0.36 divided by 324 is 0.00111111
Answer:
A
Step-by-step explanation:
First, find Neeta's total height in inches:
4 feet in inches is 4*12, which equals 48
Add the other 7 inches of her height to get 55 inches.
Then, subtract her initial height from her current height.
55 - 17 = 38. That is how many inches she has grown. Convert that to feet by dividing 38 by 12.
You get about 3.16, which is over 3 feet. So A is the correct answer.
Final result : -3
Step by step solution :Step 1 : 3 - a Simplify ————— 21 Equation at the end of step 1 : (a - 3) (3 - a) ——————— ÷ ——————— 7 21 Step 2 : a - 3 Simplify ————— 7 Equation at the end of step 2 : (a - 3) (3 - a) ——————— ÷ ——————— 7 21 Step 3 : a-3 3-a Divide ——— by ——— 7 21
3.1 Dividing fractions
To divide fractions, write the divison as multiplication by the reciprocal of the divisor :
a - 3 3 - a a - 3 21 ————— ÷ ————— = ————— • ——————— 7 21 7 (3 - a)
3.2 Rewrite (3-a) as (-1) • (a-3) Canceling Out : 3.3 Cancel out (a-3) which now appears on both sides of the fraction line.
Final result : -3
Answer:
Lowest score needed=4.92
Step-by-step explanation:
Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%
For area of 15% we have Z= -1.04
Thus we have

Applying values we get

Thus lowest score needed = 4.92
