Answers

Answer 1

Answer:

  7.07 years

Step-by-step explanation:

The standard deviation of a population is easily calculated by a spreadsheet or calculator. Care must be taken to use the formula for population standard deviation, rather than the formula that assumes the values are a sample.

__

The attached calculator shows the standard deviation is about 7.07 years.

_____

Additional comment

The population standard deviation is the square root of the variance. The variance is the mean of the squares of the values, less the square of the mean of the values. The second attachment shows the calculation done this way.

The units of standard deviation are the same as the units of the members of the population. Here, that is "years."

The functions f and g are defined by f: x = 4 - x and g: x = hx² + k. If the composite function gf is given by gf: x + 2x² - 16x + 26, find
(a) the value of h and of k,​

Answers

Answer:

Step-by-step explanation:

f(x) = 4-x

g(x) = h[tex]x^{2}[/tex]+k

g(f(x)) = 2[tex]x^{2}[/tex]-16x+26

so put  f(x)  in g(x)

h[tex](4-x)^{2}[/tex]+k

h((4-x)(4-x) + k

h([tex]x^{2}[/tex]-8x+16)+k

if h = 2 , then

2[tex]x^{2}[/tex]-16x+32 + k

and we want 26  instead of 32 so subtract 6 so K = (-6)

2[tex]x^{2}[/tex]-16x+32 + (-6)

2[tex]x^{2}[/tex]-16x+32 - 6

2[tex]x^{2}[/tex]-16x+26

h=2

Combine these radicals - square root 5 - 3 square root 5

Answers

Answer:

Step-by-step explanation:

if you combine the radicals, you will receive the answer that is shown above.

Answer:

[tex]-4\sqrt{5}[/tex]

Step-by-step explanation:

Given expression: (square root 5) - (3 square root 5)

⇒ [tex]-\sqrt{5} - 3\sqrt{5}[/tex]

Since we have √5 common in both terms, let's factor √5.

⇒ [tex]\sqrt{5} - 3\sqrt{5}[/tex]⇒ [tex]\sqrt{5} \times (-1 - 3)[/tex]

Finally, we can simplify;

⇒ [tex]\sqrt{5} \times (-4)[/tex]⇒ [tex]-4\sqrt{5}[/tex]

Therefore, the combined radical of (square root 5) - (3 square root 5) is [tex]-4\sqrt{5}[/tex]

Gavin is selling water bottles at a baseball game to help raise money for new uniforms. before the game, he buys 75 water bottles for a total of $25. at the game, he sells all of the bottles for $1.20 each. how much profit does gavin make?

Answers

The amount of profit Gavin made in selling the water bottles at the base ball game is $65.

How to find profit?

He bought 75 bottle water for a total of $25.

He sales all of the  bottles for $1.20 each.

Therefore,

profit = selling price - cost price

Hence,

cost price = $25

selling price = 1.20(75) = $90

Finally,

profit = 90 - 25 = $65

Find the measures of angles Q and S. Number 7!

Answers

Step-by-step explanation:

by the way, you are completely and exactly right at 6.

Q is the inscribed angle of the (inner) arc angle TR.

and as such it is half of that arc angle TR.

S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :

S is half of the outside arc angle between T and R.

as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then

360/2 = 180°

so, yes,

x + 2 + 9x - 7 = 180

10x - 5 = 180

10x = 185

x = 18.5

Q = x + 2 = 18.5 + 2 = 20.5°

S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°

Mara ran 3 km north and then 4 km east. she will finish her run by running directly home. what was the total distance of her run? a right triangle with side lengths 8 kilometers and 4 kilometers. a point at intersection of the side with length 3 kilometers and the hypotenuse is labeled mara's house. 5 km 7 km 12 km 14 km

Answers

Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

How to determine the total distance of Mara's run.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

c is the hypotenuse.a is the adjacent side.b is the opposite side.

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Now, we can determine the total distance of Mara's run:

Total distance = 3 + 4 + 5

Total distance = 12 km.

The expression of Volume in cubic meter  [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

The correct option is (1)

What is Volume?

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

 

Volume of rectangular pyramid= [tex]\frac{1}{3}[/tex] * base area* height

                                                   = [tex]\frac{1}{3}[/tex] * 6*8*(10-4)

                                                   =[tex]\frac{1}{3}[/tex] * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =[tex]\frac{1}{3}[/tex] * 6*8*6 + 4*6*8

                     = [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

The value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle shown in the picture.

The angle APE = 90 degree (from the figure)

25x + 15 = 90

25x = 75

x = 3

The measure of arc CDE = (20x + 4) + (33x - 9) = 53x -5

= 53(3) -5

= 154 degree

Thus, the value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.
