Answer:
A
Step-by-step explanation:
Solve the inequality by simplifying the parenthesis with the distributive property. Then use inverse operations to isolate x.
1/6 (3-2x)<1/3x
1/6*3 - 1/6*2x < 1/3x
3/6 - 2/6x < 1/3x
1/2 - 1/3x < 1/3 x
1/2 < 1/3x + 1/3x
1/2 < 2/3x
1/2 * 3/2 < x
3/4 < x or x>3/4
Answer:
The amount invested in the mutual fund that earned 5% was $1,000
The amount invested in the mutual fund that earned 3% was $1,800
Step-by-step explanation:
Let
x ----> the amount invested in the mutual fund that earned 5%
y ----> the amount invested in the mutual fund that earned 3%
we know that
----> 
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x
<em>Find the value of y</em>
therefore
The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800
Answer:
3m = -3
Step-by-step explanation:
Subtract 2m from both sides of the equation:
-6 = 6m
Divide both sides by 2:
-3 = 3m
Answer:
B. One of the populations is normally distributed.
Step-by-step explanation:
To test a claim about two population standard deviation or variance, it is imperative that the data meets certain requirements which include :
Randomness : Data must not be biased as such it must be drawn as a random sample from a larger group.
The data must be independent. That is not related to one another, the outcome of one should not rely on the outcome or value of another.
Both groups must be drawn From a population which is normally distributed.
One group being normally distributed by stribuyed while the other isn't a requirement for hypothesis testing in this scenario.
