Answer:
Total = 30.75cm squared
Step-by-step explanation:
Area of trapezium = (A+b)h divided by 2 = 15cm squared
area of triangle 1 = 1/2 x b x h = 3 cm squared
Area of triangle 2 = 2.25 cm squared
Area of trapezium at the bottom = 10.5 cm squared
Total = 30.75cm squared

Answer:
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given mean of the Population = 500
Given standard deviation of the Population = 50
Let 'X' be the random variable in normal distribution
Given X = 600
![Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7Bx-mean%7D%7BS.D%7D%20%3D%20%5Cfrac%7B600-500%7D%7B50%7D%20%3D%20%5Cfrac%7B100%7D%7B50%7D%20%3D2)
<u><em>Step(ii)</em></u>:-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = P(z≥2)
= 0.5 - A(2)
= 0.5 -0.4772
= 0.0228
<u><em>Final answer</em></u>:-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228
Answer:
1.70
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 4.25 × 60/100
Discount = 4.25 x 0.6
You save = $2.55
Final Price = Original Price - Discount
Final Price = 4.25 - 2.55
Final Price = $1.70
