Which equation BEST represents the line of best fit for the scatterplot? A) y = x + 2 B) y = x + 1 C) y = x - 2 D) y = 2x + 1
Answers
Answer:
y=x+2 is the right answer
Step-by-step explanation:
Equation A best represents the line of best fit for the scatter plot. Option A is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
From option 1;
y= x+2
At,x=0 y=2
At,y=0 x=-2
The equation satisfy the graph in the best possible way. So that equation A best represents the line of best fit for the scatter plot.
Hence, option A is correct.

If Jamal borrowed $625 from his brother for 8 years and later paid $830 then he must have taken it at the simple rate of 4.1%.
What is simple rate of interest?The interest which is not calculated on the aggregate interest or which is calculated only on principal amount is known as simple interest.
How to determine rate of interest?The principal amount is $625 and the number of years is 8 and we have to find the rate of interest.
The amount which is ultimately paid is equal to principal and interest. So,
830=625+625*r/100*8
830-625=625*r/100*8
205=625*r/100*8
205*100/625*8=r
20500/5000=r
r=4.1%
Hence if the principal amount is $625 and the amount lastly paid is $830 then the rate of interest is 4.1% which is option B.

Multiply. (2x+1)(x−5) Express the answer in standard form. Enter your answer in the box
Answers
Given is (2x+1)(x−5)
We need to multiply the binomials and write the expression in standard form.
We know about distributive property that is given as "a(b+c) = ab + ac".
We have (2x+1)(x−5).
Step 1: Using Distributive property on first binomial expression (2x+1).
2x(x-5) + 1(x-5)
Step 2: Using Distributive property on second binomial expression (x-5).
2x(x) + 2x(-5) + 1(x) + 1(-5)
2x² - 10x + 1x - 5
Step 3: Combining like terms.
2x² - 9x - 5
Hence, final answer is (2x² - 9x - 5).

3. The area of a triangle can be given by (just plug and chug as always):
[tex]A_t = \frac{1}{2} bh = \frac{1}{2}(3)(4) = 6ft^2 [/tex]
The area of the triangle is 6ft².
4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):
[tex]A_t = \frac{1}{2} bh = \frac{1}{2}(8)(3) = 12m^2[/tex]
[tex]A_r = bh = 12(8) = 96m^2[/tex]
Now we just add them:
[tex]96+12 = 108m^2[/tex]
So, the area of that pentagon is 108m².
5. You are actually wrong on this one because the area of a triangle is:
[tex]A_t = \frac{1}{2}bh [/tex]
So, just halve your answer and it will be correct.
6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:
[tex]A_t = \frac{1}{2}bh = \frac{1}{2}(2.5)(5) = 6.25cm^2 [/tex]
Multiply by 4 to get total area:
[tex]6.25*4 = 25cm^2[/tex]
So, the area of the given rhombus is 25cm².

There is a one time fee of $27 to join the gym the monthly cost of using the gym is $18 write any Quezon for the relationship that gives the total cost Y in dollars of joining the gym and using it for X months
Answers
y represent the total cost
18 represents the cost per month
x represent the number of months
27 is the initial fee
The total cost Y in dollars of joining the gym and using it for X months can be determined using the linear equation Y = 27 + 18X, where 27 is the one-time joining fee, and 18X is the cost of using the gym for X months.
Explanation:To determine the total cost Y in dollars of joining the gym and using it for X months, you would need to consider both the one-time joining fee and the recurring monthly cost. The one-time joining fee is $27 and the monthly cost is $18.
So, if you are going to gym for X months, the total cost will be the sum of the initial joining fee and the monthly cost times the number of months you are going. This relationship can be represented by a linear equation:Y = 27 + 18X.
In this equation, Y represents the total cost of joining and using the gym for X months. The 27 is the one-time joining fee and the 18X represents the total cost of the monthly fees for X months.

how do you solve x/2-x/4=6
Answers
[tex] \frac{x}{2} - \frac{x}{4} = 6[/tex]
To get rid of the fractions you have to multiply by 4. Multiplying by 2 does not work, because of we do that, we can't get rid of x / 4. Hence, multiply the entire function by 4
[tex]4 \times \frac{x}{2} - 4 \times \frac{x}{4} = 6 \times 4[/tex]
[tex]2x - x = 24[/tex]
[tex]x = 24[/tex]
Therefore, the solution to this equation is x = 24. We've found this solution by multiplying the entire function by 4 and then we've collected terms.

The heart rates for puppies are normally distributed, with a mean heart rate of 180 beats
per minute (60-160 beats per minute for most adult dogs) with a standard deviation of 6
bpm (beats per minute).
a. What percentage of puppies will have heart rates of less than 187 bpm?
b. What percentage of puppies will have heart rates between 170 bpm and 187 bpm?
c. If 500 puppies are examined, how many would you expect to have a heart rate of less
than 187 bpm?
d. 10% of all puppies will have a heart rate greater than what value?
Answers
a. The % less than 187 are all, including and less than, +1s. So 50% + 34.1% (1s) = 84.1% of the puppies
b. The % between 170 and 187 would be between -1.5s and +1s. So (34.1% × 2) + (13.6/2) = 68.2% + 6.8% = 75% of the puppies
c. Since in a) we said that the % for less than 187 bpm was 84.1%, we just take that % of 500: .841×500 = 420.5, so we'd expect between 420 and 421 puppies
d. 10% of all.puppies will have a heart rate greater than? This is asking what deviation above the mean corresponds to 10%.
This will be around those above around +1.5s, so around 188 bpm

Jim is painting the inside of a circular helicopter pad. How many cans of paint would he need if the pad is 50 feet across and each can of paint covers about 200ft^2?
Please add how you got your answer and thank you very much!
Answers
You need to find the area of the circular pad.
Circle Area= πr^2
we need the radius which is half of the diameter given
=π(50÷2)^2
=(3.14)(25)^2
=(3.14)(625)
=1,963.495 ft^2 total area
STEP 2:
Find how much paint is needed by dividing a can's coverage into what's needed.
=1963.495 ÷ 200
=9.817
=10 cans are needed (because you cannot buy a part of a can, you need to round up)
ANSWER: 10 cans are needed
Hope this helps! :)
Final answer:
To find out how many paint cans Jim needs, calculate the area of the circular pad using the formula πr^2 and divide by the coverage area of one can. For a 50 feet diameter pad, Jim would need approximately 10 cans of paint.
Explanation:
To calculate the number of paint cans needed, we first need to find the area of the circular helicopter pad. The diameter of the pad is given as 50 feet, so the radius is half of that, which is 25 feet. The area A of a circle is calculated using the formula A = πr^2, where r is the radius.
Substituting the radius into the formula gives:
A = π(25 feet)^2
A = 3.14159 × (25 feet) × (25 feet)
A = 3.14159 × 625 feet²
A = 1963.495 feet²
Since each can covers about 200 square feet, we divide the total area by the coverage area per can:
Number of cans = 1963.495 feet² / 200 feet²/can
Number of cans ≈ 9.82 cans
Since Jim cannot buy a fraction of a can, he would need to round up, meaning he would need 10 cans of paint to cover the helicopter pad.
