b. What is the probability that you don’t roll a 2 or a 3, P (NOT a 2 or 3)? Explain your reasoning. (2 points possible)
1. In a game, if you roll a 2 or a 3 on a 6-sided number cube, you lose a turn. NOTE: This is just using one number cube.
Answers
Answer:
The probability that you don’t roll a 2 or a 3 = 2/3
Step-by-step explanation:
Formula for Probability = Number of Possible Outcomes / Number of events
We are told in the question that it is just a one number cube. This means that :
We have the Probability of rolling the 6 sided cube and obtaining, 1, 2, 3, 4, 5, and 6.
We are told in the question to find the probability of not rolling a 2 or 3.
Hence, this means
Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6).
Therefore,
Probability (of rolling a 1) = 1/6
Probability (of rolling a 4) = 1/6
Probability (of rolling a 5) = 1/6
Probability (of rolling a 6) = 1/6
Therefore, Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6) = P(1) + P(4) + P(5) + P(6)
= 1/6 +1/6 + 1/6 + 1/6
= 4/6
= 2/3.
Therefore, the probability that you did not roll a 2 or 3 ( i.e P( not 2 or 3)) = 2/3

Choose the fraction that is equal to 0.245 A. 49/10 B. 245/999 C. 245/900 D. 245/1000
Answers
Final answer:
The correct fraction equal to the decimal 0.245 is 245/1000, which is option D in the given choices. This is determined by looking at the place value of the decimal and converting it into a fraction by placing the number over the corresponding power of ten.
Explanation:
To choose the fraction equal to 0.245, we need to convert the decimal to a fraction. To do this, we look at the place value of the farthest digit to the right in the decimal, which is in the thousandths place, since 0.245 can be written as 245 thousandths. Thus, the fraction is 245 over 1000, which simplifies to 245/1000.
Looking at the given options, we can see that option D is 245/1000, which is equivalent to the decimal 0.245. Therefore, the correct answer is D. Additionally, if we were to divide 1.9436 by 1000 as in your provided example for converting decimals and fractions, we would have 0.0019436. Similarly, to change the decimal 0.0479 to a number from 1 to 10, we move the decimal point two places to the right, obtaining 4.79, which shows an understanding of decimal and fraction conversion.

Answers
Answer:
8.8 hours
Step-by-step explanation:
Happy paws cost equation
5.50h + 20
Wood watchers cost equation
6.75h + 9
Make the two equations equal
5.50h+20 = 6.75h+ 9
Collect the co-efficient of both sides.
6.75h- 5.50h= 20-9
1.25h= 11
Divide both sides by the coefficient of h
1.25h/1.25= 11/1.25
h= 8.8
Answer:
8.8 hours
Equation :20+5.50h = 9 + 6.75 h
Step-by-step explanation:
Hi, to answer this question we have to write a Cost equation for each case:
For Happy Paws the cost will be equal to the fixed cost (20) plus the product of the cost per hour (5.50) and the number of hours (h).
Happy paws cost: 20+5.50 h
Same process for Woof Watchers:
Woof Watchers cost = 9 + 6.75 h
If both costs are equal:
Happy paws cost=Woof Watchers cost
So:
20+5.50h = 9 + 6.75 h
Solving for h
20-9 = 6.75h-5.50h
11 = 1.25h
11/ 1.25 =h
8.8 = h

Answers
Final answer:
To solve the system of equations, use the method of substitution. Solve one equation for one variable and substitute the value in the other equation. Simplify and solve for the variable, then find the value of the other variable. The solution to the system is x = 7 and y = 2.
Explanation:
To determine the solution to the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.
Step 1: Solve one equation for one variable
From the first equation, we can isolate x: x = 1 + 3y
Step 2: Substitute the value of the variable in the other equation
Substitute x = 1 + 3y into the second equation: 3(1 + 3y) - 5y = 11
Step 3: Simplify and solve for y
Expand the equation and simplify: 3 + 9y - 5y = 11
Combine like terms: 9y - 5y = 11 - 3
Simplify: 4y = 8
Solve for y: y = 2
Step 4: Find the value of the other variable
Substitute the value of y into the first equation: x - 3(2) = 1
Simplify and solve for x: x - 6 = 1
x = 7
Therefore, the solution to the system of equations is x = 7 and y = 2.

