ab + 7a + 4b + 28
Answer:
(b + 7)(a + 4)
Step-by-step explanation:
ab + 7a + 4b + 28
separate the polynomial into 2 sections
(ab + 7a) (+ 4b + 28)
simplify each expression
a(b + 7)
4(b + 7)
you see that you have (b + 7) in both expressions. take that aside.
(b + 7)
you are left with a and positive 4. put these two together
(a + 4)
now put the expressions together
(b + 7)(a + 4)
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{(b + 7)(a + 4)}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ab + 7a + 4b + 28}[/tex]
Take a common
[tex] \dashrightarrow{ \sf{a(b + 7) + 4b + 28}}[/tex]
Take 4 common
[tex] \dashrightarrow{ \sf{a(b + 7) + 4(b + 7)}}[/tex]
Take ( b + 7 ) common
[tex] \dashrightarrow{ \sf{(b + 7)(a + 4)}}[/tex]

There are nine different positions on a baseball team. If a team has 17 players how many different line-ups can the team make? (Assume every player can play every position.) The team can make different line-ups. Baseball games consist of nine innings. A team wants to change its line-up every inning. If no game goes to extra innings, and a season consists of 147 games, how many complete seasons can the team play without repeating a line-up? The team can play complete seasons without repeating a line-up. (Your answer should be an integer.)
Answer:
A) 24310
B) 18 seasons
Step-by-step explanation:
A) We are given the team has 17 players and there are 9 different positions in the team.
This is a combination question and thus, the number of different line-ups the team can make is;
C(17, 9) = 24310
B) We are told the basketball games consists of 9 innings.
Thus,
Number of games you can fill = 24310/9 = 2701.1111
And then we are told a season consists of 147 games.
Thus;
Number of complete seasons can the team play without repeating a line-up =
2701.1111/147 ≈ 18 seasons

Answer:
p = 2L + 2W
total fencing = 100 feet
we have w = 20
then
100 = 2L + 2W
100 = 2L + 2*20
100 -40 = 2L
2L = 60
L= 60/2 = 30
what are the steps and answer for - 5n - 2 = 38
Answer:

Why is it useful to write a ratio of fractions as a unit rate?
Answer:
When a ratio is written in fraction form, the fraction should be simplified. If it is an improper fraction, we do not change it to a mixed number. Because a ratio compares two quantities, we would leave a ratio as 41 instead of simplifying it to 4 so that we can see the two parts of the ratio.

Your target number of calories is 2400 per day to lose weight, but you are consuming 3200 calories per day. Your target is what percentage of your consuming calories? Insert your answer as a whole percentage WITHOUT the % symbol.
Answer:
75
Step-by-step explanation:
Your target number of calories is 2,400 per day inorder to lose some amount of weight.
Instead 3,200 calories is consumed
Therefore the percentage of target that is consumed can be calculated as follows
= 2,400/3,200 × 100
= 0.75 × 100
= 75
Hence the percentage of calories that is consumed is 75

If random variable X has a binomial distribution with n=15 and P(success) =p= 0.6, find the mean of X. That is, find E(X). Round to the whole number. Do not use decimals. Answer:
Answer:
9
Step-by-step explanation:
E(X) = np
E(X) = (15) (0.6)
E(X) = 9
The mean of the X is 9.
What is the mean of the binomial distribution?The mean of a binomial distribution is the expected value (long-run average) of the number of successes in the given number of trials.
Formula for calculating mean of binomial distribution[tex]\mu_{x} = n.p[/tex]
where,
[tex]\mu_{x}[/tex] is the mean of the binomial distribution
n is the number of trials
and, p is the probability of success
According to the given question.
We have
Number of trials, n = 15
Probability of success, p = 0.6
Therefore, the mean of X is given by
[tex]E(X) = 15(0.6)[/tex]
⇒ [tex]E(X) = 9[/tex]
Hence, the mean of the X is 9.

