Sum of the angles are 180
125 + 41 + x = 180
166 + x = 180
x = 14
California for the 2017-’18 winter break, the University of Pennsylvania sophomore had been elected managing editor of a campus cooking publication called Penn Appétit. It’s a position he ended up never filling.
Quadratic function ( in standard form ):
y = a x² + b x + c
x = 0:
635 = 0 + 0 + c
c = 635
x = 1:
644 = a + b + 635
a + b = 9
x = 2:
719 = 4 a + 2 b + 635
4 a + 2 b = 84
and now we have a system:
a + b = 9 / * ( - 2 )
4 a + 2 b = 84
-------------------------
- 2 a + 2 b = - 18
+
4 a + 2 b = 84
-------------------------
2 a = 66
a = 33; b = - 24;
Function is:
f ( x ) = 33 x² - 24 x + 635
f ( 8 ) = 33 * 64 - 24 * 8 + 635 = 2,112 - 192 + 635 = 2,555
Answer: The number of waterfowl on week 8 would be 2,555.
Answer:
a) 0.5763 b)0.2119 c)0.2119
Step-by-step explanation:
In order to find find the probability that the battery lasts between 24 and 28 months, we have to find z
Z = (x – mean)/standard deviation
Le x be hours a battery last
P (24<x<28) = P((24– 26)/2.5 < z < (28– 26)/2.5)
P (24<x<28) = P(-0.8< z < 0.8)
Then we use the z table to find the area under the curve.
P (24<x<28) = 0.5763
the probability that the battery lasts longer than 28 hours
P (x>28) = P(z > (28– 26)/2.5)
P (x>28) = P(z > 0.8)
Then we use the z table to find the area under the curve.
P (x>28) = 0.2119
the probability that the battery lasts less than 24 hours
P (x<24) = P(z < (24– 26)/2.5)
P (x<24) = P(z < -0.8)
P (x<24) = 0.2119
5x + 2(x + 1) + 3 = 7x + 5
