# 3) You are in charge of arranging the catering for a company meeting. Your company is responsible for paying for all meals ordered, so you don't want to order too many. Suppose that the expected number of people for the meeting is 84, with a standard deviation of 4 people. What is the fewest number of meals should you order so that the probability of having more people than meals is 5%? 0

84

Step-by-step explanation:

Sample size = 84 and standard deviation = 4

This means number of people can be 84 +- 4 or 80 to 88

Let the number of meal be X.

probability of having more people than meals is 5%

Z score = X-mean/ sigma = (X - 84)/4 = 5% of X  = X/5

5X -84 = 4X

X = 84

620

Step-by-step explanation:

using partial quotients 620 would be the best choice for the first number to subtract in the division problem 9176 divided by 31.

The factor or the number with which the divisor is multiplied is the partial quotient. So, we keep multiplying the divisor with a number and subtract that product from the dividend until the difference is less than the divisor or equal to 0.

none;

constant.

Explanation:
For this case, the first thing we must do is observe the relationship between the variables:
Independent variable: Weight of the box (ounces);
Dependent variable: Price of the box (\$).
Observing the behavior between both variables, we see that there is no specific relationship between the increase or decrease in the weight of the box and the increase or decrease in the price.
Therefore, there is no correlation between the variables. Mathematics

1.075h

Step-by-step explanation:

Given that :

Juan's initial hourly rate of pay = h

% increase = 7.5%

So, increase = 7.5% of h = 0.075 × h = 0.075h

Thus,

New hourly rate = Initial hourly rate + Increase

= h + 0.075h

= 1.075h

Thus, the new hourly rate is 1.075h.
