Give three points that lie on a line with aslope of -2/5​

Mathematics
1 answer:
Luda [366]3 years ago
5 0

Answer:

The three points that lie on a line y = -2/5x with a slope -2/5 will be:

  • (0, 0)
  • (5, -2)
  • (10, -4)

Please check the attached graph also.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y = mx+b

where m is the slope and b is the y-intercept

Given

slope = m = -2/5

We suppose the line passes through the origin.

so b = 0

substituting m = -2/5 and b = 0 in the slope-intercept form

y = mx+b

y = -2/5x + 0

y = -2/5x

Thus, the equation of line with the slope m = -2/5 and passes through the origin (0, 0) will be:

y = -2/5x

As the equation of line passes through (0, 0), thus the point (0, 0) lies on the line.

Putting x = 0 in the equation y = -2/5x

y = -2/5 × (0)

y = 0

Thus, (0, 0) is the point which also passes through the line

Putting x = 5 in the equation y = -2/5x

y = -2/5 × 5

y = -2

Thus, (5, -2) is the point which also passes through the line

Now, putting x = 10 in the equation y = -2/5x

y = -2/5 × 10

y = -4

Thus, (10, -4) is the point which also passes through the line.

Thus, the three points that lie on a line y = -2/5x with a slope -2/5 will be:

  • (0, 0)
  • (5, -2)
  • (10, -4)

Please check the attached graph also.

A medical researcher says that less than 87​% of adults in a certain country think that healthy children should be required to
Lyrx [107]

Answer: It is not enough evidence to support the researcher's claim.

Step-by-step explanation:

Since we have given that

n = 500

\hat{p}=0.85

So, the hypothesis are as follows:

H_0:\hat{p}

So, the z value would be

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.85-0.87}{\sqrt{\dfrac{0.87\times 0.13}{500}}}\\\\z=\dfrac{-0.02}{0.015}\\\\z=-1.33

At α = 0.05

z= -1.64

So, 1.64<-1.33

So, we accept the null hypothesis.

Hence, it is not enough evidence to support the researcher's claim.

Find the measure of x, then find the measure of each angle​
stepladder [879]

First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:

180° = 90° + (x/2) + (7x - 90°)

180° = x/2 + 7x

180° = x *(1/2 + 7)

180° = x*(15/2)

2/15 * 180° = x

24 = x

Angle A:

A= x/2

A = 24/2

A = 12°

Angle B:

B = 7x

B = 7*24

B = 168°

The two bottom angles are both worth 90°.

Sixty percent of the customers who go to Sears Auto Center for tires buy four tires and 22% buy two tires. Moreover, 12% buy few
kozerog [31]

Answer:

A Cumulative probability distribution for the number of tires bought is prepared below.

Step-by-step explanation:

We are given that Sixty percent of the customers who go to Sears Auto Center for tires buy four tires and 22% buy two tires. Moreover, 12% buy fewer than two tires, with 6% buying none.

The cumulative probability distribution for the number of tires bought is given by;

   <u>No. of tires</u>       <u>Probability Distribution</u>      <u>Cumulative Probability</u>

                                                                                    <u>Distribution</u>

           0                               6%                                             6%

           1                                6%                                             12%

           2                               22%                                           34%

           3                                6%                                             40%

           4                               60%                                           100%

Now, here we are given within the question about:

P(0 tires) = 6%

P(2 tires) = 22%

P(4 tires) = 60%  

Also, P(Fewer than 2 tires) = 12% which means P(0 tires) + P(1 tire) must be equal to 12%. So, P(1 tire) = 12% - 6% = 6%.

And, in the end P(3 tires) = 100% - 6% - 6% - 22% - 60% = 6%.
