Step-by-step explanation:

Y-Y1=M(X-X1)

Y1,X1= POINTS GIVEN

M=SLOPE

Y-(-7)=-2/3(X-(1))

Y+7=-2/3(X-1)

Find the coordinates of point) along the directed segment AB that partitions it so that the ratio of AP to PB is 1:2. NO LINKS O

aleksandr82 [10.1K]

Answer: (1, 3)

Step-by-step explanation:

There are two ways to solve this problem, 1 without the pythagorean theorem, and 1 with it. For the sake of simplicity, I will solve it without the pythagorean theorem.

As is visually evident from the graph, the line segment spans 6 units horizontally, and 3 units vertically. Because the ratio between AP and PB is 1:2, simply divide both the domain and range by 3, to get 2 horizontally, and 1 vertically.

Then, simply go to point A and respectively add and subtract the horizontal and vertical values to get point A(-1, 4) --> P(1,3)

Hope it helps, and let me know if you want me to solve it an alternate way or go more in depth as to the way it is know.

Answer:

The answer is 126 $cm^{3}$

Step-by-step explanation:

The formula for the volume of a rectangle is L x W x H.

So you just plug in the numbers into the formula.

2 x 9 x 7

That equals 126.

Suppose that the mean and standard deviation of the scores on a statistics exam are 78 and 6.11, respectively, and are approxima

kiruha [24]

Answer:

0.7422 = 74.22% of scores are above 74.

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:

$\mu = 78, \sigma = 6.11$
