Answer:

a) 4.33 (three repeating)

b) 3.5

c) 3

d) 0.44

Step-by-step explanation: Mean is all the numbers added up and divided by the amount of items. All the items added together are 78. We have 18 items 78/18 = 4.3 (three repeating). Median is just the middle value. This is between 3 and 4 so 3.5. Mode is the one that shows the most. This is 3. 8 students play games for more than 4 hours. 8/18 = 0.44

Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the
Zanzabum

Answer:

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule R(O,90^\circ)\circ r_{y=-x}(x,y). Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to r_{y=-x}(x,y), we get

(x,y)\rightarrow (-y,-x)

According to R(O,90^\circ), we get

(x,y)\rightarrow (-y,x)

The rule R(O,90^\circ)\circ r_{y=-x}(x,y) means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

K(4,7)\rightarrow K'(-7,-4)

After rotation, we get

K'(-7,-4)\rightarrow K''(4,-7)

Therefore, the correct option is C.

The cost of a taxi ride is equal to $3.50 plus $0.25 for each mile. If a ride costs a total of $6.75 how long was the ride?
jeka57 [31]

Answer:

13 miles

Step-by-step explanation:

Write and solve an equation involving this information, using x as the distance traveled, in miles:

Cost(x) = $6.75 = $3.50 + ($0.25/mile)x

First, subtract $3.50 from both sides, obtaining:  $3.25 = ($.25/mile)x.

Next, divide both sides by $0.25/mile:

        $3.25

x = ------------------ = 13 miles

      $0.25/mile

The length of the taxi ride was 13 miles.
