In a group of 92 students 40 have brown eyes, 35 have hazel eyes, and 17 have blue eyes. Find the probability that a student pic

Oliga [24]

Answer:

as a fraction = 75/92

as a percentage = 81.52%

Step-by-step explanation:

total no of students = 92

probability that a student has hazel or brown eyes = Pr(hazel or brown)

but probability of a or b happening ie Pr(a or b) simply is Pr (a) +Pr (b)

therefore Pr(hazel or brown) = Pr(hazel)+ Pr(brown)

Pr(brown) = (no of brown eyes )/(total set of eyes)

= $40/92$ = 10/23

Pr( hazel) = (no of hazel eyes )/(total set of eyes)

= $35/92$ =35/92

hence Pr(hazel or brown) = (10/23) + (35/92) =75/92

so there's 75/92 probability (or 0.8 out of 1 chance )to choose either hazel or brown randomly

Luba_88 [7]

Answer:

The volume of a sphere:

$V \approx 3053.628$ $cm ^3$

$V \approx 3053.63$ $cm^3$ (Rounded to the nearest hundredth if needed)

Step-by-step explanation:

-To find the volume of sphere, you need this formula to help you solve the problem:

$V = \frac{4}{3} \pi r^3$

-Use the given radius $9$ for the formula:

$V = \frac{4}{3} \pi 9^3$

-Then, you solve:

$V = \frac{4}{3}\pi \times 9^3$

$V = \frac{4}{3} \pi \times 729$

$V = \frac{4 \times 729}{3} \pi$

$V = \frac{2916}{3} \pi$

$V = 972\pi \approx 3053.628$ $cm^3$

-Round up to the nearest hundredth if needed:

$V = 3053.63$ $cm^3$

Select the best sentence in which the vocabulary term is used appropriately.

jekas [21]

I believe it's ' integer ' because there shouldn't be a comma in 'factor' and there should be commas in the others. Hope this helps !
