Answer:
d, 3 5/8
Step-by-step explanation:
Answer:
J and K are supplementary
Step-by-step explanation:
Given
The attached image
Required
The true statement
From the attached image, it is hard to determine the values of angles I and L as there are no enough information to determine their values.
However, J and K can be worked easily.
From the image
--- vertically opposite angles
And:
---- angle on a straight line
Substitute: 

When two angles add up to 180, the angles are supplementary.
<em>Hence, (c) is correct</em>
Answer:
Option D) There is sufficient evidence that the true population proportion is not equal to 70%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1165
p = 70% = 0.7
Alpha, α = 0.02
Number of people who agreed , x = 746
First, we design the null and the alternate hypothesis
This is a two-tailed test.
Formula:
Putting the values, we get,
Now,
Since,
Since, the calculated z statistic does not lie in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Thus, there is enough evidence to support the claim that the true proportion differs from 70%.
Option D) There is sufficient evidence that the true population proportion is not equal to 70%.
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
