Answer:
y = 12
Step-by-step explanation:
Given
Green = 28
Red = 35
Yellow = y
Prediction of yellow = 16 of 100
Required
Determine y
First, we need to calculate the probability of yellow.
Probability of yellow =
Probability = Yellow/Total
Where
Total = Yellow + Red + Green
Total = y + 35 + 28
Total = y + 63
So,
Probability = y/(y + 63)
Also, the prediction of yellow is 16 out of 100.
Represent this as probability.
Probability = 16/100
Equate both expressions to solve for y
y/(y + 63) = 16/100
y/(y + 63) = 0.16
Multiply both sides by (y + 63)
y = 0.16(y + 63(
y = 0.16y + 10.08
Collect like terms
y - 0.16y = 10.08
0.84y = 10.08
Solve for y
y = 10.08/0.84
y = 12
Answer:
75x² + 10x - 2
Step-by-step explanation:
Substitute x = 5x into f(x), that is
f(5x) = 3(5x)² + 2(5x) - 2
= 3(25x²) + 10x - 2
= 75x² + 10x - 2
Answer:
b
Step-by-step explanation:
you add 80 and 16 together and subtract it from 180
so you do 180-96
and you get 84
Answer:
Statistical inference refers to using a sample of measurements and making generalizations about the important aspects of a population.
Step-by-step explanation:
Statistical inference:
- Statistical inference is use of statistics to draw conclusions about some unknown parameters of a population based on a random sample from that population.
- With the help of sample statistic of a sample drawn randomly from the population, we approximate some properties of population.
- This is known as statistical inferences.
- It is an important method to analyze properties of a population based on the sample.
