Answer:

The experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials or observations.

In this case, the event is choosing a monitor with no defects, and the number of times the event occurs is 45. The total number of monitors is 50.

So, the experimental probability of choosing a monitor with no defects is:

45/50 = 0.9

Therefore, the experimental probability that a monitor chosen at random has no defects is 0.9 or 90%.

Step-by-step explanation:

1. The base of the pyramid is a square so the base of all of the triangles will be 14in.

2. Since the height of the triangle is 4in, the area of 1 triangle will be (14x4)/2 which is 28in^2.

3. Because we are finding lateral area we only need to find the area of the triangles so you do 28x4 which is 112in^2.

Another easy way to find the lateral area of a pyramid is by finding the perimeter of the base which in this case is 56, multiplying it by the slant height which in this case is 4 and dividing by 2. The equation would be (56x4)/2 which is also 112.

Answer: 1.6 x 10x10x10

Step-by-step explanation:

The exponent (3) signifies that you should write three tens.

1.6 x 10³ is written in standard form as 1600.

Scientific notation is a way of writing very large or very small numbers It is usually used to depict microscopic or macroscopic objects. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

        Scientific forms of numbers are compact and take up less space. They are raised to exponents, whereas standard forms are complex and provide the numerical notation taking up more space.

According to the given question the number 1.6×10³ is written in scientific form we have to convert this number into standard form.

We know 10³ = 1000.

∴ 1.6×10³ = 1.6 × 1000.

= 1600.

13/8 in

Step-by-step explanation:

1) Since you know that there are 2 sticks with a length of 1/8 in, 3 sticks with a length of 2/8 in, and 1 stick with the length of 5/8 in, we need to add them together.

2) They have the same denominator, so we can add the fractions together easily. 1/8+1/8+2/8+2/8+2/8+5/8=13/8

Answer:

37.5 square feet

Step-by-step explanation:

Let me break it down into simple terms:

The question states, "cube with this net".

A cube has all 6 surfaces that are equal.  The surface area is the area of each side added up.  

In this case, since this net would form a cube, we can use the formula:

6·area of 1 square to get the surface area of the entire net.

We know that to find the area of a shape, it's simply length times width:

2.5x2.5

=6.25

Now, substitute that into the original equation (6·area of 1 square)

6(6.25)

=37.5

The surface area of this net is 37.5 square feet.

Hope this helps! :)

Answer:

45

Step-by-step explanation:

The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.

By using mean and median, we can know which team typically has the tallest players

For the Allstars:

Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches

Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73

Median = 68 inches

For the Champs:

Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches

Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75

Median = 67 inches

The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.

Answer:

0.99

Step-by-step explanation:

To find the experimental probability, divide the number of can openers that passed inspection by the total number of can openers in the batch:

Passed inspection: [tex]19,354 -253=19.101[/tex]
Experimental probability: [tex]19,101[/tex]÷[tex]19,354=0.987[/tex]
Which rounded to the nearest hundredth is 0.99

Answer:

The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:

y - (-2) = 3(x - (-1))

Simplifying this equation, we get:

y + 2 = 3(x + 1)

So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).

The area of the fragment is [tex]10cm^{2}[/tex] if each square on the grid has the area of [tex]1cm^{2}[/tex].

We have been given the area of one square on the grid is [tex]1cm^{2}[/tex].

We have to find the total area of the fragment.

Let's calculate the total area of the fragment.

We have been given the area of one square in the fragment is [tex]1cm^{2}[/tex] .

Step 1: Count the number of squares present in the fragment.

Adding the number of colored squares in the row,

= 4 + 3 + 2 + 1

= 7 + 3

= 10

Step 2: Multiplying the number of squares in a fragment by the area of one square.

Now, forming an expression to calculate the total area,

= Number of squares X Area of one square

Substituting the values,

= [tex]10(1cm^{2} )[/tex]

= [tex]10cm^{2}[/tex]

Therefore, the area of the fragment is [tex]10cm^{2}[/tex]

Correct question: Find the area of the fragment, if each square on the grid has an area of [tex]1cm^{2}[/tex].

The area of the fragment is approximately 10 cm².

Hence, option D is correct.

Use the concept of the triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

Gieven that,

Eeach grid has area = 1 cm²

Since each grid is of square shape,

Therefore,

Heigh of each grid = 1 cm

And the width of each grid = 1 cm

Now from the figure,

The height of the triangle = 4 cm

The width of the triangle ≈ 5 cm

Since knowing that,

Area of triangle = (1/2) x base x height

Therefore,

Area of the shaded region ≈ (1/2)x4x5

Area of the shaded region ≈ 10 cm²

Hence,

The area of the fragment is approximately 10 cm² which is option D.

Step-by-step explanation:

Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:

Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28

Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:

Total spent by Anna = $2.16/gallon * 15 gallons = $32.40

To find the difference in their expenditures, we subtract Anna's total from Jeff's total:

Difference = Total spent by Jeff - Total spent by Anna

Difference = $35.28 - $32.40 = $2.88

Therefore, Jeff spends $2.88 more than Anna on gas.

Step-by-step explanation:

we want to find the probabilty for pink

so lets add all of the marbels together

all them equal 38

we only want to find the probabilty for pink

so we are gonna put 12 over 38 ( which looks like this : 12/38)

we want to simplify it and the simplified verson of 12/38 is 6/19

that could be your total number if they want it as a fraction if they want it as a decimal put 6/19 in your calcalator and that will come up as 0.315789473684 then press times 100 which will put it in the correct spot with will come up as 31.5789473684 since there is a 7 next to the 5

Answer:

IQR = 13

Step-by-step explanation:

First, lay out the set of data in a line.

20, 25, 30, 30, 31, 40, 41, 49

Next, we have to find the median, which is the middle of the set of data.

It is between 30 and 31, which is 30.5. Another way to find it is:

30 + 31 = 61

61 ÷ 2 = 30.5

Using that, we mark it between 30 and 31. Next, use the line of the mark, you use to separate the data into two.

20, 25, 30, 30 | 31, 40, 41, 49

Now, you find the median for each side. The left side will be the lower quartile, and the right side will be the upper quartile.

LQR = 25 + 30 = 27.5

UQR = 40 + 41 = 40.5

Now to find the IQR, you subtract the LQR from the UQR:

40.5 - 27.5 = 13

IQR = 13
