Melinda takes readings of the depth of water in a
pond every day for 1 week. Here are her results in
meters:
6.5, 6.8, 7.2, 6.8, 6.6, 6.3, 6.4
What are the mean, median, and mode water levels
for the week, rounded to the nearest tenth?
Answer with supporting work:

Answers

Answer:

a) The Mean of the water levels for the week (μ) = 6.657

b) The Median of the water levels for the week = 6.6

c) Mode = 6.8

Step-by-step explanation:

Step(i):-

Given that the data per one week

6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4

we have to find the mean of the given data

Solution:-

Mean = ∑x /n

[tex]Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}[/tex]

Mean = [tex]\frac{46.6}{7}[/tex]

Mean(μ) = 6.657

The Mean of the water levels for the week (μ) = 6.657

Step(ii):-

Given that the data per one week

6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4

we have to find the Median of the given data

A median is the center value of a given data when arranged in an order

6.3 6.4 6.5 6.6 6.8 6.8 7.2

The Median = middle of the given data

The Median = 6.6

Step(iii):-

Given that the data per one week

6.5, 6.8 , 7.2 ,6.8 ,6.6 ,6.3 , 6.4

we have to find the Mode of the given data

Mode = Value repeated the most number of times

The value 6.8 repeated two times

∴ Mode = 6.8

Step-by-step explanation:

50,60,72 find the 8th term airthmetic and geometric sequence

Answers

Answer:

8th term is 179.15904

Step-by-step explanation:

The sequence is geometric with a common ration = 6/5

r = 60/50 = 72/60 = 6/5

Use the formula

[tex]a_{n} = ar^{n - 1}[/tex]

In your case a = 50, r = 6/5 and n = 8

[tex]a_{8} = 50(6/5)^{8 - 1} \\ = 50(6/5)^{7} \\ = 50(279936/78125)\\ = 179.15904[/tex]

Michael runs a distance of 5 1/4 miles in 45 3/4 minutes during a fade. At this rate, what is Michaels average speed in miles per hour?

Answers

Answer: Micheal's average Speed =6.885 miles per hour

Step-by-step explanation:

Speed= Distance /time

Given the distance he ran as = 5 1/4 miles

And Time taken = 45 3/4 minutes

changing to hours becomes

60 mins = 1 hour

45 3/ 4 mins = 45 3/4 mins/ 60mins x 1hour

= 45.75 /60 = 0.7625hours

Therefore Micheal's average Speed= Distance /time

=5 1/4miles / 0.7625hours = 5.25/ 0.7625

=6.885 miles per hour

approximately 7 miles/hour.

find x and y!!!!!!!!!!

Answers

Answer:

x = 8

y = 8√3

Step-by-step explanation:

sin(30) = 1/2

cos(30) = √3/2

They are rule!!!

sin = opposite / hypotenuse

sin 30° = x / 16

16 sin 30° = x

x = 16 sin 30°

x = 8

sin 60° = y / 16

16 sin 60° = y

y = 16 sin 60°

y = 13.85640....

y = 13.9 (nearest tenth)

Write the equation 3x+2y=8 in general form. SHOW YOUR WORK PLEASE

Answers

Answer:

3x+2y-8=0

Step-by-step explanation:

The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.

What is a numerical expression?

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We are given that the equation 3x+2y=8.

The equation of straight line is written as y = mx + c

3x+2y=8.

2y = 8 - 3x

y = 8/2 - 3/2x

y = 4 - 3x/2

Hence, the general form is 3x + 2y - 8 = 0.
