Answer:
Step-by-step explanation:
A blue marble ⇒ 6 points.
- x blue marbles ⇒ 6x points
A green marble ⇒ 9 points.
- y green marbles ⇒ 9y points
For each red marble ⇒ - 12 points.
- z red marbles ⇒ -12z points
<u>Total number of points:</u>
Answer:
16x4+12x3−10x2+13x−3
Step-by-step explanation:
Let's simplify step-by-step.
16x4+12x3−10x2+8x+204x−3
=16x4+12x3+−10x2+8x+5x+−3
Combine Like Terms:
=16x4+12x3+−10x2+8x+5x+−3
=(16x4)+(12x3)+(−10x2)+(8x+5x)+(−3)
=16x4+12x3+−10x2+13x+−3
Answer:
(2,-1)
Step-by-step explanation:
Reflecting over the x-axis means the y values become negative
Answer:
Malcolm is showing evidence of gambler's fallacy.
This is the tendency to think previous results can affect future performance of an event that is fundamentally random.
Step-by-step explanation:
Since each round of the roulette-style game is independent of each other. The probability that 8 will come up at any time remains the same, equal to the probability of each number from 1 to 10 coming up. That it has not come up in the last 15 minutes does not increase or decrease the probability that it would come up afterwards.
In your question where ask to find the Standard Normal Distribution of the following:
give probabilities for 0<Z<infinity.
For these ranges, you can read directly, for example,
P(Z<1.96)=0.975.
So for #1, you read directly on the line 1.3 and column 0.03.
For #2, we note that the distribution is symmetrical about Z=0, so
P(Z<-2.33) is the same as P(Z>2.33)
which again is the same as
1-P(Z<2.33) because we know that the area under a probability distribution function adds up to 1.
For the remaining questions, work is similar to #2.
