Answer:
We conclude that the price per pound of the grapes = $1.45
Hence, option A is true.
Step-by-step explanation:
Given the table
Pounds of Grapes Total Cost
1.2 $1.74
2.6 $3.77
4.4 $6.38
Total pounds of Grapes = 1.2+2.6+4.4
= 8.2 pounds
Aggregate cost = 1.74 + 3.77 + 6.38
= $11.89
Thus,
Prince per pound = Aggregate cost / Total pounds of Grapes
= 11.89 / 8.2
= $1.45
Therefore, we conclude that the price per pound of the grapes = $1.45
Hence, option A is true.

A circle has a diameter of 18 feet. Which following is closest to the l circumference of the circle?
A-28.3ft
B-56.5ft
C-113.1ft
D-245.5ft
Answers
circumference =2×pi×r
18/2=9(r)
so...2×pi×9
=54..5
Answer:
56.5 ft
Step-by-step explanation:
We define the number π as the ratio between the circumference and diameter of a circle: π = c/d. Rearranging this equation gives us one for the circumference: c = πd. Using an approximation of π ≈ 3.14 and our value of d = 18 feet, we can find that c = 3.14(18) = 56.52 ft, or 56.5 ft, rounded to the nearest tenth.

A flower bed is in the shape of a triangle, with a base of 13 feet and a height of 5 feet. What is the area of the flower bed?
1. 18 square feet
2. 32.5 square feet
3. 65 square feet
4. 130.5 square feet
Answers
Answer:
32.5
Step-by-step explanation:
For triangles you need to do base times height divided by 2
Answer:
Number 2: 32.5 square feet
Step-by-step explanation:
The formula for the area of a triangle is 1/2(base)(height)
In this case, our base is 13 ft and our height is 5 ft so we plug in those values into our formula
A = 1/2(13)(5) = 32.5
Therefore our area is 32.5 square feet.

Answers
Step-by-step explanation:
The Correlation Coefficient
When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation of -0.97 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.

Jack and Jill fetched 24 pints of water in their bucket. Jill drank a tenth of this, jack a quarter. They gave three eighths to dame Dob and a fifth to jill's mother.
Answers
Answer: See explanation
Step-by-step explanation:
Total water fetched = 24 pints.
Jill drank a tenth of this. This will be:
= 1/10 × 24
= 2.4 pints
Jack drank a quarter. This will be:
= 1/4 × 24 = 6.
They gave three eighths to dame Dob . Thus will be:
= 3/8 × 24
= 9
They gave a fifth to jill's mother. This will be:
= 1/5 × 24.
= 4.80
Amount that'll be left over will be:
= 24 - (2.40 + 6 + 9 + 4.80)
= 24 - 22.2
= 1.8
1.8 pints of water will be left over.

Silas had 3 times as much money as Raja. Silas spent $84 of his money to buy a birthday gift for his grandma while Raja was awarded $42 for winning a competition. In the end, they had the same amount of money. How much did they have altogether at first?
Answers
Answer:
Total amount Silas and Raja has at first = $252
Step-by-step explanation:
Let,
Amount Silas had = x
Amount Raja had = y
According to given statement;
x = 3y Eqn 1
x-84 = y+42 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
3y - 84 = y+42
3y-y = 42+84
2y = 126
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{126}{2}\\y=63[/tex]
Putting y = 63 in Eqn 1
x = 63(3)
x = 189
Total amount they had = 189 + 63 = $252
Hence,
Total amount Silas and Raja has at first = $252
The amount they have altogether at first is $252
Let
Raja money = x
Silas had 3 times as much money as Raja. Therefore, Silas money is as follows:
3xSilas spent $84 of his money to buy a birthday gift for his grandma. Therefore, he has the following amount:
3x - 84Raja was awarded $42 for winning a competition. Therefore, Raja amount is as follows;
x + 42In the end, they had the same amount of money. Therefore,
3x - 84 = x + 423x - 84 = x + 42
3x - x = 42 + 84
2x = 126
x = 126 / 2
x = 63
Total amount(at first):x + 3x = 63 + 3(63) = $252learn more on equation here: https://brainly.com/question/228711?referrer=searchResults

No, P(almonds) ≠ P(California|almonds).
No, P(almond) ≠ P(almonds|California).
Answers
Answer:
No, P(almond) ≠ P(almonds|California).
Step-by-step explanation:
In this question, we have that:
38% of adults say that almond is their favorite nut.
Of those adults surveyed, 19% live in California, and of those, 40% chose the almond as their favorite nut.
Since the probabilities are not equal(probability of liking almonds and probability of liking almonds, given that the person lives in California), we have that liking almonds is not independent of residency, and the correct option is:
No, P(almond) ≠ P(almonds|California).
No, P(almond) ≠ P(almonds| Is liking almonds independent of residency.
Given that,
According to a recent survey of adults, 38% say the almond is their favorite nut.
The adults were also asked where they lived.
Of the 19% of those who responded that they live in California, 40% chose the almond as their favorite nut.
We have to determine,

Answers
It’s established that both of these angles are equal to each because they’re vertical equals. With this information we can make the equation 2x + 65 = 8x + 5. We then solve this equation for x.
2x + 65 = 8x + 5
60 = 6x
x = 10
We then plug the value of x into either of the equations for the angles, giving us the answer 85.
Answer:
80˚
Step-by-step explanation:
Since the angles are equal, we can make this equation:
2x + 65 = 8x + 5
60 = 6x
x = 10
so if we put x = 10 in 8x + 5 we get
8x + 5
8(10) + 5
80 + 5
85

Answers
Answer:
one solution, no solution, infinitely many solutions
Step-by-step explanation:
I rearranged the first equation into x=6-2y
plug that into the second equation
2(6-2y)-3y=26
12-4y-3y=26
12-7y=26
-7y=14
y=-2
Then you plug that into one of the equations
x+2(-2)=6
x-4=6
x=10
The solution to the first system is (10,-2)
the second system already has one equation as something equal to a single variable so you just plug that into the other one
4x-2(2x-4)=-6
4x -4x +8 =-6
8=-6
this is a false statement so the system of equation has no solution
Lastly I rearranged the first equation into y=2x-4 and then plug that in
6x-3(2x-4)=12
6x-6x+12=12
12=12
this statement is true so the system of equations has infinite solutions
Solve the following system of equations using substitution or elimination: y = −8x − 9 y = −6x + 5
Answers
Answer:
x = -7
y = 47
Step-by-step explanation:
Given the system of equation
y = −8x − 9 ... 1
y = −6x + 5 ...2
Equating both expressions
-8x - 9 = -6x + 5
Collect like terms
-8x + 6x = 5 + 9
-2x = 14
x = 14/-2
x = -7
Substitute x = -7 into equation 1.
From 1: y = −8x − 9
y = -8(-7) - 9
y = 56 - 9
y = 47
Hence the solution to the system of equations (x, y) is (-7, 47)

What is a Linear equation?
A linear equation is an algebraic equation of the form y = mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given, A line passes through the points (4,20) and (8,24)
From the slope-intercept form of a line:
Y = mx + c
Where,
m = slope = (y₂ - y₁)/ (x₂ - x₁)
c = constant
In our case,
m = (24 -20)/ 8-4
m = 4/4
m = 1
So the equation of a line
y = x + c
Since, this line passes through the point(4, 20)
20 = 4 + c
c = 16
Therefore, the equation of the line passes through the points (4,20) and (8,24) is y = x + 16
