what is the temperature halfway between 20 degrees and -10 degrees?
Answer:
The temperature halfway is -5 degrees farenheit/celcious
Step-by-step explanation:
the difference is 30 degrees
30 / 2 = 15
20 - 15 = -5
-10 + 15 = -5

If n+1 integers are chosen from the set
1,2,3,…,2n
,where n is a positive integer, must at least one of them be even? Why?
Answer:
Pigeonhole Principle
Step-by-step explanation:
From series {1,2......2n} ; we need to select 'n + 1' integers.
Even integers series from above series = {2,4,6..........2(n-1), 2n}
Odd integers series from above series = {1,3,5........2(n-2), 2n-1}
So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.
Eg : n = 5, Series = (1,2,3,4,5,6,7,8,9,10}, Odd series = {1,3,5,7,9}, Even series = {2,4,6,8,10}. If we choose 5 +1 ie 6 integers, there must be one even integer, as there are only 5 total odd integers in series.please answer this :))))

Step-by-step explanation:
The daily revenue at a university snack bar has been recorded for the past five years. Records indicate that the mean daily revenue is $1200 and the standard deviation is $400. The distribution is skewed to the right due to several high volume days (football game days). Suppose that 100 days are randomly selected and the average daily revenue computed. Which of the following describes the sampling distribution of the sample mean?
a. skewed to the right with a mean of $1200 and a standard deviation of $400.
b. normally distributed with a mean of $1200 and a standard deviation of $40.
c. normally distributed with a mean of $1200 and a standard deviation of $400.
d. normally distributed with a mean of $120 and a standard deviation of $40.
Answer:
b. normally distributed with a mean of $1200 and a standard deviation of $40.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Skewed to the right, mean 1200, standard deviation [tex]\sigma = 400[/tex]
Sample of 100 days:
By the Central Limit Theorem:
Approximately normal
Mean 1200
Standard deviation [tex]s = \frac{400}{\sqrt{100}} = 40[/tex]
The correct answer is given by option b.

Half a circle, 4 in the center with arrows either side. what is the perimeter in cm
Answer:
Assuming you mean the diameter is 4 cm:
perimeter = 10.28 cm
Step-by-step explanation:
full circle perimeter = πD = (3.14)(4) = 12.56 cm
half circle = 12.56 cm/2 = 6.28 cm
flat side = 4 cm
6.28 cm + 4 cm = 10.28 cm

To use unit analysis to convert 7 feet to yards you could use: (DO NOT CONVERT!)To use unit analysis to convert 7 feet to yards you could use: (DO NOT CONVERT!)
Group of answer choices
7ft1⋅3yd1ft
(7 ft/ 1 ) multiplied by (3 yd/ 1ft)
7ft1⋅12in1ft
(7 ft/1) multiplied by (12 inches/1 ft)
7yd1⋅3ft1yd
None of these
7ft1⋅1yd3ft
Answer:
7ft/1yd ⋅1yd/3ft
Step-by-step explanation:
To use unit analysis to convert 7 feet to yards
Using unit analysis
1 yard = 3 feet
Hence
3 feet = 1 yard
7 feet = x yard
Cross Multiply
3 feet × x yard = 7 feet × 1 yard
We can represent this as
7 feet/1 yard × 1 yard/3 feet
The correct Option is :
7ft/1yd ⋅1yd/3ft

Use the ray tool to graph f(x)=−|x+2|
First plot the endpoint of the ray, then plot any point on the ray.
Answer: Graphed points I used, (-2,0), (0,-2), and (-3,-1)
Step-by-step explanation:
The graph of given function is attached below.
Absolute value function:The given function is,
[tex]f(x)=-|x+2|[/tex]
We have to draw the graph of above function.
When [tex]x=-2[/tex] , [tex]f(-2)=0[/tex]
When [tex]x=-4[/tex] , [tex]f(-4)=-|-4+2|=-2[/tex]
When [tex]x=0[/tex], [tex]f(0)=-2[/tex]
Thus, We have points [tex](-2,0),(-4,-2)[/tex] and [tex](0,-2)[/tex]

Answer:
Step-by-step explanation:
In the diagram, if WA = 6, AX = 5, and YA = 10, then the length of Y Z is
Answer:
YZ = 13 units
Step-by-step explanation:
By intersecting chords theorem in a circle,
YA × AZ = WA × AX
By substituting the values of each segment in the formula,
10 × AZ = 6 × 5
AZ = [tex]\frac{30}{10}[/tex]
AZ = 3 units
Therefore, YZ = AZ + AY
YZ = 3 + 10
YZ = 13 units
