Can you help me with my math

The points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5) reflected in the x-axis followed by the y-axis are (−4,−5), (1,−7), (2, 2),

Triss [41]

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> rotation, reflection, translation and dilation.</em>

If a point A(x, y) is reflected along the x axis, the new point is A'(x, -y). If a point A(x, y) is reflected along the y axis, the new point is A'(-x, y).

Given the points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5). If it is reflected along the y axis it gives (-4, 5), (1, 7), (2,−2), and (-6.5,−10.5). If it is then reflected along the x axis it gives (-4, -5), (1, -7), (2, 2), and (-6.5, 10.5).

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

A population has parameters

Ket [755]

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

Mary used Delicious (d) and Golden Delicious (g) apples to make homemade applesauce. Delicious apples are $0.75 each and Golden

alina1380 [7]

Answer:

Mary bought 9 Golden Delicious apples

Step-by-step explanation:

This can be solved by setting up a system of equations. Based on the information given, the equations would be set up as follows.

$.75d+1.25g=21.00\\d+g=22$

I prefer to solve using substitution, but elimination can be used as well

$.75d+1.25g=21.00\\g=22-d$

We can now plug in this g value to the first equation

$.75d + 1.25 (22-d)=21.00\\.75d + 27.5-1.25d=21\\27.5-0.5d=21\\-.5d=-6.5\\d=13$

This means mary bought 13 delicious apples. She bought 22 apples in total, so the total number minus the amount of delicious apples will give us the amount of golden delicious apples.

22 - 13 = g

9 = g
