Answer:
2
Step-by-step explanation:
The z-score is the number of standard deviations the value is above the mean. If that number is 2, then Z=2. If that number is -2, then Z=-2.
___
Both Z=2 and Z=-2 are values that are two standard deviations from the mean.
Answer:
A' and B'
Step-by-step explanation:
when u remove similar members from a union set, u will remain with unsimilar members in each set known as A only (A') and B only (B')
So let x be the cost for board
12,584 = 1704+x+x
12,584 = 1704+2x
12,584 - 1704 = 2x
10,880 = 2x
10,880/2 = x
5,440 = x
So the turion cost is 1704 + x
Which is 1,704+5,440 = 7144
Answer:
The x-intercept of the line will be at (32,0)
Step-by-step explanation:
The equation of a straight line passing through the two known points and is given by
Therefore, the equation of the straight line passing through the points (-12,14) and (-2,21) will be
⇒ 10(y - 14) = 7(x + 12)
⇒ 7x - 10y + 224 = 0 .......... (1)
Now, putting y = 0, we will get the x-intercept as 7x = - 224
⇒ x = - 32
Therefore, the x-intercept of the line will be at (- 32,0) (Answer)
