MAX POINTS!!! Write and solve a system of equations. Be sure to label the variables. The difference of two numbers is two. Two t

Cerrena [4.2K]

Answer:

5 and 3

Step-by-step explanation:

Let the numbers be x and y.

The equations are:

x - y = 2
2x + y = 13

Add up the equations to eliminate y and solve for x:

x - y + 2x + y = 2 + 13
3x = 15
x = 15/3
x = 5

Now find the value of y:

y = x - 2
y = 5 - 2
y = 3

Given that the data distribution is approximately normal with the minimum value of 15 and the maximum value of 98 a) Estimate th

andrew11 [14]

Answer:

a) Mean, median, mode = 56.5

b) $S = 20.75$

Step-by-step explanation:

Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.

Also, the standard deviation in a normally distributed sample can be approximated by the following formula:

$S = \frac{max - min}{4}$

a) Estimate the values of Mean, Median, and Mode.

Highest value = 98

Minimum value = 15

$\mu = \frac{98 + 15}{2} = 56.5$

b) Estimate the value of the standard deviation of these data

Max = 98

Min = 15

$S = \frac{max - min}{4}$

$S = \frac{98 - 15}{4}$

$S = 20.75$
