Angle 3: 24 degrees- the angle across from it is 24 which makes this one 24 so it’s congruent.
Angle 1 and 4: 78 degrees- on one side of these angles (the line the seperates it running parallel) the angles total to 180 degrees, we take angle 3 which was 24 and subtract that from 180. That equals 156 which we then divide into two because we have two angles left to solve for which makes 78 each.
Angle 2: 71 degrees- We know angle 3 is 24 and we have a written angle as 85. Knowing each side of these angles equals 180 degrees, we add 85 and 24 to get 109. We then will subtract 180 from 109 to get our missing angle which is 71 degrees.

I hope I could help :)

Jude estimates that his index finger is 3 inches long. He calculates the circumference of one of his bongo drums to be 27 inches

anzhelika [568]

Answer: 9 finger lengths

Step-by-step explanation: Since the circumference is the middle line passing through (usually a circle....) 27/3 equals 9, which basically means that 9 of Jude's index fingers can pass through the circumference of one of his bongo drums. Hope this helps, 15402256.

Given the function defined below, what is the value of the 4th term?

MakcuM [25]

Answer:

The 4 t h term is f(4) = 143

Step-by-step explanation:

Explanation:-

Given function f(1) = -4

Given 'nth' term is f(n) = -3f(n-1) +5

Put n =2 f(2) = -3 f(2-1) +5

= -3 f(1) +5

= -3 (-4) +5

= 12 +5

f(2) = 17

put n= 3

f(n) = -3f(n-1) +5

f(3) = -3 f(3-1) +5

= -3f(2) +5

= -3(17) +5

= -51+5

f(3) = -46

Put n=4

f(n) = -3f(n-1) +5

f(4) = -3f(4-1) +5

f(4) = -3f(3)+5

f(4) = -3(-46)+5

f(4) = 138 +5

f(4) = 143

Final answer:-

The 4 t h term is f(4) = 143

Which scatterplot has a correlation coefficient closest to r = 1?

qwelly [4]

Answer:

The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.

Step-by-step explanation:

The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope

Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.

The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images
