Answer:

2:12 or 1:6

Step-by-step explanation:

there are 12 students. you and your friend are 2 of the 12. so it would be a 2:12 chance that you or your friend would get picked. unless if you simplify which then it would be a 1:6 chance that either of you would get picked.

Answer:

x = 245 and x = 20

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the interior angles and equate to 540

25 + 112 + 100 + 58 + x = 540

295 + x = 540 ( subtract 295 from both sides )

x = 245

---------------------------------------------------------------

5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540

25x + 40 = 540 ( subtract 40 from both sides )

25x = 500 ( divide both sides by 25 )

x = 20

Answer:

A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic

Step-by-step explanation:

Function: Every domain (x-value) has only one range (y-value)

The other choices had an x-value that had more than one y-value, which makes only this one a function.

Answer:

1 to 6

Step-by-step explanation:

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Step-by-step explanation:

x/12=-2

12         x                               I did 12 times x/12 to get the x alone.

Do 12 times -2 too,

so..    12 x-2=-24

x= -24

Answer:

21.248

Step-by-step explanation:

The required value of decimal value 21.24833 to three decimal points is 21.248.

Given that,
21.24833, to round this number to 3 decimal places.

In mathematics, it deals with numbers of operations according to the statements.

Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

In the question, a decimal value is given, 21.2488, and asked to round this off to 3 decimal places.

When rounding off the number, we check the preceding value neared to which zero either to 0 or 10. if it is near 0 the value before is round off value and the preceding value is near 10 then the value before the proceeding value is increased by 1.

In our case, the value after the third decimal is 3 which is near 0 so nothing will change and the value terminates as it is after 3 decimal points i.e 21.248.

Thus, the required value of decimal value 21.24833 to three decimal points is 21.248.

Answer:Bill gets £171

Step-by-step explanation:

Total Money shared = £399

The ratio of the amount Ann gets to bill gets is 2:9 Chloe and Dave get 2.5 times the amount Ann gets can be written as  

Ann : Bill   :     Chloe :   Dave

      2 : 9    : 2.5 x Ann :   2.5 x Ann

Let the amount of money

Ann gets be x

so that Bill gets 4.5x

Chloe = 2.5x

Dave = 2.5x  

So that the expression to calculate each amount gooten will be  

x + 4.5x + 2.5x + 2.5x = 399

10.5x = 399

x = 399/10.5

x=38

Therefore, Ann gets  = £38

Bill gets =4.5 x=   4.5 x £38 = £171

Chloe gets=2.5x =2.5 x £38  = £95

Dave gets=2.5x =2.5 x £38  = £95

a. [tex]5 + (-3x) = -4[/tex]

b. [tex]5 + (-3x) = 4[/tex]

c. [tex]5 + (-3x) = 14[/tex]

Step-by-step explanation:

Given

[tex]5 + (-3x)[/tex]

Required

Evaluate

(a) x = 3

[tex]5 + (-3x) = 5 + (-3*3)[/tex]

[tex]5 + (-3x) = 5 + (-9)[/tex]

Remove bracket

[tex]5 + (-3x) = 5 -9[/tex]

[tex]5 + (-3x) = -4[/tex]

(b) x = 1/3

[tex]5 + (-3x) = 5 + (-3*1/3)[/tex]

[tex]5 + (-3x) = 5 + (-1)[/tex]

Remove bracket

[tex]5 + (-3x) = 5 -1[/tex]

[tex]5 + (-3x) = 4[/tex]

(c) x = -3

[tex]5 + (-3x) = 5 + (-3*-3)[/tex]

[tex]5 + (-3x) = 5 + (9)[/tex]

[tex]5 + (-3x) = 14[/tex]

Answer:

65 square units

Step-by-step explanation:

The area of a triangle is: height times base divided by two.

So the area of one of the triangles is 10 square units.

multiply this times 4 to get the total area of the triangles

then add the area of the square which is 5 times 5

25 plus 40 = 65 square units

The retail price of the skateboard = [tex] \color{hotpink}\boxed{\bold{\tt\bold{\$110}}}[/tex]

Given :

▪︎Cost price of a skateboard in a sports shop = $80

▪︎Percentage of markup in the price of the skateboard = 37.5%

Which means :

The retail price of the skateboard :

= Intial price of skateboard + 37.5% of it's initial price

[tex] = \tt80 + 37.5\% \: of \: 80[/tex]

[tex] =\tt 80 + \frac{37.5}{100} \times 80[/tex]

[tex] =\tt 80 + \frac{37.5 \times 80}{100} [/tex]

[tex] = \tt80 + \frac{3000}{100} [/tex]

[tex] =\tt 80 + 30[/tex]

[tex]\color{plum} = \tt\bold{\$110}[/tex]

Therefore, the retail price of the skateboard = $110
