The answer is to isolte the unknown on one side by itself so
I hope you know how number lines because It is hard to do on branly so
1.
h-16 <u><</u>-24
add 16 to both sides
h<u><</u>8
graph
2. y+6 <u>></u>-13
subtract 6
y<u>></u>-19
graph
3. -3<n-8
add 8 to both sides
5<n
graph
4. 3<u><</u>m+1.4
subtract 1.4 from both sides
1.6<u><</u>m
graph
5. x+0.7>-0.3
subtract 0.7 from both sides
x>-1
graph
6. w-8<u>></u>5.6
add 8 to both sides
w<u>></u>13.6
graph
The answer is 6.33 units.
It'd be easier to do #18 if y ou were to break it up:
14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2
14(1+14)
= ---------------- = 7(15) = 105
2
The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.
The final sum is 210 + 14 = 224 (answer)
Answer:
A Type I error would occur if there was no evidence of an improvement on the national exam but there really was improvement.
Step-by-step explanation:
A type 1 error simply occurs when we incorrectly reject a true null hypothesis. In the scenario above, An experiment was conducted in other it know if there is sufficient evidence to support a claim that a new teaching method developed improves students score. If this claim is actually true in the real sense. However, after conducting a statistical test, we conuded that there was no sufficient evidence to support her claim of improvement using the new method, hence, the claim was rejected. By rejecting the claim, a true null has been rejected. Hence, a type 1 error has been committed.
