Answer 1
Answer: x = 2



First, combine like values. 8x - 3x = 5x

Now, you are left with 5x = 10

Next, divide both sides of the equation by 5.

5x / 5 = 10 / 5

x = 2

There’s the answer!

Answer:

104.1

Step-by-step explanation:

Use SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

In this case, the hypotenuse is x, and the side opposite of the 22° angle is 39.  Since we have opposite and hypotenuse, we need to use sine.

sin 22° = 39 / x

x sin 22° = 39

x = 39 / sin 22°

x ≈ 104.1

The median of the data set is 81 what number is missing in data set 82, 87, 77, 70, 80, 88

Answers

The missing dataset is 81 at the 4th position.

We have the following data set -

82, 87, 77, 70, 80, 88

whose Median is -  81

We have to find out the missing data in this dataset.

What is the formula to find the Median of a set of odd number of elements (say N) ?

If a set consist of odd number of elements, then the median of that set of numbers is the is the element at the position ((N+1)/(2)) ^(th).

Let the missing element be x. Now, the data set becomes -

82, 87, 77, 70, 80, 88, x

To total number of elements in the dataset = 7, which is a odd number.

The element at the ((N+1)/(2)) ^(th) position for odd number of elements equals to Median which is equal to 81.

Hence, the missing dataset is 81 at the position -    ((7+1)/(2)) ^(th) = (8)/(2) = 4th position.

A magician showed a magic trick where he picked one card from a standard deck. Determine what the probablity is that the catd will be a black queen card?

Answers

In a standard deck of cards there are 52 cards. 13 cards per suit and 4 suits. There are 4 queens in a deck. A queen of hearts (red,) a queen of diamonds (red,) a queen of clubs (black,) and a queen of spades (black.) That means that there are two black queens in a deck of 52 cards. Therefore the probability is 2 out of 52 or 2/52. This also simplifies to 1 out of 26 or 1/26.
standard deck: 54 card
there is only 1 type of each card
2 types of each color card
4 types of each number or sign card
there are 2 black types in a card deck spades-clubs
so 2/54 or 1/26 

Give the equation for a circle with the given center and radius.
Center at (4, 1), radius = 6

Answers

The equation of circle can be given as :

(x-h)² +(y-k)²=r²

where (h,k) is center of circle and r is radius

the center is at (4,1) and radius =6

so equation becomes,

(x-4)² +(y-1)²=6²

(x-4)² +(y-1)²=36 is the equation of circle
