Step-by-step explanation:
3 is a whole number, 5 is in the tenths place, 8 is in the hundreths place, and 7 is in the thousandths place. Eventhough 8 is in the tenths place, we have to apply a certain rule to get the exact answer. if the number in the next place (the thousandths place so 7) is greater than 5, add 1 to the tenths place number, but if the number is less than 5, leave it as it is. The 8 will round to 9 because 7 is greater than 5.
The accompanying data resulted from an experiment in which weld diameter x and shear strength y (in pounds) were determined for five different spot welds on steel. A scatterplot shows a pronounced linear pattern. The least-squares line is y hat = -959.00 + 8.60x. Because 1 lb = 0.4536 kg, strength observations can be re-expressed in kilograms through multiplication by this conversion factor: new y = 0.4536(old y). What is the equation of the least-squares line when y is expressed in kilograms? (Give the answer to two decimal places.)
Answer:
y hat = 2114.20 + 18.96x
Step-by-step explanation:
Given the least square regression model equation:
y hat = -959.00 + 8.60x
weld diameter x ; shear strength y (in pounds)
1 lb = 0.4536 kg
To express shear strength y in kilogram:
y is multiplied by 0.4536
(y hat × 0.4536) = -959.00 + 8.60x
Divide both sides by 0.4536
(y hat × 0.4536) / 0.4536= (-959.00 + 8.60x) / 0.4536
y hat = 2114.1975 + 18.959435x
y hat = 2114.20 + 18.96x
The equation of the least-squares line when y is expressed in kilograms is y = 2114.20 + 18.96x.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more two variables.
The accompanying data resulted from an experiment in which weld diameter x and shear strength y (in pounds) were determined for five different spot welds on steel. A scatterplot shows a pronounced linear pattern.
The least-squares line is [tex]\rm y = -959.00 + 8.60x[/tex]. Because [tex]\rm 1\ lb = 0.4536 \ kg[/tex] the strength observations can be re-expressed in kilograms through multiplication by this conversion factor:
New [tex]\rm y = 0.4536 (old \ y)[/tex].
y is multiplied by 0.4536, then we have
[tex]\rm y \times 0.4536 = -959.00 + 8.60x[/tex]
Then divide both sides by 0.4536, then we have
[tex]\rm y = \dfrac{-959.00 + 8.60x}{0.4536}\\\\\\\rm y =2114.20+ 18.96 x[/tex]

Answer:
Hello your question is incomplete below is the missing part of the question
Metropolitan Research, Inc., a consumer research organization, conducts surveys designed to evaluate a wide variety of products and services available to consumers. In one particular study, Metropolitan looked at consumer satisfaction with the performance of automobiles produced by a major Detroit manufacturer. A questionnaire sent to owners of one of the manufacturer's full-sized cars reviewed several complaints about early transmission problems. To learn more about the transmission failures, Metropolitan used a sample of actual transmission repairs provided by a transmission repair firm in the Detroit area. The following data show the actual number of miles driven for 50 vehicles at the time of transmission failure:

4.) How many repair records should be sampled if the research firm wants the population mean number of miles driven until transmission failure to be estimated with a margin of error of 5000 miles? Use 95% confidence.
answer : 1) Min value = 25070 1st quarter = 60420,Median = 72700,Mean = 73340,3rd quarter = 86580,Max value = 138100
2) ( 66438.73, 80241.87 )
3) The statistical results shows that some owners of the automobiles experienced early transmission failures
4) 95
Step-by-step explanation:
1) The transmission failure ( using descriptive statistics )
Min = 25070
1st quarter = 60420
Median = 72700
Mean = 73340
3rd quarter = 86580
Max = 138100
2) managerial interpretation of interval estimate
given 95% confidence interval
a = 0.05
z(0.025) = 1.96
Hence the 95% confidence interval for the mean number of miles driven until transmission failure
= xbar +/- Z*s/vn
⇒ 73340.3 +/- 1.96*24898.72 * [tex]\sqrt{50}[/tex]
= ( 66438.73, 80241.87 )
3) The findings shows that some owners of the automobiles experienced early transmission failures
4 ) number of repair records
n = ( Z * S/E) ^2 ------- 1
Where : Z = 1.96, S = 24898.72, E = 5000
= 1.96 * 24898.72 / 5000 ) ^2
= 95

y = -1 + 4
y = 3
So , the value of y = 3
b)
Let the equation be y = - ( - x )²
For all the values of x , the value of y will be negative
So , the value of y ≠ 3
c)
Let the equation be y = x⁵
when x = 3^ (1/5)
y = ( 3^ (1/5) )⁵
y = 3
So , the value of y = 3

