Answer:

0.0228

Step-by-step explanation:

Let us assume that the mean (μ) = 2 and the standard deviation (σ) = 0.5

Z score is a standard score used to measure the number of standard deviations by which the raw score (x) is above or below the mean. It is given by the equation:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

For x > 3

[tex]z=\frac{x-\mu}{\sigma} =\frac{3-2}{0.5}=2[/tex]

From the normal distribution table, P(x > 3) = P(z > 2) = 1 -  P(z < 2) = 1 - 0.9772 = 0.0228

I literally guessed some random numbers and got it right. You can trust me tho. It’s right.

Answer: I think it is B

Answer:

A,D,F

A is in Quadrant I.

D is in Quadrant III.

F is on the x-axis.

Step-by-step explanation:

got this right..... I did this like 3 months ago so I just answered this

hope this helps:)

The statements A is in Quadrant I is true, D is in Quadrant III is true and F is on the x axis is true.

Coordinate geometry is defined as the study of geometry using the coordinate points.

On a coordinate plane, point A is (2, 3),

point B is (3, 2),

point C is (negative 2, 2),

point D is (negative 3, negative 3),

point E is (0, 3),

point F is (2, 0), and

point G is (0, 0).

A coordinate geometry has 4 quadrants, in the first Quadrant the x and y axis values are positive.

In second quadrant the coordinates are (-x, y)

In third quadrant the coordinates are (-x, -y)

In fourth quadrant the coordinates are (x, y)

A is in Quadrant I is true

D is in Quadrant III is true

F is on the x axis is true.

Hence, the statements A is in Quadrant I is true, D is in Quadrant III is true and F is on the x axis is true.

Answer:

You didn't give the geometric sequence in question.

But to find the nth term of a geometric sequence, use the formula

Sn = ar^(n - 1)

Where a is the first term of the sequence

r is the common ratio of the sequence.

Example: To find the nth term of the geometric sequence

1/2, 1/4, 1/8, 1/16, ...

Here, a = 1/2

r = 1/4 ÷ 1/2 = 1/8 ÷ 1/4 = 1/16 ÷ 1/8 = 1/2.

Sn = (1/2)(1/2)^( n - 1)

Apply this method to the sequence you were given, it will be helpful.

Answer:

24.

Step-by-step explanation:

We can use the factorial function to find the number of unique arrangements in a word.

There are 4 unique characters in 'OPAL'. As such, 4! = 24.

In the case that there were repeating characters, such as 'OPALA', then we would divide by the factorial of the number of repeating letters. That looks something like this:

[tex]\frac{5!}{2!} = 60[/tex]

The sum of the digits of a two-digit numeral is 8. If the digits are reversed, the new number is 18 greater than the original number. How do you find the original numeral?

Answer:

The original number is 10a + b  = 10 × 3 + 5  = 35

Step-by-step explanation:

Let

the number = ab

a occupies the tens place while b occupies the unit place. Therefore,

10a + b

The sum of the digits of two-digits numeral

a + b = 8..........(i)

If the digits are reversed. The reverse digit will be 10b + a. The new number is 18 greater than the original number.

Therefore,

10b + a = 18 + 10a + b

10b - b + a - 10a = 18

9b - 9a = 18

divide both sides by 9

b - a = 2...............(ii)

a + b = 8..........(i)

b - a = 2...............(ii)

b = 2 + a from equation (ii)

Insert the value of b in equation (i)

a + (2 + a) = 8

2a + 2 = 8

2a = 6

a = 6/2

a = 3

Insert the value of a in equation(ii)

b - 3 = 2

b = 2 + 3

b = 5

The original number is 10a + b  = 10 × 3 + 5  = 35

Answer:

Yes, this is a right triangle.

Step-by-step explanation:

The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).

Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:

10² = 100

49.5² = 2450.25

100 + 2450.25 = 2550.25

50.5² = 2550.25

Since 10² + 49.5² equals 50.5², we know that this is a right triangle.

Thus, yes, this is a right triangle.

Answer:

326.6 m^2

to nearest tenth.

Step-by-step explanation:

The radius of the flower bed = 1/2 * 22 = 11m

The radius of the whole area included the sidewalk = 11 + 4 = 15 m

So the area of the sidewalk = area of the whole - area of flower bed

= 3.14 * 15^2 - 3.14* 11^2

= 326.6 m^2.

Answer:

5/33

Step-by-step explanation:

five apples and seven peaches = 12 total

P( apple) = number of apples / total

               = 5/12

No replacement since you ate it

four apples and seven peaches = 11 total

P( peach) = number of peach / total

               = 4/11

P(apple, no replacement, peach) = 5/12 * 4/11 = 5/33

Answer: g = 10

Step-by-step explanation: 8g + 3 = –6g + 13g + 13

                                             8g + 3 = (–6g + 13g) + (13)

                                             8g + 3 = 7g + 13

                                             8g + 3 - 7g = 7g + 13 - 7g

                                             g + 3 = 13

                                             g + 3 - 3 = 13 - 3

                                             g = 10                                            

Answer:

[tex]8g + 3 = -6g + 13g + 13 : g = 10[/tex]

Step-by-step explanation:

[tex]8g+3=-6g+13g+13[/tex]

Add similar elements: [tex]-6g+13g=7g[/tex]

[tex]8g+3=7g+13[/tex]

Subtract [tex]3[/tex] from both sides:

[tex]8g+3-3=7g+13-3[/tex]

Simplify:

[tex]8g=7g+10[/tex]

Subtract [tex]7g[/tex] from both sides:

[tex]8g-7g=7g+10-7g[/tex]

Simplify:

[tex]g=10[/tex]
