1. Find the probability of rolling a sum less than 4 or a
sum greater than 8 when a pair of dice is rolled.
Answers
=============================================================
Explanation:
Refer to the chart below. The values in red up top add to the values in blue along the left column to get the 6 by 6 grid of values inside. This represents all of the possible ways to add up values on a pair of dice. There are 6*6 = 36 outcomes.
Of those 36 outcomes, we have 13 outcomes where we roll less than a 4, or greater than 8
outcome = 1+1 = 2outcome = 1+2 = 3outcome = 2+1 = 3outcome = 3+6 = 9outcome = 4+5 = 9outcome = 5+4 = 9outcome = 6+3 = 9outcome = 4+6 = 10outcome = 5+5 = 10outcome = 6+4 = 10outcome = 5+6 = 11outcome = 6+5 = 11outcome = 6+6 = 12These 13 results are shown in green boxes in the diagram.
Since we have 13 ways to get what we want, out of 36 total, the final answer as a fraction is therefore 13/36
13/36 = 0.3611 = 36.11% approximately

Find the distance from point A(2,-1) to the line y=-x+4
Answers
9514 1404 393
Answer:
(3/2)√2 ≈ 2.1213 units
Step-by-step explanation:
The distance d from point (x, y) to line ax+by+c = 0 is given by ...
d = |ax +by +c|/√(a^2 +b^2)
We can write the equation of the line as ...
x + y -4 = 0
so the distance is ...
d = |x + y - 4|/√(1^2 +1^2)
For point (x, y) = (2, -1), the distance is ...
d = |2 +(-1) -4|/√2 = 3/√2 = (3√2)/2
The distance from A(2, -1) to the line y = -x +4 is (3√2)/2 units.

I need help please I dont get this
Answers
Answer:
Step-by-step explanation:
Since this is a 30-60-90 triangle, we need the Pythagorean triple for such a triangle. the side length across from the 30 degree angle is labeled as x, the side across from the 60 degree angle is x√3, and the hypotenuse is 2x. Since we know the side length of the side across from the 60 degree angle, we use that identity and solve for x:
[tex]x\sqrt{3}=18[/tex] and
[tex]x=\frac{18}{\sqrt{3} }[/tex] and rationalizing the denominator,
[tex]x=\frac{18}{\sqrt{3} }*\frac{\sqrt{3} }{\sqrt{3} }=\frac{18\sqrt{3} }{3}=6\sqrt{3}[/tex]
This is the side length of the side across from the 30 degree angle. In order to find the hypotenuse, we have to multiply this value by 2 to get
12√3, the third choice down.

O {xx>-4 and x <2}
O {x| X <-4 or x > 2)
O {x} x <-2 or x > 4)
O {X/ x>-2 or x <4}
Answers
Answer:
{x | x < 2 and x < -4 }
Step-by-step explanation:
Given the inequality 5(x - 2)(x + 4) > 0?
This also means x - 2 < 0 and x + 4<0
For x - 2 < 0
Add 2 to both sides
x - 2 + 2 < 0 + 2
x < 2
Similarlry for x + 4 <0
Subtract 4 from both sides
x+4-4 < 0 -4
x < 0 -4
x < -4
x < 2 and x < -4
Hence the required solution is {x | x < 2 and x < -4 }

Answer:
x = 40
Step-by-step explanation:
Both angles are opposites and will therefore have the same measurements.
Set your formula up as
142 = 3x + 22
142 - 22 = 3x
120 = 3x
120/3 = x
40 = x
You can also test this by placing 40 in place of x in your formula to check your work
3 * 40 + 22 = 142

Calculate the normal selling price of a pair of shoes which was sold for Rs 1350 in the sale.
Answers
let be the real price x :
x - x × ( 25/100 ) = 1350
x - x × ( 1/4 ) = 1350
x - x/4 = 1350
4x - x / 4 = 1350
3x / 4 = 1350
3x = 1350 × 4
3x = 5400
x = 5400 ÷ 3
x = Rs 1800

Jenna is opening a clothing store. She plans to start by selling T-shirts. If it
costs her $7 for each shirt, $2 for ink per shirt, and $0.10 a bag, what is her
unit cost per shirt?
O A. $9.10
O B. $2.10
O c. $4.55
O D. $7.00
Answers
Her unit cost per shirt is,
= $9.10
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
Jenna's unit cost per shirt is, $9.10
Here, We have;
Cost for each shirt = $7
Cost for ink per shirt = $2
Cost of a bag = $0.10
Hence, Cost of T-shirt is,
= Cost for each shirt + Cost for ink per shirt + Cost for bag
= $7 + $2 + $0.10
= $9.10
Thus, Her unit cost per shirt is,
= $9.10
