Answer:

14

Step-by-step explanation:

Total number of chips = 500

Percentage of green chips = 28%

P(green chips) = 0.28

Expected number of green chips from a simple of 50

Sample size, n = 50

p of green chips = 0.28

Recall:

Mean, m = n*p

Expected number of green chips = 50 * 0.28 = 14

14 green chips

Which is true about the solution to the system of inequalities shown? y > 3x + 1 y < 3x – 3 On a coordinate plane, 2 solid
Novay_Z [31]

The true option about the solution to the system of inequalities shown is  B. The second line has a positive slope and goes through (0, negative 3) and (1, 0).

<h3>How to explain the inequality?</h3>

Plot these ordered pairs on a coordinate plane and connect them by straight lines.

The sign of both inequalities is "<"which means both lines are dotted and everything below the lines is shaded.

From the below graph it is clear that all values are satisfied.

A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?
Natasha_Volkova [10]
First, find the slope between the two points. 
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation. 
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case. 
y= 1/3x or in other words y= x/3

D = rt what does r stand for
AnnyKZ [126]
In the equation D = rt, the r stands for rate. The equation is saying that distance equals the rate at which you traveled multiplied with the time you traveled. In other words, r is the speed traveled. Example: If the rate at which you travel is 35 miles per hour and you traveled for 2 hours, then you have traveled 35 miles times 2 or 70 miles.

This is factoring quadratics with a leading coefficient: 5p to the 2 power - 52p + 20
Mashutka [201]

Answer:

(-5p + 2)(-p + 10)

Step-by-step explanation:

5p^{2}-52p + 20

(-5p + 2)(-p + 10)

You can double check this by using the distributive property..

-5p * -p = -5p^2

2*-p = -2p

10*-5p = -50p

10*2 = 20

-5p^2 + -2p + -50p + 20

Now we combine like terms and simplify

-5p^2 -52p + 20

So, we are correct

PLease help tem points
Kobotan [32]

4 is the x value and -3/4 is the y value. (x,y)

To plot this point, move over to the right to 4, then go down 3/4. So the point will be in the bottom right quadrant.
