Answer:
0.89417
Step-by-step explanation:
Using the relation to obtain the Zscore :
Z = (x - mean) ÷ standard deviation / sqrt(n)
x = 0.8535
Mean = 0.8565
Standard deviation = 0.0518
Sample size, n = 465
P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)
P(x ≥ 0.8535) = - 0.003 / 0.0024021
P(x ≥ 0.8535) = - 1.249
P(Z ≥ - 1.249) = 0.89417

Step-by-step explanation:
The formula for finding the area of a circle is;
Where () represents the area of the circle, () represents the value () and () represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.
This means that the radius for the given circle is (), since (÷)
Substitute these values into the equation and solve for the area of the circle.

Answer:
C. 19a + 11b
Step-by-step explanation:
Distribute into the parentheses.
3(5a + b) + 4(a + 2b)
= 15a + 3b + 4a + 8b
Add like terms.
15a + 3b + 4a + 8b
19a + 3b + 8b
= 19a + 11b
Hope that helps.
