Answer:

Dilate Circle A by a scale factor of 3

Step-by-step explanation:

Circle A has a radius of 3, Circle B has a radius of 9. By dilating Circle a by a scale factor of 3, it will make it the same size as Circle B, showing that the two circles are similar.

Rotating and reflecting does nothing because both circles are in the same quadrant and rotating a circle does nothing to the placement.

Translating the circle (x+3, y-2) does not put it in the same place as circle B.

jonny [76]

Answer:

520 out of 800 students ride the bus

Step-by-step explanation:

Given

Proportion = 65\%

Students = 800

Required

Determine the number of students that\ ride\ the\ bus

To do this, we simply multiply the proportion by the total number of students.

i.e.

Bus = Proportion * Students

Bus = 65\% * 800

Express the percentage as decimal

Bus = 0.65* 800

Bus = 520

Find Mean, Median, mode and range. Round to the nearest tenth.
stiv31 [10]

Answer:

  • Mean = 26.24
  • Median = 27
  • Mode = 32
  • Range = 38

Step-by-step explanation:

Plotting the original data from leaf plot

9,11,12,12,14,17,25,25,27,32,32,32,33,35,41,42,47

<em><u>Finding Mean:</u></em>

The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:

                                                            \mu=\frac{446}{17}

                                                                = 26.24

Therefore, the range = 26.24.

<u>Finding Median:</u>

The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.

Ordering the data from least to greatest, we get:

9   11   12   12   14   17   25   25   27   32   32   32   33   35   41   42   47  

So, the median is 27 .

<em><u>Finding Mode: </u></em>

The mode of a set of data is the value in the set that occurs most often.

Ordering the data from least to greatest, we get:

9   11   12   12   14   17   25   25   27   32   32   32   33   35   41   42   47

We see that the mode is 32.

<em><u>Finding Range:</u></em>

The range is the difference between the highest and lowest values in the data set.

Ordering the data from least to greatest, we get:

9   11   12   12   14   17   25   25   27   32   32   32   33   35   41   42   47

The lowest value is 9.

The highest value is 47.

The range = 47 - 9 = 38

Please explain it step by step I dont get it.
Ivenika [448]
So, we’re looking for the amount of money Tom needs to spend to get his free meal.
X + 30.25 >
X > 9.75

X is the additional amount that Tom needs to spend. You subtract 30.25 on both sides in order to solve for x.

So, your answer would be at least $19.75
