Remark
Set up a proportion for this problem. Solve the proportion.

Givens
3 cups make 4 waffles.

Solve
How many cups does it take to make 12 waffles.

Proportion
3 cups:4 waffles :: x: 12 waffles.

Solve
3/4 = x / 12 Cross multiply
3*12 = 4*x Multiply the factors on the left.
36 = 4x Divide by 4
36/4 = x
9 = x

Laundry detergent boxes are filled according to an approximately Normal distribution with mean 34.15 ounces and standard deviati

Leno4ka [110]

Using the normal distribution, it is found that there is a 0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

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

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 34.15, \sigma = 0.1$ .

The probability a randomly selected box has less than the 34 ounces of advertised weight is the <u>p-value of Z when X = 34</u>, hence:

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

$Z = \frac{34 - 34.15}{0.1}$

Z = -1.5

Z = -1.5 has a p-value of 0.0668.

0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.

Find the surface area of the rectangular prism. 5ft tall 5 feet long 2 feet wide

Mars2501 [29]

Answer:

46.25 feet squared

Step-by-step explanation:

base area = 5x2 = 10

you need to find how tall the faces of the prism are now. You can do this using the pythagorean theorem: a^2+b^2=c^2

5^2+2.5^2=c^2 and 5^2+1^2=c^2

(since it is a rectangular pyramid)

c= 5.60 and c= 5.01

now be can find the surface area of the 4 triangles

SA= 5.60x2 and SA= 5.01x5

SA=11.2 and SA= 25.05

add all the components (11.2, 25.05, 10) together to get the final surface area: 46.25

Answer:

2 + 3 (1) + (10 / 5)^2 + 7 - 6 = 10

Step-by-step explanation:

2 + 3 (1) + (10 / 5)^2 + 7 - 6

= 2 + 3 + (2)^2 + 7 - 6

= 2 + 3 + 4 + 7 - 6

= 10
