Georgianna wants to use the linear model associated with the data in the table to make a prediction.Which range of time values describes the entire interval over which she would be interpolating?

A) 0 to 5 minutes
B) 0 to 18 minutes
C) 0 to 30 minutes
D) 18 to 30 minutes

Answers

Answer 1

Answer:

the data in the table in the attached figure

we know that

Linear model regression is used to predict the relationship between 2 variables by fitting the observed data in a linear equation.

The range of time values that describes the interpolation that Georgianna would be making is from

$0$ $to$ $30$ $minutes$

Because

the minimum value of the time of the data in the table is equal to $0$ minutes

the maximum value of the time of the data in the table is equal to $30$ minutes

therefore

the answer is the option

$C) 0 to 30 minutes$

Answer 2

Answer: Georgianna wants to use the linear model associated with the data in the table to make a prediction. The range of time values that describes the entire interval over which she would be interpolating is 18 to 30 minutes. The answer is letter D.

Solve and SHOW YOUR WORK for the equation 4m + 2(m + 1) = 9m + 5Solve and SHOW YOUR WORK for the equation 3(4x – 2) = 9 + 2x + 5

Answers

4m + 2(m + 1) = 9m + 5

What we need to do here is combine like terms, then apply the inverse operation, and finally, isolate the variable.

Here's how it's done:

4m + 2m + 2 = 9m + 5
4m and 2m are like terms, so add them together.
4m + 2m = 6m

6m + 2 = 9m + 5
-6m -6m

2 = 3m + 5
-5 -5

3m = -3
3m/3 = -3/3
m = -1 should be your answer.

Next one: 3(4x – 2) = 9 + 2x + 5
12x - 6 = 9 + 2x + 5
-2x -2x

10x - 6 = 9 + 5
10x - 6 = 14
+6 +6

10x = 20
x = 2 should be your answer.

The data set below represents the ages of 36 executives. Fine the percentile that corresponds to an age if 36 years old.

Answers

Answer: The percentile that corresponds to an age of 36 years old in the given data set is approximately 22.22%.

Step-by-step explanation:

To find the percentile that corresponds to an age of 36 years old in a data set representing the ages of 36 executives, we can use the following steps:

Step 1: Arrange the data set in ascending order.

- Let's assume the data set is as follows (in ascending order): 28, 30, 31, 32, 33, 34, 35, 36, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63.

Step 2: Calculate the rank of the given age.

- The rank is the position of the given age within the data set.

- In this case, the given age is 36 years old, and its rank is 8 because it is the 8th value in the data set.

Step 3: Calculate the percentile using the rank and the total number of data points.

- The percentile can be calculated using the following formula:

Percentile = (Rank / Total number of data points) x 100

- In this case, the total number of data points is 36 (since there are 36 executives' ages in the data set).

- Plugging in the values, we get:

Percentile = (8 / 36) x 100

Percentile ≈ 22.22 (rounded to two decimal places)

A merry-go-round has a radius of 10 ft. To the nearest tenth of a foot, what distance does the merry-go-round cover when it rotates through an angle of 72°?For my first try, I got 62.9 as my answer, and it was marked wrong. I did this a second time, and got 12.6. I would like to check with anyone else to see if I got the answer right.

The answers for this question were:

62.9, 12.6, 25.1, or 125.7

Answers

Answer:

12.6

Step-by-step explanation:

The distance covered by the merry-go-round if makes a complete circle (360°) is its circumference:

circumference = 2*π*radius = 2*π*10 = 62.8 ft

This distance corresponds to 360°, for 72°:

62.8 ft / x ft = 360° / 72°

x = (72/360)*62.8

x = 12.6 ft

Yes, the correct answer is 12.6 ft.

Using the formula of arc length, that is
s = rθ
where s = arc length, r = radius, θ = angle (unit must be in radian)
With r = 10 ft and θ = 72 deg ( π/180 deg) = 1.26 rad,
s = (10)(1.26) = 12.6 ft

PLS HELP ASAP Consider a standard deck of 52 playing cards with 4 suits. If A is the event of drawing a 6 from the deck, and B is the event of drawing a black playing card from the deck, what is the intersection of A and B? (Remember that the black cards are spades and clubs.) A) drawing a 6, a club, or a spade B) drawing the 6 of hearts or the 6 of diamonds C) drawing a 6, a heart, or a diamond D) drawing the 6 of clubs or the 6 of spades

Answers

Answer:

Correct answer is option D) drawing the 6 of clubs or the 6 of spades

Step-by-step explanation:

Given that:

A standard deck of 52 playing cards with 4 suits.

A be the event of drawing a card with 6 from the deck.

B be the event of drawing a black card from the deck.

So, event A will have 4 possibilities i.e. {6 of club, 6 of spade, 6 of diamond, 6 of heart}

And event B will have 26 possibilities {Any card (including 6) from club or spade}

Intersection of two sets is defined as the common elements in the two sets.

As per the explanation of the sets and elements in the sets given above:

If we take intersection it will be:

{6 of club or 6 of spade}

Hence, Correct answer is option D) drawing the 6 of clubs or the 6 of spades

Final answer:

The intersection of events A and B is represented by drawing the 6 of clubs or the 6 of spades (D) .

Explanation:

The intersection of events A (drawing a 6) and B (drawing a black playing card) refers to the cards that satisfy both criteria. In this case, event A consists of the card 6 from any suit, while event B consists of the black cards (spades and clubs) from any value. To determine the intersection, we need to find the cards that are both a 6 and black.

Looking at the options given, option D) drawing the 6 of clubs or the 6 of spades represents the cards that satisfy both events. The 6 of clubs and the 6 of spades are black cards and also have a value of 6. Therefore, the intersection of events A and B is represented by option D).
