Answer:
A
Step-by-step
because the variable is squared you have to find the square to simplify it.
Answer:
y=-9x+193
Step-by-step explanation:
Its decreasing by 9, and 175+(9x2) is 193
When you square +6 or -6 you get 36. That's less than 40.
When you square +7 or -7, you get 49. That's more than 40.
So one of the square roots of 40 is between <em>+6 and +7</em>, and
the other square root of 40 is between <em>-7 and -6 </em>.
Answer:
There is a 90.32% probability that the cake was baked by Doug.
Step-by-step explanation:
We have these following probabilities:
A 70% probability that Doug bakes the cake.
A 30% probability that Jeremy bakes the cake.
A 40% probability that a cake baked by Doug gets a thumbs up.
A 10% that a cake baked by Jeremy gets a thumbs up.
One cake was selected at random on 10/01/2014 and got a "thumbs up".
1. Find the probability that the cake was baked by Doug.
The probability that a baked cake gets a thumbs up is:
Of those, 0.7*0.4 = 0.28 are baked by Doug.
So the probability is:
There is a 90.32% probability that the cake was baked by Doug.
Y = 3/5x + 3
The number before x is the slope, and the last number is the number when x = 0 (aka x,y in coordinates)
