Answer: D. 0.860

Step-by-step explanation:

In the table we can see that he rolled the cube 1000 times, and he recorded that 140 of those times he rolled a 5.

Then, the probability of rolling a 5 will be equal to:

P1 = 140/1000 = 0.14

Now, the probabilty of NOT rolling a 5, is equal to the rest of the probabilities, this is:

P2 = 1 - 0.14 = 0.86

then the correct option is D

Answer:

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

[tex]x^{2} +x^{2}[/tex] = 72

2[tex]x^{2}[/tex] = 72. Divide both sides by 2

[tex]x^{2}[/tex] = 36.  Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 +[tex]\sqrt{72}[/tex] = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397 [tex]cm^{2}[/tex]

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4 [tex]cm^{3}[/tex]

Final answer:

The surface area of the triangular prism can be calculated by finding the areas of the two triangular bases and the three rectangular sides. After calculations, the total surface area of the prism is found to be 2304 square centimeters.

Explanation:

The question asks us to find the surface area of a triangular prism whose base is an isosceles right triangle with a hypotenuse of √72 centimeters and a height of 7 centimeters. We'll use various formulas for geometry, area, and volume to solve this problem.

First, we need to find the legs of the isosceles right triangle which form the base of the prism. Since it is a right triangle, and the legs (a) are equal, we can use Pythagoras' theorem where [tex]a^2 + a^2 = (72)^2[/tex]

Solving this gives us each leg as 36 cm.

The area of the base triangle is then found using 1/2 × base × height, which gives us-

1/2 × 36 × 36 = 648 square centimeters

The prism has two such triangular bases, so their combined area is 2 × 648 = 1296 square centimeters.

For the three rectangular sides, we calculate their areas by using the formula for the area of a rectangle (length × width). Each side has a length of 7 cm (the height of the prism). The widths are equal to the sides of the triangular base: 36 cm, 36 cm, and √(362 + 362) = √2592 = 72 cm. Thus, the total area of these sides is-

2(36 × 7) + (72 × 7) = 504 + 504 = 1008 square centimeters.

The total surface area of the prism is the sum of the areas of the bases and the rectangular sides, which is 1296 + 1008 = 2304 square centimeters.

Final answer:

To find the value that goes in the empty cell, we need to multiply each value of x by 5. So, when x = -1, f(x) = 5*(-1) = -5. Therefore, the value that goes in the empty cell is -5.

Explanation:

The table represents the function f(x) = 5x. In the first column, we have the values of x, which are -1, 0, 1, and 2. In the second column, we have the values of f(x), which are blank, 0, 5, and 10. To find the value that goes in the empty cell, we need to multiply each value of x by 5. So, when x = -1, f(x) = 5*(-1) = -5. Therefore, the value that goes in the empty cell is -5.

Answer:

71 and -35

Step-by-step explanation:

so with this we can set up a system of equations

x+y=36

and

x-y=106

now we can add these equations together to eliminate y

x+y=36 plus

x-y=106 equals

2x=142

divide both sides by 2

x=71

now we can plug that in

71+y=36

subtract 71 from both sides

y=-35

Answer:

-71 and

35

Step-by-step explanation:

Let the numbers be x and y

x + y = -36

x = y - 106

Substitute y - 106 or x in the first equation

We have

x + y = -36

y - 106 + y = -36

y + y - 106 = -36

2y - 106 = -36

Add 106 to both sides to eliminate -106 on the left side

2y - 106 + 106 = -36 + 106

2y = 70

Divide both sides by 2

2y/2 = 70/2

y = 35

Substitute 35 for y in either equation to get x

Using the second equation, we have

x = y - 106

x = 35 - 106

x = -71

The numbers are 35 and -71

Check

x + y = -36

-71 + 35 = -36

-36 = -36

25 % of the water had evaporated.

