Two points on slide are (0, 80), (5, 40).

Step-by-step explanation:

The graph shows the side view of a waterslide and its dimensions are in feet.

First to find (0, ___) and then to find (____, 40).

In the first point x-coordinate is 0 and y-coordinate for the corresponding x-coordinate is 80.

In the second point y-coordinate is 40 and the x-coordinate for the corresponding y-coordinate is 5.

So, the two points are (0, 80), (5, 40).

Marcus has a pool that can hold a maximum of 4500 gallons of water. The pool already contains 1500 gallons of water. Marcus begi

Murljashka [212]

First, let's subtract the whole pool by the water currently in to find the water needed to fill it:
4500 - 1500 = 3000
Because we need to represent an inequality:
30m = 3000
Divide both by 30:
m = 100

Greeley [361]

Answer:

Emma made a mistake. The slope should be -40.

Step-by-step explanation:

Pair of points (x, y):

(165, 900) and (180, 300)

Slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

Calculate the slope:

Slope = (300 - 900)/(180 - 165) = -600/15 = -40

A brewery produces cans of beer that are supposed to contain exactly 12 ounces. But owing to the inevitable variation in the fil

MArishka [77]

Answer:

$T \sim N (\mu = 6*12=72 , \sigma= \sqrt{6} *0.3=0.735)$

$P(T \leq 72) = P(Z< \frac{72-72}{0.735}) = P(Z$

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solutio to the problem

Let X the random variable that represent the amount of beer in each can of a population, and for this case we know the distribution for X is given by:

$X \sim N(12,0.3)$

Where $\mu=12$ and $\sigma=0.3$

For this case we select 6 cans and we are interested in the probability that the total would be less or equal than 72 ounces. So we need to find a distribution for the total.

The definition of sample mean is given by:

$\bar X = \frac{\sum_{i=1}^n X_i}{n} = \frac{T}{n}$
