False, a grouped frequency distribution does not necessarily have the same number of groups as there are data items.

False.

A grouped frequency distribution does not necessarily have the same number of groups as there are data items.

In fact, the number of groups in a grouped frequency distribution is determined by the range of the data and the desired width of each group.

The purpose of grouping data is to simplify and summarize large sets of data, making it easier to interpret and analyze.

By dividing the data into groups or intervals, you can condense the information and identify patterns or trends.

The number of groups will depend on factors such as the range of values and the desired level of detail in the distribution.

The expected value and the standard deviation of the points per game for the player is -6.5 and 65.43 respectively.

Given:

In a certain computer card game, the player is awarded 5 points for each card that is moved to a correct position. The player is penalized 10 points for each minute the game is played. Let the random variable X represent the number of cards moved to a correct position, and let the random variable Y represent the number of minutes the game is played.

From the given table:

E ( X ) = 9.5 * 5 points

= 47.5

E ( Y ) = 5.4 * - 10

= -54

E ( X + Y ) = 47.5 + ( -54 )

= 47.5 - 54

= -6.5

SD ( X ) = 12.5 * 5

= 64.5

SD ( Y ) = - 11

SD ( X + Y ) = \(\sqrt{64.5^2 + (-11)^2}\)

So, the signs we need to fill in are: (y + 3)(x - 1)

Factors are sets of digits that when added together, yield another integer. For instance: Since 2 + 3 Equals 6, the digits 2 and 3 seem to be factors of 6. Many things can affect a number!

To factor xy - y + 3x - 3, we can group the first two terms and the last two terms:

(xy - y) + (3x - 3) = y(x - 1) + 3(x - 1)

Notice that (x - 1) is a common factor of both terms, so we can factor it out:

y(x - 1) + 3(x - 1) = (x - 1)(y + 3)

So, we have:

xy - y + 3x - 3 = (x - 1)(y + 3)

To fill in the blanks, we use the factors we found:

(x - 1)(y + 3) = y(x - 1) + 3(x - 1) = xy - y + 3x - 3

So, the signs we need to fill in are:

Step-by-step explanation:

The expected value is the long-term average outcome of a random variable. It is calculated by multiplying each possible outcome by its probability and summing them up. In simpler terms, it represents the average value we expect to get over many trials.

The expected value is a concept in probability and statistics that represents the long-term average outcome of a random variable. It is also known as the mean or average. To calculate the expected value, we multiply each possible outcome by its probability and sum them up.

For example, let's say we have a fair six-sided die. The possible outcomes are numbers 1 to 6, each with a probability of 1/6. To find the expected value, we multiply each outcome by its probability:

Summing up these values gives us:

1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6 = 21/6 = 3.5

Therefore, the expected value of rolling a fair six-sided die is 3.5. This means that if we roll the die many times, the average outcome will be close to 3.5.

The area of the sign is 35 square feet. The solution has been obtained by using the area of the trapezoid.

The entire area occupied by the sides of a trapezoid is its area. A trapezoid's area is determined by how many unit squares fit inside of it.

We know that area of the trapezoid is

Area (A) = (a + b ) * h/ 2

Now, here we are given the following:

a = 8

b = 6

h = 5

Now, on substituting these values in the formula, we get

⇒A = (8 + 6 ) * 5 / 2

⇒A = (14 * 5) / 2

⇒A = 70 / 2

⇒A = 35 square feet

Hence, the area of the sign is 35 square feet.

Answer:

The possible original values of both products are ₹2 or ₹1

Step-by-step explanation:

The question is a word problem leading to simultaneous equations

Let 'x' represent the initial value of the pen and pencil

Therefore;

The final cost of the pen = x + ₹4

The final cost of the pencil = 5·x - ₹6

x + ₹4 > 5·x - ₹6

∴  ₹4 + ₹6 > 5·x - x

₹10 > 4x

₹10/4 > x

₹2.5 > x

Given that x is a natural number, therefore

x ≤ ₹2

The possible original values of both products are ₹2 or ₹1

The possible original value of both products is ₹ 1 and  ₹ 2.

The question is a word problem

Let x represent the initial cost of the pen and pencil since they were initially the same price.

When the costs of the pen was increased by ₹4, its new price is x' = x + 4.

Also, the cost of pencil became ₹6 less than 5 times its original value. So, the new price of the pencil is x" = 5x - 6.

After the revised cost, if the pen was more expensive than the pencil, then we have x' > x".

