4) The radius of circle is 9 cm and diameter is 18cm.
Answer:
Step-by-step explanation:
Given is the graph bell shaped.
We have to find the variance of the data
We see that the graph looks like a normal distribution curve symmetrical about x=19
Hence mean =19
Since we know maximum area covered within 3 std deviations on either side of mean, we can calculate 6 sigma value from the graph
Extreme left x value = 14 and right = 24
Hence 6 times std dev =24-14 =10
So std deviation = 10/6 =5/3
Variance = 25/9
The formula is
A=P(1+r/n)^nt
A future value?
P present value 1500
R interest rate 0.04
N compounded quarterly 4
T time 2 years
A=1,500×(1+0.04÷4)^(4×2)
A=1,624.29
So the answer is B
Hope it helps!
Answer:
is part 1 and part 3 the same, no
Step-by-step explanation:
You can do a proportion: 75/15 = x/100
you then do 100x75 and the divide by 15 and get 500.
15% of $500 is $75 so the sale price would be $425 I believe.
