how many different teams containing 5 members each can be formed from a group of 9 players
Answer:
1 team with 4 extra people
Step-by-step explanation:
Final answer:
126 different teams can be formed from a group of 9 players.
Explanation:
To determine how many different teams containing 5 members each can be formed from a group of 9 players, we use the concept of combinations in mathematics.
The number of combinations is given by the formula for n choose r (nCr), which is n! / (r! * (n-r)!),
where
n is the total number of items to choose from,
r is the number of items to be chosen, and
! denotes factorial.
In this case, n=9 and r=5.
Thus, using the combinations formula, we get:
9C5 = 9! / (5! * (9-5)!)
= 9! / (5! * 4!)
= (9 * 8 * 7 * 6) / (4 * 3 * 2 * 1)
= 126 different teams.
Therefore, 126 different teams can be formed from a group of 9 players.

The IQR is the best measurement of spread for badminton games and dance competitions.
The IQR is a better measure of spread for dance competitions than for badminton games.
The standard deviation is the best measurement of spread for badminton games and dance competitions.
Answer:
The IQR is a better measure of spread for dance competitions than for badminton games.
Step-by-step explanation:
I understand from "Dance Competition box plot has interquartile ranges approximately between 60 and 130" that quartile 1 is at 60 and quartile 3 is at 130, then, the interquartile range (IQR) is 130 - 60 = 70.
Similarly, from Badminton box plot, quartile 1 is at 90 and quartile 3 is at 150, then, the interquartile range is 150 - 90 = 60.
IQR is a measure of statistical dispersion, that is, as IQR increase, spread increase.
The statement that best describes how to measure the spread of the data in the given box plot is: B. The IQR is the best measurement of spread for badminton games and dance competitions.
Recall:
Interquartile range (IQR) is the difference between the first quartile and the third quartile.From a box plot, the first quartile and the third quartile can be found at both ends of the rectangular box, which can be used to determine the IQR of a data set.IQR is a measure of spread.Since the data is plotted on a box plot, IQR can easily be gotten which is a measure of spread.
Therefore, the statement that best describes how to measure the spread of the data in the given box plot is: B. The IQR is the best measurement of spread for badminton games and dance competitions.

There are 38,412 nurses registered in the region this year. There are about __________
less nurses than last year when there were 42,198 nurses.
a. 3,800 b. 3,900 c. 4,600
Answer:
A. 3,800
Step-by-step explanation:
42,198 - 38,412 = 3786
Final answer:
To find the decrease in the number of registered nurses from last year, subtract this year's nurse count, 38,412, from last year's, 42,198, which results in 3,786, rounded to 3,800 (option a).
Explanation:
The question asks to calculate the difference in the number of nurses registered this year compared to last year. The registered nurses this year are 38,412, and last year there were 42,198 nurses. To find the difference, we subtract the number of nurses this year from the number last year.
Number of nurses last year: 42,198
Number of nurses this year: 38,412
Difference = 42,198 - 38,412 = 3,786
The closest round number to the actual difference (3,786) is 3,800, which is option (a).

The average height of a 17-year-old girl in the US is about 64 inches with a
standard deviation of 2.8 inches. Without using a calculator, estimate the
probability of 17-year-old girl in the US that are between 58.4 inches and 69.6
inches.
the probability of 17-year-old girl in the US that are between 58.4 inches and 69.6 inches is 0.9544 .
Step-by-step explanation:
Step 1: Sketch the curve.
The probability that 58.4<X<69.6 is equal to the blue area under the curve.
Step 2:
Since μ=64 and σ=2.8 we have:
P ( 58.4<X<69.6 ) = P ( 58.4−64 < X−μ < 69.6−64 )=P ( 58.4−64/2.8 < X−μ/σ< 69.6−64/2.8)
Since Z = x−μ/σ , 58.4−64/2.8=−2 and 69.6−64/2.8=2 we have:
P ( 58.4<X<69.6 )=P ( −2<Z<2 )
Step 3: Use the standard normal table to conclude that:
P ( −2<Z<2 )=0.9544
Therefore, the probability of 17-year-old girl in the US that are between 58.4 inches and 69.6 inches is 0.9544 .
3. A balancing balloon toy is in the shape of a hemisphere (half-sphere) attached to the base of a cone. If the toy is 4ft tall and 2ft wide, what is the volume of the toy? Round your answer to two decimal places.
Answer:
The volume of the toy is [tex]V=5.23\ ft^3[/tex]
Step-by-step explanation:
step 1
Find the volume of the hemisphere
The volume of the hemisphere is given by the formula
[tex]V=\frac{2}{3}\pi r^{3}[/tex]
In this problem, the wide of the toy is equal to the diameter of the hemisphere
so
[tex]D=2\ ft[/tex]
[tex]r=2/2=1\ ft[/tex] ----> the radius is half the diameter
substitute
[tex]V=\frac{2}{3} \pi (1)^{3}=\frac{2}{3} \pi\ ft^3[/tex]
step 2
Find the volume of the cone
The volume of the cone is given by
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we know that
The radius of the cone is the same that the radius of the hemisphere
so
[tex]r=1\ ft[/tex]
The height of the cone is equal to subtract the radius of the hemisphere from the height of the toy
[tex]h=4-1=3\ ft[/tex]
substitute the given values
[tex]V=\frac{1}{3}\pi (1)^{2}(3)=\pi\ ft^3[/tex]
step 3
Find the volume of the toy
we know that
The volume of the toy, is equal to the volume of the cone plus the volume of the hemisphere.
so
[tex]V=(\frac{2}{3} \pi+\pi)\ ft^3[/tex]
[tex]V=(\frac{5}{3}\pi)\ ft^3[/tex]
assume
[tex]\pi=3.14[/tex]
[tex]V=\frac{5}{3}(3.14)=5.23\ ft^3[/tex]

Xerxes, Murray, Norah, Stav, Zeke, Cam, and Georgia are invited to a dinner party. They arrive in a random order and all arrive at different times. What is the probability that Xeres arrives first?
Answer in decimal form. Round to 3 decimal places as needed.
Answer:
0.143
Step-by-step explanation:
From counting principle, we can say that:
There are 7! ways of the 7 people to arrive first. Any one of them can come first. But, what is the probability that Xerxes with arrive first?
We take that Xerxes is the first one to arrive, then from the 7 - 1 = 6 remaining people, they can arrive in 6! ways. So
Probability Xerxes arrives first = 6!/7! = 0.1429
Rounding to 3 decimal places, it will be:
Probability Xerxes arrives first = 0.143

this is a fraction does it have any excluded values and why
Final answer:
The excluded values for the fraction are t = -3/2 and t = 3/2, which are obtained by factoring the denominator as a difference of squares and setting each factor equal to zero.
Explanation:
The question involves determining the excluded values for the fraction 7t2 − 14t over 4t2 − 9. Excluded values are values of t that would make the denominator equal to zero, since division by zero is undefined in mathematics. To identify the excluded values, we must factor the denominator and then set it to zero and solve for t, to see for which values the fraction is undefined.
First, notice that the denominator is a difference of squares, which factors as follows:
4t2 − 9 = (2t + 3)(2t - 3)Next, we set each factor of the denominator equal to zero to find the excluded values:
2t + 3 = 0, which yields t = -3/22t - 3 = 0, which yields t = 3/2Therefore, the excluded values are t = -3/2 and t = 3/2.
The excluded values for the fraction are t = -3/2 and t = 3/2, which are obtained by factoring the denominator as a difference of squares and setting each factor equal to zero.

2t - 3 = 0, which yields t = 3/2
