Answer:
w > -0.4
Step-by-step explanation:
Given the inequality expression, w – 0.7 > -1.1:
First, we must isolate the variable, w, by adding 0.7 to both sides of the inequality statement:
w – 0.7 + 0.7 > –1.1 + 0.7
w > -0.4
Therefore, the correct ray is the empty circle with its ray pointing towards the right (Option 4). This implies that -0.4 is not included as an endpoint in the inequality.
Attached is a screenshot of the number line where it shows where the empty circle is located, along with the direction of the arrow.
If f(x)=1–2x + k and f(f(k)) = 13, determine the value of f(-1).
By definition of f(x),
f(k) = 1 - 2k + k = 1 - k
Then
f(f(k)) = f(1 - k) = 1 - 2 (1 - k) + k = 3k - 1 = 13
Solve for k :
3k - 1 = 13
3k = 14
k = 14/3
Find f(-1) :
f(-1) = 1 - 2 (-1) + 14/3 = 1 + 2 + 14/3 = 23/3
In a box there are 6 orange balls, 4 green balls and "x" blue balls. If the probability of drawing a blue ball is 1/3, what is the probability of drawing two blue balls?
Step-by-step explanation:
I assume it is meant to draw 2 blue balls in a row out of the full pool of balls (no other draws happen before or during this process).
tricky, your teacher.
I think the temptation is to simply say 1/3×1/3 = 1/9.
but is it ?
the probabilty to draw one blue ball out of the complete system (no ball missing) is
x / (6+4+x) = 1/3
x = (6+4+x)/3
3x = 6 + 4 + x = 10 + x
2x = 10
x = 5
so, we have a system of 6 orange, 4 green and 5 blue balls (15 all together) .
the probability at our first pull to draw a blue ball is the indicated 5/15 = 1/3.
but now, for the second ball, we have only 6 orange, 4 green and 4 blue balls in the pool (14 altogether).
and so the probability to draw a blue ball out of this is
4/14 = 2/7.
therefore, the probability to draw 2 blue balls is now the combination
1/3 × 2/7 = 2/21
aha ! so, it is a little bit less than the originally suspected probability of 1/9.

Is value of the 2 in the tenths place the same value of the 2 in the ones place?
Answer:
No.
Step-by-step explanation:
If two were in the ones place, which would look like this: 2, then you would have two of an object. So two dogs, cats, ect.
If two were in the tenths place, which would look like this: .2, then you have two thenths of an object. Not one complete object, just that amount of it.
You would not want two tenths of a sock for a present, you would want two socks.

Write the first five terms of the arithmetic sequence. a1 = 9; d = -2
Answer:
nth term = 1 1/2n -1
Step-by-step explanation:
The arithmetic sequence formula is:
a n = a 1 + ( n – 1 ) d
Where: a n
is the nth term in the sequence
a 1
is the first term in the sequence
n
is the term you are solving for
d
is the common difference for any pair of consecutive numbers in the sequence.
First Term or
n = 1 :
This is given in the problem.
a 1 = 9
Second Term or
n = 2 :
Substitute
2 for n
in the formula and substitute the values from the problem giving:
a 2 = 9 + ( ( 2 – 1 ) × -2 )
a 2 = 9 + ( 1 × -2 )
a 2 = 9 +-2
a 2 = 7
Fifth Term or n = 5 :
Substitute in the formula and substitute the values from the problem giving:
a 5 = 9+ ( ( 5– 1 ) × -2 )
a 5 = 9 + ( 4 × -2 )
a 2 = 9 + -8
a 2 = 1
Using this same process you should be able to determiner the
Third Term or n = 3
: and Fourth Term or n = 4 :

Using it's concept, it is found that the mean income in Sambala is of $87,571.43.
The mean of a data-set is the sum of all observations in the data-set divided by the number of observations.
In this problem, there are 7 observations: 35000, 46000, 68000, 300000, 57000, 41000 and 66000.
Hence, the mean is:
[tex]M = \frac{35000 + 46000 + 68000 + 300000 + 57000 + 41000 + 66000}{7} = 87571.43[/tex]

The bike you have been saving for is discounted 25%. You have $600 saved to purchase it. The original, non-discounted price of the bike is $675. There is a 5.77% sales tax added to the price of the bike. After you purchase the bike with the discount and sales tax, how much money will you have left over? Round your answer to the nearest dollar.
Answer:
65
Step-by-step explanation:
find discounted price
675*0.25=168.75
675-168.75=506.25
then add tax
506.25*1.0577=535.46(rounded)
600-535.46=64.54
Jack Is 2 times as old as lacy. 8 years from now the sum of their ages will be 61. How old are they now?
Answer:
Jack = 30
Lacy = 15
Step-by-step explanation:
Let the age of Lacy be " x ".
Jack Is 2 times as old as lacy,
Age of Jack = 2 * Age of Lacy
Therefore,
Age of Jack = 2x.
8 years from now,
the age of Jack = 2x + 8
the age of Lacy = x + 8
8 years from now the sum of their ages will be 61,
2x + 8 + x + 8 = 61
2x + x + 8 + 8 = 61
3x + 16 = 61
3x = 61 - 16
3x = 45
x = 45 / 3
x = 15
The age of Jack
= 2x
= 2 * 15
= 30 years old.
The age of Lacy
= x
= 15 years old.
Hence,
Now,
the age of Jack is 30 years old.
the age of Lacy is 15 years old.
