help me plz The formula K=59(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.
a. Solve the formula for F.
F=
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
[tex]k = 59(f - 32) + 273.15[/tex]
Subtract the sides of the equation minus -273.15
[tex]k - 273.15 = 59(f - 32)[/tex]
Divided the sides of the equation by 59
[tex] \frac{k - 273.15}{59} = \frac{59}{59} (f - 32) \\ [/tex]
[tex] \frac{k - 273.15}{59} = f - 32 \\ [/tex]
Subtract the sides of the equation plus 32
[tex] \frac{k - 273.15}{59} + 32 = f \\ [/tex]
And we're done.
Thanks for watching buddy good luck.

A recent study examined hearing loss data for 1628 U.S. teenagers. In this sample, 337 were found to have some level of hearing loss. News of this study spread quickly, with many news articles blaming the prevalence of hearing loss on the higher use of ear buds by teens. At MSNBC (8/17/2010), Carla Johnson summarized the study with the headline: "1 in 5 U.S. teens has hearing loss, study says." To investigate whether this is an appropriate or a misleading headline, you will conduct a test of significance with the following hypotheses:
Null: π = 0.20 Alternative: π ≠ 0.20
A) Describe what the symbol π stands for in this context.
B) Use the Theory-Based Inference applet to determine a p-value.
C) Based on your p-value is there strong evidence that the proportion of all U.S. teens with some hearing loss is different than 1 in 5 (or 20%)?
D) Using the applet, find a 95% confidence interval for the proportion of U.S. teens that have some hearing loss.
E) What is the margin of error for you confidence interval from part (d) of this question?
F) Based on your confidence interval, is 0.20 a plausible value for the proportion of the population that has some hearing loss? Explain why or why not.
G) Based on your p-value, is 0.20 a plausible value for the proportion of the population that has some hearing loss? Explain why or why not.

I’m confused !!!!!!!!!!
Answer:
Ok, so what you have to do is find the range of the number the way you find the range is by writing down the relation. (the relation is the set of the ordered pairs with x and y coordinates). Then you have to list the y-coordinates of the relation. The way to find the range of the relation, you simply have to write down all of the y-coordinates of each ordered pair. Also, make sure to remove any duplicate coordinates so that you only have one of each y-coordinate.
The way you find the ordered pair is by moving a certain amount of steps to the left or right on the x-axis and a certain amount of steps upwards or downwards on the y-axis.
Explanation:
I'm sorry for not giving you the actual range and the ordered pairs for each number but I have to have a graph so I can see and verify an actual answer. I hope that my explanations help you figure out what the answer is! Have a nice day! :)
Universal Claims Processors processes insurance claims for large national insurance companies. Most claim processing is done by a large pool of computer operators, some of whom are permanent and some of whom are temporary. A permanent operator can process 16 claims per day, whereas a temporary operator can process 12 per day, and on average the company processes at least 450 claims each day. The company has 40 computer workstations. A permanent operator generates about 0.5 claim with errors each day, whereas a temporary operator averages about 1.4 defective claims per day. The company wants to limit claims with errors to 25 per day. A permanent operator is paid $64 per day, and a temporary operator is paid $42 per day. The company wants to determine the number of permanent and temporary operators to hire in order to minimize costs.

The sum and product of two linear functions are shown.
Which statements can be used to describe the original functions f(x) and g(x)? Select two options.
A. When added, the sum of the y-intercepts must be 1.
B. When multiplied, the product of the y-intercepts must be –15.
C. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change.
D. f(x) could have a rate of change equal to 1 and g(x) could have a rate of change of 2.
E. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –6.
Answer:
A and DStep-by-step explanation:
Let the functions be
f(x)= ax + bg(x) = cx + dTheir sum
j(x) = (a+c)x + b+dTheir product
k(x)= (ax + b)(cx + d)The answer optionsA. When added, the sum of the y-intercepts must be 1.
Correct. We see point (0,1) of j(x) on the graph. b+d = 1B. When multiplied, the product of the y-intercepts must be –15.
Incorrect. -15 is the vertex of k(x). The vertex of ax^2 + bx + c is -b/2a. So it has no relation to constants of the functions f(x) and g(x)C. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change.
Incorrect. It refers to the value of ac. If one of a or c has opposite sign it makes k(x) to open down but it is not as per graph.D. f(x) could have a rate of change equal to 1 and g(x) could have a rate of change of 2.
Correct. As per above statement, both linear equations could be positive as their sum and product is positive from the graphs of j(x) and k(x)E. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –6.
Incorrect. It should result in decreasing function of j(x) with slope of -4 but it is increasing as per graph.Triangle ABC is transformed to create triangle MNO and triangle PQR as described below.

