The graph shows a proportional relationship between a​ family's distance from home and the time they spent driving. What is the constant of​ proportionality? What does the point​ (1,49) represent?

Answers

Answer:

Step-by-step explanation:

Graph shows the proportional relationship between a family's distance from home and the time spent by them in driving.

Distance from home ∝ time

Distance from home = k(time)

Here 'k' = proportionality constant

For a point (1, 49) on the graph,

49 = k(1)

k = 49 miles per hour

And point (1, 49) will represent 49 miles in 1 hour.

Option (3) is the answer.

if the length of a rectangle is 3 times of its breadth and perimeter is 96 cm find the length and breadth of the rectangle​

Answers

Length=36 cm

Breadth/width=12cm

So the rectangle is 3x by x

We are given the perimeter, so well solve with that.

All four sides equal 3x+x+3x+x=8x

So 8x=96

When we solve for x, we get x=12

Since x=12, we know this is the breadth.

We know 3 times this is the length so:

12x3=36!

Answer:14 or 0.25

Step-by-step explanation:

It’s basically already written there but decimal form is 0.25

Different dealers may sell the same car for different prices. The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively. Suppose we select one of these cars at random. Let X= the sale price (in thousands of dollars) for the selected car. Find P(X>25), left parenthesis, X, is greater than, 25, right parenthesis. You may round your answer to two decimal places.

Answers

Answer:

P(X > 25) = 0.69

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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.

The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively.

This means that [tex]\mu = 26, \sigma = 2[/tex]

Find P(X>25)

This is 1 subtracted by the pvalue of Z when X = 25. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 26}{2}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a pvalue of 0.31

1 - 0.31 = 0.69.

So

P(X > 25) = 0.69

5x+y=2
x+y=10​

Answers

Answer:

try symbolab calculator it will give you a step by step explanation

Answer:

x= -2

y= 12

Step-by-step explanation:

5x + y = 2..................eqn 1

x + y = 10 ..................eqn 2

from eqn 1

5x + y = 2, u substitute by making 'y' the subject

y = 2 - 5x .................eqn 3

put eqn 3 into eqn 2

x + y = 10

x + 2 - 5x = 10

x - 5x = 10 - 2

-4x = 8

x = 8 / -4

x = -2

put x = -2 into eqn 1

5x + y = 2

5(-2) + y = 2

-10 + y = 2

y = 2 + 10

y = 12
