Answer:
The 97% confidence interval would be from 108 to 165.
Step-by-step explanation:
Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:
78 = 87
97 = X
97 x 87/78 = X
8.439 / 78 = X
108.19 = X
78 = 133
97 = X
97 x 133/78 = X
12.901 / 78 = X
165.39 = X
Thus, the 97% confidence interval would be from 108 to 165.

Answer:
x = 32°
Step-by-step explanation:
∆KLM is an isosceles triangle because it has two equal sides, KL & KM. Therefore, the angles opposite to each of the two equal sides, which are referred to as the base angles are congruent to each other.
m<KML = m<KLM = 58°
m<MKL = 180 - (58 + 58) (Sum of triangle)
m<MKL = 64°
m<JKM = 180 - m<MKL (linear pair theorem)
m<JKM = 180 - 64 (Substitution)
m<JKM = 116°
∆JKM is also an isosceles triangle with two equal sides. Therefore, it's based angles (x & <J) would also be equal to each other.
Thus:
x = ½(180 - m<JKM)
x = ½(180 - 116) (Substitution)
x = 32°

Please someone help!! I tried my best to complete this problem but i'm stuck now (also am i even doing it right so far??!);(
Answer and Step-by-step explanation:
You got everything correct so far except for #4.
4. Yes, it is 1. But it would be in months.
So you would put:
1 month = x
12 months = 1 year.
Since the population increases by 1.5 times a month.
For question number 3.
The equation should be:
[tex]f(x) = 100(1.5)^x[/tex] <- Function
[tex]f(x) = 100(1.5)^{12}[/tex] <- Function when x is 12 months (1 year)
(Put those both the same way I put it.)
It gives you the equation to work with, you just have to plug in the values.
1.5 is in the parenthesis because it needs to be the one that is raised by an exponent.
100 is the initial population, so it stays on the outside.
x is the exponent

q/6 + 9 > 26
how would i find a solution to this?
===========================================================
Explanation:
We follow PEMDAS in reverse to isolate Q
Q/6 + 9 > 26
Q/6 > 26-9 ... subtract 9 from both sides
Q/6 > 17
Q > 17*6 .... multiply both sides by 6
Q > 102
We can have Q be any value larger than 102.
Note how the inequality sign stays the same the entire time. If we multiplied both sides by a negative number, then the inequality sign would flip; however, we multiplied both sides by a positive number.

Step-by-step explanation:
Simplify then graph it, find the x-intercept.
y = 3.75 + 1.5 (x - 1)
y = 1.5x + 2.25
When graphed, the x-intercept is 1.5
So it is, $1.50 per mile
Answer:
F. $1.50 per mile
Step-by-step explanation:
In order to solve this, you can first change it to slope-intercept form to find the slope, or rate of change, easier:
y = 3.75 + 1.5(x - 1) (given)
y = 3.75 + 1.5x - 1.5 (multiply 1.5 by each term in the parenthesis)
y = 2.25 + 1.5x (subtract 1.5 from 2.25)
y = 1.5x + 2.25 (order the terms by exponent value)
In slope-intercept form, the m (slope) of this equation is 1.5, so the rate of change is $1.50 per mile (with an initial fee of $2.25).
