Find the slope of the following graphs

Mathematics
1 answer:
hodyreva [135]3 years ago
6 0

Answer:

Slope = -1

Step-by-step explanation:

The equation we use for slope is as follows:

m = (y2 - y1) / (x2 - x1)

The graph gives us four points, but we only need two to solve our equation: (-2,5) and (2,1)

Now, we need to define which variable goes with which point:

Y2 = 1

X2 = 2

Y1 = 5

X1 = -2

If we plug these into our equation we get the following:

m = (1 - 5) / (2 - -2)

m = (-4) / (-4)

m = -1

Our slope for this graph = -1

I hope this helps!

Write an ordered-pair rule for the translation in the sequence that maps AEFG to AE'F'G'. 4 Points ANSWER: Translation rule: (x,
Anastasy [175]

The translation rule is:

(x,y) \rightarrow (x + 4, y - 5)

  • F(1,4) is mapped to F'(5,-1), that is, 4 is added to the x-coordinate and 5 is subtracted from the y-coordinate.
  • G(2,2) is mapped to G'(6,-3), which is the same change as in F.
  • The same happens for E(-1,2), which is mapped to E'(3,-3).

Thus, the translation rule when <u>4 is added to the x-coordinate and 5 is subtracted from the y-coordinate</u> is:

(x,y) \rightarrow (x + 4, y - 5)

The slopes of the sides of quadrilateral ABCD are shown in the table below.
fredd [130]

Answer:

B) AB is parallel to CD, but AD is not parallel to BC.

Step-by-step explanation:

The options are:

A) AD is parallel to BC, but AB is not parallel to CD.

B) AB is parallel to CD, but AD is not parallel to BC.

C) AB is parallel to CD, and AD is parallel to BC.

D) AD is not parallel to BC, and AB is not parallel to CD.

AB and CD have the same slope, so they are parallel.

BC and AD have different slopes, so they are not parallel.

Therefore, the answer is B.

Lemur [1.5K]

Answer:

4.65% probability that a randomly selected customer takes more than 10 minutes

Step-by-step explanation:

Problems of normally distributed samples are 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 question, we have that:

\mu = 7.45, \sigma = 1.52

Probability that a customer takes more than 10 minutes:

This is 1 subtracted by the pvalue of Z when X = 10. So

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

Z = \frac{10 - 7.45}{1.52}

Z = 1.68

Z = 1.68 has a pvalue of 0.9535

1 - 0.9535 = 0.0465

4.65% probability that a randomly selected customer takes more than 10 minutes
