What number has 2 more tens than 40 and the same number of ones as 18

1 answer:

5 0

The answer is 68.
To solve 2 more tens than 40, you add 20 to 40, which is 60.
To solve for the same number of ones as 18, then it would only be 68.

Hope this helps!!

mylen [45]

Answer:

F(10) = P(x = 10) = 0.3

F(5) = P(x = 5) = 0.4

F(1) = P(x = 1) = 0.3

Step-by-step explanation:

Given the following :

Probability estimates given:

Very successful = 0.3

Moderately successful = 0.4

Unsuccessful = 0.3

Yearly revenue (X) :

Very successful = $10 million

Moderately successful = $5 million

Unsuccessful = $1 million

The probability mass function of X:

f(x) = probability of each valie of x

When x = 10:

F(10) = P(x = 10) = 0.3

When x = 5:

F(5) = P(x = 5) = 0.4

When x = 1:

F(1) = P(x = 1) = 0.3

ipn [44]

Answer:

The standard error of the sample mean is _17.677_ psi.

Step-by-step explanation:

<u>Explanation</u>:-

A random sample of n = 8 specimens is collected.

Given sample size is n = 8

Given mean of the population 'μ' = 2500 psi

standard deviation 'σ' = 50 psi

Let x⁻ is the mean of the observed sample

Standard error of the sample mean = $\frac{S.D}{\sqrt{n} }$ ...(i)

Given Population of standard error (S.D) 'σ' = 50 psi

Now substitute all values in (i)

$S.E = \frac{50}{\sqrt{8} } =17.677$

<u>Conclusion</u>:-

The standard error of the sample mean is _17.677psi.
