Answer:

3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}

Step-by-step explanation:

Given

See attachment for number line

Required

Determine the model

From the attachment, we can see that each partition is 1/3

The gray rectangle covers 11 partitions.

So:

Gray = 11 * \frac{1}{3}

Gray = \frac{11}{3}

Express as a mixed number

Gray = 3\frac{2}{3}

The black rectangle covers 8 partitions

So:

Black= 8 * \frac{1}{3}

Black= \frac{8}{3}

Express as a mixed number

Black= 2\frac{2}{3}

So, the model is:

Gray + Black = Total

Where Total is the point where the black rectangle stops

3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}

Supposed Blue spruce was included in the list and the mean decreased to 165 what is the height of the Blue spruce?
postnew [5]
The height of the blue spruce was 45.

We find the mean by adding all of the data points and dividing by the number of data points.  We will add the unknown value x and change the number we're dividing by to 7:

(160+320+100+110+200+220+x)/7 = 165
(1110+x)/7 = 165

Multiply both sides by 7:
1110 + x = 1155

Subtract 1110 from both sides:
x = 45

Neko [114]
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92

This would just look like a bar graph.

On the horizontal axis, put your 4 different categories of 2, 3, 4, or 5.

On the vertical axis, label it by the percents: 0.10, 0.20, 0.30, 0.40

Then, make a bar at the correct height for each category.
