At 6 am temperature was 71 degrees and rises 4 degrees per hour then at 9 am temperature reach 83 degrees.
As given in the question,
On Thursday at 6 am temperature = 71 degrees
Rise in temperature = 4 degrees per hour
Temperature at
7 am = 71+ 4
= 75 degrees
8am = 75 + 4
= 79 degrees
9am = 79 +4
= 83 degrees
Therefore, at 6 am temperature was 71 degrees and rises 4 degrees per hour then at 9 am temperature reach 83 degrees.

What do we mean by the distance formula?Distance is a numerical measure of the distance between two objects or points. The distance can be a physical length or an estimate based on other criteria in physics or everyday usage. The distance between two points A and B are sometimes denoted as |AB|.The distance formula: d = rtSo,
To begin, consider the distance formula: d = rtDividing by the coefficient of t yields the following equation for t: t = d/rRyan's rate of 4 miles per hour can be voiced in minutes as 4 miles per 60 minutes.
Ryan's time:
t = (12 mi)/(4 mi/60 min) = 12·60/4 min = 180 minTherefore, (B) 108 minutes is Ryan's time.

Frank was born in 1933 and died in 1946 at the age of 57. How can this be?
Answer:
Frank was born in 1933 and died in 1946 at the age of 57. 1933 and 1946 are not years but just room or ward numbers.
EXPLANATION:
The numerical 1933 and 1946 do not signify the year of birth or death. No where in the question is the word 'years' mentioned. Thus 1933 signifies either the room number or the ward number of the hospital Frank was born in.
Similarly 1946 is the room or ward number where Frank died. Hence his age is irrelevant with respect to 1933 and 1946. His related age of 57 thus has nothing to do with them.
Answer:
The numerical 1933 and 1946 do not signify the year of birth or death. Nowhere in the question is the word ‘years’ mentioned. Thus 1933 signifies either the room number or the ward number of the hospital Frank was born in.

Factor completely: 5n^2 - 80
Answer:
Step-by-step explanation:
Factoring 5n2-9n-2
The first term is, 5n2 its coefficient is 5 .
The middle term is, -9n its coefficient is -9 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 5 • -2 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is -9 .
-10 + 1 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 1
5n2 - 10n + 1n - 2
Step-4 : Add up the first 2 terms, pulling out like factors :

Initial estimates of the probabilities of events are known as _____ probabilities.
Initial estimates of the probabilities of events are known as prior probabilities.
Prior probability, in Bayesian statistics, is the probability of an event before new data is collected. This is the best rational assessment of the probability of an outcome based on the current knowledge before an experiment is performed.
The prior probability of an event will be revised as new data or information becomes available, to produce a more accurate measure of a potential outcome. That revised probability becomes the posterior probability and is calculated using Bayes' theorem. In statistical terms, the posterior probability is the probability of event A occurring given that event B has occurred.
The prior probability is the probability assigned to an event before the arrival of some information that makes it necessary to revise the assigned probability. The revision of the prior is carried out using Bayes' rule. The new probability assigned to the event after the revision is called posterior probability.
Initial estimates of the probabilities of events are known as prior probabilities.

From the first option we can see that -5,5,-5,5… dose not follow any sequence of arithmetic.
if we take the 18,5.5, –7, –19.5, which are the digits from the second option and if we find their differences we will get 12.5
Then if we take the numbers from the 16, 32, 48, 64 and find the differences between the first two numbers as well as the last two numbers then we will have 16.

The domain and the range of the reciprocal function are the set of all real numbers. True or false?.
False. All real numbers, with the exception of 0 because f (0) = 1 0, fall inside the reciprocal function's domain and range. Y cannot be 0 if x cannot, either.
What are real numbers?In mathematics, a real number is a quantity that may be represented by an endless number of decimal expansions. In contrast to the natural numbers 1, 2, 3,... that result from counting, real numbers are used in measurements of continuously varying quantities such as size and time. They are distinguished from imaginary numbers, which use the symbol I or the square root of 1, by the word "real." A complex number has a real (1) and an imaginary I component, like 1 + i. The positive and negative integers, as well as the fractions created from them (also known as rational numbers), as well as the irrational numbers, are all real numbers.
Contrary to rational numbers, whose decimal expansions always contain a digit or group of digits that repeats itself, such as 1/6 = 0.16666... or 2/7 = 0.285714285714, irrational numbers have decimal expansions that do not repeat themselves. Since there is no regularly repeating group in the decimal produced as 0.42442444244442, it is irrational.

The Second and third car seats are appropriate for a 32-ib child
The first car :
The range 30 ≤x< 32
So it is not possible for a car seat appropriate for a 32-ib child.
The second car:
The range 15<x <40
So it is possible for a car seat appropriate for a 32-ib child.

2x + 3y = 1200, 3x + 2y = 1300. what is the value of 5x + 5y using substitution method
The value of 5x + 5y is 2500 by substitution method.
According to the given question.
We have two equations
2x + 3y = 1200
3x + 2y = 1300
Since, we have to find the value of 5x + 5y by substitution method.
From equation 2x + 3y = 1200
2x = 1200 - 3y
⇒ x = [1200 -3y]/2
Substitute the value of x in 3x + 2y = 1300.
⇒ 3[1200 - 3y]/2 + 2y = 1300
⇒ 3[600 -3y/2] + 2y = 1300
⇒ 1800 - 9y/2 + 2y = 1300
⇒ 1800 + (4y - 9y)/2 = 1300
⇒ (4y - 9y)/2 = -500
⇒ -5y = -1000
⇒ y = 200
So,
x = [1200 - 600]/2 = 600/2 = 300
Thereofore, the value of 5x + 5y by substitution method is given by
5(300) + 5(200)
= 1500 + 1000
= 2500
Hence, the value of 5x + 5y is 2500 by substitution method.
