Solve this system of linear equations. Separate the x- and y-values with a comma. -3x=42-16y 14x=76-16y

myrzilka [38]

Answer:

$(2,3)$

Step-by-step explanation:

The given equations are:

1st: -3x=42-16y

2nd: 14x=76-16y

Subtract the first equation from the second one:

14x--3x=76-42-16y--16y

14x+3x=34-16y+16y

17x=34

$x=\frac{34}{17}=2$

We plug in x-value into the second equation to get:

14(2)=76-16y

14x=76-32

28-76=-16y

-48=-16y

Divide both sides by -16

y=3

The weights of college football players are normally distributed with a mean of 200 pounds and a standard deviation of 50 pounds

Feliz [49]

Answer:

0.3811 = 38.11% probability that he weighs between 170 and 220 pounds.

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, we have that:

$\mu = 200, \sigma = 50$
