Given:
M(-1,-4) is the mid point of points a(-3, -7)
and B
To find:
Coordinates of B
Explanation:
Let (x, y) be the coordinates of B.
Since M is the midpoint of A and B,
M-A IB-EM
YM-YA-YB-YM
Substituting the values,
The x coordinate will be
-1-(-3)=-(-1)
-1+3=x+1
=2-1 x = 1
The y coordinate will beYM YAYB-YM
Substituting the values,
The x coordinate will be
- 1 - (- 3) = x - (- 1) - 1 + 3 = x + 1 x = 2 - 1 x = 1
The y coordinate will be
- 4 - (- 7) = y - (- 4) - 4 + 7 = y + 4 y = - 1
y = 7 - 8
Hence x=1, y = - 1
Final answer:
The coordinates of B are (1,-1)
13. Simplify the expression.
-(10)-2
The expression will be 0.01
Simplifying an expression is just another way to say solving a math problem. When you simplify an expression, you're basically trying to write it in the simplest way possible. At the end, there shouldn't be any more adding, subtracting, multiplying, or dividing left to do
Rewrite the expression using the negative exponent rule b
b₋ⁿ= 1/b-ⁿ

The probability that the interval estimation procedure will generate an interval that contains the actual value of the population parameter being estimated is the _____.
The population parameter being estimated is the confidence coefficient.
What is a confidence coefficient?The confidence coefficient is the confidence level stated as a proportion, rather than as a percentage. For example, if you had a confidence level of 99%, the confidence coefficient would be . 99. In general, the higher the coefficient, the more certain you are that your results are accurate.
probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Hence, The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the confidence coefficient.

(4)(4) -4(-5)(-1) who ever knows this thank you<3
The answer of [tex](4)(4) -4(-5)(-1)[/tex] is [tex]-4[/tex]
We are supposed to find the answer of [tex](4)(4) -4(-5)(-1)[/tex].
This question is a classic example of the BODMAS rule in mathematics.
According to this rule, first we solve the sum inside bracket (be it any operation like division, multiplication, addition or subtraction) then division operation if present in the question followed by multiplication then addition and followed by subtraction.
Here in the question given [tex](4)(4) -4(-5)(-1)[/tex], we use BODMAS to solve it.
Let x be the answer of the above question, Therefore
[tex]x=(4)(4) -4(-5)(-1) \\x=(4*4)-4(5)\\x=(16)-(20)\\x=(16-20)\\x=-4[/tex]
Therefore[tex](4)(4) -4(-5)(-1)[/tex] = -[tex]4[/tex]
BODMAS: The BODMAS rule follows the order of the BODMAS abbreviated for B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – Subtraction. The BODMAS rule states that mathematical expressions with more than one operators need to be solved from left to right in the order of BODMAS.Want to learn more about BODMAS?

Find the 9th term of the arithmetic sequence 4x+44x+4, 9x+119x+11, 14x+18, 14x+18,...
Answer:
T9=60
Step-by-step explanation:
step 1: solve for x
it is an arithmetic pattern,so the 1st difference is the common difference (d)
therefore...9x+199x+11-(4x+44x+4)=14x+18-(9x+199x+11)
128x+11-48x-4=14x+18-128x-11
80x+7=-144x+7
80x+144x=7-7
224x=0
224x/224=0/224
X=0
step 2: substitute for x
4(0)+44(0)+4=4[1st term]
9(0)+119(0)+11=11(2nd term)
14(0)+18=18(3rd term)
step 3:find the common difference
d=3rd term- 2nd term, 2nd term-1st term
3rd term-2nd term
18-11=7
2nd term-1st term
11-4=7
therefore...d=7
step 4:find the general formula
we use the formula Tn=a+(n-1)d to find the general formula/ nth term
where: Tn is the nth term
a is the first term
n is the number of term
d is the common difference
Tn=a+(n-1)d
=4+(n-1)7
=4+7n-7
=7n-3
step 5:find the 9th term
Tn=a+(n-1)d
=7n-3
=7(9)-3

Given data:
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
The given equation is:
R = x + 9x
First, let's combine the like terms on the right side of the equation:
R = 1x + 9x
R = 10x
Now, we want to solve for x. To isolate x, divide both sides of the equation by 10:
R/10 = x
So, the solution for x is:
x = R/10

Part(A) Leslie's initial investment was $500 and
Part(B) The quarterly interest rate is 10.4 %
What is compound interest?
Compound interest is the interest calculated on the principal amount , which also considers all the accumulated interest of previous periods of deposit or loan.
If P is the principal amount and rate of compound interest is r then after t years of time , the present amount (if the interest is compounded annually) will be = P(1+(r/100))^n
If the interest is compounded quarterly, then the present amount be A
Where A = [tex]P (1+\frac{r/4}{100} )^{4t}[/tex]
Given that Leslie invests in a bank that earns interest quarterly , and account balance after t years is given as 500(1.026)^(4t)
A= [tex]P (1+\frac{r/4}{100} )^{4t} = 500(1.026)^{4t\\[/tex]
Comparing both sides we get P = 500
And 1+(r/400)=1.026
(r/400)=1.026-1
(r/400)=.026
r=400(0.26) = 10.4 %
Therefore , Leslie's initial investment was $500 and the quarterly interest rate is 10.4 %

The percentage of organ donors who died from drug overdoses changed by 9.34% - 1.10% =8.24% between 2000 and 2015. what is this as a percentage of donors dying from drug overdoses in 2000?
The current percentage in comparison to in the year 2000 is 88.22%.
We are given the percentage of death in the year 2000, 2015 and the difference. Now, we have to find the percentage of donors between change and the original deaths in the year 2000.
To find this, we will use the following formula -
Percentage change = Difference between the percentage change in the year 2000 to 2015 ÷ Percentage of deaths in the year 2000 ×100
Now, keep the values in formula to find the percentage change.
Percentage change = [tex]\frac{8.24}{9.34} *100[/tex]
Performing division to find the percentage change
Percentage change = 0.882*100
Further performing multiplication to get the answer in the form of percentage
Percentage change = 88.22%
Hence, the comparison of difference with the percentage of donors dying from drug overdoses in 2000 is 88.22%.
