Answer:
0.9
Step-by-step explanation:
Given that data:
x : 7, 5, 11, 8, 14, 19, 16, 15, 13, 27
Mean = Σx / n
Using calculator :
Mean (m) = 13.5
Standard deviation (s) = 6.433
Proportion that lies in mean ± 2s
Lower = Mean - 2s
13.5 - 2(6.433) = 0. 632
Upper = Mean + 2s
13.5 + 2(6.433) = 26.376
Mean ± 2(sd) = (0.632, 26.276)
The only digit from the data which falls outside the defined range = 27
Proportion within interval = 9 / n
Proportion which falls within range = 9/10 = 0.9

What is the solution to the equation? 36x-20=160
Answer:
x=5
Step-by-step explanation:
36x-20=160
first, find the value of x
add 20 from both sides
36x-20=160
+20 +20
36x=180
then, divide 36 from both sides to get x by itself
36x/36=140/36
x=5
now, plug x into the equation to check your work
36(5)-20=160
multiply 36 and 5
180-20=160
subtract 20 from 180
180-20=160

g How many hours would it take to read a book that you tend to read at a rate of 1.26 pages per minute, if it is 911 pages long
Answer: It will take about 19 hours to read the book.
Step-by-step explanation:
Given: Rate of reading = 1.26 pages per minute
Total pages = 911 pages
Time taken to read = (Rate of reading ) x (Total pages to read)
= 1.26 x 911 minutes
= 1147.86 minutes
[tex]=\dfrac{1147.86}{60}[/tex] hours [ 1 hour = 60 minutes]
= 19.131 hours
hence, it will take about 19 hours to read the book.
Solve for x. X^2 = 1/4. Look at the picture for answer choices. Don't answer if you dont know.
Answer:
x is equal to ± 1/2
Step-by-step explanation:
To find x, we simply need to take the square root of both sides:
x² = 1/4
√(x²) = √(1/4)
x = √(1/4)
x = ± 1/2

You know that Mike gets paid $45 for 3 hours and $105 for 7 hours. How much money will Mike make if he babysits for 8.5 hours?
Answer:
$127.50

$45/3 = $15 per hour
$15 x 8.5 = $127.50
Answer:
127.50 dollars
Step-by-step explanation:
He makes $15/an hour because $45/3 = $15. 15 x 8.5 = $127.50.
Зу - 2(5y - 7) = -9y + 6
Answer:
y = -4
Step-by-step explanation:
3y - 2(5y - 7) = -9y + 6 (Given)
3y - 10y + 14 = -9y + 6 (Distribute)
-7y + 14 = -9y + 6 (Add like terms)
2y + 14 = 6 (Add 9y on both sides)
2y = -8 (Subtract 14 on both sides)
y = -4 (Divide 2 on both sides)
You can check by substituting the solution for y:
3(-4) - 2(5(-4) - 7) = -9(-4) + 6
-12 - 2(-20 - 7) = 36 + 6
-12 - 2(-27) = 42
-12 + 54 = 42
42 = 42
• Mother has 40 guavas to share among her daughters, Naomi got 3
more than Sharon and Kassy got 10 more than Naomi. Find each
child's share
Answer:
Step-by-step explanation:
As given Total Guavas = 40 ,
3 daughters,
Let share of Sharon = x
then by given condition ,
Naomi share = x+3 (3 more then Sharon
Also Kassie share = x+3+10 =x+13 (10 more then Naomi
Now
total shared = total
Naomi + Sharon + Kassie = 40
(x+3) +(x) +(x+13) =40
adding like terms with like we get ,
3x+16=40
3x=40-16
3x=24
x= 24/3
x= 8
hence Sharon share = x =8
Naomi share = x+3 =8+3 =11
Kassie share = x+13 = 8+13 = 21

3.3. Shuffle a deck of cards and turn over the first card. What is the probability that the first card is a
Answer:
P(H) = 13 ÷ 52
Step-by-step explanation:
The computation of the probability that the first card be the heart is given below:
We assume that each and every card in the deck would be likely to be the first card
Here we assume the Hi that represent the first card drawn be the heart
NOw
P(Hi) = 1 ÷ 52 for
1 < = i < =13.
The H event would be represent as the disjoint union
H = H1 U H2 U.....U H13
P(H) = 13 ÷ 52

Expression equivalent to 8p-3n+4q-9m
Answer:
4p-n+2q-3m is equivalent to 8p-3n+4q-9m
The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question following:
8p - 3n + 4q - 9m
We have to determine the equivalent expression to the given expression
As per option (C), we have
⇒ 4(2p+ q) - 3(n+3m)
Apply the distributive property of multiplication,
⇒ 4 × 2p+ 4 × q - 3 × n + 3 × m
⇒ 8p + 4q - 3n + 3m
Rearrange the terms in the above expression,
⇒ 8p - 3n + 4q - 9m
So this expression is the same as the given expression.
Therefore, the expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression.

An artist is making a mosaic using glass
tiles. He uses a total of 600 tiles.
The ratio of red tiles to blue tiles is 1:2.
How many red tiles does he use?
Answer:
200
Step-by-step explanation:
Let x and 2x be the number of red tiles and blue tiles respectively.
x + 2x = 600
3x = 600
=> x = 200
No. of red tiles = 200
No. of blue tiles = 2(200) = 400
