Answer:
3x²(y-1)
Step-by-step explanation:
Rewrite the expression as 5x²y+4x²y-6x²y-3x². Combining like terms, we get 3x²y-3x². Now, we can factor out 3x² to get 3x²(y-1)
Answer: C. 50 pounds
Step-by-step explanation: 300 x .03 =9
p x .036 =9
p= / .036 =250
300 - 250 =50 pounds of skimmed milk needs to be removed.
Answer: Police can be 95% confident that true population proportion lies in (2%, 5%).
Step-by-step explanation:
Interpretation of confidence interval of population proportion : A person can be 95% confident that true population proportion lies in it.
Given : From time to time police set up roadblocks to check cars to see if the safety inspection is up to date. At one such roadblock they issued tickets for expired inspection stickers to 22 of 628 cars they stopped.
95% confidence interval for the true proportion of all drivers with expired inspections = (2%, 5%).
Interpretation : Police can be 95% confident that true population proportion lies in (2%, 5%).
Answer:
x= 1 when y =4 , x= 5 when y = 8 , x=2 when y = 5.
Step-by-step explanation:
y=x+3
Through this rule we have to find out the values of x when values of y are given:
y=x+3
y = 4
Substitute the value in the rule:
4=x+3
Combine the constants:
4-3=x
x= 1 when y =4
y=x+3
y = 8
8= x+3
Combine the constants:
8-3= x
5=x
x= 5 when y = 8
y=x+3
y = 5
5=x+3
Combine the constants:
5-3=x
2=x
x=2 when y = 5....
