The experimental probability of the next sandwich sold being tuna on wheat bread is 23 out of 137 sandwiches sold, or approximately 0.168.

The problem describes an experimental probability scenario where stopping after having recorded multiple outcomes does not affect the probability of the next outcome. Experimental probability is calculated by taking the number of times an event occurs and dividing it by the total number of trials.

In this case, a total of 137 sandwiches were sold (22 ham on white bread + 24 ham on wheat bread + 21 turkey on white bread + 22 turkey on wheat bread + 25 tuna on white bread + 23 tuna on wheat bread). Out of these, 23 were tuna on wheat bread.

The experimental probability of the next sandwich being a tuna on wheat bread is therefore 23/137, or approximately 0.168, if this same pattern continues.

Answer: 12.5m(2+m)

Step-by-step explanation:

the weight of train A is 334 tons, and the weight of train B is 20 tons.

Let's denote:

- The weight of train A as x tons,

- The weight of train B as y tons.

We're given two pieces of information:

1. The total weight of both trains is 354 tons: [tex]\( x + y = 354 \)[/tex].

2. Train A is heavier than train B by 314 tons: [tex]\( x = y + 314 \).[/tex]

Now, we can set up a system of equations using these two pieces of information and solve for x and y.

From equation (2), we have:

[tex]\[ x = y + 314 \][/tex]

We can substitute this expression for x into equation (1):

[tex]\[ (y + 314) + y = 354 \][/tex]

Now, let's solve for y:

[tex]\[ 2y + 314 = 354 \][/tex]

[tex]\[ 2y = 354 - 314 \][/tex]

[tex]\[ 2y = 40 \][/tex]

[tex]\[ y = \frac{40}{2} \][/tex]

[tex]\[ y = 20 \][/tex]

Now that we have found the weight of train B, we can substitute this value into equation (2) to find the weight of train A:

[tex]\[ x = 20 + 314 \][/tex]

[tex]\[ x = 334 \][/tex]

So, the weight of train A is 334 tons, and the weight of train B is 20 tons.

Answer:

option D. 126 cm

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Triangles PQR and XYZ are similar by AA Similarity Theorem

so

[tex]\frac{XY}{PQ}=\frac{YZ}{QR}=\frac{XZ}{PR}[/tex]

Let

z ---> the scale factor

[tex]z=\frac{XY}{PQ}[/tex]

substitute the given values

[tex]z=\frac{30}{5}=6[/tex]

step 2

Find the perimeter of triangle XYZ

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z ----> the scale factor

p_1 ----> the perimeter of triangle XYZ

p_2 ---> the perimeter of triangle PQR

so

[tex]z=\frac{p_1}{p_2}[/tex]

The perimeter of triangle PQR is

[tex]p_2=5+10+6=21\ cm[/tex]

we have

[tex]z=6\\p_2=21\ cm[/tex]

substitute

[tex]6=\frac{p_1}{21}[/tex]

[tex]p_1=6(21)=126\ cm[/tex]

therefore

The perimeter of triangle XYZ is 126 cm

The Perimeter of ΔXYZ that is similar to ΔPQR is: 126 cm.

The corresponding side lengths of similar figures are proportional, that is, their ratios are equal.

Given that ΔPQR and ΔXYZ are similar, we would have the following ratios:

PQ/XY = PR/XZ = QR/YZ

Find XZ and YZ using their ratios:

PQ/XY = PR/XZ

Substitute

5/30 = 6/XZ

XZ = (6 × 30)/5

XZ = 36 cm

5/30 = 10/YZ

YZ = (10 × 30)/5

YZ = 60 cm

Perimeter of ΔXYZ = XY + XZ + YZ

Perimeter of ΔXYZ = 30 + 36 + 60

Perimeter of ΔXYZ = 126 cm.

Answer:

Alex is wrong in calculating his dive distance.

Actual distance of his Dive is 30 feet.

Step-by-step explanation:

Given:

Distance from where he dive from = 15 feet

Distance he reached after dive = 15 feet

Also Given:

Alex says that the two distances are opposites,

Also Total distance of dive according to Alex = 15 +-15 =0 feet

Solution:

Now we know that;

The diving board is 15 feet above the water level, and then he reached 15 deep in the water, but here it is important to know that even he is above the surface of the water he is diving in the water and then he reached 15 deep in the water.

So the two distances are in the same direction.

From above scenario we can say that

Total Distance of dive will be = 15 +15 =30 feet.

