Answer:

see explanation

Step-by-step explanation:

(6)

The opposite sides of a parallelogram are congruent , so

10x + 6 = 4x + 18 ( subtract 4x from both sides )

6x + 6 = 18 ( subtract 6 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

--------------------------------------------------------

(7)

The opposite angles of a parallelogram are congruent , so

9z - 42 = 5z + 8 ( subtract 5z from both sides )

4z - 42 = 8 ( add 42 to both sides )

4z = 50 ( divide both sides by 4 )

z = 12.5

------------------------------------------------------------

(8)

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the 3 given angles from 360° for 4th angle

4th angle = 360° - (49 + 111 + 133)° = 360° - 293° = 67°

-----------------------------------------------------------

(9)

Opposite sides are congruent , so

XZ = WY = 22

YX = ZW = 31

You order fourteen burritos to go from a Mexican restaurant, six with hot peppers and eight without. However, the restaurant for

Genrish500 [490]

Answer:

0.578

Step-by-step explanation:

If you pick three burritos at random, find the probability of the given event. (Round your answer to three decimal places.)

Given that there are 14 orders at the ratio by of:

6 with hot peppers

8 without hot peppers

At most two have hot peppers.

Binomial Problem with n = 3 ; p(hot) = 6/8

P(0<= x <=2) = 1 - P(x = 3)

= 1 - (6/8)^3

= 1 - ( 3/4 )^3

= 1 - ( 27/64 )^3

= 1- (37/64)

= 1 - 0.421875

= 0.578125

= 0.578

Write in slope-intercept form an equation of a line that passes through the given points. (1,6) and (3,2)

Margaret [11]

Answer: y = -2x + 8

Step-by-step explanation:

To find the equation of the line , we will use the formula:

$\frac{y_{2}- y_{1}}{x_{2}- x_{1}}$ = $\frac{y-y_{1}}{x - x_{1}}$

From the question

$x_{1}$ = 1

$x_{2}$ = 3

$y_{1}$ = 6

$y_{2}$ = 2

substituting into the formula , we have

$\frac{2 - 6}{3 - 1}$ = $\frac{y - 6}{x - 1}$

$\frac{-4}{2}$ = $\frac{y - 6}{x - 1}$

cross multiplying , we have

2(y-6) = -4(x-1)

Expanding , we have

2y - 12 = -4x + 4

Adding 12 to both sides , we have

2y = -4x + 16

dividing through by 2 , we have

y = -2x + 8

Therefore , the equation of the line is given as

y = -2x + 8
