Answer:

x=80

Step-by-step explanation:

the figure depicts a pentagon.

we can use linear pair method to find x

we should find interior angles

angle E= 180-90= 90

angle D=180-60= 120

angle C=180-x

angle A= 90 given

angle B= 180-40= 140

angle sum of a pentagon = 540

by formula (n-2)180. n is the number of sides

equation= 90+120+180-x+90+140= 540

620-x= 540

620-540=x

80=x

P(-3,-5) and Q(1, -3) represent points in a coordinate<br> plane. Find the midpoint of PQ.
Karolina [17]

Step by step explanation :

The two points are ,

  • P( -3 , -5)
  • Q (1 , -3)

We can find the midpoint by finding the median of x coordinate and y coordinate .

\tt\to Midpoint = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint =\bigg(\dfrac{-3+1}{2},\dfrac{-5-3}{2}\bigg)\\\\\tt\to Midpoint = \bigg( \dfrac{-2}{2},\dfrac{-8}{2}\bigg) \\\\\sf\to\boxed{\orange{\tt Midpoint = (-1,-4)}}

Kim's softball team was playing in the championship game. When there were 444 innings left, the team was losing by a score of 17
olga nikolaevna [1]

The inequality to determine the number of runs per inning, p Kim's team could have scored is; 4r + 6 > 17

<h3>How to write an Inequality?</h3>

Let r represent the number of runs per inning. Thus for 4 innings, we have 4r.

The team already has 6 runs. Now add the additional runs to this to get;

4r + 6

The team wants to score more than the other team, this means they need more than 17 and so the inequality required is;

4r + 6 > 17

Subtract 6 from each side to get;

4r + 6 - 6 > 17 - 6

4r > 11

Divide both sides by 4 to get:

r > 2.75

Approximating to a whole number gives;

r > 3

Consider the following confidence interval interpretation: We are 98% confident that the true mean laptop screen size is between
GalinKa [24]

Answer:

Incorrect

Step-by-step explanation:

This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.

or 98% of the laptop have screen size between 19.2 and 21.4 inches

However, the interpretation would have been correct if it would have stated as - Value of the population mean i.e mean size of the laptop screen lies within the confidence interval.

A 40-foot ladder is leaning against a building and forms a 29.32° angle with the ground. how far away from the building is the b
zaharov [31]

The distance between the building and the ladder is 34.876 foot.

<h3>What is a Right Triangle?</h3>

A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.

The ladder forms a right triangle with the building and the ground,

The length of the triangle is 40 foot

The angle made by the ladder is 29.32 degree

By using Trigonometric Ratios

cos 29.32 = Base /  Hypotenuse

cos 29.32 = Base / 40

0.8718 × 40 = Base

Base = 34.876 foot

Base is the distance between the building and the ladder.

Base of the ladder = 34.876 foot
