Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.

What is the mean number of minutes spent on the phone?

Answers

Answer: 31

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?

Answers

Answer:

1/6 of a chance aka 16.666?%

Step-by-step explanation:

The probability of drawing a card with number 7 is 0.166.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

From the given set of cards,

Total number of cards =6

Number of spades = 3

Number of card with number 7 on it = 1

Probability of drawing a 7 = 1/6

= 0.166

Therefore, the probability of drawing a card with number 7 is 0.166.

mr. Duncan just had his condo appraised to find out its value. According to the appraiser, the
ondo is currently worth $202,470. That is 2% higher than the condo was worth when he
ought it several years ago. What was the value of the condo then?

Answers

Answer:

The appraiser said that the condo is currently worth $202,470 and it's 2% higher than the condo was worth when Mr. Duncan bought it several years ago. To find the value of the condo when he bought it, we need to subtract 2% of the current value from the current value.

We can find 2% of the current value by multiplying it by 0.02:

$202,470 x 0.02 = $4,049.4

To find the value of the condo when he bought it, we need to subtract $4,049.4 from the current value:

$202,470 - $4,049.4 = $198,420.6

Therefore, the value of the condo when Mr. Duncan bought it was $198,420.6

The answer is 194,420.6

Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.

How to calculate the circumference of a circle?

To calculate the circumference of a circle we must apply the following formula:

2$\pi$RR = Radius of the circle.

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

2$\pi$1 = 6.282$\pi$2 = 12.59

So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

12.59 - 6.28 = 6.31

According to the above, the difference of the circumferences would be 6.31 cm.

How to calculate the area of the circle?

To calculate the area of the circle we must apply the following formula.

A =$\pi r^{2}$

r = radio del círculo.

According to the above, the radiO of both circles would be:

$\pi 1^{2}$ = 3.14$\pi 2^{2}$ = 25.13

photo 3:

b. 82

photo 4:

a. 51

b. 129

photo 5: x = 60

Step-by-step explanation:

The interior angles of a triangle are the angles that are inside the triangle and are formed by the intersection of two sides of the triangle. In a triangle, there are always three interior angles.

The sum of the interior angles of a triangle is always 180 degrees. This is because the interior angles of a triangle are supplementary, meaning that they add up to 180 degrees.

Vertical angles are two angles that are opposite each other and are formed by two intersecting lines. The lines that intersect to form the vertical angles are called "arms" of the angles.

Vertical angles are always congruent, which means that they have the same measure

Complementary angles are two angles whose measures add up to 90 degrees. In other words, if two angles are complementary, then one angle is the complement of the other.

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, if two angles are supplementary, then one angle is the supplement of the other.

How can I find the cube root of 64?

Answers

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
