The mean of the data is 18. What number is missing? 21,11,_,27,22,13,16

Ludmilka [50]

The missing number is 16

Solution:

Given that mean of data is 18

Let "x" be the missing number

The data set is:

21, 11, x , 27, 22, 13, 16

Sum of data set = 21 + 11 + x + 27 + 22 + 13 + 16

Sum of data set = 110 + x

The mean is given by formula:

$Mean = \frac{\text{sum of all numbers}}{\text{total numbers in data set}}$

Substituting the values we get,

$18 = \frac{110+x}{7}\\\\126 = 110 + x\\\\x = 126 - 110\\\\x = 16$

Thus the missing number is 16

a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance that it covers?

svp [43]

We know that

1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long

applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall

a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft

the answer is
5.92 ft
