Outliers 30 no outliers
A, Reading has a suspected outlier in the 30-hour value.
Answer:
The correct option is: A,B
Step-by-step explanation:
" An outlier is a odd value which on removing from the data leads to the less mean as calculated mean on including that value ".
There are total 10 data points.
- The table for reading is given as:
3 3 4 5 6 7 10 12 14 30
The mean of this data is given by:
Also the mean after omitting the odd value i.e. 30 we get:
Hence, there is a change in its mean;
Hence the outlier for reading is 30.
- The table for Video is given by:
1 2 3 4 6 7 8 8 9 15
The possible maximum value here is 15 so we will check whether it is an outlier or not.
The mean of this data is given by:
Also the mean after omitting the odd value i.e. 15 we get:
Hence, there is a change in its mean hence 15 is an outlier.
Hence option A and B are true.

Answer (4):
4√7 feet
pythagroen theorem
for a right triangl of legs legnth a and b and hypotnuse c
a^2+b^2=c^2
legs are 3 and height
hypotnuse=legnth of lader=10
h^2+3^2=1^2
h^2+9=100
minus 9 both sides
h^2=91
sqr both sides
h=9.539
h=9.54 ft

Answer:
a=6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10^2
a^2 + 64= 100
a^2 +64-64 = 100-64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6
Answer:
a = 6
- The length of side a is 6.
Step-by-step explanation:
According to the question,
Using Pythagorean theorem
( a )² + ( b )² = ( c )²
- Where, a and b are the base and c is the length of hypotenuse.
( a )² + ( 8 )² = ( 10 )²
evaluate the exponent
a ² + 64 = 100
subtract 64 from each side
a ² + 64 - 64 = 100 - 64
a ² = 36
Take the square root of each side
√a² = √36
a = 6

119th odd number is: (2*119) - 1 = 237
69th even natural number subtracted from the 119th odd natural number is:
237 - 138 = 99.
Answer:
99
Step-by-step explanation:
The answer is 99 since you need to double 69 and also 119 and then subtract 1 from the double of 119. Then you would subtract them to get 99.
