Answer:

C. 1/49

Step-by-step explanation:

When there is a negative sign located inside the power, you must eliminate it. To do so, put the whole expression under 1, and then simplify from there:

7^-2 = 1/(7^2)

Simplify: 7^2 = 7 x 7 = 49

1/49 is your answer.

Exhibit a population of ten integers having mean=20 and variance=4
Alla [95]

exhibit population for ten integers is 15,19,19,20,20,20,21,22,22,22 mean is 20 variance is 4

Step-by-step explanation:

  • Mean is helps in finding the mid point of the data.
  • Variance is the variability of data it was here.
  • In order to get the data straight the combination of 4 was required.
  • 4 is variance one data set was 19 other had to be 22.
  • As mean is 20 three means had to be 20.
  • from mean 20 4 is greater then 20 and 3 is less then 20.
  • 15 being the lowest it compensated the variance to 4.
  • Mathematically there are many ways to do this using function.
  • This is to be found out at a traditional method.
  • Reducing or increase the number as it was integers.

The circumference of a circle is 23π m. What is the area, in the square meters? Express you answer in terms of pi
seraphim [82]

Answer:

<h2>132.25π  m²</h2>

Step-by-step explanation:

The circumference of a circle is 23π

On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.

then

by equating the last two expressions we get: 23π = 2πr then r = 23/2

then

the area = π × r² = (23/2)²×π = (132.25)×π
