Answer:
350N, 800 N
Step-by-step explanation:
for question no 6
mass (m) = 70 kg
acceleration (a) = 5 m/s²
Force (F) = m * a = 70 * 5 = 350 N
for question no 7
mass (m) = 80 kg
acceleration (a) = 10 m/s²
Force (F) = m * a = 80 * 10 = 800 N
Hope it will help :)❤

Answer:
The 80% confidence interval for the mean per capita income in thousands of dollars is between $20.8 and $21.4.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 21.1 - 0.3 = $20.8.
The upper end of the interval is the sample mean added to M. So it is 21.1 + 0.3 = $21.4.
The 80% confidence interval for the mean per capita income in thousands of dollars is between $20.8 and $21.4.
Probability of getting heads on first try is 1/2
probability of getting heads on 2nd try is 1/2
probability of getting both is : 1/2 * 1/2 = 1/4
These are both independent because 1 does not effect the other
