Find the mean, median, mode and range for the following data set. 1, 3, 5, 9, 8, 5, 8, 6
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and How to solve:-}}}[/tex]
In order to find the mean of a data set, we add all the numbers in the data set and add them, then we divide by how many there are:-
1+3+5+9+8+5+8+6
[tex]\bigstar[/tex] On simplification,
18+8+5+8+645[tex]\bigstar[/tex] Now, divide by 8, because there are 8 numbers in the data set:-
[tex]\bold{\dfrac{45}{8}\:;written\:as\:decimal\Longrightarrow5,625}}}[/tex]
We've found the mean, but we also need to find the median, mode, and range!
The median is the number in the middle, but we should first arrange the data from least to greatest:-
1, 3, 5, 5, 6, 8, 8, 9
Now pick the number in the middle, which is:-
5,6. There are 2 numbers in the middle!
So what we do is we find the mean of the two numbers in the middle:-
5+6=11
11/2 [tex]\Longleftarrow[/tex] median
Now, we don't need to find the mean anymore - the mode and range don't require the mean.
The median requires the mean only when there's an even amount of numbers in the data set.
The mode of a dataset is the number we see the most.
Here we see the number 1 once, the number 3 once, the number 5 appears twice, 6 appears one time only, 8 appears twice and, last but not least, 9 appears once.
So this data set has two modes - 5 and 8.
In order to find the range, we take the smallest number (1) and subtract it from the largest number (9), which results in
8 (range)
Good luck with your studies.[tex]\rule{300}{1}[/tex]

State the domain and range of: y = arcsin (x²)
Answer:
Domain is -1 ≤ x ≤ 1.
Range is 0 ≤ y ≤ π/2.
Step-by-step explanation:
The arcsin only exists for -1 ≤ x ≤ 1 so this domain is
-1 ≤ x ≤ 1.
When x = 1 or -1 , y = arcsin(1^2) = π/2
When x = 0 , y = 0.

To find the number of bowls needed divide total tomatoes by tomatoes each bowl can hold.
Solve:
16 ÷ 3 = 5.333...
So, we need more than 5 bowls, [6 bowls] to hold the tomatoes.
Answer:

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. How many more calories from fat are provided by a 100- calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels?
Answer:
50 calories
Step-by-step explanation:
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:
= 90/150 = 3/5
One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:
= 12/120 = 1/10
The fat that are provided by a 100 calorie serving of the microwave popcorn would be:
= 3/5 × 100
= 60
The fat that are provided by a 100-calorie serving of the pretzels would be:
= 1/10 × 100 = 10
The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:
= 60 - 10
= 50 calories

What is the length of DE?
Answer:
D. 6
Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE
12/8 = 9/x cross multiply expressions
12x = 72 divide both sides by 12
x = 6
what’s the answer to this problem , figure out the area and perimeter of this triangle
Answer:
A: 0.3318 m^2 P: 2.66
Step-by-step explanation:
The perimeter is only adding each of the side lengths, so that's not much of an issue. The equation for the area of a triangle is A = (b x h)/2, with "b" being the base length and "h" representing the triangle's height. We must first multiply the base and height, 0.84 x 0.79. This makes 0.6636 which we will then divide by 2. Our area is now proven to be 0.3318 square meters.
write each equation in slope-intercept form.
1. 3x = -8 + y
2. 9 = 3x + 3y
3. 4y – 10 = 20x
[tex]\text{Slope- intercept form is y =mx+c, where m is the slope and c is the y-intercept.}\\ \\\textbf{1)}\\\\~~~~~3x = -8+y\\\\\implies y = 3x +8\\\\\textbf{2)}\\\\~~~~~9=3x+3y\\\\\implies 3y= 9-3x\\\\\implies y= \dfrac 13(9-3x)\\\\\implies y= 3-x\\\\\implies y= -x+3\\\\\textbf{3)}\\\\~~~~~~4y-10 = 20x\\\\\implies 4y = 20x +10\\\\\implies 2y = 10x +5\\\\\implies y = \dfrac 12(10x +5)\\\\\implies y= 5x +\dfrac 52[/tex]

urgent!! Write a number that is greater than -7.81 and less than -7 .
Answer:
-7.6
Step-by-step explanation:
there are many correct answers for this problem
The number that is greater than -7.81 and less than -7 is -7.41. This can be written as -7.81 < -7.81 < -7. This is obtained by taking the midpoint or middle integer of the given integers.
How to find integers between two integers:Firstly add the two integers with respect to their signThen divide the result by 2. that is nothing but taking its average.This results in the integer which is in between the given integers.Calculation:Given that a number that is greater than -7.81
so, we can write -7.81 <?
And it is also given that the same number which is less than -7. we can write it as -7 >?
So, from this two we can state that the number which is required lies in between the given two integers.
so, we can write -7.81 <?< -7
To find this, we are applying the average for the two integers.
⇒ -7.81 - 7 = -14.81
⇒ -14.81/2 =-7.405 ≅ -7.41
The obtained number satisfies the given conditions
-7.81 < -7.41 and -7 > -7.41
Therefore, the required number is -7.41.

Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their ages is 92. Witch could be used to find Hannah's age, h if she is the older sibling?
Answer:
The equation to find Hannah's age is 2h - 2 = 92.
This yields Hannah's age as 47 years.
Step-by-step explanation:
Let h = Hannah's age.
Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age = h-2.
The sum of their ages is 92, therefore
h + (h-2) = 92
2h - 2 = 92
2h = 94
h = 47 years

What line would be perpendicular to y − 3=4(x+2)?
A. y − 3=−4(x+2)
B. y − 3=1/4(x+2)
C. y − 3=−1/4(x+2)
D. y − 3=4(x+2)
The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)
When are two lines said to be perpendicular?Two lines are said to be perpendicular if the product of their gradient is -1.
which means m1 x m2 = -1
Analysis:
y - 3 = 4(x+2)
y = 4x + 8+3
y = 4x + 11 m1 = 4
so m1 x m2 = -1
m2 = -1/4
so from the options, the equation with a gradient x = -1/4 is C, y-3 = -1/4(x+2)
In conclusion, the line that would be perpendicular to y - 3 = 4(x+2)
