Answer:

Step-by-step explanation:

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4 Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is 2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line

Hope this helps

You just have to see where the x is & count up or down in till you get to your number

Consider the equation. Which graph shows a line that is perpendicular to the line defined by the given equation? A. In a linear

Nikolay [14]

The graph second represents the line that is perpendicular to the line y = 4x - 2 option (B) is correct.

<h3>What is the slope?</h3>

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

The question is incomplete:

The complete question is:

Consider the equation y = 4x - 2 Which graph shows a line that is perpendicular to the line defined by the given equation?

Please refer to the attached picture.

The given line:

y = 4x - 2

The slope of the line m = 4

The slope of the line which is perpendicular to the above line:

M = -1/4 = -0.25

The graph second has a slope of -0.25

$\rm y\ -2\ =\ \dfrac{\left(2-0.5\right)}{-4-2}\left(x+4\right)$

y - 2 = -0.25x - 1

y = -0.25x + 1

Thus, the graph second represents the line that is perpendicular to the line y = 4x - 2 option (B) is correct.

A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?

antoniya [11.8K]

10 cents, cause the {ball +$1.00=$1.10} subtract $1 from both sides the ball=$0.10

A survey showed that 77% of us need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. 13 adults are randomly

earnstyle [38]

Using the binomial distribution, it is found that the probability that at least 12 of the 13 adults require eyesight correction is of 0.163 = 16.3%. Since this probability is greater than 5%, it is found that 12 is not a significantly high number of adults requiring eyesight correction.

For each person, there are only two possible outcomes, either they need correction for their eyesight, or they do not. The probability of a person needing correction is independent of any other person, hence, the binomial distribution is used to solve this question.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

A survey showed that 77% of us need correction, hence p = 0.77.

13 adults are randomly selected, hence n = 13.

The probability that at least 12 of them need correction for their eyesight is given by:

$P(X \geq 12) = P(X = 12) + P(X = 13)$

In which:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{13,12}.(0.77)^{12}.(0.23)^{1} = 0.1299$

$P(X = 13) = C_{13,13}.(0.77)^{13}.(0.23)^{0} = 0.0334$

Then:

$P(X \geq 12) = P(X = 12) + P(X = 13) = 0.1299 + 0.0334 = 0.163$

The probability that at least 12 of the 13 adults require eyesight correction is of 0.163 = 16.3%. Since this probability is greater than 5%, it is found that 12 is not a significantly high number of adults requiring eyesight correction.
