While preparing for a party a party planner began with 75 pieces of candy she ate 5 pieces while she was working then she put eq

Sloan [31]

The easiest way to find this answer is to work through it step by step.

She starts with 75 pieces.

She eats 5 pieces, so the # of pieces goes down from 75 to 75-5 = 70.

So she has 70 pieces left to put in the bags.

She puts the same amount in each of 10 bags... so we divide 70 by 10 to find the # of pieces in each bag.

70 divided by 10 is 7.

She put 7 pieces in each bag.

Number 3 please! pic is above^

zmey [24]

Answer:

Step-by-step explanation:

Slope = (y2 -y1)/(x2-x1)

y2 = 800, y1 = 400, x2= 4, x1= 2

Slope = (800-400)/(4-2)

= 400/2

= 200calories/hr

The diameters of ball bearings are distributed normally. The mean diameter is 83 millimeters and the standard deviation is 3 mil

Alenkinab [10]

Answer:

0.2514 = 25.14% probability that the diameter of a selected bearing is greater than 85 millimeters.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 83, \sigma = 3$

Find the probability that the diameter of a selected bearing is greater than 85 millimeters.

This is 1 subtracted by the pvalue of Z when X = 85. Then

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{85 - 83}{3}$

$Z = 0.67$

$Z = 0.67$ has a pvalue of 0.7486.

1 - 0.7486 = 0.2514

0.2514 = 25.14% probability that the diameter of a selected bearing is greater than 85 millimeters.

75g og corn flakes provides 27 calories. how many calories are in 120g of cornflakes

strojnjashka [21]

If you divide 27 by 75 you will get .36 calories. .36 is how many calories are in one gram of corn flakes. So if you multiply .36 and 120 you will get 43.2 therefore there is 43.2 calories in 120 grams of corn flakes.
