A speaker is in the shape of a cube with an edge length of 3. 5 inches. The speaker is sold in a package in the shape of a square prism with a base area of 16 square inches and a height of 4. 25 inches.
What is the surface area of the package, in square inches? (number ONLY in the answer, DO NOT ROUND)
Answer: 100 inches
Step-by-step explanation: To solve this you have to know the surface area formula for a square prism which is 2a^2+4ah where a is an edge of the base and h is the height. Since 4.25 is the height, we just have to find a base edge. Since the base has an area of 16 inches and it is a square that has all equal sides, we know the base edge is 4 (4 times 4 =16). Now if you plug 4 in for a and 4.25 in for h, you get 100.

A tennis match requires that a player win three of five sets to win the match. If a player wins the first two sets, what is the probability that the player wins the match, assuming that each player is equally likely to win each set
Using it's concept, it is found that there is a 0.875 = 87.5% probability that the player wins the match.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, these following outcomes result in the player winning the match:
Wins the third set, with 0.5 probability.Loses the third set but wins the fourth, each with 0.5 probability.Loses the third and fourth sets but wins the fifth, each with 0.5 probability.Hence, the probability that he wins the match is given as follows:
p = 0.5 + 0.5² + 0.5³ = 0.875.

Patty tosses the coin and rolls the number cube 60 times. Predict how many times the coin will land on heads and the cube will land on an even number
Half of the time, the coin will land on heads and the cube will land on an even number when Patty tosses the coin and rolls the number cube 60 times.
What is binomial probabilities?The binomial probabilities is the experimental probability in which the total number of output values is 2, therefore it is known as binomial probabilities.
The number of independence variable in case of binomial experiments is fixed. Both the two output has the 1/2 chances to occur.
Patty tosses the coin and rolls the number cube 60 times.
For the coin, there are total 120 outcomes for 60 tosses, in which 60 favorable outcomes to land on heads. Thus, the probability the coin will land on heads is,
[tex]P=\dfrac{60}{120}\\P=\dfrac{1}{2}[/tex]
For the number cube, there are total 360 outcomes (6×60) for 60 rolls, in which 180 favorable outcomes (3×60) to land on even number. Thus, the probability the number cube will land on even number is,
[tex]P=\dfrac{180}{360}\\P=\dfrac{1}{2}[/tex]
Hence, half of the time, the coin will land on heads and the cube will land on an even number when Patty tosses the coin and rolls the number cube 60 times.

Answer:
A. x and y switch places and new y-value is the opposite (x,y) becomes (y-x)
Step-by-step explanation:
B went from (-1, 4) to (4, 1) and D went from (2, 1) to (1, -2). It is shown here that the x and y values have switched places, so we can eliminate choices C and D (x and y also did not increase by 4). We can see that both new y-values are the opposite of their original signs, -1 changing to 1, and 2 changing to -2. Option B only implies that the numbers switched places with no indication of the change in sign. If this were true, then B would go from (-1, 4) to (4, -1) and D would go from (2, 1) to (1, 2). Therefore, option A is the answer.

B ∪ C = (-∞, ∞)
B ∩ C = [1, 7)
Step-by-step explanation:
B ∪ C: The union of two sets or intervals is the set of elements which are in either set.
B ∩ C: The intersection of two sets or intervals is the set of elements which are in both sets.
Interval notation symbols
Square brackets [ ]: both endpoints are included in the set.
Round brackets ( ): both endpoints are excluded in the set.
Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.
Square, round [ ): left endpoint is included and right endpoint is excluded in the set.
Given:
B = {z | z ≥ 1}C = {z | z < 7}Therefore,
B = [1, ∞)
C = (-∞, 7)
Therefore, B ∪ C = (-∞, ∞)
As z is either less than 7, or equal to or more than 1 then the intersection is:
B ∩ C = {z | 1 ≤ z < 7} = [1, 7)

Answer:
Wyatt must get a score of 150 on Exam B in order to do equivalently well as he did on Exam A.
Step-by-step explanation:
Let's calculate the test statistic of each score based on the mean and standard deviation of each test.
This statistic will show us how far from the mean, measured in standard deviations, Wyatt's test score is.
The formula for the test statistic is:
[tex]\displaystyle Z = \frac{x- \mu}{\sigma}[/tex] x = observed value[tex]\mu[/tex] is the population mean [tex]\sigma[/tex] is the population standard deviationLet's calculate the test statistic for each test.
Exam A:
[tex]\displaystyle Z = \frac{45-35}{5} = \frac{10}{5}= 2[/tex]Exam B:
[tex]\displaystyle Z = \frac{x-100}{25}[/tex]Since we want the test statistic to be the same for both exam A and exam B, let Z = 2 and solve for x for Exam B.
[tex]\displaystyle 2 = \frac{x-100}{25} \\ 50 = x - 100 \\ x = 150[/tex]Wyatt must get a score of 150 on Exam B in order to do equivalently well as he did on Exam A. This score means that Wyatt is 2 standard deviations from the mean score on Exam B as he scored on Exam A.
2) Rachel wanted to drink exactly three bottles of water each day, so she bought twenty-six
bottles when they were on sale. How many more bottles will she need to buy on the last
day?
Answer:
1
Step-by-step explanation:
Twenty-Six is not a multiple of three so you know it won't be 26. Counting by threes goes 3, 6, 9, 12, 15, 18, 21, 24, 27, 30. Twenty-seven is the closest number to 26 which is higher than 26. Twenty-six + 1 = 27. That means that 1 is the answer.
