The volume of a boys' basketball is 434 cubic inches. Dan would like to get a ball
Nataly_w [17]

Answer:

The correct answer is A. 9.4 inches.

Step-by-step explanation:

Given that the volume of a boys' basketball is 434 cubic inches, and Dan would like to get a ball with half the volume for his son, to determine what is the diameter of the ball that Dan will buy for his son, the following calculation has to be done, knowing that the volume of a sphere is four thirds multiplied by pi multiplied by the radius cubed:

4/3 x 3.14 x X ^ 3 = 434

4.186 x X ^ 3 = 434

X ^ 3 = 434 / 4.186

X = 3√ 103.662

X = 4.7

In turn, since the radius of a sphere is equal to half its diameter, the diameter of the basketball is 9.4 inches (4.7 x 2).

Fifty-five percent of the members of the junior varsity swim team wear glasses. Of the team memebers who do not wear glasses, 30
GarryVolchara [31]

the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade is 14%.

Given, the members of the junior varsity swim team wear glasses is 55%.

And the members of junior varsity swim team who do not wear glasses and in 10th grade is 30%.

Let the total no. of members be x.

So, the members of the junior varsity swim team wear glasses (55%),will be

0.55x.

The total number of members not wearing glasses, will be

x - 0.55 x = 0.45 x.

Now, the no. of members not wearing glasses and in 10th grade will be,

\frac{0.45x\times30}{100} =0.135x

We know that the probability of an event E, P(E) will be,

P(E)=\frac{No.\ of Favourable\ outcomes}{total \ no. \ of \ outcomes}

So, the probability for no. of members not wearing glasses and in 10th grade will be,

P(E)=\dfrac{0.135x}{x}

P(E)=0.135\\\\P(E)=13.5 \%

Hence the nearest whole percent of probability is 14%.