A recent college graduate is planning to take the first three actuarial examinations in the coming summer. She will take the first actuarial exam in June. If she passes that exam, then she will take the second exam in July, and if she also passes that one, then she will take the third exam in September. If she fails an exam, then she is not allowed to take any others. The probability that she passes the first exam is .9. If she passes the first exam, then the conditional probability that she passes the second one is .8, and if she passes both the first and the second exams, then the conditional probability that she passes the third exam is .7.
(a) What is the probability that she passes all three exams?
(b) Given that she did not pass all three exams, what is the conditional probability that she failed the second exam?
Answer:
(a) 0.7
(b) [tex]\frac 13[/tex]
Step-by-step explanation:
Let [tex]E_1, E_2,[/tex] and [tex]E_3[/tex] be the events of passing the 1st, 2nd, and 3rd exam individually.
Given that [tex]P(E_1)=0.9\;\cdots(i)[/tex]
where [tex]P(E_1)[/tex] denotes the probability of passing the 1st exam.
Condition for passing the second exam is, at first, the candidate must have to pass the 1st exam.
So, [tex]P\left(\frac{E_2}{E_1}\right)=0.8\;\cdots(ii)[/tex]
where [tex]P(E_2/E_1)[/tex] denotes the probability of passing the 2nd exam when she already passed the 1st exam (given, 0.8).
Similarly, as the conditional probability of passing the 3rd exam is 0.7, and the condition for this is, at first, she must have to pass the 1st and 2nd exam. i.e,
[tex]P\left(\frac{E_2}{P(E_2/E_1)}\right)=0.7\;\cdots(iii)[/tex]
(a) For passing all the exams, the condition is, at first, she has to pass the 1st and 2nd exam, then she has to pass the 3rd exam too. The probability for this conditional has been given as 0.7.
So, the probability that she passes all three exams is 0.7.
(b) Given that she didn't pass all three exams that means she either failed in 1st exam or she passed the 1st and failed in 2nd exam or she passed both 1st and 2nd but failed in the 3rd exam.
Let F be the event that she didn't pass all three exams. So,
[tex]P(F)=(1-P(E_1))+\left(1-\frac{P(E_2)}{P(E_1)}\right)+\left(1-\frac{P(E_2)}{P(E_2/E_1)}}\right)[/tex]
[tex]\Rightarrow P(F)=(1-0.9)+(1-0.8)+(1-0.7)=0.6[/tex]
Lef [tex]F_2[/tex] be the event that she failed the 2nd exam, so
[tex]P(F_2)=1-\frac{P(E_2)}{P(E_1)}[/tex]
[tex]\Rightarrow P(F_2)=1-0.8=0.2[/tex]
So, the conditional probability that she failed the 2nd exam is
[tex]P\left(\frac{F_2}{F}\right)=\frac{P(F_2)}{P(F)}[/tex]
[tex]\Rightarrow P\left(\frc{F_2}{F}\right)=\frac{0.2}{0.6}=\frac{1}{3}=0.33[/tex]

Lines b and a are intersected by line f. At the intersection of lines f and b, the bottom left angle is angle 4 and the bottom right angle is angle 3. At the intersection of lines f and a, the uppercase right angle is angle 1 and the bottom left angle is angle 2. Which set of equations is enough information to prove that lines a and b are parallel lines cut by transversal f? m∠4 = 110° and m∠3 = 70° m∠1 = 110° and m∠2 = 110° m∠1 = 110° and m∠3 = 70° m∠2 = 110° and m∠3 = 110°
Answer:
m∠1 = 110° and m∠3 = 70°
Step-by-step explanation:
The angles at the intersection of a transversal and parallel lines are supplementary angles.
The true statement is: [tex]\mathbf{\angle 1 = 110^o}[/tex] and [tex]\mathbf{\angle 3= 70}[/tex]
From the complete question, we have:
[tex]\mathbf{\angle 1 = 110^o}[/tex]Angle 1 is supplementary to angle 3This means that:
[tex]\mathbf{\angle 1 + \angle 3= 180^o}[/tex]
Substitute [tex]\mathbf{\angle 1 = 110^o}[/tex]
[tex]\mathbf{110 + \angle 3= 180^o}[/tex]
Subtract 110 from both sides
[tex]\mathbf{\angle 3= 180 - 110}[/tex]
[tex]\mathbf{\angle 3= 70}[/tex]
Hence, the true statement is: [tex]\mathbf{\angle 1 = 110^o}[/tex] and [tex]\mathbf{\angle 3= 70}[/tex]

Let p, q, and r be the following propositions:
The water is warm.
People are swimming.
The waves are not big.
Express each of the following sentences using p, q, r, and logical connectives: and, or, not.
A) The water is warm and people are swimming.
B) If people are not swimming, then the water is not warm or the waves are big.
C) If the waves are big and the water is warm, then the people are not swimming.
Answer and Step-by-step explanation:
P= the water is warm.
q = people are swimming.
r = the waves are not big.
Logical connectives are:
Not p = ¬p
P or q = p ∨ q
P and q = p ∧ q
If p, then q = p → q
P if and only if
q = p ↔ q
By using p, q, r and logic connectives and or not, we have:
1-water is warm and people are swimming.
= p ∧ q
2- If people are not swimming then water is not warm or waves are big.
= ¬q → ¬p v ¬r
3- if waves are big, water is warm then people are not swimming
