Answer:
Option B:
Sammi made a mistake in Step 2 because he chose a title without knowing if the table represents the number of hours read per week.
Step-by-step explanation:
A dot plot type of a problem.
Sammi forgot to put the corresponding title for the dots such as whether those were the correspondents name or a universal label such as college students. This will make the graph have a mistake in some places. Sammi should include the label that corresponds or represents the dot.
There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.
-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.
-1r-4=-3
Now add 4 to both sides.
-1r-4=-3
+4=+4
-1r = 1
Now divide
R= -1
We shall use the equation A = i(1 + r/n)^nt
So we shall plug all of that in so it turns out like this:
A = 4000(1 + 0.04/4)^4 x 7
So then that can be simplified to A = (1.01)^28
and then to A = 4000(1.321)
so then A = 5285.16
<span>k+12/k=8
Multiply k to remove the k in one side
</span><span>(k+12/k=8) (k)
</span>Therefore,
k^2+12k-8k=0
Thus,
The equations he must solved now is k^2-8+12=0
