A.The sum of two products; there are two terms
There are 2 red marbles and 3 blue marbles, with a total of 5 marbles in the bag.
When Jonathan chooses a marble, we are saying that he is choosing the marble randomly.
Let's make a fraction. We want to know the chance of picking one of the 2 red marbles among all 5 marbles.
Divide 2 by 5
2/5
That's already a simplified fraction. If you want to convert this into decimal and into percentage, you would get
2/5
= 0.4
= 40%
Those are all acceptable answers.
Have an awesome day! :)
The formula for interval estimate would be: μ = M ± Z(<span>sM</span>)
Where: μ is estimate
M is the mean
Z is the z value
(<span>sM</span>) is the standard
error
μ = M ± Z(<span>sM</span>)
n = 200 rather than 50 (√200 = 2√50)
<span>⇒ ME = (1/2) * 1.32 = .66</span>
<span>Using the formula above, plugging this in will give us: μ
= 19.76 ± .66</span>
<span> = 19.76 ± .66 is
the confidence interval or interval estimate</span>
The following statement describes a rebate -
A.) The Shopper receives a discount now and pays sales tax on the discounted price of the item.
Explanation:
This option is correct because a rebate is described as a discount and one gets its benefit when one pays the tax on the discounted item. The discount is given at the same moment and the tax is paid on the same price.
Answer with explanation:
When point (x,y) in two dimensional plane is converted to polar plane,that is in terms of (r,α)
1. Origin (0,0)→Pole
2. x=0,y=0 becomes can be written as→ equation of polar axis,which is equal to 0.
the two curves drawn here has following line of symmetry
1. Symmetry along four lines of blade shaped curve,one along polar axis that is x=0,y=0 and two along,x=y and y=-x.
2. The curve which is in the shape of Cardioid has 1 line of symmetry that is , x=0.
The features which are present in the polar graph
Option:
A. Symmetry about the line
B. Symmetry about the polar axis = 0
