What is the volume of the container below? ​

Answer:

C. x = 3, y = -6 is the answer.

Step-by-step explanation:

1. Isolate x for x = 2y = 15 -> x = 15 + 2y

2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]

3. Simplify -> [30 + 8y = -18)

4. Isolate y for 30 + 8y = -18 -> y = -6

5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)

So, x = 3 and y = -6 are the solutions to this system of equations.

Answer:

1/4, or 0.25 inches

Step-by-step explanation:

You count the dots. The number of dots tell you how many of each length of string she used.

You first find the column with the most dots, and then you find the column with the least. Then you just subtract them, the number of inches it displays on the bottom, 12 1/2 - 12 1/4, which is 1/4. I did this in my head and you can use a calculator if you want.

Thanks for the points, and have a blessed day. Hope this helps.

Answer:

The recycling incentive was effective at  5% significance level.

Step-by-step explanation:

The null and alternative hypothesis are

H0 u1≤  u2 against the claim Ha: u1> u2

or

H0 ud=0 against the claim  Ha: ud > 0

The significance level is ∝=0.05

Data given

d`= 3.78

sd= 1.33

n= 10

The test statistic is

t= d`/ sd/ √n

t= 3.78/1.33/√10

t= 9.3889

The critical region for  ∝=0.05 and df.= (n-1)= 9 is t> 1.833

Since the calculated value of t lies in the critical region it is concluded that  new recycling incentive would increase the number of people that seperate their garbage from recyclable items.

H0 is rejected and Ha is accepted.

Answer:

The correct answer is B. George’s computer is expected to have a value of $25 greater.

Step-by-step explanation:

Since Chelsea bought a computer on Monday for $ 1,300, and its value is predicted to decrease by $ 250 per year, while her brother George also bought a computer on Monday, and the function g (x) = 1,100 - 175x predicts how the value of his computer is expected to change after x years, to determine whose computer is expected to have a greater value when it is 3 years old, and how much greater will it be, the following calculation must be performed:

Chelsea:

1,300 - (250 x 3) = X

1,300 - 750 = X

550 = X

George:

1,100 - (175 x 3) = X

1,100 - 525 = X

575 = X

Therefore, George’s computer is expected to have a value of $ 25 greater.

Answer: f(3)=g(3)

Step-by-step explanation:

The graphs intersect at x = 3.

The statement "f(6) = g(3)" is true.The correct option is A.

A graph is a structure that amounts to a set of items where some pairs of objects are in some manner "related" in discrete mathematics, more specifically in graph theory.

From the graph, we can see that the value of f(6) is 2, and the value of g(3) is also 2.

The statement "f(3) = g(3)" may or may not be true, as we do not know the values of f(3) and g(3) from the graph.

The statement "f(3) = g(6)" is not true, as the value of f(3) on the graph is -2, and the value of g(6) is 4.

The statement "f(6) = g(6)" is also not true, as the value of f(6) on the graph is 2, and the value of g(6) is 4.

Answer:

15.38%

Step-by-step explanation:

There are 4 7's in a deck of 52 cards.

There are 4 Aces in a deck of 52 cards.

4+4 = 8

8/52, or 15.38%

=================================================

Explanation:

There are four cards labeled "7", and four cards that are aces. We have 4+4 = 8 cards that we want to find. This is out of 52 total.

The probability we're after is 8/52 = (4*2)/(4*13) = 2/13

2/13 = 0.1538 = 15.38% approximately

Answer: p-value ≈ 0.08

Step-by-step explanation:

The approximate p-value of the test is 0.0136 as per the data given in question.

The p value is a number calculated from a statistical test that describes the likelihood of finding a specific set of observations if the null hypothesis is true.

To find the approximate p-value of the test, we need to compare the sample proportion p^ to the hypothesized proportion p0 = 10% under the null hypothesis H0:p=10% vs. Ha:p>10%.

Since the sample size n is large (n = 150) and the null hypothesis assumes a normal distribution.

We can use the normal approximation to the binomial distribution. Under the null hypothesis, the test statistic z is given by:

z = (p^ - p0) / sqrt(p0 * (1 - p0) / n)

Plugging in the values, we get:

z = (0.14 - 0.1) / sqrt(0.1 * 0.9 / 150)

z = 2.22

The approximate p-value for this one-tailed test can be found by looking up the area to the right of z = 2.22 under the standard normal distribution.

Using a standard normal distribution table or calculator, we find that the area to the right of z = 2.22 is approximately 0.0136.

Therefore, the approximate p-value of the test is 0.0136. This means that if the true proportion of left-handed art students at the university is 10%, there is approximately a 1.36% chance of getting a sample proportion of 14% or higher by random chance alone.

Answer:

n + 45

Step-by-step explanation:

The question is asking to write an algebraic expression for the sum of a number and 45. We know we are adding a number to 45. So we use addition. But, we don't which number we are adding to 45. So we just use a variable. I used "n", but use whatever letter you want ( x, y, z, etc). I recomend using the same variable that your intrcuctor uses.
