A square has sides of length 8 inches. To the nearest tenth of an inch, what is the length of its diagonal?

Answer:6.71

Answer:

The stem and leaf plot is not shown, so I will answer the question in a general way.

Suppose you have the following stem and leaf plot

I 2 I 0 5 8

I 3 I 4 4 7 8

I 4 I 0

Then, the data is: 20, 25, 28, 34, 34, 37, 38, 40. In consequence, one department stores has exactly 37 pairs of glasses. But if your stem and leaf plot is:

I 2 I 0 5 8

I 3 I 7 7 7 8

I 4 I 0

then, three department stores have 37 pairs of glasses, and none of them have 34 pairs of glasses.

Step-by-step explanation:

Use FOIL method

(2k + 1) (k - 4) = 2k*k + 2k*(-4) + 1*k + 1*(-4)

                      = 2k² - 8k + k - 4   {add the like terms}

                    = 2k² - 7k - 4

Answer:

2k²-7k-4

Step-by-step explanation:

(2k + 1 ) (k - 4)

2k * k - 2k * 4 + k - 4

2k² - 8k + k - 4

2k² - 7k - 4

Answer:

This is an example of independent probability.

Step-by-step explanation:

Independent events are not affected by previous events, just like the outcome of rolling a dice is not effected by the previous outcome. (The dice has no memory of any kind, what so ever!).

When two events are said to be independent of each other, meaning the probability that one event occurs in no way affects the probability of the other event occurring. Another example of an independent event is when you flip a coin. (The coin has no memory of any kind, what so ever!).

Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:

P(A and B) = P(A) · P(B)

The dice was cast 10 times. In three occasions a 5 came out, and in 7 occasions another outcome occurred. The probability of the outcome of exactly 3 times a 5 in 10 casts, can be calculated as:

P(5) =(1 / 6)^3 + (5 / 6)^7

P(5) = 0.28

P(5) = .3

Answer:

51.25

Step-by-step explanation:

Do you mean the surface area of the pyramid?

Base = [tex]2.5^2[/tex] = 6.25

Triangles = [tex]\frac{9 * 2.5 * 4}{2}[/tex]

9 * 2.5 * 2 = 45

45 + 6.25 = 51.25

Answer:

x = 17°, m∠ A = 114°

Step-by-step explanation:

We can tell that these pair of angles are corresponding, provided;

Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,

m∠ A = m∠ B ⇒ Substitute values of A and B,

6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,

3x + 12 = 63 ⇒ Subtract 12 on either side of equation,

3x = 51 ⇒ Divide either side by 3,

x = 17 ⇒ Substitute value of x to solve for m∠ A,

m∠ A = 6 * ( 17 ) + 12,

m∠ A = 102 + 12,

m∠ A = 114

Solution; x = 17°, m∠ A = 114°

Answer:

x = 17, ∠A = 114°

Step-by-step explanation:

I'm 8 years old and I know how to do this.

6x + 12 = 3x + 63

3x + 12 = 63

3x = 51

x = 17

6(17) + 12

102 + 12 = 114

Answer:

1176 cm3

Step-by-step explanation:

The probability of getting exactly 7 tails is 1/32.

The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.

In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.

The number of times of toss of a fair coin is given as 8.

The probability of getting head is 1/2.

And, the probability of getting tail is 1/2.

The given problem can be solved using the expression of binomial distribution as ⁿCₓpˣqⁿ⁻ˣ, where p and q are the probability of success and failure respectively, n is the total number of trials and x is the favorable number of trials.

In order to find the probability of getting tail 7 times out of 8, the binomial distribution can be used as,

P(exact 7 tails) = ⁸C₇(1/2)⁷(1/2)¹

                        = 8 × 1/128 × 1/2

                        = 1/32

Hence, the probability of getting exactly 7 tails is 1/32.

Answer:

y= 200/6x + 100

Step-by-step explanation:

Process of elimination it can't be y= 2/3x + 100 or y = 2/3x because then for x = 12 y would equal 108, but it was closer to 200. That means it had to be one of the other two, the one without the +100 would also end up being too little.

Answer:

384 cubic meters

Step-by-step explanation:

Think of it as two rectangles on top of each other and then add the two volumes.

Volume is l*w*h

So for the bottom rectangle: (8) (12) (2) = 192 cubic meters

And for the top rectangle: (4)(6)(8) = 192 cubic meters

It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.

Then you add them together.

192+192 = 384 cubic meters

Answer:

D. 8

E. 130

Step-by-step explanation:

D. set the equations equal to each other than solve and try to get one side with the x's.

10x+50=5x+90

-5x          -5x

5x+50=90

    -50   -50

5x=40

divide 5 on both sides

x=8

E. plug in 8 as x for either equation

=5(8)+90

=40+90

=130

=10(8)+50

=80+50

=130
