Answer:

Mean

Step-by-step explanation:

Mean is the average of all results.

Step 1 : Identify the formula of calculating mean

Mean = <u>Sum of all data</u>

             Number of data

Step 2 : Substitute the values in the formula

Mean = <u>10 + 15 + 25 +75 + 75 + 77 + 80 +83 + 85 + 90</u>

                                        10

Mean = <u>615</u>

              10

Mean = 61.5 marks

!!

A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equatio
mamaluj [8]

Answer:

65 gallons per minute

Step-by-step explanation:

The total volume of the tank at any given time is given by the equation:

V(t) = 65t + 280

In order to find the rate of change of volume, we can simply differentiate this equation with respect to time. This will give us the rate of change of the volume or the rate at which water is being pumped into the tank.

Differentiating the above equation we get:

V'(t) = 65

So we can see that the rate at which water is being pumped into the tank is 65 gallons per minute

Ana angle measure 79.8 degrees less than the measure of it’s complementary angle what is the measure of each angle
RUDIKE [14]

Answer:

x = 129.8 degrees,  y = 50.2 degrees,    x + y = 180

Step-by-step explanation:

Let's say you have 2 supplementary angles, x and y

So x + y = 180

if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8

Putting this into our x + y = 180 equation, we get

(y - 79.8) + y = 180

2y - 79.8 = 180

2y = 180 + 79.8

2y = 259.8

y = 259.8/2 = 129.9 degrees.

so x = 129.9 - 79.6 = 50.3 degrees.

See if it worked. x = 129.9 degrees,  y = 50.3 degrees,    x + y = 180 so we found the correct two angles! :-)

Lyrx [107]

The class which generally had the highest pulse of students recorded by the science teacher after climbing the stairs is class 3.

<h3>What is box plot representation of data?</h3>

Box plot is the way of representation of data which gives the graphical image of the data set to understand better.

The minimum and the maximum values in the box plot is plotted at the end points.

  • A science teacher recorded the pulse of each of the students in her classes after the students had climbed a set of stairs.
  • She displayed the results, by class, using the box plots shown.

In this box plot, the class 3 has the highest value compare to all the box plot.

Thus, the class which generally had the highest pulse of students recorded by the science teacher after climbing the stairs is class 3.
