There are only two possible outcomes in the table that satisfy x ≤ -3; either x = -5 or x = -3. Then

P(x ≤ -3) = P(x = -5) + P(x = -3) = 0.17 + 0.13 = 0.3

Find MQ in parallelogram LMNQ .

Liula [17]

Answer:

MQ = 16.4

By the Parallelogram Diagonals Theorem , MP = PQ

So MQ = 2 · MP

Step-by-step explanation:

Parallelogram Diagonals Theorem

The diagonals of a parallelogram bisect each other, i.e. they divide each other into two equal parts.

P is the point of intersection of the diagonals.

Therefore, MP = PQ and LP = PN

If MP = 8.2, then PQ = 8.2

⇒ MQ = 8.2 + 8.2 = 16.4

Please help me :( A standard six-sided die is rolled. What is the probability that it is not a 4?

zmey [24]

Answer:

The answer is 5/6, or .833, 3 repeated.

Step-by-step explanation:

The 4 is only one side of the die, or 1/6 if the surface of the die. So the other part that is left is the other 5/6 of the surface.

Help, I don’t know what I’m doing Trigonometry

spin [16.1K]

Answer:

$\frac{\sqrt{3} }{6}$

Step-by-step explanation:

using the 30- 60- 90 triangle for exact values , then

tan60° = $\sqrt{3}$ , and

cot60° = $\frac{1}{tan60}$ = $\frac{1}{\sqrt{3} }$

cos60° = $\frac{1}{2}$

cot60° cos60°

= $\frac{1}{\sqrt{3} }$ × $\frac{1}{2}$

= $\frac{1}{2\sqrt{3} }$ ← rationalise the denominator by multiplying by $\frac{\sqrt{3} }{\sqrt{3} }$

= $\frac{1}{2\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$

= $\frac{\sqrt{3} }{6}$
