y=5/3x + 3 in ordered pairs
Answer:
(3,8) ; (-3,-2) ; (6,13)
Step-by-step explanation:
A linear equation in Slope Intercept Form is given to us and we need to write the ordered pairs for x and y . The given equation is ,
[tex]\rm\implies y =\dfrac{5}{3}x + 3 [/tex]
For finding the ordered pairs , substitute different values of x to get different values of y.
Put x = 3 :-
[tex]\rm\implies y =\dfrac{5}{3}\times 3 + 3 [/tex]
[tex]\rm\implies y = 5+ 3 [/tex]
[tex]\rm\implies y =8[/tex]
Put x = -3 :-
[tex]\rm\implies y =\dfrac{5}{3}\times -3 + 3 [/tex]
[tex]\rm\implies y = -5+ 3 [/tex]
[tex]\rm\implies y =-2[/tex]
Put x =6 :-
[tex]\rm\implies y =\dfrac{5}{3}\times 6 + 3 [/tex]
[tex]\rm\implies y = 10+ 3 [/tex]
[tex]\rm\implies y =13[/tex]
Therefore ,
[tex]\small\implies\boxed{\rm\blue{ Odered \ Pairs \ = (3,8) ; (-3,-2) ; (6,13) }}[/tex]

A certain drug carn be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 94% of patients taking the drug are healed within B weeks. In clinical trials, 228 of 240 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the a=0.05 level of significance. Click here to view the standard nomal distribution table (page 1). Cick here to view the standard nomal distribution table (page 2). Because rea (1-Po) =| satistied. (Pound to one decimal place as needed.) V 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis
According to the manufacturer's claim, we build an hypothesis test, find the test statistic and the p-value relative to this test statistic, reaching a conclusion that:
The p-value of the test is 0.2578 > 0.05, which means that there is not sufficient evidence to conclude that more than 94% of patients taking the drug are healed within B weeks.
The manufacturer of the drug claims that more than 94% of patients taking the drug are healed within 8 weeks.
At the null hypothesis, we test if the proportion is of at most 0.94, that is:
[tex]H_0: p \leq 0.94[/tex]
At the alternative hypothesis, we test if the proportion is of more than 0.94, so:
[tex]H_1: p > 0.94[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
0.94 is tested at the null hypothesis:
This means that [tex]\mu = 0.94, \sigma = \sqrt{0.94*0.06}[/tex]
In clinical trials, 228 of 240 patients suffering from acid reflux disease were healed after 8 weeks.
This means that [tex]n = 240, X = \frac{228}{240} = 0.95[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.95 - 0.94}{\frac{\sqrt{0.94*0.06}}{\sqrt{240}}}[/tex]
[tex]z = 0.65[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample proportion above 0.95, which is 1 subtracted by the p-value of Z = 0.65.
Looking at the z-table, Z = 0.65 has a p-value of 0.7422.
1 - 0.7422 = 0.2578.
The p-value of the test is 0.2578 > 0.05, which means that there is not sufficient evidence to conclude that more than 94% of patients taking the drug are healed within B weeks.

Area: Change in Dimensions
A rectangle FGHJ has a width of 3 inches and a length of 7 inches.
Step-by-step explanation:
this is not complicated at all. first and second graders can do a-c (come on, you know how to calculate the area of a rectangle) and with some imagination also d and e.
this is meant for you to actually do it so that you get a feeling for these things.
I will therefore leave the pure calculation to you.
and I will give you some help for the conceptual/ theoretical part.
the area of a rectangle is, of course, length × width (or height some on the view you have on an object).
let's just call them l and w.
so the regular area is
Ar = l×w
now one dimension (or example and for the width, but it does not matter, it is the same for the length) is doubled.
it simply means the new width is twice the old width.
so the area with a double width is
A2w = l×(2×w) = 2×(l×w)
so, that means also the area is doubled compared to the regular area.
now, both dimensions are doubled.
A2w2l = (2×l)×(2×w) = 4×(l×w)
so, the area grew 4 times a large as the regular area.
what is the rule here ?
let's triple the dimensions.
A3w3l = (3×l)×(3×w) = 9×(l×w)
as you can easily see : the new area grows with the square of the scaling factor, when we change both dimensions equally.
the reason is simple - as our little equations show, we have to multiply in the scaling factor of every dimension in play.
therefore, the new area grows with the product of the scaling factors of the involved dimensions. if both scaling factors are the same, then the area grows therefore by the square of the common factor.
and this principle applies to every shape, where the area is constructed out of 2 dimensions. any other additional multiplication factors don't matter for this, because this is all one big multiplication of several factors, and if you multiply one of these factors by an additional factor, the whole result changes by that factor.

