Alex has 13 video games. How many fewer video games does John have than Alex if they have 21 games altogether
Answers
To determine how many fewer video games John has than Alex, we need to find the difference between the number of video games each person has. John has 8 fewer video games than Alex.
John has 8 fewer video games than Alex if they have 21 games altogether. Alex has 13 video games, and together they have 21 games, so we can subtract 13 from 21 to find the number of games John has.
21 - 13 = 8
Therefore, John has 8 fewer video games than Alex.

What algebraic rule did you use to preform this
translation????
Answers
Answer:
In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a
new shape (called the image). A translation is a type of transformation that moves each point in a figure the same
distance in the same direction. Translations are often referred to as slides. You can describe a translation using words
like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.
1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.
2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and
y coordinates are translated to x−7 and y+5.

Determine whether the sequence is increasing, decreasing, or not monotonic.an = (7n-8) / (8n+3)increasingdecreasingnot monotonicIs the sequence bounded?boundednot bounded
Answers
The sequence an = (-4)/(n+4) is decreasing and bounded. To see that sequence is decreasing, notice n increases, denominator n+4 increases, while numerator -4 stays same. Therefore, fraction (-4)/(n+4) gets smaller as n increases, sequence is decreasing.
To see that the sequence is bounded, note that the denominator n+4 is always positive, and the numerator -4 is negative. Therefore, the sequence is always negative, and its absolute value is decreasing. Since the sequence is always negative and decreasing, it is bounded below by zero.
The sequence an = (7n-8)/(8n+3) is decreasing and bounded. To see that the sequence is decreasing, notice that as n increases, the denominator 8n+3 increases faster than the numerator 7n-8.
Therefore, the fraction (7n-8)/(8n+3) gets smaller as n increases, meaning that the sequence is decreasing. To see that the sequence is bounded, note that the denominator 8n+3 is always positive integer, and the numerator 7n-8 is increasing.
Therefore, the sequence is always positive and decreasing, meaning that it is bounded above by its first term, which is (71-8)/(81+3) = -1/11.

There is a probability of 0.61 that a person will enter a store with a creative window display. Suppose that a number of potential customers walk by. What is the probability that the fourth person will be the first customer to enter the store?
(b). Find the probability that the fourth person will be the first customer to enter the store. (Round your answer to three decimal places.)
Answers
To determine the probability that the fourth person will be the first customer to enter the store, we can use the geometric distribution.
The geometric distribution models the number of trials needed to achieve the first success (entering the store in this case) in a series of independent Bernoulli trials (each potential customer walking by). The probability of success in each trial is given as 0.61.
The probability that the fourth person will be the first customer to enter the store is equal to the probability of three consecutive failures (the first three people not entering the store) followed by a success (the fourth person entering the store).
The probability of failure in each trial is given by (1 - 0.61) = 0.39.
So, the probability that the fourth person will be the first customer to enter the store is calculated as follows:
P(fourth person is the first customer) = P(failure) * P(failure) * P(failure) * P(success)
= 0.39 * 0.39 * 0.39 * 0.61
≈ 0.0602
Therefore, the probability that the fourth person will be the first customer to enter the store is approximately 0.0602, or 6.02%.

