Need help with this ( finding slope ) plz

Mathematics
1 answer:
loris [4]3 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 340) and (x₂, y₂ ) = (4, 292) ← 2 ordered pairs from table

m = \frac{292-340}{4-0} = \frac{-48}{4} = - 12

(0, 340 ) → gives the y- intercept b = 340

The equation is of the form

y = mx + b ( m is the slope and b the y- intercept ), thus

y = - 12x + 340

Which score has a higher relative position, a score of 92 on a test with a mean of 71 and a standard deviation of 15, or a score
slava [35]

solution:

a score of 92 has z score of

z=\frac{x-μ}{σ}=\frac{92-71}{5}=1.40

a score of 688 has z score of

z=\frac{x-μ}{σ}=\frac{688-493}{150}=1.30

a score of 92 is better because its z score is higher

By using trigonometric relations, we will see that x = 9.97°.

<h3>How to find the missing angle?</h3>

First, we need to find the bottom cathetus of the smaller triangle, we will use the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Where:

  • θ = 26°
  • Adjacent cathetus = k
  • Opposite cathetus  = 55ft.

Replacing that we get:

Tan(26°) = 50ft/k

Solving this for k, we get:

k = 55ft/tan(26°) = 112.8 ft

Now, we can see that the longer triangle adds 200ft to this cathetus, so now we will have:

  • angle = x
  • opposite cathetus = 55ft
  • adjacent cathetus = 112.8ft + 200ft = 312.8ft.

Then we have:

Tan(x) = (55ft/312.8ft)

Using the inverse tangent function in both sides, we get:

x = Atan(55ft/312.8ft) = 9.97°
