from the research sampling will be 1.57 and 0.119.
<h3>What is test statistic?</h3>
It should be noted that a test statistic simply means a number that's used to describe how the observed value is far from the null hypothesis.
In this case, the test statistics is 1.57. The p value will be:
= 2 × 0.0593
= 0.119
Therefore, the test statistics and the p-value from the research sampling will be 1.57 and 0.119.

Answer:
Q1
cos 59° = x/16
x = 16 cos 59°
x = 8.24
Q2
BC is given 23 mi
Maybe AB is needed
AB = √34² + 23² = 41 (rounded)
Q3
BC² = AB² - AC²
BC = √(37² - 12²) = 35
Q4
Let the angle is x
cos x = 19/20
x = arccos (19/20)
x = 18.2° (rounded)
Q5

Added point D and segments AD and DC to help with calculation
BC² = BD² + DC² = (AB + AD)² + DC²
Find the length of added red segments
AD = AC cos 65° = 14 cos 65° = 5.9
DC = AC sin 65° = 14 sin 65° = 12.7
Now we can find the value of BC
BC² = (19 + 5.9)² + 12.7²
BC = √781.3
BC = 28.0 yd
All calculations are rounded
