16/35
In 1/8 of a day they plant 2/35 of an Acre
So multiply 1/8 by 8 to get one day next do this to the rest of the problem 2/35 times 8 is 16/35 and that’s the answer
Answer: 69
Step-by-step explanation:
Answer: in order to qualify, the time must be at least 15.93 minutes
Step-by-step explanation:
Let x be a random variable representing the average response times of fire departments to fire calls. Since it follows a normal distribution, we will determine the z score by applying the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
From the information given,
µ = 12.8 minutes
σ = 3.7 minutes
in order to qualify for the special safety award, the probability value would be to the right of the z score corresponding to 80%
The z score corresponding to 80% on the normal distribution table is 0.845
Therefore,
0.845 = (x - 12.8)/3.7
0.845 × 3.7 = x - 12.8
3.13 = x - 12.8
x = 12.8 + 3.13 = 15.93
Answer:
x=−18
Step-by-step explanation:
Let's solve your equation step-by-step.
x
3
+4=−2
Step 1: Simplify both sides of the equation.

3
x+4=−2
Step 2: Subtract 4 from both sides.

x=−6
Step 3: Multiply both sides by 3.

x)=(3)*(−6)
x=−18
