Answer:
The standard deviation of the sample mean differences is _5.23_
Step-by-step explanation:
We have a sample of a population A and a sample of a population B.
For the sample of population A, the standard deviation
is

The sample size
is:
.
For the sample of population B, the standard deviation
is

The sample size
is:
.
Then the standard deviation for the difference of means has the following form:

Answer:
C. y<3
Step-by-step explanation:
We are required to determine the solution set of the inequality

Step 1: Add 9 to both sides

Step 2: Divide both sides by 15

The solution set of the given inequality is: y<3.
The correct option is C.
We know that
1) <span>Luis bought stock at ---------------> $66.80
2) </span><span>The next day, the price increased $13.85--------> $66.80+$13.85=$80.65
3) </span><span>This new price changed by −2 3 /4 % the following day
2 3/4%----> (2*4+3)/4----> 11/4 %----> 2.75%
so
(100%-2.75%)-----> 97.25%
t</span><span>he final stock price is $80.65*0.9725-----> $78.43
the answer is
</span>$78.43<span>
</span>
For example a × b × c = c × a × b
Answer:
Therefore the Commutative Expression is,
11 × w × 3 = 11 × 3 × w
Step-by-step explanation:
Commutative property:
The Commutative property states that order does not matter.
This property allows Two or more factors to be multiplied in any order without Changing the product.
Multiplication and addition are commutative.
For example a × b = b × a
1. 2 × 5 = 5 × 2
Therefore the Commutative Expression is,
11 × w × 3 = 11 × 3 × w
