Answer:
x - 3 > 15 ;
x > 18
Step-by-step explanation:
Given a number, x
3 less than x ; x - 3
3 less than x is more than 15
The inequality expression becomes ;
x - 3 > 15
We can solve for X ;
x - 3 > 15
Add 3 to both sides ;
x - 3 + 3 > 15 + 3
x > 18
What is the probability of rolling a 1 on a die or rolling an even number on a die? P(E)=P( rolling a 1) −P( rolling an even number) P(E)=P( rolling a 1) ×P( rolling an even number) P(E)=P( rolling a 1 )+P( rolling an even number) P(E)=P( rolling a 1) /P( rolling an even number) Saved In a binomial distribution, which R function would we use to calculate a value given the probability of the outcome being less than that value: qbinom() pbinom() dbinom() rbinom0 ( )
The probability of rolling a 1 on a die or rolling an even number on a die is 1/3. This is because the probability of rolling a 1 is 1/6, the probability of rolling an even number is 1/2
The probability of rolling a 1 on a die or rolling an even number on a die is P(E) = P(rolling a 1) + P(rolling an even number).
There are six possible outcomes of rolling a die: 1, 2, 3, 4, 5, or 6.
There are three even numbers: 2, 4, and 6. So, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.
The probability of rolling a 1 is 1/6.
Therefore, P(E) = 1/6 + 1/2 = 2/6 or 1/3.
The correct answer is P(E) = P(rolling a 1) + P(rolling an even number).
If we roll a die, then there are six possible outcomes, which are 1, 2, 3, 4, 5, and 6.
There are three even numbers, which are 2, 4, and 6, and there is only one odd number, which is 1.
Thus, the probability of rolling an even number is P(even) = 3/6 = 1/2, and the probability of rolling an odd number is P(odd) = 1/6.
The question asks for the probability of rolling a 1 or an even number. We can solve this problem by using the addition rule of probability, which states that the probability of A or B happening is the sum of the probabilities of A and B, minus the probability of both A and B happening.
We can write this as:
P(1 or even) = P(1) + P(even) - P(1 and even)
However, the probability of rolling a 1 and an even number at the same time is zero, because they are mutually exclusive events.
Therefore, P(1 and even) = 0, and we can simplify the equation as follows:P(1 or even) = P(1) + P(even) = 1/6 + 1/2 = 2/6 = 1/3
In conclusion, the probability of rolling a 1 on a die or rolling an even number on a die is 1/3. This is because the probability of rolling a 1 is 1/6, the probability of rolling an even number is 1/2, and the probability of rolling a 1 and an even number at the same time is 0. To solve this problem, we used the addition rule of probability and found that P(1 or even) = P(1) + P(even) - P(1 and even) = 1/6 + 1/2 - 0 = 1/3. Therefore, the answer is P(E) = P(rolling a 1) + P(rolling an even number).

Haley has 48 colored pencils and 3 cups (A, B, C). Cup A holds one more colored pencil than cup C. Cup B holds 2 more colored pencils than cup C. How many pencils does cup B contain?
Answer:
17 pencils
Step-by-step explanation:
Assume that cup C holds x pencils. In this case, cup A holds x + 1 pencils, and cup B holds x + 2 pencils. We know that all of the cups together hold 48 pencils. If we add what we got together, we would get x + x + 1 + x + 2 = 48. 2x + 1 + x + 2 = 48. 2x + x + 1 + 2 = 48. 3x + 1 + 2 = 48. 3x + 3 = 48. 3x = 48 - 3. 3x = 45. x = 45 / 3. x = 15. Now, we know that cup C holds 15 pencils, and from here, we can find the number of pencils in cup B by adding 2 to 15 and getting 17, and that would be your answer.

A textile production facility produces curtains which are sold in home design stores in their area. Their gross sales in hundreds of dollars, S, is dependent on the number of curtains they produce, x, and can be modeled by the functionS(x)=−20+2.5x.Draw the graph of the gross sales function by plotting its S-intercept and another point.
Plot the points (0, -20) and (10, 5) on a graph, and draw a line connecting them to represent the gross sales function S(x) = -20 + 2.5x.
To draw the graph of the gross sales function S(x) = -20 + 2.5x, we need to plot two points: the S-intercept and another point.
First, let's find the S-intercept. The S-intercept is the value of S when x = 0. Substituting x = 0 into the function, we get:
S(0) = -20 + 2.5(0) = -20
So the S-intercept is -20, which means that when the production facility produces 0 curtains, they will not make any sales.
Now, let's find another point. We can choose any value of x and calculate the corresponding value of S. Let's choose x = 8 (you can choose any other value if you prefer). Substituting x = 8 into the function, we get:
S(8) = -20 + 2.5(8) = 0
So when the production facility produces 8 curtains, their gross sales will be $0. This means that the break-even point is at x = 8, where the revenue from selling the curtains covers the production costs.
To plot the graph, we can use these two points: the S-intercept (-20, 0) and the point (8, 0). The graph should look like this:
```
|
|
|
| *
| *
| *
|*_______
0 8 x-axis
S-axis
```
The x-axis represents the number of curtains produced, and the S-axis represents the gross sales in hundreds of dollars. The graph shows that the gross sales function is a linear function that increases as the number of curtains produced increases. The break-even point is at x = 8, and after that, the production facility starts making a profit.

