Solve 4(-2x + 7) = 24 for x
tamaranim1 [39]

Answer:

x = 1/2

Step-by-step explanation:

brainlest please

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4*(-2*x+7)-(24)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 4 • (7 - 2x) -  24  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  4 - 8x  =   -4 • (2x - 1)

Equation at the end of step  3  :

 -4 • (2x - 1)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    2x-1 = 0

Add  1  to both sides of the equation :

                     2x = 1

Divide both sides of the equation by 2:

                    x = 1/2

For a standard normal distribution, which of the following expressions must always be equal to 1?
Valentin [98]

Option D, For a standard normal distribution, the expression that is always equal to 1 is P(z ≤ -a) + P(-a≤z≤a) + P(Z≥a).

<h3>What is standard normal distribution?</h3>

A standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1.

For a standard normal distribution, the total area of a curve is always equal to 1.

total area = P(z≤-a)+P(-a≤z≤a)+P(Z≥a) = 1

Thus, for a standard normal distribution, the expression that is always equal to 1 is P(z ≤ -a) + P(-a≤z≤a) + P(Z≥a).

g100num [7]

Answer:

$7,213

Step-by-step explanation:

The computation of the total earnings for June and July is given below:

For June

= $2,000 + 2.7% × $51,000

= $2,000 + $1,377

= $3,377

And, for July

= $2,000 + $68,000 × 2.7%

= $2,000 + $1,836

= $3,836

So, the total earnings is

= $3,377 + $3,836

= $7,213
