Answer:

37.5%

Step-by-step explanation:

Given data

Initila Price= $2.25

3.5% of  $2.25

=3.5/100* 2.25

=0.035*2.25

=0.07875

Hence the expected new price is

=0.07875+2.25

=$2.33

The expected increase

=2.33-2.25

=$0.08

The actual increase

=2.25-2.30

=$0.05

Hence the error is

% error= Actual -Expected/Expected*100

% error= 0.05-0.08/0.08*100

% error= 0.03/0.08*100

% error=0.375*100

% error=37.5%

Hence the error is 37.5%

Answer:

D. right angle

Step-by-step explanation:

I think D is because

right angle is a an angle of exactly 90°

*adjacent angle is two angles with a common vertex, sharing a common side and no overlap

*supplementary angle is two angle, the sum of who's measure is 180

* vertical angle is two angle who's sides form two pairs of opposite rays (straight line)

Answer:

$14.00

Step-by-step explanation:

First take $20 and divide by 100. Then you multiply by 30 to get the reference which was $6. If the sweatshirt was $20 and the reference was $6, you would subtract $20 - $6 and get $14.

Answer:

Not 95%

Step-by-step explanation:

The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Given that the age of the tree is normally distributed. Also, the following details are known,

Standard Deviation, σ = 10 years

Mean, μ = 40

Now, the z-score and the p-values for the value of 70 and 10 can be written as,

Z = (X-μ)/σ

Z = (70 - 40)/10

Z = 3

The p-value for z-score of 3 is 0.9987.

Z = (X-μ)/σ

Z = (10 - 40)/10

Z = -3

The p-value for z-score of -3 is 0.0013.

Further, the percentage of the trees have ages between 10 years and 70 years is,

Percentage = 0.9987 - 0.0013

                   = 0.9974

                   = 99.7%

Hence, About 99.7% of the trees have ages between 10 years and 70 years.

Answer:

C

Step-by-step explanation:

Sine: Opposite / Hypotenuse

Cosine: Adjacent / Hypotenuse

Tangent: Opposite / Adjacent

75 = The adjacent of 40

H = The opposite of 40

Tan40 = 75 / h

H = 75Tan40

H ≈ 62.93

The trigonometric function which will be used to determine the height of the tree when the base is 75 ft. is tan(40)

The trigonometric function are the ratio of the sides of the right angled triangle. The functions are sine, cos, tan , cot, cosecant, secant.

We can easily see that the base is 75 ft. and the height of the tree is h So the height of the tree can be found with the help of tangent function.

tan(40)=h/75

0.84=h/75

h=63 ft.

Hence the height of the tree is 63 ft.

Answer: 17.75 pounds

Step-by-step explanation:

After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds

Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds

Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds

The number of pounds of soil that they put in the first flower bed altogether will be:

Step-by-step explanation:

you should know that the sum of interior angles of a hexagon is 720 so

[tex]4x - 10 + 2x + 8 + x - 12 + 7x + 3x + 135 = 720 \\ 17x = 121 \\ x = \frac{121}{17} = 7.11764[/tex]

Answer:

It can not be modeled by a linear function

Step-by-step explanation:

The given parameters can be represented as:

[tex](x_1,y_1) = (1,64)[/tex]

[tex](x_2,y_2) = (2,32)[/tex]

[tex](x_3,y_3) = (3,16)[/tex]

Where: x = rounds and y = players

Required:

Determine if it can be represented by a linear function

To do this, we simply calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

and

[tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex]

Using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex], we have:

[tex]m = \frac{32 - 64}{2 - 1}[/tex]

[tex]m = \frac{-32}{ 1}[/tex]

[tex]m = -32[/tex]

Using [tex]m = \frac{y_3 - y_2}{x_3 - x_2}[/tex], we have:

[tex]m = \frac{16 - 32}{3 - 2}[/tex]

[tex]m = \frac{-16}{1}[/tex]

[tex]m = -16[/tex]

Since both slopes are not the same, the relationship be modeled by a linear function

Answer:

[tex]\frac{9}{14} \ chance[/tex]

Step-by-step explanation:

1. Approach

Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, [tex]\frac{desired\ outcomes}{total\ outcomes}[/tex].

It is given that

- (63) paid with cash

- (22) paid with a debit card

- (13) paid with a credit card

First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.

2. Find the total number of customers

Add up all of the given customers, regardless of their payment type.;

[tex](cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98[/tex]

(98) total customers.

3. Find the probability

Now set up the probability, remember, the formula for finding the probability is,

[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]

The desired outcome is the number of customers who pay with cash = (63)

The total outcome is the number of customers who when to the business; (98)

Substitute in the numbers and simplify,

[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]

[tex]\frac{63}{98}[/tex]

Both of these numbers are divisible by (7), hence divide the fraction by (7)

Answer:

88 bottles

Step-by-step explanation:

Given

[tex]Cleaner =1\ gallon[/tex]

[tex]Water =10\ gallon[/tex]

Required

Determine the number of 1-pint spray bottles used

First, we get the total gallons of the cleaner and water.

[tex]Total = Cleaner + Water[/tex]

[tex]Total = 1\ gallon + 10\ gallon[/tex]

[tex]Total = 11\ gallon[/tex]

Convert to pints:

[tex]Total = 11 * 8\ pints[/tex]

[tex]Total = 88\ pints[/tex]

To get the number of spray bottles, we divide 88 pints by the size of the pint bottle.

[tex]Number = \frac{88\ pints}{1\ pint}[/tex]

[tex]Number = \frac{88}{1}[/tex]

[tex]Number = 88[/tex]

Answer: 3 weeks

Step-by-step explanation:

We have to note firstly that 12 inches = 1 foot.

The equation given to represent the height in the question, h = 3w + 3.

The number of weeks that it will take the plant to reach one foot will then be:

h = 3w + 3

12 = 3w + 3

3w = 12 - 3

3w = 9

w = 9/3

w = 3
