Answer:

3916 hello's were said

Explanation:

(n/2)(n-1)

insert n = 89

(89/2)(89-1)

(44.5)(88)

3916 hello's

Answer:

3916 hellos

Step-by-step explanation:

That is the number of combinations of 2 from 89

= 89! / (89-2)! 2!

= 89! / 87! 2!

= 89*88 / 2

= 3916.

The probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

For given question,

We have been given five number cards.

Two of the five cards are picked at random.

Using combination formula the possible number of outcomes would be,

[tex]^5C_2\\\\=\frac{5!}{2!(5-2)!} \\\\=10[/tex]

So, n(S) = 10

Let event A : the total of the two numbers is more than 32

A = {(19, 14), (19, 22), (13, 22), (14, 22)}

So, n(A) = 4

Using the formula for probability,

[tex]\Rightarrow P(A)=\frac{n(A)}{n(S)} \\\\\Rightarrow P(A)=\frac{4}{10}\\\\\Rightarrow P(A)=\frac{2}{5}[/tex]

Therefore, the probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

Answer:

Step-by-step explanation:

the area of a triangle is area= 1/2 x base x height. ( half multiply by base multiply by height)

so plug in 22 for area 22=1/2 x 4 x height

22/2=11

11 is the length

Answer: B. 9

Step-by-step explanation:

First, find the median of the data set. This set has an even number of points, so find the average between the two middle points: 18 and 19. 18+19 = 37. 37/2 = 18.5. The median is 18.5.

Now, to find the lower quartile, find the median of the lower half of the data set {11, 12, 14, 15, 18}. The number in the middle is 14. The lower quartile is 14.

To find the upper quartile, find the median of the upper half of the data set {19, 21, 23, 25, 55}. The number in the middle is 23. The upper quartile is 23.

To find the interquartile range, subtract the lower quartile from the upper quartile. 23-14 = 9. The interquartile range is 9.

Step-by-step explanation:

Total money does the shop receive is  0.12 Pound

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

According to the question

A shop sells apples and oranges in the ratio 5:2

Let constant multiple of the ratio as a

Now,

Apples = 5a

Oranges = 2a

Total pieces of fruit sell = 35

i.e

5a + 2a = 35

7a = 35

a = 5

Therefore,

Apples = 5*5 = 25

Oranges = 2*5 = 10

Now ,

Shop sells apples at =  30p

Shop sells oranges at = 40p

Total money  the shop receive = 30 * 25 + 40 * 10

                                                    = 1150 p

Paisa to Indian rupee :               100p = ₹1

                                                    =  ₹11.50

Now, Indian rupee to pounds :

1 Indian Rupee equals 0.011 Pound (according to current market value)

₹11.50  is equal to 0.12 Pound

Hence, Total money does the shop receive is  0.12 Pound .

Answer: 972π in³

Step-by-step explanation:

  We will use the proper formula to solve for the volume of the sphere.

-> The radius (r) is half the diameter. 18 in / 2 = 9 in

V = [tex]\frac{4}{3}[/tex]πr³

V = [tex]\frac{4}{3}[/tex]π(9)³

V = [tex]\frac{4}{3}[/tex] * (9)³ * π

V = 972π in³

   The volume is 972π in³

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

Answer:

8

Step-by-step explanation:

2 times 4 is 8

Step-by-step explanation:

remember, when multiplying the same base with different exponents, we add the exponents.

when putting exponents to the power of exponents, we multiply the exponents (as simplified shortcut of all the additions we would actually have to do).

((-3)²)⁴ = (-3)⁸

in "slow motion" :

((-3)²)⁴ = (-3)²×(-3)²×(-3)²×(-3)² = (-3)^(2+2+2+2) = (-3)⁸

(-3)² = 9

9⁴ = 6561

(-3)⁸ = 6561

Answer:

(2x+1)(1) = 84. 2x+1= 84. 2x = 83.

Step-by-step explanation:

Answer:

The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.

1) Rearrange terms

3 + 5m = 5m + 3

5m + 3 = 5m + 3

2) Subtract 3 from both sides

5m + 3 = 5m + 3

5m + 3 - 3 = 5m + 3 - 3

3) Simplify

- Subtract the numbers

5m + 3 - 3 = 5m +  3 - 3

5m = 5m + 3 - 3

- Subtract the numbers

5m = 5m + 3 - 3

5m = 5m

4) Subtract 5m from both sides

5m = 5m

5m - 5m = 5m - 5m

5) Simplify

- Combine like terms

5m - 5m = 5m - 5m

0 = 5m - 5m

- Combine like terms

0 = 5m - 5m

0 = 0

This means it has infinite solutions.

But the commutative property addition have been shown.
