P(S) = 5/8
P(T) = 1/8
If S and T are mutually exclusive events, find P(S or T),
Answer:
P(S ∪ T) = 3/4
Step-by-step explanation:
Given:
P(S) = 5/8P(T) = 1/8For mutually exclusive events S and T,
P(S ∪ T) = P(S) + P(T)
Therefore,
P(S ∪ T) = (5/8) + (1/8)
= 6/8
= 3/4

Draw the image of quadrilateral ABCD under a translation by 2 units to the left and 3 units up.
The image of the quadrilateral after the translation is added as an attachment
How to determine the image of the quadrilateral?The given parameter represents the quadrilateral ABCD on the graph.
On this graph, we have the coordinates of ABCD to be:
A = (2, -3)
B = (-1, 3)
C = (-1, -3)
D = (-4, -4)
The translation is given as
2 units to the left and 3 units up.
Mathematically, this can be represented as
(x, y) = (x - 2, y + 3)
So, we have
A' = (0, 0)
B = (-3, 6)
C = (-3, 0)
D = (-6, -1)
Next, we plot the above coordinates on the graph (See attachment)

Brad began working on a project at 10:15 A.M. He finished the work at 5:08 P.M.
How long did it take Brad to complete the project?
Answer:
It is a good idea to convert the times into internation time
thus, 5:08 becomes 17 08
Substraction:
17 08 - 10 15
= 16 68 - 10 15 ( I took one hour from 17 and added 60 minutes to 08)
= 6 53

Jerry is running a race. He knows he can run 44 feet in 3 seconds. If he maintains this rate, how many miles will he run in 1 hour?
Step-by-step explanation:
44 ft in 3 seconds
in 1 hour there are 60 minutes with 60 seconds each.
so, 1 hour = 60×60 = 3600 seconds.
in 3600 seconds there are
3600 / 3 = 1200 "packages" of 3 seconds.
so, Jerry would run
1200 × 44 = 52800 ft in 1 hour.
there are 5280 ft in 1 mile.
that means Jerry would run
52800 / 5280 = 10 miles in 1 hour.

Answer:
48pi cm squred
Step-by-step explanation:
first find area of the circle which is pi x r^2
pi x 3^2 = 9pi
Since there are two circles...
9pi x 2 = 18pi
Then find the area of the rectangle that is wrapped around the circle by finding the circumference of the circle and then multiplying that with the height of the cylinder
circumference of the circle = 2 x pi x r
2 x pi x 3 = 6pi
6pi x 5 = 30pi
Therefore the surface area is
48pi cm squred

Kiran bent some wire around a rectangle to make a picture frame. The rectangle is 8 inches by 10 inches. what is the perimater
Answer:
62.8 inches
.Step-by-step explanation:
The wire consists of 14 semicircle + 4 3/4 circles. The diameter of each circle = 8 / 4 = 2 inches.Length of a semicircle = 1/2 * pi * diameter and of a 3/4 circle it is 3/4 * pi * diameter.So the perimeter of the wire= 14 * 1/2 * 3.14 * 2 + 4 * 3/4 * 3.14 * 2= 14 * 3.14 + 4 * 3/2 * 3.14= 62.8 inches.
Answer:
62.8 inches
Step-by-step explanation:
= 14 * 1/2 * 3.14 * 2 + 4 * 3/4 * 3.14 * 2
= 14 * 3.14 + 4 * 3/2 * 3.14
= 62.8 inches.

