Answer: m= -9

Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9

Answer:

$7.92

Step-by-step explanation:

1 lemon = 2 tbsp = $0.66

1 pie = 1/2 cup

So take 3 x 1/2 = 1 1/2 cups. Now we know that we need 1 1/2 cups of lemon juice. So convert 1 1/2 cups into tbsp and you get 24 tbsp. Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2 and you get 12. This 12 represents the amount of lemons you need to buy. Since 1 lemon is $0.66 take that and multiply it by the amount of lemons you need (12x0.66) now you get $7.92.

You need $7.92 to but 12 lemons to make three 9 inch lemon pies.

The cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice is $7.92

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

1 cup of lemon juice requires around 16 tablespoons of of juice.

1 lemon = 2 tbsp = $0.66

1 pie = 1/2 cup

number of cups = 3 x 1/2 = 1 1/2 cups.

Now we know that we need 1 1/2 cups of lemon juice.  convert 1 1/2 cups into tablespoons and you get 24 tablespoons .

Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2

number of tablespoons = 24/2 = 12.

This represents the amount of lemons you need to buy.

Since 1 lemon is $0.66 take that and multiply it by the amount of lemons number of lemons = (12x0.66) =  $7.92.

WE need $7.92 to but 12 lemons to make three 9 inch lemon pies.

The expected returns is 33.7% and the standard deviations of returns is 38.73%.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.

Now given probabilities are,

probabilities P = 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15

Given returns on the probabilities,

returns r = 50%, 39%, -4%, 20%, -25%, and 42%

So, Expected rate of returns = ∑Pr

⇒ Expected rate of returns = 0.15(50) + 0.34(39) + 0.44(-4) + 0.67(20) + 0.2(-25) + 0.15(42)

⇒ Expected rate of returns = 7.5 + 13.26 - 1.76 + 13.4 - 5 + 6.3

⇒ Expected rate of returns = 33.7%

Now standard deviation S is,

Square root of the difference squared between each value and the mean, multiplied by the probability.

S = √{0.15(50 - 33.7)² + 0.34(39 - 33.7)² + 0.44(-4 - 33.7)² + 0.67(20 - 33.7)² + 0.2(-25 - 33.7)² + 0.15(42 - 33.7)²}

⇒ S  = √{0.15(16.3)² + 0.34(5.3)² + 0.44(-37.7)² + 0.67( - 13.7)² + 0.2(-58.7)² + 0.15(8.3)²}

⇒ S  = √{0.15(265.69)+ 0.34(28.09) + 0.44(1421.29) + 0.67( - 187.69) + 0.2(3445.69)²\ + 0.15(68.89)}

⇒ S  = √{39.85 + 9.55 + 625.36 + 125.75 + 689.13 + 10.33}

⇒ S  = √{1499.97}

⇒ S  = 38.73%

Thus, the expected returns is 33.7% and the standard deviations of returns is 38.73%.

Answer:

the answer is 19.50

Step-by-step explanation:

lets start by by reviewing the problem

bonnie withdrew 1200 dollars

she spend 240 on travel agents

then she spends 640 at the hardware store

so if we add all of that up  we get 880

then we will subtract that from the total of her money

=320 left but we aren't finished

then she spend some money on lunch

so we would subtract 320 from

Answer:

12%

Step-by-step explanation:

Add each number of students in the graph together. 1 + 6 + 2 + 3 = 12, so it's 12%.

Percentage of students who responded to the survey is 48 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The total number of students in the survey = 25 students

The number of students who played Violin = 1 student

The number of students who played Piano = 6 students

The number of students who played Guitar = 2 students

The number of students who played Drums = 3 students

So ,

Total number of students who played instruments =
Number of students who played Violin + Number of students who played Piano + Number of students who played Guitar + Number of students who played Drums

Total number of students who played instruments = ( 1 + 6 + 2 + 3 )

                                                                                    = 12 students

Now ,

Percentage of students who played the instruments = Percentage of students who responded to the survey

And ,

Percentage of students who responded to the survey =
( Total number of students who played instruments / Total number of students in the survey ) x 100

Percentage of students who responded to the survey = ( 12 / 25 ) x 100

                                                                                          = 12 x 4

                                                                                          = 48 %

Therefore , percentage of students who responded to the survey = 48 %

Hence , percentage of students who responded to the survey is 48 %

The total purchase is  $18.90.

A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.

The first step is to determine the total cost of the items purchased.

Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)

(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39

Since, the total cost is greater than $20 she qualifies for the 10% discount

Total cost after the discount = (1 - 0.1) x $20.39

0.9 x $20.39= $18.35

Cost after the tax = (1 + 0.03) x $18.35

1.03 x $18.35 = $18.90

Answer:

an acute an angle

Step-by-step explanation:

the angel of 31 is smaller than 90 so that would make it an acute angle

A 31° angle is an acute angle because it measures less than 90 degrees.

An angle is formed when two straight lines or rays meet at a common endpoint.

We know that a right angle is always equal to 90 degrees.

Any angle less than 90 degrees is an acute angle

Any angle greater than 90 degrees is an obtuse angle.

A 31° angle is an acute angle because it measures less than 90 degrees. An acute angle is any angle that measures between 0 and 90 degrees.

Hence, A 31° angle is an acute angle because it measures less than 90 degrees.

So, 10% were turkey sandwiches

Step-by-step explanation:

if I take the expression as you wrote it literally, we have

(-12az2 - 22³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -24az - 10,648 - 2a³ + 7a²z + 4a²z - 8az² =

= -24az - 10,648 - 2a³ + 11a²z - 8az²

yet when I assume that there were several typos particularly in the first bracket, my guess about the real original expression is

(-12az² - 2a³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -12az² - 2a³ - 2a³ + 7a²z + 4a²z - 8az² =

0.2266

Step-by-step explanation:

1)

Given that :

Probability that it rains on Friday ; P(FR) = 0.8

Probability that it rains on Saturday ; P(SR) = 0.7

P(FR) and P(SR) are independent events

Probability that it does not rain on Friday ; P(FR)' = 1 - P(FR) = 1 - 0.8 = 0.2

Probability that it does not rain on Saturday ; P(SR)' = 1 - P(SR) = 1 - 0.7 = 0.3

Hence, probability that it does not rain on Friday and on Saturday ;

P(FR)' * P(SR)' = 0.2 * 0.3 = 0.06 = 0.06 * 100% = 6%

2)

Given the scores :

82, 73, 61, 97, 83 ;

The sample standard deviation :

Sqrt(Σ(X - m)^2 ÷ n - 1)

n = sample size = 5

m = mean = ΣX / n

m = (82 + 73 + 61 + 97 + 83) / 5 = 79.2

Sqrt((82 - 79.2)^2 + (73 - 79.2)^2 + (61 - 79.2)^2 + (97 - 79.2)^2 + (83 - 79.2)^2) / (5 - 1)

Sqrt(177.2) = 13.311649

Hence, standard deviation = 13.31

3.)

Given that :

Mean(m) = 120

Standard deviation (s) = 20

Probability that randomly taken test taker scores less than 105

P(x < 105)

Obtain the standardized score :

Z = (x - m) / s

Z = (105 - 120) / 20

Z = - 15 / 20

Z = - 0.75

P(Z < - 0.75) = 0.22663 (Z probability calculator)
