Answer:
c. approximately 90.07%
Step-by-step explanation:
We need to calculate z-statistic of 30 inches of rain in the normal distribution with an average of 35.4 inches of rain each year, and a standard deviation of 4.2 inches.
z score can be calculated using the formula
z=
where
- M is the average rain in inches (35.4)
- s is the standard deviation (4.2)
using the numbers we get z=
≈ −1,286
Then percentage of years does Ithaca get more than 30 inches of rain is
P(z>-1.286) =1- P(z<-1.286)=1-0.0993 ≈0.9007 or 90.7%
Answer:
The final answer is 11.9
Step-by-step explanation:
14 x 6 = 84
84/5 = 16.8
16.8 - 4.9 = 11.9

Divide 3.24 with 6 and the answer will be found
$0.54
The correct answer is: [A]: " 2x³ + 7x² + 12x − 8 " .
______________________________________________________
Explanation:
__________________________________________
Given:
__________________________________________
" (x² + 4x + 8) (2x − 1) " ; Find the product:
↔ " (2x − 1) (x² + 4x + 8) " ;
__________________________________________
Note: " (a + b) (c + d + e) = ab + ad + ae + bc + bd + ae " .
__________________________________________
→ " (2x − 1) (x² + 4x + 8) =
(2x * x²) + (2x * 4x) + (2x *8) + (-1 * x²) + (-1 * 4x) + (-1 * 8) ;
= 2x³ + 8x² + 16x + (-1x²) + (-4x) + (-8) ;
= 2x³ + 8x² + 16x − x² − 4x − 8) ;
→ Combine the "like terms" :
+ 8x² − x² = + 7x² ;
+ 16x − 4x = + 12x ;
_______________________________________________________
And rewrite the expression:
_______________________________________________________
→ " 2x³ + 7x² + 12x − 8 " ;
→ which is: Answer choice: [A]: " 2x³ + 7x² + 12x − 8 " .

Sqrt(5/3)
and
sqrt(0/6)
many square roots are irrational numbers as long as they are not a perfect square
|-3| becomes positive 3
0.6 can be converted into a fraction 6/10
