Equation 2 is 6 times the equation 1.

<u>Explanation:</u>

Given:

-5x - 8y = 4 -1

-30x - 48y = 24 -2

The 2nd equation can be simplified in following steps:

-30x - 48y = 24

Dividing both left and right hand side by 2. We get

-15x - 24y = 12

Dividing the equation further by 3 on both the sides. We get

-5x - 8y = 4 -3

We can see that on simplification of equation 2, it becomes same as equation 1.

Therefore, equation 2 is 6 times the equation 1.

$A_1=59+11(1)$

$A_1=70$

$A_2=59+11(2)$

$A_2=81$

$A_3=59+11(3)$

$A_3=92$

$A_4=59+11(4)$

$A_4=103$

Nesterboy [21]

Answer:

Option A.

Step-by-step explanation:

We need to find the residual for a student with an observed BMI of 25 and an observed hrs/month under the influence of 18.8.

Actual value = 25

Predicted value = 18.8

Residual = Actual value - Predicted value

Residual = 25 - 18.8

Residual = 6.2

Round the answer to two decimal places.

Residual = 6.20

The residual value is 6.20.

Therefore, the correct option is A.

Viktor [21]

Answer:

P-value = 0.032794

Step-by-step explanation:

We are given the following information in the question:

Population mean, μ = 98.6 degrees

Sample size, n = 9

Alpha, α = 0.05

Test t-statistic = 2.132

The null and the alternate hypothesis :

$H_{0}: \mu = 98.6\text{ degrees}\\H_A: \mu > 98.6\text{ degrees}$

We have to find the p-value for degree of freedom 8 and significance level 0.05

The calculated p-value is 0.032794
