For 1. The bike is going 24 miles in 3 hours. To figure out how many miles it went in 1 hour you divide 24/3 which is 8 miles. If the bike went 8 miles per hour then you may now multiply it by 10 to find the total mileage in 10 hours. 10x8=80

The property taxes on a house were $1000. What was the tax rate if the house was valued at $125,000

Pachacha [2.7K]

Answer:

The tax rate was 0.8%

Step-by-step explanation:

Set up an equation:

x = tax rate

1000/125000 = x/100

Cross multiply:

1000 × 100 = 125000 × x

100000 = 125000x

0.8 = x

Check your work:

1000/125000 = 0.8/100

0.008 = 0.008

Correct!

Another way to check your work:

1000 × 100 = 125000 × 0.8

100000 = 100000

Correct!

Heavy football players: Following are the weights, in pounds, for offensive and defensive linemen on a professional football tea

Vaselesa [24]

Answer:

a) Mean = 302.25, Median = 309.5

b) Mean = 276.08, Median = 272

c) Offensive linemen tends to be heavier.

Step-by-step explanation:

We are given the following in the question:

Offense: 325, 292, 316, 308, 325, 263, 302, 311, 265, 329, 267, 324

Defense: 265, 276, 255, 306, 317, 281, 268, 282, 260, 261, 256, 286

a) mean and median weight for the offensive linemen

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{3627}{12} = 302.25$

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Sorted Data: 263, 265, 267, 292, 302, 308, 311, 316, 324, 325, 325, 329

$\text{Median} = \dfrac{6^{th}+7^{th}}{2}=\dfrac{308+311}{2} = 309.5$

b) mean and median weight for the defensive linemen

$Mean =\displaystyle\frac{3313}{12} = 276.08$

Sorted Data: 255, 256, 260, 261, 265, 268, 276, 281, 282, 286, 306, 317

$\text{Median} = \dfrac{6^{th}+7^{th}}{2}=\dfrac{268+276}{2} = 272$

c) Comparison

On comparing the mean and median of offensive and defensive linemen, offensive tends to be heavier

Can someone explain step two in the picture? Why is it that the square root of eight can be simplified to 2 square root of 2? Pl

Alik [6]

√8 = √2^2 *2

√2^2 *2 = 2√2

Basically, because 8 equals (2 to the power of 2) times 2, when you find the square root, you can take the 2^2 out, since you're finding the square root of 2 squared.

Hope I kind of make sense.
