Nadia is right because the amount of each slice could be different by a thin slice and can effect other slices too therefore Nadia is right

Nadia

6/8 is 3/4 and both is 75% of a pizza but, the eighths of a pizza is a smaller slice of pizza.

4/4 is four slices of pizza
8/8 is eight slices of pizza         They are different amounts.

Answer:

c) 44000 miles

Step-by-step explanation:

The regression line has the following format:

y = bx + a

In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.

In this problem, we have that:

a = 24000, b = 10. So

y = 10x + 24000

A person who spent $ 2000 is predicted to have flown:

This is y when x = 2000.

y = 10(2000) + 24000

y = 44000

So the correct answer is:

c) 44000 miles

Members of a junior high basketball team want to brag about how tall they are. First, they measured each player’s height in inch
enyata [817]

First to find the median we need to put the numbers in order from least to greatest.

62, 64, 65, 66, 67, 69, 83

Now take a number from each side

64, 65, 66, 67, 69

Once again.

65, 66, 67

On last time

66

So the median is 66.

Now to find the mean we must add all the numbers up

64+67+83+65+66+62+69

which equals 476

Now divide 476 by the total number of heights which is 7

476/7=68

So the mean is 68

Answers: Mean; 68 Median; 66

Radda [10]

Answer:

  • 4099 yes
  • 4110 no
  • 5909 no
  • 5011 yes

Step-by-step explanation:

The digits will be related by a factor of 10 if they are the same digit. 4099 and 5011 have the same digit in the tens and ones places. 4110 and 5909 do not.

The velocity v of blood that flows in a blood vessel with radius r and length ℓ at a distance r from the central axis is v(r) =
pogonyaev
v(r)=4P\eta\ell(R^2-r^2)

(assuming R is the radius of the vessel, and that 0\le r\le R)

The average velocity of the blood is given by

\displaystyle\frac1{R-0}\int_{r=0}^{r=R}v(r)\,\mathrm dr
=\displaystyle\frac{4P\eta\ell}R\int_{r=0}^{r=R}(R^2-r^2)\,\mathrm dr
=\dfrac{4P\eta\ell}R\left(\dfrac23R^3\right)
