Answer:
10.7
Step-by-step explanation:
Answer:
2.5th percentile and the 97.5th percentile.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

So we obtain the 0.025*100 = 2.5th percentile and the (1-0.025)*100 = 97.5th percentile.
So the answer is:
2.5th percentile and the 97.5th percentile.
1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or
8:32.
2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x =
52 [tex] \frac{miles}{hour} [tex]

<h2>22</h2>
In this problem, we need to use <u>multiplication</u> and <u>subtraction</u> method to solve it.
_________________________________
x(y) means to <u>multiply</u> x with y
_________________________________
Note that {a = 7} and {b = 6}
First, we need to multiply 4 with {a = 7}, we get:
4(7) = <em>28</em>
<em />
Then, we need to subtract {b = 6} from <em>28</em>, we get:
<em>28</em> – 6 = 22
Finally, this simplifies as:
4(7) – 6 = 22
