A sock drawer contains winter socks and summer socks. Both varieties come in two colors: white and black. There is a pair of each combination. If a sock is selected randomly, what is the probability it will be a black sock or a summer sock? A. 0.25 B. 0.5 C. 0.625 D. 0.75
Answer:
D 0.75
Step-by-step explanation:
There are a total of 4 pairs: White-Summer, Black-Summer, White-Winter, and Black-Winter. There are a total of 8 socks.
The probability of pulling a black sock or a summer sock is the number of all black or summer socks divided by the total number of socks.
The number of black or summer socks includes 1 pair of White-Summer, 1 pair of Black-Summer, and 1 pair of Black-Winter.
This makes for 6 black or summer socks.
Divide 6 by 8 to get 0.75

How would I get the slope of this triangle?
Answer:
-4/3
Step-by-step explanation:
if the triangle is anchored at (0, 0) you come down
from point ( 0, 48) to point ( 36, 0) so the slope is
y= rise/run = -48/ 36 = -4/3

Step-by-step explanation:
the volume in a tank varies periodically. At t=0 is at its maximum of 520 gallomns and at t=6 it is at its miximum of 170 gallons. A function in the form y=Acos(Bx)+C can be used to model this situation.Based on the information given determine the values of A,B and C
Answer:
A = 175, B = π/6, C = 345
Step-by-step explanation:
The given variation of the volume in the tank and time includes are;
At t = 0 the volume in the tank, y = Maximum volume, [tex]y_{max}[/tex] = 520 gallons
At t = 6 the volume in the tank, y = Minimum volume, [tex]y_{min}[/tex] = 170 gallons
The function that models the situation is y = A·cos(B·x) + C
Given that the function that models the situation is the cosine function, we have;
A = The amplitude = (The maximum - The minimum)/2
∴ A = (520 - 170)/2 = 175
A = 175
The period = The time to change from maximum to minimum = 2 × The time to change from maximum (t = 0) to minimum (t = 6)
∴ The period = 2 × (6 - 0) = 12
The period = 12 seconds = 2·π/B
∴ B = 2·π/12 = π/6
B = π/6
C = The vertical shift = Th minimum + A = (The maximum + The minimum)/2
∴ C = (520 + 170)/2 = 345
C = 345

Answer:
2
Step-by-step explanation:
28 per hour
56 per ? hours
Use the equation:
56 = 28 h
Divide 56 by 28
56 / 28 = 28 h /28
56/28 = 2
2 = h

Answer:
See attachment >_<
Step-by-step explanation:
Because the line includes the point [tex](0,3)[/tex], we'll begin our line at this coordinate.
The slope is [tex]7[/tex], or, [tex]\frac{7}{1}[/tex]. Slope is formatted in the [tex]rise[/tex] in the line over its [tex]run[/tex]. Or, [tex]\frac{rise}{run}[/tex]. This means the line rises [tex]7[/tex] units and runs [tex]1[/tex] unit.
From our beginning point, [tex](0,3)[/tex], move up seven units and then to the right one unit.
If this line was negative (it would have a negative slope), we would run to the left. However, we have a positive slope, so we will run to the right.
By doing this, we land on the point [tex](1,10)[/tex]. Draw a line through this point with our beginning coordinate [tex](0,3)[/tex]. This is our graphed line. I've attached a photo as well :)

PLEASE ANSWER I WILL GIVE A BRAINLIEST
Answer:
a=2
b=2
Step-by-step explanation:
This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Write the equations in slope-intercept form: 15x + 3y = 6
(Help)
Answer:
y=-5x+2
Step-by-step explanation:
Before we get started, we should identify slope-intercept form.
y=mx+b.
Step 1 : Isolate the y by dividing everything by 3.
(15x+3y=6)/3 = 5x+y=2
Step 2 : Move the x value to the right side.
y=-5x+2
Answer:
y=5x-2
Step-by-step explanation:
15x+3y=6
3y=15x-6....both side divide by 3
y=5x-2
According to the diagram below, which similarity statements are true?
Check all that apply.

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In a right-angle triangle, the measure of one angle will be 90 degrees.
If any two angle of the triangles are congruent, then the triangles will be a similar triangle.
In triangle ΔABC and ΔADB, we have
∠A = ∠A (common angle)
∠B = ∠D = 90° (right angle)
Then the triangle ΔABC and ΔADB are similar triangles.
In triangle ΔABC and ΔBDC, we have
∠C = ∠C (common angle)
∠B = ∠D = 90° (right angle)
Then the triangle ΔABC and ΔBDC are similar triangles.
Then the correct options are B and C.

Answer:
y= -5/2x + 3/2
Step-by-step explanation:
(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.
(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.
Plugging in the two points, hence y= -5/2x + 3/2
