Based on the sequence, it shows an Arithmetic Sequence. The difference from one number to the other is 0.75. In order to get the sum of the sequence at a given N items, you need to use the formula. 

The formula is S = N/2 [2a1 + (N-1)d].
S = sum
N = number of items
a1 = first item of the sequence
d = difference from one item to the next item

The triathletes were offered water as they rode by the volunteer station. The volunteers handed them cones with the dimensions s
sladkih [1.3K]

Considering the volume of the cone, it is found that each triathlete sloshed out 9.5 cm³ of water.

<h3>What is the volume of a cone?</h3>


The volume of a cone of <u>radius r and height h</u> is given by:

V = 1/3 x r² x h

In this problem, the radius and the height are given as follows:

r = 3.5 cm, h = 7 cm.

Hence the total volume is:

V = 1/3 x 3.5² x 7 = 28.6 cm³

The triathletes sloshed out 1/3 of that, hence:

1/3 x 28.6 = 9.5 cm³.

Bond [772]

If Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Then the mean of the sample is 3.75.

<h3>What is Mean?</h3>

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency.

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week.

Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars.

Then the mean of the sample will be

\rm Mean = \dfrac{1}{N} \times \Sigma _{i}   \ \ x_if_i

Then the table is given below.

Then we have

\rm Mean = \dfrac{1}{65} \times (244)\\\\\\Mean = 3.7538\\\\Mean \approx 3.75

More about the mean link is given below.

ycow [4]

Answer:

11 bushels of apples were sold

Step-by-step explanation:

Let

x---->  bushels of peaches

y---->  bushels of apples

we know that

7x+6y=346 -----> equation A

x=y+29 -----> equation B

substitute equation B in equation A and solve for y

7(y+29)+6y=346

7y+203+6y=346

13y=346-203

13y=143

y=143/13=11