Answer:
Step-by-step explanation:
The equation of the line is y - 1 = ( 5/6)(x - 1 ).
What is the equation of a line passing through two points?Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

A high school race track is composed of a rectangle and two semicircles.
a. If the length "l" of the rectangle is twice as long as the diameter of the semicircles, write a formula for "p," the distance around the track, in terms of the radius "r" of the semicircles.
b. Rewrite the formula from a so the radius of the semicircles is given in terms of the distance around the track. Show your work.
Answer:
a. [tex] p = 2\pi r + 8r [/tex]
b. [tex] r = \frac{p}{2\pi + 8} [/tex]
Step-by-step explanation:
a. Radius of semicircle (r) = r
Diameter of semicircle (d) = 2r
Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r
Distance around the track (p) = circumference of circle + 2(l)
Note: the two semicircles of the track = 1 full circle
Circumference of full circle = πd = π*2r = 2πr
Distance around the track:
p = 2πr + 2(4r)
p = 2πr + 8r
b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.
[tex] p = 2\pi r + 8r [/tex]
Factor out r
[tex] p = r(2\pi + 8) [/tex]
Divide both sides by (2π + 8)
[tex] \frac{p}{2\pi + 8} = \frac{r(2\pi + 8)}{2\pi + 8} [/tex]
[tex] \frac{p}{2\pi + 8} = r [/tex]
[tex] r = \frac{p}{2\pi + 8} [/tex]
Assume that both inspectors inspect every item and that if an item has no flaw, then neither inspector will detect a flaw.
a. Assume that the probability that an item has a flaw is 0.10. If an item is passed by the first inspector, what is the probability that it actually has a flaw?
b. Assume that the probability that an item has a flaw is 0.10. If an item is passed by both inspectors, what is the probability that it actually has a flaw?
Answer:
a) 0.011
b) 0.0032
Step-by-step explanation:
first lets say A₁ denotes the event that first inspector detects a flaw and A₂ is event that the law will be detected by the second inspector,
also let B denote the event that an item has a flaw.
a)
Given that;
P(B) = 0.1
so
P(A₁ / B ) = 0.9, P(A₂ / B ) = 0.7
using Baye's rule, the probability that an item has a flaw if it was passed by the first inspector is;
P(B / A₁ⁿ ) = [P(A₁ⁿ / B ) P(B)] / [ P(A₁ⁿ / B ) P(B) + P(A₁ⁿ / Bⁿ ) P(Bⁿ) ]
the probability that the first inspector will not detect the flaw if it actually exist is;
P(A₁ⁿ / B ) = 1 - P(A₁ / B )
= 1 - 0.9
= 0.1
Since there are no false detections, the probability that the first inspector will not detect the flaw, given that item does not have flaws is;
P(A₁ⁿ / Bⁿ ) = 1.0
so the probability that the item has flaw if it was passed by the first inspector is;
P(B / A₁ⁿ ) = [(0.1) (0.1)] / [ (0.1 ) (0.1) + (1.0) (1 - 0.1) ]
= 0.01 / ( 0.01 + 0.9)
= 0.01 / 0.91
= 0.011
b)
Also by Bayes rule, the probability that the item has a flaw if it was passed by both inspectors is;
P(B / A₁ⁿ ∩ A₂ⁿ) = [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B)] / [ P(A₁ⁿ ∩ A₂ⁿ / B) P(B) + P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) P(Bⁿ)]
Now since inspectors function independently, the probability that both inspectors will not detect the flaw if it actually exists is;
P(A₁ⁿ ∩ A₂ⁿ / B) = P(A₁ⁿ / B) P(A₂ⁿ / B)
= ( 1 - 0.9 ) ( 1 - 0.7)
= 0.1 * 0.3
= 0.03
since there are no false detections, the probability that both inspectors will not detect the flaw, given that item does not have a flaw is;
P(A₁ⁿ ∩ A₂ⁿ / Bⁿ) = 1.0
therefore
the probability that the item has a flaw if it was passed by both inspectors is;
P(B / A₁ⁿ ∩ A₂ⁿ) = [(0.03)(0.1)] / [(0.03)(0.1) + (1.0)(1-0.1)
= 0.003 / 0.93
= 0.0032
f(x) = (x + 1)2 – 4 g(x) = –4 |x + 1| Which statement compares the ranges of the functions? The ranges of both f(x) and g(x) are limited to y ≥ –1. The ranges of both f(x) and g(x) are limited to y ≤ –1. Since the range of f(x) is limited to y ≤ 0 and the range of g(x) is limited to y ≥ –4, the ranges overlap for the values –4 ≤ y ≤ 0. Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.
Answer:
Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.
Step-by-step explanation:
From Function theory we get that range of a function is the set of values of [tex]y[/tex] so that exist a respective value of [tex]x[/tex], whose set is the domain of the function. Let be [tex]f(x) = (x+1)^{2}[/tex] and [tex]g(x) = -4\cdot |x+1|[/tex], the ranges of each function are, respectively:
f(x):
From Real Algebra we know that the square of every number is a non-negative number, which means that:
[tex](x+1)^{2} \geq 0[/tex]
[tex](x+1)^{2}-4 \geq -4[/tex] (Compatibility with addition)
[tex]f(x) \geq -4[/tex] (Definition/Result)
The range of [tex]f(x)[/tex] is: [tex]Ran \{f(x)\} = [-4, +\infty)[/tex]
g(x):
From Real Algebra we know that a absolute value leads to non-negative number, which means that:
[tex]|x+1|\geq 0[/tex]
[tex]-4\cdot |x+1| \leq 0[/tex] ([tex]a> b \longrightarrow a \cdot c < b\cdot c[/tex], if [tex]c < 0[/tex])
[tex]g(x) \leq 0[/tex] (Definition/Result)
The range of [tex]g(x)[/tex] is: [tex]Ran\{g(x)\} = (-\infty, 0][/tex]
If we compare each range, we came into the conclusion that:
[tex]-4 \leq y \leq 0[/tex].
Thus, correct answer is: Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.

