Answer:
$29.50
Step-by-step explanation:
Not sure how your teacher wants you to round up.
$29.4975
Rounded -> $29.50
I'm assuming 2 decimal places; would be $29.50.
Answer:
And we can find this probability with this difference and using the normal standard distribution
Step-by-step explanation:
Let X the random variable that represent the amount of Jen monthly phone of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And we can use the z score formula given by:
Replacing the info we got:
And we can find this probability with this difference and using the normal standard distribution
Answer:
Step-by-step explanation:
The purple circle, not ring is pi 7 squared = 153.93804
Then subtract the smaller circles area (pi 4 squared) = 153.9... - 103.6725576 =
50.2654824
Purple ring is 50.2654824
The entire circle is 4+3+3 (10) squared times pi = 314.1592654
( 50.2654824 / 314.1592654 ) x 100 = 15.999999998 %
A = $ 861.69
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
putting time into years for simplicity,
1 quarters ÷ 4 quarters/year = 0.25 years,
then, solving our equation
A = 850(1 + (0.055 × 0.25)) = 861.6875
A = $ 861.69
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 850.00
at a rate of 5.5% per year
for 0.25 years (1 quarters) is $ 861.69.
Answer: if you times 12x2.75 I got 33 some she can spend $33.00 and not go over.
