Find each percent decrease. Round to the nearest percent.
From 39 seconds to 13 seconds
O 53%
0 67%
057%
O 63%
Answer:
67%
Step-by-step explanation:
First of all, we must find the decrease;
39 - 13
=26
Then we can find the percentage decrease
26/13 ×100 =66.666..which can be written as 67.

Let’s say that you have a square garden in your backyard. One side of the garden has a length of x + 4. Can you give an expression that we could use to represent the area of the garden?
Answer:
[tex]A=(x+4)^2\text{ or } A=x^2+8x+16[/tex]
Step-by-step explanation:
We have a square garden. One side of the garden has a length of (x + 4).
And we want to write an expression that could represent the area of the garden.
Remember that for a square, all sides have equivalent lengths. So, every side measures (x + 4). The area of a square is given by:
[tex]A=s^2[/tex]
Where s is the length of one side.
Substitute:
[tex]A=(x+4)^2[/tex]
Expand if desired. Hence, the expression for the area is:
[tex]A=x^2+8x+16[/tex]

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

Step-by-step explanation:
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.

A population has a standard deviation of 3.26. What is the approximate standard error of the mean for a sample size of 35?
A.
1.65
B.
0.55
C.
0.09
D.
1.10
Answer:
0.55
Step-by-step explanation:
Standard Error of the mean= Standard deviation/sample size
[tex]=\frac{3.26}{\sqrt{35} }[/tex]

Write an equation for the graph, where
y
depends on
x
.
Answer:
y= -2x+4
Step-by-step explanation:
1) if they want an equation where y depends on x, then you need to write the equation in slope-intercept form. Or... y=mx+b where m is the slope and b in the y-intercept.
2) looking at the line, it intercepts y at 4, so that is your intercepts or "b"
3) the slope is the change in the y values over the change in the x values for any two points. Notice if you choose the point (0,4) and (2,0) the change in the y values is -4 and the change in the x values is 2. Therefore, the slope is -4/2 or -2. -2 is your m.
4) once you plug those values in to y=mx+b, you have y= -2x+4
Please please need help on this one
Answer:
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
