Final answer:
The probability that Ichiro has Art on Friday, given that he has already had Library on Monday and the subjects are assigned randomly, is 1/6 or approximately 16.67%.
Explanation:
The subject of this question is Probability. Ichiro has Library on Monday, and since he cannot have the same special subject more than once in a week, there are six subjects left to schedule from Tuesday to Friday. The special subjects are considered to be assigned randomly.
To determine the probability that Ichiro has Art on Friday, we need to consider there are four days left in the school week (Tuesday to Friday) after Monday. Since the subjects are assigned randomly, each of the remaining subjects has an equal chance of being assigned to any day. By the time we get to Friday, there will be only one subject left unassigned, which has a 1 out of 6 chance of being Art, as the remaining subjects are randomly assigned to the days preceding.
The probability that Ichiro has Art on Friday is therefore 1/6, or approximately 16.67%

Answer:
1296
Step-by-step explanation:
Note there is a common ratio between consecutive terms of y, that is
36 ÷ 6 = 216 ÷ 36 = 6
Thus to find a term, multiply the previous term by 6
216 × 6 = 1296
The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of $5560
Answer:
No units
Step-by-step explanation:
The cost function is given by;
[tex]C(x)=x^2-20x+35[/tex]
To find the units manufactured at a cost of $5,560
We equate the C(x) to 5560 and solve for x.
[tex]x^2-20x+35 = 5560[/tex]
[tex]x^2-20x+35 - 5560 = 0[/tex]
[tex]x^2-20x - 5525= 0[/tex]
The discriminant of this equation is negative.
That is,
[tex]d = {( - 20)}^{2} - 4 \times 1 \times - 5560 \: < 0[/tex]
Hence the equation has no real roots.
This means no units can be produced at $5,560

3. Which table is an example of exponential growth? (SEE PICTURE)
a. fun island
b. Great island
c. mystery island
4. How can you determine if a table is a linear function or an exponential function?
1.
Answer: D) rapid spread of diseaseChoice A is not exponential growth or decay because the cost will go up by the same amount ($2) each time. Choices B and C are exponential, but they aren't growth functions. Rather, they are decay functions. A disease spreads exponentially because one person infects two, and then each of those two people infect two others (making 4 additional people infected), and so on.
===============================
2.
Answer: C) number of cancer cells over time with treatmentAssuming the treatment works and it is effective, then the cancer cells will go away over time. One example would be that the population is cut in half each time. Choice A is not an answer because the balance will go down the same amount each time. This is assuming the bus company does not change its prices. Choices B and D are eliminated because they represent growth.
================================
3.
I'm unable to answer this because the table is missing.
================================
4.
If the y values increase or decrease by the same amount, as x increases by some set amount, then you have a linear function. For example, if x increases by 1 pairs up with y increasing by 4, then the slope is 4/1 = 4 and we have a linear function.
--------
On the other hand, if x increases by 1 couples with the y values multiplying by some set amount, then you have an exponential function.
Example:
(x,y) = (1,2)(x,y) = (2,10)(x,y) = (3,50)Each time x increases by 1, y is multiplied by 5.

3) Radius of shaded circle=1.5 units
Area of shaded circle=pi*1.5^2=2.25*pi=7.0686
Area of big circle=pi*5^2=25pi=78.54
Divide the two together: 7.0686/78.54=0.09 so exactly 9% is the probability
4) Area of whole rectangle: 8*5=40
Area of unshaded region: (2*3)+(2*2)/2=6+4/2=6+2=8
40/8=5, so there's a 5 to 1 chance.

