How many 1-yard-square tiles would it take to cover this rectangle? Dimensions are in yards.

Answer:

A.)

Lower Value = 295

Upper Value = 485

B.)

Lower Value = 200

Upper Value = 580

C.)

Lower Value = 105

Upper Value = 675

Step-by-step explanation:

Given that mean (M) = 390

Standard deviation (σ) = 95

Lower Value = mean value - number of standard deviations specified

Upper Value = mean value + number of standard deviations specified

a. Μ ± 1σ of the observations lie between what two values?

Lower Value = 390 - 1(95) = 295

Upper Value = 390 + 1(95) = 485

b. Μ ± 2σ of the observations lie between what two values?

Lower Value = 390 - 2(95) = 200

Upper Value = 390 + 2(95) = 580

c. Μ ± 3σ of the observations lie between what two values?

Lower Value = 390 - 3(95) = 105

Upper Value = 390 + 3(95) = 675

Answer:

a.It is a good fit because the same number of data points are on each side of the line.

c.The line shows a positive correlation.

e.The rate of change can be represented by the slope of the trend line.

Step-by-step explanation:

Answer: -It is a good fit because the same number of data points are on each side of the line.

- The line shows a positive correlation.

-The rate of change can be represented by the slope of the trend line.

Step-by-step explanation:

Answer:

y=3x-3

Step-by-step explanation:

the y(intercept)= -3 because the point is at -3 on the y-axis. from there the line goes up 3 and over 1. the slope would be 3.

All together the equation of the line is:

Y=3x-3

Answer:

k = $0.50

Step-by-step explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..

12.50/25 = 0.5/1

17.50/35 = 0.5/1

hopefully this can help you in some way! sorry if it doesn't

Answer:

Bedroom = x^2 ft^2

Closet = 25 ft^2

Bathroom = 6x ft^2

Answer:

2 apples = .24 kilograms

12 apples = 1.44 kilograms

Step-by-step explanation:

If 5 apples all weigh The same amount. Let x represent one apples weight

5x = 0.60

divide by 5

one apple weighs .12 kilograms

then multiply by the number of apples. So 2 apples is .24

and 12 apples is 1.44

Given :

A group of three friends order a combo meal which includes case slices of pizza and a drink each drink is priced at $2.50 .

Total bill, T = $31.50 .

To Find :

The cost of a slice of pizza.

Solution :

Price of 3 drinks, P = 3×2.50 = $7.5  .

Now,

[tex]\text{Price of each slice }=\dfrac{\text{Total price - Price of drinks}}{\text{Number of slice}}\\\\p = \$(\dfrac{31.50-7.50}{3})\\\\p = \$8[/tex]

Therefore, price of each slice of pizza is $8.

Hence, this is the required solution.

you need 10 8' planks of wood because 15x3= 45+9x4= 77, then 77÷8= 9.625, but you can't get .625 of a plank, so 10. hope you get a good grade!

Answer:

Step-by-step explanation:

Change fractions to have the same denominator or change them all to a decimal.  Then add.

Decimal method:

1 and 15/100 is equal to 1.15

1/50 is equal to 0.02

The final term is already a decimal

Add.  1.15 + 0.02 + 1.175 = 2.345

Solve for k:

k = 4 (2 − 3p)/p + 4

Answer:

k =  4(2 - 3p)/(p + 4).

Step-by-step explanation:

p(k + 12) = 8 – 4k

pk + 12p = 8 - 4k

pk + 4k = 8 - 12p

k(p + 4) = 8 - 12p

k = (8 - 12p)/(p + 4)

k = 4(2 - 3p)/(p + 4).

Answer:

a line

Step-by-step explanation:

a linear equation is an equation that may additionally be put in the structure where are the variables, and are the coefficients, which are often real numbers. The coefficients may also be considered as parameters of the equation, and may also be arbitrary expressions, furnished they do no longer include any of the variables.
