Find the equation of the line graphed below. Write the equation in the form y=mx+b and identify m and b.
Answers
Answer:
m = 1/2 and b = 1.
Step-by-step explanation:
The y intercept (b) is at y = 1 so we have
y = mx + 1 so b = 1
The m is the slope of the line.
The graph passes through the point (4, 2)
From the graph, the slope = 2/4 = 1/2.
So it is y = 1/2x + 1.

Tom can type 120 words in 3 minutes. What is the ratio of words typed to minutes? Question 2 options: A. 1 : 117 B. 1 : 40 C. 40 : 1 D. 117 : 1
Answers
Answer:
C
Step-by-step explanation:
Since he writes 120 words in 3 minutes, we know that Tom will write 120 / 3 = 40 words in 1 minute, therefore the ratio is 40 : 1. It's not 1 : 40 because the question is asking for the ratio of words typed to minutes, not minutes to words typed.

Is a temperature of 35 degrees Fahrenheit as cold as a temperature of -35 degrees Fahrenheit?
Answers
Answer:
Step-by-step explanation:
Definitely not. -35 degrees is far below freezing (+32 degrees). On the other hand, +35 degrees is very warm indeed.
No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.
We have temperature in degrees Fahrenheit.
We have to investigate - " Is a temperature of 35 degrees Fahrenheit as cold as a temperature of -35 degrees Fahrenheit ".
What is the formula to convert Fahrenheit to degrees Celsius ?The formula is -
(°F − 32) × 5/9 = °C
According to the question -
Assume that -
A = 35°F = 1667 °C
B = -35°F = -37.2222 °C
The temperature 35°F represents very very high temperature (hot) whereas the temperature -35°F represents very very low temperature (cold).
Hence, No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.

A plan traveled for a total of 2,773 miles over the course of 8 hours. Heading south, the plan traveled at an average speed of 344 miles per hour and heading west. It traveled at an average speed of 351 miles per hour. For how many hours was the plane heading south?
Answers
Answer:
5 hours
Step-by-step explanation:
Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...
s + w = 8 . . . . . . total trip time
344s + 351w = 2773 . . . . total mileage (using d = s·t)
By Cramer's rule, we can find the value of s as ...
s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5
The plane was heading south for 5 hours.

According to a survey, 10% of Americans are afraid to fly. Suppose 1,100 Americans are sampled. What is the probability percentage that 121 or more Americans in the survey are afraid to fly
Answers
Answer:
0.137.
Step-by-step explanation:
Given that
Sample size = 1100
Afraid to fly = 10 %
Mean = n x p
Mean = 1100 x 0.1 = 110
Variance = n p q
Variance = 1100 x 0.1 x 0.9 = 99
Standard deviation = [tex]\sqrt{n\times p\times q}[/tex]
S.D.=[tex]\sqrt{1100\times 0.1\times 0.9}[/tex]
S.D.=9.94
By using Normal distribution
[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
[tex]Z=\dfrac{121-110}{9.94}[/tex]
Z=1.16
[tex]P(X>121)=P(Z>1.16)=1-0.8643\\P(X>121)=0.137\\[/tex]
Thus the answer will be 0.137.
Assuming that workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year, find the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.
Answers
Answer:
The probability is [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]
Step-by-step explanation:
From the question we are told that
Workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year
Generally the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000 is mathematically represented as
[tex]P(\$20,000 < X \$35,000) = \frac{ 35000 - 20000}{ 40000 - 150000}[/tex]
=> [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]
Using the uniform distribution, it is found that there is a 0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.
An uniform distribution has two bounds, a and b.
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
In this problem, uniformly distributed between $15,000 and $40,000, hence [tex]a = 15, b = 40[/tex].
The desired probability is:
[tex]P(20 \leq X \leq 35) = \frac{35 - 20}{40 - 15} = 0.6[/tex]
0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.

x = 0.5555552) --------------
10x = 5.5555553) --------------
10 x - x = 5.555555 - 0.5555559x = 5x = 5/9So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Suppose you start with a full tank of gas (18 gallons) in your truck. After driving 6 hours, you now have 8 gallons left. If x is the number of hours you have been driving, then y is the number of gallons left in the tank. At what rate is your truck using gas
Answers
Step-by-step explanation:
y is the number of gallons left in the tank.
x is the number of hours you have been driving
Rate of consumption of gas
= (18 - y / x)
= 5 / 3 gallon per hour
= 6.309 L / hr
The rate at which your truck is using gas is 5/3 gallons per hour.
What is rate at which your truck is using gas?The rate at which your truck is using gas is calculated as follows;
Given that after 6 hours of driving, you have 8 gallons left in the tank, we can set up the following equation using the two given data points:
(Initial gallons - Remaining gallons) / (Initial time - Time elapsed) = (Change in gallons) / (Change in time)
The equation becomes;
Rate = (18 gallons - 8 gallons) / (6 hours - 0 hours)
Rate = (18 - 8) / 6
Simplifying this equation, we get:
Rate = 10 / 6
Rate = 5 / 3
Therefore, the rate at which your truck is using gas is 5/3 gallons per hour.

GRIDDED RESPONSE Mark got 18 out of 25
questions correct on his science test. What percent
of the questions did he get correct?
Answers
he got 0.08 percent questions correct
Answer:
72%
Step-by-step explanation:
A percentage is a number out of 100. For example, 32/100 is 32%. What you want to do with percentages is multiply the denominator of a fraction so it becomes 100 and multiply that same number to the numerator. Sort of like a ratio!
If Mark got 18/25, we can multiply 25 by 4 to get 100 as the denominator.
Since you multiplied the denominator by 4, you have to multiply the numerator by 4 as well.
18 times 4= 72. So the numerator is 72 and the denominator is 100. The fraction is 72/100, which is 72% since it is out of 100.
