1) BC intercept y at (2,1) (given)
2) The slope of AB ===> m= (-1 - 1)?(14 - 2) ===> m = - 1/6
2) the slope of BC that is perpendicular to AB is the inverse of (1/6) & change the sign, that is 6. To find the function y, apply the formula:
y-y1) = m(x-x1) ===> y-1 = 6(x-2) [the coordinate of B] ==> y= 12x - 11
3) if y= 13, replace y by 13 in the equation:
13 = 12x -11 ===>x = 2
It would be a right angle
Answer: 0.82 miles per gallon
Step-by-step explanation:
Given : Jenna has bought a new hybrid car. Each week for a period of seven weeks, she has noted the fuel efficiency (x) (in miles per gallon) of her car.
The results are :45 44 43 44 45 44 43
The formula to find the standard deviation is given by :-
First we find mean of the given data ,
Now,
Now, standard deviation of the above results will be :-
Hence, the standard deviation of these results = 0.82 miles per gallon
It would be 3 becuse 11/4 * 3 is 8.25 and is the highist to 9 so the answer would be 3
Okay so the probability of drawing a blue bean is
8 / 29 = .276
29 is the total number of jelly beans
When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.
But to find the probability of drawing a blue two times in a row, we must square the probability .
(.276) • (.276) = 0.076
Your answer is 7.6% !
