What is the slope of the line that passes through the points (5,11) and (14,-10)
Answers
Answer:
the picture has the answer on it
Step-by-step explanation:
The slope of the straight line that passes through the points (5,11) and (14,-10) is [tex]\frac{-7}{3}[/tex].
What is a straight line?''A straight line is an endless one-dimensional figure that has no width. A straight line is a combination of endless points joined on both sides of a point.''
Given, two points are (5, 11) and (14, -10).
Let, the line that passes through both these points has a slope = m.
Where, m = [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex].
Here, (y₂ - y₁) = Change in the value of y.
(x2 - x₁) = Change in the value of y.
Therefore, [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex] = [tex]\frac{-10 - 11}{14 - 5}[/tex] = [tex]\frac{-21}{9}[/tex] = [tex]\frac{-7}{3}[/tex]
Hence, slope of the straight line is [tex]\frac{-7}{3}[/tex].

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options. The amount of change is different for the percent increase and the percent decrease. The ratio of the percent increase is not the same as the percent decrease. The ratio for the percent increase has a smaller denominator than the percent decrease. The ratio for the percent increase has a different numerator than the percent decrease. The original amount for the percent increase is different from the original amount for the percent decrease.

(A) The amount of change is different for the percent increase and the percent decrease.
(C) The ratio for the percent increase has a smaller denominator than the percent decrease.
(D) The ratio for the percent increase has a different numerator than the percent decrease.
Percentage:A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.Example -An increase of $[tex]0.15[/tex] on a $[tex]2.50[/tex] price equals a fractional increase of [tex]\frac{0.15}{2.50} =0.06[/tex]. This represents an increase of % when expressed as a percentage.There is no mathematical restriction, therefore percentages may have various values even though the majority of % numbers fall between [tex]0[/tex] and [tex]100[/tex]. For percent changes and comparisons, it's typical to use terms like [tex]111[/tex] percent or [tex]35[/tex] percent.Therefore, the correct options are as follows -
(A) The amount of change is different for the percent increase and the percent decrease.
(C) The ratio for the percent increase has a smaller denominator than the percent decrease.
(D) The ratio for the percent increase has a different numerator than the percent decrease.

Jade takes 5 minutes more than twice as long as Binh to ride to their friend’s house. If Binh takes x minutes to ride to his friend’s house, how long will it take Jade?
Answers
Answer:
It will take Jade (2x + 5) minutes
Step-by-step explanation:
Let us find the expression that represents the time Jade will take
∵ Binh takes x minutes to ride to his friend’s house
∴ The time Binh takes = x minutes
∵ 5 more means + 5
∵ Twice means × 2
∵ Jade takes 5 minutes more than twice as long as Binh to ride to their
friend’s house
→ Multiply the time Binh takes by 2 and add the product by 5
∵ Binh takes x minutes
∴ The time Jade takes = 2 × x + 5
∴ The time Jade takes = 2x + 5 minutes
∴ It will take Jade (2x + 5) minutes
Find the mean, variance and standard deviation of the binomial experiment. In a recent survey, 70% of the community favored building a police substation in their neighborhood. If 30 citizens are chosen, what is the mean number favoring the substation? What would be the variance and standard deviation of their responses?
Answers
Answer: Mean = 21 , Variance = 6.3 , standard deviation =2.51
Step-by-step explanation:
Formula for the mean, variance and standard deviation of the binomial experiment :
[tex]Mean = np\\\\ Variance = np(1-p)\\\\ Standard\ deviation = \sqrt{variance}[/tex]
, where n= sample size , p= population proportion.
As per given, p= 70%=0.7 , n=30
[tex]Mean = 0.7\times30=21\\\\Variance =(30)(0.7)(1-0.7)=(21)(0.30)=6.3\\\\ Standard\ deviation = \sqrt{6.3}\approx2.51[/tex]
Hence, Mean = 21 , Variance = 6.3 , standard deviation =2.51

Students plan to pay back half the debt now though fundraising, and the rest after the harvest. Write an equation to represent the debt they will repay through fundraising. Use a negative integer to show debt. Use "D" to represent the debt that will be repaid by through fundraising
Answers
Answer:
D = [tex]\frac{-d}{-2}[/tex]
Step-by-step explanation:
The amount of money that the students will pay back with the fundraiser (D) would be half of the current debt (d) since debt is represented as a negative but the fundraiser needs to be a positive since it is money gained we would divide by -2
D = [tex]\frac{-d}{-2}[/tex]
This equation shows the debt that will be repaid through the fundraiser which would be exactly half of the current debt.

A train company moves people between Boston and Providence every day. They travel from city to city 7 times each day. The distance between the two cities is 48 miles. In February, there are 28 days. The company's budget allows for 15,000 total miles in February. Do you think the budget is reasonable? Explain.
Answers
Answer: the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget
Step-by-step explanation:
Given data:
Distance between two cities = 48 miles
Number of days available in February = 28
February budget = 15000 miles
Solution:
If the distance between two cities = 48 miles, and 7 trips are made daily
= 48miles * 7
= 336 miles is travelled each day.
For February
= 28days * 336
= 9408 miles.
Budget – travel distance covered ( February)
= 15,000 - 9408
= 5592 miles.
The budget is reasonable because, by following the travel pattern or history the total travelled miles would be 9408 miles for February which is below the budget allowed by the company for the month.
So the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget.

Connor says that the graph shows that water is flowing at a rate of 2 gallons per minute. Is he correct?
a. Connor is correct because the rate of water flowing is equal to the slope. Water is flowing in at a rate which is about 2 gallons per minute.
b. Connor is not correct because the rate of water flowing is greater than the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
d. Connor is correct because the rate of water flowing is less than the slope. Water is flowing in at a rate which is faster than 2 gallons per minute.
Answers
Answer:
Part A: ½
Part B: c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
Step-by-step explanation:
Part A:
Slope of the proportional graph = y/x
Using the point on the line, (4, 2),
Slope = 2/4 = ½.
Part B:
Since the slope of the graph bus ½, it shows that the water is flowing at a rate of ½ gallon per minute. Therefore, Connor is NOT CORRECT.
The rate of water Connor stated does not correspond with the rate shown by the slope. The slope of the graph, ½, shows that the water is flowing at a much slower rate than at the rate of 2 gallons per minute, which Connor stated.
The right answer is C.
