The sample space in the problem is 6 girls and 7 boys. If ten players are to be chosen composing of three or four girls, then
for 3 girls:6C3 * 7C7 / 13C 10 = 0.06993
for 4 girls: 6C4 * 7C6 / 13C 10 = 0.3671
we add the two and the answer is 0.4371

Answer:

Slope = -17

Step-by-step explanation:

We are given the equation of the line to be:

y = -17x + 47/3 which is in the slope-intercept form.

Recall: equation of a line in slope-intercept form takes the following format:

y = mx + b

Where,

m = slope of the line

b = y-intercept of the line

Thus, the slope of the line (m), y = -17x + 47/3 would be -17

Kate walks 5 miles in 2 hours at a steady pace. How far can she walk in 1 hour and 15 minutes? Explain your reasoning.
Scrat [10]

Answer:

3.125

Step-by-step explanation:

Kate walks 5 miles in 2 hours (120 minutes)

The distance she can works in 1 hour 15 minutes can be calculated as follows

This can be calculated using proportion

d/75= 5/120

Cross multiply

d×120= 75×5

120d= 375

d= 375/120

= 3.125

A pyramid has a square base that measures 20 inches on each side and 30 inches high. Find the volume of the pyramid.
irinina [24]

The volume of pyramid is 4000 inch³.

<h3>What is Volume?</h3>

Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. Volume is measured in cubic units like m³, cm³, in³, etc. Volume is sometimes referred to as capacity.

The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

Given:

base = 20 inches

height = 30 inches

Now, volume of pyramid

Volume = a²h/3

Volume = 20 x 20 x 30 /3

Volume = 400 x 10

Volume = 4000 inch³

Hence, the volume of pyramid is 4000 inch³.
