Answer quickly please.
jeka57 [31]

Answer:

8.333333

Step-by-step explanation:

 3x+2(4+6x)=133

  3x+8+12x=133                      First I distibuted the 2 too the 4 and 6x

15x+8=133                                 Then I added the x es 3x and 12x

15x+8-8=133-8                         Then I subracted 8 from both sides

15x=125                                    That leaves with this

 15x/15=125/15                          Now I divide 15 from both sides to isolate x

x= 8.33333                                 that is the answer

                             check

                  3x+2(4+6x)=133

                 3*8.333333+2(4+6*8.333333)=133

                  24.999999 +2(4+ 49.999998)=133

                    24.999999+2( 53.999998)=133

                         24.999999+107.999996=133

                              132.999995=133

The weights of cars passing over a bridge have a mean of 3,550 pounds and standard deviation of 870 pounds. Assume that the weig
Annette [7]

Answer:

0.24315

Step-by-step explanation:

Using the z score formula to solve this question

z = (x - μ) / σ,

Such that:

x = raw score

μ = population mean

σ = population standard deviation.

From the question:

x = 3000

μ = 3550

σ = 870

z = (3000 - 3550) / 870

z = -550/870

z = -0.6962

Using the z score table as well as probability calculator(as requested in the question to find the z score)

The probability of having less than 3000 is obtained as:

P(x<3000) = 0.24315

The total number of gallons of water in a tank, w, after t minutes is given in this table and the plot.
Katyanochek1 [597]

The equation showing the relationship between w and t is w = 4t

From the table, we have the following points:

(0,0) and (1,4)

Start by calculating the slope (m)

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{4 -0}{1 -0}

Simplify the numerator and the denominator

m = \frac{4}{1}

Divide 4 by 1

m = 4

The equation is then calculated as:

w = m(t - t_1) + w_1

This gives

w = 4(t - 0) + 0

Simplify

w = 4t

Hence, the equation is w = 4t
