Answer:

15.8

Step-by-step explanation:

Rounding to the nearest tenths means we are focusing on the number 7 and the number after it- 5. Because it is a 5, we will round the number 7, one higher. If it were to be a 4, it would stay a 7.

Answer:

15.8 is the Answer

Step-by-step explanation:

1) 5 in the hundreds place will be turn to 6 due to the fact that in can round up because a 5 is in the thousandth place.

2) Since 6 is 5 and greater than 5 it will round up 7 in the tenths place to 8.

22.26 x 10^7 is the correct answer

Multiply the decimal numbers:

5.3 x 4.2 = 22.26

When multiplying scientific numbers, add the exponents together: 4+3 = 7

So you now have 22.26 x 10^7

Now you need to convert 22.26 to a scientific number, by only having one number to the left of the decimal point.

You need to move the decimal 1 place to the left, which means you need to add 1 more to the exponent.

The final answer would be 2.226 x 10^8

Answer:

K'= (-2, 4)

Step-by-step explanation:

First we are going to rotate our point 270° counterclockwise.

The rule for a 270° counterclockwise rotation is [tex](x,y)-->(y,-x)[/tex], which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:

[tex](x,y)-->(y,-x)[/tex]

[tex](-7,-2)-->(-2,-7)[/tex]

[tex](-7,-2)-->(-2,-(-7))[/tex]

[tex](-7,-2)-->(-2,7)[/tex]

Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:

[tex](x,y)-->(x,y-3)[/tex]

[tex](-2,7)-->(-2,7-3)[/tex]

[tex](-2,7)-->(-2,4)[/tex]

We can conclude that the coordinates of K' are (-2, 4)

In a distribution, if the data is skewed left, the mean is less than the median; if skewed right, the mode is often less than the median, which is less than the mean.

In a distribution, if the data is skewed to the left, the mean is less than the median, which is often less than the mode. On the other hand, if the data is skewed to the right, the mode is often less than the median, which is less than the mean. Therefore, the most likely statement to be true for this distribution is B. The mean is less than the median.

The statement that  is most likely to be true for this distribution is The mean is greater than the median.

This distribution is "bunched up" at the left and has a larger tail to the right, indicating that it is right skewed. The median will be nearer the left side of the graph in a right-skewed distribution since most of the data points are at the smaller end.

The mean will rise and become greater than the median due to the increased numbers in the "tail". A positively skewed distribution, also known as a right-skewed distribution in statistics, is one in which the majority of values are concentrated at the left tail of the distribution while the right tail is longer. The distribution that is negatively skewed is directly opposed by the positively skewed distribution.

Answer:

See below...

Step-by-step explanation:

Theoretical probability is the probability that something should happen based on the beginning conditions.  Such as having a jar of 30 marbles with 5 being blue.  The probability of pulling out a blue marble when selecting 1 marble is

5/30, or 1/6.  Theoretically you should pull one blue marble out every 6 times you pull a marble out.  

This isn't guaranteed to happen though, that's where experimental probability comes form.

Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes.  This is based on what actually happened.  Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles.  Your experimental probability is

2/10, or 1/5, which doesn't match the theoretical probability.  The more times this experiment is conducted, the closer your result will be to the theoretical probability

===================================================

Explanation:

The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.

The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135

Therefore, 15*b = 135

Divide both sides by 15 and we isolate b

15b = 135

15b/15 = 135/15

b = 9

So the base is 9

Check:

area = base*height = 9*15 = 135

so the answer is confirmed

side note: we never use the value 17 at all. It is likely put in there as a distraction.

The answer is 2. The rate of change between -1 and 0 is 3 and between 0 and -1 is 1. The average between 3 and 1 is 2.

Answer:

- 2

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 1, 1 ]

f(b) = f(1) = 1 - 2 = - 1

f(a) = f(- 1) = 1 + 2 = 3

Hence

average rate of change = [tex]\frac{-1-3}{1-(-1)}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

The given function is

[tex]f(x) = 2 {x}^{3} + 21[/tex]

Let

[tex]y= 2 {x}^{3} + 21[/tex]

Solve for x.

[tex]2 {x}^{3} = y - 21[/tex]

[tex] {x}^{3} = \frac{1}{2} y - \frac{21}{2} [/tex]

Take cubic root of both sides,

[tex]x = \sqrt[3]{ \frac{1}{2} y - \frac{21}{2} } [/tex]

x is defined for all real values of y.

