Question 6 of 10
Which equation matches the graph of the greatest integer function given
below?
Answer:
B. y = [x] + 3
Step-by-step explanation:
The answer to this graph would be
B. y = [x] + 3
This is because the graph is translated up by 3 units. Such that a value of 0 passed into x would give us a y value of 3 on the graph, which is represented as a black dot. For a value of -4 passed as x, the largest integer that is less than -4 would be -4 itself and if we add 3 to it due to following this function, we get a y value of -1 which is what is represented in the graph.
What is the probability of drawing two yellow marbles if the first one is NOT placed back into the bag before the second draw?
Answer:
2/10 on the first draw and 1/9 on the second draw
Step-by-step explanation:
In the first draw, 2 marbles are yellow out of 10, but on the second draw, you don't replace a yellow marble leaving 1 yellow marble out of 9 total marbles in the bag.
figure out by using substitution
5x + 2 y = 7
4x + y = 8
Answer:
(3, - 4 )
Step-by-step explanation:
Given the 2 equations
5x + 2y = 7 → (1)
4x + y = 8 → (2)
Rearrange (2) expressing y in terms of x by subtracting 4x from both sides
y = 8 - 4x → (3)
Substitute y = 8 - 4x into (1)
5x + 2(8 - 4x) = 7 ← distribute and simplify left side
5x + 16 - 8x = 7
16 - 3x = 7 ( subtract 16 from both sides )
- 3x = - 9 ( divide both sides by - 3 )
x = 3
Substitute x = 3 into (3) for corresponding value of y
y = 8 - 4(3) = 8 - 12 = - 4
solution is (3, - 4 )

1. If you toss a coin 30 times, you expect the coin lands on the tail _____ times.
Answer:
15 times
Step-by-step explanation:
50% of the time, 50% of 30=15
Answer: 15 times
Step-by-step explanation:
A coin has a 50/50 chance to get either heads or tails. 50% of the time it's heads, 50% is tails. So, if you tossed a coin 30 times, you would expect the coin to land on the tail 15 times because 30 / 2 = 15.

A flock of sheep has 182 white sheep and 98 spotted sheep. Which proportion can be used to determine p, the percent of the flock that has spots?
Answer:
D) 98/280 = p/100
Step-by-step explanation:
Since p is the missing percentage, it has to be OVER 100, so C is eliminated.
Total:
182 + 98 = 280
Spotted sheep probability:
98/280 = 0.35 or 35%
To check:
[tex]\frac{98}{280} =\frac{p}{100} \\\\280p=9800\\x=35[/tex]

Step-by-step explanation:
If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?
Answer:
12 students
Step-by-step explanation:
Here is the complete question
Alex surveyed 60 students about their favorite zoo animals and made the circle graph of the results shown below. A circle graph titled Favorite Zoo Animals is shown. There are five sections. One section is labeled Bears, one section is labled Lions, one section is labeled Monkeys, one section is labeled Elephants, and one section is labeled Giraffes.
If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?
Number of students that said the giraffe was their favorite zoo animal = (angle measuring the section for giraffes / sum of angles in a circle graph) x number of students surveyed
the sum of angles in a circle = 360 degrees
(72 / 360) x 60 = 12 students
If the circle has a diameter of a team meters in a central angle of 210° what is the area of the sector
Answer:
[tex]Area = 45.82m^2[/tex]
Step-by-step explanation:
Given
[tex]d = 10m[/tex] --- diameter
[tex]\theta = 210^\circ[/tex]
Required
Determine the area of the sector
The ares of the sector is calculated as:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
Where
[tex]r = \frac{d}{2}[/tex]
This gives:
[tex]r = \frac{10m}{2} = 5m[/tex]
So, we have:
[tex]Area = \frac{210}{360} * 3.142 * 5^2[/tex]
[tex]Area = \frac{210}{360} * 78.55[/tex]
[tex]Area = \frac{210 * 78.55}{360}[/tex]
[tex]Area = \frac{16495.5}{360}[/tex]
[tex]Area = 45.82m^2[/tex]

y = f(x). What is the rate of change of
f(x) with respect to x?
Answer:
The rate of change of f(x) with respect to x is 1/4
Step-by-step explanation:
What this question simply ask is to find the slope of the line that passes through the two points
to find this, we use the slope equation
we have this as;
m= (y2-y1)/(x2-x1)
(x1,y1) = ((-15,-3)
(x2,y2) = (-7,-1)
m = (-1 + 3)/(-7 + 15) = 2/8 = 1/4

Answer:
Elena's sales and expenses will both be $0 if she sells 36 boxes of cards.
Step-by-step explanation:
Elena paid a flat fee of $54 as well as $9.50 for each box. She sells each box of cards for $11. Set the equation. Let the amount of box be signified by the variable, x.
9.50x + 54 = 11x
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9.50x from both sides of the equation:
9.50x (-9.50x) + 54 = 11x (-9.50x)
54 = 11x - 9.50x
54 = 1.50x
Next, divide 1.50 from both sides of the equation:
(54)/1.50 = (1.50x)/1.50
x = 54/1.50
x = 36
36 boxes is your answer, and the sales and expense will be $0. She breaks even.
~
Answer:
YOUR ANSWER: Elena's sales and expenses will both be $396 if she sells 36 boxes of cards.
Step-by-step explanation:
Hi,
To begin, you have to write two separate equations to represent both, how much she spends, and how much she gets after selling her box of cards.
We know that she pays $9.50 for materials per box. We also know she pays $54 for her booth. We can write the equation...
y = 9.5x + 54
Now, to get the equation for how much she gets, we know that she sells each box of cards for $11. We can simply write...
y = 11x
Now, this is a system of equations. All we have to do is solve.
We know that y = 11x. We can plug it into the first equation like this...
11x = 9.5x + 54
Now, isolate the variable, x.
Subtract 9.5x on both sides...
1.5x = 54
Divide by 1.5 on both sides...
x = 36
Now, plug in 36 in both equations to get the value she has after selling 36 boxes.
In the first one...
y = 9.5 (36) + 54
y = 396
Now, the second one... (if we're right, it also has to equal 396)
y = 11 (36)
y = 396
That means we're correct.
YOUR ANSWER: Elena's sales and expenses will both be $396 if she sells 36 boxes of cards.
I hope this helps, let me know if you need anything else :)
Find an exponential equation that passes through the points (0, 4) and (2, 9).
Given:
An exponential equation passes through the points (0,4) and (2,9).
To find:
Exponential equation that passes through the given points.
Solution:
Let the required exponential function is:
[tex]y=ab^x[/tex] ...(i)
The function passes through the points (0,4) and (2,9). It means the above equation must be true for these points.
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
And,
[tex]9=ab^2[/tex]
Substituting [tex]a=4[/tex], we get
[tex]9=(4)b^2[/tex]
[tex]\dfrac{9}{4}=b^2[/tex]
[tex]\pm \sqrt{\dfrac{9}{4}}=b[/tex]
[tex]\pm \dfrac{3}{2}=b[/tex]
In an exponential function b>0. So, [tex]b=\dfrac{3}{2}[/tex].
Putting [tex]a=4,b=\dfrac{3}{2}[/tex] in (i), we get
[tex]y=4\left(\dfrac{3}{2}\right)^x[/tex]
Therefore, the required exponential function is [tex]y=4\left(\dfrac{3}{2}\right)^x[/tex].
