Answer:
2y I think ( I am not sure tho)
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean
= 70 inches
Standard deviation
= 3 inches
Average basket ball player
= 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
Base = 12÷2
= 6
slant height = a
a^2 = 6^2 + 8^2
a^2 = 100
a = 10 cm
im not sure but its 80 or 65
Ok so first you would create a proportion.
8/x=4/1. Next you cross multiply and divide,
1 • 8÷4=x. Ratios are fractions with the first number being the numerator and the second being the denominator. If you think of it this way, you just find an equivalent fraction. Your answer would be 8:2 because in your proportion x=2.
