Answer: 147, 76 and 56.5
Step-by-step explanation:
11, and 12
Both of these questions require that you find the sum of both angles, and you know this because an angle written down starts with an outside point, a middle point then another outside point. So n, the left side, p the middle, and q, the outside. You add everything in between, the 78 and 68, and you get 147.
13
13 is different because a straight line is equal to 180 degrees, we know this because a full circle is 360 degrees and you split in in half with a straight line going through the center and you get 180 degrees on each side, so with this one you just take 180 - 23.5, and you get 56.5!
Its a i just know but it might be wrong
Answer:
Math has the particularity that it is a logical construction.
This means that we can start with an expression X (where X is an equation, not a variable)
Now we can apply a lot of "math" to this equation in such a way that we can rewrite it, but the actual "meaning" of the equation will not change.
An example of this is factoring.
For example, we can write a quadratic equation as:
a*x^2 + b*x + c.
And we also can write this as:
n*(x - k)*(x - j)
where k and j are the solutions of the equation:
a*x^2 + b*x + c = 0.
What is the advantage of writing the equation in each form?
Well, both expressions actually represent the same thing, but the explicit information in each expression is different, so depending on what we want to do, we will choose one option or the other.
And we have lot's of different ways to express something, where we can find some ones really complex and useful, like the series of Taylor, where we can write a function as a summation of infinite terms.
Here,
n = 11
mean = 7
Standard Deviation (σ) = 3
S.E. = ?
We know that,
S.E. = σ/
S.E. = 3/
∴ S.E. = 0.905 Ans.
The remainder is 8 in the given synthetic division problem. which is the correct answer would be option (B).
<h3>What is the division operation?</h3>
In mathematics, divides left-hand operands into right-hand operands in the division operation.
In the given synthetic division, the coefficients of terms are 4,6, and -2.
Fill in the first coefficient as it appears on the bottom line.
Now multiply 1 by 4 and write the result (i.e., 4) underneath the second coefficient in the center line.
Now multiply 6 by 4 and write the result (i.e., 10) in the bottom row.
Now multiply 1 by 10 and write the result (i.e., 10) below the third coefficient in the center line.
Now add -2 with 10 and write the result (i.e., 8) in the bottom row.
The first two terms now indicate the polynomial coefficient, while the last term shows the remainder.
Therefore, the remainder is 8 in the given synthetic division problem.
