Answer:

C) 53.3%

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = 0.5328 = 53.3%

Step-by-step explanation:

Explanation

Given that Mean of the Normal distribution(μ)  = 222

Given that the standard deviation of the Normal distribution (σ) = 16

Let 'X' be the random variable in the Normal distribution

we have to find that the probability that a data value is between 206 and 230

solution:-

Step(i):-

Let  'X' = 206

[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{206-222}{16} = -1[/tex]

Let X = 230

[tex]Z = \frac{x-mean }{S.D} = \frac{230-222}{16} = 0.5[/tex]

Step(ii):-

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = P( -1≤Z≤0.5)

                          = |A(0.5)+A(-1)|

                         = 0.1915+0.3413

                         = 0.5328

final answer:-

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = 0.5328 = 53.3%

Step-by-step explanation:

Given GP with:

We can find the common ratio:

Using the nth term formula we can work out the first term:

So the explicit rule is:

3/1 so 3

9 \3 = 3

4/4= 1

the denominator is 1 because they are both the same whole number.

Step-by-step explanation: amazon they have everything

Answer:

No.

Step-by-step explanation:

2(x-3) + 1  = 2x - 6 + 1 = 2x - 5

2x + 6   ≠   2x -5, so no, they aren't equivalent.

The expression 2(x - 3) + 1 and 2x + 6 are not Equivalent.

Equivalent expressions are expressions that perform the same function notwithstanding their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).

We have two expressions to compare 2(x- 3) + 1 and 2x +6 .

Now, simplifying the first expression as

= 2(x -3) + 1

= 2x - 6 +1

= 2x - 5

and, the second expression is 2x + 6.

Thus, both of expression are not Equivalent.

Answer: centimeter

Step-by-step explanation:

The best unit of measurement for measuring the foot will be centimeter.

A unit of measurement is a standardized quantity of physical property, used as a factor to express the quantity of that property that exists. Among the first devices invented by humans were measuring units.

Given that, which will be the best unit of measurements for measuring the foot,

So, from the given options, the kilometer is very long for a human foot, millimeter is too small for a human foot and meter is also slightly longs,

We often measure the human body parts like hand, nose, tongue etc. in cm.

Hence, the best unit of measurement for measuring the foot will be centimeter.

Answer:

12

Step-by-step explanation:

Pythagoras Theorem is clearly used in this question.

To Calculate the Hypotenuse:

C = [tex]\sqrt{a^2+b^2}[/tex]

The Adjacent angle has already given as 9, so you can factor that into the question.

In Order to calculate the Opposite angle you need to use the following formula.

[tex]b = \sqrt{c^2-a^2}[/tex]

With the integers we already have for both Hypotenuse and Adjacent factored in this will be your equation:

[tex]b = \sqrt{15^2-9^2} = 12[/tex]

Therefore you answer is 12, Hope this helps, feel free to make as brainilest.

Answer:

The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles. The adjacent angles are the angles which have a common vertex.

The total value of the coins in the jar is A = $ 0.55

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 , the value of A is

Substituting the values in the equation , we get

The number of quarters = 1

So , the value of quarters = $ 0.25

The number of cents = 2

So , the value of cents = $ 0.20

The number of nickels = 2

So , the value of nickels = $ 10

And , the equation will be

A = value of quarters + value of cents + value of nickels

On simplifying , we get

A = 0.25 + 0.20 + 0.10

A = $ 0.55

Therefore , the value of the coins is A = $ 0.55

Hence , the equation is A = $ 0.55

Answer:

we know that isoceles has pair of angle with same measurement and sum of interior angle of triangle is 180°

Step-by-step explanation:

Let other angle be x

x+x+74°= 180°

=> 2x = 180°-74°

=>x = 106°/2

=> x= 53°

If one of the angles in an isosceles triangle is 74°. Then the other two angles will be 53°.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, two angles and their opposite sides are equal.

One of the angles in an isosceles triangle is 74°.

Let the other angle be x.

Then the value of x will be

x + x + 74° = 180°

            2x = 180° – 74°

            2x = 106°

              x = 53°
