Answer:
Numerator = 18
Denominator =75
Step-by-step explanation:
Given the expression
9/15=x/30=45/x
We can equate any two fractions
9/15= x/30
Criss multiply
15x = 9×30
15x = 270
x = 270/15
x= 18
Numerators is 18
Similarly
9/15 = 45/x
1/15 = 5/x
x = 5×15
x = 75
The denominator is 75

Step-by-step explanation:
I think the answer is 300 or over 300. Maybe even 750, I'm not really sure
Answer:
a) 0.216
b) 0.1587
c) 0.369
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12.2 grams
Standard Deviation, σ = 2.8 grams
We are given that the distribution of weights of impurities per bag is a bell shaped distribution that is a normal distribution.
Formula:
a) P(contains less than 10 grams of impurities)
P(x < 10)
Calculation the value from standard normal z table, we have,

b) P(contains more than 15 grams of impurities)
P(x > 15)
Calculation the value from standard normal z table, we have,

c) P(contains between 12 and 15 grams of impurities)

d) The mean divide the data in exactly two parts. Since 15 is farther away from the mean as compared to 10, the probability obtained in part (b) is smaller as compared to probability obtained in part (a).
To determine what the line looks like, simply change it to y = mx + b form. Then simply either make a table of values. And substitute any points into the equation and obtain points to plot on the graph. Or you can simply plot the graph by using the slope of the equation.
Y = 8 - 6x/2
Y = 4 - 3x
Y = -3x + 4.
This would be the rearranged equation.
