Answer:
a. has one solution
b. infinite solution
Step-by-step explanation:
a.
2(x - 1) + 6 = 4x - 22
2x - 2 + 6 = 4x - 22
2x - 4x = 2 - 6 - 22
-2x = -26
x = 26/2
x = 13
b.
6(2x + 1) – 2 = 12x + 4
12x + 6 - 2 = 12x + 4
12x - 12x = 4 + 2 - 6
0 = 0
Answer:
the correct option is E. d is biased.
Step-by-step explanation:
As given,
The expected value of d hat is not equal to D.
We know that,
The unbiased-ness is the property that tells the expected value of d is equal to D
So, the correct option is E. d is biased.
Answer:
1122
Step-by-step explanation:
The translation is not changing the angles, because the all the points were moved 3 units to the right and two units down, so all the lines preserved their slopes.
Then if the angles A and B were 110 and 70 the images preserve the same angles.
Answer:
The number of hours that she work for the fast food is 11
The number of hours that she mowed is 5
Step-by-step explanation:
let x= hours spent mowing
y= hours spent at the food joint.
we can now form an equations from the figures given.
x+y=16...*
10.5x+4.25y=136.75...**
solving the two equations simultaneously using the substitution method or the eliminating method,
x=11 hours
y=5 hours
