Answer: \(m\angle DE F=90^{\circ}\)

Step-by-step explanation:

The slope of \(DE\) is \(\frac{7-3}{5-4}=4\).

The slope of \(EF\) is \(\frac{3-2}{4-8}=-\frac{1}{4}\).

Thus, \(DE \perp EF\), meaning \(m\angle DE F=90^{\circ}\).

Answer:

The right solution is:

(a) 0.8849

(b) 12.28%

(c) 4.9935

(d) 28004

Step-by-step explanation:

Given:

Mean,

= 4.5

Standard deviation,

= 0.3

(a)

P(x > 4.14)

As we know,

⇒ \(z = \frac{4.14-4.5}{0.3}\)

      \(=-1.20\)

then,

⇒ \(P(z>-1.20) = P(z<1.20)\)

                          \(=0.8849\)

(b)

P(4.8 < x < 5.04)

= \(P(\frac{4.8-4.5}{0.3} < \frac{x-\mu}{\sigma} < \frac{5.04-4.5}{0.3} )\)

= \(P(1<z<1.80)\)

= \(P(z<1.80)-P(z<1)\)

= \(0.9641 -0.8413\)

= \(0.1228\)

or,

= \(12.28\) (%)

(c)

P(x > x) = 0.05

z value will be,

= 1.645

⇒ \(1.645 = \frac{x - 4.5}{0.3}\)

         \(x = 4.9935\)

(d)

P(x < 5.01)

⇒ \(z = \frac{x- \mu}{\sigma}\)

      \(=\frac{5.01-4.5}{0.3}\)

      \(=1.7\)

P(z < 1.70) = 0.9554

⇒ \(n = \frac{27875}{0.9954}\)

       \(=28004\)

Correct option is D, The perimeter of the trapezoid J K L M is units 9 + StartRoot 2 EndRoot + StartRoot 5 EndRoot units (= 9 + √5 + √2 units. )

The length of a two-dimensional shape's boundary is its perimeter. It is frequently referred to as the sum of the lengths of the sides of the object. Such shape's perimeter is equal to the side lengths added together algebraically. We have formulas for the various geometric shapes.

The vertices of KLMN an isosceles trapezoid are (-7,4), (-4,4), (-2,3), (-8,3).

perimeter of trapezoid JKLM = sum of sides

Using distance formula \(\sqrt{(x2-x2)^2 + (y2 - y1)^2}\),

Distance between the sides of trapezoid is,

(-7,4), (-4,4) =

\(\sqrt{(-7 + 4)^2 + (4 - 4)^2}\\= \sqrt{9}\\= 3 units\)

(-4,4), (-2,3) =

\(\sqrt{(-2 + 4)^2 + (3 - 4)^2}\\= \sqrt{5} units\)

(-2,3), (-8,3) =  

\(\sqrt{(-8 + 2)^2 + (3-3)^2}\\= \sqrt{6}^2\\= 6 units\)

(-7,4), (-8,3)

\(\sqrt{(-8 +7)^2 + (3-4)^2}\\= \sqrt{-1^2 + -1^2}\\= \sqrt 2 $ units $\)

So, the sum of sides will be -

= 3 + √5 + 6 + √2

= 9 + √5 + √2 units.

Answer:

\(d = 33\)

Step-by-step explanation:

Distance Formula: \(d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Simply plug in the 2 coordinates into the distance formula to find distance d:

\(d = \sqrt{(13-13)^2+(-14-19)^2}\)

\(d = \sqrt{(0)^2+(-33)^2}\)

\(d = \sqrt{(-33)^2}\)

\(d = 33\)

Answer:

the distance between the two points is 33 units.

Step-by-step explanation:

because the two points have the same x value, we only need to consider the y values.

find the difference to solve for the distance.

\(19-(-14)\\19+14\\33\)

the answer is 33 units.

Question 4: \(\frac{8}{1}\)

Question 5: \(\frac{4}{5}\)

Question 6: \(\frac{2.5}{1}\)

Question 7: \(\frac{1}{1}\)

The way to solve these types of questions, also know as "slope" is solved in the format \(\frac{y-y}{x-x}\) (y minus y over x minus x) which also can be known as \(\frac{rise-rise}{run-run}\) (rise minus rise over rune minus run). To solve this you can choose any two sets of numbers (the top and the bottom of a chart is 1 set) and you use its numbers to find the slope. One important rule when solving for slope is to never write your answer in decimal form and rarely write your answer as a whole number always answer questions in fraction form!!!! Anyway, the y and the x are already given so no need to find those as well. Here's the solving of all questions:

for this question I choose the number sets:\(\frac{24}{3} and, \frac{32}{4} in. ..equation... written... as, \frac{24-32}{3-4}\)

so, now the easy part, 24-32=-8

Next we solve the bottom, 3-4=-1

so we end up with \(\frac{-8}{-1}\) and when we simplify it can be written as \(\frac{8}{1}\) or just 8 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).

Now, for the rest of the problems I wont explain the solving process.

\(\frac{60}{185} and\frac{100}{235} written...as,\frac{60-100}{185-235}\)

60-100=-40

185-235=-50

\(\frac{-40}{-50} simplify...to,\frac{4}{5}\)

\(\frac{12.5}{5} and\frac{25}{10} written...as,\frac{12.5-25}{5-10}\)

12.5-25=-12.5

5-10=-5

\(\frac{-12.5}{-5}simplify...to,\frac{2.5}{1}\) or 2.5 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).

\(\frac{4}{2} and\frac{5}{3} written...as,\frac{4-5}{2-3}\)

4-5=-1

2-3=-1

\(\frac{-1}{-1}simplify...to,\frac{1}{1}\) or 1 (I recommend to always write in fraction form because some teachers will remove points if its not in fraction form).

Step-by-step explanation:

the average pen is 149mm. the average pen is 14.9cm. 160mm is closest.

It would have to be the 160mm.

This is because store-bought pens average 130 and 140mm/ 13 – 14 cm. This is closely followed by pens in the 140 – 150mm range.

The amount in the account at the end of 1 year is $5400.

The amount in the account at the end of 2 year is $5832.

What do you mean by interest rate?

The real yearly cost of funds over the course of a loan is the annual rate that is charged for borrowing (or made by investing), expressed as a single percentage number.

According to data in the given question,

We have:

Deandre places $5000 in an account that pays 8% interest compounded each year.

And no withdrawals are made from the account.

Now, we need to determine the amount of 8% interest on the $5000,

\(=\frac{5000}{100}*8\\ =400\)

Then, the amount in the account at the end of 1 year =$5000+$400

=$5400.

Now, we need to determine the amount of 8% interest on the $5400,

\(=\frac{5400}{100}*8\\ =432\)

So, the amount in the account at the end of 2 year =$5400+$432

=$5832.

The value x in the secant line using the Intersecting theorem is 4.

Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.

From the figure:

First sectant line segment = ( x - 1 ) + 5

External line segment of the first secant line = 5

Second sectant line segment = ( x + 2 ) + 4

External line segment of the second secant line = 4

Using the Intersecting secants theorem:

5( ( x - 1 ) + 5 ) = 4( ( x + 2 ) + 4 )

Solve for x:

5( x - 1 + 5 ) = 4( x + 2 + 4 )

5( x + 4 ) = 4( x + 6 )

5x + 20 = 4x + 24

5x - 4x = 24 - 20

x = 4

Therefore, the value of x is 4.

Option C) 4 is the correct answer.
