Answer:

The total number of pencils that Mr. Moretti gives to his is 162.

Step-by-step explanation:

He puts 3 mechanincal pencils in each bag.

In each bag, there is also twice as many regular pencils, that is, 3*2 = 6 regular pencils.

So in each bag, 3 + 6 = 9 pencils.

What is the total number of pencils that Mr. Moretti gives to his students if he puts 3 mechanical pencils in each bag?

18 students, and each gets 9 pencils.

18*9 = 162

The total number of pencils that Mr. Moretti gives to his is 162.

Answer:

162 pencils

Answer:

a will be the correct answer bro be sure

The Regression equation best fits these data is ŷ = -0.58939x + 12.52235

We have the table as from which can be calculated as

Sum of X = 2

Sum of Y = 99

Mean X = 0.25

Mean Y = 12.375

Sum of squares (S[tex]S_x[/tex]) = 89.5

Sum of products (SP) = -52.75

As, Regression Equation

ŷ = b x + a

where b = SP/S[tex]S_x[/tex]

b = -52.75/89.5

b = -0.58939

and, a = MY - b MX

a = 12.38 - (-0.59)(0.25)

a = 12.52235

So, the required equation is ŷ = -0.58939x + 12.52235

Answer:

13:7

Step-by-step explanation:

We see that the ratio from women:children is 13:4.

Therefore, the number of women is 13.

In the ratio comparing men to children we see that it is 7:3.

Therefore, the number of men is 7.

Now we need to compare the number of women to the number of men which is 13:7.

Answer:

$35.20

Step-by-step explanation:

Given that the profit of 24% was made on $34.10,

And Profit = Selling price - cost price,

Where profit is 24%, and selling price is $34.10, cost price = ?

Then, to find the cost price (z):

Assume the cost price be a 100% and the selling price of $34.10 be 124%

Hence, we have

$34.10 = 124%

z = 100%

Substitue

=> z / 34.10 = 100% / 124 %

=> 124z = 34.10 (100)

124z = 3410

Divide both sides by the coefficient of z which is 124

z = $27.50

Therefore, to find the selling price for a profit of 28%

We have 28% of 27.5 = 7.70

With equation of Profit = Selling price - cost price

We have 7.70 = Selling price - 27.50

Removing 7.7 from both sides

We have, Selling price = 27.50 + 7.70

=> Selling price = $35.20

Hence, the selling prices for a profit of 28% is $35.20

Answer:

When you multiply the number by its reciprocal the numerator of the one becomes the denominator of the other and is equals to 1 .

Answer:

1 3/8

Step-by-step explanation:

Since 11 is over 8 that means you already have a whole number so you just add the 3 and you get 1 3/8

To check just in case you just multiply the whole number and denominator and then add the numerator.

Answer:

A) PB M(b, m), we have;

b = 1

b = 2

b = 3

B) E(B) = 1.7

C) No they are not independent

Step-by-step explanation:

A) We are told that a shipment can be in 1 box for a small order, 2 boxes for a medium order, 3 boxes for a large order. Thus;

For PB M(b, m), we have;

b = 1

b = 2

b = 3

B) Factory Q is 60 miles from the company. Thus, under factory Q in the table, m = 60

Factory R is 180 miles from the company. Thus under factory R in the table, m = 180

Now;

P_B (b) for b = 1 which is small order is;

P_B (b) = 0.3 + 0.2 = 0.5

P_B (b) for b = 2 which is medium order is;

P_B (b) = 0.1 + 0.2 = 0.3

P_B (b) for b = 3 which is large order is;

P_B (b) = 0.1 + 0.1 = 0.2

Thus;

E(B) = Σb•P_B (b) = (1 × 0.5) + (2 × 0.3) + (3 × 0.2)

E(B) = 0.5 + 0.6 + 0.6

E(B) = 1.7

C) No, they are not independent. This is because from the table we are given, P_B,M at b = 1 and m = 60 is given as 0.3.

Whereas, for B and M to be independent, P_B,M at b = 1 and m = 60 has to be equal to (P_M(m) under m = 0.3) multiplied by P_B(b) for b = 1.

Instead what we have is P_M(m) under m = 0.3 as; 0.3 + 0.1 + 0.1 = 0.5. Which means (P_M(m) under m = 0.3) multiplied by P_B(b) for b = 1 gives;

0.5 × 0.5 = 0.25 which is not equal to P_B,M = 0.3 at b = 1 and m = 60

[tex] = 24[/tex]

[tex]a = \frac{1}{2} (b1 + b2)h[/tex]

Answer:

245 ft sq

Step-by-step explanation:

Find the are of the triangle and the square seperatly.

Area of a square is A = s * s

A = 14  * 14 = 196 ft sq

Focusing on the triangle, the dotted line is the same length as the bottom of the square. 14 ft

Area of a triangle is A = 1/2 * b * h

A = 1/2 * 14 * 7

A = 7 * 7

A = 49 ft sq

So, 196 + 49 = 245