So, x + 4 > 5x - 6

x - 5x > - 4 - 6

-4x > - 10

x < -10/-4

x < 2.5

Since the initial price of the both products was a natural number, the two natural number less than 2.5 are 1 and 2.

So, the possible original value of both products is ₹ 1 and  ₹ 2.

There are plenty of unique ways to wrap presents beautifully. The quickest way that doesn't even require a box: Create a gift bag out of another ..

Step-by-step explanation:

There's something about a pile of presents under the tree that catches the eye—no matter how they're wrapped. But when your gifts look like something straight out of a storybook, it instantly adds to the Christmas magic.

We know what you're thinking, though: Who has time for that between decorating the house, shopping for your loved ones, prepping for the Christmas party, and planning your holiday meal? What if we told you that creating presents that look professionally wrapped is actually fairly simple?

There are plenty of unique ways to wrap presents beautifully. The quickest way that doesn't even require a box: Create a gift bag out of another household staple, like an old (but clean) pillowcase or a brown paper bag. You'd be surprised what a simple stamp, paint pen, or stylish ribbon can do to breathe new life into these objects. But if you have a little more time to get creative, why not raid your craft closet and make something truly special and Pinterest-worthy, like lace-covered packages or custom paper created by your kids?

No matter which direction you go and no matter what holiday you're celebrating—Christmas, a kids' birthday, or a life event like a wedding or a baby shower—you'll find plenty of inspiration, plus step-by-step gift wrapping instructions, here. When you're done, we're certain that present is going to be so pretty, it'll almost be too hard to open

The Sara would choose first box or third box to pack the gift because the paper available is sufficient for the first or third box.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape.

Sara has a single piece of wrapping paper with an area of 400 in2,

Surface area of the paper = 400 square in

To find right box that Sara would be able to use for the gift that she could completely wrap with her piece of wrapping paper we must find the surface area of the each box.

The surface area of the cuboid is given by:

SA = 2(lw+wh+lh)

Where, l is the length, w is the width, and h is the height of the cuboid.

For the first box:

l = 15 in, w = 4.2 in, and h = 4.5 in

SA = 2(15×4.2+4.2×4.5+15×4.5)

SA = 2(63+18.9+67.5)

SA = 298.8 square in

For the second box:

l = 6.3 in, w = 8.1 in, and h = 12 in

SA = 2(6.3×8.1+8.1×12+12×6.3)

SA = 2(51.03+97.2+75.6)

SA = 447.66 square in

For the third box:

l = 7.5 in, w = 7.5 in, and h = 7.5 in

SA = 2(7.5×7.5+7.5×7.5+7.5×7.5)

SA = 2(168.75)

SA = 337.5 square in

If we compare surface area of the papaer to surface area of the boxes, we will see Sara can use first box or either third box becasue surface area of the paper which is 400 in² is sufficient for the boxes whose surface areas are 298.8 square in, and 337.5 square in.

Thus, the Sara would choose first box or third box to pack the gift because the paper available is sufficient for the first or third box.

Answer:

\(a_{n}\) = 6n - 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

8 - 2 = 14 - 8 = 6

This indicates the sequence is arithmetic with n th term

\(a_{n}\) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 6 , thus

\(a_{n}\) = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

Thus the formula representing the sequence is

\(a_{n}\) = 6n - 4

The distance between the two parallel planes x - 2y + 2z = 4 and 4x - 8y + 8z = 1 is 1/√21 units.

To find the distance between two parallel planes, we can consider the normal vector of one of the planes and calculate the perpendicular distance between the planes.

First, let's find the normal vector of one of the planes. Taking the coefficients of x, y, and z in the equation x - 2y + 2z = 4, we have the normal vector n1 = (1, -2, 2).

Next, we can find a point on the other plane. To do this, we set z = 0 in the equation 4x - 8y + 8z = 1. Solving for x and y, we get x = 1/4 and y = -1/2. So, a point on the second plane is P = (1/4, -1/2, 0).

The distance between the planes is the perpendicular distance from the point P to the plane x - 2y + 2z = 4. Using the formula for the distance between a point and a plane, we have:

distance = |(P - P0) · n1| / |n1|

where P0 is any point on the plane. Let's choose P0 = (0, 0, 2), which satisfies the equation x - 2y + 2z = 4.

Substituting the values, we get distance = |(1/4, -1/2, -2) · (1, -2, 2)| / |(1, -2, 2)| = 1/√21 units.

Therefore, the distance between the two parallel planes is 1/√21 units