Answer:
68.5
Step-by-step explanation:
Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:
∠ACE = 180° -43° = 137°
Inscribed angle ABE has half the measure of central angle ACE, so we have ...
x° = 137°/2
x = 68.5
Kara rolled a number cube 10 times. The results of her rolls are shown
below.
1, 3, 3, 4, 6, 2, 2, 5, 3, 4
Based on Kara's results, what is the probability that her next roll
is either a 3 or 6?
Final answer:
The probability that Kara's next roll is either a 3 or a 6 is 1/3.
Explanation:
The question asks about the probability of rolling either a 3 or a 6 on a six-sided die based on previous rolls. The previous rolls are as follows: 1, 3, 3, 4, 6, 2, 2, 5, 3, 4. It is important to understand that each roll of a die is an independent event, meaning the outcome of one roll does not affect the outcomes of any other rolls.
Therefore, the results of Kara's previous rolls do not impact the probability of future rolls.
To determine the probability of rolling either a 3 or a 6, we consider that a six-sided die has six equally likely outcomes.
The probability of rolling a specific number, like a 3 or a 6, is therefore 1/6.
Since these are two separate outcomes, we add their individual probabilities to determine the probability of rolling either a 3 or a 6:
Probability of rolling a 3 = 1/6
Probability of rolling a 6 = 1/6
Total probability of either a 3 or 6 = 1/6 + 1/6 = 2/6 or 1/3.
Thus, the probability that Kara's next roll is either a 3 or a 6 is 1/3.

A semi-circle with a diameter of 4 is rotated around its diameter one full rotation, what is the volume of the solid generated by the revolution?
The volume of the solid generated by the revolution is 33.5 cubic units.
Step-by-step explanation:
It is given that, the diameter of the semi-circle is 4 and it is rotated to one full rotation around its diameter.
A solid generated when a semicircle is being rotated about its diameter is called a "SPHERE".
Therefore, the volume of the solid generated by the revolution is the volume of the sphere.
The formula for volume of the sphere is given by,
Volume of sphere = (4/3)πr³
where, r is the radius and π has the default value of 3.14
Here, the given diameter is 4.
To find the radius = diameter/2
radius = 4/2 = 2.
Now, to calculate volume of sphere substitute r=2 and π=3.14
volume of the sphere = (4/3)×3.14×2³
⇒ (4/3)×3.14×8
⇒ 100.48 / 3
⇒ 33.49 (approximately 33.5)
Therefore, the volume of the solid generated by the revolution is 33.5 cubic units.

3, 4, 1, 4, 1, 1, 2, 1
Answer:
The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5
Step-by-step explanation:
The topic in question is Experimental probability;
Experimental probabilities deal with the probability of an event happening based on past experiments.
Given
Number of observation, n = 8
To calculate an estimate of the probability that the Texas Sharpshooters score exactly 1 goal next hockey game, we need to count the total occurrence of 1 in the given data
Let p = total occurrence of 1
p = 4
The probability is then calculated as [tex]\frac{p}{n}[/tex]
by substitution;
Probability = [tex]\frac{4}{8}[/tex]
Probability = 0.5
Hence, The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5

The powers of 2 that are in the range 2 through 1,000 are 2, 4, 8, 16, 32, 64, 128, 256, and 512. Find all the powers of 3 that are in the range 3 through 1,000.
Final answer:
The powers of 3 that fall within the range of 3 through 1,000 are 3, 9, 27, 81, 243, and 729.
Explanation:
To find all the powers of 3 that are in the range 3 through 1,000, we need to calculate successive powers of 3 until the result exceeds 1,000. These calculations give us 31=3, 32=9, 33=27, 34=81, 35=243, 36=729, and 37=2187. However, since 2187 is greater than 1,000, we exclude it from our list. Therefore, the powers of 3 that fall within the specified range are 3, 9, 27, 81, 243, and 729.

