CAN ANYONE HELP ME THANKS FOR BRAINLIEST ANSWER? Find slope ( simplest form) parallel to the line 4x+2y=3

tino4ka555 [31]

Answer:

Slope = -2

Step-by-step explanation:

You want to get it to the slope intercept form first.

2y = -4x + 3

Divide by 2

y = -2x + 3/2

Parallel means in the new slope intercept form there will still be -2x.

y = -2x + b (enter in points ( 0, 1.5 ) )

1.5 = 0 + b

b = 1.5

y = -2x + 1.5 ( just an example of a line parallel to 4x + 2y = 3 )

During the semester, all the students in a statistics class kept track of the number of mailings they received from a predatory

Verdich [7]

Answer:

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

$n_{75} = 0.75* 9= 6.75\approx 7$

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

$x_{75} = 18$

Step-by-step explanation:

For this case we have the following data:

16 17 11 21 15 14 17 18 19

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

$x_{75} = 18$

3(2x + 6) - 4x = 2(5x - 2) + 6

sp2606 [1]

Answer:

x = 2

Step-by-step explanation:

$3(2x + 6) - 4x = 2(5x - 2) + 6 \\ 6x + 18 - 4x = 10x - 4 + 6 \\ 2x + 18 = 10x + 2 \\ 18 - 2 = 10x - 2x \\ 16 = 8x \\ x = \frac{16}{8} \\ \huge \: \red { \boxed{x = 2}}$
