Let X be a random variable representing the weight of
strawberries.
<span>
μ= 12</span>
σ= 2.5
Solution:
<span>
P(X < 10) = P(z < (10 - 12)/2.5) </span>
= P(z < -2/2.5)
= P(z < -0.8)
= 1 - P(z < 0.8)
= 1 - 0.7881
= 0.2119
<span>The answer is letter B.</span>
Answer:
The area of the sector (shaded section) is 29.51 .
Step-by-step explanation:
Area of a sector = (θ ÷ 360)
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r =
= = 13 m
θ = 360 - (180 + 160)
= 360 - 340
=
Thus,
area of the given sector = x x
= x x x 169
= 29.5079
The area of the sector (shaded section) is 29.51 .
Answer:
972
Step-by-step explanation:
The first term is (9x)^3, so the coefficient of x is 9. Since the degree is 3, the second term must have a multiplier of (3 choose 1). 1458 / (3 choose 1) = 486.
486 / (9^2) = 6. Therefore, the coefficient of y must be 6. Since the second term is negative, the coefficient of y is also negative. Thus, this can be written as (9x-6y)^3. Solving for the xy^2 term gives us (3 choose 2) * 9 * 6^2 = or the third option.
