4. There are 10 cheerleading squads performing in a competition. The
order of the performances is determined at random. What is the
probability that your squad performs first and your friend's squad performs
second?
Answer:
0.011 or 1/90
Step-by-step explanation:
Since the order of the performances is determined at random the probability of each squad is constant that 1/10
The probability of your squad is 1/10
Given that the first selected was yours (1/10) nine squads are left . Therefore the probability of your friends squad is 1/9.
Hence the probability that your squad performs first and your friend's squad performs second is (1/10 * 1/9) 1/90 or 0.011

What is histogram?A histogram is an approximate representation of the distribution of numerical data. A histogram is a graph that shows the frequency of numerical data using rectangles. The height of a rectangle (the vertical axis) represents the distribution frequency of a variable (the amount, or how often that variable appears).
here, we have,
We are given a the 30 data points which represent the best lifetime baseball batting averages of all time, arranged in order from lowest to highest.
As we know that we could obtain a frequency table from the following set of data points and histogram is a good way to represent the frequency data. ( i.e. a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins ).
Hence, the given statement,
A frequency table for these data can best be graphically displayed as a bar graph. That is, it should not be displayed as a histogram is a FALSE STATEMENT.

Please look at the following numbers listed above and determine a relationship:
Are they exponential or linear? Why?
Answer:
neither exponential nor linear
Step-by-step explanation:
A linear relationship will show a common difference between adjacent value. Here, the first differences between the first three values are 5 and 33. They are not the same, so the relation is not linear.
__
An exponential relationship will show first differences that are continuously increasing or decreasing by increasing or decreasing amounts (respectively).
As we showed, the difference between May 28 and May 27 is 33. This is more than the previous difference. However, the difference between May 30 and May 31 is only 28, which is less than a previous difference.
The relation is not exponential.
__
A graph points up the non-linearity of the relation.

Answer:
12 square units.
Step-by-step explanation:
We must find the area of each shape and add together. The area of a triangle is 1/2 base times height. The smaller triangles area is 2 and the larger triangle's area is 6. The area of the square is 4... so when all added together, we have 12.
In a cartons of bulbs, 90% contain no defective bulbs, 5% contain one defective bulb, 3% contain two defective bulbs, and 2% contain three defective bulbs. Find the mean and standard deviation for the number of defective bulbs.
Answer:
Mean, E(x) = 0.17
Variance, V(x) = 0.12
Step-by-step explanation:
90% contains no defective bulbs, P(X=0) = 0.9
5% contain one defective bulbs, P(X=1) = 0.05
3% contain two defective bulbs, P(X=2) = 0.03
2% contain three defective bulbs, P(X=3) = 0.02
The mean for the number of defective bulbs:
[tex]E(X) = \sum XP(X)\\E(X) = (0*0.9) + (1*0.05) + (2*0.03) + (3* 0.02)\\E(X) = 0 + 0.05 + 0.06 + 0.06\\E(X) = 0.17[/tex]
Variance for the defective bulbs:
[tex]V(x) = (\sum x^{2}P(x) ) - \mu^2[/tex]
[tex]\sum x^{2}P(x) = (0^2*0.9) + (1^2*0.05) + (2^2*0.03) + (3^2* 0.02)\\\sum x^{2}P(x) = 0.05 + 0.12 + 0.12\\\sum x^{2}P(x) = 0.29[/tex]
V(x) = 0.29 - 0.17
V(x) = 0.12

43 milk jugs are in a fridge with 11 that are spoiled. 5 jugs are randomly selected. what are the odds that the first two are good and the last three are spoiled?
Answer:
0.85% probability that the first two are good and the last three are spoiled
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
2 spoiled, from a set of 43-11 = 32.
3 spoiled, from a set of 11.
So
[tex]D = C_{32,2}*C_{11,3} = \frac{32!}{2!(32-2)!}*\frac{11!}{3!(11-3)!} = 982080[/tex]
Total outcomes:
5 jugs from a set of 43.
[tex]T = C_{43,5} = \frac{43!}{5!(43-5)!} = 115511760[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{982080}{115511760} = 0.0085[/tex]
0.85% probability that the first two are good and the last three are spoiled

