Alex787 [66]3 years ago
7 0

Answer:

Step-by-step explanation:

7) (4 , 7)

Slope of the line passing through (0, 3) and (2,5) = \frac{5-3}{2-0}=\frac{2}{2}=1

Point lying on this line will have the same slope

(0,3) and (4,7)

Slope= \frac{7-3}{4-0}=\frac{4}{4}=1

(4, 7) lies on this line.

8) (2 , 2)

Slope of the line passing through (-2,10) and (1,4) = -2

(2, 2)  & ( 1, 4)

Slope = \frac{4-2}{1-2}=\frac{2}{-1}=-2

(2, 2) lies on this line

pentagon [3]

The probability of observing the experiment result, a sample mean, for example, or something more unusual just by chance if the null hypothesis is true is the definition of "P-Value."

<h3>What is null hypothesis?</h3>

A null hypothesis is a sort of statistical hypothesis which asserts that there is no statistical significance in a particular set of observations.

Using sample data, hypothesis testing is performed to determine the believability of a theory. It really is expressed as H0 and is also known to simply as "null."

Some key features regarding null hypothesis are-

  • A null hypothesis is a statistical conjecture that claims there is no variation between particular qualities of a population and data-generating process.
  • The alternate hypothesis asserts the existence of a distinction.
  • Hypothesis testing allows you to reject the null hypothesis with a particular level of confidence.
  • If the null hypothesis can be rejected, it lends support to the alternative hypothesis.
  • The notion of falsity in science is founded on null hypothesis testing.

On Mars, 3 bags of MartianMallows cost 24 space rocks. If each bag contains 10 MartianMallows, how many space rocks does four Ma
harina [27]

Answer:

16/5

Step-by-step explanation:

If each bag contains 10 MartianMallows, then 3 bags contain (3)(10)=30 MartianMallows. Since we know that the cost of 30 MartianMallows is 24 space rocks, we can set up the proportion 24/30=s/4, where s is the cost of four MartianMallows. Solving for s, we find that s=24/30*(4)={16/5 space rocks.

Factorise x(6x - 5y) - 4(6x - 5y)^2
Fed [463]

Answer:

(6x-5y)(20y-23x)

Step-by-step explanation:

x(6x - 5y) - 4(6x - 5y)^2

= (6x-5y)(x-4(6x-5y))

= (6x-5y)(x-24x+20y)

= (6x-5y)(20y-23x)

Write the slope intercept form of the equation of each line plz
rosijanka [135]

Answer:  B.    y = -13/6x + 8  

Step-by-step explanation:

13x + 6y = 48    subtract 13x from both sides

-13x           -13x

  6y = -13x + 48      Divide both sides by 6  

   y = -13/6x + 8
