(70 -100)/15 = -2 . . . . the z-score of a score of 70
p(z < -2) ≈ 2.3%
A score of 70 would place you in approximately the 2nd percentile.
Y = -2/3x + 5....the slope here is -2/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, we flip the slope and change the sign. So our perpendicular line will have a slope of 3/2 (see how I flipped -2/3 making it -3/2....and then changed the sign, making it 3/2)
y = mx + b
slope(m) = 3/2
(8,1)....x = 8 and y = 1
now we sub and find b, the y int
1 = 3/2(8) + b
1 = 12 + b
1 - 12 = b
-11 = b
so ur perpendicular equation is : y = 3/2x - 11 <==
Answer:
Your missing a number and your answer is 12
Step-by-step explanation:
24 bottles in total.....6 orange and 4 apple
probability of first picking an orange is 6/24 reduces to 1/4
probability of second picking an apple is 4/23
probability of both is 1/4 * 4/23 = 1/23
Answer:
in step 4
Step-by-step explanation:
we have
so step 1 is correct
step 2
so step 2 is correct
step 3
so step 3 is correct
step 4
so step 4 is incorrect
