Answer:
C (4,7,10)
Step-by-step explanation:
For a set of numbers to represent the lengths of sides of triangle:
Sum of any two numbers must always be greater than than the third side.
out of the give options only C (4,7,10) follows the above condition.
Given:
Ten People
5 people = 30 years old
3 people = 32 years old
1 person = 31 years old
1 person = 65 years old
We need to arrange the ages in order from least to greatest.
30, 30, 30, 30, 30, 31, 32, 32, 32, 65
65 is the outlier.
A.) mean age without the outlier. count of the numbers : 9
5 x 30 = 150
1 x 31 = 31
3 x 32 =<u> 96</u>
total age 277
÷ # of pax<u> 9</u>
mean 30.77 round to the nearest tenth 30.80
b.) Standard deviation:
We need to calculate variance first:
5 pax : 30 - 30.80 = - 0.80 ⇒ -0.80² = 0.64 * 5pax = 3.20
1 pax : 31 - 30.80 = 0.20 ⇒ 0.20² = 0.04 * 1pax = 0.04
3 pax : 32 - 30.80 = 1.20 ⇒ 1.20² = 1.44 * 3 pax = 4.32
Variance : (3.20 + 0.04 + 4.32) / 9 pax = 7.56 / 9 = 0.84
Standard deviation is simply the square root of the variance.
Standard deviation = √0.84 = 0.916
0.916 round to nearest hundredths is 0.92
0.916 round to nearest tenths is 0.90
Answer:
6 / 2/3 = 9
Step-by-step explanation:
Carrie want to find out the number of towels that will fit each row along the back of the shower
The back of the shower measures 6 ft long
Each towel is 2/3 foot long
Therefore the equation which shows how to determine the number of tile that will fit in each row is
Since 1 tile is 2/3 foot long then the number the number of tile in each row is
= 6 / 2/3
= 6 ×3/2
= 18/2
= 9
Answer:
45
Step-by-step explanation:
Because if you replace the r with 3, it would be 15(3).
15(3) is the same as 15 × 3.
15 × 3 = 45
