Absolute value is like how far from 0.

For example. -5 is 5 units away from 0. We can use the absolute value symbol to determine that the value is far away from 0 in how many units.

So the answer is C or the third one.

To determine the rank of a score of x=1, we need to use the concept of tied ranks in ranking.

Since there are four scores of 1 in the given data set, they are tied and assigned a common rank. To calculate this rank, we first find the ranks of the remaining scores:

Score: 1 1 1 1 3 6 6 6 9

Rank: 1 1 1 1 5 6 6 6 9

As we can see, the first four scores are tied and are assigned a rank of 1. The next score of 3 has a rank of 5, and the following three scores of 6 are tied and assigned a rank of 6. Finally, the score of 9 has a rank of 9.

Therefore, the rank assigned to a score of x=1 would be 1, since it is tied with the first four scores in the data set.

Answer:

11:55 is closest time time to mid night

Option D is correct, 12:03AM is the closet time to midnight.

Midnight is typically defined as the beginning of a new day, precisely at 12:00 AM.

In a 12-hour clock format, AM (ante meridiem) is used to represent the time before noon (from midnight to 11:59 AM), while PM (post meridiem) is used to represent the time after noon (from 12:00 PM to 11:59 PM).

12.06am is 6 minutes past midnight.

11.50am is 10 minutes from midday, or, if you prefer, 11 hours and 55 minutes past midnight.

The probability of getting one defective component per customer is very low, less than 1/14,254. The probability of getting five defective components to a single customer is also low, 1/14,254. And the probability of getting two defective components to two different customers and the rest of the customers getting none is 10/14,254.

(a) The probability that each customer will receive one defective component is the probability that the five defective components will be drawn in a specific order, divided by the total number of ways the 50 components can be drawn. There are 5049484746 ways that the 50 components can be drawn, and 5! (5 factorial) ways that the defective components can be drawn in a specific order. So the probability is (5!)/(5049484746) = 1/14,254.

(b) The probability that one customer will have drawn five defective components is the probability that all five defective components will be drawn in a row, divided by the total number of ways the 50 components can be drawn. There are 5049484746 ways that the 50 components can be drawn, and 5! (5 factorial) ways that the defective components can be drawn in a row. So the probability is (1!)/(5049484746) = 1/14,254,

(c) The probability that two customers will receive two defective components each, two none, and the other one, is the probability that the five defective components will be drawn in a specific order and then divided among the five customers in a specific way, divided by the total number of ways the 50 components can be drawn. The number of ways to divide the defective components among the customers is 5!/(2!2!1!) = 10. There are 5049484746 ways that the 50 components can be drawn, and 5!

Step-by-step explanation:

this situation creates a right triangle with the ladder being the hypotenuse and legs distance from base of ladder and height of ladder (h) up the wall

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

h² + 5² = 15²

h² + 25 = 225 ( subtract 25 from both sides )

h² = 200 ( take square root of both sides )

h = \(\sqrt{200}\) ≈ 14 feet ( to the nearest foot )

The sοlutiοns tο the equatiοn are x = 15 οr x = -2.

Expressions that perform the same function despite their appearance are said to be equivalent. If two algebraic expressions are equivalent, then when the variable is set to the same value, they have the same value.

We must first simplify this equation by placing all the terms on one side of the equation in order to solve it.

Then we can factοr the denοminatοr and simplify further tο sοlve fοr x.

Starting with the given equatiοn:

\(7/(x-9) + 3x/(x+5) = (2x+1)/(x-9)\)

We can start by multiplying bοth sides by (x-9)(x+5) tο get rid οf the denοminatοrs:

\(7(x+5) + 3x(x-9) = (2x+1)(x+5)\)

Expanding the brackets and simplifying, we get:

\(7x + 35 + 3x^2 - 27x = 2x^2 + 11x + 5\)

Rearranging and simplifying further, we get:

\(x^2 - 13x - 30 = 0\)

Tο sοlve fοr x, we can factοr the left-hand side οf the equatiοn:

\((x - 15)(x + 2) = 0\)

Setting each factοr tο zerο and sοlving fοr x, we get:

x - 15 = 0 οr x + 2 = 0

Sο x = 15 οr x = -2.

