Find the mean for the set of data.
0.2, 0.21, 0.17, 3.22, 0.2

Answers

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Answer:

0.8

Step-by-step explanation:

The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =

(4)/5 = 0.8

0.8 is the mean for the given set.

if f(x)=2^x and g(x)=x-4. The graph of (fog)(x) is shown below. What is the range of (fog)(x)?

Answers

Answer:

C) [tex]y > 0[/tex]

Step-by-step explanation:

[tex]f(x)=2^x\\\\g(x)=x-4\\\\(f\circ g)(x)=f(g(x))=f(x-4)=2^{x-4}[/tex]

This means that the parent function, [tex]f(x)=2^x[/tex], will shift 4 units to the right along the x-axis, so this DOES NOT affect the range (nor the domain either). Thus,  [tex]y > 0[/tex] would be the range.

The standard form is ( -8m⁵+10m⁴+9m³-16m²+15m ).

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be solved as:-

E = ( 3m² - m )( 4m³ + m - 5 )

E = -8m⁵ - 2m⁴ + 10m³ - 15 m² - 4m³ - m² + 5m

E =  ( -8m⁵+10m⁴+9m³-16m²+15m ).

Therefore, the standard form will be ( -8m⁵+10m⁴+9m³-16m²+15m ).

With a coupon you can get a pair os shoes that normally costs $84 for only $72 what percentage was the discount

Answers

Given parameters:

Original selling price = $84

Discounted Selling price  = $72

Unknown:

Percentage discount = ?

Solution:

To find the percentage discount;

  Find the discount amount   Then find the percentage discount from this value when you place it over the original selling price

Discount = Original selling price  - Discounted selling price

               = $84 - $72

               = $12

Now,

  Percentage discount  = [tex]\frac{12}{84} x 100[/tex]   = 14.3%

The percentage discount is 14.3%

Find the area

Answers

Answer:

  240 square feet

Step-by-step explanation:

The area of a composite figure can be found by adding the areas of its parts.

__

Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.

The sum of the areas of these parts is ...

  rectangle area + triangle area

  = (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²

  = 240 ft² . . . . area of the figure

_____

Additional comment

You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

if h(x) = x^2-5x+7 find each value

1/3*h(-8)

Answers

if h(x) = [tex]x^{2} -5x+7[/tex] so the value of  [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.

Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.

we have h(x) = [tex]x^{2} -5x+7[/tex]

So, substitute the value [tex]x=-8[/tex] in the equation,

h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]

        = [tex]64+40+7[/tex]

        = [tex]111[/tex]

And now we shall multiply it with [tex]\frac{1}{3}[/tex],

we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Selling Price $40.00 Rate of Sales Tax 3% Sales Tax ?

Answers

Answer:

tax: $1.20total cost: $41.20

Step-by-step explanation:

The sales tax is found by multiplying the tax rate by the item price. The total cost will be the sum of the item price and the tax.

__

  tax = 0.03 × $40 = $1.20

  total cost = selling price + tax = $40 +1.20 = $41.20

On Monday, Jolene played basketball and made 75% of the shots she took. If she missed 7 shots, how many shots did she take? Show your work.​

Answers

Answer:

She took 28 shots, 7 shots would be the remaining 25% so you multiply it by 4 to get 100% or 7 × 4 = 28

missed shots = 7 = 25%             since 75% are successful

proportionality table

25% ...............7

100% ........... = 7 x 100% : 25% = 28

total = 28 shots

Then you simplify and get n^2=36

Finally you find the square root of both side, and you get n=6

A package of 5 pairs of insulated gloves costs ​$43.95. What is the unit price of the pairs of gloves​?

Answers

Answer:

5.89 dollars

Step-by-step explanation:

To find the unit price, we use t/q where t is the total price and q is the quantity.

Therefore, it costs 5.89 dollars for a pair of gloves.

The unit price of the pair of gloves will be $8.79 for each pair of gloves.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

A package of 5 pairs of insulated gloves costs ​$43.95. Then the unit price of the pairs of gloves is calculated as,

Rate = $43.95 / 5

Rate = $8.79 for each pair of gloves

The unit price of the pair of gloves will be $8.79 for each pair of gloves.
