We want to get the probability of selecting an orange, putting it back, then selecting a block that is not orange.
We will see that the probability is P = 0.1799
In the bag we have:
6 yellow blocks4 orange blocks2 green blocks5 blue blocks.For a total of 6 + 4 + 2 + 5 = 17 blocks.
First we want to find the probability of getting an orange block, as all the blocks have the same probability of being randomly drawn, the probability of randomly drawing an orange block is equal to the quotient between the number of orange blocks and the total number of blocks.
We get:
p = 4/17
Now we put the orange block back and we want to take a block that is not orange, the probability is computed in the same way:
q = (6 + 2 + 5)/17 = 13/17
The joint probability (this is, the probability of these two events happening together) is just the product of the individual probabilities.
We get:
P = p*q = (4/17)*(13/17) = 52/289 = 0.1799

The heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively. What is the height of Roger if the mean of all of them is 158cm?
Answer:
The height of Roger is 158cm
Step-by-step explanation:
All of them=158cm
They are 4.So,158^4=632cm
Height of 3 persons=155cm+158cm+161cm=474cm
Therefore the height of Roger is 632cm-474cm=158cm
The height of Roger with the mean of all of them is given is 158 cm.
Given that, the heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively.
What is mean?In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Let the height of Roger be R.
Mean= 158 cm
We know that, mean =Sum of all the observations/Number of observations
⇒ (155+158+161+R)/4 =158
⇒ 474+R=632
⇒ R=632-474
⇒ R=158 cm
Hence, the height of Roger with the mean of all of them is given is 158 cm.

5 = t + 12
please help me for this
Answer:
t = -7
Step-by-step explanation:
You have to get t by itself. Just take the 12 and subtract it from both sides. 5-12 on the left and 12-12 on the right. You then end up with -7 = t or t = -7.
can someone help me?
Step-by-step explanation:
a)
a whole circle represents always 360 degrees.
we see the angle J is 72 degrees. the angle K is 90 degrees.
that leaves us for M and L together :
360 - 72 - 90 = 198 degrees.
we now know that twice as many people voted for L as for M. that means the angle L is twice as big as the angle M
on other words : L = 2M
and when we now say
198 = L + M
this means
198 = 2M + M = 3M
M = 66 degrees
and L is then 2M = 2×66 = 132 degrees
b)
again, the whole circle is 360 degrees.
J covers 72 of these 360 degrees.
that is 72/360 of all voting people.
72/360 = 1/5
the total of all voting people was 15840.
so, 1/5 of 15840 is
15840/5 = 3168
that means 3168 people voted for J.

m∠1 AND m∠2
Answer choices for m∠1:
50, 110, 70, 90
Answer choices for m∠2:
70, 110, 40, 140
Answer:
70°, 140°, 50°
Step-by-step explanation:
110° and the angle inside the triangle are adjacent angles and sum to 180°, so
angle inside triangle = 180° - 110° = 70°
The triangle on the left is isosceles ( 2 congruent sides ) then base angles are congruent
∠ 1 = angle inside triangle = 70°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 2 is an exterior angle of the triangle on the left, so
∠ 2 = 70° + 70° = 140°
∠ 2 is also an exterior angle of the triangle on the right, so
∠ 3 + 90° = 140° ( subtract 90° from both sides )
∠ 3 = 50°

Which of the following values makes the equation
4x − 8 = −4 true?
−3
−1
1
3
Work Shown:
4x - 8 = -4
4x = -4+8
4x = 4
x = 4/4
x = 1
To check the answer, we replace x with 1 in the original equation. After simplifying, we should get the same thing on both sides
4x - 8 = -4
4(1) - 8 = -4
4 - 8 = -4
-4 = -4
The answer is confirmed.
true? I believe due to how it starts with positive 4 and is subtracted by -8 this conceding a negative number.

The modal represent the division is 6 ÷ 6/9 = 9.
What is division?One of the most fundamental operations in arithmetic is division, in which a larger number is divided into smaller groups with the same number of items. Dividing a large group into smaller groups so that each group has the same number of items is called division. In math, it is an operation that equalizes sharing and grouping.
Given the number line in figure,
shows the number is divided in 9 equal parts
1/9, 2/9, 3/9, ..........9/9
and from 0 to 6/9 parts are marked,
there are 6 parts in 0 to 6/9
the division model for equation is
6 ÷ 6/9
and division is 6 ÷ 6/9 = 9
Hence the division sentence is represented by the model is 6 ÷ 6/9 = 9.

Solve to find X. 1/5(x - 2) = 1/10 (x + 6)
Answer:
x = 10
Step-by-step explanation:
First, distribute:
[tex]\frac{1}{5} x - \frac{2}{5} =\frac{1}{10} x+\frac{6}{10}[/tex]
Next, subtract [tex]\frac{1}{5}x[/tex] from both sides:
[tex]-\frac{2}{5} = \frac{1}{10} x -\frac{1}{5} x+\frac{6}{10}[/tex]
(multiply [tex]\frac{1}{5}x[/tex] by 2 to get common denominator, [tex]\frac{2}{10} x[/tex] )
[tex]-\frac{2}{5} =-\frac{1}{10}x +\frac{6}{10}[/tex]
Next, subtract [tex]\frac{6}{10}[/tex] from both sides:
[tex]-\frac{2}{5} -\frac{6}{10} =-\frac{1}{10} x[/tex]
(multiply [tex]\frac{2}{5}[/tex] by 2 to get common denominator, [tex]\frac{4}{10}[/tex] )
[tex]-\frac{10}{10} =-\frac{1}{10} x[/tex] ⇒ [tex]-1=-\frac{1}{10} x[/tex]
Next, multiply both sides by 10:

I'm having a bit of trouble finding out how to find the Domain of this function. Help please!
In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?
