People living in Fairbanks drink 3600 cups of hot chocolate in a day when the temperature is O' Fahrenheit. For each rise of 1"F, their consumption decreases by 120 cups. Questions 14-16 Write an equation that can be used to represent the number of cups, C, of hot chocolate drank as a function of degrees, F, Fahrenheit? C = 3600 - 120F Your answer 14. How many cups would they drink at 5°F?* 5 points Your answer This is a required question 15. How many cups would they drink at 25°F?* 5 points Your answer
Answer:
a. The expression that represents the number of cups of hot chocolate drunk per day as a function of degrees Celsius is
y = -30x + 3600 pr the equivalent y = 3600 - 30x
b. How many cups would they drink at 5 degrees Celsius?
x = 5 --> y = 3600 - 30 X 5 --> y = 3600 - 150 --> y = 3450
c. How many cups would they drink at 25 degrees Celsius?
x = 25 --> y = 3600 - 30 X 25 --> y = 3600 - 750 --> y = 2850
d. Write an equation to determine the temperature if 3000 cups of hot chocolate were consumed in a day.
y = 3000 --> 3000 = 3600 - 30x
e. Solve the equation to find the temperature if 3000 cups of hot chocolate were consumed in a day.
--> 3000 = 3600 - 30x --> 3000 - 3000 + 30x = 3600 - 30x - 3000 + 30x --> 30x + 600 --> 30x/30 = 600/30 --> x = 20
f. Is this answer reasonable? Explain.
It is very reasonable.
At 0 degree C. they drink 3600 cups.
As the temperature increases, hot chocolate consumption decreases.
At 5 degree C. they drink less hot chocolate: 3450 cups.
Since 20 degree C. is even warmer, they should drink even less at 20 degree C., but not as little as the 2850 cups they drink on those very warm 25 degree C. days.
Step-by-step explanation:
We need to name/define variables:
y = number of cups of hot chocolate consumed in a day in Fairbanks.
x = temperature in degrees Celsius
"For each rise of 1 degrees Celsius, their consumption decreases by 30 cups per day."
That tells you that y is a linear function of x, so we should be able to write it as
y=mx + b with some constants for slope, m, and y-intercept, b.
It also tells you that the slope is m=-30.
"People living in Fairbanks drink 3600 cups of hot chocolate per day when the temperature is 0 degrees Celsius."
That gives you the value of y when x=0, which is the y-intercept,
b=3600

What do you mean by Money?Money is a good that is widely acknowledged as a means of economic exchange. It serves as the medium for expressing values and pricing. It is the primary indicator of wealth since it moves from person to person and country to country, allowing trade.
A pledge made to another party stating whether they will or won't carry out a specific activity in the future. For instance, I'll give you $3,500 in exchange for your car. of oneself. In most cases, it reflects the conditions of the offer—a declaration made through words or deeds that both parties accept the terms of the contract.
A contract must contain several characteristics in order to be legitimate and recognized by the common law, including an offer, acceptance, consideration, the desire to establish legal relations, authority and ability, and certainty. A contract cannot be enforceable by the courts and is not legally binding if it lacks these components.
Therefore, Option (B) is correct. A written contract is not legally binding until it is signed by all parties involved.

This question is incomplete, the complete question is;
Radio frequency identification (RFID) is an electronic scanning technology that can be used to identify items in a number of ways. One advantage of RFID is that it can eliminate the need to manually count inventory, which can help improve inventory management. The technology is not infallible, however, and sometimes errors occur when items are scanned. The probability that a scanning error occurs is 0.0062.
- find the probability that the number of items scanned incorrectly is between 14 and 25, inclusive, from the next 4600 items scanned.
Answer:
the probability that the number of items scanned incorrectly is between 14 and 25, inclusive, from the next 4600 items scanned is 0.2819
Step-by-step explanation:
Given that;
n = 4600
p = 0.0062
now mean of distribution μ = n × p = (4600 × 0.0062) = 28.52
standard deviation σ = √(np(1-p)) = √(4600 × 0.0062(1 - 0.0062 )) = 5.3238
for normal distribution z-score = (X-μ) / σx
therefore from the normal approximation of continuity correction and binomial distribution;
probability = P(13.5 < X < 25.5)
= P( -2.82 < Z < -0.57 )
= 0.2853 - 0.0024
= 0.2819
therefore the probability that the number of items scanned incorrectly is between 14 and 25, inclusive, from the next 4600 items scanned is 0.2819

