Step-by-step explanation:

Step 1: Find the median

The median on the box-and-whisker plot is the line that is inside of the box. On this plot, the median is 11 since it is where the line is.

Step 2: Find the range

The range on a box-and-whisker plot is the difference from the largest point and the smallest point. On this plot, the largest point is 19 and the smallest point is 7. So, subtract 7 from 19 and you get that the range is 12.

Step 3: Find the 25th percentile

The 25th percentile on a box-and-whisker plot is the left side of the box object. On this plot, the 25th percentile is 9.

Step 4: Find the 75th percentile

The 75th percentile on a box-and-whisker plot is the right side of the box object. On this plot, the 75th percentile is 14.

Step 5: Find the inter-quartile range

The inter-quartile range on a box-and-whisker plot is the difference between the 75th percentile or right side of the box and the 25th percentile or the left side of the box. On this plot, the 75th percentile is 14 and the 25th percentile is 9. So, subtract 9 from 14 and you get that the inter-quartile range is 5.

Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 1 : 4 : 7 by weight. Henry needs

jolli1 [7]

Answer:

Henry is short of gravel

Step-by-step explanation:

Here, we are to identify which of the ingredients Henry is short of.

To identify this ingredient, what is needed to be done is to share the 180kg of concrete appropriately to get which of the material does not meet its ratio and thus allowing us know which is insufficient.

The total ratio is 1 + 4 + 7 = 12

For cement, we have ;

1/12 * 180 = 15 kg

For sand, we have

4/12 * 180 = 60kg

For gravel, we have

7/12 * 180 = 105 kg

From the values in the question, we can see that all the values we have are greater what is shared in the ratio except in the case of gravel. So we can confidently say he is short of gravel

Find the area of the circle to the nearest tenth. Use 3.14 for it (11 mm)

Nikolay [14]

Answer:

The area of the circle is 379.94 mm²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 11 mm

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (11 mm)²

a = 3.14 * 121 mm²

a = 379.94 mm²

Round to the nearest tenth

a = 379.94 mm² = 379.9 mm²

The area of the circle is 379.9 mm²

A ship traveling east at 45 mph is 15 mi from a harbor when another ship leaves the harbor traveling east at 60 mph. How long do

Harman [31]

Answer:

1 hour

Step-by-step explanation:

I find these easiest to work by considering the initial difference in distance and the speed at with that gap is closing.

The gap is 15 miles, the distance the first ship is from harbor when the second ship starts.

The rate of closure is the difference in the speeds of the two ships:

60 mph -45 mph = 15 mph

Then the closure time is ...

time = distance/speed

time = (15 mi)/(15 mi/h) = 1 h

It will take the second ship 1 hour to catch up to the first ship.
