Answer:
P(black): 4/9
P(yellow): 2/9
P(orange): 3/9
Step-by-step explanation:
There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.
Answer:
5) 4/9
6) 2/9

14. A truck has a maximum load limit of 5000 gallons. Can it safely carry 600 bushels
of canola?
Answer:
It won't carry it safely
Step-by-step explanation:
truck capacity ? load value
5000 gallons ? 600 bushels
5000 gallons < 5585 gallons
600 bushels ie 5585 gallons is larger than 5000 gallons, which is the truck's capacity
A student is trying to calculate his semester average. He knows that his test average is an 80, his quiz average is a 72, homework is a 90, and classwork is a 93. If tests and quizzes are worth 30% each, and homework and classwork are worth 20% of his overall average, what is his average? Round to the nearest tenth.
What is the mean?
As per linear equation, the average of the student is 82.2.
The mean is 83.75.
What is a linear equation?A linear equation is an equation that contains one or multiple variable with the highest power of the variable is one.
The student got test average of 80, his quiz average of 72, homework of 90, and classwork of 93.
Test is worth of 30%.
Therefore, the weightage of test is
= 80 × 30%
= 24
Quiz is worth of 30%.
Therefore, the weightage of quiz is
= 72 × 30%
= 21.6
Homework is worth of 20%.
Therefore, the weightage of homework is
= 90 × 20%
= 18
Classwork is worth of 20%.
Therefore, the weightage of classwork is
= 93 × 20%
= 18.6
Therefore, the average of the student is
= (24 + 21.6 + 18 + 18.6)
= 82.2
Now, the mean is
= (80 + 72 + 90 + 93)/4
= 83.75

Answer:
y = 3
Step-by-step explanation:
All this question is asking is:
When x = 1, what does y equal?
To solve this problem, plug in 1 for x to get
[tex]y = \frac{1}{2} *6^1[/tex]
Then, simplify!
Any number to the first power is the same number, so [tex]6^1 = 6[/tex].
[tex]\frac{1}{2} * 6 = \frac{6}{2} = 3[/tex]
y = 3.

A biologist is studying the growth of a particular species of algae. She writes the fall inclusion to show the radius of the algae, f(d), in mm, after d days: f(d)=5(1.02)^d
Part A- When the biologist concluded her study, the radius of the algae was approximately 6.34mm. What is a reasonable domain to plot the growth function
Part B- What does the y-intercept of the graph of the function f(d) represent?
Part C- what is the average rate of change of the the function f(d) from d=4 to d=11, and what does it represent?
Answer:
Part A)
A reasonable domain to plot the growth function is:
[tex]0\leq d \leq 12[/tex]
Part B)
The y-intercept represents that when the biologist started her study, the radius of the algae was five millimeters.
Part C)
The average rate of change from d = 4 to d = 11 was about 0.11. This means that from the 4th day to the 11th, the radius of the algae grew, on average, at a rate of 0.11 mm per day.
Step-by-step explanation:
The radius of the algae f(d) in millimeters after d days is given by the function:
[tex]f(d)=5(1.02)^d[/tex]
Part A)
We know that the radius of the algae was approximately 6.34 mm when the biologist concluded her study. To find the reasonable domain, we can substitute 6.34 for f(d) and solve for d. Therefore:
[tex]6.34=5(1.02)^d[/tex]
Divide both sides by five:
[tex](1.02)^d=1.268[/tex]
Take the log of both sides with base 1.02:
[tex]\displaystyle d=\log_{1.02}1.268[/tex]
Using the Change of Base Property, evaluate for d:
[tex]\displaystyle d=\frac{\log 1.268}{\log 1.02}=11.9903...\approx 12[/tex]
So, the biologist concluded her study after 12 days.
Therefore, a reasonable domain to plot the growth function is:
[tex]0\leq d\leq 12[/tex]
Part 2)
The y-intercept of the function is when d = 0. Find the y-intercept:
[tex]f(0)=5(1.02)^{(0)}=5(1)=5[/tex]
Since d represent the amount of days after the study had begun, the y-intercept represents the radius of the algae on the initial day.
So, when the biologist started her study, the radius of the algae was five millimeters.
Part 3)
To find the average rate of change for a nonlinear function, we find the slope between the two endpoints on the interval.
We want to find the average rate of change of f(d) from d = 4 to d = 11.
Find the endpoints:
[tex]f(4)=5.4121...\text{ and } f(11)=6.2168...[/tex]
And find the slope between them:
[tex]\displaystyle m=\frac{f(11)-f(4)}{11-4}=0.1149...\approx 0.11[/tex]
Since f(d) measures millimeters and d measures days, this tells us that, on average, the radius of the algae grew by about 0.11 mm per day from the 4th day to the 11th day.
Which expressions are equivalent. Picture Provided. NO LINKS! NEED ANSWER ASAP
Answer:
B) 3^-5 (1 / 243) and D) 2^5 x 6^-5 (1 / 243)
Step-by-step explanation:
3 to the negative 5th power as a fraction is
1 / 243.
2 to the power of 5 multiplied by 6 to the power of negative 5 also equals 1 / 243.
Both expressions are equivalent to 2^5 / 6^5 because they equal the same thing (1 / 243).

