The harbormaster decides how many trips the ferry needs to
make for 37 cars. The ferry can carry 8 cars at a time. How many trips does the ferry need to make so that all cars can cross the harbor?

Note: The only way to solve this problem is by adjusting the fees to $3.50 and $7.50.

Answer:

1300 children attended the basketball game

Step-by-step explanation:

System of Equations

Let's call:

x = number of children attending the basketball game

y = number of adults attending the basketball game

On a certain night, 1500 people enter the game, thus:

x + y = 1500           [1]

Since each admission fee for children cost $3.50 and $7.50 for adults and it was collected $6050, thus:

3.50x + 7.50y = 6050            [2]

From [1]:

y = 1500 - x

Substituting in [2]:

3.50x + 7.50(1500 - x) = 6050

Operating:

3.50x +  11250 - 7.50 = 6050

-4x = 6050 - 11250

Solving:

x = 1300

Answer:

f(-8) = 54

Step-by-step explanation:

To start, replace x in the equation with -8. This will give you f(-8) = 6(1 - (-8)) which can be simplified to f(-8) = 6(1 + 8). Apply the distributive property on the right side of the equation to get f(-8) = 6 + 48. When simplified, you get f(-8) = 54.

Answer:

Answer:

x = 7 and 36/7 = 5.14285714286

Step-by-step explanation:

add 3 to both sides of ( x - 3 ) = 4

x = 7

36/7 = 5.14285714286

Answer:

7 ten dollar bills and 5 twenty dollar bills

Step-by-step explanation

He recieved 5 bills of $20 and 7 bills of $10.

We have the following statement Angelo cashed a check for $170, the bank teller gave him 12 bills, some $20 bills and the rest $10 bills

We can write -

20x + 10y = 170

x + y = 12

So, we can write -

y = 12 - x

We can write -

20x + 10(12 - x) = 170

20x + 120 - 10x = 170

10x = 50

x = 5

then -

y = 7

Therefore, he recieved 5 bills of $20 and 7 bills of $10.

Answer:

27

Step-by-step explanation:

9.00 divided by 4 = 2.25

2.25 x 12 = 27

Answer:

$27

Step-by-step explanation:

First, you would take 12(amount of pizzas the question is asking) divided by 4(amount of pizzas) and get 3

Then you multiply $9.00(the delivery fee for 4 pizzas) by 3(how much pizzas the question is asking divided by 4) and get $27

12 divided by 4 = 3

3 times $9.00 = $27

Answer:

This known value does not match the measured value at the 95% confidence level.

The 95% confidence interval for value is calculated as 42.92 to 43.78%,

Step-by-step explanation:

The complete question is:

Police have a hit-and-run case and need to identify the brand of red auto paint. The percentage of iron oxide, which gives paint its red color, was determined to be 43.35 ± 0.33% by one method of analysis using five measurements. The color reference provide by the automotive manufacture is 44.21%. What can you conclude about whether the sample matches the reference at a 95% confidence level?

Student's t test is used to compare the two values .

Here n=5

Degrees of freedom =ν= n-1= 5-1=4

The value from t- table for 4 d.f at 95 % confidence interval is 2.776

The test statistic is

x`± t ∝/2(v). S/√n

43.35 ± (2.776)(0.33)/√5

= 43.35 ± 0.43

= 43.78, 42.92

Here the 95% confidence interval for μ calculated is 42.92 to 43.78%, where as color reference provided by the automotive manufacture is 44.21%.

This known value does not match the measured value at the 95% confidence level.

Answer:

1.08 is the constant of proportionality.

Step-by-step explanation:

The constant value (often written k) relating amounts that rise or fall uniformly together.

It is the ratio of the amounts y and x:

k = y/x

Put another way: y = kx

Example: you are paid $20 an hour

The constant of proportionality is 20 because: Pay = 20 × Hours worked
