The missing length is 51.5, I hope this helps :)
2x + 4 > 8
Step 1: Subtract 4 from both sides.
2x + 4 − 4 > 8 − 4
2x > 4
Step 2: Divide both sides by 2.
2x/2 > 4/2
x > 2
2x − 3 < 5
Step 1: Add 3 to both sides.
2x − 3 + 3 < 5 + 3
2x < 8
Step 2: Divide both sides by 2.
2x/2 < 8/2
x < 4
<u>Answer:</u>
3 and 60
<u>Step-by-step explanation:</u>
For the given proportions, 
, 3 and 60 are the extremes while 12 and 15 are the means.
To understand this, we can take a look at an example.
Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as
:
Here, a and d are the extreme ends and b and c are the means.
Answer:
60% decrease.
Step-by-step explanation:
Let's use a ratio:
touchdowns : decreased
15 : 6
5 : 2
100 : 40
The percent decrease is 60%
Answer:
a. No the null hypothesis cannot be rejected at 1% level of significance as the calculated value of z= 2.222 which lies with in 2.333
b. Yes for the Type 1 Error of 2.5% we say the toaster oven consumes more than 250 W of power because the calculated value 2.22 lies outside the region for 1.96
c. The cut-off at 2.5% level of significance is 258.82 W.
d. 0.85 is the area for Type 2 error.
e. The cut-off at 1% level of significance is 260.485W.
f. 0.154 is the area for Type 2 Error
g. The Type 2 Error is increased when Type 1 Error is decreased.
h. The Type 1 Error is decreased when Type 2 Error is increased .
