Answer:
The probability is 0.080757
Step-by-step explanation:
We start by calculating the z-score
z-score = (x-mean)/SD/ √n
In this case;
x = 247 , mean = 240, SD = 50 and n = 100
z-score = (247-240)/50/√100
z-score = 7/50/10
= 7/5 = 1.4
So the probability we want to calculate is;
P( x > 1.4)
we can use the standard normal distribution table for this
P(x > 1.4) = 0.080757
Answer:
44 cm²
Step-by-step explanation:
Ar(big rect.) = (4+4)×(4+3)
= 8×7
= 56
Ar. of small rect. = 4×3 = 12
Area of X = 56-12
= 44 cm²