All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make a
statistical inference about the mean of the normally distributed population from which it was drawn?
ME.
The margin of error is multiplied by /05
The margin of error is multiplied by 12
The margin of error is multiplied by 05,
The margin of error is multiplied by 2.
Save and Exit
Answer:
The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.
Step-by-step explanation:
The margin of error is:
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which z is related to the confidence level, [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
The margin of error is inverse proportional to the square root of the sample size.
Then
Sample size n:
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
Modified(half the sample size):
[tex]M_{M} = z*\frac{\sigma}{\sqrt{0.5n}}[/tex]
Ratio
[tex]\frac{M_{M}}{M} = \frac{z*\frac{\sigma}{\sqrt{0.5n}}}{z*\frac{\sigma}{\sqrt{n}}} = \frac{\sqrt{n}}{\sqrt{0.5n}} = \frac{\sqrt{n}}{\sqrt{0.5}*\sqrt{n}} = \frac{1}{\sqrt{0.5}} = 1.41[/tex]
The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.

There are 300 packets of 1 kg of sugar in a container. A) How many kg are 3 5 of the total amount? B) How much money will be raised from the sale of the 3 5 of the total amount, if the price of each package is 2'5 euros?
Answer:
A) 180 packets
B) €450
Step-by-step explanation:
A) There are 300 packets of 1 kg of sugar in a container.
3/5 of the total amount is:
3 / 5 * 300 = 180 packets
B) Each packet goes for €2.50.
3/5 of the total amount is 180 packets, therefore, 180 packets will go for:
2.5 * 180 = €450

Natalie buys a new car. In the first month, the odometer on the car records 800 miles. From past experience, she expects to drive 900 miles per month.
Select all the functions that can be used to find the number of miles, f(n), recorded on the odometer after n months.
Answer:
[tex]\begin{aligned}\bullet\ &f(1)=800;f(n)=f(n-1)+900, \text{for $n\ge 2$}\\ \bullet\ & f(n)=900n-100\end{aligned}[/tex]
Step-by-step explanation:
See attachment for the figure.
Using arithmetic sequence with a first term of 800 and a common difference of 900. The general form for such a sequence is given by,
an = a1 +d(n -1)
an = 800 +900(n -1) = 900n -100
If n is the function, this can be written as,
f(n) = 900n -100
When considered as a recursive relation, we find the first term is still 800:
f(1) = 800
and that each term is 900 more than the previous one:
f(n) = f(n-1) +900 . . . . for n ≥ 2

The figure shows two regular pentagons. What is the perimeter of the larger pentagon?
A. 5n
B. 10n
C. 15n
D. 60n
Answer:
As shown in picture,
perimeter of inside pentagon: p1 = n + n + n + n + n = 5n
ratio between inside pentagon and outside pentagon: r = 6/(6 + 6) = 1/2
=> perimeter of outside pentagon: p2 = 2 x p1 = 2 x 5n = 10n
=> Option B is correct

need help ASAP!!!! needs explanation as well
Answer:
1. The rocket was launched from a height of 180 feet.
=> Valid because at time = 0 sec, height = 180 feet (as shown in table)
2.The maximum height of the rocket occurred 3 seconds after launch.
=> Valid because at time = 3 sec, height = 324 feet (greatest value in second row of table).
3.The rocket was in the air approximately 6 sec before hitting ground.
=> Not valid because the time in table in about 7 sec (from 0 to 7), but all of the heights are greater than 0 (the rocket has not hit the ground yet).
4. The rocket was above 300 feet for approximately 2 seconds.
=> Valid because from sec 2 to sec 4: the height is greater than 300 (308, 324, and 308)
=> Option 3 is not valid.
Hope this helps!

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)^nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
