What is the average (mean) of the following numbers: 2, 5, 8, and 1? Options: 4 3 5 4.5
Answers
Answer:
mean = 4
Step-by-step explanation:
the average ( or mean ) of a data set is calculated as
mean =
sum = 2 + 5 + 8 + 1 = 16
count = 4 ( number of values in data set )
substitute these values into the formula for mean
mean = = 4
Final answer:
The mean (average) of the numbers 2, 5, 8, and 1 is calculated by adding the numbers together (which gives 16), and then dividing this sum by the total number of numbers (4). So, the mean of these numbers is 4.
Explanation:
The subject of this question is Mathematics and it relates to the concept of statistical mean (average). To find the mean of the numbers 2, 5, 8, and 1, you add them all up and then divide by the number of numbers.
- First, add the numbers together: 2 + 5 + 8 + 1 = 16.
- Then, divide by the total number of numbers, which in this case is 4. 16 divided by 4 is 4.
So, the mean (average) of 2, 5, 8, and 1 is 4.

This question about converting unit forms into standard forms.
- A standard form is written in number form
- A unit form is writing a number using place value units
Let's convert ten hundredths in standard form
Thus, ten hundredths in standard form (or standard notation) is 0.1.
We call it 'one-tenth', it's a small number of less than 1.
Note:
Let's recall the place value.
Thousand | Hundred | Unit | (Decimal Point) | Tenth | Hundredth | Thousandth
Decimal point tells when starting to count. We begin with a tenth when we go to the right of the decimal point and the unit when we go to the left.
Another example:
- 21.3 is twenty-one and three tenths
- two and forty-five thousandths is 2.045
At a higher level, we also need to learn about scientific notation. Scientific notation helps us summarize the writing of very large or very small numbers.

Ten hundredths in standard form is written as 0.10.
In standard form, the decimal representation of a number consists of a whole number part, a decimal point, and a fractional part.
The fractional part represents a portion of a whole.
In the case of ten hundredths, the number 10 represents the fractional part of 0.10.
The digit 1 is in the tenths place, and the digit 0 is in the hundredths place.
Therefore, 0.10 represents ten hundredths in standard form.

The distance from one end to the other end is (D + 2D) = 3D .
3D = 1,049 miles
Divide each side by 3 :
D = 1,049 / 3 = 349 and 2/3 miles .
The question doesn't tell which end he started from, and where he's headed,
so I guess you have to know that this is the Iditerod race, it STARTS in Anchorage,
and it ENDS in Nome.
He is ' 2D ' from Anchorage, so he has completed [ 2 x (349 and 2/3 miles) ] =
699 and 1/3 miles.
Rounded to the nearest mile, that's 699 miles.
b. what is the maximum height the ball will reach
c. find the number of seconds the ball is in the air when it reaches 224 ft in height
d. after how many sec. will the ball hit the ground before rebound?
I am not sure which equation to use and why for the b,c,and d. If I find the ft/sec. that the ball travels (96), and set the quadratic equation to -16t^2+144t+288 or 16t^2-144t-288=0, is this correct? Or should I use the quad formula and why.
Answers
the maximum height of the ball will be where the derivative is zero. In other words you could find the height of the ball by converting this into vertex form, or you could find it by calculating the time needed for the ball to reach its maximum height.
0=-32t+144
t=3 till max and max is 288
224=-16t^2 +144t
0= -16t^2+144t-224
t=2 but then the ball will reach 224 ft again at t=7
the ball reaches its maximum height at t=3 seconds and a parabola is symmetric, so at t=6 seconds it will contact the ground again.

, where P is the power in watts and R is the resistance in ohms.How many more volts are needed to light a 100-watt light bulb than a 75-watt light bulb if the resistance of both is 110 ohms? Round answer to the nearest tenth.
Answers
Answer:
✓11000-✓8250=~ 14 volts
Step-by-step explanation:
the answer is the difference by 100-watt light bulb to a 75 light bulb.
so, all you have to do is this:
v1-v2--------> ✓PR-✓P2R2
so you'll have ✓100.110-✓75.110= ✓11000-✓8250= 14
I hope it helps
Final answer:
By using the formula v=√PR, it is calculated that approximately 13.8 more volts are needed to light a 100-watt bulb than a 75-watt bulb, both having a resistance of 110 ohms.
Explanation:
To find out how many more volts are needed to light a 100-watt light bulb than a 75-watt light bulb, the amount of voltage required for each bulb is to be calculated using the given formula v= √PR, and then subtracted to find the difference.
For voltage required to light a 100-watt bulb:
v100= √(100W * 110 ohms) = 105.4 volts
For 75-watt bulb:
v75 = √(75W * 110 ohms) = 91.6 volts
The difference in voltage:
v100 - v75 = 105.4V - 91.6V = 13.8V
So, approximately 13.8 more volts are needed to light a 100-watt bulb than a 75-watt bulb, when rounded to the nearest tenth.
