Answer:
What is the probability that you will finish this quiz in 23.84 minutes or less?
0.03593
Write your answer as a percentage with 2 decimals
= 3.59%
Step-by-step explanation:
The z score formula is given as:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean = 26 minutes
Standard deviation = 1.2 minutes.
The probability that you will finish this quiz in 23.84 minutes or less(≤) is calculated as:
z = (x-μ)/σ
z = 23.84 - 26/1.2
z = -1.8
Probability value from Z-Table:
P(x ≤ 23.84) = 0.03593
Converting to percentage
0.03593 × 100
= 3.593
Approximately to 2 decimal places = 3.59%
1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
Answer:
let us assume the 3 digit number be 984
To check weather the number is divisible by 3 and 4 then when should know the divisibility rule of 3 and 4.
A number is said to be divisible by 3 when the sum of each digit of the number is divisible by 3. Example 9+8+4 = 21 is divisible by 3 hence the number is divisible by 3.
A number is said to be divisible by 4 when the last two digit is divisible by 4 like 84 is divisible by 4 hence 984 is divisible by 4.
Answer:
(a, 0)
Step-by-step explanation:
Point S has the same x-coordinate as does Point R: a.
Point S has the y-coordinate 0, as Point S lies on the x-axis.
Correct final answer: (a, 0) represents Point S.
Answer:
VY
Step-by-step explanation:
Coz they all look the same on the sides
