The answer of this question is 152
Answer:
y = $15.5x
Step-by-step explanation:
Given that
Tim earns $31 after 2 hours
$46.5 earns after 3 hours,
And, $62 earns after four hours
So first determine the each hour earnings i.e.
= $31 ÷ 2
= $15.5
In two hours it would be $31 and so on
So here the equation would be
y = $15.5x
Here
y = money amount
x = number of hours
Answer:
Incomplete problem - reword
Step-by-step explanation:
A = b is given to us
Multiply both sides by c to get
a = b
a*c = b*c
The rule to multiply both sides by c is the multiplicative property of equality
Then on the right side, replace c with d. This replacement is possible due to the fact that c = d. This is using the substitution property.
So we go from
a*c = b*c
to this
a*c = b*d
Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation 
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when 
. So
So the correct answer is:
20.27
