Simple....

you have: 6z+10=4z+19

Isolate the variable...

6z+10=4z+19
-4z      -4z

2z+10=19

2z+10=19
     -10 -10

2z=9

z=4.5

Thus, your answer.

Plz help asap !! The high school jazz band is selling homemade leather bracelets at a local craft fair to raise money for a trip
torisob [31]

Answer:

y = 2x - 200

Step-by-step explanation:

The function type that would model this relationship is linear because for each bracelet sold, the jazz band would increase their profit by $2.  Since it has a consistent rate, it is linear.  Using the slope-intercept formula of y = mx + b, where 'm' is the rate and 'b' is the initial value, you can use $2 for the rate or cost per bracelet and -$200 for the initial value or cost of supplies:

y = 2x - 200, where '2' is the cost per bracelet, 'x' the number of bracelets sold, '-200' is the cost for supplies and 'y' is the profit.

The following correlations were computed as part of a multiple regression analysis that used education, job, and age to predict
erma4kov [3.2K]

Answer:

Job has the weakest association with the dependent variable income.

Step-by-step explanation:

The correlation coefficient is used to determine the the strength and direction of the relationship between two variables.

It is denoted by <em>r</em> and the value of <em>r</em> ranges from -1.00 to 1.00.

The correlation data provided is as follows:

                    Income    Education    Job     Age

Income         1.000      

Education     0.677        1.000

Job                0.173         -0.181        1.000

Age               0.369        0.073        0.689   1.000

The dependent variable is the income.

And the variables Education, Job and Age are independent variables.

The correlation between Income and Job is 0.173.

This is the lowest correlation coefficient between the dependent and independent variable.

Thus, Job has the weakest association with the dependent variable income.

Find the area of a trapezoid with bases 2ft and 3ft and height 1/3 foot. Round your answer to the nearest tenth
amid [387]

Answer:

Area = 5/6 of a foot^2

Step-by-step explanation:

Formula

Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2

Givens

  • b1 = 2 feet
  • b2 = 3 feet
  • h = 1/3 foot

Solution

Area = 1/2(2 + 3)*1/3

Area = 1/2(5)* 1/3

Area = (1/2 * 1/3) * 5

Area = (1/6) * 5

Area = 5/6
