=it is meant to be (x+1)2
=2(x) + 2(1)
= 2x +2

Answer:
In December, Zalma will have $480.
Step-by-step explanation:
The time from March to October is 7 months. In those 7 months, she gains $280. So every month, her investment gains $40.
The time from March to December is 9 months. She will gain $360 during that time. We add her initial $120 with the $360, and Zalma will have $480.
It's not confirmed, but it's what I got. :D
Answer:
Step-by-step explanation:
the mean is given by:
In our case this is:
side note: the main difference between sample mean and population mean is in the 'context'. However, the method to calculate them is the same.
By context I mean: if this the items are taken from some larger category for example: the ages of a few 'students' from a 'class'. Here 'students' are the sample from a larger set that is 'class'. The mean of the 'few students' will be called sample mean. In contrast, if we take the mean of the ages of the whole class then this is called population mean. (population mean == mean of the whole set)
In our case we aren't told exactly where these numbers come from, is this the whole set or a sample from it, the lack of context allows us to assume that the mean can either be population mean or sample mean. So we can safely use any symbol 
or 
.
Answer:
Tina is first
Tony is first
Theo is first
Step-by-step explanation:
Events with greater probability are more likely.
Let's put the probabilities in decimal form.
P(Tina is first) = 0.05
P(Theo is first) = %85 = 0.85
P(Tony is first) = 1/10 = 0.1
0.05 < 0.1 < 0.85
The events are listed below from least to most likely.
Tina is first, Tony is first, Theo is first
hope it helps
The degenerate conic that is formed when a double cone is sliced at the ap-ex by a plane parallel to the base of the cone is a <u>Point</u>.
<h3>What degenerate conic is formed?</h3>
When a plane that is parallel to the base of a double cone is used to slice the ap-ex, the conic section formed is a circle.
Circles lead to a Point degenerate conic being formed because a single point will be formed on the double cone that separates the shape.
