Megan Spins the sinner 8 times. In those 8 spins, the arrow never lands on 3. Based on this information, should Megan be concern
o-na [289]

The chance to land on the number three is only a ¼ or 0.25 chance. Knowing that we can also understand the law of large numbers. The law of large numbers states that as the number of spins gets very large, eventually the experimental probability will reach the theoretical probability. Eight spins of the spinner is not a large number, so the probabilities will be different. In this case resulting in zero times landing on three. Therefore, Megan should not be concerned that the spinner is unfair.

Help please! will give brainliest! and can please explain.
storchak [24]

Answer: 150

We know that cos Ф = sin (90 - Ф)

If Ф = 150, then:

cos 150 = sin (150 - 90)

cos 150 = sin 60

Using the equation they gave us:

cos 150 = sin ( \frac{150}{3} - 10)

cos 150 = sin 60

can someone answer my question????? pls this is already missing i’ll give brainlist and points don’t ignore
tensa zangetsu [6.8K]
Reminder: y = mx + b, to isolate y, you would need to subtract mx value, and what you do to one side, you do to all. If there’s a coefficient in front of your y value, you then divide the equation by that coefficient. Once y is isolated, m and b values are easier to find.

Answer:

1) y = -2x + 1 // m = -2, b = 1

2) y = 5/8x - 1 // m = 5/8, b = -1

3) y = 7/8x - 3/4 // m = 7/8, b = -3/4

4) y = 3/4x + 4 // m = 3/4, b = 4

X2 + 3x - 108 = 0<br> What is the answer?
worty [1.4K]

Answer:

The answer is x=9 and/or x = -12

Step-by-step explanation:

This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.

\frac{-3±\sqrt{9+4*1*-108} }{2}

which simplifies to -3 add or subtract the sqrt of 441 divided by two.
