HELPP PLEASEE!!

Likurg_2 [28]

Answer:

A). Options (C) and (E)

B). 4.8 times

Step-by-step explanation:

Part A

Volume of cylinder (1) = πr²h

= π(6)²(5)

= 565.5 cubic inches

Volume of cone (1) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}(\pi )(6)^2(5)$

= 188.5 cubic inches

Volume of cylinder (2) = πr²h

= π(6)²(15)

= 1696.5 cubic inches

Volume of cone (2) = $\frac{1}{3}\pi (r)^2h$

= $\frac{1}{3}\pi (6)^2(15)$

= 565.5 cubic inches

Volume of sphere = $\frac{4}{3}\pi r^{3}$

= $\frac{4}{3}\pi (6)^{3}$

= 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Options (C) and (E) are the correct options.

Part (B)

$\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}$ = $\frac{904.8}{188.5}=4.8$

Therefore, volume of sphere is 4.8 times the volume of cone (1).

In a group of 100 adults, 70 say they are most likely to do spring houseclean-ing in March, April, or May. Of these 70, the numb

son4ous [18]

Answer:

Adults that clean in March = 18

Adults that clean in April = 48

Adults that clean in May = 4

Step-by-step explanation:

Adults that clean in the months of March, April and May = 70

Let a represent March, b represent April and c represent May.

Therefore, a + b + c = 70 (i)

From the question, the number of adults that clean in April is 14 more than number of the adults cleaning in months of March and May combined.

b - ( a + c) = 14 (ii)

also, the total number who clean in April and May is 2 more than three times the number who clean in March.

b + c - 3a = 2 (iii)

From (i), a + c = 70 - b (iv)

Substituting (iv) into (ii), b - ( 70 - b) = 14

b -70 + b = 14

2b = 84, b =48

Therefore a + c = 70 - 48

a + c = 22; c = 22 - a (v)

Substituting (v) and b = 48 into (iii)

48 + 22 - a -3a = 2

4a = 72, a = 18

Therefore, c = 22 - 18

c = 4

When a particular type of thumbtack is dropped, it will land point up (A flat-top thumbtack resting on its flat top) or point

erma4kov [3.2K]

Answer:

0.48

0.52

Yes

Step-by-step explanation:

Result of experiment :

Point up = 48

Point down = 52

Total number of trials = 100

Recall :

Experimental probability = number of outcomes / number of trials

1.)

P(Landing point up) = 48 / 100 = 0.48

2.)

P(Landing point down) = 52 / 100 = 0.52

3.)

The same result will not occur has the outcomes of trials aren't fixed.

4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.
