Machine machine with 140 gallon capacity needs to be filled with water/glycol mixture. Someone has already pump 50 gallons of 60% glycol blend into the machine. How much more glycol must you add an order to get a 50% concentration?

Answers

Answer:

40 gal

Step-by-step explanation:

The capacity of the machine is 140 gallons, and it must be filled.

In a 50% glycol solution, the amount of glycol in 140 gallons of solution is

50% * 140 gallons = 70 gallons.

Once the machine is full with 140 gallons of 50% glycol solution, it will have 70 gallons of glycol.

The machine now has 50 gallons of 60% glycol solution.

60% * 50 gallons = 30 gallons

The machine has now 30 gallons of glycol.

70 gal - 30 gal = 40 gal

You must add another 40 gallons of glycol.

Tammy opened a credit card with a 19% simple interest rate to purchase a $879 laptop. If she pays off the laptop in 18 months, how much will she have paid in total?

Answers

Answer:

$1146.216

Step-by-step explanation:

Given data

Principal= $879

Rate= 19%

Time = 18months= 1.6 years

The expression for the simple interest is

A=P(1+rt)

substitute

A=879(1+0.19*1.6)

A= 897(1+0.304)

A= 879*(1.304)

A= $1146.216

Hence the amount to be paid is $1146.216

Answer:

3. 37

4. 59

5. 79

Step-by-step explanation:

All the angles of the triangle add up to 180°

3. 180-(31+112) = 37°

4. (4x-18)+(8x+7)+(5x+4) = 180

   17x-7 = 180

17x = 187

x =11

we have found the x now we need to input it to find m∠z

5x+4

=5×11+4

=59°

5. A straight angle is 180° so if the outside angle is 129 the inside one will be 51°

(2x-3)+(x+9)+51 = 180

3x+57 = 180

3x = 123

x = 41

Now we need to find m∠L

2x-3

= 2×41-3

= 79°

You estimate that there are 60 marbles in a jar.The actual amount is 54 marbles. Find the percent error.Round to the nearest tenth of a percent if necessary

Answers

Answer:

the percent error is 10%

Step-by-step explanation:

Given that

The estimate value of the marbles is 60

And, the actual amount is 54 marbles

We need to find out the percent error

As we know that

Percent error = (Estimated - actual)  ÷ (Estimated) × 100

= (60 - 54) ÷ 60 × 100

= 10%

Hence, the percent error is 10%

We simply applied the above formula

can someone help me with this? it’s linear regression and i forgot how to do it

Answers

I'll do problem 1 to get you started. The completed filled out table is shown below in the attached image.

We have x as the input and y as the output. The observed value is the second column, and this is the actual y value we're aiming for. The predicted value is an estimation based on what the linear regression line says. The residual is the error or gap between the observed and predicted.

With that in mind, let's fill out the table. In the first row, we have x = 5 pair up with y = 3. The predicted y value is y = 0.5x = 0.5*5 = 2.5, meaning we'll write "2.5" without quotes in the first blank space of that first row. The residual is

e = error or residual

e = (observed y value) - (predicted y value)

e = (3) - (2.5)

e = 0.5

A positive residual means that the observed y value is larger than the predicted one. The predicted y value is an under-estimate. We'll write "0.5" without quotes underneath "residual" in the first row.

-------------------

We'll repeat the same steps for row 2

This time we have x = 10 lead to a predicted y value of y = 0.5*x = 0.5*10 = 5

The residual is

e = (observed) - (predicted) = (4) - (5) = -1

The negative residual tells us the observed value is smaller than the predicted one. The predicted value is an over-estimate.

--------------------

For row 3, we have the input x = 15 lead to a predicted y value of y = 7.5 since y = 0.5*x = 0.5*15 = 7.5

The residual is therefore: e = (observed y) - (predicted y) = (9) - (7.5) = 1.5

The nice thing about how this table is set up, is that the observed y values are listed first, then the predicted y values next. This may help you remember how the order of subtraction will go.

The steps for rows 4 through 6 are the same as mentioned earlier, so there's nothing new here.

The completed table for problem 1 is shown below in the attached image.

A bag contains 22 coins consisting of quarters and nickels. The total value of the coins is $3.90. How many nickels are in the bag? *

Answers

Answer:

8 Nickels

Step-by-step explanation:

Since a Nickel is worth 5 cents ($0.05)

And a Quarter is worth 25 ($0.25)

and theres 22 coins

8 of those coins would be nickels which would mean we add 8 nickels up

8 x 0.05 = 0.4

then we add the quarters up

14 x 0.25 = 3.5

3.5 + 0.4 = $3.90
