Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given: In basket, we have
4 black socks, 7 pink socks, and 10 white socks.
Total socks = 4+7+10 = 21
Probability that first sock is pink = [tex]\dfrac{\text{Number of pinks socks}}{\text{Total}}=\dfrac{7}{21}=\dfrac13[/tex]
Now basket has 6 pink socks left and total socks left= 20
Probability that second sock is pink =[tex]\dfrac{6}{20}=\dfrac{3}{10}[/tex]
The probability that Allison will select 2 pink socks = [tex]\dfrac13\times\dfrac{3}{10}=\dfrac{1}{10}[/tex]
Hence, the probability that Allison will select 2 pink socks = [tex]\dfrac{1}{10}[/tex]

The endpoints of a line segment AR are A(8,-2) and R(-4,1). What is the length of the AR?
Answer:
The length of the AR is [tex]3\sqrt{17}[/tex] or [tex]12.4[/tex] units.
Step-by-step explanation:
Given the endpoints of a line segment AR
A(8, -2)R(-4, 1)We can calculate the length of AR using the formula
[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
In our case,
(x₁, y₁) = (8, -2) (x₂, y₂) = (-4, 1)Substituting (x₁, y₁) = (8, -2) and (x₂, y₂) = (-4, 1) in the formula
[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(1-\left(-2\right)\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(1+2\right)^2}[/tex] ∵ Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]=\sqrt{12^2+3^2}[/tex]
[tex]=\sqrt{144+9}[/tex]
[tex]=\sqrt{153}[/tex]
[tex]=\sqrt{9\times 17}[/tex]
[tex]=\sqrt{17}\sqrt{3^2}[/tex] Apply radical rule: [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}[/tex]
[tex]=3\sqrt{17}[/tex] Apply radical rule: [tex]\sqrt[n]{a^n}=a[/tex]
[tex]=12.4[/tex]
Therefore, the length of the AR is [tex]3\sqrt{17}[/tex] or [tex]12.4[/tex] units.
what is the value of x?
enter your answer in the box
Answer:
39
Step-by-step explanation:
If i'm right, a triangle should add up to 180, so you add 39 and 102 to get 141. Then you subtract 141 from 180 and get 39
Answer:
39
Step-by-step explanation:
Remark
Every triangle has 180 degrees. The three angles must add to 180
Solution
x + 102 + 39 = 180
x + 141 = 180 Subtract 141 from both sides.
x + 141-141 = 180-141
x = 39

2) g(x) = 4x + 1 Find (gºg)(x)
Answer:
Step-by-step explanation:
g circle g (x) has the meaning of putting g(x) on the right wherever you see an x in the original question
gcircle g (x) = 4(g(x)) + 1
g circle g(x) = 4(4x + 1) + 1
g circle g(x) = 16x + 4 + 1
g circle g(x) = 16x+5
Find the percent of change from the first value to the second. 72: 81 -
is means "From 72 to 81"*
Answer:
+12.5%
Step-by-step explanation:
This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.
(81 - 72)/72 * 100
Subtract 72 from 81 to get 9
9/72 * 100
Multiply 9 by 100 to get 900
900/72
Simplify the above fraction by cancelling out 9.
100/8
Divide 100 by 8 to get 12.5%
The percent of change is +12.5%

The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour. Determine in how many hours the temperature will be 36 degrees Fahrenheit.
The answer is that it would take 8 hours for the temperature to drop down to 36 degrees.
1.5x8=12
1x8=8 and 0.5x8=4
In 8 hours the temperature will be 36°F from 48°F.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour.
Assuming the no. of hours to be x.
∴ 36 = 48 - 1.5x.
- 1.5x = - 12.
x = 8.