Tony went on holiday to Canada.
His flights cost a total of £1600
Tony stayed for 12 nights.
His hotel cost $184 per night.
Tony used wifi for 9 days.
Wifi cost $6 per day.
Tony took a taxi 6 times costing a mean average of $27 per taxi journey.
The exchange rate was $1.83 to £1
Work out the total cost of the flights, the hotel room, the wifi and 6 taxi journeys.
Give your answer in pounds.
Answers
Answer:
Step-by-step explanation:
(12 nights)($184) = $2208
(9 nights)($6) = $54
(6 taxi rides)($27) = $162
$2208 + $54 + $162 = $2424
We will use a ratio to calculate American dollars to pounds
2424/x = 1.83/1
Cross multiply
1.83x=2424
Divide
= ~£1324.59
£1324.59 + £1600 = £2924.59
The answer is ~2924.59 pounds
The total cost of the flights, the hotel room, the wifi, and 6 taxi journeys for Tony's holiday in Canada is approximately £2925.13.
Given that Tony is vacationing in Canada, his flight cost is £1600, he stayed for 12 nights, his hotel cost $184 per night, Tony used wifi for 9 days. Wifi cost $6 per day. Tony took a taxi 6 times costing a mean average of $27 per taxi journey.
The exchange rate was $1.83 to £1.
We need to find the total cost his spend in the vacation.
To calculate the total cost of Tony's holiday, we need to convert all the expenses to pounds and then sum them up.
Flights cost: £1600
Hotel cost per night: $184
Hotel cost for 12 nights: 12 nights x $184/night = $2208
Wifi cost per day: $6
Wifi cost for 9 days: 9 days x $6/day = $54
Taxi cost per journey (mean average): $27
Total taxi cost for 6 journeys: 6 journeys x $27/journey = $162
Now, we need to convert the costs from dollars to pounds using the exchange rate of $1.83 to £1.
Flights cost in pounds: £1600
Hotel cost in pounds: $2208 / $1.83 = £1207.10
Wifi cost in pounds: $54 / $1.83 = £29.51
Taxi cost in pounds: $162 / $1.83 = £88.52
Finally, we can calculate the total cost in pounds:
Total cost = Flights cost + Hotel cost + Wifi cost + Taxi cost
Total cost = £1600 + £1207.10 + £29.51 + £88.52
Total cost = £2925.13
So, the total cost for Tony's holiday in Canada is approximately £2925.13.

We would like to test the hypotheses H0: μ = 130, HA: μ > 130. We found t = 2.73 with 5 degrees of freedom. What is the appropriate p-value.?
Answers
The appropriate p-value for the given test statistic and hypotheses is approximately 0.0253.
What is p-value?Tο determine the apprοpriate p-value fοr the given hypοthesis test, we need tο use the t-distributiοn and the t-statistic value οbtained.
Given:
Null hypοthesis (H0): μ = 130 (pοpulatiοn mean)
Alternative hypοthesis (HA): μ > 130 (pοpulatiοn mean)
T-statistic: t = 2.73
Degrees οf freedοm: df = 5
Tο calculate the p-value, we cοmpare the t-statistic tο the t-distributiοn.
Since the alternative hypοthesis is μ > 130, it is a οne-tailed test, and we are interested in the right tail οf the t-distributiοn.
Using a t-table οr a statistical sοftware, we can determine the p-value assοciated with the t-statistic and the degrees οf freedοm.
Fοr a t-statistic οf 2.73 with 5 degrees οf freedοm, the p-value is apprοximately 0.0257 (assuming a twο-tailed test).
Since we have a οne-tailed test, the apprοpriate p-value is half οf the twο-tailed p-value:
p-value = 0.0257 / 2 = 0.01285
Therefοre, the apprοpriate p-value fοr the given hypοthesis test is apprοximately 0.01285.

show that the equation represents a sphere, and find its center and radius. x^2 y^2 z^2-2x-4y 8z =15
Answers
The center of the sphere is (1, 2, -4), and its radius is 6 units.
A sphere is a three-dimensional geometric shape that is perfectly symmetrical, resembling a ball or a round object. It is defined as the set of all points in three-dimensional space that are equidistant from a fixed center point.
A sphere is characterized by its center, which represents the point from which all points on the sphere are equidistant, and its radius, which is the distance from the center to any point on the sphere's surface.
To determine if the equation represents a sphere, we need to rewrite it in a standard form: (x - a)² + (y - b)² + (z - c)² = r^2, where (a, b, c) represents the center of the sphere and r represents its radius.
Let's analyze the given equation: x² y² z² - 2x - 4y + 8z = 15
We can complete the square for each variable to put it in the standard form:
x² - 2x + y² - 4y + z² + 8z = 15
(x² - 2x + 1) + (y² - 4y + 4) + (z² + 8z + 16) = 15 + 1 + 4 + 16
(x - 1)² + (y - 2)² + (z + 4)² = 36
Now we can see that the equation represents a sphere with center (1, 2, -4) and radius r = sqrt(36) = 6. Therefore, the center of the sphere is (1, 2, -4), and its radius is 6 units.