If a couple has three children, let x represent the number of girls. What is the probability that the couple does not have girls for all three children?
Assuming an equal probability of having a girl or a boy for each child, the probability that a couple does not have girls for all three children is 1/8 or approximately 0.125 (12.5%).
If we assume that the probability of having a girl or a boy for each child is equal (which is a simplifying assumption), then the probability of having a girl for each child is 1/2, and the probability of having a boy is also 1/2.
To find the probability that the couple does not have girls for all three children, we need to find the probability of having a boy for each child. Since the gender of each child is independent of the others, we can multiply the probabilities together.
So, the probability of having a boy for the first child is 1/2, for the second child is also 1/2, and for the third child is also 1/2.
Multiplying these probabilities together, we get:
(1/2) * (1/2) * (1/2) = 1/8
Therefore, the probability that the couple does not have girls for all three children is 1/8 or approximately 0.125 (12.5%).

Proof that f is a well-defined function from O to 2Z: Given any odd integer n, by definition of odd, there exists an integer, say k, such that n
the function f is well-defined from O (the set of odd integers) to 2Z (the set of even integers), we need to show that for every odd integer n in O, there exists a unique even integer f(n) in 2Z.
Given any odd integer n, by definition, there exists an integer k such that n = 2k + 1.
Now, let's define f(n) = 2k.
To show that f(n) is well-defined, we need to demonstrate two things:
1. f(n) is even: Since f(n) = 2k, it is a multiple of 2 and therefore an even integer.
2. f(n) is unique: Suppose there is another even integer m in 2Z such that m = 2k'. We need to show that
k = k'.
Since n = 2k + 1 and m = 2k', we have 2k + 1 = 2k'.
Rearranging the equation, we get 2k - 2k' = -1, which implies k - k' = -1/2. But this contradicts the assumption that k and k' are integers, so k = k' and f(n) is unique.
Hence, we have shown that f(n) = 2k is a well-defined function from O to 2Z, as it assigns a unique even integer to every odd integer.

ABOVE & BEYOND John's school is selling tickets to a spring musical. On the first day of ticket sales, the school sold 8 adult tickets and 5 child tickets for a total of $104. The school took in $80 on the second day by selling 4 adult tickets and 6 child tickets. On the third day, they sold 10 adult tickets and 4 child tickets. On the last day, they sold 22 adult tickets and 8 child tickets. How much more money did they make on the last day compared to the third day? UNIT
"The school sold 8 adult tickets and 5 child tickets for a total of $104", we can express it as follows
\(8x+5y=104\)"On the second day they sold 4 adult tickets and 6 child tickets for a total of $80", we can express it as follows
\(4x+6y=80\)These two equations form a linear system of equations, which we can solve by multiply the second equation by -2
\(\begin{cases}8x+5y=104 \\ -8x-12y=-160\end{cases}\)Then, we combine the equations
\(\begin{gathered} 8x-8x+5y-12y=104-160 \\ -7y=-56 \\ y=\frac{-56}{-7} \\ y=8 \end{gathered}\)Now, we find x
\(\begin{gathered} 8x+5y=104 \\ 8x+5\cdot8=104 \\ 8x=104-40 \\ x=\frac{64}{8} \\ x=8 \end{gathered}\)According to this solution, each adult ticket costs $8 and each child ticket costs $8.
If they sold 10 adult tickets and 4 child tickets on the third day, then they made
\(10\cdot8+4\cdot8=80+32=112\)If they sold 22 adult tickets and 8 child tickets on the last day, then they made
\(22\cdot8+8\cdot8=176+64=240\)Hence, they made $128 more on the last day than the third day because that's the difference.The national percentage of automobile accident fatalities that are alcohol related is 39%. In a random sample of 96 automobile accident fatalities in the state of Connecticut, 44 were alcohol related. Is this sufficient evidence to say that Connecticut has a higher percentage of alcohol related automobile fatalities?
Answer:
Step-by-step explanation:
Given that:
There are 96 automobile accident fatalities in Connecticut and 44 were alcohol related.
The null hypothesis and the alternative hypothesis for this study can be computed as:
\(H_o: P =0.39 \\ \\ H_1:P> 0.39\)
The sample proportion \(\hat p\)= 44/96 = 0.45833
Using the Z formula for a single proportion test, we get;
\(Z = \dfrac{\hat p - P }{\sqrt\dfrac{{P(1-P)}}{{n}}}\)
\(Z = \dfrac{0.45833 - 0.39 }{\sqrt\dfrac{{0.39(1-0.39)}}{{96}}}\)
\(Z = \dfrac{0.06833 }{\sqrt\dfrac{{0.39(0.61)}}{{96}}}\)
\(Z =1.37\)
The p-value = 1 -P(Z< 1.37)
The p-value = 1 - 0.9147
The p-value = 0.0853
At the level of significance (∝) 0.05 ;
Since p-value is greater than level of significance (∝); we accept the null hypothesis and conclude that there is no sufficient evidence to say that higher percentage of alcohol is related to automobile fatalities.

How to calculate the valueStarting with -71uv^2u, we can simplify this by multiplying the coefficients together to get -71u^2v^2.
Moving on to (3vu^2v - 5u^6u^2v^4), we can simplify this by combining like terms. First, let's simplify u^6u^2 to u^8:
3vu^2v - 5u^8v^4
Now, we have two terms that contain the variable v, so we can combine them by adding their coefficients:
-5u^8v^4 + 3vu^2v = -5u^8v^4 + 3u^2v^2
Finally, we add this result to the last term, 3u^3v^2v^2u^5, which does not have any like terms to combine:
-5u^8v^4 + 3u^2v^2 + 3u^3v^2v^2u^5
Simplifying further, we can factor out a common factor of u^2v^2:
u^2v^2(-5u^6 + 3 + 3u^3v^2)
