Answer: 7/5m
Step-by-step explanation:
The initial value of the painting = m
Increase in the painting = 2/5
The final value of the painting will be the addition of the initial value of the painting and the increase. This will be:
= m + (2/5 × m)
= m + 2/5m
= 5/5m + 2/5m
= 7/5m
Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
Answer:
2
Step-by-step explanation:
3 plus 3 is 6 then divided by 3 is 2
I believe the correct answer from the choices listed above is the last option. THe missing step of her solution would be the statement "<span>Divide both sides of the equation by 10.4." Hope this answers the question. Have a nice day.</span>
Answer: Only 21:72:87
Explanation: We know that the side lengths are not simply 7, 24, and 29, as the sum of these is only 60.
Therefore, we need to find the scale factor they were multiplied by to have side lengths with a sum of 180.
We can use 7x+24x+29x=180.
This becomes 60x=180 and the scale factor is x=3.
7*3=21, 24*3=72, and 29*3=87.