Answers
The solved vectors are;
(a) 3u - 5v = [-9, 12, 12, 9, 9, -3] - [-5, 40, 0, 10, -15, 25] = [-9 + 5, 12 - 40, 12 - 0, 9 - 10, 9 + 15, -3 - 25] = [-4, -28, 12, -1, 24, -28]
(b) u + 4v - 2w = [-3, 4, 4, 3, 3, -1] + [-4, 32, 0, 8, -12, 20] - [2, 4, -2, 0, 8, -4] = [-3 - 4 + 2, 4 + 32 - 4, 4 + 0 + 2, 3 + 8 - 0, 3 - 12 + 8, -1 + 20 + 4] = [-5, 32, 6, 11, -1, 23]
(c) 4u - 6v + 3w = [-12, 16, 16, 12, 12, -4] - [-6, 48, 0, 12, -18, 30] + [3, 6, -3, 0, 12, -6] = [-12 + 6 - 3, 16 - 48 +
Given the vector u = [-3, 4, 4, 3, 3, -1], we are asked to compute the following vectors: (a) 3u - 5v, (b) u + 4v - 2w, and (c) 4u - 6v + 3w, where v = [-1, 8, 0, 2, -3, 5] and w = [1, 2, -1, 0, 4, -2].
To compute the vector 3u - 5v, we need to multiply each component of u by 3 and subtract 5 times each component of v. This can be done by performing the operations element-wise:
3u - 5v = [3*(-3), 34, 34, 33, 33, 3*(-1)] - [5*(-1), 58, 50, 52, 5(-3), 5*5]
Simplifying the expression, we get:
3u - 5v = [-9, 12, 12, 9, 9, -3] - [-5, 40, 0, 10, -15, 25] = [-9 + 5, 12 - 40, 12 - 0, 9 - 10, 9 + 15, -3 - 25] = [-4, -28, 12, -1, 24, -28]
For the vector u + 4v - 2w, we can apply similar element-wise operations:
u + 4v - 2w = [-3, 4, 4, 3, 3, -1] + 4[-1, 8, 0, 2, -3, 5] - 2[1, 2, -1, 0, 4, -2]
Simplifying, we get:
u + 4v - 2w = [-3, 4, 4, 3, 3, -1] + [-4, 32, 0, 8, -12, 20] - [2, 4, -2, 0, 8, -4] = [-3 - 4 + 2, 4 + 32 - 4, 4 + 0 + 2, 3 + 8 - 0, 3 - 12 + 8, -1 + 20 + 4] = [-5, 32, 6, 11, -1, 23]
Lastly, for the vector 4u - 6v + 3w, we perform the element-wise operations as follows:
4u - 6v + 3w = 4[-3, 4, 4, 3, 3, -1] - 6[-1, 8, 0, 2, -3, 5] + 3[1, 2, -1, 0, 4, -2]
Simplifying, we get:
4u - 6v + 3w = [-12, 16, 16, 12, 12, -4] - [-6, 48, 0, 12, -18, 30] + [3, 6, -3, 0, 12, -6] = [-12 + 6 - 3, 16 - 48 +

Answer:
10,000 times Larger
Step-by-step explanation:
To determine the multiple larger for 86,000,000 than 8,600, we simply will use the division operation and the result will be the multiple.
86,000,000 / 8,600 = 10,000
Hence, the number 86,000,000, is 10,000 times larger than 8,600.
Another method is simply to look at the additional zeroes that 86,000,000 has in comparison to 8,600. Since we can see that 86 is the only non-zero digit within the two numbers, we can use the properties of the decimal system to compare. Note that 86,000,000 has 6 zeroes, while 8,600 has two zeros. This means that we will need 4 zeroes as part of our tens multiple, so we can say that 10,000 is the multiple. Once again, we see that 86,000,000 is 10,000 times larger than 8,600.
