Answer:
x=33
Step-by-step explanation:
x+13+4x+2=180
4x+x=5x
13 plus 2 =15
5x+15=180
subtract 15 from both sides
180-15=165
5x=165
divide 5 from both sides
x=33

A student group at NAU collected information from a local dine in resturant indicating the tip amount left by customers over the course of a two year period. The tip amounts were roughly normally distributed with a mean of $7.84 and a standard deviation of $2.60
Answer:
The desired range will be "($ 2.64, $ 13.04)".
Step-by-step explanation:
The query given seems to be missing. Kindly check find the entire questions attachment.
The given values are:
Mean
= $ 7.84
Standard deviation
= $ 2.60
Those are established by empirical rule whether 95% including its values cheat throughout two standard deviations of such the mean, for something like a roughly normal distribution results.
Thus, the range of values which might absorb 95% of all sums will be:
= [tex](Mean - 2\times Standard \deviation, Mean + 2\times Standard \ deviation)[/tex]
On putting the estimated values, we get
= [tex](7.84 - 2\times 2.60, 7.84+ 2\times 2.60)[/tex]
= [tex](7.84-5.2, 7.84+5.2)[/tex]

Solve the system of equations 9x-6y=-12 and 8x-5y=-8 by combining the equations
Answer:
(x, y) = (4, 8)
Step-by-step explanation:
We can multiply the first equation by -8 and the second by +9, then add the result.
-8(9x -6y) +9(8x -5y) = -8(-12) +9(-8)
-72x +48y +72x -45y = 96 -72
3y = 24
y = 8
Substituting for y in the first equation, we have ...
9x -6(8) = -12
9x = 36 . . . . . . add 48
x = 4
The solution is (x, y) = (4, 8).

1. & 2. In the diagram below, points A, B, and C are collinear. Answer each of the following questions. The figure shown below is not drawn to scale, meaning you cannot determine your answers by using your ruler.
Answer:
a). AB = 8 in
b). AB = 9.75 in
c). AC = 6.5 in
d). BC = 1.5 in
Step-by-step explanation:
a). Since, AB = AC + CB
Length of AC = 5 in. and CB = 3 in.
Therefore, AB = 5 + 3 = 8 in.
b). Given : AC = 6.25 in and CB = 3.5 in
Therefore, AB = AC + CB = 6.25 + 3.5
AB = 9.75 in.
c). Given: AB = 10.2 in. and BC = 3.7 in.
AB = AC + BC
AC = AB - BC
AC = 10.2 - 3.7
AC = 6.5 in
d). Given: AB = 4.75 in and AC = 3.25 in.
BC = AB - AC
BC = 4.75 - 3.25 = 1.5 in.
8.) Write an inequality that can be used to represent this situation, where x represents Olivia’s sister’s age. (Short answer)
Olivia is 6 years older than her sister. The sum of their ages is no more than 28 years.
Bonus: What is the oldest age her sister can be?
please show work!! It took me ages to try to solve this!
thank you future answers! :D
Answer:
The oldest age of Olivia’s sister can be 11 years.
Step-by-step explanation:
Given: Olivia’s sister’s age is x years.
To write: inequality that can be used to represent the given situation.
As Olivia is 6 years older than her sister,
Olivia's age [tex]=x+6[/tex]
As the sum of their ages is no more than 28 years,
[tex]x+(x+6)\leq 28\\2x+6\leq 28\\2x\leq 28-6\\2x\leq 22\\x\leq \frac{22}{2}\\ x\leq 11[/tex]
So, the oldest age of Olivia’s sister can be 11 years.
Solve for n 11(n – 1) + 35 = 3n
Answer:
n=-3
Step-by-step explanation:
Given: 11(n-1)+35=3n
Multiply 11 with the parenthesis. 11n-11+35=3n
Combine like terms. 11n+24=3n
Take 3n away from each side. 8n+24=0
Take 24 away from each side. 8n=-24
Divide each side by 8. n=-3
First decide whether the angles are congruent or supplementary, then solve for x.

Jon is 5 years older than Dana. Ella is twice as old as Jon and Zach is twice as old as Dana. The sum of their ages is 93. How old is Jon?
Answer:
Dana's age = 13 years
Zach's age = 26 years
Jon's age= 18 years
Ella's age = 36 years
Step-by-step explanation:
Let
Dana's age = x
Zach's age = 2x
Jon's age= x + 5
Ella's age = 2(x + 5)
Sum of their age = 93
x + 2x + (x + 5) + 2(x + 5) = 93
x + 2x + x + 5 + 2x + 10 = 93
6x + 15 = 93
Subtract 15 from both sides
6x + 15 - 15 = 93 - 15
6x = 78
Divide both sides by 6
x = 78/6
= 13
Therefore,
Dana's age = x = 13 years
Zach's age = 2x
= 2(13)
= 26 years
Jon's age= x + 5
= 13 + 5
= 18 years
Ella's age = 2(x + 5)
= 2(13+5)
= 26+10
= 36 years
Dana's age = 13 years
Zach's age = 26 years
Jon's age= 18 years
Ella's age = 36 years
Sum of their age = 13 + 26 + 18 + 36
= 93 years

Which is an example of structured observation?
A. A parent visits her son's second-grade classroom to
observe his behavior.
B. A zoo employee observes a new gorilla's interaction
with the other gorillas in the enclosure.
C. A new employee sits beside a veteran employee to see what types of situations occur during a normal work
day.
D. After receiving an anonymous tip, a supervisor
observes his staff to see if any of them are downloading music while they should be working.
The example of structured observation is when a new employee sits beside a veteran employee to see what types of situations occur during a normal work
For better understanding, let's explain what structure observation means
Structured Observation is simply refered to as method or technique often used for data collection. it is said to rely on wide or explicit rules for observing, categorizing, and recording behaviour of all types.There is direct observation of behaviour of which is not often used due to the fact that there is limited access to some social spaces and difficulty in capturing some behaviours. It is made up of smaller sample sizes.From the above we can therefore say that the answer The example of structured observation is when a new employee sits beside a veteran employee to see what types of situations occur during a normal work is correct