Answer:
17
Step-by-step explanation:
The answer is 17 because the operation PEMDAS
Answer:
17
Step-by-step explanation:
20/ 4+6x2 can be simplified. First, you can divide 20 by 4 because of the order PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) 20 divided by 4 is 5. You can then multiply 6 and 2 which gives you 12. Therefore, your equation is down to 5+12. You can add those two and you get 17 :) Hope this helps!! :D ~Happy Halloween~

The p-value for the test statistic: [tex]Z_o=-1.96[/tex] is 0.025.
In statistics, the p-value is a measure that quantifies the strength of evidence against a null hypothesis. It represents the probability of observing a result as extreme as, or more extreme than, the one obtained in a statistical test, assuming that the null hypothesis is true.
The null hypothesis, denoted as H₀, represents the default or initial assumption that there is no significant difference or relationship between variables or no effect of a treatment. The alternative hypothesis, denoted as H₁, suggests the existence of a significant difference or relationship.
The p-value for the test statistic: [tex]Z_o=-1.96[/tex]:
p-value = P{[tex]Z_o < -1.96[/tex]}
= 0.025.

What is a linear equation ?A linear equation is an algebraic equation of highest degree 1.
According to the given question A contractor needs to buy nails to build a house.
The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails.
The contractor bought 5 more large boxes than small boxes,So assuming he bought x no. of small boxes.
∴ He bought (x+5) nos. of large boxes.
So, 50(x) + 350(x+5) = 2550.
50x + 350x + 1750 = 2550.
400x = 2550 - 1750.
400x = 800.
x = 2.
∴ Large no. of boxes he purchased is 7.

Trigonometric Identities
Before we prove the given identity, we need to recall:
[tex](a+b+c)^2=a^2+b^2+c^2+2ab+2ac+2bc[/tex]
We have to prove that:
[tex](1+\sin\theta+\cos\theta)^2=2(1+\sin\theta)(1+\cos\theta)[/tex]
Let's expand the square on the left side as indicated in the formula above:
[tex](1+\sin\theta+\cos\theta)^2=1^2+\sin^2\theta+\cos^2\theta+2\sin\theta+2\cos\theta+2\sin\theta\cos\theta[/tex]
Recall the fundamental trigonometric identity:
[tex]\sin^2\theta+\cos^2\theta=1[/tex]
Substituting and operating:
[tex](1+\sin\theta+\cos\theta)^2=2+2\sin\theta+2\cos\theta+2\sin\theta\cos\theta[/tex]
Factoring by 2:
[tex](1+\sin\theta+\cos\theta)^2=2(1+\sin\theta+\cos\theta+\sin\theta\cos\theta)[/tex]
Factoring cos θ in the last two terms:
[tex](1+\sin\theta+\cos\theta)^2=2[1+\sin\theta+\cos\theta(1+\sin\theta)][/tex]

What is average?
The ratio of total sum in a given set to all the values in the data set is the mean value, which is the definition of the average. In mathematics, the central value of the a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to a number of units in the list. In terms of statistics, the term "mean" also refers to the average of a particular set of numerical data. The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3. The central value of 2, 3, and 4 in this instance is 3, so. Finding the mean value of the a group of numbers is the definition of average.
According to question,
[tex]\frac{86+88+78+x}{4} = 83[/tex]⇒ [tex]x = 80[/tex]
Hence, Gill can score 80.

Find the angle 1 in this photos
Answer:
2. m∠1 = 129°
3. m∠1 = 37°
Step-by-step explanation:
We know that the sum of all interior angles in a triangle adds up to 180°.
2. To find measure 1 for problem 2, we can see that ∠1 is a supplementary angle with the interior angle in side
180°-(67°+62°)
180°-129°
51°
Now that we found the missing interior angle, we can find ∠1
180°-51° = 129°
m∠1 = 129°
3. Same thing as well for this problem except we're going to be going reverse we need to find the supplementary angle first, then we can find m∠1.
180°-152° = 28°
Now that we found the interior angle, we can find m∠1
180° - (115°+28°)
180°-(143°)
37°
m∠1 = 37°
