Answer:

The mode if 5, because 5 Acres 8 times, which is more than any other occurs more than once. The median 6, and this is because when you line up the numbers in Order in Cross I'm off to fly in the middle number, it is 6. I rounded it to the mean in about 6.4. I got this by adding all the numbers up, we're doing 12 + 40 + 18 +, Eta, and got the total of 165. Cuz there is a total of 26 data points, I divided those numbers and God 6.3461, which ends up rounding to 6.4

Which would you use to compare 10 / 12 and 2 / 5 a common numerator or common denominator?

BartSMP [9]

We can compare 2 fractions by means of the cross multiplication method. In our case, we have

since 50 is greater than 24 then 10/12 is greater than 2/5:

$\frac{10}{12}>\frac{2}{5}$

Jane is painting her room. She mixes 3 pints of blue paint with 4 pints of red paint to get her desired color. Which equation ca

Lady bird [3.3K]

Well if she added three blue and four red originally, and is now using 16 red then we would divide 16 by the original four. Which means to get the number of blue we are gonna end up multiplying by four. So three times four is twelve. Which means she would use 12 blue and 16 red to get the same color she got with 3 blue and 4 red earlier. The equation, lets use x for blue and y for red, would be 4(3x + 4y) = desired color

What number is to 100 as 4 is to 78

vitfil [10]

Hello,

4 is to 78 as x is to 100, we write it as a ratio:

$\frac{4}{78}= \frac{x}{100} \\ \\ x= \frac{100*4}{78} \\ \\ \boxed{x= \frac{200}{39}=5.13}$

A skateboarder starting from rest accelerates down a ramp at 2 m/s for 2 s. What is the final speed of the skateboarder

Sedaia [141]

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)

Acceleration of the skateboard (a) = 2 m/s²

Time taken by the skateboard (t) = 2s

By using equation of motion, we get:

$\bf \longrightarrow v = u + at \\ \\ \rm \longrightarrow v = 0 + 2 \times 2 \\ \\ \rm \longrightarrow v = 4 \: m {s}^{ - 1}$

$\therefore$ Final speed of the skateboard(v) = 4 m/s
