Step-by-step explanation:

If you get a normal ruler it will be one foot total. You add the bigger measurements twice because they're an inch. Then you add half of those measures. It will be numbered 1, 2, 3... so on . In other words, the longer lines are inches and the shorter ones are centimeters.

Answer:

So here's a step by step

1: Pick up your ruler.

2: Make sure the ruler is not broken or cracked.

3: Find the thing you want to measure.

4: Put the ruler against the object.

5: Make sure the 0 on the ruler is right on the side of what your measuring.

6: When all that is done find the 2 on the ruler that is 2 inches

7: Then find the 1/2 mark next to the 2 that is 2 1/2 inches.

Answer:

i think Its 5/8

Step-by-step explanation:

this one is tricky for me at least

Answer:

a)

The possible values are 0, 1, 2 and 3.

The probability mass function of X is:

P(X = 0) = 0.125

P(X = 1) = 0.375

P(X = 2) = 0.375

P(X = 3) = 0.125

b)

[tex]P(X \geq 1) = 0.875[/tex], [tex]P(X > 1) = 0.5[/tex]

c) E(X) = 1.5, Var(X) = 0.75

Step-by-step explanation:

For it time the coin is flipped, there are only two possible outcomes. Either it comes up heads, or it comes up tails. Each toss is independent of other tosses. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The variance of the binomial distribution is:

[tex]V(X) = np(1-p)[/tex]

A fair coin is flipped three times.

This means that [tex]n = 3[/tex]

Fair coin means that it is equally as likely to be heads or tails, so [tex]p = \frac{1}{2} = 0.5[/tex]

a) Give both the possible values and probability mass function of X.

The possible values are from 0 to n, so 0, 1, 2 and 3.

The probability mass function is the probability of each outcome. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]

[tex]P(X = 1) = C_{3,1}.(0.5)^{1}.(0.5)^{2} = 0.375[/tex]

[tex]P(X = 2) = C_{3,2}.(0.5)^{2}.(0.5)^{1} = 0.375[/tex]

[tex]P(X = 3) = C_{3,0}.(0.5)^{3}.(0.5)^{0} = 0.125[/tex]

(b) Find P(X ≥ 1) and P(X > 1).

[tex]P(X \geq 1) = P(X = 1) + P(X = 2) + P(X = 3) = 0.375 + 0.375 + 0.125 = 0.875[/tex]

[tex]P(X > 1) = P(X = 2) + P(X = 3) = 0.375 + 0.125 = 0.5[/tex]

(c) Compute E[X] and Var(X).

[tex]E(X) = np = 3*0.5 = 1.5[/tex]

[tex]Var(X) = np(1-p) = 3*0.5*0.5 = 0.75[/tex]

Answer:

486cm^2

Step-by-step explanation:

cube volume: 729cm^3

cube faces count: 6

How you calculate square area:

s(cm) * s(cm) or just s^2(cm^2)

s = side length

If you want to find out the side length of a cube by its volume. Then simply just remove the ^3 by taking the cubic root (also written ^(1/3))

729^(1/3) = 9

then just calculate the area like i showed earlier:

(9cm)^2 = 81cm^2

But that is only one side of a cube's 6 sides, so multiply by 6:

81cm^2 * 6 = 486cm^2

Hope i could help :D

We have to simplify the given expression.

Consider the given expression (3x − 5) − (4x + 6).

Remove Parentheses ,

we have,

(3x − 5) − (4x + 6) = 3x - 5 - 4x -6

Combining like terms, we have,

LIKE TERMS are terms having same variable with same degree.

here 3x and -4x are like term  and -5 and -6 are like terms,

Simplify, we have,

= 3x - 4x - 5 - 6

= -x - 11

Thus, the given expression (3x − 5) − (4x + 6) =  -x - 11.

Answer:

  49°

Step-by-step explanation:

Angles A and C are complementary, so we have ...

  (3x -7) +(2x +17) = 90

  5x = 80 . . . . . . . . . . . . . subtract 10

  x = 16 . . . . . . . . . divide by 5

Then the measure of angle C is ...

  ∠C = 2x +17 = 2(16) +17

  ∠C = 49

Given:

One of the legs of a right triangle is 9 cm.

The area of the triangle is 225 cm².

To find:

The length of the other leg.

Solution:

The area of a triangle is

[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]

The area of a right triangle is

[tex]Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)[/tex]

Let x be the length of other leg.

[tex]225=\dfrac{1}{2}\times (9)\times (x)[/tex]

[tex]2\times 225=9x[/tex]

[tex]\dfrac{450}{9}=x[/tex]

[tex]50=x[/tex]

Therefore, the length of the other leg is 50 cm.

The lengths of sides of the parallelogram are 71 inches and 51 inches. Hence, option (C) is correct.

A unique variety of quadrilateral called parallelogram, a parallelogram has both pairs of its opposite sides parallel and equal.

Let sides of the parallelogram are a and b.

The perimeter of parallelogram  = 2(a+b)

Given that,

The perimeter of parallelogram = 244

implies that,

2(a+b) = 244

a+b = 122       (1)

Also, the difference of sides is 20 inches,

implies that,

a-b = 20       (2)

By solving equation (1) and (2),

a = 71 inches,

b = 51 inches.

The lengths of sides of the parallelogram are 71 inches and 51 inches.
