<t =33 since triangle RUT is isosceles (RU = TU)
<r + <u + <t = 180 triangle = 180
33 + <u + 33 = 180
66 + <u = 180
< u =114
<rus = < sut from the diagram
<rus + <sut = <u
x + x = 114
2x = 114
divide by 2
x = 57
<span>A: The middle 95% contain between 23.8 and 24.2 oz.(2 SDs under and over the mean)
B: Approximately 68% of boxes have between 23.9 and 24.1 oz of cereal (1 SD under and over the mean)
C: 2.5% of boxes contain more than 24.2, because 95% are within 2 SDs, and that includes lower and higher extremes.
D: 16% of boxes have more than 24.1, because 68% are within 1 SD of the mean, so 32 are left, and that includes lower and higher extremes.</span>
Answer:
the second one
Step-by-step explanation:
y is postitive when x < -1 and x > 3, but y is decreasing only when x < 1 so the case where both are true is when x < -1 option 2
Answer:
D
Step-by-step explanation:
f(x)=-3x-1
It is not always rational since zero is a rational number. If we have a rational number on the numerator and a 0 on the denominator then the quotient is not rational therefore the quotient of any two rational numbers is not always rational.
