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

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 %

Answer:

0.06 (6%)

13.31

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)

Answer:

TR = 24 units

Step-by-step explanation:

Given 2 secants from an external point to a circle, then

The product of the external part and the whole of one secant is equal to the product  of the external part and whole of the other secant, that is

3x(3x + 5x) = 8(8 + 19)

3x × 8x = 8 × 27

24x² = 216 ( divide both sides by 24 )

x² = 9 ( take the square root of both sides )

x = ± [tex]\sqrt{9}[/tex] = ± 3

but x > 0, thus x = 3

Thus

TR = 8x = 8 × 3 = 24

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

Step 2: Subtract 3x from both sides.

Step 3: Subtract 1 from both sides.

Let's solve your equation step-by-step.

1/3 (9x+3)=3x+1

Step 1: Simplify both sides of the equation.

1/3(9x+3)=3x+1

(1/3)(9x)+(1/3)(3)=3x+1(Distribute)

3x+1=3x+1

Step 2: Subtract 3x from both sides.

3x+1−3x=3x+1−3x

1=1

Step 3: Subtract 1 from both sides.

1−1=1−1

0=0

The following two terms of an arithmetic progression are -6 and -11.

What is an arithmetic sequence?

An arithmetic sequence is defined as a progression of numbers such that the difference between successive terms is consistent. It is also called Arithmetic Progression. The formula for tthe last term of an AP is given as: an = a + (n-1)d, here, a is the first term, n is the number of terms and d is the difference between two successive terms.

Finding the two terms of an arithmetic sequence

The first three terms of an arithmetic sequence are given by:

a1 = 9

a2 = 4

a3 = -1

Now, we want to calculate a4 and a5

Using the formula for calculating the next term of an arithmetic progression, we get,

a4 = a + (n-1)d, where n = 4 and d = 5

a4 = 9 + (4-1)(-5)

a4 = 9 - 15

a4 = -6

Further, a5 = a + (n-1)d, where n = 5 and d = 5

a5 = 9 + (5-1)(-5)

a5 = 9 - 20

a5 = -11

Hence, the next two terms of an AP are -6 and -11.

ppl are wierd that's why I'm an attack helicopter....

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 =

= -20az² - 4a³ + 11a²z

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.

I hope this helped :)

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.

Answer:

Step-by-step explanation:

took the test

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%.
