Draw a diagram. Then use tan(x) to find the remainder height of the taller building.
Answer:
Yes
Step-by-step explanation:
7/13*2=14/26
13/26=1/2

Answer with explanation:</h2>
Let p be the population proportion.
Then, Null hypothesis : 
Alternative hypothesis : 
Since the alternative hypothesis is right tailed , then the hypothesis test is a right tailed test.
Given : A random sample of 200 high school seniors from this city reveals that 162 plan to attend college.
i.e. n = 200 > 30 , so we use z-test (otherwise we use t-test.)

Test statistic for population proportion :


Thus, the z-value of the sample test-statistic = 0.72
P-value for right tailed test =

Since the p-value is greater than the significance level (0.05) , so we fail to reject the null hypothesis.
Hence, we conclude that we do not have sufficient evidence to support the claim that the percentage has increased from that of previous studies.
The answer
let be
A1 = (2x^4-3x^3+2x+4)-(-x^4-3x^3+4x^2+x+3) =
= 2x^4-3x^3+2x+4 +x^4 +3x^3- 4x^2- x-3
A1= 6x^4 -2x² +x +1
and
A2= 5x^4-2x^3+3x^2+3x-4-(2x^4-2x^3+7x^2+2x-5)
= 5x^4-2x^3+3x^2+3x-4-2x^4+2x^3-7x^2-2x+5
A2<span>= 3x^4-4x²+x+1
A1 is not equivalent to A2
so the answer is </span><span>B. False </span>