Hence We can say that Alex is wrong in calculating his dive distance. Actual Dive distance is 30 feet.

Answer:

sin(71°)

Step-by-step explanation:

Sine lags behind cosine by 90°

cos(19°) = sin(90° - 19°)

= sin(71°)

Option B is correct, the surface area of the ramp will be 210 square cm.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Let h be the height and b be the base of the triangle. Let L₁, L₂, and L₃ be the length and W be the width of the rectangle.

Then the surface area of the triangular prism will be given as,

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = (h x b) + (L₁ + L₂ + L₃) x W

Sean must determine how much paint he will use to cover all of the edges of his ramp.

The surface area of the ramp is calculated as,

SA = (8 x 6) + (5 + 6 + 7) x 9

SA = 48 + 18 x 9

SA = 48 + 162

SA = 210 square cm

Hence, the surface area of the ramp will be 210 square cm. Then the correct option is B.

To find the solutions to the equation y = 2x - 3, substitute different x-values and solve for y.

The given equation is y = 2x - 3.

To find the ordered pairs that are solutions to this equation, substitute different x-values and solve for y.

Let's take the first ordered pair (294.5, 61) as an example:

Therefore, the ordered pair (294.5, 61) is not a solution to the equation y = 2x - 3.

Repeat the same process for the other two ordered pairs to determine if they are solutions to the equation.

The number of five- and ten-dollar bills that Salim has are; 6 and 3

We are given two equations;

x + y = 9 - - - - (eq 1)

5x + 10y = 60 - - - (eq 2)

Where;

x represents the number of five-dollar bills.

y represents the number of ten-dollar bills.

Making x the subject in eq 1 gives;

x = 9 - y

Put 9 - y for x in eq 2 to get;

5(9 - y) + 10y = 60

45 - 5y + 10y = 60

5y + 45 = 60

5y = 60 - 45

5y = 15

Answer:

The page numbers are 46 and 47.

Step-by-step explanation:

Given:

Qasim hussain opened his account book. He observed that the sum of page numbers of the two pages in front of him is 93.

Now, to find the page numbers.

Let the first page number be [tex]x.[/tex]

And the other page number be [tex]x+1.[/tex]

As, given he observed that the sum of page numbers of the two pages in front of him is 93.

According to question:

[tex]x+(x+1)=93[/tex]

[tex]x+x+1=93\\2x+1=93[/tex]

Subtracting both sides by 1 we get:

[tex]2x=92[/tex]

Dividing both sides by 2 we get:

[tex]x=46.[/tex]

So, the first page number = 46.

And the other page number = [tex]x+1=46+1=47.[/tex]

Therefore, the page numbers are 46 and 47.

Owen's songs were played on 3 movies and on 7 commercials.

Step-by-step explanation:

System of Equations

Let's call C the number of commercials on which Owen's songs were played and M the number of movies on which Owen's songs were played. We know Owen's songs were played on 4 more commercials than movies, it can be expressed as

[tex]C=M+4[/tex]

Owen will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie, so his total earnings are

[tex]140M+50C=770[/tex]

We have a system of linear equations that can be easily solved by using the formula for C in the above equation

[tex]140M+50(M+4)=770[/tex]

The total cost of a meal with an 18% tip is calculated by converting the tip to a decimal (0.18), multiplying it by the meal cost, and adding it to the original cost. For a $72 meal, the total with tip would be $84.96.

To calculate the total cost of a meal including an 18% tip, you first convert the tip percentage to a decimal by dividing by 100. For an 18% tip, this gives you 0.18. Then, multiply the cost of the meal by this decimal to find the amount of the tip. Finally, add the tip to the original cost of the meal to find the total cost including the tip.

Example Calculation

If the cost of the meal is $72, the tip would be calculated as follows:

Therefore, the total cost of the meal with an 18% tip would be $84.96.

Answer:

A=41

B=20

C=8

D=3

Step-by-step explanation:

You need to first of all fill the intersection (yellow region). This is the number of people who use both.

This means B=20

Region A is those who use F only. So you must subtract the number who use both.

This means that A=61-20=41

Region C is those who use G+ only.

This means C=28-20=8

Now A+B+C+D=72

This implies that:

41+20+8+D=72

69+D=72

D=72-69

D=3

The first investment can be shown as T=500*1.05^2 which is $551.25

The second investment can be shown as T=500*e^(0.03*12*2) which is $1027.22

So the second investment is better
