Joe worked 42 hours and packed 48 cartons. Bob worked 14 hours and packed 16 cartons. Did Joe and Bob work at the same rate?
Answer:
Yes
Step-by-step explanation:
if you simplify. 42/48. 7/8
if you simplify 14/16 is 7/8 So they are equal
If Joe worked 42 hours and packed 48 cartons and Bob worked 14 hours and packed 16 cartons, Joe and Bob worked at the same rate.
To determine if Joe and Bob worked at the same rate, we need to compare the number of cartons they packed per hour. We can calculate the rate by dividing the number of cartons packed by the number of hours worked.
For Joe:
Rate = Number of cartons packed / Number of hours worked
Rate = 48 cartons / 42 hours ≈ 1.143 cartons per hour
For Bob:
Rate = Number of cartons packed / Number of hours worked
Rate = 16 cartons / 14 hours ≈ 1.143 cartons per hour
Both Joe and Bob have a packing rate of approximately 1.143 cartons per hour.
They packed almost the same number of cartons per hour on average. This indicates that their packing efficiency is similar, regardless of the difference in the total number of hours or cartons packed.

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
Explanation:
Before solving the problem, we should understand what is the length that corresponds to one notch in the graph.
We see that there are 3 notches between 0 and 6, and that the length of the notches is constant: so, each notch corresponds to the same length. Since we have 3 notches, the length of each notch is
6/3 = 2
now, we have,
Since the car is located at the first notch, it means that its position is:
x = 1*2 = 2
Hence, The solution is, c. 2, is the position of the car.

If a system of linear equations has one solution, what does this mean about the two lines?
A. The same line
B. Parallel lines
C. Intersecting lines
Answer:
It means two lines intersected.
C is correct
Hope this helps!
:)
If a system of linear equations has one solution, this means that the lines are intersecting lines
Intersecting lines are lines that meet at a point.
For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution
For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation
Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

From the sample population of students with blond hair, what is the approximate value of the relative frequency of students with green eyes? A. 0.25 B. 0.33 C. 0.27 D. 0.07
Don't quote me on this but I think the answer is C. 0.27
The required approximate value of the relative frequency of students with green eyes is 0.27. Option C is correct.
From the sample population of students with blond hair, the approximate value of the relative frequency of students with green eyes is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of students having green eyes with blond hair =21
Total number of students having blond hair = 78
relative frequency of students with green eyes = 21/78
= 0.27
Thus, the required approximate value of the relative frequency of students with green eyes is 0.27.

Step-by-step explanation:
It says it's a polynomial and that based on the number of terms. So right then you can cancel out cubic and quadratic because they aren't polynomials. Also:
Cubic is just a variable with the exponent of 3. Examples:
[tex]x^3,y^3,z^3[/tex]
Binomial is a polynomial with 2 terms. Examples:

A triangle has sides with lengths of 6 yards, 8 yards, and 10 yards. Is it a right triangle?
Answer:
Step-by-step explanation:
so, by the Pythagorean theorem
If it is a right triangle:
a^2 + b^2 = c^2
so,
6^2 = 36
8^2 = 64
10^2 = 100
okay, now we plug these into the equation
36 + 64 = 100
so yes, it is a right triangle.

Answer:
No, it's not a right triangle.
Explanation:
If you think about it a right triangle has 2 equal sides. So no this isn't a right traingle.

Answer:
The mean absolute deviation (MAD) of her Math scores would be 1.2.
Step-by-step explanation:
Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1
7.1 - 5.4 = 1.7

Solve for x: 2800 = 400 * 2^10x
it should be x=log(7)/10*log(2) and x=in(7)/10*in(2)
so B and D
The required solution for the expression is [tex]x = ln7/(10*ln2)[/tex]. Option D is correct
To solve [tex]2800 = 400.2^{10x}[/tex] for x.
what is an exponential function?The function which is in format f(x) = [tex]a^x[/tex] where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
[tex]2800 = 400.2^{10x}[/tex]
[tex]2800/400= 2^{10x}[/tex]
[tex]7=2^{10x}[/tex]
taking log on both sides.
[tex]log_27=10x\\x=log_27/10\\x = log_e7/(10*log_e2)\\x =ln7/(ln2*10)[/tex]
(By properties of logarithm log can be separated to common base e)
The required solution for the expression is [tex]x = ln7/(10*ln2)[/tex].

John recorded the weight of his dog Spot at different ages as shown in the scatter plot below.
Part A:
Write an equation that would describe the line of best fit.
Part B:
Using the line of best fit, make a prediction of Spot's weight after 18 months.
Answer:
A) y = 1.875x + 1.25
B) 35 pounds
Step-by-step explanation:
A) We need two points to define a line. To find an equation that would describe the line of best fit, we can use one of the first points and one of the last points. Let's use (2, 5) and (10, 20).
General equation of a line:
y = mx + b
Slope of the line:
m = (20 - 5)/(10 - 2) = 1.875
y-intercept is found replacing a known point and the slope into the general equation:
5 = 1.875*2 + b
b = 5 - 1.875*2 = 1.25
The final equation is:
y = 1.875x + 1.25
where y represents weight (in pounds) and x represents age (in months)
B) At x = 18:
y = 1.875*18 + 1.25 = 35
