Juan hikes up a mountain. He hikes back down at a constant rate. The table shows Juan's elevation at each hour after he begins h
Dimas [21]

The linear function that describes Juan's elevation during his descent is:

B. y = -1460x + 7500.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, each hour, the height decays by 1460, hence the slope is of m = -1460, then:

y = -1460x + b.

The y-intercept is found considering that when x = 1, y = 6040, hence:

b = 6040 + 1460 = 7500.

Which means that option B is correct.

13. What is the y-intercept of the line that passes through (4, 1) and has a slope of<br> -2?
Len [333]

Answer:

The y-intercept of the line is 9.

Step-by-step explanation:

y-y1=m(x-x1)

y-1=-2(x-4)

y-1=-2x+8

y=-2x+8+1

y=-2x+9

y=mx+b where m=slope and b=y-intercept

katrin [286]

The value of the variable is 4√5. Then the correct option is C.

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

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The similar triangles are shown in the diagram.

16 / x = x / 5

    x² = 16 × 5

      x = 4 √5

Then the value of the variable is 4√5.

Then the correct option is C.

More about the triangle link is given below.

Amy, a nature photographer, randomly sampled photographs she took within the last year. She wanted to find out how many of her p
Sveta_85 [38]

The Constructed  confidence interval for the proportion of her photographs taken within the last year contained flowers is

CI\ E(0.57,0.65)

From the question we are told that:

The proportion of photographs that had flowers P= 0.61

Margin of error of M.E= 0.04

Generally, the equation for Confidence interval for proportion is mathematically given by

CI=0.61 \pm 0.04P \pm M.E

Therefore Confidence interval is

CI=0.61 \pm 0.04

And can also be written as

CI\ E((0.61+0.04),0.61-0.04))

CI\ E(0.57,0.65)

In conclusion the Confidence interval is

CI\ E(0.57,0.65)
