How do I write Domain and Range in inequality notation?

Mathematics
1 answer:
ArbitrLikvidat [17]3 years ago
8 0

Answer:

Domain: (-infinity, infinity)    Range:  (-infinity, infinity)

Step-by-step explanation:

They are parabolas, therefore you can assume that they go on infinitely. To find range, you must look at your y values. Look for your lowest point. Because the line goes done forever, your beginning mark would be (-infinity.

To find the other part, you look at your positive y values. Look for the highest value. Because this goes on infinitely, the completed version of your notation would be (-infinity, infinity). Be sure to use the infinity symbol though, which looks like an 8 rotated 90 degrees.


To find domain, look at your x values. To begin, look at your left-most values, which would be the negative numbers. Because the line goes on forever to the left, your notation would be (-infinity. To find the other part of domain, look at your positive x values. Because this line goes on infinitely as well, the completed version of your notation would be (-infinity, infinity). Infinity is never bracketed, it is always in parenthesis.

Bartholemew will draw with replacement 160 tickets at random from a box with five tickets [0, 0, 0, 1, 2]. Estimate the chance t
cupoosta [38]

Answer:

0.0786

Step-by-step explanation:

It is given that Bartholemew had drawn the replacement of 160 tickets.

There are five tickets = [0, 0, 0, 1, 2]

Now we need to find the estimate of the ticket that has 1 on it and it turns up on the 32 draws exactly.

Since the probability of the drawing 1 out of 5 tickets is given by,   $\frac{1}{5} = 0.2$

So the binomial with the parameter of n = 160 and p = 0.2, we get

P (it turns up on exactly 32 draws) = P(X = 32)

Therefore,

$C(160, 32)\times (0.2)^{32}\times (0.8)^{160-32}$

= 0.0786

Sonya paid $2.75 per pound for fresh fish last week. This week, she paid a total of $1.20 more when she purchased 3 pounds of fi
telo118 [61]

The price of fish this week is $3.15 per pound

Step-by-step explanation:

We have to find the total price of 3 pound fish for last week

So,

Price of fish per pound = $2.75

Price of 3 pound fish = 2.75 * 3 = $8.25

As she made $1.20 more in total for 3 pound fish this week

Price of 3 pound fish this week = 8.25+1.20 = $9.45

$9.45 is the total price for 3 pound fish this week.

So,

Price per pound this week will be:

=\frac{9.45}{3}\\=3.15

Hence,

The price of fish this week is $3.15 per pound
