Step-by-step explanation:
NPL+MNP=180°(being the sum of co-interior angle)
y°+68°=180°
y°=180°-68°
y°=112° answer
I have no idea guy evens dhjrbtixndjebusnrjfkrbfjr she she s
Th z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
hence:
z=(240-200)/20
z=2
Whenever the questions asks for the probability and has "or" you have to add the two probabilities. In the same way, "and" implies multiplication. Therefore, the probability that someone swims is:
Probability that someone runs:
Thus, if you add them:
So, the probability that someone swims <em>or</em> runs is
1/2 or
50%.

Since both equations are equal to y, they must equal each other. So set them to equal each other.
28 + 0.05x = 25 + 0.07x (✿ ♥‿♥)
Let's start by subtracting 25 from both sides!
3 + 0.05x = 0.07x (28-25=3, 25-25=0)
Now let's subtract 0.05 from both sides Ｏ(≧▽≦)Ｏ
3 = 0.02x
We need this x by itself, so let's get rid of it. Do this by divide both sides by 0.02 （ ´_⊃｀）
150 = x
So x = 150. Let's test this. Substitute 150 in for x in both equations! ＼（＾○＾）人（＾○＾）／
28+0.05(150) = 25+0.07(150)
28 + 7.5 = 25 + 10.5 (0.05*150=7.5, 0.07*150 = 10.5)
35.5 = 35.5
It works! (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
So x = 150
