A population has parameters

Mathematics
1 answer:
Ket [755]2 years ago
8 0

Based on the population mean, the mean of the distribution sample means would be 204.6. The standard deviation would be 0.22.

<h3>What are the mean and standard deviation of the distribution?</h3>

The mean of the distribution sample means is the same as the population means which is 204.6.

The standard deviation can be found as:

σₓ = σ / √n

= 3.1 / √197

= 0.22

Three corners of a city bloc is located at (2,2) (2,-4) (-5,-4) on a coordinate plane what are the coordinates of the fourth cor
AleksandrR [38]

Answer:

(-5, 2)

Step-by-step explanation:

Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?

Solution:

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.

Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).

Hence the fourth coordinate is (-5, 2)

PLEASE HELP ASAP 40 PTS !!!!
snow_tiger [21]

Answer:

a  If we make the parent function 2sqrt(x)  then we translate to the left 4 units and up 5 units

Step-by-step explanation:

y = sqrt(4x+16) +5

y = sqrt(4 (x+4)) +5

y  = sqrt(4) sqrt(x+4) +5

y =2sqrt(x+4) +5

f(x) = sqrt(x)   this is the parent function

g(x) = sqrt(x+4)   This moves it to the left 4 units

h(x) = 2 sqrt (x+4)    This stretches it by 2 in the y direction

j(x) = 2 sqrt(x+4) +5  This moves it up by 5 units

y = 2sqrt(x+4) +5

This is to the left 4 units, stretched 2 units in the y direction and up 5 units

If we make the parent function 2sqrt(x)  then we translate to the left 4 units and up 5 units
