Both of these types of rocks would be susceptible to weathering and erosion.
Thus, the answer would be:
C. Both igneous rocks and metamorphic rocks.
Answer:
1092.50 account value
142.50 interest
Step-by-step explanation:
to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years
now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $
the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$
Answer:
Hence the confidence interval is ( 0.6745, 0.7422).
Step-by-step explanation:
Now the given are
Sample size = n = 1200
x = 850
Sample proportion is
We have to construct 99% confidence interval for the population proportion.
Formula Used:
Here E is a margin of error.
Zc = 2.58
So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)
= ( 0.6745 , 0.7422).
X= 1,-3 If you factor equation you get x-1=0 and x+3=0
