Answer:
The probability that the cost for someone's dog is higher than for the cat is 33.2%.
Step-by-step explanation:
With the data given, we know that the difference in cost of medical care of dogs and cats have a normal distribution with μ=-20 and σ=46.
To know the probability of the cost for the dog is higher than the cat, we have to calculate the probability of P(d>0).
Then we have to calculate z, and look up in a standarized normal distribution table.
Calculate z:

The probability of the difference being higher than 0, we have:

We can say that the probability that the cost for someone's dog is higher than for the cat is 33.2%.
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
In geometry it is the shape made when a solid is cut through by a plane.
Example:
Part A: The name of the shape created by cross section of the prism is a square
<span>(We don't draw the rest of the object, just the</span><span> </span><span>shape</span><span> </span><span>made when you cut through.)</span>
<span>if Part B is a continuation from Part A then the shape of the resulting cross section would be a square.</span>
<span>if Part B is completely </span>separate<span> from Part A then the shape of the resulting cross section would be a rectangle.</span>
Since the wording is confusing I would, for part B, say that the shape of the resulting cross section is a rectangle regardless, because every square is always a rectangle but every rectangle is not always a square.
Part A- Square
Part B- Rectangle
Answer:
$1000
Step-by-step explanation:
It would be $1000 in total of all the people attending the party. This is because, you need to multiply, 50 and 20! The answer will be 1000.
Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
