Answer:
50
Step-by-step explanation:
500/10 = 50
Kinda like Rick rolling people on brainly.. LOL
First we find the mean of the data set: M=(4+8+13+15+24+25+28)/7=16.7. Now we find the distance of each value from the mean value:
16.7-4=12.7, 16.7-8=8.7, 16.7-13=3.7, 16.7-15=1.7, 24-16.7=7.3, 25-16.7=8.3 and 28-16.7=11.3. Now we find the mean absolute deviation by finding the mean value of the distances: (12.7+8.7+3.7+1.7+7.3+8.3+11.3)/7=53.7/7=7.67. So the mean absolute value is A) 7.67.
The mistake was that in calculating only the mean value, not the mean absolute deviation.
Answer:
The input force needed is 225 Newtons
Step-by-step explanation:
From hydraulic pressure laws, we have that the pressure at the same level throughout the body of a fluid is equal.
This means that for the Hydraulic Jack, input pressure = output pressure
Recall,Pressure is a ratio of force and area
i.e pressure = Force / Area
For the hydraulic jack to work properly, the pressure at the input end must be equal to the pressure at the output end.
From this we can compute that the Input force = 225 Newtons
Answer:
Number 3
Step-by-step explanation:
It is an acute isosceles because all the angles are acute and two sides are congruent.
Answer:
The 16 oz. bag for $5.99 is the better deal.
Step-by-step explanation:
We need to find the unit rate.
So a 16 oz. bag for $5.99, and a 22 oz. bag for $6.25.
All we need to do is divided the ounces by the prices.
16 divided by 5.99 is 2.67111853, rounded it's 2.70.
And 22 divided by 6.25 is 3.52
2.70 is way less than 3.52, so it's the cheapest and the better deal.