If cos A = k, then the value of the expression (sin A)(cos A)(tan A) is equivalent to:
1). 1
2). 1/k
3). k
4). k²
Answer:
[tex](\sin A)(\cos A)(\tan A)=1-k^2[/tex]
Step-by-step explanation:
[tex]\textsf{Trig identity}: \quad \tan A=\dfrac{\sin A}{\cos A}[/tex]
[tex]\begin{aligned}\implies (\sin A)(\cos A)(\tan A)& =(\sin A)(\cos A)\dfrac{(\sin A)}{(\cos A)}\\\\& =\dfrac{(\sin A)(\cos A)(\sin A)}{(\cos A)}\\\\& =\sin^2 A\\\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Trig identity}: \quad \sin^2 A + \cos^2 A &=1\\\implies \sin^2 A & =1-\cos^2 A\end{aligned}[/tex]
[tex]\implies (\sin A)(\cos A)(\tan A)=1-\cos^2 A[/tex]
If [tex]\cos A=k[/tex] then:
[tex](\sin A)(\cos A)(\tan A)=1-k^2[/tex]
The value of the expression (sin A)(cos A)(tan A) is equivalent to[tex]1 - k^2[/tex], which corresponds to option 4). k².
How to determine the value of the expression (sin A)(cos A)(tan A) is equivalentLet's use the trigonometric identity: tan A = (sin A) / (cos A).
Given cos A = k, we can find sin A using the Pythagorean trigonometric identity:[tex]sin^2 A + cos^2 A = 1.[/tex]
[tex]sin^2 A + k^2 = 1[/tex]
[tex]sin^2 A = 1 - k^2[/tex]
sin A = √(1 - [tex]k^2[/tex])
Now, the expression (sin A)(cos A)(tan A) is:
(sin A)(cos A)(tan A) = (√(1 - [tex]k^2[/tex]))(k)((√(1 -[tex]k^2[/tex]))/k)
Now, we can cancel out the common terms:
(sin A)(cos A)(tan A) = (√(1 - [tex]k^2[/tex]))(√(1 - [tex]k^2[/tex]))
Taking the square root of the product:
(sin A)(cos A)(tan A) = √((1 -[tex]k^2[/tex])(1 - [tex]k^2[/tex]))
(sin A)(cos A)(tan A) = √((1 -[tex]k^2[/tex][tex])^2[/tex]
(sin A)(cos A)(tan A) = [tex]1 - k^2[/tex]
So, the value of the expression (sin A)(cos A)(tan A) is equivalent to [tex]1 - k^2[/tex], which corresponds to option 4). k².

What is the slope of the line?
Answer:
-3
Step-by-step explanation:
First, let's remind ourselves the definition of a slope.
Slope = rise/run OR the height from one point to another/ the distance from one point to another.
First, let's find two points on this graph that are marked easily.
One point that can be found is (0, -3) and the other is (0, -1).
Let's apply our formula to these points!
<------- Starting from point (0, -3), we are RISING 3 points and RUNNING -1 points.
Rise 3
------- = ----------
Run -1
3/-1 = -3
The slope of the line is -3.
Answer:
-3.
Step-by-step explanation:
1) to choose two points on the given line on the graph. For example, A(-2;3) and B(-1;0);
2) to calculate the required slope according to the rule:

What is the perimeter of the rectangle in the coordinate plane?
14 units
28 units
36 units
45 units
Answer:
45 units^2
Step-by-step explanation:
W x H = area
9 x 5 = 45 units^2
Answer:
28 units
Step-by-step explanation:
Length (l) = 9 units
Breadth (b) = 5 units
Perimeter of the rectangle will be,
→ 2(l + b)
→ 2(9 + 5)
→ 2 × 14
→ 28 units
Hence, the perimeter is 28 units.

Can you turn all the mixed numbers in the boxes into and improper fraction please!!!
Answer:
answers are in the attached file!
Step-by-step explanation:
these are super simple to solve if you break it down! in order to turn a mixed number into an improper fraction, you first need to multiply the whole number by the denominator of the fraction. then, you add the numerator of the fraction to the product of the multiplication problem. that answer is then the new numerator of the fraction! the denominator will stay the same.
for example, the very first one that is given in the picture is 6 1/2. 6•2 equals 12, plus the numerator, 1, gives 13.

Answer:
The new points to the triangle will be:
[tex]A(-6, 6)\\B(-6, 3)\\C(-8, 3)[/tex]
Step-by-step explanation:
Because the reflection point is at [tex]x = -1[/tex], all x values will subtract their distances from [tex]x = -1[/tex] to get their new values. The y values remain the same.
The starting values are:
[tex]A(4,6)\\B(4,3)\\C(6,3)[/tex]
Point [tex]A[/tex] is 5 units away from [tex]x = -1[/tex], so we'll subtract 5 from -1 to get the new x value: [tex]-1 - 5 = -6[/tex], so [tex]A(-6, 6)[/tex].
Point [tex]B[/tex] is also 5 unit away from [tex]x = -1[/tex], so we'll subtract 5 from -1 to get the new x value: [tex]-1 - 5 = -6[/tex], so [tex]B(-6, 3)[/tex].
Point [tex]C[/tex] is 7 units away from [tex]x = -1[/tex], so we'll subtract 7 from -1 to get the new x value: [tex]-1 - 7 = -8[/tex], so [tex]C(-8, 3)[/tex].

What is the combined length of all the buttons longer than 1 inch?
The sum of 6 and the product of 3 and d
Answer:
6 + 3d
Step-by-step explanation:
First, we can translate from English words to mathematical operations:
– Product: the result of multiplication
– Sum: the result of addition
So, we can rephrase the original sentence as “the result of adding 6 and (the result of multiplying 3 and d)”
When we multiply a constant like 3 by a variable like d, we usually write the two next to each other, which would be “3d” in this case. We can replace that last sentence in symbols with 6 + 3d
