Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.
And your answer is 2 out of 10 tosses.

A tall building casts a shadow that is 250 feet long. A nearby person is 6
feet tall, and casts a shadow that is 8 feet long. How tall is the building?*
200 feet
180 feet
192 feet
187.5 feet
Answer:
The building is 187.5 feet tall.
Step-by-step explanation:
A nearby person is 6 feet tall, and casts a shadow that is 8 feet long.
This means that the relation between the real height and the shadow is given by:
[tex]\frac{6}{8} = \frac{3}{4}[/tex]
A tall building casts a shadow that is 250 feet long. How tall is the building?*
The real height is three fourths of the shadow. So
[tex]\frac{3}{4}*250 = 187.5[/tex]
The building is 187.5 feet tall.
Which correlation coefficient represents a weak, positive linear relationship?
Select one:
a. r = 0
b. r = 0.35
c. r = −0.35
d. r = 0.94
e. r = −0.94
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.

x + 2y = 6

y = 2x − 4
2x − y = 4
6x − 3y = 12
Select whether each system of equations has no solution, one solution, or infinitely many solutions.
No Solution

Infinitely Many Solutions
x + 2y = 6
2x − 3y = 26
4x − 2y =−6
y = 2x − 4
2x − y = 4
6x − 3y = 12
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
find two numbers if there sum is 7.2 and their difference is 2.7
Answer:
2.25 and 4.95
Step-by-step explanation:
x + y = 7.2
x - y = 2.7
x = 7.2 - y
x - y = 2.7
(7.2 - y) - y = 2.7
7.2 - 2y = 2.7
-2y = 2.7 - 7.2
-2y = -4.5
-2y/-2 = -4.5/-2
y = 2.25
x + y = 7.2
x + 2.25 = 7.2
x = 7.2 - 2.25
x = 4.95
Check: 4.95 and 2.25
x + y = 7.2
(4.95) + (2.25) = 7.2
7.2 = 7.2
x - y = 2.7
(4.95) - (2.25) = 2.7
2.7 = 2.7
Answer:
x+y=7.2
x-y=2.7
Step-by-step explanation:
equation
x+2.7+x=7
2x=4.3
x=4.3/2

Is liking almonds independent of residency?
Yes, P(almonds) = P(California|almonds).
Yes, P(almonds) = P(almonds|California).
No, P(almonds) ≠ P(California|almonds).
No, P(almond) ≠ P(almonds|California).
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,
Is liking almonds independent of residency.
According to the question,
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.
An independent event and probability, the outcomes in an experiment are termed as events. Ideally, there are multiple events like mutually exclusive events, independent events, dependent events, and more.
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 almond is not independent of residency.
Hence, No, P(almond) ≠ P(almonds| Is liking almonds independent of residency.

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
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.
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?
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

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.
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.
2x+4y=22
-x=2y-11
does it have no solution?
Answer:
No, it actually has infinite solutions.
Step-by-step explanation:
2x+4y=22 is your 1st equation
-x-2y=-11 is your 2nd equation.
Let's say you want to cancel out the x variable. Multiply the 2nd equation by 2.
Then your equations would be:
2x+4y=22
-2x-4y=-22
If you add both you will get 0=0
Since both sides are equal to each other, there are infinite solutions.

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

What is the surface area of the right prism given below?
A. 456 units2
B. 504 units2
C. 552 units2
D. 912 units2
Answer:
B. 504 units²
Step-by-step explanation:
We multiply 6 and 8, we don't need to divide by 2 since there are two congruent triangles. That gets us 48. Now, we multiply 19 and 8. That gets us 152. Now, we multiply 6 and 19. That gets us 114. We have found the area of all sides but one. To do this one, we need to calculate the hypotenuse of the triangle. The following screenshot has the formula to calculate hypotenuse. If a is equal to 6, and b is equal to 8, we can do this formula. 6² is 36, and 8² is 64. Now, we add 36 and 64. That gets us 100. The square root of 100 is 10. That means the hypotenuse of this triangle is 10. Now, we multiply 10 and 19 to get 190. Now, we add up the area of all the sides (48 + 152 + 114 + 190). That gets us 504. That means B is our answer.

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.
