The distribution of the number of transactions per day at a certain automated teller machine (ATM) is
approximately normal with a mean of 80 transactions and a standard deviation of 10 transactions. Which of
the following represents the parameters of the distribution?
ī=80; s = 10
B
I = 80; 92 = 10
I = 80; o = 10
D x = 80; o = 10
Ei=80; 8 = 10
Answer:
ī=80; s = 10
Step-by-step explanation:
When the standard deviation is from a finite group it is denoted by s. The number of transactions from an atm are countable in a day. So the standard deviation will be represented by s.
and ī represents the mean.
The other choices are incorrect because mean is usually represented by a bar over the alphabet such as x.
a simple alphabet does not denote the mean of the sample or population.
Parameters are the characteristics used to define a dataset.
The representation of the parameters are: [tex]\bar x = 80[/tex] and [tex]s = 10[/tex]
From the question, we have:
[tex]Mean = 80[/tex]
[tex]Standard\ Deviation = 10[/tex]
Mean is represented as: [tex]\bar x[/tex]
So, we have:
[tex]\bar x = 80[/tex]
Standard deviation is represented as [tex]\sigma[/tex] of s.
So, we have:
[tex]s = 10[/tex]
Hence, the representation of the parameters are:
[tex]\bar x = 80[/tex] and [tex]s = 10[/tex]

A baby blue whale can gain up to 200 pounds a day after it is born. If a baby blue whale has gained 7 x 103 pounds since its birth, how many days old is it?Express your answer
in standard notation.
Answer:
35 days
Step-by-step explanation:
Weight gain per day = 200 pounds
Weight gained by a whale since birth = [tex] 7*10^3 [/tex] pounds
Number of days of the whale = [tex] \frac{7*10^3}{200} = \frac{7*10*10*10}{200} [/tex]
[tex] = \frac{7*1000}{200} = \frac{7000}{200} = \frac{70}{2} = 35 [/tex]
In standard notation form, the whale is 35 days old.

Answer-
The slope of the line that passes through the points is
Solution-
As there is a single line passing through all these points, so taking any two points and then applying the formula for slope will give the slope of the line.
The points are,
(-14, 8), (-7, 6), (0, 4), (7, 2), (14, 0)
Taking two points as, (0, 4), (7, 2)
x₁ = 0
y₁ = 4
x₂ = 7
y₂ = 2
Putting the values,
Therefore, the slope of the line that passes through the points is
Step-by-step explanation:
The slope of the line that passes through the points in the table is -2/7.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Given a table which shows the points on the line.
Slope of a line passing through two points (x, y) and (x', y') is,
Slope = (y' - y) / (x' - x)
Take any two points on the line.
(0, 4) and (7, 2).
Slope = (2 - 4) / (7 - 0) = -2/7
Hence the slope of the line is -2/7.

Shannon was born on 12/21/1982. How many eight-digit codes could she make using the digits in her birthday?
Answer:
The value is [tex]Z = 1120 \ eight -digit \ code [/tex]
Step-by-step explanation:
From the question we are told that
The birth date of Shannon is 12/21/1982
Generally the number of digits present in her birth date is N = 8
Looking at the date we can see that 1 repeated 3 times
2 repeated 3 times
Generally the total number eight -digit code that she could make using her birthday given the total number of digits that make up her birth date is N = 8
is mathematically represented as
K = 8!
but but given that digit 1 repeated itself 3 times , and 2 repeated itself 3 times then the total number of eight -digit code that she could make using her birthday will be mathematically evaluated as
[tex]Z = \frac{K}{3 ! * 3!}[/tex]
=> [tex]Z = \frac{8!}{3 ! * 3!}[/tex]
=> [tex]Z = \frac{8* 7*6*5* 4 * 3!}{3 ! * 3* 2*1 }[/tex]
=> [tex]Z = 1120 \ eight -digit \ code [/tex]
Shannon could make 40,320 eight-digit codes using her digits in her birthday.
Given that Shannon was born on 12/21/1982, to determine how many eight-digit codes could she make using the digits in her birthday, the following calculation must be performed:
8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = X 56 x 30 x 12 x 2 = X 1680 x 24 = X 40320 = X
Therefore, Shannon could make 40,320 eight-digit codes using her digits in her birthday.

