A local Little league has a total of 60 players, 80% of whom are right-handed. How many right-handed players are there?

Damm [24]

Answer:

48 right-handed players

Step-by-step explanation:

first, make an equation

$\frac{80}{100} =\frac{x}{60}$

then, cross multiply and the new equation is

$100x=4800$

finally, divide by 100 on both sides to isolate the x and you get

x=48

Na dives into a pool off of a springboard high dive. Her height (in meters above the water), x xx seconds after diving, is model

Anna71 [15]

Answer:

Step-by-step explanation:

What you have here is the factored form of the quadratic

$ax^2+bx+c$

where a is the term representing the pull of gravity, b is the upwards vertical velocity and c is the initial height. If we FOIL that out, we get the equation in a form that is easily analyzed for velocity and initial height.

$y=-5x^2+10x+15$

This tells us that the initial vertical velocity of the dive was 10 m/sec, and that she was 15 meters up at the time of diving.

The waiting times on hold for a call to a customer service department are observed to have the following probability distributio

Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

$\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}$

number of calls (x) waiting time f(x) in minutes f(x) *(x)

0 0 0

2 3 6

4 10 40

6 15 90

8 10 80

10 6 60

$\sum x = 30$ $\sum f(x) *x = 276$

Therefore:

$\sum (f(X)) = \dfrac{276}{30}$

$\sum (f(X)) = 9.2$
