Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that X will be smaller than 80.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The probability that X will be smaller than 80 is the p-value of Z when X = 80, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{80 - 100}{10}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a p-value of 0.0228.

0.0228 = 2.28% probability that X will be smaller than 80.

Answer:

1.5 as decimal, 1 1/2 as a fraction

Step-by-step explanation:

1. convert 2 5/6 & (-1 4/12) to a improper fraction.

17/6 and  -16/12

2. multiply 17/6 by 2 to match -16/12's denominator

17/6 * 2 = 34/12

We now have

34/12 + -16/12

A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.

We have:

[tex]\frac{34}{12}-\frac{16}{12}[/tex]

Now solve. 34-16 = 18

our answer is 18/12

The value for the given right triangle of [tex]x[/tex] is [tex]\pm \sqrt{2}[/tex].

By Pythagorean theorem and some algebraic handling, we have the following second order polynomial:

[tex](x-1)^{2}+(x+1)^{2} = 2.5^{2}[/tex] (1)

Where [tex]x[/tex] is the desired variable.

[tex](x^{2}-2\cdot x +1)+(x^{2}+2\cdot x +1) = 2.5^{2}[/tex]

[tex]2\cdot x^{2}+2 = 2.5^{2}[/tex]

[tex]2\cdot x^{2}-4.25= 0[/tex]

[tex]x = \pm \sqrt{2}[/tex]

The value for the given right triangle of [tex]x[/tex] is [tex]\pm \sqrt{2}[/tex]. [tex]\blacksquare[/tex]

Answer:

[tex]\frac{1}{2} x - 4[/tex]

Step-by-step explanation:

Perpendicular lines will have slopes that are the multiplicative additive inverse of each other: a line with slope 3/4 is perpendicular to a line with slope -4/3, for example.  You need a line that is perpendicular to a line with slope -2 (reading that from the -2 in the -2x portion of the given equation, which is written in slope-intercept form), so your new line must have slope +1/2.

With the slope and a point, we can come up with an equation using this formula:

y - y-coordinate = slope (x - x-coordinate)

So we have y - (-2) = 1/2 (x - 4).

Simplify the equation:  y + 2 = 1/2 x - 2

Subtract 2 from both sides: y + 2 - 2 = 1/2 x - 2 - 2

Simplify: y = 1/2 x - 4.

Answer:

Area of the shaded region is 104.96 m².

Step-by-step explanation:

Firstly, finding the area of circle with radius 8 cm by substituting the values in the formula :

[tex]{:\implies{\tt{A_{(Circle)} = \pi {r}^{2}}}}[/tex]

[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(8)}^{2}}}}[/tex]

[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(8 \times 8)}}}}[/tex]

[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(64)}}}}[/tex]

[tex]{:\implies{\tt{A_{(Circle)} = 3.14 \times 64}}}[/tex][tex]{:\implies{\tt{A_{(Circle)} = 200.96 \: {m}^{2} }}}[/tex]

Hence, the area of circle is 200.96 m².

[tex]\begin{gathered}\end{gathered}[/tex]

Secondly, finding the area of rectangle with length and breadth by substituting the values in the formula :

[tex]{:\implies{\tt{A_{(Rectangle)} = l \times b}}}[/tex]

[tex]{:\implies{\tt{A_{(Rectangle)} = 12 \times 8}}}[/tex]

[tex]{:\implies{\tt{A_{(Rectangle)} = 96 \: {m}^{2}}}}[/tex]

Hence, the area of rectangle is 96 m².

[tex]\begin{gathered}\end{gathered}[/tex]

Now, finding the area of shaded region by substituting the values in the formula :

[tex]{:\implies{\tt{A_{(Shaded)} = A_{(Circle)} - A_{(Rectangle)}}}}[/tex]

[tex]{:\implies{\tt{A_{(Shaded)} = 200.96 - 96}}}[/tex]

[tex]{:\implies{\tt{A_{(Shaded)} = 104.96 \: {m}^{2}}}}[/tex]

Hence, the area of shaded region is 104.96 m².

Answer:

D(-2,5)

Step-by-step explanation:

Point D has the same x coordinate as point C and has the same y coordinate as the point A

Hi!

We want to find the x and y value for point D.

We can see that point C is the same amount to the left as point D. That means they will have the same x-value.

Furthermore, we can see that point A is the same amount up as point D. That means that they will have the same y-value.

We will use the given coordinates, (x, y).

-------------------------------------------------------------------------------------------------------------

The x-value of point C is -2, and the y-value of point A is 5.

That means that the coordinates of point D are (-2, 5).

Step-by-step explanation:

Solution:

We know that the formula to write the equation of a circle is (x – h)² + (y – k)² = r², where:

First, let's find the radius of the circle. We know that the diameter of the circle is ten units. The radius is half of the diameter. This means that the radius is five units because it is half the diameter, which is ten units.

Creating the equation:

Hence, the equation to form a circle with center (-6, 2) and diameter 10 is (x + 6)² + (y – 2)² = 5².
