Answered by admin AT 20/02/2020 - 11:09 PM

By the given scenario above, we can formulate two inequalities that best represent the scenario. We let x and y be the number of tables and chairs, respectively such that,
                                 25x + 15y ≤ 285
                                  x + y ≥ 16
The values of x and y if we temporarily change all the inequality signs to equal signs are 4.5 and 11.5, respectively. Since, it is not allowed for a number of item to be in negative, we can then say that the number of tables should be 4 and that of chair is 12.

At a carnival game, you randomly throw two darts at the board and break two balloons out of 15. What is the probability that both the balloons you break are purple? Write your answer as a fraction or percent rounded to the nearest tenth. (3 red, 4 blue, 2 green, 2 yellow, 4 purple)

Add up the total number of balloons (15) there are 4 purples so the probably of you getting purple at all is 4/15. consider that after you hit the first purple, your odds decrease to 3/14.

QUESTION POSTED AT 28/03/2020 - 12:48 PM

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.

Let x be the number of songs downloaded.
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.
This cannot be more than 20, so we set this less than or equal to 20:
1.29x ≤ 20.

To solve this, we divide both sides by 1.29:
 \frac{1.29x}{1.29}  ≤  \frac{20}{1.29} ;
x ≤15.5.

We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

Space in the box = volume
volume = length x width x height
box 1 volume = 15 x 20 x 10 = 3000
box 2 volume = 15 x 20 x 14 = 4200
how much space is left = box 2 - box 1 = 1200 inches

QUESTION POSTED AT 28/03/2020 - 12:42 PM

There is a set of 100 observations with a mean of 40 and a standard deviation of 0. What is the value of the smallest observation in the set?

Answer with Step-by-step explanation:

There is a set of 100 observations with a mean of 40 and a standard deviation of 0.

standard deviation=0

means that variance=0     (since, variance=square of standard deviation)

now, variance is calculated as sum of the square of deviations of all the data points from the mean

i.e. if x1,x2,...xn are n observations, then

\dfrac{(x1-mean)^2+(x2-mean)^2+...(xn-mean)^2}{n}  is the variance

since variance is zero means that each of (xi-mean)^2 is zero

i.e. xi=mean for each i=1,2,...n

Hence here each of the observation is equal to mean=40

Hence, the value of the smallest observation in the set is:

      40

The data shows the number of grams of fat found in 9 different health bars. 11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19 What is the IQR (interquartile range) for the data? a. 6.25 b.7 c.14.5 d.17.5

Answer:

Option A. 6.25

Step-by-step explanation:

The data shows the number of grams of fat found in different health bars is

11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19

Now we will arrange the data in ascending order

10.5, 11, 11.5, 14.5, 14.5, 17, 17, 18, 19

Middle of the numbers is 14.5 which is median of the data.

We know IQR = Median of first quartile - median of second quartile

Median of first quartile = \frac{1}{2}(11+11.5)=11.25

And median of second quartile = \frac{1}{2}(17+18)=\frac{35}{2}=17.5

Now IQR = 17.5 - 11.25 = 6.25

Therefore Option A 6.25 is the correct option.
