First draw a straight line and plot the four points A,B,C,D on that line. It doesn't matter where you plot the points as long as they are in order and none overlap.
We're given AD = x+203. We also know that BD = x+127. Since AB + BD = AD (segment addition postulate) we can determine the length of AB
AB + BD = AD
AB + BD-BD = AD-BD Subtract BD from both sides.
AB = AD-BD
AB = (x+203)-(x+127)
AB = x+203-x-127
AB = 76
The length of BC is also 76 (given). So,
AB+BC = 76+76 = 152
this is equal to the length of AC because AB+BC = AC
So, AC = 152 units
Final Answer: 152 units

A production process produces electronic component parts. It is presumed that the probability of a defective part is 0.01. During a test of this presumption, 500 parts are sampled randomly and 15 defectives are observed. (a) What is your response to the presumption that the process is 1% defective
Testing the hypothesis, we have that since the p-value of the test is 0 < 1, our response is that the presumption underestimates the proportion of defective parts.
At the null hypothesis, we test if the proportion of defectives is of at most 1%, that is:
[tex]H_0: p \leq 0.01[/tex]
At the alternative hypothesis, we test if the proportion of defectives is of more than 1%, that is:
[tex]H_1: p > 0.01[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
From the sample, we have that:
[tex]n = 500, \overline{p} = \frac{15}{500} = 0.03[/tex]
Thus, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.03 - 0.01}{\sqrt{\frac{0.01(0.99)}{500}}}[/tex]
[tex]z = 4.49[/tex]
The p-value of the test is the probability of finding a sample proportion above 3%, which is 1 subtracted by the p-value of z = 4.49.
z = 4.49 has a p-value of 1.
1 - 1 = 0.
The p-value of the test is 0 < 1, which means that our response is that the presumption underestimates the proportion of defective parts.

27/125 in simplest form
[tex] \frac{27}{125} [/tex]
It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Answer:
27 /125
is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 27 and 125 is 1
Divide both the numerator and denominator by the GCD
27 ÷ 1 /125 ÷ 1
Reduced fraction:
27 /125
Therefore, 27/125 simplified to lowest terms is 27/125.

Step-by-step explanation:
quadratic graphs
y=x squared - 4x
This is one way of doing it.
We want to get the function into vertex form.
y = x2 - 4x + 2 Subtract 2 from both sides.
y - 2 = x2 - 4x Add (-4/2)2 , or 4, to both sides.
y - 2 + 4 = x2 - 4x + 4 Now that the right hand side is a perfect square trinomial, factor it.
y + 2 = (x - 2)(x - 2)
y + 2 = (x - 2)2 Subtract 2 from both sides.
y = (x - 2)2 - 2
When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)

Answer:
1) 2 and 4
2) 3 and 4
3) 7 and 8
4) 9 and 10
5) 21 and 22
Step-by-step explanation:
#1
Since √(8) = √(2×4) = 2√2
then the √(8) lies between 2 & 3
#2
Since √(9) = 3 & √(16)= 4
then √(14) lies between 3 & 4
#3
√(60) = √(4×15) = 2√(15)
since √16 = 4 and 4 × 2 = 8
then 2√(15) < 8
∴ the √16 lies between 7 & 8
#4
√99 = √(9×11) = 3√11
√11 lies between √9 & √16 but closer to √9
& 3 × √16 = 12
the 3√11 = √99 likely lies between 9 & 10
#5
√444 = √(4×111)= 2√111
since √100 = 10 & √121 = 11
& 2×10= 20 & 2×11= 22
then 2√111 is likely between 21 & 22
