12 (x-4)=6 (x-1)
12x - 48 =6x + 6
12x - 6x = 6 + 48
6 = 54

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n equals 125n=12

sesenic [268]

<span>This is a matter of knowing the formulas involving the binomial distribution: Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>

Isa finished 30% of his homework in 27 minutes. How many more minutes will it take Isa to complete his homework, assuming that h

Brilliant_brown [7]

Answer:

90 Minutes

Step-by-step explanation:

If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount

30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.

(a) Find z such that the proportion of observations that are less than z in a standard normal distribution is 0.36. (Enter your

Alisiya [41]

Answer:

a) z = -0.358

b) z = 0.358

Step-by-step explanation:

We are given a standard normal distribution.

a) We have to find the value of z such that the proportion of observations that are less than z in a standard normal distribution is 0.36.

That is,

$P(Z$

This value will be calculated with the help of a standard normal table.

From standard normal table we have,

$P(z\leq -0.358) = 0.36$

Thus, for z equal to -0.358 the proportion of observations that are less than z in a standard normal distribution is 0.36

b) We have to find the value of z such that 36% of all observations from a standard normal distribution are greater than z.

$P(Z>z) = 0.36$

This value will be calculated with the help of a standard normal table.

$= 1 -P( Z > z)=1 - 0.36 = 0.64$

$P( z \leq z)=0.64$

Calculation the value from standard normal z table, we have,

$P(z \leq 0.358) = 0.64$

Thus, 36% of all observations from a standard normal distribution are greater than z equal to 0.358

In the figure below, if a = 4 and b = 20, then c is approximately 19.45. true or false

asambeis [7]

False. To find C, we can use the equation:

a^2 + b^2 = c^2

4^2 + 20^2 = c^2

c^2 = 416

c = approximately 20.40
