To find

So, according  to the question

We have,

So, we know that

               mean = [tex]\frac{sum\;of\;\;data}{number\;of\;data}[/tex]

                   ∑ Ta =  29+ 38+ 39+ 26+ 29+ 29+ 39+ 77+ 38+ 29

                   ∑ Ta =  373

                     Tn =  10        

Now, The Mean of teachers ages

                     Tm =  [tex]\frac{sum\;of\;the\;teachers\;ages}{number\;of\;teachers}[/tex]

                     Tm =  [tex]\frac{T_a}{T_n}[/tex]

                            =  [tex]\frac{373}{10}[/tex]

                     Tm  =  37.30

A) The expression for the number of tires used to make x lane-miles of asphalt rubber is y = 2000x.

B) The number of tires used to make 11, 50, and 150 lane-miles of asphalt rubber are as follows:

y =  22000

y = 100000

y = 300000

Approximately 2000 tires are recycled to produce one lane-mile of asphalt rubber.

Therefore, an expression for the number of tires used to make x lane-miles of asphalt rubber is as follows:

y = 2000x

where;

x = number of lanes-miles

y = number of tires

Therefore, the number of tires used to make 11, 50, and 150 lane-miles of asphalt rubber are as follows:

y = 2000(11) = 22000

y = 2000(50) = 100000

y = 2000(150) = 300000

Multicollinearity refers to the degree of correlation among independent variables in a regression model.

In a multiple regression model, one predictor variable can be predicted linearly from the others using a high degree of accuracy when there is a phenomenon known as multicollinearity (also known as collinearity). In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the complete set of predictors predicts the outcome variable, but it could not provide accurate information about any particular predictor or which predictors are redundant in relation to others.

Stanley bought total 299 kilograms of rice.

To find the amount of rice in kilograms, bought by Stanley, we will perform multiplication and addition.

Weight of 1 bag = 13 kilograms

Weight of white rice = 16 × 13

Performing multiplication to calculate the weight

Weight of white rice = 208 kilograms

Weight of brown rice = 7 × 13

Performing multiplication to calculate the weight

Weight of white rice = 91 kilograms

Total amount of rice bought by Stanley = 208 + 91

Performing addition to calculate the weight

Total amount of rice bought by Stanley = 299 kilograms

Hence, Stanley bought total 299 kilograms of rice.

The equation can be written as 2.75x + 3.10 = 27.85

The number of miles in the taxi ride is 9

The taxi company was charged a pick-up fee of $3.10

It also charges $2.75 per mile

The total fare is $27.85

The equation can be written as

2.75x + 3.10 = 27.85

Collect the like terms to get the value of x

2.75x= 27.85 - 3.10

2.75x = 24.75

divide both sides by the coefficient of x which is 2.75

2.75x/2.75= 24.75/2.75

x= 9

Hence the number of miles in the taxi ride is 9

Step-by-step explanation:

The value of the partial sum of geometric sequence with terms a3 = 36 and a6 = 288 is given by 297. This is obtained by using the concept of partial sum of a geometric progression.

What is geometric progression?

Geometric progression is defined as a series of numbers having a fixed ratio between each term and its preceding term. It is also known as a geometric sequence or G.P., and is exemplified as a1, a2, a3, ….., an

Here, the first term is denoted by a1 and its common ratio is shown by r, which is calculated using the formula a2 by a1. The partial sum of a G.P. is given by a1 ( rn - 1 ) / ( r - 1 ), when r > 1 and a1 ( 1 - rn ) / ( 1 - r ), when r < 1

Calculation of the partial sum of the geometric sequence that satisfies the given conditions. a3 = 36, a6 = 288, n = 5

Given:

Value of a3 = 36

Value of a6 = 288

n = 5

a3 = ar2           — 1

a6 = ar5

Now, a6 / a3 = ar5 / ar2 = 288 / 36

r3 = 8

Taking cube root both sides, we get,

r = 2

Putting the value of r in equation 1,

a3 = a(2)2

36 = 4a

a = 9

As r > 1, using the formula for Sn as a(rn - 1) / (r - 1)

Sn = 9(2n - 1) / (2 - 1)

Sn = 9(2n - 1)

Using n = 5, we have,

Sn = 9[(2)5 - 1]

Sn = 9(32 - 1)

Sn = 9 × 33

Sn = 297

Hence, the value of the partial sum of a G.P. is 297

Using the z-distribution, it is found that mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.

We have a two-tailed test, with a significance value of α = 0.05, hence, using a z-distribution calculator, the critical value is given by:

|z| = 1.96 -> z < -1.96 or z > 1.96.

The test statistic is given as follows:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which:

For this problem, the parameters are given as follows:

[tex]\mu = 140, \sigma = 15, n = 36[/tex]

The lower bound of acception is found as X when z = -1.96, hence:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

-1.96 = (X - 140)/(15/6)

-1.96 = (X - 140)/(2.5)

X - 140 = -1.96 x 2.5

X = 135.1.

The upper bound of acception is found as X when z = 1.96, hence:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

1.96 = (X - 140)/(15/6)

1.96 = (X - 140)/(2.5)

X - 140 = 1.96 x 2.5

X = 144.9.

Hence:

Mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.

Answer:

a = 3 , b = - 2

Step-by-step explanation:

5a + b = 17 → (1)

3a + 2b = 5 → (2)

multiplying (1) by 2 and adding to (2) will eliminate b

10a + 2b = 34 → (3)

add (2) and (3) term by term to eliminate b

13a + 0 = 39

13a = 39 ( divide both sides by 13 )

a = 3

substitute a = 3 into either of the 2 equations and solve for b

substituting into (1)

5(3) + b = 17

15 - b = 17 ( subtract 15 from both sides )

- b = 2 ( multiply both sides by - 1 )

b = - 2

then solution is a = 3 , b = - 2
