Solve rs + t = u for the variable s

Fiesta28 [93]

Answer:

$s=\frac{u}{r} -\frac{t}{r}$

Step-by-step explanation:

You have to move the variables (r and t) with u to isolate s.

$rs+t=u$

$-t$ $-t$

------------------------

$rs=u-t$

÷ $r$ ÷ $r$

------------------------

$s=\frac{u}{r} -\frac{t}{r}$

Mindy has 4 red lollipops, 2 green, and 3 blue lollipops to choose from. What is the complement of her choosing a blue lollipop?

Masteriza [31]

Answer: I’m not sure what compliment is but she would have to pick 7 to guarantee that she gets at least 1 blue lollipop

Step-by-step explanation:

There are 9 in total. 6 not blue. There are 3 blue. Assuming she gets terrible luck, she would have to take all of the non blue first which is 6. Then she would take another one to make sure she gets at least 1 blue lollipop

MAXImum [283]

Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim

$H_{0} = 45\\H_{1} < 45\\\\$

The test statistic :

T = (x - μ) ÷ (s/√(n))

T = (43 - 45) ÷ (15/√70)

T = - 2 ÷ 1.7928429

T = -1.1155

At α = 0.05

Pvalue :

Degree of freedom, df = 70 - 1 = 69

Pvalue = 0.134

Decison region :

Reject $H_{0}$ if Pvalue < α

Since Pvalue > α We fail to reject the Null
