Calculate the amount 1 man can eat per day from the known amounts:
200 kg / 40 days = 5 kg of wheat per day / 20 men = 0.25 kg per man per day.
Now calculate the time it will take 10 men:
10 men x 0.25 kg per day = 2.5 kg per day.
300 kg / 2.5 kg per day = 120 days
Answer:
t+f=12
7t+3f=72
Step-by-step explanation:
7pts for t + 3pts for f =72 pts
7t+3f+72
Option B
The amount in account after 3 years is $ 12444.66
<em><u>Solution:</u></em>
Given that,
$9500 is invested at an interest rate of 9%, compounded continuously
<em><u>The formula for total amount when interest is compounded continuously:</u></em>
Where "p" is the principal
"r" is the rate of interest
"t" is the number of years
In this problem,
p = 9500
t = 3 years
<em><u>Substituting the values we get,</u></em>
Thus amount in account after 3 years is $ 12444.66
Answer:
a) Scores of 2 and higher are significantly high
b) Scores of -2 and lower are significantly low
c) Scores between -2 and 2 are not significant.
Step-by-step explanation:
Mean = 0
Standard deviation = 1
a. significantly high (or at least 2 standard deviations above the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
So scores of 2 and higher are significantly high
b. significantly low (or at least 2 standard deviations below the mean).
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores of -2 and lower are significantly low
c. not significant (or less than 2 standard deviations away from the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores between -2 and 2 are not significant.
Answer:
A) f(x) = x^2 +8(x+2)
Step-by-step explanation:
We will start by putting y=0
0 = x^2+8(x+2) -Apply distributive property
0 = x^2+8x+16
0=(x+4)(x+4)
0=x+4, 0=x+4
x=-4
There is only one zero, and that is x=-4
Brainiest would be appreciated.
