Answer:

4

Step-by-step explanation:

Given the data:

X : 20,25,30,20,30

Mean absolute deviation :

Σ(x - xbar) / n

n = sample size = 5

xbar = ΣX / n = (20+25+30+20+30) /5

xbar = 25

((20-25) + (25-25) + (30-25) + (20-25) + (30-25)) / 5

We take the absolute values, hence, negative signs are ignored :

(5 + 0 + 5 + 5 + 5) / 5

20 / 5

= 4

Answer:

$43.91

Step-by-step explanation:

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

$35.60 + $2.58 (tax) = $38.18

$38.18+ $5.73 (tip at 15%) = $43.91 total

Answer:

250 cm squared

Step-by-step explanation:

The formula for an area of a kite is:

A=pq/2

--------

p = 20 and q = 25

Multiply the two together (20 × 25)

Then divide by 2 (500 ÷ 2)

Then you get your answer (250)

Whenever you find the area, be sure to add the ² symbol or squared, or else it will be wrong.

Answer:

1263.7032 feets

Step-by-step explanation:

Distance from Ferguson corporation to Springdale Town center ; let the distance = x

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 27 = x / 2000

0.5095254 * 2000 = x

1019.0508 feets

Distance from Springdale to Subway station, this is the hypotenuse :

Hypotenuse = √(1019.0508² + 2000²)

Hypotenuse = √5038464.7

Hypotenuse = 2244.6524 feets

Total distance walked from Ferguson to Springdale, then to Subway ;

(1019.0508 + 2244.6524) feets = 3263.7032 feets

Additional distance walked :

(3263.7032 feets - 2000 feets) = 1263.7032

In this exercise we have to calculate the distance knowing about the laws of a triangle, so we have to:

[tex]H=1263.7032 feets[/tex]

We can use the definition of tangent to calculate:

[tex]Tan\theta = opposite / Adjacent\\Tan 27 = X / 2000\\0.5095254 * 2000 = X\\=1019.0508 feets[/tex]

Now using the Pythagorean theorem we have:

[tex]H = \sqrt{(1019.0508^2 + 2000^2)}\\H = \sqrt{5038464.7}\\H = 2244.6524 feets\\(1019.0508 + 2244.6524) = 3263.7032 feets\\(3263.7032 feets - 2000 feets) = 1263.7032[/tex]

Answer:

Step-by-step explanation:

x^2-18x+58=0

[tex]x^{2}[/tex] - 18x  + [tex](-9)^{2}[/tex]  +58 = [tex](-9)^{2}[/tex]

[tex](x-9)^{2}[/tex] +58 = 81

[tex](x-9)^{2}[/tex]  = 23

x - 9 = [tex]\sqrt{23}[/tex]

x = [tex]\sqrt{23}[/tex] + 9

Answer:

Your car's value decreases around 20% to 30% by the end of the first year. From years two to six, depreciation ranges from 15% to 18% per year, according to recent data from Black Book, which tracks used-car pricing. As a rule of thumb, in five years, cars lose 60% or more of their initial value.

Answer:the answer is c

Step-by-step explanation:

There is not enough information to make a conclusion about the population mean. Then the correct option is B.

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

A class is gathering data on the amount of time spent watching videos each day.

Each student collected 10 pieces of data and will compile that data to determine a population mean.

One student, Megan, has a sample mean of 45.67.

The population mean can be approximated by the mean of an unlimited number of sampling means within the group according to the central limit theorem.

It is not possible to determine the population from Megan's sample mean because it only represents a small portion of the whole population.

There is not enough information to make a conclusion about the population mean.

Then the correct option is B.

Answer:

A. 69.12 in.³

Step-by-step explanation:

Volume of the crayon balloon = volume of the cone + volume of the cylinder

= ⅓πr²h + πr²h

✔️Volume of Cone = ⅓πr²h

r = ½(2) = 1 in.

h = 3 in.

Volume of cone = ⅓*π*1²*3 = 3.142 in.³

✔️Volume of Cylinder = πr²h

r = ½(2) = 1 in.

h = 21 in.

Volume of Cylinder = π*1²*21 = 65.97 in.³

✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115

= 69.12 in.³ (nearest hundredth)

Answer: 8,4, and 12

Step-by-step explanation:

Given

Jack bought 24 apples and divided them in the ratio of 2:1:3.

Suppose they get the number of apples as [tex]2x,x,3x[/tex] such that their ratio remains the same

[tex]\therefore 2x+x+3x=24\\\Rightarrow 6x=24\\\Rightarrow x=4[/tex]

So, each person gets

[tex]2x=2\times 4=8\\x=4\\3x=3\times 4=12[/tex]

Answer:

Jack's brother received 8 apples, his friend received 4 and Jack received 12 apples.

Answer: 0.14

Step-by-step explanation

The required conditional probability would be 0.71.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The conditional probability is defined as:

P(A|B) = P(A∩B)/P(B)

From the given two-way table, we get

Drive to school and senior = 25

Senior = 25+5+5

= 35

Total = 2+25+3+13+20+2+25+5+5

= 100

Now,

P( Drive to School and Senior) = 25 / 100

P( Senior) = 35/ 100

Thus,

P( Drive to School | Senior) = 25 / 35 = 0.71

Therefore, the required conditional probability would be 0.71.
