sineoko [7]3 years ago
7 0

Answer:

Check the dot plot below

Step-by-step explanation:

1) Generally, a dot plot graph is made up based on a Spread Measure Graph (on Excel). A dot plot is a simple graph Used for discrete and continuous variables, whether for univariate or multivariate statistics.

In this question, we have a dot plot of six groups means, notice that group 3 and group 5 had the same measure. Some dot plots use axis between their dots, to connect their information.

2) Retrieving the data from this original questionnaire, we have this table (check it below)

3) Then from these data we can construct from a spread measure graph, a dot plot, just adjusting lines, and the dots.

A ladder is leaning against a building and makes a 28 degree angle with the ground. the top of the ladder reaches up the buildin
Digiron [165]

The length of the ladder is 75ft.

<h3>What is hypotenuse?</h3>

The longest side, or hypotenuse, of a right-angled triangle is the side that faces away from the right angle. The Pythagorean theorem asserts that the hypotenuse's square length equals the sum of the squares of the lengths of the other two sides, and this can be used to determine the hypotenuse's length.

<h3>According to the information:</h3>

The ladder makes an angle of 28° with the ground and the top of the ladder reaches 35ft

Therefore, we have:

Sineα = opposite/hypotenuse

Where:

Opposite = 35

Hypotenuse = Length

α = 28°

substitute values and solve for the length, as following:

Sine(28) = 35/Length

Length = 35/Sine(28)

Length = 75ft

Therefore,

The length of the ladder is 75 ft.

A town has a population of 32,000 in the year 2002; 38,400 in the year 2003; 46,080 in the year 2004; and 55,296 in the year 200

The point is to find the growth rate. The compound formula is:

P=A(1+ growth rate)ⁿ, where A is the initial Value & P the new value after n years:
P₂₀₀₃ =P₂₀₀₂ (1+ growth rate)¹ (the period "n" from 2002 to 2003 being 1 year)

38400 = 32000(1+growth rate)¹
38400 / 32000 - 1= growth rate & growth rate = 1/5 = 0.2
You will balso find the same growth rate for:
P₂₀₀₄ = P₂₀₀₃(1+ growth rate)¹
P₂₀₀₅ = P₂₀₀₄((1+ growth rate)¹
between 2015 & 2002 THERE ARE 14 YEARS:

P₂₀₁₅ = P₂₀₀₂(1+0.2)¹⁴ & P₂₀₁₅ = 32000(1+02)¹⁴ = 410,854

Answer:

100

32x + 4 = 33x + 1. ( corresponding angles)

32x - 33x = 1 - 4

- x = -3

x=. 3

hence angle = 32*3 + 4 =. 100

hope it helps
