Step-by-step explanation:
Y=5x-2
i’m assuming gradient means slope and you put the slope number next to x and the y-intercept at the end
Answer:
If you take into account all probabilities, and work on a strategy, rather than individual guesses, you can increase the probability.
Here are the possible outcomes:
BBB
BBR
BRB
BRR
RBB
RBR
RRB
RRR
If you use the strategy:
If a person sees a blue and a red, they pass;
If a person sees a blue and a blue, they guess red;
If a person sees a red and a red, they guess blue;
The probability comes out like this:
(B=blue, R=red, P=pass)
actual guess correct?
BBB RRR no
BBR PPR yes
BRB PRP yes
BRR BPP yes
RBB RPP yes
RBR PBP yes
RRB PPB yes
RRR BBB no
As you can see, this is a 6/8, or 75% chance of being correct.
Answer:
B. 97%
Step-by-step explanation:
20 students is -2 standard deviations away from the mean
35 is +3 standard deviations away from the mean
100 - 2.4 = 97.6
(2.4 is amount of data we are not using)
please refer to the standard deviation graph attached :)
