Answer:
y= -3/5x+5
Step-by-step explanation:
B. The sample is likely to represent one portion of the population.
This is impossible to say because it's random.
On Part A you have to subtract $2.39-$1.99. Then in Part B you have to multiply $4.50 by 2. And then I think you have to add $3.79 when u are done multiplying.
Answer:
a. 5.26
Step-by-step explanation:
As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.
t score=Xbar A- Xbar B/Sd of difference of means
t score=55-51/0.76
t score=4/0.76=5.26
Answer:
The expression will be simplified into 
Step-by-step explanation:
It's like addition, when you multiply exponents that are on the same bases as each other.
