The standard deviation of the scores is  6.48

For given set of scores,  88, 94, 80, 79, 74, and 83

Here, the number of observations = 6

The mean of the scores would be,

μ = Σx/n

μ = (88 + 94 + 80 + 79 + 74 + 83)/6

μ = 498/6

μ = 83

Using the formula of standard deviation,

σ = √((Xi−μ)^2)/n

σ = √[(88 - 83)² + (94 - 83)² + (80 - 83)² + (79 - 83)² + (74 - 83)² + (83 - 83)²]/6

σ = √(252/6)

σ = √42

σ = 6.48

Therefore,  the standard deviation = 6.48

Answer: A

Step-by-step explanation:

We see that the x is a right angle, so it must be a 90-degree angle!

For y, we know that a triangle has 180 degrees, we already know the other two angles are 90 and 64, add both together, equal 154.

180 - 154 = 26, so y is 26 degrees!

So the answer is A

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , a monomial that will make the expression as a square of a sum or a difference of trinomial is calculated as

(a-b)² = a² -2ab + b²

where a² = 36

taking square roots on both sides of the equation , we get

a = 6

-2ab = -12x

So , one of the variable is x

So , substituting the value of b = x , we get

( 6 - x )² = 36 - 12x + x²

Therefore , the value of the monomial is x²

Hence , The monomial that will make the expression as a square of a sum or a difference of trinomial is x²

Let the no of weeks after which both of them will have equal amount be x

therefore, after x weeks the amount of money in

Jaylen's account = 340 + 15x

Ryan's account = 220+ 25x

Now, since these amount is equal

therefore,

340 + 15x = 220+ 25x

on solving this equation we get ,

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable).

Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

We will see that the amount of gasoline increased by 5.25 gallons over that five-day period.

Here we want to study the table to see the total change in the amount of gasoline over the five-day period.

Now we need to study the given graph:

Notice that each day we have the change of that particular day, then we just need to add all of these changes and we will get the total change.

Where the negative numbers mean that the gasoline was used, and the positive numbers represent a charge in the gasoline (so it increases).

C = -1.05 - 1.20 - 0.85 + 10.50 - 2.15 = 5.25

The probabilities for the given problem is calculated as 0.081 and 0.06 respectively.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

Given that,

There are 3 blue marbles, 5 red marbles and 4 green marbles.

Then, the total number of marbles is 12.

The given problem can be solved as follows,

Part A:

The probability of getting 1 blue and 2 green marbles is,

P( 1 blue and 2 green) = (³C₁ × ⁴C₂)/¹²C₃

                                     = ( 3 × 6)/ 220

                                     = 9/110

                                     = 0.081

Part B:

The probability of selecting one blue marble = 3/12 = 1/4

After one blue marble is selected, the remaining number of marbles is 11.

Thus, probability of selecting 3 red marbles is,

⁵C₃/¹¹C₃

= 10/165

= 0.06

Part C:

In the Part A the probability is calculated by taking the ratio of total number of ways of selecting 3 marbles and the number of ways of selecting 1 blue and 2 green marbles.

And, in Part B the number of ways is calculated from the remaining number of marbles after one blue marble is chosen.

Hence, the probabilities for the given parts in the question are 0.081 and 0.06 respectively.

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

Since we know that Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Therefore, Under a counterclockwise

a point (x, y ) → (- x, - y ) , thus
