You have to convert the fraction so the bottom number is 100
1900: 14/25=56/100
1910: 29/50=58/100
1920: 53/100
1930: 13/20= 65/100
1940: 3/5=60/100
Your answer would be 1930: 13/20= 60/100
I will give you the answer if you give me brainliest answer
B because it’s in order so it. Will make sense if it’s b
Answer:
8 1/6 < x < 20.5.
Step-by-step explanation:
Use the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle is always greater that the third side.
So for triangle to be formed:
4x + 2x - 4 > 45
6x > 49
x > 8 1/6.
Also 2x - 4 + 45 > 4x
41 > 2x
2x < 41
x < 20.5.
Answer:
Explained below.
Step-by-step explanation:
(a)
The mean of the random variable X is:

(b)
The standard deviation of the random variable X is:

(c)
Compute the probability that the average number of cherries in 36 cherry puffs will not be less than 5 as follows:
Since the sample size is large i.e. <em>n</em> > 30, the sampling distribution of sample mean will follow a normal distribution.

(d)
Assume that the two groups are independent.
Then:


Compute the probability that the difference in the average number of cherries will be more than 2 as follows:
