Answer:
Probability = 9/25
This is 36%
Step-by-step explanation:
To find the probability take the total number of possibilities (25 marbles--all of them) put that number on the bottom of a fraction. Then put the number of ways that outcome can happen (9 blue and black) and put that on top of the fraction.
Probability(event)
= specific/total
Probability(blu&blk)
= 9/25
If the fraction can be simplified, do that. 9/25 cannot be simplified.
If you need a percent for your answer, divide then multiply by 100.
A fraction bar is a division symbol.
9/25 means 9÷25.
9/25 = .36
Percent means "per hundred" To convert a decimal to a percent, multiply by 100
.36×100 is 36%

eeeeeehelpmeeeeeeeeeee value of x and y
Step-by-step explanation:
As we can see x and 70° is alternate with each other so it can be name as alternative angle ....
Alternative angle are always equal....So .....
x = 70° ( being alternative angle )
Now....we can see that y and x is vertically opposite ....so it can be name as vertically opposite angle....
y = x ( being vertically opposite angle )
y = 70°

(9x - 17)
(4x + 28)
T
S
Simplifying
9x + -17 = 4x + 28
Reorder the terms:
-17 + 9x = 4x + 28
Reorder the terms:
-17 + 9x = 28 + 4x
Solving
-17 + 9x = 28 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-17 + 9x + -4x = 28 + 4x + -4x
Combine like terms: 9x + -4x = 5x
-17 + 5x = 28 + 4x + -4x
Combine like terms: 4x + -4x = 0
-17 + 5x = 28 + 0
-17 + 5x = 28
Add '17' to each side of the equation.
-17 + 17 + 5x = 28 + 17
Combine like terms: -17 + 17 = 0
0 + 5x = 28 + 17
5x = 28 + 17
Combine like terms: 28 + 17 = 45
5x = 45
Divide each side by '5'.
x = 9
Simplifying
x = 9

Answer:
x = 6
Step-by-step explanation:
To find x we set up an equation as so:
[tex]\frac{4.5}{x} =\frac{6}{8}[/tex]
Then we solve by multiplying 4.5 by 8 and 6 by x
[tex]6x=36[/tex] Solve for x
[tex]\frac{6x}{6} =\frac{36}{6}[/tex] x = 6
To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number
[tex]\frac{4.5}{6} =\frac{6}{8}[/tex] when divided both equals 0.75

Linda hiked 10 miles last weekend. She plans to hike 3/5 of that distance next weekend. enter the distance in miles that Linda plans to hike next weekend
Answer:
6 Miles
Step-by-step explanation:
What do we know: Linda hiked 10 miles last weekend, and she plans to walk 3/5ths of that next weekend.
Thus, we take 10 and multiply it by 3/5.
To understand it all better, let's write the equation like this, X will be the number of miles Linda plans to hike next weekend.
[tex]\frac{10}{1}[/tex]×[tex]\frac{3}{5}[/tex] = [tex]\frac{30}{5}[/tex]
Afterwards we can simplify like so, factoring 5 from both the numerator and the denominator:
[tex]\frac{5(6)}{5(1)}[/tex]
The 5's in the numerator and denominator cancel out, leaving us with:
[tex]\frac{6}{1}[/tex]
Or in simpler terms 6. Thus we can know that Linda will hike 6 miles next weekend.
What is the sum 2, 3, 4, and 5?
Answer:
14
Step-by-step explanation:
We can find the sum of these numbers by adding them together.
The cumulative rule of addition lets us add numbers together in any order we want.
So, for 2 + 3 + 4 + 5 …
2 + 3 = 5
So now we have 5 + 4 + 5
5 + 4 = 9
Now we have 9 + 5
And 9 + 5 = 14
So, your answer is 14

-2x^2 + 4x + 16 in vertex form
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form

A higher percentage of 8th graders than 7th graders prefer Math/Science.
The statement second a higher percentage of 7th graders than 8th graders prefer English and statement third a higher percentage of 8th graders than 7th graders prefer Math/Science are correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
We can find conditional relative frequency as:
For first cell:
= 38/116
= 0.327
= 32.75% (refer attached picture)
Similarly, we can find for other cells.
A higher percentage of 7th graders than 8th graders prefer English and History, while a higher percentage of 8th graders than 7th graders prefer Math/Science.
Thus, the statement second a higher percentage of 7th graders than 8th graders prefer English and statement third a higher percentage of 8th graders than 7th graders prefer Math/Science are correct.

the size of a triangle are X cm, (X-5)cm and (X+3)cm long. if the perimeter is 25 cm, find the length of the three sides?
Step-by-step explanation:
let's be more detailed than the other answer :
the perimeter is the sum of all sides of an object. in case of a triangle, well, that is the sum of all 3 sides.
so,
25 = x + (x-5) + (x+3) = x + x - 5 + x + 3 = 3x - 2
27 = 3x
x = 9
so, the sides are
x = 9 cm
(x-5) = 9 - 5 = 4 cm
(x+3) = 9 + 3 = 12 cm

Five friends are sharing 6 cups of lemonade. If they share the lemonade equally, how many cups
will each friend get?
Answer:
[tex]1\frac{1}{5}[/tex]
Step-by-step explanation:
6/5
= 1 1/5
Answer:
[tex]1\frac{1}{5}[/tex]
Step-by-step explanation:
First, we do 6 / 5 = 1.2. We do this because we are sharing 6 cups with 5 friends - we are dividing 6 cups between 5 friends.
So, each friend will get 1.2 cups. But, the question is asking for a fraction. 0.2 is the same as [tex]\frac{1}{5}[/tex], so each person will get [tex]1\frac{1}{5}[/tex]
Alternatively, you could do [tex]\frac{6}{5} = 1\frac{1}{5}[/tex]
Hope this makes sense.
