Answer:

The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Total of megabytes of date used = x

Total monthly charges = y

x₁ = 50 Megabytes, x₂ = 100 Megabytes

y₁ = US$ 95, y₂ = US$ 120

2. Let's find out the best description of the steps to draw the graph and the slope.

Slope = (y₂ - y₁)/ (x ₂- x₁)

Slope = 120 - 95/ 100 - 50

Slope = 25/50 = 1/2 = 0.50

Remember that the coordinates of the points in the line are written this way:

(x, y) ⇒ (Total of megabytes of date used, Total monthly charges)

The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50

Answer:

The correct answer is that the probability of a randomly selected adult has an IQ less than 145 is 97.8%

Step-by-step explanation:

According to the graphic of a standard distribution attached, we have:

68.3% of the population will have an IQ +/- one time the standard deviation plus the mean. It means that 68.3% (Rounding to one decimal place) of the adults will have an IQ between 85 and 125.

95.5% of the population will have an IQ +/- two times the standard deviation plus the mean. It means that 95.5% (Rounding to one decimal place) of the adults will have an IQ between 65 and 145.

The remaining 4.5% of the adults will have either an IQ below 65 or above 145. In this case, we only want to know the percentage below 65 because the question is about the probability of an IQ less than 145. For calculating the percentage of adults that have an IQ less than 65, we use this fraction:

4.5%/2 = 2.3% (Rounding to one decimal)

and we add this percentage to 95.5:

Probability that a randomly selected adult has an IQ less than 145 = 95.5 + 2.3 = 97.8%

Answer: The profit is $3300

Step-by-step explanation:

The data we have is:

They charge $40 per hour.

In january, the charged for 200 hours.

The expenses are:

rent $4000

electricity $325

advertising $375

if we want to know the balance we must calculate:

The total expenses are: $4000 + $325 + $375 = $4700

The amount that they won is: $40*200 = $8000

Then the profit will be:

P = $40*200 - ($4000 + $325 + $375) = $8000 - $4700 = $3300

Answer:

65 bikes

Step-by-step explanation:

The store buys the bikes that they sell for $35, and they sell them for $85, so in order to find the actual amount of money earned from one sale, you have to subtract how much they sell the bikes for by how much they bought them for, so:

85 - 35 = 50

Then, you divide the $3250 by the 50:

3250 / 50 = 65

So now we know that the store must sell 65 bikes a month to break even.

[tex]0.035\times 10^{3}[/tex]

Step-by-step explanation:

Given: The value of 0.035

Now, as we know 0.035 has three decimal place which mean if we multiply by 1000 then we have the product 35 which is greater than 1 and less than 100, however if we multiply 0.035 by 10000 then the output will be greater than 100, which is invalid.

Lets us use hit and trail method.

[tex]0.035\times 1000 = 35 < 100\\\\0.035\times 10000= 350 >100[/tex]

Now lets put the value in expression

Answer: [tex]300\ Kg[/tex]

Step-by-step explanation:

Let be "x" the amount of butter (in kilograms) that the bakery used this month.

You need to divide the percentage by 100 in order to write it in decimal form. This is:

[tex]\frac{25}{100}=0.25[/tex]

According to the data given in the exercise, the total amount of butter they used last month is 240 kilograms.

Since 25% more butter was used this month than last month, you can write the folllowing equation:

[tex]x=240+(240 )(0.25)[/tex]

Evaluating, you get that the value of "x" is:

[tex]x=240+60\\\\x=300[/tex]

Therefore, the bakery used 300 kilograms of butter this month.

Final answer:

The bakery used 300 kg butter this month.

Explanation:

If a bakery used 25% more butter this month than last month and it used 240 kg of butter last month, then to calculate the amount of butter used this month, we need to add an additional 25% to the amount from last month. To find 25% of 240 kg, you multiply 240 kg by 0.25 (since 25% is the same as 0.25 when expressed as a decimal).

25% of 240 kg = 240 kg × 0.25 = 60 kg

Now, we add that 60 kg to the original 240 kg to find the total amount of butter used this month.

Total amount of butter used this month = 240 kg + 60 kg = 300 kg.

Therefore, the bakery used 300 kg of butter this month.

Answer:

5.603 g H2

Step-by-step explanation:

 M(NH3) = 14 + 1*3 = 17 g/mol

M(H2) = 2*1 = 2 g/mol

                        3H2 + N2 ----->   2NH3

from reaction   3 mol                  2 mol

from reaction    3*2 g                  2*17 g

given                    x g                   31.75 g

We can write a proportion.

(3*2)/x = 2*17/31.75

(2*17)x = (3*2)*31.75

x = (3*2)*31.75/(2*17) = 3*31.75/17 =5.603 g H2

Answer:

y= 12x+5 and It would be 10 days.

Step-by-step explanation:

Y= total

+5 = each rental

X= # of days

125= 12x+5; x=10

The equation to determine the cost of renting a chainsaw for x days is y = 12x + 5. For a cost of $125, one can rent the chainsaw for 10 days.

To write an equation for the number of dollars (y) that must be paid to rent a chainsaw for x days, take into account the daily rental fee and the one-time sharpening fee. The daily rental fee is $12, and there is an additional one-time sharpening fee of $5 for each rental. The total cost y is therefore the sum of the daily rental fees for x days and the sharpening fee.

The equation is:

y = 12x + 5

To find out how many days one can rent a chainsaw for a cost of $125, we can set y equal to $125 and solve for x:

125 = 12x + 5

Subtract 5 from both sides to get:

120 = 12x

Divide both sides by 12 to solve for x:

x = 10

Therefore, one can rent a chainsaw for 10 days at a cost of $125.

The dimension of the product is 2×2.

Step-by-step explanation:

The given problem is based on Matrices and it is a matrix multiplication  or Matrix product.

For any Two Matrix multiplication it is necessary, number of columns of matrix A  must be equal to  number of rows of matrix B.

Then only multiplication of matrix exist.

Then the product of multiplication i.e Matrix C will have the order number of rows of  Matrix A by number of columns of Matrix B

Let A be the first Matrix multiplied by matrix B

Matrix A is of order 2×3

Rows=2, column =3

Matrix B is of order 3×2

Rows=3, column =2

So here number of columns of matrix A  is equal to  number of rows of matrix B i.e 3

And the product order will be number of rows of Matrix A by number of columns of Matrix B .i.e 2×2

He will order 72 pairs of high tops

Explanation:

Given the store owner sells two pairs of running shoes for each pair of high tops

For every pair of high tops, he sells 2 pairs of running shoes

1 high top = 2 running shoes

He has planned to order 144 pairs of shoes

Therefore, 144 pair of running shoes = 144/2 = 72 pairs of high tops

Therefore, he will order 72 pairs of high tops
