Answer:

Step-by-step explanation:

The stem and leaf plot represent the list of numbers:

15, 18, 46, 50, 50, 50, 50, 57

The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values.

The formula for the mean of a population is

$\mu = \frac{{\sum}x}{N}$

The formula for the mean of a sample is

$\bar{x} = \frac{{\sum}x}{n}$

Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:

$\frac{336}{8} = 42$

I really need help with 15 and 16 please

Mandarinka [93]

Answer:

15. 50 kg

16a. 5 kg

16b. 3.75 kg

Step-by-step explanation:

The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².

F = ma

m = F/a . . . . . divide by a

15. m = (250 N)/(5 m/s²) = 50 kg

16a. m = (15 N)/(3 m/s²) = 5 kg

16b. m = (15 N)/(4 m/s²) = 3.75 kg

Comment on units

Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).

Answer:

All the GCFs look good! Here's the simplified fractions:

Step-by-step explanation:

1. 2/3

2. 3/4

3. 3/7

4. 3/16

5. 27/29

6. 4/11

7. 2/11

Simply divide the numerator by the GCF to find the simplified numerator, and the denominator by that same GCF to find the simplified denominator!

A line passes through the point (-4,3) and has a slope of -5/2

Jlenok [28]

Answer:

y=(-5/2) x -7

Step-by-step explanation:

y=mx+b

m=(-5/2)

To find b:

3=(-5/2)times"x" + b

3=(-5/2)times(-4) + b

3= 10 +b; b=-7

y=(-5/2) x -7
