The mistake Jadyn made in the long division is
- Mistake in subtraction
- the first quotient
<h3>What is long division ?</h3>
Long division refers to a way of dividing large numbers
performing the long division correctly gives
divisor dividend quotient multiplication subtraction new dividend
8 335 40 8 * 40 = 320 335 - 320 15
8 15 1 8 * 1 = 8 15 - 8 7
8 70 0.8 8 * 8 = 64 70 - 64 6
8 60 0.07 8 * 7 = 56 60 - 56 4
8 40 0.005 8 * 5 = 40 40 - 40 0
The quotient is then added as
40 + 1 + 0.8 + 0.07 + 0.005 = 41.875

Graph the absolute value by using the vertex and a few selected points
Point One: X= -1, Y= -8
Point Two: X= 0, Y= -2
Point Three: X= 1, Y= 4
Point Four: X= 2, Y= -2
Point Five: X= 3, Y= -8
The graph should look something like a mountain or an upside down V
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
