The probability of randomly selecting an order that has at least 760

calories is 0.16

Step-by-step explanation:

The number of calories in an order of poutine at a certain fast food

restaurant is approximately normally  distributed

1. The mean "μ" is 740 calories

2. The standard deviation "σ" is 20 calories

3. We need to find the probability of randomly selecting an order that

    has at least 760 calories (x ≥ 760)

At first let us calculate z-score

∵ z = (x - μ)/σ

∵ x = 760 calories

∵ μ = 740 calories

∵ σ = 20 calories

∴ z = \frac{760-740}{20}=1

Use the normal distribution table of z (area to the left of z-score) to

find the corresponding area to z-score of 1

∵ The area corresponding of z = 1 is 0.84134

∵ We interested in x ≥ 760, we need the area to the right of z-score

∴ P(x ≥ 760) = 1 - 0.84134

∴ P(x ≥ 760) = 0.15866 ≅ 0.16

The probability of randomly selecting an order that has at least 760

calories is 0.16

851-473 is the same as ___[dash]-470
Degger [83]
First figure out what 851 minutes 473 equals to, which is 378


So both sides of the equation should equal to 378

Plus 470 and 378 together

Which equals to 848

So the answer is eight hundred and forty eight

The length of a parking lot is 7 yards more than the width.If the area of the parking lot is 98 square yards,find the dimensions
USPshnik [31]
The parking lot is 14 yards long by 7 yards wide.

A = W x L       The formula is ....

L = W + 7        The problem tells us that ...

A = W (W + 7)
A = w^2 + 7w
98 = w^2 + 7x
... continue from there
