5/9-3/8+(-1/4)+1 4/9+1 5/8=3
Answer: yes
Step-by-step explanation:
You’re multiplying every x value by 4 to get the y values
(Someone got mad at me for not including a better explanation so here you go:
x = 3 y = 12..... 3(k) = 12 (divide both sides by three)
k = 4
x = 5 y = 29..... 5(k) = 20 (divide both sides by five)
k = 4
So on and so forth for the rest of the table
Answer:
1. A: 0.25; B: 0.03; C: 1.41; D: -0.28
2. A: 0.39; B: 0.06; C: 40.30; D: 21.81
Step-by-step explanation:
For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.
Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.
For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
Answer:
C) x=2 and x= -14
Step-by-step explanation:
|x + 6| = 8
means
x + 6 = 8 or x + 6 = -8
x + 6 = 8
x = 2
x + 6 = -8
x = -14
Answer:
Step-by-step explanation:
how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
