<span>6 x 298 is the same as (6 x 300) - (6 x 2)
(6 x 300) is the same as (6 x 3 x 100)
So (6 x 3) = 18
(6 x 3 x 100) = (18 x 100) = 1,800
(6 x 2) = 12
So 6 x 298 = 1,800 - 12 = 17,88</span>
Answer:
sin∅ = 0.7311
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
sin∅ = opposite/hypotenuse
Step 1: Find our hypotenuse
14² + 15² = c²
c = √421
Step 2: Find sin∅
sin∅ = 15/√421
sin∅ = 0.731055
So what u do is take -24/8=-3 then u do 4/8=0.5 then u put it together like this -3 - 0.5x =3.5x
Answer:
Percentage of the students scored higher than 89% = 65.87%
Step-by-step explanation:
We need to find the percentage of students who scored higher than 89% given mean = 84 and standard deviation = 5.
We can find the percentage of students who scored higher than 89% by using z-score.
The formula for z-score is:
μ= mean = 84
σ=standard deviation = 5
x= random number = 89
Putting these values, we get
Now, we know that we need to find students who score greater than 89%
so P(X>89) or P(X>1),
finding value of z= 1 which can be easily found using z score tables.
By looking at table we get the value of z = 0.3413
Subtracting the value of z from 1 we get
Percentage of the students scored higher than 89% = 1-0.3413 = 0.6587 or 65.87%
