Answer:
The probability that exactly two of the selected bulbs are rated 23-watt is:
= 19%
Step-by-step explanation:
Number of fluorescent light bulbs in the box = 21
7/21 = 13-watt rated light bulbs
8/21 = 18-watt rated light bulbs
6/21 = 23-watt rated light bulbs
The probability of selected a 23-watt rated light bulb = 6/21 = 28.57%
Size of random selection of bulbs = 3
The probability that 2 out of these 3 bulbs are 23-watt rated light bulbs is:
= 6/21 * 2/3 = 19%
b) The probability of selecting 2 of the 3 bulbs from exactly the 23-watt rated bulbs is the probability of the 23-watt rated bulbs being selected given the chance of selecting 2/3.

Answer:
[tex]Blue = 0[/tex]
[tex]Green= 1.25[/tex]
[tex]A= \frac{3}{4}[/tex]
Step-by-step explanation:
The colors on alphabets B and C on the table is not clear enough. So, I will answer using the color
Required
Determine the points on the number line
From the number line each adjacent point is 0.25
Using the above findings, the solution is as follows;
The blue dot is on the 0 point.
So:
[tex]Blue = 0[/tex]
The green dot is on the 1 point after number 1
So:
[tex]Green= 1 + 0.25 * 1[/tex]
[tex]Green= 1 + 0.25[/tex]
[tex]Green= 1.25[/tex]
Lastly:
[tex]A= \frac{3}{4}[/tex]

Answer:
C) x²-2x-15=0
Step-by-step explanation:
You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors. If -3 is a root, one of the factors must be (x+3). If 5 is a root, the other factor must be (x-5).
(x+3)(x-5)
x²-5x+3x-15=0
x²-2x-15=0

Use the point-slope formula to write an equation of the line that passes through (1,0) and has a slope of m=-4. Write the answer in slope- intercept form ( if possible)
Answer:
y = -4x-4
Step-by-step explanation:
We need to find an equation of the line that passes through (1,0) and has a slope of m=-4.
The equation of a line is given by :
y = mx+c
Where
m is slope of line
Put all the values,
y = -4x+c
Put x = 1 and y = 0
So,
0 = -4(1)+c
c = -4
So, the required equation is :
y = -4x-4

Find all numbers whose absolute value is 3 . If there is more than one, separate them with commas. If there are no such numbers, click on "None".
(This is not negative 3)
Answer:
3, and -3
Step-by-step explanation:
Because absolute value is the distance away from zero, |3| and |-3| would both be 3 units away from 0. Be sure to have the negative on the inside if you're trying to make something positive, otherwise -|3| means that the absolute value of 3 would then become negative since the negative sign isn't a part of the absolute. hope this helps!
The numbers whose absolute values is 3 are : 3 and - 3
The absolute value of a number is the distance from zero a number is on the number line. Absolute values measures the distance from zero ignoring whether the distance is to the right or left of the number line.
Three units to the right of Zero = 3
Three units to left of Zero = -3
The absolute value of - 3 represented as |-3| = 3
Hence, The numbers whose distance from zero is 3 on the number line are : 3 and - 3

Two plumbers make house calls. One charges $90 for a visit plus $45 per hour of work. The other charges $65
per visit plus $55 per hour of work. For how many hours of work do the two plumbers charge the same? Help!!
The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for
