If the amount of air in a spherical balloon is 288 cu. in., what is the radius of the balloon? 6 inches 7.3 inches 72 inches

garik1379 [7]

Answer:

6in

Step-by-step explanation:

The volume of a spherical balloon is 4/3 π R^3.

So 288π = 4/3 π R^3

The factors of π cancel out. Divide both sides by 4/3 to get:

216 cubic inches = R^3

Take the cube root of both sides, and you find that R = 6 inches

Determine whether each of the following sequences are arithmetic, geometric or neither. If arithmetic, state the common differen

Fudgin [204]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's see if the sequence is Arithmetic or Geometric :}$

$\textsf{If the difference between successive terms is }$ $\textsf{equal then, the terms are in AP}$

$\sf{ \dfrac{14}{3}- \dfrac{13}{3} = \dfrac{1}{3}}$

$\sf{ {5}{}- \dfrac{14}{3} = \dfrac{15-14}{3} =\dfrac{1}{3}}$

$\textsf{Since the common difference is same, }$ $\textsf{we can infer that it's an Arithmetic progression}$ $\textsf{with common difference of } \sf \dfrac{1}{3}$

Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year

Mumz [18]

Answer:

Yes

Step-by-step explanation:

Let p1 represent proportion of women and p2 proportion of men. The null and alternative hypothesis will be as follows

Null hypothesis

$H_o$ =p2-p1 ≤0

Alternative hypothesis

$H_a$ =p2-p1>0

Sample proportion of women, p1=74/200=0.37

Sample proportion of men is p2=104/200=0.52

Level of significance is 0.01

Pooled proportion= $\frac {104+74}{200+200}=0.445$

Test statistic

$z=\frac {(0.52-0.37)-0}{0.445(1-0.445)*\sqrt{(1/200+1/200)}}=6.9124$

p-value=P(Z≥z)=P(Z≥6.9124)=P(Z≤-6.9124)=0

Since the value of p is less than 0.01, we reject null hypothesis. There’s sufficient evidence that a greater proportion of men is expecting to get a raise
