Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.

which coordinate is a solution to the equation: 7x + 4y = 9?
a (4, -2)
b. (-33)
c. (3-3)
d. (-4,2)
Answer:
C. (3,-3)
Step-by-step explanation:
7 ( 4) + 4 (-2) = 9 false
7 ( -3) + 4 (3) = 9 false
7 ( 3) + 4 ( -3) = 9 true
7 ( -4) + 4 ( 2) = 9 false

Find an equation for each line:
Line ℓ: y =
Line m: y =
Line n: y =
Line p: x =
If you helped, thank you so much, you are an amazing person <3
Line P: x = -4
Line n: y = x -1
Line m: y= -2x + 4
Line l: x = 4
No problem =)
The equation of the lines are,
Line ℓ: y = 4
Line m: y = -2x + 4
Line n: y = x - 1
Line p: x = -4
What is a line?A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
From the map,
Locate at least 1 point in every line to define the equation of line,
Consider line l,
Now, on the y-axis line l passes through (0, 4),
Standard equation of the line,
y = mx + c,
Since the slope of the line l is zero and the y-intercept is 4, so the equation is,
y = 0(x) + 4
y = 4
Similarly, the equation of the other line is givens,
Line m
y = -2 + 4 (slope is -2 and y-intercept is +4)
Line n,
y = x - 1 (slope is 1 and y-intercept is -1)
Line p
x = -4 (slope is 1/0 and y-intercept is 0)
Thus, the equation of the line is shown above.

Answer:
.
Step-by-step explanation:
Uses a distributive property to rewrite the expression as a multiple of a sum of two numbers with no common factor 27+9
Given:
The expression is
[tex]27+9[/tex]
To find:
The expression as a multiple of a sum of two numbers with no common factor.
Solution:
We have,
[tex]27+9[/tex]
It can be written as
[tex]=3\times 9+9[/tex]
Using distributive property taking out the common factors.
[tex]=(3+1)9[/tex] [tex][\because a(b+c)=ab+ac][/tex]

Solving inequality
Answer:
x _> 9 I dont have the symbol on my phone so I just put the greater than sign there
Step-by-step explanation:
1. Subtract 3 from both sides
5x > 48 - 3
2. simplofy 48 - 3 to 45
5x > 45
3. Divide both sides by 5
x > 45/5
4. Then simplify 45/5 to 9 which gives us the answer
And again I dont have the sign thats why I used the greater than sign

Answer:
H(35)=50-75/5
Step-by-step explanation:
75/5=15
50-15=35
Answer:
h(35)=43
Step-by-step explanation:
You just need to replace the t with 35. So you get the equation of 50-35/5. This is simplified to be 50-7 which is 43. So your final answer is 43.
36 students signed up to volunteer for a race two or three equal groups of students and each group had a different task how many students were in each group
Answer:
I two groups are formed: 18 students
If 3 groups are formed: 12 students
Step-by-step explanation:
We will answer this problem based on two occurrences:
1. The students chose to form only two groups:
If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.
2. The students chose to form three groups:
If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.

Someone please help me with this question I'm struggling
[tex]g(x) = - 2x + 1 \\ 5 = - 2x + 1[/tex]
Solve for the x-term.
[tex]2x = - 5 + 1 \\ 2x = - 4 \\ x = \frac{ - 4}{2} \\ x = \frac{ \cancel{ - 4} \: \: \: - 2}{ \cancel{2} \: \: \: 1} \Longrightarrow \: \frac{ - 2}{1} \\ x = - 2[/tex]
Answer Check
Substitute x = -2 in the equation.
[tex]5 = - 2( - 2) + 1 \\ 5 = 4 + 1 \\ 5 = 5[/tex]
The equation is true. Therefore x = -2 is the answer.

A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?
a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.
d. No, these horses must be genetically prone to having female offspring
Answer:
A. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
Answer:
(A) No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.

priya bought x grams of flour Clara bought 3/8 more than that select all questions that represent the relationship between the amount of flour prior bought x and the amount of flour Clara bought is y
a. y = 3/7 c
b. y = 5/8 x
c.y = x + 3/8 x
d. y= x - 3/8 x
e. y = 11/8 x
Answer:
Option C : [tex]x+\frac{3}{8}x[/tex] is the correct answer.
Step-by-step explanation:
Given that:
Quantity of flour bought by Priya = x grams
Quantity of flour bought by Clara = 3/8 more than that
It means that Clara bought the amount bought by Priya plus an additional 3/8 of flour that was bought by Priya
Total bought = y
y = x + [tex]\frac{3}{8}x[/tex]
Hence,
Option C : [tex]x+\frac{3}{8}x[/tex] is the correct answer.

Mary draws the number line below to represent the solution set of the inequality 50 – 8t < 90. What mistake did Mary make? Use the drop-down menus to explain your answer.
Picture relating to question is attached below
Answer:
t > - 5
Line is in the wrong side
Step-by-step explanation:
Given the inequality :
50 – 8t < 90
-8t < 90 - 50
-8t < 40
-8t / - 8 < (40/ - 8)
t > - 5 (sign changes)
During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right

A skin care company had 1,500 people try a new acne cream. Nine people had a mild reaction the formula is then improved and those 1,500 people try the new cream only 4
Answer:
The percent decrease in number of allergic reactions is 55%
Step-by-step explanation:
Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?
Percent of allergic people= Allergic people/ Total people * 100
= 9/1500* 100
= 0.6 %
IT means that out of 1000 people only 6 persons are allergic to the cream.
New Percent of allergic people= Allergic people/ Total people * 100
= 4/1500* 100
= 0.267 %
It means that out of 1000 people only 2.67 persons are allergic to the new improved cream.
Difference between Percentage = Old Percentage- New Percentage
= 0.6 %- 0.267%
=0.333%
Decrease= 0.333% = 0.333/100
In every thousand people 3.33 people are free of allergic reactions from those 6 allergic people.
Percentage Decrease= Decrease/ Total * 100
= 0.333/ 0.6 *100
= 0.55*100
= 55 %
The percent decrease in number of allergic reactions is 55%
