Find the 13th term of the geometric sequence 7,-35,175
Answers
Answer:1,708,984,375
Step-by-step explanation: Dont feel like doin those numbers but that's the answer :)
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
The nth term of a geometric sequence is given as,
nth term = a [tex]r^{n-1}[/tex]
The 13th term of the geometric sequence is 39062500.
What is a geometric sequence?A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Example:
2, 4, 8, 16, 32 is a geometric sequence.
We have,
7, -35, 175
a = 7
The common difference.
= -35 / 7
= -5
Now,
The nth term of a geometric sequence is given as,
nth term = a [tex]r^{n-1}[/tex]
Now,
n = 13
13th term:
= 7 x [tex](-5)^{13-1}[/tex]
= 7 x [tex](-5)^{12}[/tex]
= 39062500
Thus,
The 13th term of the geometric sequence is 39062500.

Find the value of x for which the lines l and m are parallel.
Question 6 options: A) 13 B) 5 C) 10 D) 4.7
Answers
Answer:
A) 13
Step-by-step explanation:
l // m
9x + 10 = 127
9x = 117
x = 13
The value of x for which the lines l and m are parallel is approximately 13. Hence, the correct option would be A) 13.
How to calculate the valueLet's solve the equation 9x + 10 = 127 to find the value of x:
9x + 10 = 127
Subtract 10 from both sides:
9x = 127 - 10
9x = 117
Divide both sides by 9:
x = 117 / 9
x ≈ 13
Therefore, the value of x for which the lines l and m are parallel is approximately 13. Hence, the correct option would be A) 13.

Stephanie gets an average of 11 calls during her 8 hour work day. What is the probability that Stephanie will get more than 4 calls in a 2 hour portion of her work day
Answers
Answer:
0.145
Step-by-step explanation:
Suppose λ = average number of an event occurring in an interval of a presented length; &
x = no. of events occurring in an interval length t
Thus, x has a Poisson distribution with parameter λt.
i.e.
[tex]P[X=k] = \dfrac{(\lambda t)^k\times e^{-\lambda t}}{k!} \ \ \ where; k = 0,1,2 ...[/tex]
Given that:
The average number of call every 8 hours = 11
Then, the parameter for the Poisson process [tex]\lambda =\dfrac{11}{8}[/tex]
where;
t = 2 hours
[tex]\lambda t = \dfrac{11}{8}\times 2[/tex]
[tex]\lambda t = \dfrac{11}{4}[/tex]
Also,
x = no. of calls occurring at an interval of length 2
The required probability is as follows:
P(x > 4) = 1 - [P ( x≤ 4) ]
[tex]=1 - [ P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) ][/tex]
[tex]= 1 - \bigg [ \dfrac{(\dfrac{11}{4})^0 \times e^{-11/4}}{0!}+\dfrac{(\dfrac{11}{4})^1 \times e^{-11/4}}{1!}+ \dfrac{(\dfrac{11}{4})^2 \times e^{-11/4}}{2!}+ \dfrac{(\dfrac{11}{4})^3 \times e^{-11/4}}{3!}+ \dfrac{(\dfrac{11}{4})^4 \times e^{-11/4}}{4!} \bigg ][/tex]
[tex]= 1 - \begin {bmatrix} 1 + \dfrac{11}{4} + \dfrac{\bigg (\dfrac{11}{4}\bigg)^2}{2}+\dfrac{\bigg (\dfrac{11}{4}\bigg)^3}{6}+\dfrac{\bigg (\dfrac{11}{4}\bigg)^4}{24} \end {bmatrix} e^{-11/4}[/tex]
[tex]= 1 - [ 1 + 2.75 + 3.78125 + 3.466145833 + 2.3829] \ e^{-11/4}[/tex]
= 1 - [13.38037]× 0.06393
= 1 - 0.855407
= 0.14459
≅ 0.145 ( to 3 decimal place)

Answers
Answer:
Step-by-step explanation:
3x + 5y = 7
Since that is our original form, let's convert it so that we can find the slope:
5y = -3x + 7
y = -3/5 x + y
To get a perpendicular line, we need the negative reciprocal of the slope. This means that the sign switches and numerator and denominator flip:
m = 5/3
From here, we use the point-slope equation and then convert that into slope-intercept form:
y - y1 = m(x - x1)
y - 6 = 5/3(x - 0)
y - 6 = 5/3x
