Answer:
b. 255.5 to 499.5
Step-by-step explanation:
The middle 50% is the range between the first and third quartiles. In this group of 9 numbers, the first quartile is the average of numbers 2 and 3 when the numbers are listed from smallest to largest.
first quartile = (230 +281)/2 = 255.5 . . . . . . matches answer choice B
The third quartile is the average of numbers 7 and 8:
third quartile = (468 +531)/2 = 499.5 . . . . . also matches answer choice B
The middle 50% is 255.5 to 499.5.
_____
When I put the numbers in order, I get ...
198 230 ^ 281 246 376 426 468 ^ 531 540
^ indicates that the quartile here is the average of the adjacent numbers
bold indicates the median (2nd quartile)
What is the probablity for the number of times Jada will pull a tile wit a star?
Answer: Number of tiles pulled out of the bag by Jada = 10, so she completed 10 trials.
The outcome of each trial was star, circle or a square.
Step-by-step explanation: We can find the experimental probability of pulling each shape from the bag based on the outcomes of Jada's experiment and number of trial.
- P(Star) = Number of stars/Number of trials= 5/10
- P(Circles)= Number of circles/Number of trials =3/10
- P(Square) = Number of Square/Number of trials = 2/10
Here, P refers to Probability of an outcome
If Jada repeats the experiment, She would likely again pull more stars than circles or square. She may get different number of stars,circles or squares but over a large number of trials, she would expect the ratio of the stars in the proportion. We can use this proportonal relationship to get the reasonable prediction about te number of times she pull different shape tiles.
<u>Number of outcomes(10 trials) </u> = <u>Number of outcomes(100 trials)</u>
Number of trials(10 trials) Number of trials (100 trials)
- Numbeof stars = 5/10 =s/100
5*10/ 10*10 =50/100 - Number of Circle = 3/10 = c/100
3*10/10*10 = 30/100 - Number of square = 2/10 = q/100
2*10/10*10 = 20/100
If she does the experiment 100 times then she should expect to pull out 50 stars tile, 30 circles and 20 Square.
Hence, Jada pulled out the 100 tiles from the bag.

Answer:
if someon is building a train then how are they gonna fit a whole full-sized train on their blueprints. they would have to make a scale model to fit on the paper
Step-by-step explanation:
Answer
Perimeter = 1.75 times larger
Area = 3.0625 times larger
Step-by-step explanation:
Let the original quadrilateral have sides of a, b, c, d
Perimeter of the New Photograph
- Then the perimeter of the original is P = (a + b + c + d)
- Now the perimeter of the new quad is P = 1.75a + 1.75b + 1.75c + 1.75d
- Using the distributive Property we get P = 1.75(a + b + c + d) So the new perimeter is 1.75*the old perimeter.
Area of the New Photograph
The area is a little harder. Suppose the Old figure had an Area found by the formula of
- Area = e * f Each measurement is increased by a factor of 1.75
- Area_new = 1.75e * 1.75f
- Area_new = 3.0625 * e * f
- Area_new = 3.0625 * old area
