Answer:
x = 8
Step-by-step explanation:
Since both pools are similar, it follows that their side lengths are proportional.
Therefore:
BC = 4
FG = 3
AD = x
EH = 6
Plug in the values
Multiply both sides by 6
8 = x
x = 8
Yes you are correct. You take half of the x coefficient 18 to get 9, then you square 9 to get 81
x^2+18x+81 is a perfect square trinomial which factors to (x+9)^2
Answer:
sample proportion of defective items
Step-by-step explanation:
The p-chart is a type of chart in which the sample is taken periodically from the production process, so as to determine if the population proportion of defective items in the sample falls within the control limits on the chart.
For a P-chart, as the sample size gets larger it turns more into a normal distribution making it possible to approximate the distribution of the proportion defective.
Answer:
4+4-8 is a doubles fact that can help you find 4+3
Step-by-step explanation:
4+3=7
4+4=8
8-1=7
By using the doubles fact 4+4 we can deduct that 4+3 = 7
2nd term = 3 - 14 = -11
3rd tern = -11-14 = -25 answer
