80 times could Kaitlyn expect to pull out a blue chip.

<u>Step-by-step explanation</u>:

  • The total number of chips in the bag = 7 white+5 red+ 8 blue = 20 chips.
  • Probability (blue chip) = number of blue chips / total chips

P(blue) = 8/20

She does this 200 times.

P(blue) for 200 times = (8/20)\times200 = 80.

Determine the intercepts of the line. yy y y -intercept: (\Big( ( left parenthesis ,, , comma )\Big) ) right parenthesis xx x x
BlackZzzverrR [31]

Question:

Give all the x and y intercept of the function

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30}

Answer:

The x intercepts are x = 5 and x = -4

The y intercept is at y = -2

Step-by-step explanation:

Factorizing the numerator of the expression we find the x intercepts as follows;

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30} =\frac{3(x-5)(x+4)}{2x^3 + 2x^2-34x+30}

Therefore, the x intercept are

x = 5 and x = -4

To find the y intercept, we put x = 0 to get y = -2

Therefore, the y intercept is at y = -2

Factorizing the denominator we find the values for which the equation is undefined

2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives

x = 1, 3 and -5.

How can you show two figures are congruent?
galina1969 [7]

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

What in mathematics is the congruent?

  • It is claimed that two figures are "congruent" if they can be positioned exactly over one another.
  • Both the shape and size of the bread slices are same if you lay one slice on top of the other.
  • Congruent refers to having precisely the same form and size.

Use the Third Angles Theorem for  two figures are congruent.

When two of a triangle's angles match up with two of another triangle's angles, the third angle must likewise match up.

If at least two sides and one angle of two triangles are similar, then the triangles are congruent.
