Answer:

It has infinite solution

Step-by-step explanation:

y = 2x +10 is already in slope intercept for so we move on to 3y-6x= 30.

The slope of 3y-6x =30 is 2 and if you solve for y, it's going to be 10.

If you put it in slope intercept form, it's going to be y = 2x+10 which is the

same as the first one.

Answer: it has an infinite amount

Step-by-step explanation:

when you simplify 3y - 6x = 30 it equals

y = 2x + 10

Maurinko [17]

Hello,

The correct answer is B) 280 in²

= 10( 2 × 9 + 10 )

= 10 (2 × 9 = 18 + 10 = 28)

= 10 × 28 = 280

= 280

Answer: 280 in²

In other words.....

= 10(2*9+10)

= 10(18+10)

= 10*28

= 280

Answer: 280 in²

Hope this helps!!!! (:

Answer:

For the 99th percentile, we have X = 206 seconds.

Step-by-step explanation:

Problems of normally distributed samples can be solved using 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 problem, we have that:

\mu = 138.5, \sigma = 29

99th percentile:

Value of X when Z has a pvalue of 0.99. So we use Z = 2.325

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

2.325 = \frac{X - 138.5}{29}

X - 138.5 = 29*2.325

X = 205.92 = 206

For the 99th percentile, we have X = 206 seconds.
