The probability that the sample proportion is less than 0.80 is mathematically given as P(z<-0.52)
<h3>What is
the probability that the sample proportion is less than 0.80?</h3>
Generally, the equation for probability is mathematically given as
p=82/100
Therefore
p=0.82
q=1-p
q=1-0.82
q=0.18

Answer:
First number is x
Second number is y
Step-by-step explanation:
x = 2y + 1
x + y = 25
(2y + 1) + y = 25
3y = 24
y=24/3
y = 8
x = 2(8) + 1
x = 16+1
x=17

Answer:
20 spaces ahead from starting position.
Step-by-step explanation:
Consider the provided information.
There are 3 colors and 30 spoons.
Each color would be landed on an equal number of time.
That means landing on blue is 10 times out of 30 times.
Landing on red is 10 times out of 30 times.
Landing on orange is 10 times out of 30 times.
As it is given that for blue you need move ahead one space landing on red means the move ahead two spaces and landing on orange means to move back one space
Therefore, the expected position is:
= 10(+1) + 10(+2) + 10(-1)
= 10 + 20 - 10
= + 20
Hence, 20 spaces ahead from starting position.
Answer:
- y = 1.5x
- y = 15 when x = 10
Step-by-step explanation:
A direct variation equation is of the form ...
y = kx
for some constant k. We can arbitrarily choose k=1.5, so our equation is ...
y = 1.5x
For x=10, the value of y is ...
y = 1.5·10 = 15
