Answer:
Independent
Dependent
Step-by-step explanation:
Two events are independent of each other when you can mulitply them and get their intersect
we can can see that
9/20*7/10= 63/200 so these events are independent
For number 2
7/10*7/10≠ 21/40 so these events are dependent

Please graph the linear equation y= 35x + 2
Answer:
Refer to attachment .
Step-by-step explanation:
We need to plot the graph of ,
[tex]:\implies[/tex] y = 35x + 2
Plot different values of x :-
[tex]:\implies[/tex] y = 35*1 + 2
[tex]:\implies[/tex] y = 35 + 2
[tex]:\implies[/tex] y = 37
[tex]\rule{200}2[/tex]
[tex]:\implies[/tex] y = 35*2 + 2
[tex]:\implies[/tex] y = 70 + 2
[tex]:\implies[/tex] y = 72
Hence now plot the points (1,37) and (2,72) .

If the area of trapezoid is 100 cm, what is the perimeter of the trapezoid?
Answer:
Step-by-step explanation:
If the area of trapezoid is 100 cm²what is the perimeter of the trapezoid?
Area of a trapezoid = 100cm
= 1/2(a + b) × h = 100cm²
Perimeter of a trapezoid = a + b + h
Solve the triangle.
a = ?
9514 1404 393
Answer:
a = 7
Step-by-step explanation:
The Pythagorean theorem tells you the value of 'a' is ...
a^2 = b^2 - c^2
a^2 = 25^2 -24^2 = 625 -576 = 49
a = √49 = 7
The length of side 'a' is 7 units.
7. Determine the area of the figure on the coordinate grid. Round to the nearest hundredth if needed. Show all work to receive credit. Bubble your answer on the griddable.
Answer:
72 square units.
Step-by-step explanation:
To find the area of the figure, we just need to find the area of the whole trapezoid and subtract the area of the small rectangle.
First, for a trapezoid of bases B₁ and B₂, and of height H, the area is:
A = (1/2)*(B₁ + B₂)*H
In the case of the image, the bottom base is 15 units long (each small square is a unit).
B₁ = 15 units
And the top base is 5 units long:
B₂ = 5 units
And the height is 10 units long.
H = 10 units.
Then the area of the trapezoid is:
A = (1/2)*(15 units + 5 units)*10 units = (1/2)*(20 units)*10 units
A = 100 square units.
The area of a rectangle of length L and width W is:
A' = W*L
In the graph we can see that:
L = 7 units
W = 4 units
A' = (7 units)*(4 units) = 28 square units.
Then the area of the figure is:
Area = A - A' = 100 square units - 28 square units = 72 square units.

what additional information is required to prove triangle ABC congruent to triangle DCB by hypotenuse-leg?
The correct option is 3.
Step-by-step explanation:
The HL theorem states that 'if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.'
From the given figure it is noticed that triangle ABC and triangle EDC. In triangle ABC and triangle EDC, hypotenuses of triangles are AB and DE respectively.
To use HL hypotenuse and one leg of triangles must be equal.
AB=DE (hypotenuse)
AC=DE (leg)
BC=ED (leg)
Therefore the additional information will allow you to prove the triangles congruent by the HL Theorem. Option 3 is correct.

Answer:
Equation: 3(x+5)=60
Solution: 15 inches
Step-by-step explanation:
Let x represent the original side length of the equilateral triangle. Then, the new length of each side is x+5. Because a triangle has three sides, the new perimeter is 3(x+5), which is 60 inches. Dividing both sides by 3, we get that x+5=20, so x=15.

