Answer:
Step-by-step explanation:
-3(-4x-3) = 20
Opening bracket
12x + 9 = 20
12x = 20 - 9
12x = 11
x = 11/12
Answer:
a) Expected value of the mean = 0.793 percent
b) Standard error = 0.019 percent.
Step-by-step explanation:
Given
mean = μ = 0.793 percent
Standard deviation = σ = 0.114 percent
a) The sample mean is related to the population mean through
μₓ = μ = 0.793 percent
Hence, the expected value of the sample mean = 0.793 percent.
b) The standard error is given as
Standard error = σ/√n
where n = sample size = 36
Standard error = (0.114/√36)
Standard Error = 0.019 percent.

Answer:
he needs 55 to cover the one rectangular side of the tent with the rip
one rectangular side=55
If Marcus’s dad wanted to re-cover the whole tent including the bottom, he would need 189.
3 rectangular sides=165

The linear function is given by:
<h2>
Step-by-step explanation:</h2>
It is given that the rate of change of the linear function is equal to the average rate of change of function f on the interval [-1, 1].
The slope(m) or average rate of change of the linear function will be:
and the linear function pass through (1,-2)
We know that the equation of a line with given slope m and passing through point (a,b) is given by:
Here (a,b)=(1,-2)
and 
Hence, the equation of linear function is:
Answer:
1400 individual balloons
Step-by-step explanation:
Total bags of balloons needed = 8 bags
Each balloon bag contains 175 balloons.
Thus,
175 balloons × 8 = 1400 balloons.
Hence, the parent teacher association need to buy 1400 individual balloons.
