Vsphere=(4/3)pi times r^3
r=radius
given that r=2
v=(4/3)pi2^3
v=(4/3)pi8
v=32/3pi cubic inches
about 10.66666pi cubic inches or hmm, roughly 31 cubic inches (guestimated in head)
<span><span>anonymous </span> 3 years ago</span>we are solving for A,
A is the future amount A=?
P is the present value, so we were told 7,900, so p=7900
r is the interest rate, so 4.3%, but in decimal form so r=0.043
k is the how often it is 'compounded', it says quarterly, so k=4
n is how long, 3 years, so n=3
<span>A=P(1+<span>rk</span><span>)<span>n∗k</span></span></span>
plug in the values
<span>A=8981.51</span>
Answer:
Total no.of possible outcomes = 200 × 4 = 800
No.of favourable outcomes = 200 × 1 = 200
P (E) = no.of favourable outcomes / total no.of possible outcomes
= 200/800
= 1/4
Answer:
Standard error = 0.4
Step-by-step explanation:
Step 1
We find the Standard Deviation
The formula = √(x - mean)/n - 1
n = 15
Mean = 1.93 hours
= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1
= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1
= √2.352380952
= 1.533747356
Step 2
We find the standard error
The formula = Standard Deviation/√n
Standard deviation = 1.533747356
n = 15
= 1.533747356/√15
= 1.533747356 /3.87298334621
= 0.39601186447
Approximately = 0.4
Therefore, the standard error is 0.4
I think its 200%
Best Of Luck!!!!
