Answer:

The probability that the pair consists of a female junior and a male sophomore is 0.096

Step-by-step explanation:

No of male juniors=4

No of female juniors=10-4=6

No of female sophomores=5

No of male sophomores=13-5=8

As per question,

Probability that the pair consists of a female junior and

a male sophomore =\frac{6C1\times8C1}{32C2}=0.096

Therefore, the probability that the pair consists of a female junior and a male sophomore is 0.096

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is one leg
  • b is another leg
  • c is hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

a = 19

b = <em>x</em>

c = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    19² + x² = 21²
  2. Isolate <em>x</em> term:                      x² = 21² - 19²
  3. Exponents:                           x² = 441 - 361
  4. Subtract:                               x² = 80
  5. Isolate <em>x</em>:                               x = √80
  6. Simplify:                                x = 4√5

Graph the equation: x = y^2 - 2
Lesechka [4]
Draw a cartesian plane, create a graph with the equation x = y^2 - 2
then substitute numbers into the equation so that it is true, to find points on the graph, e.g. substitute y with 1, you get 
x = 1^2 - 2
x = 1 - 2 = -1, so when y = 1, x = -1, this point is (-1, 1)

for the next substitute y with 2,
x = 2^2 - 2
x = 4 - 2 = 2, the point is (2, 2)
you might want to try negative values of y 
y = -1, x = (-1)^2 - 2
x = -1 the point is (-1,-1)

then plot the points on the graph
