Find the mean of the following data set
73, 81, 51, 76, 89, 95, 88

Answers

Answer 1

Answer:

[tex]mean = \frac{(73 + 81 + 51 + 76 + 89 + 95 + 88)}{7} \\ = 79[/tex]

Answer 2

Answer:

79

Step-by-step explanation:

What is mean?  The mean is the same as an average. To find the mean, add all the letters together. Then, divide this sum by the total amount of numbers.

Step One: 73+ 81+51 +76+ 89+ 95+88= 553

Step Two: Divide by numbers, in this case, there are 7: 553/7= 79.

There you go!

can you please help me with this ASAP!!

Answers

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)

then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)

Now plot these two points (3,0) and (6,-1) on graph..

The distance between second and third bases on a regulation baseball field is 90 feet. Scott says he needs to multiply to find the number of yards between the second and third bases. Do you agree? Support your answer

Answers

Answer:

Yes, distance in yards can be obtained by multiplication.

Step-by-step explanation:

Given that the distance between tow points is 90 feets, The distance between these two points in yards can be obtained either by multiplication or division.

I foot = 0.3333 yards

To convert distance between the second and third bases from feet to yard ;

Multiply distance in feets by 0.3333 to obtain the corresponding distance in yards ;

90 * 0.3333 = 29.997 = 30 yards

Harrison is having a tub of yoghurt for a snack. The tub weighs 30g and holds 120ml, so he says that his snack (the tub and yoghurt together ) weighs 150g. Can you please explain why his mistake is mistaken please?

Answers

Step-by-step explanation:

Given

Tub weighs 30 g and can hold 120 ml yogurt

It is not right to simply write the ml to gm unless it is case of water

mass is given by product of volume with density

So, density of yogurt is different than water. It is not appropriate to write 120 ml to 120 gm

Thus, the claim of Harrison is wrong that his snack weighs 150 gm.

Together they swam a total of 175 laps. Swimmer B swam 25 more than twice as many laps as Swimmer A.

Answers

Answer:

75

Step-by-step explanation:

175= 25+2a

The number of laps that Swimmer A swam was 50 laps.

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Let we suppose that:

Swimmer A swam x lapsSwimmer B swam y laps.

Then, according to the given data, we have:

x + y = 175 laps

y = 25 + 2x (25 more than twice of laps of A is the number of laps of B).

Thus, we get a system of two equations as:

[tex]x + y = 175\\y = 25 + 2x\\[/tex]

From second equation, putting value of y in first equation, we get:

[tex]x + (25 + 2x) = 175\\3x + 25 = 175\\3x = 150\\\\x = \dfrac{150}{3} = 50 \: \rm laps[/tex]

As x is the number of laps Swimmer A swam, thus, the number of laps that Swimmer A swam was 50 laps.

Answer:

x=12

Step-by-step explanation:

5(x−7)=25

Divide both sides by 5.

x−7=25/5

Divide 25 by 5 to get 5.

x−7=5

Add 7 to both sides.

x=5+7

Add 5 and 7 to get 12.

x=12

Answer:

x = 12

Step-by-step explanation:

5(x-7) = 25 (distribute)

5x-35 =25 (add 35 on both sides)

5x = 60 (divide)

x = 12

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?

Answers

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

To calculate the future value, we need to use the following formula:

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12
