Answer: If I did it correctly- The answer should be 3

I'm not fully sure though

Answer: The median is the middle value when the values in the data set are ordered from least to greatest. {0,2,3,4,7,7,8,12}. Usually when there are 6 numbers in a set, it gets split between the 6th and 7th number, but since it's two 7s, the answer is 7.

Which function below has the smallest slope? f(x)

f(x) = 5x − 4

g(x)

graph going through (0, 1) and (2, 5)

h(x)

x h(x)

1 14

4 15

7 16

F(x) = 5x - 4.....slope is 5

g(x) : (0,1)(2,5)

slope = (5 - 1) / (2 - 0) = 4/2 = 2 .....slope is 2

h(x) : (1,14)(4,15)

slope = (15 - 14) / (4 - 1) = 1/3..slope = 1/3

so the smallest slope would be : h(x) with a slope of 1/3

g(x) : (0,1)(2,5)

slope = (5 - 1) / (2 - 0) = 4/2 = 2 .....slope is 2

h(x) : (1,14)(4,15)

slope = (15 - 14) / (4 - 1) = 1/3..slope = 1/3

so the smallest slope would be : h(x) with a slope of 1/3

Answer: h(x)

Which of the following is a linear equation: (a)x2-y2=1 (b)y=3/4-x/2 (c)x2+y2=1 (d)y=3/4+2/x

The format you wrote them in shows that all of them are linear equations. Im going to assume that some of the are supposed to be exponent.

Melanie spent four hours babysitting. She charges $16 upfront and then an additional charge per hour. The total amount she earned can be represented by the expression $4x +$16. What expression represents the amount she earns each hour?

Answer:

$4

Step-by-step explanation:

She charges $16 upfront

$4x + $16

The $16 charges upfront is the $16 in bold.

The $4x is the amount she charges depending on the hours.

The number of hours is x. The amount she charges per hour is $4.

Answer: $4

Write the equation 5x + y = 4 in slope-intercept form

Y = mx + b

5x + y = 4

y = -5x + 4

5x + y = 4

y = -5x + 4

Write a word problem whose solution is -70=70

Well, -70 doesnt equal 70. But you could do something like this: Mike swam 70 m below the surface of water. After his swim, he hiked up a mountain 70 m high. Sorry if this doesnt work.. hope it helps though!

You can't really make a word problem for that; at least, that's what I think. If I'm wrong, I'm sorry.

The U.S. Census Bureau claims that 26% of all U.S. businesses are owned by women. A researcher in Denver believes that the percent is higher there. A consulting firm surveys a random sample of 410 businesses in the Denver area and finds that 115 of them have female owners. What is the P value for testing the hypotheses H0:p=0.26 versus Ha:p>0.26 ?a) 0.946b) 0.172c) 0.344

Answer:

b) 0.172

Step-by-step explanation:

We have a large sample size n = 410 and .

For testing the hypotheses vs 0.26" alt="H_{1}: p > 0.26" align="absmiddle" class="latex-formula"> (upper-tail alternative) the test statistic is given by and the observed value is . The p-value is computed as P(Z > 0.924) = 0.1777 where the random variable Z comes from a standard normal distribution.

The cumulative relative frequency of the number of refrigerators sold per day the Appliance store is Number of units Cumulative relative frequency

0 0.2

1 0.4

2 0.5

3 0.75

4 1.00

What is the relative frequency of sales of 2 units per day?

Answer: 0.1

Step-by-step explanation:

We know that the to find the cumulative relative frequency we add all of the previous relative frequencies to the corresponding relative frequency .

Given Table :

Number of units ( per day) Cumulative relative frequency

0 0.2

1 0.4

2 0.5

3 0.75

4 1.00

The Cumulative relative frequency corresponds to 2 units per day = 0.5

The Cumulative relative frequency corresponds to previous row (1 units per day) = 0.4

Now, the relative frequency of sales of 2 units per day = 0.5-0.4=0.1

Hence, the relative frequency of sales of 2 units per day =0.1

Find two mixed numbers so that the sum is 8 4/8 and the difference is 2 2/8

Using a system of equations, it is found that the numbers with the desired sum and difference are given by:

What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are x and y. Initially applying the conversion from mixed to fraction, the system is:

Since :

Then y is given by:

Now we apply the conversion to mixed numbers, as 27 divided by 8 has quotient 3 and remainder 4, and 9 divided by 8 has quotient and remainder 1, hence:
