Answer:

(-1,1)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

(-5+3)/2 = -2/2 = -1

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

(3+-1)/2 = 2/2 = 1

(-1,1)

Answer:

(-1,1)

Step-by-step explanation:

The midpoint of a line can be found using the following formula:

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Basically, to find the midpoint, add the x-coordinates and divide by 2, then add the y coordinates and divide by 2.

X-coordinate

Add the x-coordinates of A and B, then divide by 2.

The x-coordinates are the numbers that comes first in the points.

A: (-5,3)

B: (3, -1)

The x coordinates are -5 and 3.

Add the x-coordinates.

-5+3=-2

Divide by 2

-2/2=-1

The x-coordinate of the midpoint is -1.

Y-coordinate

Add the y-coordinates of A and B, then divide by 2.

The y-coordinates are the second numbers in the points.

A: (-5,3)

B: (3,-1)

The y-coordinates are 3 and -1.

Add the y-coordinates.

3+-1=2

Divide by 2.

2/2=1

The y-coordinate of the midpoint is 1.

If the x-coordinate is -1 and the y-coordinate is 1, the midpoint is <u>(-1,1)</u>

The average maximum monthly temperature in Campinas, Brazil is 29.9 degrees Celsius. The standard deviation in maximum monthly t
velikii [3]

Answer:

3.84% of months would have a maximum temperature of 34 degrees or higher

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 29.9, \sigma = 2.31

What percentage of months would have a maximum temperature of 34 degrees or higher?

This is 1 subtracted by the pvalue of Z when X = 34. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{34 - 29.9}{2.31}

Z = 1.77

Z = 1.77 has a pvalue of 0.9616

1 - 0.9616 = 0.0384

3.84% of months would have a maximum temperature of 34 degrees or higher

The area of the surface of a circular pond is needed. A measure about the pond gives a circumference of about 47 feet. Find the
Whitepunk [10]

Answer:

55.95 ft²

Step-by-step explanation:

Circumference formula:  C = 2πr  =>  r = C / (2π)

Area formula:  A = πr²

Substituting C / (2π) for r in the above equation, we get:

               C                        47 ft

A = π( ----------- )²  =  π ( -------------- )²

              2π                       (2π)

or ...

          π(47 ft)²                   2209 ft²

A = ----------------------  =  --------------------  =  55.95 ft²

               4π²                   4(3.14159)²
