Answer:
Danielle earns $1.20 more than Mackenzie (per hour)
Step-by-step explanation:
To find out how much money per hour each person earns, you would divide the earinings by the number of hours;
Danielle: $36.80/4 = $9.20 per hour
MackKenzie: $50.40/6 = $8.40 per hour
To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;
9.40 - 8.20 = $1.20
Thus, Danielle earns $1.20 more than Mackenzie per hour.
Answer:
Mr mehra's salary is 26250
Step-by-step explanation:
suppose,
Mr mehra's salary is x
so,
He spends in food = 30% of x
=(30/100) . x [x%=x/100]
= 30x/100
=3x/10
He spends in charity =10% of x
=10x/100
=x/10
Money left = 15750
so,
x = 3x/10 + x/10 + 15750
⇒x - 3x/10 - x/10 = 15750
⇒(10x-3x-x) /10 = 15750
⇒6x/10 = 15750
⇒6x=157500
⇒x = 157500/6
⇒x = 26250
∴Mr mehra's salary is 26250
I think the answer would be C
As it is basically a straight line so there wouldn't be necessary for there to be a scatter diagram for it.
I may be wrong so take it with a grain of salt
Answer: 95% certain that true proportion of population "p" is contained in (0.604, 0.781)
Step-by-step explanation:
We know that a 95% confidence interval is a range of values that you can be 95% sure that true mean of the population or true proportion of population lies in it .
Given : The 95% confidence interval for p was calculated to be (0.604, 0.781).
It means that we are 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Hence, the correct interpretation for this interval :- 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