Fatima earned an 85 average in her science class. The average is based on 6 tests that she takes over the span of the marking period. On her first four tests she earned an 83, a 78, an 87, and an 80. On her sixth test she scored 8 points more than on her fifth test.
Let x be the score Fatima received on her fifth test. Set up an equation using x that models this scenario. Solve the equation and state what Fatima earned on her fifth and sixth tests.
Answer:
Fifth Score = 87
Sixth Score = 95
Step-by-step explanation:
Given
[tex]Average = 85[/tex]
[tex]Scores = 83, 78, 87, 80[/tex]
[tex]Fifth\ score = x[/tex]
[tex]Sixth\ Score = 8 + x[/tex]
Required
Set up an equation
Solve for the fifth and sixth score
Average is calculated as thus:
[tex]Average = \frac{\sum x}{n}[/tex]
[tex]Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
Substitute 85 for Average
[tex]85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
[tex]85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}[/tex]
[tex]85 = \frac{336+ 2x}{6}[/tex]
Multiply both sides by 6
[tex]85 * 6 = 336 + 2x[/tex]
[tex]510= 336 + 2x[/tex]
Solve for 2x
[tex]2x = 510 - 336[/tex]
[tex]2x = 174[/tex]
Solve for x
[tex]x = 174/2[/tex]
[tex]x = 87[/tex]
Hence:
[tex]Fifth\ Score = 87[/tex]
[tex]Sixth\ Score = 87 + 8[/tex]
[tex]Sixth\ Score = 95[/tex]

Suppose you have a 6-face unfair dice with numbers 1,2,3,4,5,6 on each of its faces. If the probability distribution of throwing a number up is as follows:
1 with probability 1/12
2 with probability 1/12
3 with probability 1/12
4 with probability 1/12
5 with probability 1/12
6 with probability 1/2
Which of the following statement is correct?
a. The mathematical expectation of the dice throwing a number up is 3.5
b. The mathematical expectation of the dice throwing a number up is 6
c. The mathematical expectation of the dice throwing a number up is 4.25
d. This is not a proper probability distribution because all the probabilities do not sum up to one
Answer:
D is correct
Step-by-step explanation:
Here, we want to select which of the options is correct.
The correct option is the option D
Since the die is unfair, we expect that the probability of each of the numbers turning up
will not be equal.
However, we should also expect that if we add the chances of all the numbers occurring together, then the total probability should be equal to 1. But this does not work in this case;
In this case, adding all the probabilities together, we have;
1/12 + 1/12 + 1/12 + 1/12 + 1/12 + 1/2
= 5(1/12) + 1/2 = 5/12 + 1/2 = 11/12
11/12 is not equal to 1 and thus the probability distribution cannot be correct

Answer:
4140 pieces
Step-by-step explanation:
This is true because we would have to multiply the number of jigsaw puzzles and how many pieces each on of them had to see how many pieces they put together in all.
To set up the equation we would do 345 times 12,
if you calculate it, the answer would be 4140.
