These plots show the number of kilometers a group of students at Middleton Middle School and at Westwood Middle School travel to

vitfil [10]

Answer:

Middleton only

Step-by-step explanation:

Sometimes, in a data set, there is a number that is much larger or much smaller than the others generally tend to be. These numbers that are far away from the average are known as outliers

The data set for the students at Middleton Middle School:

1 2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 9

We can note that most of data is between 1 and 6, the gap between them is 0 or 1, but there is one of the data which is 9, the gap between 9 and 6 is 3

So, 9 would be considered an outlier.

So, The shapes of plots shows an outlier is Middleton only

The data set for the students at Westwood Middle School:

2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 6 6

We can note that all of data is between 2 and 6, the gap between them is 0 or 1

So, There is no outlier for the set of data.

Jackie is a toll booth employee. One day, she wrote the expression:0.75m= 15.75She let m represent the number of motorcycles tha

Brrunno [24]

Answer:

Step-by-step explanation:

The expression Jackie came up with is:

0.75m = 15.75.

To get the value of m, we divide both sides by 0.75

0.75m = 15.75.

0.75m/0.75 = 15.75/0.75

m = 1575/75

= 21

For each exponential model indicate if the function represents growth or Decay, then identify initial value, growth/Decay factor

Dennis_Churaev [7]

Answer:

(g/d, initial, factor, rate)
(g, 45, 1.05, 5%)
(d, 50, 0.70, -30%)
(g, 90, 1.42, 42%)
(d, 120, 0.45, -55%)

Step-by-step explanation:

Exponential functions all have the form ...

f(x) = (initial value)(growth factor)^x

where (growth factor) is defined as ...

(growth factor) = (1 + growth rate) ⇒ growth rate = growth factor - 1

If the growth rate is negative (growth factor is less than 1), then it is decay, rather than growth. Growth rate is often expressed as a percentage. A growth rate of a negative amount may be reported as a decay rate of a positive amount. (Above, we have kept the decay rates negative to reinforce the fact that they are decay. Your grader may expect these values to be positive.)

_____

So, to fill in the table, compare the given functions to the form above. The results are listed in the answer section above.

The longest side of a right triangle is 15 feet. The third side is 15 less than three times the shortest side. Find the length o

luda_lava [24]

Answer: The shortest side is 9ft

Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).

If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).

Now we have three sides of a triangle which we can label as 15, x and 3x - 15

By applying the Pythagoras theorem, AC² = AB² + BC²

(Where AC is the hypotenuse and AB and BC are the other two sides)

15² = X² + (3x-15)²

By expansion, (3x-15)² becomes 9x² - 90x + 225

Hence, 225 = X² + 9X² - 90X + 225

225 = 10X² - 90X + 225

Subtract 225 from both sides of the equation

10X² - 90X = 0

Factorize the left hand side of the equation by 10x

10x (x - 9)= 0

Therefore, either

10x = 0 OR

x - 9 = 0

If 10x=0, then x=0. OR

If x - 9 = 0, then x = 9

The length of the shortest side is 9ft.
