Answer:
The shape of the graph of the parametric equations given is:
Step-by-step explanation:
By inserting each of the equations given in a graphing calculator (Annex 1), it can be identified that both the first and second equations have an elliptical or ellipse shape, which is characterized by being periodic in the two directions in which it runs. Thus, the equation x = 3 cos t runs with elliptical motion on the Y-axis of the Cartesian plane, while the equation y = 2 without t + 1 runs with elliptical motion on the X-axis.
Answer:
0.9562
Step-by-step explanation:
Binomial probability is mathematically expressed as:
Given that p=0.18, n=5 , is calculated as:
Hence, the probability of no more than 2 successes in 5 trials is 0.9562
Step-by-step explanation:
Look for keywords
when you see "per" that means theres a rate (something happens every unit of time)
To write a rate you divide whatever happens by whatever unit of time youre useing
In this example our rate is 15$ <em>per</em> hour which can be written as:
15$/1 hour (but we usually dont write it if theres a 1)
You can think of this as a regular fraction
Here the hour will cancel and youre left with $
Answer:
A) Range
Step-by-step explanation:
The original mean would be 4.889. But when you add another 10 to the set, the mean becomes 5.400.
The original mode would be 1, because there are two 1's and only one of every other number. But when adding another 10 the the original set, you end up with two 10's so now the mode is 1 and 10.
The median changes from 5 to 5.5
So the answer has to be range.
Answer: 105 degrees
Step-by-step explanation:
so, since it is a parallelogram, adjacent angles are equal. so, we know that angle S and angle U are equal. that means we can subtract 150 from the 360 degrees of the full parallelogram. so, that leaves 210 degrees to work with. since it is shared amongst the other two equal angles, we just divide it by 2. so, that's how we get the answer.
