Answer:Mean is 22. Median is 19. Mode is 31. Range is 18.
Step-by-step explanation:
Mean: add all the numbers and divide the answer by the number of numbers there were in the beginning.
31+16+13+19+31=110
110/5=22
Median: arrange the numbers in or Eder and find the middle
13,16,19,31,31
The middle is 19.
Mode: is the number that shows up frequently
Mode is 31 as it shows up twice
Range is the difference between the biggest and smallest number
31-13=18
18 is the range.

Answer:
3y-x =-6
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
(x0, y0) is the point = (3, -1)
Given the equation 3xs+y = 1
Get the slope
y = -3x + 1
mx = -3x
m = -3
Since the equation needed is perpendicular to the line, the slope will be expressed as;
M = -1/-3
M = 1/3
Substitute and get the equation needed
y-y0 = m(x-x0)
y - (-1) = 1/3(x-3)
y+1 = 1/3(x-3)
3(y+1) = x-3
3y+3 = x-3
3y - x = -3-3
3y-x =-6
This gives the required equation

A campaign manager for a political candidate released a series of advertisements criticizing their opponent in an upcoming election. Their opponent previously had the support of 45% of voters, and the campaign manager wants to sample voters to test if support for their opponent has decreased.Let p represent the proportion of voters that support their opponent.Which of the following is an appropriate set of hypotheses for their significance test?
Answers
Answer:
C
Step-by-step explanation:
Khan
Considering that we want to test if the support for the opponent has decreased, the appropriate set of hypotheses for their significance test is given by:
C.
[tex]H_0: p = 0.45[/tex]
[tex]H_1: p < 0.45[/tex]
What are the hypothesis tested?At the null hypothesis, we test if the support for the opponent has not decreased, that is, it still is of 45%, hence:
[tex]H_0: p = 0.45[/tex]
At the alternative hypothesis, we test if the support has decreased, that is, it is less than 45%, hence:
[tex]H_1: p < 0.45[/tex]
Hence option C is correct.

find tan 0 where 0 is the angle shown
Answers
Answer:
Because tan represents [tex]\frac{opposite}{adjacent}[/tex] from θ (theta), the equation should be [tex]tan0[/tex]=[tex]\frac{15}{x}[/tex]. Let's leave this equation like that. Now, we need to find the unknown side length, x. We need to use Pythagorean Theorem, because we're given the other two side lengths. The equation should be [tex]x^{2}+15^{2}=17^{2}[/tex]. X should equal ±8 or 8, because a side length can't be a negative value. Now, we can plug in 8 into the equation to get [tex]tan0=\frac{15}{8}[/tex].
The leaders of two youth sports teams randomly select five members of each team and record their ages, as shown.
• Team A 16, 13, 12, 16, 13
• Team B: 10, 13, 16, 16, 10
Which statement appropriately compares the ages of the team members?
Members of Team A and members of Team B are likely the same average (mean) age.
Members of Team A are likely younger, and they have less variability in their ages.
Members of Team A are likely older, and they have more variability in their ages.
D Members of Team A are likely older, and they have less variability in their ages.
Answers
Answer:
Members of Team A are likely older, and they have less variability in their ages.
Step-by-step explanation:
To solve this question, we need to find the mean and the standard deviation for each team.
Team A 16, 13, 12, 16, 13
The mean is:
[tex]M = \frac{16 + 13 + 12 + 16 + 13}{5} = 14[/tex]
The standard deviation is:
[tex]S = \sqrt{\frac{(16-14)^2 + (13-14)^2 + (12-14)^2 + (16-14)^2 + (13-14)^2}{5}} = 1.67[/tex]
Team B: 10, 13, 16, 16, 10
The mean is:
[tex]M = \frac{10 + 13 + 16 + 16 + 10}{5} = 13[/tex]
The standard deviation is:
[tex]S = \sqrt{\frac{(10-13)^2 + (13-13)^2 + (16-13)^2 + (16-13)^2 + (10-13)^2}{5} = 13} = 2.68[/tex]
Which statement appropriately compares the ages of the team members?
Sample of team A has higher mean age, which means that they are likely older. They also have a smaller standard deviation, so they likely have less variability in their ages.

Under his cell phone plan, Alexander pays a flat cost of $69.50 per month and $5 per gigabyte. He wants to keep his bill under $85 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Alexander can use while staying within his budget.
Answers
Answer:
3 gigabytes
Step-by-step explanation:
69.50 dollars + 5 dollars is 74.50 dollars add 5 dollars 79.50 add 5 dollars again and 84.50 Mark brainliest
Inequalities help us to compare two unequal expressions. Alexander can use 3 gigabyte of data to stay within his budget.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that Alexander pays a flat cost of $69.50 per month and $5 per gigabyte. Therefore, the total amount that Alexander pays in a month for x Gb of data used is,
Total Bill amount = Fixed cost + Variable cost for x Gb of data
= $69.50 + $5x
Now, as Alexander wants to keep his bill under $85 per month. Therefore, we can write the inequality as,
Total Bill amount < $85
69.50 + 5x < 85
5x < 85 - 69.50
5x < 15.5
x < 15.5/5
x < 3.1
Therefore, Alexander can use 3 gigabyte of data to stay within his budget.

The Wilson family was one of the first to come to the U.S. They had 8 children. Assuming that the
probability of a child being a girl is .5, find the probability that the Wilson family had:
at least 5 girls?
at most 5 girls?
Answers
Answer:
0.3634 = 36.34% probability that the Wilson family had at least 5 girls.
0.8554 = 85.54% probability that the Wilson family had at most 5 girls.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either it is a girl, or it is not. The probability of a child being a girl is independent of any other child. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [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]
And p is the probability of X happening.
They had 8 children.
This means that [tex]n = 8[/tex]
The probability of a child being a girl is .5
This means that [tex]p = 0.5[/tex]
Probability that the Wilson family had: at least 5 girls?
This is:
[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{8,5}.(0.5)^{5}.(0.5)^{3} = 0.2188[/tex]
[tex]P(X = 6) = C_{8,6}.(0.5)^{6}.(0.5)^{2} = 0.1094[/tex]
[tex]P(X = 7) = C_{8,7}.(0.5)^{7}.(0.5)^{1} = 0.0313[/tex]
[tex]P(X = 8) = C_{8,8}.(0.5)^{8}.(0.5)^{0} = 0.0039[/tex]
[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) = 0.2188 + 0.1094 + 0.0313 + 0.0039 = 0.3634[/tex]
0.3634 = 36.34% probability that the Wilson family had at least 5 girls.
At most 5 girls?
This is:
[tex]P(X \leq 5) = 1 - P(X > 5)[/tex]
In which
[tex]P(X > 5) = P(X = 6) + P(X = 7) + P(X = 8) = 0.1094 + 0.0313 + 0.0039 = 0.1446[/tex]
[tex]P(X \leq 5) = 1 - P(X > 5) = 1 - 0.1446 = 0.8554[/tex]
0.8554 = 85.54% probability that the Wilson family had at most 5 girls.
