Sean has scored a score of 65% on his spelling test
If you use the distributive property and multiply -22 by x and 2 you will come out with y+5= -22x-44. Then subtract 5 and it would cancel out and you subtract it from the -44. -44-5 is equal to -49. So your equation would be y= -22x-49. This means that your slope would be -22.
Answer: 23.7 lb
Step-by-step explanation:
Mean m = 15 lb
Standard deviation d = 3.3 lb
To determine the surcharge weight, we need to know the highest weight of 99% of the parcels.
P(z<x) = 0.99 = ¢(Z)
Z = 2.33
Since Z = (x - m)/d
x = dZ + m
x = 3.3*2.33 + 15
x = 22.689 lb approximately
x = 22.7 lb
Therefore, the highest weight for 99% if the parcels is 22.7 lb.
That is, the surcharge weight = 22.7 + 1 = 23.7 lb
Answer:
-0.55
Step-by-step explanation:
-0.55
Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x
