pls help i always was the worst at this

Answer:

11cm

Step-by-step explanation:

Hi, I can help.

Now to find this it is just simple subtraction but you need to know what to look for.

Let us first imagine that the top rectangle sticking out doesn't exist. Lets focus on the bottom rectangle who has the dimensions of 6 and 18cm. We need to find the ? on the top of the rectangle.

Now lets add the top rectangle. Something important to remember is that the 5cm top lines up with the ? even though it is above it.

Also, the top and bottom of a rectangle is always to going to match up / be equal.

So the 5cm + ? is going to be equal to 16cm.

So how can we use this info to find the answer? We can actually look at the 16cm and 5cm. Since the 16cm and the 5 + ? are equal we can take the 16cm at the bottom and actually take away 5cm away from it to find the ?.

So :

16cm - 5cm = 11cm

So literally that is it.

11cm is your ?

Isabelle is plotting a pentagon on a grid. So far, she has plotted and connected the three points shown on the grid below. To complete the pentagon, she can choose only from the points below. (2, 0), (–2, 0), (–2, 4), (2, 4) How can Isabelle complete her pentagon? Connect the point already at (0, –2) to a new point at (2, 0), and then connect ( 2, 0) to (–2, 4). Connect the point already at (0, –2) to a new point at (–2, 0), and then connect ( –2, 0) to (–2, 4). Connect the point already at (0, –2) to a new point at (–2, 0), connect ( –2, 0) to (2, 4), and then connect (2, 4) to (–2, 4). Connect the point already at (0, –2) to a new point at (2, 0), connect (2, 0) to (2, 4), and then connect (2, 4) to (–2, 4).

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83

Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.

Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.

Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?