Carlos is saving money to buy a set of golf clubs that cost $530. He already has $80.00 saved and can earn the rest of the money by mowing 15
lawns. If m represents how much he earns for mowing each lawn, which of the following equations can be solved to find how much Carlos is paid for
mowing each lawn?
Answer:
15m+80 would be the correct equation
Answer:
15*m=(530-80)
Step-by-step explanation:
30$ per lawn. 530-80=450. This gives us how much money he still needs to buy his gulf clubs. But, the question says that Carlos can earn the rest of the money ($450) by mowing 15 lawns.
Here's how we model that as an expression:
15m=(530-80)
15 lawns for m dollars would get him 530-80 (450) or the remaining amount.

Step-by-step explanation:
Pythagoras.
c² = a² + b²
the trigonometric functions in a norm circle (radius = 1) express the side lengths of inscribed right-angled triangles.
sin(x) is one side (e.g. "a") "touching" the 90 degree angle.
cos(x) is the other side ("b") of the 90 degree angle.
and the radius (1) is the Hypotenuse (the side opposite of the 90 degree angle), which is called "c" in the formula of Pythagoras.
so, we have
1² = (sqrt(13)/7)² + b²
b² = 1² - (sqrt(13/7)² = 1 - 13/49 = 49/49 - 13/49 = 36/49
b = cos(x) = sqrt(36/49) = 6/7
as we don't know anything about the angle x except that it has a positive sin(x) value, the cos(x) value can be positive or negative depending on if x is an angle of the first or of the second quadrant in the norm circle.
in the first quadrant cos(x) is also positive, in the second quadrant cos(x) is negative.
the third and fourth quadrants do not apply, as sin(x) would be negative for both.
The volume inside a rectangular storage room is 2,043 cubic feet. The room is 9 feet high. Find the area of the floor.

Answer:
227 square feet
Step-by-step explanation:
The volume of a rectangular prism is given by the formula ...
V = Bh
where B is the area of the base, and h is the height.
Filling in the given information, we have ...
2043 ft³ = B·(9 ft)
Dividing by the coefficient of B gives its value:
B = (2043 ft³)/(9 ft) = 227 ft²
The area of the floor is 227 square feet.

what is x in the equation 3x+4=2x+6?
Answer:
x= 2
Step-by-step explanation:
Answer:
3x + 4 = 2x + 6
3x +4 - 2x - 6 =0
x - 2 = 0
x = 2
3(2) +4 = 2(2) + 6
6 + 4 = 4 + 6
10 = 10
3x+2=2x+6
subtracting 2 from both sides
3x+2-2=2x+6-2
3x=2x+4
subtracting 2x from both sides
3x-2x=2x-2x+4
x=4