Question 3 of 8 Solve the equation below. 6/x^2+2x-15+7/x+5=2/x-3
I assume the equation is
[tex]\dfrac6{x^2+2x-15}+\dfrac7{x+5}=\dfrac2{x-3}[/tex]
Notice that
[tex]x^2+2x-15=(x+5)(x-3)[/tex]
so to get each fraction to have a common denominator, we need to rewrite
[tex]\dfrac7{x+5}=\dfrac{7(x-3)}{(x+5)(x-3)}=\dfrac{7x-21}{x^2+2x-15}[/tex]
and
[tex]\dfrac2{x-3}=\dfrac{2(x+5)}{(x+5)(x-3)}=\dfrac{2x+10}{x^2+2x-15}[/tex]
So we have
[tex]\dfrac6{x^2+2x-15}+\dfrac{7x-21}{x^2+2x-15}=\dfrac{2x+10}{x^2+2x-15}[/tex]
Combine the fractions and put them on one side:
[tex]\dfrac{6+(7x-21)-(2x+10)}{x^2+2x-15}=0[/tex]
If x ≠ -5 and x ≠ 3, we can ignore the denominator, leaving us with
[tex]6+(7x-21)-(2x+10)=0[/tex]
[tex](6-21-10)+(7x-2x)=0[/tex]
[tex]-25+5x=0[/tex]

The measure of angle ∠ZTB of triangle SRT is 31°.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
Let S R T be a triangle, and point Z is the in center of triangle S R T.
Lines are drawn from point Z to the sides of the triangle to form right angles and line segments Z A, Z B, and Z C as shown in the below figure.
Here, ∠ AZR = 35°, ∠ZRC = 35°, ∠ BSZ = 24°, ∠ZSA = 24°, ∠ZTB = ?
The in center of a triangle is the intersection point of all the three interior angle bisectors of the triangle. It can be defined as the point where the internal angle bisectors of the triangle cross.
According to the angle bisector theorem,
⇒ [tex]\angle ZRC = \angle ARZ[/tex]
⇒ [tex]\angle ARZ = 35\degree[/tex]
Let the unknown angle, ∠ZTB be x. Then ∠BTC = 2x
The sum of the interior angles of a triangle is equal to 180°,
So, [tex]24+24+35+35+2x=180[/tex]
⇒ [tex]118+2x=180[/tex]
⇒ [tex]2x=180-118[/tex]
⇒ [tex]x=\frac{62}{2}[/tex]
⇒ [tex]x=31[/tex]
Hence we can conclude that the measure of angle ∠ZTB of triangle SRT is 31°.

Answer:
A) Slope =
[tex]m = \frac{1}{4} x[/tex]
explanation:
Take 2 random points off the line, I used (4,1) & (8,2)
The formula to find the slope when given 2 points is
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
so in this case x1 & y1 are assigned to (4,1)
4 = x11 = y1and x2 & y2 are assigned to (8,2)
8 = x22 = y2so substitute the numbers into the formula and solve !
[tex] m= \frac{y2 - y1}{x2 - x1} = \frac{2 - 1}{8 - 4} = \frac{1}{4} [/tex]
this will result in the answer I got above!!
B) yes it does show a constant rate of change cause it's increasing in 1/4x intervals
C) just because you move the placement of a line on the graph doesn't mean it's going to effect the slope as long as the numbers on the axis don't change!!

Suppose tan(b) = -2, and the terminal side of b is located in quadrant II. What is cot(b)?
Suppose tan(b) = -2, and the terminal side of b is located in quadrant II, then cot(b) = -1/2
Note that:
tan(b) = Opposite/Adjacent
Comparing the above relationship with tan(b) = -2/1:
Opposite = -2
Adjacent = 1
Also note that:
cot(b) = 1/tan(b)
cot(b) = Adjacent/Opposite
Substitute opposite = -2 and adjacent = 1 into the expression for cot(b)
cot(b) = -1/2
