This is 1 whole because you have to make the equation 1/4+9/12 and then you have to find the Lowest Common Denominator (LCD) then it will look like 3/12+9/12= 12/12=1 whole Hope that helped

ziggy sells coffee and donuts , the total number of cofees and donuts ziggy sells today is 100. Ziggy charges 3$ for coffee and
sergejj [24]
You use a system of equations
x= coffee
y= donuts
x+y=100
3x+y=180
there’s 3 ways to solve system of equations substitution graphing and elimination. it would be easiest to use substitution here. So you multiply x+y=100 by -1 so it become -x-y=-100. then you combine it with the other equation and get 2x=80 so x=40 which means 40 cups of coffee were sold then you plug it back in to find y. 40+y=100. y=60.
y= 60 (donuts). x= 40 (coffee)

For a sample of n = 30 scores, X = 45 corresponds to z = 1.50 and X = 40 corresponds to z = +1.00. What are the values for the s
Ber [7]

Answer:

Sample mean = 30

Standard deviation = 10

Step-by-step explanation:

A system with two linear equations can be modeled with the information given in order to find the sample mean (M) and the standard deviation (s):

z=\frac{X-M}{s}\\\\1.50=\frac{45-M}{s} \\1.00=\frac{40-M}{s}

Solving the linear system:

40-M = \frac{45-M}{1.5}\\M=\frac{15}{0.5}\\M=30\\\\s=\frac{45-30}{1.5}\\s=10

The sample mean is 30 while the standard deviation is 10.
