200 inches bc 10x10 +10x10 is 200
√13 - √11
The last answer.
Wouldn't you just do 10 divided by 12
I would solve this using tangents. Let h be height of flagpole.
Set up 2 right triangles, each with a base of 40.
The larger triangle has height of "h+70"
Smaller triangle has height of 70.
Now write the tangent ratios:
Note: A-B = 9
To solve for h we need to use the "Difference Angle" formula for Tangent
Plug in what we know:
Answer: B.
Step-by-step explanation:
Let be the proportion of all U.S. adults that smoked in 1995. Let denote the proportion of all U.S. adults that smoked in 2000.
Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.
i.e.
Alternative hypothesis is the statement containing population parameter that shows there is significant difference between the groups being tested.
⇒
Null hypothesis is the statement containing population parameter that shows there is no significant difference between the groups being tested.
⇒
Hence, The hypotheses to test in this problem are
Hence, the correct answer is B.
