Answer:

<em>See the Venn diagram attached</em>

<u>Numbers given:</u>

  • <em>Total</em>: 100
  • Either a cat of a fish: 70
  • Cat: 46
  • Cat and fish: 16

<u>Neither a cat or a fish:</u> 100 - 70 = 30

<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8

<u>Required probabilities are:</u>

  • a) P(neither) = 30/100 = 0.3
  • b) P(f) = (16 + 8)/100 = 0.24
  • c) P(f not c) = 8/100 = 0.08

In the figure below, L N equals 4 x minus 7 and M O equals 2 x plus 13. For which value of x is the figure a rectangle?
Georgia [21]

For this case we have the following data:


LN = 4x-7

MO = 2x + 13

So that the figure can be a rectangle, its diagonals must be equal, that is, LN = MO

In this way we have:


4x-7 = 2x + 13

Clearing x we have:

4x-2x = 13 + 7 \\2x = 20

x=\frac{20}{2} \\x = 10

Thus, x must be equal to 10 so that the figure is a rectangle.


Answer:


x = 10

Option A

PLEASE HELP ASAP!!!
Mariana [72]

Answer:

<h3>C. (a, b)</h3>

Step-by-step explanation:

The formula of a midpoint:

M\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)

We have A(0, 0) and C(2a, 2b). Substitute:

x=\dfrac{0+2a}{2}=\dfrac{2a}{2}=a\\\\y=\dfrac{2b+0}{2}=\dfrac{2b}{2}=b

M(a, b)
