Answer:

T(x, y) = (x - 5, y - 6)

Step-by-step explanation:

The transformation T is a translation that creates an image P' of original point P by adding 5 to the x-coordinate and 6 to the y-coordinate of the original point P.

Now you want to transform point P' into point P, so you are undoing the first transformation. You need to do the opposite of what the transformation above does. You need to subtract 5 from the x-coordinate and subtract 6 from the y-coordinate.

Answer: T(x, y) = (x - 5, y - 6)

What is normal, when it comes to people's body temperature? a random sample of 130 human body temperatures, provided by allen sh

nikitadnepr [17]

The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".
The test statistic is:
$Z= \frac{\bar{X}-\mu}{ \frac{s}{ \sqrt{n} } }} =-5.47$
Using an inverse normal table, and halving $\alpha$ for a two-tailed test, we look up $p=0.5-\alpha/2=0.5-0.005=0.495$ and find the critical value to be Z = 2.5758.
Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.

60 POINTS!!!

A) The IQR is Q3 - Q1 Q3 is the right edge of the blue box and Q1 is the left edge.

IQR = 25-1 = 24

B) Median values are the line inside the blue boxes:

20-5 = 15

C) the male distribution is asymmetrical and the female distribution is more symmetrical. Because the men are asymmetrical it would be best to describe the distribution using the Median. The women are symmetrical so it would be best to use the mean.

Overall the mean is the most popular/ best way to measure the center.

D) the outlier could be the first day the movie was shown

PLS HELP!

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

$Diagonal=\sqrt{length^2+width^2}$

$Diagonal=\sqrt{(50)^2+(55)^2}$

$Diagonal=\sqrt{2500+3025}$

$Diagonal=\sqrt{5525
}$

On further simplification, we get

$Diagonal=74.3303437$

$Diagonal\approx 74.3$

Therefore, the length of the required fencing is 74.3 yards.

An urn contains 9 black and 8 pink balls. Five balls are randomly drawn from the urn in succession, with replacement. That is, a

m_a_m_a [10]

Answer:

0.0416

Step-by-step explanation:

Given :

Number of balls :

Pink = 8 ; black = 9

Total number of balls = 8+9 = 17

Choosing with replacement :

Probability = required outcome / Total possible outcomes

Required outcome = number of black balls

Total possible outcomes = total number of balls

P(black) = 9/17

Number of picks = 5

Hence, Probability that all 5 picks are black :

P(all black) = 9/17 * 9/17 * 9/17 * 9/17 * 9/17 = 0.0415879

= 0.0416
