Since there were 6 slices, and he ate 1/3, 6*1/3= 2, so he ate 2 slices
Answer:
267
Step-by-step explanation:
We are given the expression: 6 (d - f) +f
The value of the expression when d= 47 and f = 3 is :
6 (47 - 3) +3 = 6×(44) + 3 = 264 + 3 = 267
=267
Last angle is 122 if its a triangle
Answer:
C
Step-by-step explanation:
If the parent function is function and then
- the graph of the function is translated a units to the right graph of the parent function;
- the graph of the function is translated a units to the left graph of the parent function;
- the graph of the function is translated a units up graph of the parent function;
- the graph of the function is translated a units down graph of the parent function.
In your case, the grapgh of the function is translated 2 units up the graph of the function
Answer:
a. Mean = 20
Sd = 4
b. Probability of X = 20 = 0.1960
Step-by-step explanation:
we have
n = 25
p = 80% = 0.8
mean = np
= 0.8 * 25
= 20
standard deviation = √np(1-p)
= √25*0.8(1-0.8)
=√4
= 2
probability that exactly 20 favours ban
it follows a binomial distribution
= 25C20 × 0.8²⁰ × 0.2⁵
= 53130 × 0.01153 × 0.00032
= 0.1960
Probability of X = 20 = 0.1960