The range refers to the values of y, for which x is defined.

Hence the range is all real numbers.

Since the scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute, the equation that can be used to represent the divers altitude is [tex]y = -5x + 1.3[/tex]

The standard equation is [tex]y = mx + b[/tex]

y,x = variables

m = rate of change

b = initial value of y.

y = the height of the scuba driver after x minutes.

Given that b = 1.3

m = -5.6(decrease in altitude)

Then the equation can be written as ; [tex]y = -5x + 1.3[/tex]

hence scuba driver height is given by the equation [tex]y = -5x + 1.3[/tex]

The equation that represents the scuba diver's altitude after jumping into the water is y = 1.3 - 5.6t, where y is in meters and t is in minutes.

Let y represent the diver's altitude in meters relative to sea level after t minutes. Initially, at sea level, we have y(0) = 1.3. Due to the descent in water, the altitude decreases by 5.6 meters per minute, which means the altitude change per minute can be represented by
-5.6t. Thus, the equation that can be used to represent the diver's altitude as a function of time is:

y = 1.3 - 5.6t

where y is in meters and t is in minutes.

The average distance from the sun to Mars can be found by setting up an equation based on the given information. Subtracting 550 from the average distance to Jupiter gives the average distance to Mars, which is 228 million km.

We know that the average distance from the sun to Jupiter is 778 million km, which is 550 million km more than the distance from the sun to Mars. We could express it in the form of an equation and solve to find the average distance that Mars is from the sun. Let's denote that Mars is 'x' million km from the sun. Then we can write it as:

x + 550 = 778

To find x, we need to subtract 550 from both sides of the equation, which gives us:

x = 778 - 550

And so, the distance from the sun to Mars is x = 228 million km.

Answer:

11.  ×8; ×27; ÷8

12. ÷16; ÷256; ×16

13. ×8

14. ×4

Step-by-step explanation:

11. g(x) =5x³

g₁ = 5x₁³

g₂ = 5x₂³

g₂/g₁ = (x₂/x₁)³

a. x is doubled. g₂/g₁ = (2x₁/x₁)³ = 2³ = 8

If x is doubled, g is multiplied by eight.

b. If x is tripled, g₂/g₁ = (3x₁/x₁)³ = 3³ = 27

If x is tripled, g is multiplied by 27.

c. If x is halved, g₂/g₁ = (½x₁/x₁)³ = (½)³ = ⅛

If x is halved, g is divided by 8.

12. ƒ(x) = 3/x⁴

f₁ = 1/x₁⁴

f₂ = 1/x₂⁴

f₂/f₁ = (x₁/x₂)⁴

a. x is doubled. f₂/f₁ = (x₁/2x₁)⁴ = (½)⁴ = 1/16

If x is doubled, f is divided by 16.

b. If x is quadrupled, f₂/f₁ = (x₁/4x₁)⁴= (¼)⁴ = 1/256

If x is tripled, f is divided by 256.

c. If x is halved, f₂/f₁ = [x₁/(½x₁)]⁴ = 2⁴ = 16

If x is halved, f is multiplied by 16.

13. V = ⁴/₃πr³

V₁ = ⁴/₃πr₁³

V₂ = ⁴/₃πr₂³

V₂/V₁ = (r₂/r₁)³

r is doubled. V₂/V₁ = (2r₁/r₁)³ = 2³ = 8

The volume of the sphere is multiplied by 8.

14. V = πr²h

V₁ = πr₁²h

V₂ = πr₂²h

If r is doubled and h stays the same, V₂/V₁ = (2r₁/r₁)² = 2² = 4

The volume of the cylinder is quadrupled.

For this case we have that the law of cosine is given by:

[tex]c ^ 2 = a ^ 2 + b ^ 2-2 (a) (b) * cos (x)[/tex]

Where:

[tex]c = 12 \ ft\\a = 8 \ ft\\b = 9 \ ft[/tex]

We replace:

[tex]12 ^ 2 = 8 ^ 2 + 9 ^ 2-2 (8) (9) * cos (x)\\144 = 64 + 81-144 * cos (x)\\144 = 145-144 * cos (x)\\-1 = -144cos (x)\\cos (x) = \frac {1} {144}\\x = cos ^ {- 1} (\frac {1} {144})\\x = 89.60 \ degrees[/tex]
