1/3 is the correct answer simplified
<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>

Answer:
A ≈ 5.6
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
× PQ × PR × sin P
= 0.5 × 5.2 × 2.8 × sin50°
≈ 5.6 ( to 1 dec. place )
Answer:
75
Step-by-step explanation:
Let n be the unknown number
- 4+3/5n=49
- Isolate variable- 3/5n=45
- Multiply by 5/3- n=75
