Explain why the slope of line a is 2/6​

Mathematics
1 answer:
nevsk [136]3 years ago
3 0

Answer:

Step-by-step explanation:

Hi so 2/3

where slope means rise over run

so  it means the first point or you slope(x1 y1)

and you take that point, go up 2 on Y, and move 6 unit to the left(x)

Parallelograms geometry acellus pls help
Mamont248 [21]

Answer:

x = 60

Step-by-step explanation:

Recall: one of the properties of a parallelogram is that consecutive angles are supplementary. This means they add up to given 180°

2x and x are consecutive angles. Therefore:

2x + x = 180

3x = 180

Divide both sides by 3

3x/3 = 180/3

x = 60

Claim: The standard deviation of pulse rates of adult males is less than 11 bpm. For a random sample of 132 adult​ males, the pu
seraphim [82]

Answer:

\chi^2 =\frac{132-1}{121} 114.49 =123.952

Step-by-step explanation:

Notation and previous concepts

A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"

n=132 represent the sample size

\alpha represent the confidence level  

s^2 =10.7^2 =114.49 represent the sample variance obtained

\sigma^2_0 =11^2=121 represent the value that we want to test

Null and alternative hypothesis

On this case we want to check if the population variance specification is violated, so the system of hypothesis would be:

Null Hypothesis: \sigma^2 \geq 121

Alternative hypothesis: \sigma^2

Calculate the statistic  

For this test we can use the following statistic:

\chi^2 =\frac{n-1}{\sigma^2_0} s^2

And this statistic is distributed chi square with n-1 degrees of freedom. We have eveything to replace.

\chi^2 =\frac{132-1}{121} 114.49 =123.952

Calculate the p value

In order to calculate the p value we need to have in count the degrees of freedom , on this case 131. And since is a right tailed test the p value would be given by:

p_v =P(\chi^2

In order to find the p value we can use the following code in excel:

"=1-CHISQ.DIST(123.952,131,TRUE)"

A bag of marbles contains 28 red marbles, 30 green marbles, and 24 yellow marbles. What is the ratio of red marbles to yellow ma
Basile [38]

Answer:

The answer to your question is 7:6

Step-by-step explanation:

Data

Number of red marbles = 28

Number of green marbles = 30

Number of yellow marbles = 24

Radio = ?

Process

1.- Write the ratio

                   Red marbles : Yellow marbles

2.- Substitution

                                  28 : 24

3.- Simplification

-Divide both terms by 2

                                  14 : 12

-Divide by two both terms

                                    7 : 6

-It is not possible to simplify more.
