Answer:
C.
Step-by-step explanation:
Also known as left-skewed distribution, a negatively skewed distribution would have data that are more concentrated on the right side. So you would see a longer tail on the left-side of the distribution or curve. You would find the mean to the left of the median of the data.
°C = 5/9 (°F - 32)
°C = 5/9 (38 - 32)
= 5/9 (6)
= 30/9 = 3 e 1/3 .
Answer:
∠ XYZ ≈ 66.4°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosY = = = , then
∠ Y = ( ) ≈ 66.4° ( to 1 dec. place )
Answer:12.59
Step-by-step explanation:

From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.
