Tom is throwing darts at a target. In his last 30 throws, Tom has hit the target 20 times. You want to know the estimated probability that exactly one out of the next three throws does not hit the target.
Categorize the simulations as correct or incorrect simulations of Tom’s scenario.
Answers
Each scenario can be used to simulate probability, and there are 3 correct scenarios and 2 incorrect scenarios in the list of options
How to categorize the simulations?From the question, we have the following parameters:
Number of throws = 30Number of hits = 20This means that the probability of hit is:
P(Hit) = 20/30
Simplify
P(Hit) = 2/3
Using the complement rule,
P(Miss) = 1/3
The above means that the simulation that represents the situation must have the following parameters:
P(Success) = 2/3P(Failure) = 1/3Number of experiments = 3Using the above highlights, the correct scenarios are:
Rolling a die three times with numbers 1 to 4 representing a hitSpinner a spinner of 3 equal sections three times with two sections representing hitSpinner a spinner of 6 equal sections three times with four sections representing hitRead more about probability at:

Answers
Answer:
except when x = 3
Step-by-step explanation:
f(x) = [tex]\frac{1}{x-3}[/tex]
the denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be.
x - 3 = 0 ⇒ x = 3 ← excluded value

What is the percent of change from 60 to 87?
Answers
Answer:
45% increase
Step-by-step explanation:
The new number (87) is bigger than the original number (60), so this is a percent increase.
To find the percent of change, which in this case is a percent increase, take the change amount and divide by the original, then convert to a percent.
Subtract to find the change.
87 - 60 is 27.
27 is the amount of change.
change/original
= 27/60
= .45
Times by 100 to change to a percent.
.45 × 100
= 45%

Artaud noticed that if he takes the opposite of his age and adds 39 he gets the number 24. How old is Artaud?
Answers
Answer:
15
Step-by-step explanation:
Let 'a' represent Artaud's age. He notices the relationship ...
-a +39 = 24
If we add a-24 to both sides, we get ...
15 = a
Artaud is 15 years old.
Answer: 15 years old
Step-by-step explanation:
Let x be Artaud's age. Let the opposite of his age be -x
-x + 39 = 24
-x = 24-39
-x = -15 (multiply both sides by -1)
x = 15 years old

Line q passes through points (9,10) and (5,1), Line r is parallel to line q, What is the slope.
Answers
Answer:
slope = 9/4
Step-by-step explanation:
Slope is a ratio (looks like a fraction) It tells you the steepness or flatness of a line.
To find slope you subtract the y's (that's the second number in the ordered pairs; here it's 10 and 1) put that on top. Then subtract the x's and put that on the bottom (here 9 and 5)
Slope = 10-1 / 9-5
=9/4
Now, parallel lines have the same slope, so if one of the lines has slope 9/4, then the other line does too!

There are 9 positive integers x satisfy the inequality x² + x < 100.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the inequality
x² + x < 100.
First take x= 1 then
1² + 1 = 2 < 100
Take x= 2
2² + 2 = 6 <100
Take x= 3
3² + 3 = 12 < 100
Take x = 4
4² + 4 = 20 < 100
Take x= 5
5² + 5 = 30 < 100
Take x =6, 7, 8, 9, 10 and 11
6² + 6<100
7² + 7<100
8² + 8<100
9² + 9 <100
10² + 10 > 100
So, there are 9 possible digits.

measure of angle ECD
Answers
Answer:
∠ECD = 82°
Step-by-step explanation:
Alternate Interior Angles Theorem : when two parallel lines are cut by a transversal, the alternate interior angles are congruent. Alternate angles form a Z shape and are sometimes called "Z angles".
Therefore,
∠CDF = ∠GBC = 45°
∠CEF = ∠GAC = 53°
The sum of the interior angles of a triangle is 180°
⇒ ∠ECD + ∠CDF + ∠CEF = 180
⇒ ∠ECD + 45 + 53 = 180
⇒ ∠ECD = 180 - 45 - 53 = 82°
In ∆ABC
m<C be x[tex]\\ \tt\longrightarrow x+53+45=180[/tex]

35.93
Step-by-step explanation:
If the mean of 15 numbers is 41.6, the sum of these numbers must be (15)*(41.6) = 624
We n=know one of these numbers is the 117 that was entered by mistake. Subtract that out and replace it with the correct number, 17. In essence we are modifying the number by (-117+17) or -100.
524 is the corrected value. Divide that by 15 to find the ciorrect mean:

By using the equivalence of the formed angles, the solution is x = 41.
How to get X?
Note that the angle that is at the right of the equation with x, is equivalent to the bottom right angle, which measures 60°.
Then we will have that:
(3x - 3)° + 60° = 180°
Now we can solve that for x:
(3x - 3)° = 180° - 60° = 120°
3x = 120 + 3
x = 123/3 = 41
The solution is x = 41
