Answer:
y = -10/7x - 51
Step-by-step explanation:
y - y1 = m(x - x1)
y + 1 = -10/7(x + 35)
y + 1 = -10/7x - 50
y = -10/7x - 51
What is the mean?
4 6 2 0 6 8 2 4
Answer:
its numbers ...lol lol lol
Answer:
The mean of a set of numbers is the sum divided by the number of terms.
4+6+2+0+6+8+2+48
Cancel the common factor of 4+6+2+0+6+8+2+4 and 8 .
2+3+1+0+3+4+1+24 Simplify the numerator.
164 Divide 16 by 4.
Step-by-step explanation:
If f(x) = 5x - 3 and g(x) = 2x + 9, determine
f(g(4)
Answer:
82
Step-by-step explanation:
f(x) = 5x - 3
g(x) = 2x + 9
f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)
f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82

The number of hours a battery lasts before failing varies from battery to battery. The distribution of Failure times Fallows an Exponential distribution, which is strongly skewed to the right. the central limit theorem says that:_________.
A) as we look at more and more batteries, their average failure time gets ever closer to mean for all batteries of this type.
B) the average failure time of a large number of batteries has a distribution of the same shape (strongly skewed) as the distribution for individual batteries.
C) the average failure time of a large number of batteries has a distribution that is close to Normal.
Answer:
C) the average failure time of a large number of batteries has a distribution that is close to Normal.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Distribution is skewed to the right.
However, for large samples of batteries, the sampling distribution of sample means will be approximately normal, which means that the answer is given by option c.

When using substitution, choose the best choice that describes a possible first step in solving
the following system of equations.
3x – 6y = -12
2x + y = 12
A. ADD (y) to both sides in the bottom equation
B. MULTIPLY the top equation by (-6)
C. SUBTRACT (2x) from both sides in the bottom equation
D. DIVIDE the top equation by (3)
E. SUBTRACT (-6y) to both sides of the top equation
Answer:
C. SUBTRACT (2x) from both sides in the bottom equation
Step-by-step explanation:
Given
[tex]3x - 6y = -12[/tex]
[tex]2x + y = 12[/tex]
Required
The first step of a substitution method
In the second equation, notice that the coefficient of y is 1.
So, the first step is to make y the subject of the formula.
This is achieved by subtracting 2x from both sides of the equation.
[tex]2x + y = 12[/tex]
[tex]2x - 2x + y = 12 - 2x[/tex]
[tex]y = 12 - 2x[/tex]
Hence: (c) is true

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44

Basically everything is in the picture PLEASE HELP me ASAP I'm BEGGING
Answer:
Just find the area of the big one, and then subtract the area of the small one. This will give you the difference in area between the big and the small one (or in other words, the shaded region).
5 * 12 = 60cm ^ 2
3 * 8 = 24cm ^ 2
60 - 24 = Area of the Shaded Region (cm ^ 2)
Answer: 36 cm^2
Step-by-step explanation:
Area of a rectangle = length x width.
The area of the blue rectangle is
12 cm x 5 cm= 60 cm^2
The area of the white rectangle is
8 cm x 3 cm = 24 cm ^2
Subtract the area of the white rectangle from the blue rectangle.
60 cm^2 - 24 cm^2 = 36 cm^2

Y=-6x
Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b
Y=-6x+0
Y=-6x
