Answer:

Point slope form : y-3=\frac{1}{2}(x-2)

Slope intercept form: y=\frac{1}{2}(x)+2

Standard form : -x+2y=4

Step-by-step explanation:

From the given graph it is clear that the line is passing through the points, (-4, 0), (-2, 1), (0, 2), and (2, 3).

If a line passes through two points (x_1,y_1) and (x_2,y_2), then the equation of line is

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Let as consider any two points of the line:  (2, 3) and (0, 2).

The equation of line is

y-3=\frac{2-3}{0-2}(x-2)

y-3=\frac{1}{2}(x-2)

The point slope form of the line is y-3=\frac{1}{2}(x-2).

y-3=\frac{1}{2}(x)-\frac{1}{2}(2)

y-3=\frac{1}{2}(x)-1

Add 3 on both sides.

y=\frac{1}{2}(x)-1+3

y=\frac{1}{2}(x)+2

Therefore the slope intercept form of the line is y=\frac{1}{2}(x)+2.

Multiply both sides by 2.

2y=x+4

-x+2y=4

Therefore, the standard form of the line is -x+2y=4.

The functions below represent the amounts of water released from two reservoirs over x weeks:
solong [7]

Answer:

  • h(x) = -2x^2 -x +3
  • Reservoir A releases the same amount of water as Reservoir B over 1 week

Step-by-step explanation:

<u>Given</u>:

  f(x) = x^2 -7x +5

  g(x) = 3x^2 -6x +2

  h(x) = f(x) -g(x)

<u>Find</u>:

  h(x)

  h(1)

<u>Solution</u>:

The expression for h(x) is found by evaluating its definition:

  h(x) = (x^2 -7x +5) -(3x^2 -6x +2)

  h(x) = x^2(1 -3) +x(-7 -(-6)) +(5 -2)

  h(x) = -2x^2 -x +3

Then h(1) is found by substituting 1 for x:

  h(1) = -2(1^2) -(1) +3 = -2 -1 +3

  h(1) = 0 . . . . difference in release amounts after 1 week is 0

The true statements are ...

  • h(x) = -2x^2 -x +3
  • Reservoir A releases the same amount of water as Reservoir B over 1 week

A study involves a population of 400 tall women. This population has a mean height of 179.832 cm and a standard deviation of 12.
Fofino [41]

Answer:  0.0386

Step-by-step explanation:

Given: The population of 400 tall women has a mean height(\mu) of 179.832 cm and a standard deviation(\sigma) of 12.192 cm.

Let X be a random variable that represents the height of woman.

Sample size : n= 50

The probability that the mean for this sample group is above 182.88 will be :

P(\overline{X}>182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z>1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z

Hence, Required probability =  0.0386
