Answer:
The correct answer is 2.45.
Step-by-step explanation:
Probability model of an office manager regarding reports from employees is given by:
X = 0; P(X) = 0.05
X = 1; P(X) = 0.15
X = 2; P(X) = 0.35
X = 3; P(X) = 0.25
X = 4; P(X) = 0.15
X = 5; P(X) = 0.05
Now expectation of number of emails that the manager would receive is given by X × P(X)
= 0 × 0.05 + 1 × 0.15 + 2 × 0.35 + 3 × 0.25 + 4 × 0.15 + 5 × 0.05
= 0 + 0.15 + 0.70 + 0.75 + 0.60 + 0.25
= 2.45
Hiiiii ^-^ I can help you XD
Congruent
The same shape and size.
Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other.
In this example the shapes are congruent (you only need to flip one over and move it a little).
Angles are congruent when they are the same size (in degrees or radians).
Sides are congruent when they are the same length.
ANSWER: 569.5
All you have to do is make you % into a decimal is multiply by 850
Hope this helps :-)
Draw the diagram out in a way you understand it so yea
1/4 as a decimal is 0.25 (divide one by four). You can also multiply 1/4 by 52, but converting it into a decimal is typically easier.
"Of" typically means multiply, so multiply 52 * 0.25 to get the product 13.
For Option A., solve for 0.25 * 52, the final result should be 13.
For Option B., convert 4% into a decimal by dividing 4 over 100, you will get 0<span>.04, multiply 0.04 * 52 to get 2.08.
</span>
For Option C., divide 52 by 4, the quotient should be 13.
For Option D., 52 over 4 is another way to write 52 divided by 4, therefore, the answer, once again, is 13.
When comparing all the answers, you will notice all the answers are equal, except option B.
2.08 is not equal to 13
Therefore, your answer is <u>B. 4% of 52</u>
