The scatter plot shows the relationship between the test scores of a group of students and the number of hours they study in a week.
Part A: What is the group of points labeled N called? What is the point labeled M called? Give a possible reason for the presence of point M.
Part B: Describe the association between students’ test scores and the number of hours they study.
Answer:
Step-by-step explanation:
m is called an outlier and it is a positive association
Answer:
Part A) Part N.) is called the cluster of the whole chart. Part M.) is called the outlier because it's not with the rest of the group, therefore, it's the outlier of the group.
Part B.)
The association between the students' test scores and the number of hours they've studied is a positive correlation. That means the longer the students spent time studying for their tests... the better grades they got because of it. It's a lot like a cause-and-effect kind of situation.

High blood pressure has been identified as a risk factor for heart attacks and strokes. The National Health and Nutrition Examination Survey reported that the proportion of U.S. adults with high blood pressure is 0.3. A sample of 38 U.S. adults is chosen. (a) Is it appropriate to use the normal approximation to find the probability that more than 40% of the people in the sample have high blood pressure? If so, find the probability. If not, explain why not. (b) A new sample of 80 adults is drawn. Find the probability that more than 40% of the people in this sample have high blood pressure.

Triangle DEF has side lengths e=9 and f=13. If the measure of angle D is 41°, what is the length of side d?
• 13.5
• 5.1
• 6.9
• 8.6
Answer:
8.6
Step-by-step explanation:
Use the law of cosines
[tex]d^{2} = e^{2} + f^{2} -2ef cos D[/tex]
[tex]d^{2} = 9^{2} + 13^{2} - 2(9)(13) cos 41\\ = 81 + 169 - 176.602\\ = 73.3979\\d = \sqrt{73.3979} = 8.6[/tex]

How far does she walk around the pool every morning? *
70.65
141.3
35.33
282.6
Answer:
Total walk she did around the pool every morning = 141.3
Step-by-step explanation:
Given - Kriti has a circular swimming pool in her house. The radius of the swimming pool is 22.5 cm. She walks one round every morning before diving in the pool.
To find - How far does she walk around the pool every morning?
Proof -
Given that, the swimming pool is circular in shape.
So,
1 round of circle = Circumference of circle.
As we know that,
Circumference = [tex]2\pi r[/tex]
= [tex]2*\pi *22.5[/tex]
= 141.3
∴ we get
Total walk she did around the pool every morning = 141.3

Step-by-step explanation:
The given quadratic equation is in standard form. Standard form is the basic format of representing a quadratic equation, a quadratic equation in standard form would use the following format,
[tex]y=ax^2+bx+c[/tex]
To solve this problem, one could use Vieta's theorems. Vieta's theorems state the following, let ([tex]x_1[/tex]) and ([tex]x_2[/tex]) represent the roots of the equation,
[tex](x_1)+(x_2)=-\frac{b}{a}[/tex]
[tex](x_1)(x_2)=\frac{c}{a}[/tex]
Substitute the given values into the equation,
[tex]3+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=\frac{24}{3}[/tex]
Simplify,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=8[/tex]
Inverse operations,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex]x_2=\frac{8}{3}[/tex]
Substitute in the value of ([tex]x_2[/tex]),
[tex](3)+(\frac{8}{3})=-\frac{b}{3}[/tex]
Simplify, convert to improper fractions and combine like terms,
[tex]\frac{9}{3}+\frac{8}{3}=-\frac{b}{3}[/tex]
[tex]\frac{17}{3}=-\frac{b}{3}[/tex]
Multiply both sides of the equation by ([tex]3[/tex]) to remove the denominator,
[tex]17=-b[/tex]

You bet $7 on a local race being held for charity. The payoff odds given by the charity event are 12:1. Find your net profit for winning your bet in the race.
$74
$84
$91
$80
Answer:
$84
Step-by-step explanation:
12:1 means for every dollar you bet you will win 12
so 7 x 12 = 84
you would win $84, you bet 7 so net profit would be 84-7 = $77
Net profit is $77

Suppose the function:
f(x) = 2.9646 (1.0170)x
models the world population x years after 1948.
Rewrite the exponential equation given above using base e.
f(t) = 2.9646 e ^(0.0169) t
B.
f(t) = 2.9646 (1.0170) e^t
C.
f(t) = 2.9646 + 1.0170e^t
D.
f(t) = 2.9646 e^(1.0170t)
E.
f(t) = 2.9646 e^ln (1.0170t)
Given:
The function is:
[tex]f(x)=2.9646(1.0170)^x[/tex]
To find:
Rewrite the exponential equation given above using base e.
Solution:
The exponential models is:
[tex]f(x)=P(1+r)^x[/tex] ...(i)
Where P is initial values, r is the rate of interest and x is the time period.
The exponential models using base e is:
[tex]f(t)=Pe^{rt}[/tex] ...(ii)
Where, P is initial values, r is the rate of interest and t is the time period.
The given function is:
[tex]f(x)=2.9646(1.0170)^x[/tex]
It can be written as:
[tex]f(x)=2.9646(1+0.0170)^x[/tex] ...(iii)
On comparing (i) and (iii), we get
[tex]P=2.9646[/tex]
[tex]r=0.0170[/tex]
Putting [tex]P=2.9646[/tex] and [tex]r=0.0170[/tex] in (ii), we get
[tex]f(t)=2.9646e^{0.0170t}[/tex]
Therefore, the correct option is D.

The value of the missing number x will be 10.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Let the missing number be x. Then the equation can be written as,
3 + 7 + 2 = x + 2
Simplify the equation, then the value of the variable x will be
3 + 7 + 2 = x + 2
3 + 7 + 2 - 2 = x
x = 3 + 7
x = 10
The value of the missing number x will be 10.

5(2x - 8) - 15 = 5
Show/Write the steps you would use to solve the equation.
Answer:
x=6
Step-by-step explanation:
Solve for x:
5 (2 x - 8) - 15 = 5
5 (2 x - 8) = 10 x - 40:
10 x - 40 - 15 = 5
Grouping like terms, 10 x - 40 - 15 = 10 x + (-40 - 15):
10 x + (-40 - 15) = 5
-40 - 15 = -55:
10 x + -55 = 5
Add 55 to both sides:
10 x + (55 - 55) = 55 + 5
55 - 55 = 0:
10 x = 5 + 55
5 + 55 = 60:
10 x = 60
Divide both sides of 10 x = 60 by 10:
(10 x)/10 = 60/10
10/10 = 1:
x = 60/10
The gcd of 60 and 10 is 10, so 60/10 = (10×6)/(10×1) = 10/10×6 = 6:
Answer: |
