Answer:
Step-by-step explanation:
Using the area model and standard algorithm, we have:
332 (tenths)
<u> × 21 </u>
332
<u> 664 </u>
<u> 6972 </u> tenths = 697.2
<u />
30 + 3 tenths
1 300 32 332
20 600 64 664
33.2 × 21 =<u> 30 </u> × <u> 1 </u> = <u> 30 </u>
AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1
120 is your answer! (I looked it up!)
Answer:
The correct answer is "0.3410, 0.4990".
Step-by-step explanation:
Given values are:



At 95% confidence interval,
C = 95%
z = 1.96
As we know,
⇒ 
By substituting the values, we get



hence,
The confidence interval will be:
=
