Answer:
Each friend would have 2 bananas left, including yourself. If you are asking for the total amount of bananas, I am not sure since the amount of friends is not specified.
Since the Mongolian Meteorite weighs 22 tons and we know that the US one weights 70% or (.7) of that weight we can multiply 22 by .7 to get the weight of the United States meteorite.
15.4 Tons
Answer:
<A = 116°
<B = 64°
<C = <D = 90°
Step-by-step explanation:
In an inscribed quadrilateral, The sum of opposite angles is equal to 180°
If <A and <B are and also <C and <D opposite angles then:
<A+<B = 180° and
<C+<D = 180°
If <C = <D, then
<C+<C = 180°
2<C = 180°
<C = 180°/2
<C = 90° and <D = 90°
If <A = 9x+17 and <B = 8x-24, then;
9x+17+8x-24 = 180
17x-7 = 180
17x = 187
x = 187/17
x = 11°
<A = 9(11)+17
<A = 99+17
<A = 116°
<B = 180°-116°
<B = 64°
This expression simplified is 3x-9. This is solved by combining like terms.
-x + 4x = 3x
-5 - 4 = -9
Answer:
C) The expected value is -$40, so the man should not buy the warranty.
Step-by-step explanation:
The total cost to the man is expected to be the total of the amount he pays for the warranty and any amounts he gets because he has the warranty ...
-$100 +600×0.10 +0×0.90 = -$40
The expected value of the warranty is -$40. Based on that alone, the man should decide not to buy it.
____
<em>Comment on warranties</em>
The expected value of a warranty to the buyer is <em>always negative</em>. That is how warranty companies make their money. Clearly, <em>expected value</em> is not the only criterion that should be considered.
