Answers
Answer:
A)+17311 represent the value in the statement.
B)-237 represent the value in the statement.
Step-by-step explanation:
A) The highest elevation in a country is Mt. Snowy with an altitude of 17,311 feet.
Elevation is in the positive direction
So, the positive integer will represent the given situation
So, The highest elevation in a country is Mt. Snowy with an altitude of +17311
Thus +17311 represent the value in the statement.
B)The lowest elevation in the country is Green Valley with an altitude of 237 feet below sea level.
Below the sea level means negative direction
So, the negative integer will represent the given situation
So, The lowest elevation in the country is Green Valley with an altitude of - 237 feet below sea level.
Thus -237 represent the value in the statement.

In a recent study, the Centers for Disease Control and Prevention reported that diastolic blood pressures of adult women in the United States are approximately normally distributed with mean 80.6 and standard deviation 10. (a) Find the 10th percentile of the blood pressures. (b) Find the 34th percentile of the blood pressures. (c) Find the third quartile of the blood pressures. Use the TI-84 Plus calculator and round the answers to at least two decimal places.
Answers
Answer:
A.) 67.78
B.) 76.48
C.) 87.34
Step-by-step explanation:
Given that:
Mean (m) = 80.6
Standard deviation (σ) = 10
A.) 10th percentile :
10th percentile corresponds to a Zscore of - 1.282
Zscore = (x - m) / σ
-1.282 = (x - 80.6) / 10
-12.82 = x - 80.6
x = -12.82 + 80.6
x = 67.78
B.)34th percentile of blood pressure ;
34th percentile corresponds to a Zscore of - 0.412
Zscore = (x - m) / σ
-0.412 = (x - 80.6) / 10
-4.12 = x - 80.6
x = - 4.12 + 80.6
x = 76.48
C.) third quartile = 75% = 0.75
75th percentile corresponds to a Zscore of 0.674
Zscore = (x - m) / σ
0.674 = (x - 80.6) / 10
6.74 = x - 80.6
x = 6.74 + 80.6
x = 87.34
a)The 10th percentile of blood pressure is 67.78.
b)The 34th percentile of blood pressure is 76.48.
c)The third quartile of the blood pressure is 87.34.
Mean blood pressure μ= 80.6
Standard deviation σ= 10
From the normal standard table, the z-score corresponding to the 10th percentile = - 1.282
What is a z-score?A z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
z= (x-μ) /σ
-1.282 = (x - 80.6) /10
-12.82 = x - 80.6
x = -12.82 + 80.6
x = 67.78
So, the 10th percentile of blood pressure is 67.78.
Similarly, the 34th percentile of blood pressure =76.48
The third quartile of the blood pressure =87.34
Therefore a) the 10th percentile of blood pressure is 67.78.
b)the 34th percentile of blood pressure is 76.48.
c)The third quartile of the blood pressure is 87.34.

Doing this without machine help requires you pick a form of the equation you want, fill in the x- and y-values for three of the given points, then solve the resulting equations for the unknown parameters. Usually, we use the form ...
y = ax^2 +bx +c
which will result in three linear equations for a, b, c. Those can be solved by any of the usual methods.

Lol I'll help you. So for the 1st problem, you need to subtract 7x from 4x but if your looking for and answer then x=2. For the 2nd problem subtract 3x-5x and 7 + 9 which brings you to -2x - 16 which means you would have to find x in this problem which means x has to be a negative. The negative answer is x= -32 since a negative x a negative is a positive. Which brings you to 16-16 and then 0. For the third one, you need to change the problem. Turn it into 5x - x = 4 + 8 which brings you to 4x = 12 making x =3. and for number 4 you need do the same as we just did and do 11x - 6x - 3x and then do 20 - 6 which brings you to 2x = 14 which makes x=7.

What is Sequence?An ordered collection of objects that allows repetitions is referred to as a sequence. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).
Given:
First term, [tex]a_1[/tex] = x
[tex]a_2[/tex] = 4[tex]a_1[/tex] + 20
.
.
.
[tex]a_n[/tex] = 4[tex]a_{n-1[/tex] + 20
So, [tex]a_n[/tex] = 868
4[tex]a_{n-1[/tex] + 20 = 868
4[tex]a_{n-1[/tex] = 868 - 20
[tex]a_{n-1[/tex] = 212
4[tex]a_{n-2[/tex] + 20 = 212
[tex]a_{n-2[/tex] = 48
and, [tex]a_{n-3[/tex] = 7

Answer:
Y-intercept: (0,-6)
X-intercept: (-8,0)
Step-by-step explanation:
In order to find an intercept, you have to know the difference in the two axis. The intercept is just where the plot line hits the axis. On the top, left side, you can see that the blue line his the black x-axis at -8 over to the right but it doesn't mover down. This means the x-intercept hits at (-8,0). On the upper, right side, you can see that the blue line his the black y-axis by not moving sideways, but it does go -6 down. This means that the y-intercept would be (0,-6).

Tickets for a drumline competition cost $5 at the gate and $3 in advance. One hundred more tickets were sold in advance than at the gate. The total revenue from ticket sales was $1990. How many tickets were sold in advance?
Answers
Answer:
The number of tickets sold at the gate is [tex] G = 211.25[/tex]
The number of tickets sold in advance is [tex] A = 311.25 [/tex]
Step-by-step explanation:
From the question we are told that
The cost of a tickets at the gate is [tex]a = \$ 5[/tex]
The cost of a ticket in advance is [tex]b = \$ 3[/tex]
Let the number of ticket sold in the gate be G
Let the number of ticket sold in advance be A
From the question we are told that
One hundred more tickets were sold in advance than at the gate and this can be mathematically represented as
[tex]G + 100 = A[/tex]
From the question we are told that
The total revenue from ticket sales was $1990 and this can be mathematically represented as
[tex]5 G + 3A = 1990[/tex]
substituting for A in the equation above
[tex]5 G + 3[G + 100]= 1990[/tex]
[tex]5 G + 3G + 300= 1990[/tex]
[tex] 8G + 300= 1990[/tex]
[tex] 8G = 1690[/tex]
=> [tex] G = 211.25[/tex]
Substituting this for G in the above equation
[tex]5 [211.25] + 3A = 1990[/tex]
=> [tex] 3A = 1990 - 1056.25[/tex]
=> [tex] A = 311.25 [/tex]