13. Your business needs to ship a package to another store. Company A charges $2.50 per pound plus a
$20 service charge. Company B charges $4.50 per pound without any service charge.
a. At what weight does it cost the same for both companies?
Solution:
Let "x" be the pounds
Company A charges $2.50 per pound plus a $20 service charge
Cost : 2.50x + 20 ------ eqn 1
Company B charges $4.50 per pound without any service charge
Cost : 4.50x ------- eqn 2
At what weight does it cost the same for both companies?
For both companies to cost the same, eqn 1 must be equal to eqn 2
2.50x + 20 = 4.50x
4.50x - 2.50x = 20
2x = 20
Divide both sides by 2
x = 10
Thus for 10 pounds, both companies cost the same
Solve the following equation 3+3x+9(9x)
I believe that the answer is 3+84x is this question wants you to simplify the expression.
Answer:
84x + 3
Step-by-step explanation:
3+3x+9(9x)
First 9 times 9x, which equals 81x
Then add the variables, so 3x + 81x and you get 84x
The equation is left as 84x + 3 because you can't add together a number with a variable and a number without a variable

The figure is the net for a rectangular prism.
What is the surface area of the rectangular prism represented by the net?
Surface area of rectangular prism is [tex]238\ mm^{2}[/tex] .
Step-by-step explanation:
We have net for a rectangular prism. Surface area of rectangular prism is given by:
Step 1:
We need to calculate area of material needed as shown in figure above, Let's first concentrate on vertical rectangle have width 11 mm and length ( 5 + 4 + 5 +4 ) mm = 18 mm. We know that ,
area of rectangle = length × width
⇒ [tex]area = length(width)\\area = 11(18)\\area = 198\ mm^{2}[/tex]
Step 2:
Now only two horizontal small rectangles are left with dimensions as length = 4 mm and width = 5 mm.
∴ area of rectangle = length × width
⇒ [tex]area = length(width)\\area = 4(5)\\area = 20\ mm^{2}[/tex]
Also there are Two rectangles , so
total area = [tex]2(area) = 2(20) = 40\ mm^{2}[/tex]
Step 3:
Adding area of step 1 and 2 we get : [tex]198\ mm^{2} + 40\ mm^{2} = 238\ mm^{2}[/tex]
∴ Surface area of rectangular prism is [tex]238\ mm^{2}[/tex].

What is the answer for -3 -4m = -7(-4m+4)-7m
1. Expand
- 3 - 4m = 28m - 28 - 7m
2. Simplify 28m - 28 - 7m to 21m - 28
- 3 - 4m = 21m - 28
3. Add 4m to both sides
- 3 = 21m - 28 + 4m
4. Simplify 21m - 28 + 4m to 25m - 28
-3 = 25m - 28
5. Add 28 to both sides
- 3 + 28 = 25m

Using the following diagram, tick the correct angles which are congruent to the angles given in the first column. (first answer most brainliest.)
Angle 1 is congruent to angles 3, 5, and 7. We know this because vertical angles are congruent (angle 3), as are corresponding angles (angle 5) and alternate exterior angles (angle 7).
Angle 3 is congruent to angles 1, 5, and 7. We know this because vertical angles are congruent (angle 1), as are corresponding angles (angle 7) and alternate interior angles (angle 5).
Angle 4 is congruent to angles 2, 6, and 8. We know this because vertical angles are congruent (angle 2), as are corresponding angles (angle 8) and alternate interior angles (angle 6).
Angle comparison requires measuring each angle with a protractor. Angles are congruent if their measurements are equal. This concept is used in geometry and other fields like physics.
Explanation:Your question involves identifying and comparing angles, which is a topic in geometry, a branch of mathematics. When determining congruent angles, you need to look at the measure of the angles. Two angles are congruent if they have the exact same measure.
In the problem you provided, to find the congruent pairs, you would have to measure each angle provided with a protractor. If the measure of the angles is equal, then those angles are congruent.
Remember that in a right triangle, the angles are 90 degrees, 45 degrees and 45 degrees. The angles of a straight line sum up to 180 degrees. These are valuable skills which you can use to aspects of physics, specifically when dealing with vectors as you mentioned tail-to-head addition of vectors and the angles between them.
