Answer:
17
Step-by-step explanation:
given
2f + 4f + 2 - 3 ← simplify by collecting like terms
= 6f - 1 ← substitute f = 3 into the expression
= (6 × 3) - 1 = 18 - 1 = 17
Answer:
644ft^2
Step-by-step explanation:
Area of triangle=1/2bh
Area of square=l*l
so we have;
4 triangles with a base of 14ft and height of 16ft and 1 square with l=14ft
AreaTriangle=1/2(14ft)(16ft)=112ft*4=448ft^2
AreaSquare=14ft*14ft=196ft^2
Area Total=448ft+196ft=644ft^2
Answer:
16
Step-by-step explanation:
12 quats into cups = 48 cups
4 gallons into cups = 64 cups

Answer:
(-x)(x^2 + 4x + 5)
Step-by-step explanation:
You have to factor out the -x from the rest of the expression.
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
