Answer:
5. $4.50
6. 40 photo albums
7. s ≥ 4.25
8. r ≤-2; filled circle on -2 going to the left
Step-by-step explanation:
5.
(4 + x ) / 2 =4.25
<em>(multiply by 2) </em>
4 + x = 8.5
<em>(subtract 4) </em>
x= 4.5
6.
60 = 5 + (n * 1 3/8)
<em>(subtract 5) </em>
55 = n * 1 3/8
<em>(divide by 1 3/8) </em>
40 = n
7.
70 ≤ 36 + 8s
<em>(subtract 36) </em>
34 ≤ 8s
<em>(divide by 8) </em>
4.25 ≤ s
8.
9r + 3 ≤ -15
<em>(minus 3) </em>
9r ≤ -18
<em>(divide by 9) </em>
r ≤ -2

Step-by-step explanation:
The work form of this upside down parabola is

It's VERY important that you remember that the negative value there in front of the absolute value of a just means that the parabola is upside down. a itself will not be negative (and we know that because of the absolute value symbols there!). Filling in the x, y, h, and k values we were given allows us to solve for the |a|:
and
and
and
and
3 = -|a|
Again, the negative simply tells us the parabola is upside down, so the absolute value of a = 3, choice c.

Answer:
The three statements on the right hand side of the screen are the correct ones
Step-by-step explanation:
To take the average of the weight of the cat in the month of April is the following:
9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48
But then divide that by the number of samples:
48/5=9.6
The mean for April is 9.6
To take the average of the weight of the cat in the month of November is the following:
9.4 + 9.3 + 9.1 + 9.2 + 9 = 46
But then divide that by the number of samples:
46/5=9.2
Then, lastly, subtract the mean from November by the mean of April:
9.6-9.2=0.4
Answer:
891 pickles :)
Step-by-step explanation:
all you do is multiply 9 and 99 and you should get 891
