Answer:
-1
Step-by-step explanation:
Substitute a for 4 and b for -5.
Solve.
(-8,11)(4,7/2)
slope(m) = (7/2 - 11) / (4 - (-8) = (7/2 - 22/2) / (4 + 8) = (-15/2) / 12 = -15/2 * 1/12 = -15/24 = -5/8
y = mx + b
slope(m) = -5/8
use either of ur points...(-8,11)...x = -8 and y = 11
now we sub and find b, the y int
11 = -5/8(-8) + b
11 = 5 + b
11 - 5 = b
6 = b
so ur equation is : y = -5/8x + 6
Answer:
90
Step-by-step explanation:
all angels equal 180 so add the two you have then subtract 180 with the answer you got
Answer:
(I only did question 11 because the rest is just repetition)
Step-by-step explanation:
make the denominators the same by finding the LCM (lowest common multiple)
(I apologise if I do this incorrectly, the image is very blurry)
So what I did was make the denominator a number that both 2 and 3 can multiply to. (2x3=6 and 3x2=6)
Then whatever you do to the bottom you always do to the top.
- to go from 2 to 6, multiply by 3
- do that to the numerator
- to get from 3 to 6, multiply by 2
- do that to the numerator
= 17/6
Simplify to mixed fraction
P(A) = 1 - P(¬A) = 1 - 0.47 = 0.53
