Answer:
16
Step-by-step explanation:
ratio is 5:4:1
David: Malachy: Paul
David gets 20 (that is 4 times more than the original ration. so need to multiply everything by 4)
4*4=16
1*4=4
new ration- 20:16:4
So David gets 20
Malachy gets 16
Paul gets 4
Answer:
Answer:y=x divided by 3 times 5.
Step-by-step explanation:
if you divide x for example 6 by 3, you will get 2 then multiply it by 5, you will get 10, which is y.
It’s reflected across the origin. Or to the right across the y axis. Then down across the x axis
Answer:
9 inches
Step-by-step explanation:
Convert from feet to inches by multiplying by 12:
3*12 = 36
Multiply by the scale factor of 1/4:
36*1/4 = 9
9 inches
Answer:
Approximately 68% of the apples have diameters that are between 7.08cm and 7.78cm.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 7.43cm, standard deviation of 0.35cm.
What percentage of the apples have diameters that are between 7.08cm and 7.78cm?
7.43 - 0.35 = 7.08 cm.
7.43 + 0.35 = 7.778 cm.
Within 1 standard deviation of the mean, so approximately 68% of the apples have diameters that are between 7.08cm and 7.78cm.
