Answer: Option b

Step-by-step explanation:

There is an outlier of 24 which will significantly increase the value of mean. So, do not use mean when there is an outlier.

To find median, first of all you should arrange the numbers in ascending order. The central value will be 4.

Mika bought 9 rolls of film to take 180 pictures on a field trip. Some rolls had 36 exposures and the rest had 12 exposures. How

Juli2301 [7.4K]

The number of each type Mika bought =x = 6.8 rolls; y= 2.2 rolls.

<h3>Calculation using ratio</h3>

The number of rolls of film Mika bought = 9 rolls

The number of rolls that had 36 exposures = x

The number of rolls that had 12 exposures = y

The total number of exposures = 36 + 12 = 48

To find the exposure by one roll = 48/9 = 5.3

If one roll = 5.3 exposure

x roll = 36 exposure

Make x roll the subject of formula,

x roll = 36/5.3 = 6.8 rolls

If one roll = 5.3 exposure

y roll = 12 exposure

Make y roll the subject of formula,

y = 12/5.3 = 2.2 rolls

Therefore, the number of each type Mika bought = x = 6.8 rolls; y= 2.2 rolls.

PLEASE HELP! A tank containing 35 gallons of water is leaking at a rate of 1/4 gallon per minute. Write an expression to determi

Alekssandra [29.7K]

Answer:

35 - m is the expression used to determine the number of gallons left in the tank after m minutes.

Step-by-step explanation:

Given:

Tank with 35 gallons of water is leaking at a rate of gallon per minute

Calculations:

Let "m" represent the number of minutes spent
Number of gallons left in the tank = initial amount of water present – leaked amount of water
$=35-m * 1=35-m$
The required expression is 35 – m

Which equation correctly shows how to determine the distance between the points (9, –2) and (6, 3) on a coordinate grid?

Dmitry [639]

Answer: $d=\sqrt{(6-9)^2+(3-(-2))^2}$ (Third option)

Step-by-step explanation:

The formula for calculate the distance (d) between two points is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given the points (9,-12) and (6,3), you can identify:

$x_2=6\\x_1=9\\y_2=3\\y_1=-2$

Substitute these coordinates into the formula $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ to find the equation that correctly shows how to determine the distance between the given points (9,-12) and (6,3).

Then:

$d=\sqrt{(6-9)^2+(3-(-2))^2}$ (Third option)
