Answer: the answer is B.) 1080 sq in
Step-by-step explanation: edge 2021 i took the test
First, we get the z-score using formula:
z =( X - μ ) / σ
From the problem, we substitute the given values:
z = (9 - 7.8) / 1.7
z = 0.71
From the z-table (one-tailed), for a z-score of 0.7059, the proportion of numbers that are greater than 9 is 0.76.
Answer:
x = 47°
Step-by-step explanation:
From the picture attached,
CPD is a straight line.
Therefore, ∠CPB and ∠DPB is a linear pair of angles.
And linear pair of angles are supplementary.
By the property of linear pair of angles,
m∠CPB + m∠DPB = 180°
133 + x = 180
x = 180 - 133
x = 47°
