Y=10x+20
y=10×5y+20
y=50y+20
-20=50y-y
-20=49y
y=-20/49
Answer:
56
Step-by-step explanation: You have to substitute 6 for a because it says, "Which expression is equivalent to 7(a+2) when a=6"
7(a + 2)
7(6 + 2)
42 + 14
= 56
Population = all Texas 8th graders
Sample = Mrs. Jones's thirty 8th graders
Sampling method = convenience sampling
Yes, there was a sampling bias. Since the complete sample was from the same school and class, it does not represent the total population of Texas 8th graders very well.
Hoped this helped :D
The given data strongly suggests that the 5th child MIGHT be named 'May',
but really there's no way to know. We have no reason to assume that the lady
continued the same naming tradition that she established with her first four
children. For all we know, with four children in the house, she might have
named the 5th one "Enough Already!".
Question isn't well formatted, a picture if the question is attached below.
Answer:
1 / 4
Step-by-step explanation:
From the plot, each dot represent a gamer ; therefore, the total number of gamers will be counting all the dots ;
Total number of gamers = 24
Fraction of gamers that have 7 / 8 of the way to go ;
This means that they have 7/8 of the way left to proceed to next level ;
The fraction is : 1 - 7/8 = 1 /8
This means the number of of people whose progress are on 1/8 ; this is 6
Hence, fraction of gamers that have 7/8 of the way to go :
6 / 24 = 1 / 4
