Because rectangles' sides are equal two by two. they are not all congruent

so the shape is a square

Joanna set a goal to drink more water daily. The number of ounces of water she drank each of the last seven days is shown below.

hammer [34]

Answer:

The median amount of water is higher when the eighth day's amount is included in the data.

Explanation:

Given the ounces of water drank is 60, 58, 64, 64, 68, 50, 57

Arranging in ascending order: 50, 57, 58, 60, 64, 64, 68

Calculating the median of the above data

Median (when n is odd) = $\left(\frac{n+1}{2}\right)^{t h} \text { term }$

where n =7

Median = 4th term = 60

When the eight day is added,

Series will be: 50, 57, 58, 60, 64, 64, 68, 82

Median (when n is even) = $\frac{\left(\frac{n}{2}\right)^{t h} t e r m+\left(\frac{\pi}{2}+1\right)^{t h} t e r m}{2}$

Median = $\frac{60+64}{2}=62$

So, here we can say that median has increased after adding 82 in the data

1. If a function f(x) is shifted to the left one unit, what function represents the transformation?

Vaselesa [24]

The correct answers are: 
1) A;
2) A;
4) D
3 cannot be done because the graph is not shown.

Explanation: 
1) Shifting a graph to the left, we would normally think of subtracting 1 from the function. However, horizontal translations are the opposite; left means adding 1 to x, while right means subtracting 1 from x.

2) A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.

4) To perform a vertical stretch of a function, we multiply by the factor; this gives us y=6x.
