how many integers are there between 9 and 100, including 9 and 100?
Answer:
91 Integers
Step-by-step explanation:
Integers are whole numbers that can either be positive, negative, or zero.
Example would be counting numbers
Basically 100-9=91
so there's 91 integers including 9&100
Answer:
92 integers
Step-by-step explanation:
You may think 100-91=9 is correct. But because 9 and 100 are included, you have to add 1 to the answer. However, you don't add 2 since 0 is not included into the integers between 1 and 100.
A farmer wants to plant soy beans and corn. He wants to plant at least 2 acres of soy beans. He has only $1200 to spend and each acre of soy beans costs $200 to plant and each acre of corn costs $100 to plant. Moreover, the farmer has to get the planting done in 12 hours and it takes an hour to plant an acre of soy beans and 2 hours to plant an acre of corn. The farmer profits $500 per acre of soy beans and $300 per acre of corn. If the farmer wants to maximize his profit, how many acres of each should he plant?
9514 1404 393
Answer:
4 acres of each
Step-by-step explanation:
Let s and c represent the number of acres of soybeans and corn, respectively. The problem statement gives rise to several constraints. There is also an objective function to maximize. The linear programming problem can be described by ...
maximize 500s +300c subject to ...
s ≥ 2
200s +100s ≤ 1200 . . . . cost to plant
s + 2c ≤ 12 . . . . . . . . . . . . hours to plant
__
The attached graph shows the objective function is maximized at (s, c) = (4, 4).
The farmer should plant 4 acres each of soybeans and corn.
__
For the solution here, the constraint that s ≥ 2 is irrelevant. If the graph included it, the vertices of the feasible solution space would be (2,5), (4, 4), (6, 0) and (2, 0). The solution that maximizes profit is (4, 4).

The last day of school is in 3 months. Mrs. Fabrizio's birthday is in 10 weeks. What event does Mrs. Fabrizio have to wait longer for? How much longer? (1 month = 4 weeks)
Answer:
She has to wait longer for the last day of school. She will have to wait 2 more weeks for the last day of school compared to her birthday.
Step-by-step explanation:
If each month is four weeks, this means that 3 months will be 12 weeks. (3×4=12)
Mrs. Fabrizio's birthday is in 10 weeks and the last day of school will be in 12 weeks so she has to wait longer for the last day of school.
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?
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.

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?
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.

The four sides of an octagon that are vertical or horizontal are all one length, while the four slanted sides are 4 inches less. If the perimeter is 124 inches, how long are the shorter sides?
9514 1404 393
Answer:
13.5 in
Step-by-step explanation:
Let s represent the length of a short side. Then a long side is (s+4). The perimeter is ...
P = 4s +4(s+4)
124 = 8s +16
15.5 = s +2 . . . . . . divide by 8
13.5 = s . . . . . . . . . subtract 2
The shorter sides are 13.5 inches long.
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.
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.
find tan 0 where 0 is the angle shown
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].

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.
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.
