This equation has x terms on both the left and the right. To solve an equation like this, you must first get the variables on the same side of the equal sign. You can subtract 5x on each side of the equal sign, which gives a new equation: x + 5 = 10. hope this helps

A set average city temperatures in August are normally distributed with a mean of 21.25 degrees Celsius and a standard deviation

Ainat [17]

Answer:

The proportion of temperatures that lie within the given limits are 10.24%

Step-by-step explanation:

Solution:-

- Let X be a random variable that denotes the average city temperatures in the month of August.

- The random variable X is normally distributed with parameters:

mean ( u ) = 21.25

standard deviation ( σ ) = 2

- Express the distribution of X:

X ~ Norm ( u , σ^2 )

X ~ Norm ( 21.25 , 2^2 )

- We are to evaluate the proportion of set of temperatures in the month of august that lies between 23.71 degrees Celsius and 26.17 degrees Celsius :

P ( 23.71 < X < 26.17 )

- We will standardize our limits i.e compute the Z-score values:

P ( (x1 - u) / σ < Z < (x2 - u) / σ )

P ( (23.71 - 21.25) / 2 < Z < (26.17 - 21.25) / 2 )

P ( 1.23 < Z < 2.46 ).

- Now use the standard normal distribution tables:

P ( 1.23 < Z < 2.46 ) = 0.1024

- The proportion of temperatures that lie within the given limits are 10.24%

mars1129 [50]

Answer:

The second one represents x = 1

The forth one represents x = 1

They both are correct as they both represent x = 1 and greater than 0.5 minus -1 will equal 30-0.5 it is telling you that when we minus 1 from 30 it (x) cannot be greater than 0.5
