Answer:

1)107

2)43

Step-by-step explanation:

Triangles interior angles add up to 180 degrees. In the first one, the first two angles are 31and 42, and if interior angles add up to 180, the equation should be 31+42+x=180 x=107.

Second one is hardes. A square means a right angle, or 90 degrees. 180-90 is 90. Next, we have the two angles x, and x+4 We know that triangles interior angles add up to 180 degrees, so x+x+4+90=180 2x+94=180 2x=86 x=43

Hope this helps :D Please mark brainliest if correct :D

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is t
aksik [14]

The absolute value inequality is given as |(p - 0.43)I ≤ 0.019

<h3 />

<h3>How to describe the proportion using the absolute value inequality</h3>

The proportion p = 43% = 0.43

Margin of error = 1.9% = 0.019

The value of the proportion can then be said to lie between

(0.43 - 0.019) ≤ p ≤ (0.43 + 0.019)

In order to convert to the absolute inequality we would be having

-0.019 ≤ (p - 0.43) ≤ 0.019

I (p - 0.43)I ≤ 0.019

Please help. Which graph represents a function? I think a.
drek231 [11]

graph B ( the lower one )

for a function to be defined there can only be one value of y for each value of x

graph A has more than 1 value of y for given values of x

for example ( - 1, 4 ) and  ( - 1, - 4 ) thus is not a function

graph B only has 1 value of y for a given value of x thus is a function
