First bring 3x to the other side, which will give you -2y= -16-3y. Then divide everything by -2, which will give you y=8+3/2x
Answer:
now he makes $20
Step-by-step explanation:
16 times .25 is 4. 4 +16 is $20 hope this helps
<h2>
Answer:</h2>
B. 12/5
<h2>
Step-by-step explanation:</h2>
In a division, we should swap the second fraction and change the equation to times. After that, we can multiply each fraction easily.
4/5 : 1/3
= 4/5 x 3/1
= 12/5
In conclusion, the simplified quotient of 4/5 : 1/3 is 12/5
Answer:
B. N(μ, 1.30).
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation .
In this problem, we have that:
An SRS of 25 recent birth records at the local hospital was selected. In the sample, the average birth weight was = 119.6 ounces. Suppose the standard deviation is known to be σ = 6.5 ounces.
Assume that in the population of all babies born in this hospital, the birth weights follow a Normal distribution, with mean μ.
This means that for the sampling distribution, the mean is the mean of the weight of all babies born, so and .
So the correct answer is
B. N(μ, 1.30).
