Answer:
The answer to this question is within 2 stabdard deviations
Step-by-step explanation:
to get the score of 85 you got to add the deviation value to the mean whuch creates the deviation. do that multiple times and you get a multiple deviation
72+8=80+8 is 88
88 is greater than 85 so a test score of 85 is within 2 standard deviations of the mean
Answer:
Option 1
Step-by-step explanation:
(0×-5)+(1×-4) = -4
(1×-5)+(0×-4) = -5
Answer:
here what to do
Step-by-step explanation:
Since the volume of a cone is pi the radius squared times the height divided by 3. If you know the diameter,you simple divide by 2
The formula of the Simple Interest is:
I=PRT
P for Principle Amount ($1200)
R for Rate (5%=

= 0.05)
T for Time in years (4 years)
I = 1200 × 0.05 × 4
= $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
Answer:
= One-half more than three-fourths of a number
= Three-fourths minus one-half of a number
= three-fourths minus the sum of a number and one-half
Step-by-step explanation:
Suppose x be an unknown number.
∵ 3/4th of a number = 
= One-half more than three-fourths of a number
Now, half of a number = 
= Three-fourths minus one-half of a number
Sum of a number and one-half = 
= three-fourths minus the sum of a number and one-half
