Answer:

$104.51

Step-by-step explanation:

No.of people = 7

How much each person paid = $14.93

How much is the total bill = $14.93 x 7

                                          = $104.51

I was bored so I added the steps lol

Answer: See explanation

Step-by-step explanation:

A nearby store sells a 20-pack of AA batteries for $12.49. Therefore, the cost of 1 pack will be:

= $12.49 / 20

= $0.6245

The store also sells a 12-pack of the same batteries for $7.20. The cost per pack will be:

= $7.20 / 12

= $0.6

Therefore, it will be less expensive for Mr. Franklin to purchase the batteries in 12 packs.

The difference between the costs of one battery from each pack will be:

= $0.6245 - $0.60

= $0.0245

Answer:

μ = 0.4

Standard deviation σ = 0.0512 (Approx)

Step-by-step explanation:

Given:

Sample size n1 = 100

Sample size n2 = 200

Proportion p1 = 0.7

Proportion p2 = 0.3

Find:

Standard deviation σ

Computation:

μ = p2 - p1

μ = 0.7 - 0.3

μ = 0.4

Standard deviation σ = √p1(1-p1)/n1 + p2(1-p2)/n2

Standard deviation σ = √0.7(1-0.7)/100 + 0.3(1-0.3)/400

Standard deviation σ = √0.0021 + 0.000525

Standard deviation σ = √0.002625

Standard deviation σ = 0.0512 (Approx)

Answer:

x = - 7, x = 3

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

x² + 4x - 21 = 0

Consider the factors of - 21 which sum to give the coefficient of the x- term (+ 4)

The factors are + 7 and - 3, since

7 × - 3 = - 21 and 7 - 3 = + 4, then

x² + 4x - 21 = 0

(x + 7)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 3 = 0 ⇒ x = 3

Answer:

Step-by-step explanation:

Lands on C on 8 out of 30 times = 4/15= .26666 times

we expected to land on C using theoretical probability 1/5 =.2 times

for 1,000 times it will be expect to land on C, 200 times because,

1*200 = 200 C  : 5*200 =1,000 spins

we do not expected to land on C exactly 200 times yet we expected  something close to that 200 number.

Answer:

G. 60m

H. 7.5cm

Step-by-step explanation:

0.8 = [tex]\frac{8}{10}[/tex]

Perimeter of figure = (12 + 10 + 16 + 10) × [tex]\frac{10}{8}[/tex]

                                = 48 × [tex]\frac{10}{8}[/tex]

                                = 60m

1.5 feet --- 0.75cm

15 feet --- [tex]\frac{15}{1.5}[/tex] × 0.75cm = 7.5cm

Answer:

Step-by-step explanation:

BC= 9.6

CD=8

BA=8

y = - [tex]\frac{1}{2}[/tex] x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y + 4 = - [tex]\frac{1}{2}[/tex] (x - 2) ← distribute

y + 4 = - [tex]\frac{1}{2}[/tex] x + 1 ( subtract 4 from both sides )

y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form

The probability that a person has never flown given that he/she is a person who is afraid of flying is 0.875

The table of values is given as

                            Flown Before      Not Flown Before  Totals

Afraid to Fly                   0.01                     0.07                 0.08

Not Afraid to Fly           0.79                      0.13                  0.92

Totals                             0.8                        0.2                      1

The probability that a person has never flown given that he/she is a person who is afraid of flying is calculated as

P = P(Afraid of flying and Never flown before)/P(Never flown before)

This gives

P = 0.07/0.08

Evaluate

P = 0.875

Hence, the probability that a person has never flown given that he/she is a person who is afraid of flying is 0.875

Answer:

A sandwich is $3.50 and the price of a drink is $2.50

Step-by-step explanation:

Create a system of equations where s is the price of a sandwich and d is the price of a drink:

9s + 5d = 44

15s + 7d = 70

Solve by elimination by multiplying the top equation by 7 and the bottom equation by -5, then adding them together:

63s + 35d = 308

-75s - 35d = -350

Add them together:

-12s = -42

s = 3.5

Then, plug in 3.5 as s into one of the equations to solve for d:

9s + 5d = 44

9(3.5) + 5d = 44

31.5 + 5d = 44

5d = 12.5

d = 2.5

So, a sandwich is $3.50 and the price of a drink is $2.50

A sandwich is $3.50 and the price of a drink is $2.50

Answer:

72 dogs

Step-by-step explanation:

3 dogs/2 cats = x dogs/48 cats

Cross Multiply

3/2 x x/48

2x=144

x=72

Answer:

72 dogs

Step-by-step explanation:

First turn 3:2 into a fraction:

3/2

Then you can make the equation a proportion question, which is much eaiser to handle.

3/2=x/48  (I recommend writing this out so it will be easier to see)

Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.

Multiply 2 by x, which becomes 2x.

Multiply 3 by 48, which is 144

This becomes... 2x=144

You then solve with equation by dividing 144/2 and getting 72.

Meaning x=72 dogs
