Answer:
Step-by-step explanation:
if Jim eats r apples and Maria eats 3times as Jim then we can represent the number of times Maria eats as 3r
Together, the both eat 96 apples that is:
r + 3r = 96 apples - this is the equation for this situation.
Solving further
r + 3r = 96apples
4r = 96 apples (divide through the equation by 4)
4/4 r = 96/4 apples
Then
r = 24 apples
Which means that Jim eats 24 apples while Maria eats 3 * 24 apples = 72 apples.
Answer:
or 6 gallons of gas.
Step-by-step explanation:
First, you have to convert both of your mixed numbers into a improper fractions.
2 = 9/4
4 = 26/6
Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.
Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM. Multiply both the nominator and the denominator by that number.
<em>4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.</em>
<em />
Repeat that for the second fraction's denominator.
<em>6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12. </em>
<em />
Then add both fractions together.
If you need to, simplify.

First we have to find how much Kyle earned taking to consideration only 38h at work
So 38*14$=532$
Now, to find commission bonus we have to 1200-532=668
Finally, we can find what dollar amount of car Kyle must sell.
We know that 668 is 8% of that number. We can use proportion and cross multiplying, so:
8% ----------- 668
100% --------x
$ - its the result.

Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be
S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be
Hence, estimated standard error for the sample mean difference would be 1.