Answer:

A because it has both the slope and the y-intercept

Using the Pythagorean theorem,

Given that: a = 13 inches and c = 51 inches. Plugging in the values, we get:
13² + b² = 51²
169 + b² = 2601 ⇒ b² = 2432
Finally, find the square root of 2432 to get the width:
b ≈ 49.3 inches
So, the width of the screen is approximately 49.3 inches.

Using the Pythagorean theorem, we can find the width of the flat-screen television. Given the diagonal length (51 inches) and the height (13 inches), we can solve for the width.

To find the width of the screen, we need to use the Pythagorean theorem. We know that the diagonal of the screen is 51 inches and one side of the screen (the height) is 13 inches.

So, we can use the formula:
c^2 = a^2 + b^2

where c is the diagonal (51 inches), a is the height (13 inches), and b is the width (what we're trying to find).

Plugging in the values:
51^2 = 13^2 + b^2
2601 = 169 + b^2
2432 = b^2
b ≈ 49.3

Therefore, the width of the screen is approximately 49.3 inches.

Answer:

\(x + \frac{23}{4} = \frac{41}{7} \\ \frac{41}{7} - \frac{23}{4} \\ = \frac{3}{28} \)

Answer:

To solve this problem, we need to subtract 2 3/4 from 4 1/7:

4 1/7 - 2 3/4 = (28/7 + 1/7) - (11/4 - 3/4)

= 29/7 - 8/4

= 29/7 - 2

= (29 - 14)/7

= 15/7

Therefore, we can add 15/7 to 2 3/4 to obtain 4 1/7:

2 3/4 + 15/7 = (14/4 + 3/4) + (15/7)

= 17/4 + 15/7

= (119/28 + 60/28)

= 179/28

= 4 1/7

So the answer is 15/7.

The estimated total time for all five pools is approximately 13.85 hours.

To estimate the time required to install the fifth pool using the learning curve, we can use the formula:

Time for nth unit = Time for first unit * (n^b)

Where:

Time for nth unit is the estimated time to install the nth pool

Time for first unit is the estimated time to build the first pool (30 hours)

n is the number of units (in this case, n = 5 for the fifth pool)

b is the learning curve exponent (85% learning rate corresponds to b = log(0.85) / log(2))

Let's calculate the estimated time for the fifth pool:

b = log(0.85) / log(2) ≈ -0.157

Time for fifth pool = Time for first pool * (5^b)

Time for fifth pool = 30 * (5^(-0.157))

Calculating this, we find:

Time for fifth pool ≈ 30 * 0.6764 ≈ 20.29 hours

Therefore, the estimated time required to install the fifth pool is approximately 20.29 hours.

To calculate the total time for all five pools, we need to sum the time required for each pool from the first to the fifth. Since the learning curve assumes decreasing time with increasing units, we can use a summation formula:

Total time for all units = Time for first unit * ((1 - (n^b)) / (1 - b))

Using this formula, let's calculate the total time for all five pools:

Total time for all five pools = Time for first pool * ((1 - (5^b)) / (1 - b))

Total time for all five pools = 30 * ((1 - (5^(-0.157))) / (1 - (-0.157)))

Calculating this, we find:

Total time for all five pools ≈ 30 * 0.4615 ≈ 13.85 hours

Therefore, the estimated total time for all five pools is approximately 13.85 hours.

I don't know what the parent function is. you did not specify that.

I guess it is f(x) = x² ?

anyway, x² is the prime example of a parabola, which simply opens upward and has the vertex (its minimum) at 0, 0.

now, g(x) is first of all multiplying this by -1.

that turns the original curve upside-down.

therefore, g(x) opens downward, and it has a maximum.

because of the mentioned upside-down action, this is a reflection across the x-axis.

the multiplication by 1/4 actually decreases the functional values compared to the basic x² curve, so the curve is below the x² curve and that means it stretches the original curve.
