Determine whether the events are mutually exclusive or not mutually exclusive. Then find the probability. Round to the nearest tenth of a percent, if necessary.rolling a pair of dice and getting a sum of either 6 or 10
According to the question, to check whether the events are mutually exclusive or not mutually exclusive for the rolling pair of dice to get the total either as six or ten.
What are mutually exclusive events?
Mutually exclusive events are those events which cannot happen at the same time .For instance, in any event nobody can run forward or backward together at the same time.
Rolling a pair of dice to get the sum as 6, then is not mutually exclusive.
The calculation is as shown below:
P(E) = 6+5-1/36
= 10/36
= 5/18
= 27.8 %
Now, rolling a pair of dice to get either the sum as 6 or 10.
P(6 or 10)
= P(6)+P(10)
= 5/36+ 3/36
= 8/36
= 2/9
= 22%
Hence, it is not mutually exclusive event because the calculated percentage is 22%.

What is a right angled triangle ?
A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees.
As per the question ;
The triangle is a right angle triangle, so it's two sides can be located
on axis.
Place the right angle of the triangle Δ MNO at M.
i.e., M will have coordinates (0,0)
The origin will allow the two legs to be along the x and y-axes , so position the triangle in the first quadrant.
As N is on the y-axis ;
Its x-coordinate will be 0 and the y-coordinate will be a , because the leg is a units long.
i.e., N will have coordinates (0,a)
As O is on the x-axis,
its y-coordinate will be 0 and the x-coordinate will be 2a , because the leg is 2a units long.
i.e.,
O will have coordinate (2a,0)
We can put these coordinates after placing the triangle in the first quadrant i.e., M (0,0) , N (0,a) & O (2a,0).
Thus , we need to position the right triangle Δ MNO in the first quadrant with coordinates , M(0,0) , N (0,a) & O (2a,0).

The measure of ∠B rounded to the nearest whole number is 71°
TrigonometryFrom the question, we are to calculate the measure of ∠B.
In the given diagram, we have a right triangle.
In the right triangle,
The hypotenuse is 21
Adjacent is 7
From SOH CAH TOA,
We have that
sin θ = Opposite / Hypotenuse
cos θ = Adjacent / Hypotenuse
tan θ = Opposite / Adjacent
Thus,
we can write that
cos B = 7/21
cos B = 1/3
B = cos⁻¹(1/3)
B = 70.528
B ≈ 71°

The sum is a trinomial with a degree of 2.
The sum is a trinomial with a degree of 3.
The true about the sum of the two polynomials- 6s^2t – 2st^2 and 4s^2t – 3st^2 is The sum is a binomial with a degree of 3.
What are polynomials?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Now the given polynomials are,
6s^2t – 2st^2 and 4s^2t – 3st^2
Now adding these two polynomials we get,
Sum of polynomials = 6s^2t – 2st^2 + 4s^2t – 3st^2
Taking alike terms together,
= 6s^2t + 4s^2t – 2st^2 – 3st^2
Now simplifying we get,
= 10s^2t – 5st^2
Here we see that the highest power of a variable is 2.
Thus this sum of polynomials is a binomial.
Now sum of the powers of variable s and t = 2 + 1 = 3
Thus, Degree of the sum of polynomials is 3.

Evaluate -(8/-4) ^2 + 2 - 4^3
Answer:
-(8/-4)² + 2 - 4³ = -66
Step-by-step explanation:
-(8/-4)² + 2 - 4³
Here we need to respect the order of operations.
So ,first we calculate what’s between parentheses :
8/-4 = -2
Then
-(8/-4)² + 2 - 4³ = -(-2)² + 2 - 4³
Then
We calculate the exponent :
(-2)² = (-2) × (-2) = 4
4³ = 4 × 4 × 4 = 64
Then
-(8/-4)² + 2 - 4³ = -4 + 2 - 64
Then
The expression -4 + 2 - 64 contains addition and subtraction.
So ,we start calculating from left to right :
-4 + 2 = -2
Then
-4 + 2 - 64 = -2 - 64 = -66
Conclusion :
-(8/-4)² + 2 - 4³ = -66

remember, the domain is the interval or set of all valid x values, the range is the interval or set of all valid y values (functional result values).
1.
domain : -infinity < x < +infinity
range : -1 <= y < +infinity
due to the x² term that part can never be negative. the minimum is 0, and then -1 gives us a overall minimum -1. and then up ... the sky is the limit ...

the only forbidden value of x is therefore
3x + 5 = 0
3x = -5
x = -5/3
so, (-infinity < x < -5/3) OR (-5/3 < x < +infinity)

a) 45
b) 3
c) 4
d) 7
The correct option is d) 7.
A production function indicates the proportion of a combination of inputs (labor and capital) that produces a given amount of output. Firms determine the quantity produced given the output price level and the quantity of a combination of input factors provided by the prices of capital and labor. Dividing the output by the number of capital and labor units employed gives the average capital and labor production, respectively.
The production functions,
Q = 3 K + 4 L
k = 10
L = 10
Q = 3 ( 10 ) + 4 ( 10 )
Q = 30 + 40
Q = 70
Average capital production is calculated by dividing output (Q) by the amount of capital used to produce that output (K).
Average capital production = output / capital
= 70 / 10

Then she tries to line them up in rows of seven, but there are four band members in the last row. Finally, she tries to line them up in rows of eight, but there are five band members in the last row.
The band has fewer than $200$ members.
How many members are there?
Based on the given task content, the number of members in the marching band if the band has fewer than 200 members is 195 members
How to find the number of members in the group?When the band members are told to line up in rows of eight but five is left over. This means the overall number is an odd number.
When they are lined up in rows of six, but three are left over. So, eliminate numbers with 3, 5, 6 ,9, 0.
Finally they are lined up in rows of seven, but four are left over.
So, eliminate numbers with 7 also.
So, all eliminated numbers are : 2,3,4,5,6,7,8,9,10
Left numbers are 1.
Given is that the band has fewer than 100 members. So, it can be 71 ,81 ,91

The formula of perimeter: √(x₂−x₁)²+(y₂−y₁)²
Filling the values in the formula, we obtain:
= √(7−16)²+(6−14)²= 70.37 unitsThen, each side of the triangle will be: 70.37 units
Therefore, ΔJKL has sides that are 70.37 units.

Which value of p is a solution to this equation?
p–6=2
Answer:
[tex] \sf \large \: p = 8[/tex]
Step-by-step explanation:
Let's solve the equation step by step,
p – 6 = 2
Add +6 to both sides
p - 6 + 6 = + 6
p = 8
Answer:
8
