Answer:
so yea what was the answer again
Step-by-step explanation:
First get slope
(4,-1) and (-2,3)
slope is
diff in y 4
---------- = ---- = -2/3
diff in x -6
use a point (-2, 3) and y - y1=M(x - x1)
y - 3= -2/3(x + 2)
y - 3= -2/3x - 4/3
+ 3 +3
y = -2/3x - 4/3 + 9/3 (3 is 9/3)
y = -2/3x + 5/3
Answer:
<u>The correct answer is C. 20.33%</u>
Step-by-step explanation:
1. Let's review all the information given to us to answer the question correctly.
Mean of time of adults walking a mile = 22 minutes
Standard deviation = 6 minutes
Normal distribution for the walking times
2. What percentage of adults take longer than 27 minutes to walk a mile?
27 minutes = Mean + 5 minutes
27 minutes = Mean + 0.83 * Standard deviation
Using the z table for z = 0.83, we have that:
P (z) = 0.7967
Therefore the probability of adults that take longer than 27 minutes walking a mile is:
1 - 0.7967 = 0.2033
<u>The correct answer is C. 20.33%</u>
Answer:
(gxf)(1) = - 12
Step-by-step explanation:
Let f(x) = -4x + 7 and g(x) = 2x - 6.
(gxf)(1) = g(1)xf(1)
but : f(1) = -4(1)+7 =7-4 = 3 and g(1)=2(1)-6 =2-6 = -4
so : (gxf)(1) = g(1)xf(1) = (-4)(3)=-12