Answer:
EFG = 104°
GFH = 76°
Step-by-step explanation:
The sum of a linear pair is always equal to 180°
So lets solve for the variable n
2n + 32 + 4n + 16 = 180
6n + 48 = 180
6n = 132
n = 22
So now we know N
EFG = 4n + 16
EFG = 88 + 16
EFG = 104°
GFH = 2n + 32°
GFH = 44 + 32
GFH = 76°

Step-by-step explanation:
How would you find the missing value? 15/4=5/x
15(4) = 5x
15(x) = 5(4)
15 14 =5+x
Using the intersecting chord theorem you multiply the two lengths of one line together to equal the multiplication of the two dimensions on the second line.
The answer would be 15(4) = 5x

Noah says, "If I try to write 100 expanded, it should have zero factors that are 10, so it must be equal to 0." Do you agree? Why or why not?
Answer:
Disagree
Step-by-step explanation:
10^0
According to the laws of indices, anything raised to the power of 0 will equate to 1. Therefore, based on this established mathematical principle, Noah's assertion about 10^0 being equal to 0 is false.
Hence, I disagree.

Answer:
a = [tex]\frac{1}{2}[/tex] , b = 5, and [tex]\frac{2b}{a}[/tex] = 20
Step-by-step explanation:
f(x) = - x² + b, x ≤ 0 You would use this equation for f(-2). Since -2 is less than 0.
f(x) = - x² + b, x ≤ 0 ← You can ignore the x ≤ 0 part.
f(-2) = - (-2)² + b Input the value -2 as x. The question states that f(-2) =1.
1 = - (-2)² + b So switch f(-2) with 1 on the left side only.
1 = - (4) + b Simplify. Do the exponents first, so (-2)² = 4.
1 = - 4 + b
+4 +4 Do inverse operations
5 = b
Next,
f(x) = 2ax +3, x > 0 You would use his equation for f(2). Since 2 is greater than 0.
f(x) = 2ax +3, x > 0 ← You can ignore the x > 0 part.
f(2) = 2a(2) + 3 Input the value 2 as x.
f(2) = 4a +3 Simplify. The equation states f(2) = 5. So switch f(2) with 5
5 = 4a +3 on the left side only.
-3 - 3 Do inverse operations
2 = 4a
[tex]\frac{2}{4}[/tex] = [tex]\frac{4a}{4}[/tex] Divide 4 on both sides to isolate the variable a
[tex]\frac{2}{4}[/tex] = a Simplify
[tex]\frac{1}{2}[/tex] = a
Then,
The second part says to find [tex]\frac{2b}{a}[/tex]
[tex]\frac{2b}{a}[/tex]
[tex]\frac{2(5)}{(\frac{1}{2}) }[/tex] Input both the values of a and b
[tex]\frac{10}{\frac{1}{2} }[/tex] Simplify
20.
The answer for a is [tex]\frac{1}{2}[/tex], the answer for b is 5, and the answer for [tex]\frac{2b}{a}[/tex] is 20.
7,10,3 how do I find the least common multiple
Answer:
Step-by-step explanation:
Usually you do it by factoring into primes. But this choice of numbers has no common primes, so all three make up the LCM
7 * 10 * 3
210 = LCM
LCM of 4 10 and 12
4: 2 * 2
10: 2 * 5
12: 2*2*3
LCM: 2 * 2 * 3 * 5 = 60
If you don't find the LCM then the answer would be 480
Answer:
210
Step-by-step explanation:
When finding the LCM(least common multiple) you need to factor each number into the product of prime number also called finding the prime factorization. Both 7 and 3 are prime, so they do not need to be factored further. However, 10 can be factored into 5 x 2.
3 - 3
7 - 7
10 - 5 x 2
By looking at the factors above, you notice none of them are the same, so none of the numbers share factors. This means you can just multiply all the factors to get the LCM:
3 x 7 x 5 x 2
210
Use r = 2 and r = 5 to determine if the two expressions are equivalent. r + 4(2 + r) – 12 8 + 2r – 6
Answer:
No they are not equivalent
Step-by-step explanation:
The given expressions are r + 4(2 + r) – 12, and 8 + 2r – 6
Let us first put r= 2 in the above expression
2+4(2+2)-12= 6
and 8+2(2)-6 = 6
Now let us put r=5 in the above two expressions
5+4(2+5)-12 = 21
similarly, 8+2(5)-6 = 12
Clearly, the two expressions are not equivalent when we put r=2 and r=5 as the values coming are different.
Answer:
the first expression is 6.
the second expression is 12.
they are NOT equivalent.
