Explanation:
I'll represent the dice results as an ordered pair. Something like (6,2) means the first die is a 6 and the second is a 2. The sum being 6+2 = 8.
There are only two ways to get to a sum of 8, and those two ways are:
(6,2)(2,6)Here are other possibilities if we allow the sum to be larger than 8
(6,3)(6,4)(6,5)(6,6)(3,6)(4,6)(5,6)(6,6)You should find that there are a total of 10 ways to have two dice add to a value that is 8 or larger, given that at least one of the dice must be a 6.
This is out of 6*6 = 36 ways to roll two dice without such a restriction. The probability we're after is 10/36 = (2*5)/(2*18) = 5/18
Side note: 5/18 = 0.2778 = 27.78% approximately
The first term of an arithmetic sequence is 10 and its
common difference is -3. What is the sum of the first
10 terms of this sequence?
Please hurry! ill give brainliest
Answer:
The sum of the first ten terms is -35.
Step-by-step explanation:
The first term of an arithmetic sequence is 10, and its common difference is -3.
We want to find the sum of the first 10 terms of this sequence.
Remember that the sum for an arithmetic sequence is given by:
[tex]\displaystyle S=\frac{k}{2}\left(a+x_k\right)[/tex]
Where k is the number of terms, a is the initial/first term, and x_k is the last term.
Since our initial term is 10, a = 10.
And since we want to find the sum of the first ten terms, k = 10.
So, we will need to find the last or tenth term. We can write an explicit formula. The standard explicit formula for an arithmetic sequence is:
[tex]x_n=a+d(n-1)[/tex]
Where a is the initial term and d is the common difference.
So, by substituting, we acquire:
[tex]x_n=10-3(n-1)[/tex]
Then the tenth or last term is:
[tex]x_{10}=10-3(10-1)=10-3(9)=10-27= -17[/tex]
Then the sum of the first ten terms will be:
[tex]\displaystyle S_{10}=\frac{10}{2}(10+(-17))=5(-7)=-35[/tex]
Answer:
-35
Step-by-step explanation:
[tex]a_{1}[/tex] = 10+(-3)(0) = 10
[tex]a_{10}[/tex] = 10+(-3)(9) = -17
[tex]S_{10}[/tex] = 10[(10 -17)/2] = 10(-7/2) = -70/2

Answer:
A
Step-by-step explanation:
(0.5a, 0.5a) is the midpoint of the line BD and a is the value that belongs in the green box.
What is a midpoint?The midpoint of a line segment is a point that lies exactly halfway between two points.
Consider the points B(0,a) and D(a,0).
The general form of midpoint formula is given by
Midpoint = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)
Here, x₁ = 0, x₂=a and y₁ = a, y₂ = 0
Therefore, the value that belongs in the green box is given by
(x₁ + x₂)/2 = (0+a)/2 = a/2 = 0.5a
(y₁ + y₂)/2 = (a+0)/2 = a/2 = 0.5a
The midpoint is given by
Midpoint = ( (x₁ + x₂)/2 , (y₁ + y₂)/2) = (0.5a, 0.5a)
Hence, the value that belongs in the green box is a and the midpoint of the line BD is (0.5a, 0.5a).

Find the indicated side of the

45°
х
y = [?]
Answer:
y = 9√2
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
y² = 9² + x²
By the property of isosceles triangle,
Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.
Therefore, x = 9
y² = 9² + 9²
y² = 81 + 81
y² = 162
y = √162
y = 9√2

A pair of shoes that normally sells for $85.00 goes on sale for 35% off. Season thinks that the sale price should be $50.00 but Melanie disagrees and says the price should be $55.25. Aiyanna says they are both wrong and decides the price should be $29.75. Who is correct and why?
Answer:
Melanie is correct
Step-by-step explanation:
35% of 85 is 29.75 so take that away from the original price and you get 55.25
This means the price will be 55.25$
Answer:
Melanie is correct since 65% of $85.00 is $55.25.
Step-by-step explanation:
The original price of the shoes is $85.00. That is 100% of the price of the shoes since 100% is a whole amount.
The discount on the shoes is 35%.
100% - 35% = 65%
That means the sale price is 65% of the original price. Now we calculate 65% of $85.00.
65% of $85.00 =
= 0.65 * $85.00
= $55.25
Answer: Melanie is correct since 65% of $85.00 is 55.25.

Answer:
$420
Step-by-step explanation:
In the figure, the living room is 5 cm by 3.5 cm.
We use the scale to convert to the real measurements.
1 cm = 4 ft
5 cm * 4 ft/cm = 20 ft
3.5 cm * 4 ft/cm = 14 ft
The actual dimensions of the room are 20 ft by 14 ft.
actual area = 20 ft * 14 ft = 280 ft²
carpet cost = $1.50/ft²
cost of carpet = 280 ft² * $1.50/ft²
cost of carpet = $420

Terrell got 1 3/4 pounds of ground meat and 2 1/6 of ground chicken. he used 1 2/3 pounds of ground chicken to make a casserole. how much ground chicken did he have left?
Answer:
Okay so we have to solve this in separate parts. Like so, its wiill go like this: 2+ 1/6 - 1 - 2/3. So we see that we have 2 and 1 as whole. Subtract 2 - 1 is 1 right. Now for fractional part 1/6 - 2/3. Since its uneven, we have to find the LCD which is 6. This forms of our fractions into 1/6- 4/6. 1/6 - 4/6 is 3/6. simplify it would result in 1/2. The amount of ground chicken that Terrell has left is 1/2.

Which statement best describes whether the function is linear or nonlinear?
Answer:
Is nonlinear because the common ratio is 3
Step-by-step explanation:
A linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If this line passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Now to this problem, if the data corresponds to a linear equation, then for any set of points we choose we should see the same slope.
For example, if we choose the first and second points:
(0,20) and (1, 60) the slope is:
a = (60 - 20)/(1 - 0) = 40/1 = 40
a = 40
Now if we choose the first and third points:
(0, 20) and (2, 180)
The slope is:
a = (180 - 20)/(2 - 0) = (160/2) = 80
So the slopes are different, which means that this function is nonlinear.
If we look at the f(x) values for the second point onwards, we can see that:
f(2) = 60
f(3) = 60*3 = 180
f(4) = 180*3 = 540
f(5) = 540*3 = 1620
and so on.
So this seems to be an exponential function with a common ratio of 3 between consecutive outputs.
Having a common ratio is not a property of linear functions, then the correct options is:
"Is nonlinear because the common ratio is 3"
