What is an outlier in the data set 65, 32, 9, 76, 69?

1 answer:

6 0

Put the numbers in order
9,32,65,69,76
Q1 = (32 + 9) / 2 = 41/2 = 20.5
Q2 = 65
Q3 = (69 + 76) / 2 = 145/2 = 72.5

now we find the IQR which is Q3 - Q1.....= 72.5 - 20.5 = 52
now we multiply 52 by 1.5....52 * 1.5 = 78

so the outliers will be :
Q1 - 78 .....20.5 - 78 = -57.5...anything below this
Q3 + 78.....72.5 + 78 = 150.5...anything above this

there is no outliers in here

$\text{Find how much Zelda paid for the visit to the ER:}\\\\\text{We know that her insurance pay's 85\% of the emergency room cost,}\\\text{ so multiply 0.85 from 4089 and subtract}\\\\4089*0.85=3,475.65\\\\4089-3,475.65=613.35\\\\\text{She pays \$613.35 of the emergency room cost}\\\\\text{We're not done yet, we also know she pays a \$100 deductible,}\\\\\text{So add 100 to 613.35}\\\\613.35+100 = 713.35\\\\\boxed{\text{She pays \$713.35}}$

Umnica [9.8K]

Answer:

The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20

Step-by-step explanation:

Given as :

The total amount spend for soup = $ 20

The cost of Tomatoes = $ 2.50 per pound

The cost of Red peppers = $ 4 per pound

Let the quantity of tomatoes to be bought = T pound

The quantity of red peppers to be bought = R pound

So, According to question

$ 2.50 × T + $ 4 × R = $ 20

I.e The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20 . Answer
