Answer:

Here are the answers. Hope this helps you!

Step-by-step explanation:

11/12*9/22 = rational (as the solution is 33/88 which is in p/q form with q not equal to 0 and p and q as integers.)

√5 *8 = 8√5 = irrational

3 + √17 = irrational (sum of a rational and irrational number is always irrational)

√3*√12 = √36 = 6= rational number

π - 2π = -π = irrational (since π is irrational)

-3/8 + 3/5 = -15+24/40 = 9/40 = rational

√6/2 - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational (in this case difference is irrational and the product is clearly irrational as well).

six clowns perform three acts in a circus. the clowns appear two at a time. Jack, Marty, and Orville are paired with Kelly, Lesl

ladessa [460]

Answer:

The pair that performs second are Orville and Nancy.

Step-by-step explanation:

Since Jack and Leslie are partners and that they appear before Kelly, it is safe to assume that this pair may come first beforehand in which Orville also comes on before Kelly. Nancy also appears before Leslie and since each pair has a female and a male, it is safe to assume that Orville and Nancy perform second while Jack and Leslie perform first and Kelly and Marty perform last.

In recent years the mean number of miles driven per year by residents of a particular state was 11,568. A researcher wishes to t

aleksandrvk [35]

Answer:

The degrees of freedom are given by:

$df =n-1= 62 -1=61$

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be $t_{\alpha/2}= \pm 2.00$

And the rejection region would be $|t_{calc}| >2.00$

Step-by-step explanation:

Data given and notation

$\bar X=10822$ represent the sample mean

$s=1741$ represent the sample standard deviation

$n=62$ sample size

$\mu_o =11568$ represent the value that we want to test

$\alpha=0.05$ represent the significance level for the hypothesis test.

z would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the true mean differs from 11568, the system of hypothesis would be:

Null hypothesis: $\mu =11568$

Alternative hypothesis: $\mu \neq 11568$

The degrees of freedom are given by:

$df =n-1= 62 -1=61$

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be $t_{\alpha/2}= \pm 2.00$

And the rejection region would be $|t_{calc}| >2.00$

2) Abby made 5 1/2 cups of banana pudding. She served 7/8 cup of the pudding to her kids for dessert.

frez [133]

Answer:

Step-by-step explanation:

we are going to create 5 1/2 into an improper fraction for now, so it is easier to manipulate.

5 1/2 = 11/10

in order to find the answer, we need to set them both to a common denominator(we need to make sure they have the same denominator so it is easier to subtract)

11/2 if we just take 1 of the cups that Abby made and subtract that by 7/8 that give us the answer

11/2 - 1 = 9/2

we will now us the cup we subtracted from that and "give it to the kids"

1 = 8/8

8/8 - 7/8 = 1/8

so we have 1/8 leftover from that cup, so we can add that back

since 1/8 is a hard number to just add off the top of your head, we can just change the denominator of 9/2 into 8 instead of 2:

9/2 = 36/8

1/8 + 36/8 = 37/8

so since 37/8 cannot be simplified anymore, the answer is