The graph of f "(x) is continuous and decreasing with an x-intercept at x = 0. Which of the following statements is true?

The graph of f has a relative minimum at x = 0.
The graph of f has an inflection point at x = 0.
The graph of f has an x-intercept at x = 0.
Thank you in advance!
Answers
Answer:
The graph of f has an inflection point at x = 0.
Step-by-step explanation:
An inflection point occurs when the second derivative changes signs. Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.
The statements "The graph of f has an inflection point at x = 0." is true
X-interceptThe meaning of X-INTERCEPT is the x-coordinate of a point where a line, curve, or surface intersects the x-axis.
How to solve this problem?F''(x) tells you whether the function is concave up, down, or where it's inflection points are.F"(x)>0 tells you it's concave up.F"(x)<0 tells you it's concave down.F"(x)=0 tells you there's a possible point of inflection at xSince this function is continuous and decreasing, we can assume that before it intercepts x at 0, it is concave up and after it intercepts, it continues to decrease which makes it concave down. Since F"(x)=0 & there is a change in sign, the statement 'The graph of f has an inflection point at x = 0." is true.From above reasons we can say that the statement "The graph of f has an x-intercept at x = 0." is true

No, x = 0 is not a valid solution for log(x + 7) + log(x − 3) = 17 .
Given,
log(x + 7) + log(x − 3) = 17
Here,
Substitute the value of x in the equation,
log(7) + log(-3) = 17
So,
log(-3) is not a valid number and thus its value does not exist .
Thus the equation can not be equated to 17 .
Hence option B is correct .

A spinner has five equal sectors colored red, yellow, green, blue, orange. What is the
probability of landing on a yellow first and then on a blue sector after two consecutive
spins?
Answers
Answer: 5/25
5/50
Step-by-step explanation: If each part has 5 sections then it equals to 25 so you have a 5 out of 25 chance of getting it, The second time I added 25 twice since it says your spinning it twice, but you still only have 5 sections so you would have 5 out of 50
The calculated probability is 4 percent.
The student's question involves calculating the probability of two independent events occurring in sequence. Since each sector on the spinner is equal, the probability of landing on yellow for the first spin is 1 out of 5 or 0.2. Similarly, the probability of landing on blue for the second spin is also 1 out of 5 or 0.2.
Since these are independent events, their probabilities are multiplied to find the combined probability. Therefore, the probability of landing on yellow first and then on blue for the second spin is 0.2 * 0.2 = 0.04. This means there is a 4 percent chance of this outcome occurring.
SAT verbal scores are normally
distributed with a mean of 450
and a standard deviation of 120.
Determine what percent of the
scores lie between 450 and 570.
Answers
Answer:
The percentage of the scores lying between 450 and 750 is 49.4%
Step-by-step explanation:
In this question, we are simply asked to calculate the percentage of the scores lying between a particular range.
The first thing to do here is to calculate the z score of both scores
Mathematically, z score = (x - mean)/SD
for score 450, we have ; z = (450-450)/120 = 0/120 = 0
For score 750, we have z = (750-450)/120 =
2.5
Now, we move on to calculate the probability before turning it into a percentage.
The supposed probability we are to calculate is as follows;
P(450 < x < 750) or P(0 < z < 2.5)
Using standard score table, P = 0.49379
The percentage is thus 49.4%

Tom saves 35% of his salary . Jerry spends 3/5 of his salary and saves rthe rest of his salary work out who saves the most money each month you must show your working.
Answers
Final answer:
Jerry saves more money each month than Tom. Tom saves 35% of his salary, whereas Jerry spends 3/5 and saves the remainder, which is 2/5 of his salary. Assuming equal salaries, Jerry's savings are greater.
Explanation:
The question is asking us to compare how much Tom and Jerry save from their salaries. Let's assume each of them earns the same amount of salary, say for example $1000 (this figure is just for simplicity and can represent any currency or amount).
Tom saves 35% of his $1000 salary, which is 0.35 * $1000 = $350.
Jerry spends 3/5 of his salary, which is 3/5 * $1000 = $600. Therefore, he saves 2/5 of his salary because 1 - 3/5 = 2/5. So Jerry saves 2/5 * $1000 = $400.
Comparing the two, Jerry saves more each month since $400 (Jerry's savings) is greater than $350 (Tom's savings).
