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.

Answer:

so m=2 so y=2x+-3

Step-by-step explanation:

The linear function rule is y = x + 16

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

Answer:

  9.22

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Using the given coordinates, the distance between them is ...

  d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22

The length of AB is about 9.22 units.

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)

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.

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.

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.

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:

Silas spent $84 of his money to buy a birthday gift for his grandma. Therefore, he has the following amount:

Raja was awarded $42 for winning a competition. Therefore, Raja amount is as follows;

In the end, they had the same amount of money. Therefore,

3x - 84 = x + 42

3x - x = 42 + 84

2x = 126

x = 126 / 2

x = 63

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

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.

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.

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.

Step-by-step explanation:

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
