Answer:

8.5

Step-by-step explanation:

When you write out the data set, it looks like this:

5, 8, 8, 8, 8, 9, 9, 9, 10, 10

The median means the exact middle of the data set. In this case, it falls between the 8 and the 9, so the middle would be 8.5, so that's the median of the set. I hope this helps :)

Answer:

The median is 8.5

Step-by-step explanation:

The median is the middle number in a data set. For example, if you had a data set:

2, 2, 3, 4, 4

You would go forwards and backwards in the set until you found the middle number, which is 3. 3 would be the median.

However, if there is no middle number (there are an even number of points in the set), you add the two remaining numbers and divide it by two.

For example, if the final two numbers were:

2, 6

You would add 2 and 6 to get 8, and divide by 2, and you get the median 4.

In this set, we have

5, 8, 8, 8, 8, 9, 9, 9, 10, 10.

The final two numbers are 8 and 9, so you add 8+9=17, divided by 2 = 8.5.

6(1 + 3R) = 2(10R - 9) -4R

Damm [24]

Answer:

R=-12

Step-by-step explanation:

6(1 + 3R) = 2(10R - 9) -4R

Distribute 6 through the parentheses

6+18R=2(10R-9)-4R

Distribute 2 through the parentheses

6+18R=20R-18-4R

Collect like terms

6+18R=16R-18

Move the variable to the left-hand side and change its sign

6+18R-16R=-18

Move the constant to the right-hand side and change its sign

18R-16R=-18-6

Collect like terms

2R=-18-6

Calculate the difference

2R=-24

Divide both sides of the equation by 2

R=-12

if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!

What equation represents an exponential function that passes through the point (2, 80)?

Marina86 [1]

Answer:

$f(x) = (4\sqrt{5})^{x}$

Step-by-step explanation:

The exponential function looks like the following: $f(x) = b^{x}$ .

If the function passes through the point (2, 80), then:

$f(x) = b^{x}$ → $80 = b^{2}$

Solving for 'b':

$b = \sqrt{80}$ → $b=4\sqrt{5}$

Then, the equation of exponential function that passes through the point (2, 80) is: $f(x) = (4\sqrt{5})^{x}$

ELEN [110]

Answer:

The position of Michael's hands relative to the surface of the water is -1.3 meters.

Step-by-step explanation:

The question is incomplete, so below is the complete question?

Michael is doing an underwater handstand. His feet are sticking up 0.5 meters above the surface of the water. Michael's hands are 1.8 meters directly below his feet. What is the position of Michael's hands relative to the surface of the water?

Now, to find the position of Michael's hands relative to the surface of the water.

Meters of Michael's hands directly below his feet = 1.8 meters.

Meters of his feet sticking above the surface of the water = 0.5 meters.

So, to get the position of Michael's hands relative to the surface of the water we subtract meters of Michael's hands directly below his feet from meters of his feet sticking above the surface of the water:

$0.5\ meters\ -\ 1.8\ meters\\\\=-1.3\ meters.$

Therefore, the position of Michael's hands relative to the surface of the water is -1.3 meters.

the melting point of mercury is -39°C. the freezing point of alcohol is 114°C. How much cooker is the melting point of mercury t

8_murik_8 [283]

This is one of those cases where you have to believe that a minus times a minus is a plus.

114 - - 39 = 153 degrees. The freezing of mercury is 153 degrees cooler than the freezing point of alcohol. I would check your descriptions. Did you mean boiling point of Alcohol?