Answer:

20%

Step-by-step explanation:

Since the total amount of water is 2.5 million

And 2 million evaporated,

To determine the amount left,it will be total amount- evaporated

2.5-2=0.5

To determine the% of evaporated water

It will be evaporated/total amount ×100

0.5/2.5 × 100

50/2.5

20%

So the percentage of the evaporated water is 20%

The equivalent of the expression | - 12 + 3 | is 9 because after simplifying the expression inside the absolute value parentheses, -12 + 3 is -9 and the absolute value of -9 is 9.

The student is asking for the equivalent of the absolute value expression | − 12 + 3 |. To solve this, we have to simplify the expression inside the absolute value parentheses first, which means performing the operation −12 + 3. This results in −9, because when you add a positive number to a negative one, you effectively subtract the smaller number from the larger one, but keep the sign of the larger number.

The absolute value of a number is the distance of that number from zero on a number line, regardless of the direction, so the absolute value of −9 is 9. Therefore, the expression | − 12 + 3 | is equivalent to 9.

BRAINLIEST PLZ I ANSWERED FIRST

Answer:

3/7

Step-by-step explanation:

Probability is essentially (# ways specific event can occur) / (# ways any general event can occur).

In this case, the specific event is getting a human avatar. Since there are 3 humans to choose from, the number of ways this specific event can occur is 3 ways. The general event is just choosing any avatar. Since there are a total of 3 + 4 = 7 characters to select from, the number of ways this general event can occur is 7.

Putting it together, we have the probability of choosing a human character as 3/7.

Ms. Joseph saves money for 12 weeks, starting with $1 and increasing the amount by $1 each week. By the 12th week, she adds $12. Therefore, she saves money for a total of 12 weeks.

To determine how many weeks Ms. Joseph is saving money, we need to look at the pattern of her savings. Each week, she adds one more dollar than the previous week:

We can see that this is an arithmetic sequence where the first term (a) is $1 and the common difference (d) is $1. The nth term of an arithmetic sequence can be found using the formula: aₙ = a + (n-1)d.

For 12 weeks, the amount saved each week would be: a₁₂= 1 + (12-1) ×1 = 12. Ms. Joseph adds $12 in the 12th week. Finally, the total weeks she saves money is 12 weeks.

https://brainly.com/question/12468032

Final answer:

To find the number of different arrangements of president, vice-president, and secretary in a club of 11 members, we use the concept of permutations. Using the formula for permutations of distinct objects, we calculate P(11,3) = 990. Thus, there are 990 different arrangements possible.

Explanation:

To find the number of different arrangements of president, vice-president, and secretary, we can use the concept of permutations. Since the positions have different roles and can only be assigned to one person each, we use permutations. The number of permutations can be found using the formula for permutations of distinct objects: P(n,r) = n! / (n-r)!.

In this case, we have 11 members and need to assign them to 3 different positions (president, vice-president, and secretary). So, the number of arrangements is P(11,3) = 11! / (11-3)! = 11! / 8! = 11 x 10 x 9 = 990.

Therefore, there are 990 different arrangements of president, vice-president, and secretary possible.

To make ½ of a cake recipe that calls for 2 and ¼ cups of cake mix, you need to divide that amount by 2, resulting in 1 and 1/8 cups of cake mix needed.

Explanation:

To find out how many cups of cake mix you need to make ½ of the recipe, start with the original amount of cake mix required by the recipe, which is 2 and ¼ cups. Since you're making half of the recipe, you'd divide this amount by 2. Perform the division: (2 + ¼) ÷ 2 = 1 and ¹⁸ cups. Thus, you will need 1 and ¹⁸ cups of cake mix for half the recipe.

Here's the step-by-step calculation:

Convert the mixed number to an improper fraction: 2 and ¼ cups = 9/4 cups.

Divide the improper fraction by 2 to make half of the recipe: (9/4) ÷ 2 = 9/4 × 1/2 = 9/8.

Convert the improper fraction back to a mixed number: 9/8 = 1 and 1/8 cups.

So, you need 1 and 1/8 cups of cake mix to make half of the recipe.
