Answer: 32°F ≤ x ≤ 212°F
Step-by-step explanation:
Let's use the letter x to denote our variable, the temperature.
We know that water starts freezing at 32°F (this is the transition point, so when liquid water reaches this point it will remain at that temperature until all the water changes tho the solid phase, ice).
Then the minimum temperature of the liquid water is 32°F, we can write this as:
32°F ≤ x
We also know that at 212°F the water starts boiling, this means that when liquid water reaches the temperature of 212°F, any increase in energy (or any quantity of heat that you give to the water) will only change the phase of the water, so we can have liquid water at the temperature of 212°F, and the temperature will only increase when all the water is transformed into vapor.
We write this as:
x ≤ 212°F
Now, writing both inequalities we have:
32°F ≤ x ≤ 212°F

Write an equation of the line that contains the given point and has the given slope
(-1, 2), slope is -3
Answer:
y=-3x-1
Step-by-step explanation:
Use point-slope form:
(y-2)=-3(x+1)
y-2=-3x-3
y=-3x-1
Y=1/2x+5;2y=2x+4
Solve by using the substitution method.
The equations have a solution of x = 6 and y = 8.
We will initially tackle one condition for one factor and afterward substitute that articulation into the other condition to utilize the replacement technique to settle the arrangement of conditions.
Let's begin with the fundamental condition: Y = (1/2)x + 5. By isolating it on one side, we can solve this equation for Y:
We will currently substitute method this articulation for Y in the subsequent condition: Y = (1/2)x + 5 2y = 2x + 4.
2(1/2)x + 5 = 2x + 4, which makes the equation easier to understand:
Isolating x from one side of the equation is the next step: x + 10 = 2x + 4. We acquire: by removing x from each side.
Since we have 10 = x + 4, we can take away 4 from the two sides to get:
6 = x We have discovered that the value of x is 6. To determine the value of y, we return this value to the initial equation:
Because Y = (1/2)(6) + 5 Y = 3 + 5 Y = 8, the equations have a solution of x = 6 and y = 8.

(2pts each) The probability that a disorganized professor shows up late to class on a given day is 0.47 and the probability that he sleeps through his alarm is 0.53. Further, given that he sleeps through is alarm rises in price, the probability that he shows up late is 0.57. a. What is the probability that either the Professor shows up late to class, or he sleeps through his alarm, or both? (Round your answer to 2 decimal places.) Let A denote the event that the professor shows up late to class and let B denote the event that he sleeps through his alarm. b1. Are events A and B mutually exclusive? Yes because P(A∣B)=P(A) Yes because P(A∩B)=0. No because P(A∣B)
=P(A). No because P(A∩B)
=0. b2. Are events A and B independent? Yes because P(A∣B)=P(A). Yes because P(A∩B)=0. No because P(A∣B)
=P(A). No because P(A∩B)
=0.
The probability that either the professor shows up late to class, or he sleeps through his alarm, or both events occur is approximately 0.43. It is inconclusive whether events A and B are independent.
To find the probability that either the professor shows up late to class, or he sleeps through his alarm, or both events occur.
We can use the principle of inclusion-exclusion to find the probability of the union of two events, A (professor shows up late) and B (professor sleeps through his alarm). The formula is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Given probabilities:
P(A) = 0.47 (probability of showing up late)
P(B) = 0.53 (probability of sleeping through the alarm)
P(A ∩ B) = 0.57 (probability of showing up late given sleeping through the alarm)
Using the formula, we have:
P(A ∪ B) = 0.47 + 0.53 - 0.57 = 0.43
Therefore, the probability that either the professor shows up late to class, or he sleeps through his alarm, or both events occur is approximately 0.43.
To determine whether events A (professor shows up late) and B (professor sleeps through his alarm) are mutually exclusive.
Events A and B are mutually exclusive if and only if the probability of their intersection, P(A ∩ B), is equal to zero.
In the given question, it states that the probability that he shows up late given he sleeps through his alarm is 0.57. This indicates that P(A ∩ B) is not equal to zero.
Therefore, events A and B are not mutually exclusive.
To determine whether events A (professor shows up late) and B (professor sleeps through his alarm) are independent.
Events A and B are independent if and only if the conditional probability of A given B, P(A|B), is equal to the marginal probability of A, P(A), and vice versa.
In the given question, it does not provide any information about the conditional probability P(A|B) or P(B|A). Therefore, we cannot determine whether events A and B are independent based on the given information.
Therefore, it is inconclusive whether events A and B are independent.

Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 feet per second. \text{Will runs 308 feet in 26 seconds.} Will runs 308 feet in 26 seconds. \text{Ron runs 1 mile in 551 seconds.} Ron runs 1 mile in 551 seconds. \text{Debbie runs 658 feet in 1 minute.} Debbie runs 658 feet in 1 minute.
Answer:
Brooke runs the fastest.
Step-by-step explanation:
Brooke runs 13 feet per second.
Therefore, speed of Broke = 13 feet per sec.
Will runs 308 feet in 26 seconds.
Speed of Will = \(\frac{\text{Distance}}{\text{Time taken}}\)
= \(\frac{308}{26}\)
= 11.85 feet per second
Ron runs 1 mile in 551 seconds.
1 mile = 5280 feet
Speed of Ron = \(\frac{5280}{551}\)
= 9.58 feet per second
Debbie runs 658 feet in 1 minute.
1 minute = 60 seconds
Speed of Debbie = \(\frac{658}{60}\)
= 10.97 feet per seconds
Here, speed of Brooke is the maximum.
Therefore, Brooke runs the fastest.

Dilate circle A by a scale factor of 2.
Translate circle A using the rule (x + 1, y − 1).
Rotate circle A 180° about the center.
Reflect circle A over the y-axis.
Answer:
A
Step-by-step explanation:
To show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have two circles:
Circle A has a center of (2, 3) and a radius of 5
Circle B has a center of (1, 4) and a radius of 10
The standard circle's equation can be written as:
(x - h)² + (y - k)² = r²
The equation for circle A:
(x - 2)² + (y - 3)² = 5²
The equation for circle B:
(x - 1)² + (y - 4)² = 10²
To show that circle A is similar to circle B:
It is required to perform the geometric transformation:
Dilate circle A by a scale factor of 2.
The radius of circle A is 5 units and after dilation by a scale factor of 2, the radius of the circle becomes 10 which is the radius of circle B.
Thus, to show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

G. X < 15
H. X less than/equal to 15
I. X > 15
Correct answer is H, On solving the provided question, we can say that inequality is graphed below is X less than/equal to x ≤ 15
Describe inequality.A relationship between two expressions or values that is not equal in mathematics is referred to as an inequality. Thus, inequity results from imbalance. In mathematics, an inequality establishes the connection between two non-equal numbers.
Egality and inequality are not the same. Use the not equal symbol most frequently when two values are not equal ().
Values of any size can be contrasted using a variety of inequalities. By changing the two sides until only the variables are left, many straightforward inequalities can be solved.
However, a variety of factors support inequality: Both sides' negative values are split or added. Exchange the left and the right.
As, the graph is pointing backwards from 15,
⇒ the values are less than equal to 15,
⇒ the inequality which follows criteria is x ≤ 15

When the new book units of fire was released, Johnathan decided to read it in one sitting for his book report. He started at 11:00 a.m. on Saturday morning and read until 8:00 p.m. that night, for a total of 9 hours. For school, however, he needed to record the exact number of minutes he spent reading.
To figure out how many minutes he read, what is a conversion ratio he should use?
\(A. \frac{9.30 minutes}{1 hour}\)
\(B. \frac{1 hour}{60 minutes}\)
\(C. \frac{60 minutes}{1 hour}\)
\(D. \frac{60 hours}{1 minute}\)
Answer:
9 hr * 60 min/hr = 540 min. 540 min * 60 sec/min = 32,400 sec. Use the method described by panic mode: round the number down until there is only one non-zero digit left. Here, 32,400 rounds down to 30,000. Now count the number of zeroes; the result is the order of magnitude: 4. (You see this in scientific notation also: 30,000 = 3 × 10^4.)
