Which type of association does the scatter plot show?
Answer:
Both positive and negative linear association, or nonlinear association.
Step-by-step explanation:
When a scatter plot has a negative linear association, the points are arranged in a line that is angled in a downward slope. Hence, the word "negative" which refers to "decline"
When a scatter plot has positive linear association, the points are arranged in a line that is angled in a upward slope. Hence, the word "positive" which refers to "incline"
The graph you have has a steep incline, then a steep decline, which indicates that both positive and negative linear association are present, except another option might be nonlinear association.
I have attached a picture below that shows the different types of association in scatter plots.

Pancho saved $1250 over the year from a part time job. He decided to take $850 of it to the bank
where it will earn 1.5% interest. How much interest will he earn if he leaves it there for 2 years?
Answer:
Pancho will earn $25.50 interest.
Step-by-step explanation:
interest= prt (principal x rate x time)
i= prt = 850(.015)(2)
i= 25.5
(.015 comes from dividing the percentage 1.5 by 100)

Element X is a radioactive isotope such that every 14 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 360 grams, how long would it be until the mass of the sample reached 100 grams, to the nearest tenth of a year?
Answer:
25.9 years
Step-by-step explanation:
The half life of an isotope is related to the actual amounts by the equation:
N = Ni*(1/2)^(t/HL)
where N and Ni are the final and initial (Ni) amounts, t is the time (in years for this problem) and HL is the half-life, in years.
In this problem, we can write:
100 = 360*(1/2)^(x/14)
I'll reduce this to:
1 = 3.6*(1/2)^(x/14)
This can be solved by taking the log of both sides.
x = 25.87 or 25.9 years

Krystal left the bookstore traveling 18 mph. Then, 3 hours later, Kori left traveling the same direction at 27 mph. How long until Kori catches up with Krystal
Answer:
Korl will catch up to Krystal in 2 hours.
Step-by-step explanation:
18x3=54 this shows how long Krystal has driven in 3 hours.
27x2=54 this shows that in 2 hours Korl will have driven 5 mph.
Now as you can see both quotient are 54 and the question is How long until Korl catches up to Krystal so it's 2 hours

PZL answer quick!
Answer:
2=5
4=6
6=7
8=8
Step-by-step explanation:
The formula is 4+.5(x)=
So multiply 0.5 by 2 which gives you 1 then add 4 which gives you 5.
To get 6 for 4, you multiply 0.5 by 4 which gives you 2 then add 2+4.
for 6, multiply 0.5 x 6=3 and then 3+4= 7
for 8, multiply 0.5 x 8=4 then add 4+4= 8

is it linear or nonlinear?
Answer:
Nonlinear
Step-by-step explanation:
You can determine if this equation is linear or nonlinear by noticing the squared x, meaning it is a quadratic and it will not be a straight line on the graph, but instead a parabola shape. Linear equations will not have an [tex]x^{2}[/tex] but will have one x.
12% of 80 working out
How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:
To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.
What I mean:
You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal
Then multiply that decimal by the whole
Since you want 12% of 80, 80 is the whole
that means you do .12 * 80
which is equal to 9.6
Thus(answer)
12% of 80 = 9.6

Solve the equation 4(3A-4) = 56 for the variable A.
Show your work.
Answer:
A = 6
Step-by-step explanation:
4(3A - 4) = 56 (Distribute/multiply the 4 to everything inside the parentheses)
12A - 16 = 56 (Add 16 to both sides to get A on one side)
12A = 72 (Divide both sides by 12 to get A by itself)
A = 6
Answer:
A = 6.
Step-by-step explanation:
4(3a-4)=56
distribute
12a-16=56
add 16
12a = 72
divide by 12
a = 6

GivenDoug bought a new car for $25,000.
He estimates his car will depreciate, or lose value, at a rate of 20% per year.
The value of his car is modeled by the equation V = P(1 – r)t,
Where V is the value of the car, P is the price he paid, r is the annual rate of depreciation, and t is the number of years he has owned the car.
What is depreciation?Depreciation is a kind of accounting method that is utilized for the allocation of the physical asset cost in the context of its life expectancy or its usefulness.
The value of his car is modeled by the equation;
[tex]\rm V = P(1 - r)^t[/tex]
Where the value of p = 25,000 and r is 20% = 0.20 and time is er 4 and one-half years = 4.5 years.
Substitute all the values in the formula;
[tex]\rm V = P(1 - r)^t\\\\V = 25000(1-0.20)^{4.5}\\\\V = 25000(0.80)^{4.5}\\\\V = 25000 \times 0.366\\\\V = 9159[/tex]
Hence, the value of his car after 4 and one-half years is $9159.

Step-by-step explanation:
Explain the first step when dividing a fraction by a fraction.
The first step is to change the division operation into multiplication.
When dividing a fraction by another fraction, the first step is to change the division operation into multiplication. This can be done by using the concept of reciprocal or multiplicative inverse.
Reciprocal or multiplicative inverse of a fraction is a fraction that, when multiplied by the original fraction, gives a product of 1. In other words, if we have a fraction a/b, then its reciprocal is b/a.
So, the first step when dividing a fraction by a fraction is to find the reciprocal of the second fraction (the divisor). Let's say we have the fraction a/b divided by c/d. The reciprocal of c/d is d/c.
After finding the reciprocal, the division problem is transformed into a multiplication problem. We can rewrite the expression as follows:
(a/b) ÷ (c/d) = (a/b) × (d/c)
Now, we can multiply the fractions using the multiplication rules for fractions. Multiply the numerators (a and d) to get the new numerator, and multiply the denominators (b and c) to get the new denominator:
(a/b) × (d/c) = (a × d) / (b × c)
This is the first step when dividing a fraction by a fraction. Once you have obtained the product (a × d) / (b × c), you can simplify it further if necessary.

Find the value of d, plz reply asap I just have 5 min left to submit it
Answer:
97 degrees
Step-by-step explanation:
Angle d and the angle to the right of angle c are alternate interior angles. This means that these angles are congruent. The angle next to angle c is equal to 180-83 degrees, which is the same as 97 degrees. So, angle d has a value equivalent to 97 degrees.
