Step-by-step explanation:
Leia is operating a digital spinner game in which a player spins an arrow and is given a prize based on where the spinner lands. Leia can program the probability of each of the outcomes. The stuffed teddy bear is the best prize, so she programs the spinner so that the probability of not getting a bear twice in a row is greater than 3 times the probability of getting the teddy bear in one spin.
Write an inequality that compares the probability of getting the teddy bear to the probability of not getting the teddy bear, using p to represent the probability of getting the teddy bear in one try.
In the problem, we are given that the probability of getting a bear is equal to p. Where probability is the share of successful outcome in this case is the bear) over total outcomes (total amount of prizes).
The likelihood of not receiving a bear two times in a row is containing of 2 tries:
try 1: 1st spin gets a bear, 2nd spin does not receive a bear
total probability of try 1 = p * (1 – p)
try 2: 1st spin does not get a bear, 2nd spin gets a bear
total probability of try 1 = (1 – p) * p
The total probability of the 2 tries is just the sum of the 2:
Overall probability of not getting a bear twice in a row= p * (1 – p) + (1 – p) * p
Simplifying this will give us:
Overall probability of not getting a bear twice in a row = 2p * (1 – p)
Therefore, the likelihood of not receiving a bear twice in a row > 3 times the probability of getting the teddy bear. Rewriting the statement, will give us the inequality of 2p * (1 – p) > 3 p
To compare the probability of getting the teddy bear to the probability of not getting the teddy bear, use the inequality p^2 + 3p - 1 < 0.
Explanation:To write an inequality that compares the probability of getting the teddy bear to the probability of not getting the teddy bear, we can use the inequality sign. Let's represent the probability of getting the teddy bear in one try as 'p'. Since we want the probability of not getting a bear twice in a row to be greater than 3 times the probability of getting the teddy bear in one spin, we can write the inequality as:
1 - p * p > 3p
Simplifying the inequality, we get:
1 - p^2 > 3p
Then, rearranging the terms, we get:
p^2 + 3p - 1 < 0
This is the inequality that compares the probability of getting the teddy bear to the probability of not getting the teddy bear.
Polygons QRST and Q’R’S’T’ are shown on the coordinate grid: A coordinate plane with two polygons is shown. Polygon QRST has vertices Q at 3 comma negative 5, R at 2 comma negative 1, S at 5 comma 0, and T at 5 comma negative 4. Polygon Q prime R prime S prime T prime has vertices at Q prime negative 5 comma negative 4, R prime at negative 1 comma negative 3, S prime at 0 comma negative 6, and T prime at negative 4 comma negative 6. What set of transformations is performed on QRST to form Q’R’S’T’? A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the right A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the left A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin A translation 1 unit to the right followed by a 270-degree counterclockwise rotation about the origin
The transformation performed on QRST to form Q'R'S'T' is a 180-degree clockwise rotation about the origin followed by a translation 1 unit to the left.
Explanation:The transformation of the polygon QRST to Q’R’S’T’ involves a series of steps. To determine these steps, we look at the movement of each vertex from the original polygon to the new. The coordinates of Q change from (3, -5) in QRST to (-5, -4) in Q'R'S'T'. This signifies a 180-degree clockwise rotation about the origin followed by a translation. Given the options, the answer is ‘A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the left.’
Let's walk through how this works: The rotation leaves us with points Q at (-3, 5), R at (-2, 1), S at (-5, 0) and T at (-5, 4). The translation of 1 unit to left then changes these coordinates to Q' at (-4, 5), R' at (-3, 1), S' at (-6, 0), and T' at (-6, 4), hence matching the given coordinates of Q'R'S'T'.

Sanjay needs to ride his bike for 3 weeks to cover a distance of

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Sanjay rides his bike to work 15 kilometers in two days.
∴ In one day he rides (15/2) = 7.5 kilometers.
So, to ride his bike for 150 kilometers he needs (150/7.5) = 20 days.
We know 1 week is 7 days.
∴ Sanjay needs (20/7) = 2.86 weeks, but weeks comes in integers and we'll choose 3 weeks as in 2 weeks he won't be able to cover a distance of 150 kilometers.

In a cafeteria, there are the same number of 3-legged stools as there are of 4-legged chairs. If stools have 120 fewer legs than chairs, how many people can sit in this cafeteria?
The cafeteria can seat 120 people.
Let's denote the number of 3-legged stools as S and the number of 4-legged chairs as C. According to the problem, there are the same number of stools and chairs, so we have:
S = C
Next, we are told that the stools have 120 fewer legs than the chairs. Since each stool has 3 legs and each chair has 4 legs, we can set up the following equation:
3S + 120 = 4C
Since S = C, we can substitute C for S in the equation:
3C + 120 = 4C
Now, let's solve for C:
120 = 4C - 3C
120 = C
Now that we know there are 120 chairs, and since the number of stools is the same as the number of chairs, there are also 120 stools. Each chair can seat one person, and each stool can also seat one person, so the total number of people that can be seated is the sum of the number of chairs and stools:
Total seating = C + S
Total seating = 120 + 120
Total seating = 240
However, since there are only 120 chairs and 120 stools, and we cannot have half a piece of furniture, the maximum number of people that can be seated is the number of chairs or stools, which is:
Total seating = 120
Therefore, the cafeteria can seat 120 people.

Write an expression to find the difference in the maximum area and minimum area of a nys high school soccer field. Then evaluate the expression.
Max length 100yards
Max length 120 yards
Minimum width 55 yards
Maximum width 80 yards
The difference between the maximum and minimum area of the soccer field is found by calculating the maximum and minimum area using the given dimensions, and then subtracting the minimum area from the maximum area. Result is 4100 square yards.
Explanation:First, the area of a rectangle (like a soccer field) can be found with the formula Area = Length x Width. To find the difference between the maximum area and the minimum area of the field, we'll need to do two calculations.
For the maximum area, we'll use the maximum length of 120 yards and the maximum width of 80 yards: Max Area = 120 yards x 80 yards = 9600 square yards.
For the minimum area, we'll use the minimum length of 100 yards and the minimum width of 55 yards: Min Area = 100 yards x 55 yards = 5500 square yards.
Now you subtract the minimum area from the maximum area: 9600 square yards - 5500 square yards = 4100 square yards. This is the difference in area between the smallest and largest possible soccer fields.

A magazine has 96 pages. there are advertisements on 75% of those pages. how many pages do not have advertisements?
There are 24 pages in the magazine that do not have advertisements.
To find the number of pages without advertisements in a 96-page magazine, we first calculate the number of pages with advertisements.
Calculate 75% of 96 (since 75% of the pages have advertisements).
[tex]\( 75\% \times 96 = 0.75 \times 96 = 72 \)[/tex] pages with advertisements.
Subtract the pages with advertisements from the total number of pages to find the pages without advertisements.
[tex]\( 96 - 72 = 24 \)[/tex] pages without advertisements.
So, there are 24 pages in the magazine that do not have advertisements.

x = 7
According to the question -
Assume that Wendy receives $x.
Then Jon will receive $(x - 2500).