Consider a problem where we are rolling 2 dices where each dice has 6 faces numbered from 1 to 6.Answer the following questions:(1) What is the sample space?(2) If the event we are interested in is the sum being 10, what would be the probability of observingsuch an event?(3) If the event we are interested in is the sum being 6, what would be the probability of observingsuch an event?
Answer:
1. See Explanation for Sample Space
2. [tex]P(10) = \frac{1}{12}[/tex]
3. [tex]P(6) = \frac{5}{36}[/tex]
Step-by-step explanation:
Given
Roll of Two die
Solving (1): The Sample Space
Represent the first dice with S1 and the second with S2
[tex]S_1 = \{1,2,3,4,5,6\}[/tex]
[tex]S_2 = \{1,2,3,4,5,6\}[/tex]
The sample space of both die is:
[tex]S = (1,1)(1,2)(1,3)(1,4)(1,5)(1,6)(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)[/tex][tex](4,1)(4,2)(4,3)(4,4)(4,5)(4,6)(55,1)(5,2)(5,3)(5,4)(5,5)(5,6)(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)}\}[/tex]
Solving (2): Probability of Sum being 10
First, we need to add the outcome of each roll in (1) above:
[tex]S = \{2,3,4,5,6,7, 3,4,5,6,7,8, 4,5,6,7,8,9, 5,6,7,8,9,10, 6,7,8,9,10,11 7,8,9,10,11,12\}[/tex][tex]n(S) = 36[/tex]
[tex]n(10) = 3[/tex]
The required probability is:
[tex]P(10)= \frac{3}{36}[/tex]
[tex]P(10) = \frac{1}{12}[/tex]
Solving (3): Probability of Sum being 6
[tex]n(S) = 36[/tex]
[tex]n(6) = 5[/tex]
The required probability is:
[tex]P(6) = \frac{5}{36}[/tex]
At 6 am, the temperature was 73 degrees Fahrenheit. By noon, then temperature had rose 8 degrees. At 4 pm, the temperature was 5 degrees warmer than it was at noon. By 9 pm, the temperature had dropped 16 degrees. What was the temperature at 9 pm?
Answer:
70 degrees Fahrenheit
Answer:
70
Step-by-step explanation:
We started at 73 degrees and the temperature rose by 8 degrees so 73 + 8 = 81. At 4 pm, the temperature rose again by 5 degrees so 81 + 5 = 86. By 9 pm, the temperature dropped 16 degrees so 86 - 16 = 70, Therefore, the temperature at 9 pm was 70 degrees.

Here is a breakdown of some of the different types of “negative” information and how long you can expect the information to be on your Equifax credit report:
Late payments remain on a credit report for up to seven years from the original delinquency date -- the date of the missed payment.
Bankruptcy public records stay on your Equifax credit report from seven to 10 years, depending on the type of bankruptcy.
Other negative accounts, such as repossessions, can also stay on your report for up to seven years from the date of the first missed payment that led to the negative status.
Hence The most likely number of years that this negative information will remain on their credit reports will be 7 to 10 years.

A. Angle
B. Obtuse
C. Vertex
D. Triangle
Answer:
The term that best describes a figure formed by three segments connecting three non-collinear points is:
Triangle.
Step-by-step explanation:
Step-by-step explanation:
We know that with the help of just one point we can't form any figure.
With the help of two points a line segment can be formed.
And with the help of three points if the three points are collinear a triangle can be formed.
Hence, the term that best describes a figure formed by three segments connecting three non-collinear points is:
Triangle.

If UV = 13, VW = 3x − 5, and UW = 5x − 18, what is UW? Simplify your answer and write it as a proper fraction, mixed number, or integer.
I got stuck here. If you could (or not) type step by step.
Since UV and VW make up UW, we can set add together UV and VW and set them equal to UW.
5x - 18 = 13 + 3x - 5
Let's combine like terms on the right side.
5x - 18 = 3x + 8
Subtract 3x from both sides and add 18 to both sides.
2x = 26
Divide both sides by 2
x = 13
We know that UW = 5x - 18. Let's plug 13 in for x.
UW = 5(13) - 18 = 65 - 18 = 47.

Required
Find the average speed over these intervals
The function is not given; so, I'll represent the function as s(t)
When [tex]t = 2;[/tex]
[tex]s(t)= s(2)[/tex]
