Step-by-step explanation:

is the six supposed to be included as individual number

2, 2.4, 2.8, 3.2, 3.6, 4, 4.4, 4.8, 5.2, 5.6, 6

5 number summary=2, 2.8, 4, 5.2, 6

IQR=5.2-2.8=2.4

mean=4

median=4

max=6

min=2.8

Since that didn't give me any answers I will assume 6 is a typo.

2, 2.4, 2.8, 3.2, 3.6, 4, 4.4, 4.8, 5.2, 5.6

5 number=2, 2.6, 3.8, 5, 5.6

IQR=2.4

mean=3.8

min=2

max=5.6

median=3.8

The data set does not correlate with any written claims so I think I interpreted the data wrong or it is written wrong time message details and I will try again

What is the quotient if <br> 1/3 of 10 is divided by 1/7 of 8/12? Reduce if possible.

MrMuchimi

Answer:

1/35

Step-by-step explanation:

1/3 of 10 (of means multiply)

1/3 times 10 is 10/3

1/7 of 8/12=2/21

2/21 divided by 10/3

use keep change flip

2/21 divided by 10/3 equals 2/21* 3/10

1/35 is the answer

What is 347,168 round to then thoudands

Finger [1]

Answer:

347,168 rounded to the nearest ten thousands would be 350,000.

Step-by-step explanation:

When rounding to the nearest ten thousands, you rely on the thousands place value to indicate whether to round up or down. 5 or higher give it a shove, 4 or less let it rest. 7 is in the thousands place meaning we round up. 4 is in the ten thousands place meaning it becomes 5. 347,168 rounded to the nearest ten thousands would be 350,000.

ivann1987 [24]

Answer:

x= negitive 6/8

Ok think about it 1/4 plus 1/2 is 3/4

so how do i go to negitives?

you double the amount of it and then minus it

because 3/4- 3/4 would be zero

so you have to double it to get that answer

You are considering developing a regression equation relating a dependent variable to two independent variables. One of the vari

lys-0071 [83]

Answer:

Step-by-step explanation:

a. How many dummy variables are needed to represent the categorical variable?

We need 1 less dummy variable than outcomes for the categorical variable.

categorical variable has 2 outcomes

So, we need 2-1 = 1 dummy variable.

Answer: 1

Note: If our categorical variable had 5 outcomes, we would need 5-1 = 4 dummy variables.

b. Write the multiple regression equation relating the dependent variable to the independent variables.

Note: Depending your your professor, this can be written one of the following ways...

yhat = a + b1 x1 + bx2

yhat = b0 + b1 x1 + b2 x2

yhat = beta0hat + beta1hat x1 + betahat2 x2

where x1 is the ratio variable

and x2 is the dummy variable

c. Interpret the meaning of the coefficients in the regression equation.

b0 = the predicted value of y when x1 and x2 both equal 0.

b1 = the change in y when x1 increases by 1 unit holding x2 constant.

b2 = the predicted difference in y between the two possible outcomes of the categorical variable holding x1 constant.
