Answer:

C) Jo's drink will have a stronger orange taste

Step-by-step explanation:

tropical punch calls for 2 liters of pineapple juice and 3 liters of orange juice.

total is 2+3 = 5 liters

pineapple = 2/5

orange = 3/5

Jo creates a drink by mixing 3 liters of pineapple juice with 4

total = 7

pineapple = 3/7

orange = 4/7

Get a common denominator to compare

5 and 7 = 35

tropical punch

pineapple = 2/5 *7/7 = 14/35

orange = 3/5*7/7 = 21/35

pineapple = 3/7*5/5 = 15/35

orange = 4/7*5/5 = 28/35

Jo will have both a stronger pineapple and orange taste than the tropical drink and the orange will be stronger than the pineapple in her drink

y = 2x + 14

Step-by-step explanation:

Hope this helps!!!

First, you have to find the slope by using

In other words,

The slope is 2.

Then you plug the rest into point-slope form (you can use either of the points, I used the first one)

Remember that m is the slope.

Distribute the slope to the parenthesis

Answer:

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Step-by-step explanation:

When the distribution is normal, we use 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:

$\mu_X = 45, \sigma_X = 4, \mu_Y = 35, \sigma_Y = 3$

What is the probability that a randomly generated value of X is greater than a randomly generated value of Y

This means that the subtraction of X by Y has to be positive.

When we subtract two normal variables, the mean is the subtraction of their means, and the standard deviation is the square root of the sum of their variances. So

$\mu = \mu_X - \mu_Y = 45 - 35 = 0$
