Answers
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.
What is the expected value?In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.
Then the probability of the oranges that weigh 5 ounces is given as,
p = 2/25
Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,
E(x) = 700 x 2 / 25
E(x) = 28 x 2
E(x) = 56
The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.
Answers
Answer:
P = 60
Step-by-step explanation:
First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.
25 5
---- = ----
15 3
So the larger triangle is 5/3 times bigger.
This means that all of its other sides with also be 5/3 times bigger.
So:
9 (5/3) = 45/3 = 15
12 (5/3) = 60/3 = 20
25 + 15 + 20 = 60
So the perimeter is 60.
You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:
36 (5/3) = 180/3 = 60
You would get the same thing.

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.
3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.
Radius of Outer circle:
2.2 is the diameter so find the radius, divide by 2 = 1.1
Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.
