A water tank already contains 55 gallons of water when Baxter begins to fill it. There is a crack in the tank and water begins to leak at a rate of 8 gallons per minute. Find the amount of water in the tank 6 minutes after Baxter begins filling the tank.

Answers

Answer:

Step-by-step explanation:

Therefore, the volume of the water in the tank 25 minutes after Baxter begins filling the tank is 255 gallons.

Step-by-step explanation:

Linear Equation; Ax+By=C

A linear equation to model this situation:

8x + 55 = C

Where;

8 is for the rate of gallons.

'X' is the minutes.

55 is the gallons of water the tank already contained.

8(25) + 55 = 255

Where;

8 is for the rate of gallons.

25 is the minutes.

55 is the gallons of water the tank already contained.

If f(x) = -2x2- x, what is f(2) and f(3)?

Answers


If f(x) = -2x^2 - x, what is f(2) and f(3)?

f(2) = -2x^2 - x
= -2(2)^2 - 2
= -4^2 - 2
= 16 - 2
f(2) = 14

f(3) = -2x^2 - 2
= -2(3)^2 - 2
= -6^2 - 2
= 36 - 2
f(3) = 34

The total population of Aiken County is 173,000 and there are approximately 23,000 students enrolled in Aiken County schools. What percentage of Aiken County residents are enrolled in Aiken County schools? Round your answer to the nearest tenth.

Answers

Answer:

Percentage = 13%

Step-by-step explanation:

Given the following data;

Total population = 173,000

Number of students = 23,000

To find the percentage;

[tex] Percentage = \frac {Number \; of \; students}{Total \; population} * 100 [/tex]

[tex] Percentage = \frac {23,000}{173,000} * 100 [/tex]

[tex] Percentage = \frac {23}{173} * 100 [/tex]

[tex] Percentage = 0.1330 * 100 [/tex]

Percentage = 13.3 ≈ 13%

Therefore, the percentage of Aiken County residents that are enrolled in Aiken County schools is 13%.

A production process is known to produce a particular item in such a way that 5 percent of these are defective. If two items are randomly selected as they come off the production line, what is the probability that both are defective (assuming that they are independent)

Answers

Answer:

0.0025 = 0.25% probability that both are defective

Step-by-step explanation:

For each item, there are only two possible outcomes. Either they are defective, or they are not. Items are independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

5 percent of these are defective.

This means that [tex]p = 0.05[/tex]

If two items are randomly selected as they come off the production line, what is the probability that both are defective

This is P(X = 2) when n = 2. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{2,2}.(0.05)^{2}.(0.95)^{0} = 0.0025[/tex]

0.0025 = 0.25% probability that both are defective

Find the Greatest Common Factor of the Numerator and Denominator

1. 1248
2. 2024
3. 1070

Answers

Answer: The answer is two.

Step-by-step explanation: start by making a tree diagram and dividing all three numbers by two. Each number needs to end in whole numbers with no decimals or fractions. 1248 will be 624, 2024 will be 1012, and 1070 will be 535. Then as you keep dividing the only numbers that match together is two on all three as you will get 3 and 13 added to 1248, 11 and 23 added to 2024, and 5 and 107 to 1070. The only numbers that match are two so your answer is two.

What is the completely factored form of this polynomial?
81x4 − 16y4

Answers

Answer:

( 9 x^ 2 + 4 y ^2 ) ( 3 x + 2 y ) ( 3 x − 2 y )

The completely factored form of the polynomial 81x^4 - 16y^4 is:

(3x + 2y)(3x - 2y)(9x^2 + 4y^2)(9x^2 - 4y^2)

Determining the completely factored form

Apply the difference of squares formula:

(9x^2)^2 - (4y^2)^2

Factor the difference of squares:

(9x^2 + 4y^2)(9x^2 - 4y^2)

Apply the difference of squares formula again:

(3x)^2 + (2y)^2

(3x)^2 - (2y)^2

Factor the difference of squares:

(3x + 2y)(3x - 2y)

Putting it all together, the completely factored form of the polynomial 81x^4 - 16y^4 is:

(3x + 2y)(3x - 2y)(9x^2 + 4y^2)(9x^2 - 4y^2)

Find the mid segment of GH

Answers

Answer:

B. 2

Step-by-step explanation:

Based on the Midsegment of a trapezoid theorem:

GH = (BC + FE)/2

9x - 3 = (19 + (5x + 1))/2) (substitution)

9x - 3 = (20 + 5x)/2

Cross multiply

2(9x - 3) = 20 + 5x

18x - 6 = 20 + 5x

Collect like terms

18x - 5x = 20 + 6

13x = 26

Divide both sides by 13

x = 26/13

x = 2

A statistics student has a mean score of 92 in the first 3 tests. Suppose there are a total of 4 tests and all of them have equal weight. You can also assume that there is no extra credit in the last test. What is the best possible final average this student can get

Answers

Answer:

The best possible final average this student can get is 94.

Step-by-step explanation:

The average score is given by the sum of the scores of all tests divided by the number of tests.

In this question:

First three tests: Mean score of 92, so total score of 92*3 = 276

Best possible score, with 4 tests:

In the first three, the total is 276. The best possible score is with a grade of 100 in the fourth test. The score will be:

[tex]M = \frac{276+100}{4} = \frac{376}{4} = 94[/tex]

The best possible final average this student can get is 94.

y = ⁴/3x - 7

Step-by-step explanation:

✔️First, find the slope (m):

Slope (m) = ∆y/∆x = 4/3

m = ⁴/3

✔️Determine the y-intercept (b):

The y-axis is intercepted by the line at y = -7, therefore the y-intercept (b) would be -7.

b = -7

✔️Write the equation:

Substitute the value of m = ⁴/3 and b = -7 into y = mx + b (slope-intercept form equation).

y = ⁴/3x + (-7)

y = ⁴/3x - 7