∑x =11913 ∑y=34290 ∑x=3 ∑x²=1535 ∑xy=183040
Substituting the values
6a + 3b = 34290
3a + 1535b = 183040
solving the two by suitable elimination
6a + 3b = 34290
3(2a+b) = 3×11430
2a + b = 11430....(i)
and 3a + 1535b=183040....(ii)
a=173620/3067 = 5660.91
Putting a=5660.91 in (i)
2(5660.91) + b = 11430
b = 108.81
∴ a = 5660.91 and b = 108.81
Now substituting the values in the equation y=a+bx
y = 5660.91 + 108.81x
y = 5660.91 + 108.81(X-1985)
∴In 2020
y =5660.91 +108.81(2020 - 1985)
y = 9447.245

PLEASE HELPPO The top shelf of a bookcase holds 6 fiction and 4 nonfiction books. On the bottom shelf are 3 fiction and 5 nonfiction books.
Choosing which 2 books describes a pair of dependent events?
Answer:
Two consecutive events are dependent if the outcome of the second event depends on the outcome of the first event.
Now, suppose that all the books have the same probability of being drawn, let's look at a single shelf.
we take a book from the first shelf, let's ignore the type of book for now.
Now, if we want to get a second book from that shelf, the probability of getting a fiction book is equal to the quotient between the number of fiction books on the shelf and the total number of shelf.
Now we can see that, if the first book drawn was a fiction book, now there are 5 fiction books and 9 books in total, so:
p = 5/9
if the first book was a non-fiction book, now there are 6 fiction books in the shelf and 9 books in total, so the probability in this case is:
q = 6/9
So you can see that the outcome of the second draw depends on the outcome of the first one (only in the case where we take two books from the same shelf)
Then the pair of dependent events is:
A: because in both cases we choose a book from the same shelf
D: because in both cases we choose a book from the top shelf.

Answer:
It is indeed 63
Step-by-step explanation:
The easy way to go about this is to recognize that if the triangles are similar, the ratio between the similar sides will be the same.
Notice:
4/5 = 36/45
So:
4/7 should = 36/x
If:
4/7 = 36/x
4x/7 = 36
4x = 36*7
x=36*7/4
x=63
Suppose a + bi and c + di are complex numbers with b not equaling 0.
(a) Calculate (a + bi) + (c + di) and (a + bi)(c + di).
(b) Show that if both the sum and product are real numbers, then either the complex numbers are real numbers or conjugates.
9514 1404 393
Answer:
(a) sum: (a+c) +(b+d)i
product: (ac -bd) +(bc +ad)i
(b) (b+d)=0 and (bc+ad)=0 ⇒ a=c, d=-b or b=d=0
Step-by-step explanation:
(a) Combining like terms the sum is ...
(a +bi) +(c +di) = (a+c) +(b+d)i . . . . sum
And the product is ...
(a+bi)(c+di) = ac +(ad+bc)i +bd·i²
Since i = √-1, i² = -1 and the product can be written as ...
(a+bi)(c+di) = (ac-bd) +(ad+bc)i . . . . product
__
(b) If both the sum and product are real numbers, then we have ...
b +d = 0
ad +bc = 0
The first equation tells us d = -b. Substituting that into the second equation, we get ...
a(-b) +b(c) = 0
b(c -a) = 0
The zero product rule tells us this will be true if and only if b = 0 or c = a.
if b = 0, then d = 0 and both numbers are real.
if c = a, then c+di = a-bi and the numbers are conjugates.
Hence, if both the sum and product are real, both are real numbers or they are conjugates.

Surface roughness of pipe. Refer to the Anti-corrosion Methods and Materials (Vol. 50, 2003) study of the sur- face roughness of coated interior pipe used in oil fields, Exercise 7.26 (p. 311). The data (in micrometers) for 20 sampled pipe sections are reproduced in the table on p. 391.
a. Give the null and alternative hypotheses for testing whether the mean surface roughness of coated interior pipe, H, differs from 2 micrometers.
b. The results of the test, part a, are shown in the MINITAB printout at the bottom of the page. Locate the test statistic and p-value on the printout.
The minitab report isn't given.
Answer:
H0 : μ = 2 um
H1 : μ ≠ 2 um
Step-by-step explanation:
The mean surface roughness of coated interior pipe is given as 2um.
This refers to the population mean, μ = 2 um
Therefore, the null hypothesis which usually aligns with the population mean value will be stated as :
H0 : μ = 2 um
The alternative hypothesis is used to test the claim that the mean surface roughness is different from 2 ; hence no direction is given, this is thus a 2 - tailed test
H1 : μ ≠ 2 um
