Answer:
5:11
Step-by-step explanation:
Since they are asking for apples there is only 5 apples cause they tell us.
For fruit you add all the fruit together minus the apples which is 11. I think.

Fill in the P(X = x) values in the table below to give a legitimate
probability distribution for the discrete random variable X, whose
possible values are 0, 1, 4, 5, and 6.
Value x of X P(X = x)
0 0.26
1 0.25
4 0.11
5
6
Answer:
P (X = 5) = a and P (X = 6) = 0.38 - a
Step-by-step explanation:
The sum of probabilities of all the events in a sample space is known is 1.
That is:
[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]
It is provided that, the random variable X, can assume values 0, 1, 4, 5, and 6.
The incomplete probability distribution is:
X P(X = x)
0 0.26
1 0.25
4 0.11
5 __
6 __
Compute the missing probabilities as follows:
[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]
[tex]P(X=0)+P(X=1)+P(X=4)+P(X=5)+P(X=6)=1\\\\0.26+0.25+0.11+P(X=5)+P(X=6)=1\\\\0.62+P(X=5)+P(X=6)=1\\\\P(X=5)+P(X=6)=1-0.62\\\\P(X=5)+P(X=6)=0.38[/tex]
Assume that P (X = 5) = a.
Here the value of a lies in the interval 0 ≤ a ≤ 0.38.
Then the value of P (X = 6) will be:
P (X = 6) = 0.38 - a
Thus, the complete probability distribution is:
X P(X = x)
0 0.26
1 0.25
4 0.11
5 a
6 0.38 - a

= neage Check Find the distance between the polnts (6,-5) and (-3,-5).
Answer:
The answer is
9 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are

Which is different? Find "both" answers.
Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
Step-by-step explanation :
As see that, AB is a line segment in which point C is represented in between the line.
As we are given that:
AC = 3
CB = 7
So,
AC + CB = 3 + 7 = 10
Similarly,
CA + BC = 3 + 7 = 10
Similarly,
AB = AC + CB = 3 + 7 = 10
But,
BC - AC = 7 - 3 = 4
From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.
Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
Answer:
Find BC-AC is the correct answer

1. National Geographic is reporting on the migration patterns of Canadian Geese. One of
the birds they are tracking traveled from Ottawa, Canada to Jackson, Mississippi
Part A: What units would be best to describe this situation
Part B: While writing the article for the next edition of National Geographic, the reporter
estimates that this goose flew 2,552,000 yards. How many significant digits does
the reporter's estimate have?
Part C: The Editor in Chief decided that the reporter chose the incorrect units. The editor
wants the reporter to convert the distance to miles. Complete this conversion.
Part D: Your younger brother determined that the distance from Jackson to Tucson
Arizona is 7,159,680 feet. He claims that this is further than the distance to
Ottawa. Is he correctJustify your answer using mathematical evidence.
Answer:
Part A: The unit that would be best to describes the situations is to the mile
Part B: 4 significant figures
Part C: 1,450 miles
Part D: He is not correct
Step-by-step explanation:
Part A: By unit conversion, we have;
1 mile = 1,760 yards
Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles
Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures
Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles
Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;
1 mile = 5,280 feet
Therefore;
7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles
Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;
The distance from Jackson to Tucson 1,356 miles [tex]\ngtr[/tex] 1,450 miles which is the distance from Jackson to Ottawa

Solve for n:
3/4f-5/2n=2
n=
Answer:
[tex]n=\frac{3f-8}{10}[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\frac{3}{4}f-\frac{5}{2}n=2[/tex]
First, remove all the fractions by multiplying by the LCM of the denominator.
The LCM of 4 and 2 is 4. Thus:
[tex]4(\frac{3}{4}f-\frac{5}{2}n)=4(2)[/tex]
Distribute:
[tex]4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)[/tex]
Simplify:
[tex]3f-10n=8[/tex]
Subtract 3f from both sides:
[tex](3f-10n)-3f=(8)-3f\\-10n=8-3f[/tex]
Divide both sides by -10:
[tex]n=\frac{8-3f}{-10}[/tex]
Divide by -1:
[tex]n=\frac{3f-8}{10}[/tex]
And this is our answer :)
n = (3f - 8)/10
Step-by-step explanation:3f/4 - ²⁾5n/2 = ⁴⁾2
3f - 10n = 8
3f - 8 = 10n
n = (3f - 8)/10

average speed of 7 km/h. How far did she go?
Answer:
5.83333333333 km
Step-by-step explanation:
14.40 until 15.30 is a total of 20 Minutes to 15:00 and andother 30 Minutes to 15:30 hr, so, she has been running for 50 Minutes.
Now solve for distance when 1 hr (60 min) = 7 km

if a bag of balloons consists of 47 white balloons, 5 yellow balloons, and 10 black balloons, what is the probability that a balloon chosen randonly from the bag will be black?
Answer:
10/62, 5/31, or 16.129%
Step-by-step explanation:
First you have to add all of the balloon colors together to get the entire sample size.
47 + 5 + 10 = 62
Next, you need to know the how many of the balloon colors you what the probabilty for that are in the sample size.
10 black balloons.
Finally, you divide the number of black balloons by total balloons to find the probability of randomly choosing one.
10/62 = 5/31 or 16.129%

So the equation is y= 5+2x
and x+y=44
So we use the substitution method and says that y=44-x
So 44-x=5+2x
simplify
44-5=3x

there's only one option with x=13
Answer: E. (13, 31)
Step-by-step explanation:
Let x= first number
Let y= Second number
----------------------------------
y-5=2x
x+y=44
--------------------------------
y=2x+5
x+y=44
----------------------------
x+(2x+5)=44 ⇔ substitute y value in terms of x
x+2x+5=44
3x+5=44
3x=39
x=13

A gym membership costs $25 to join and $14 each month. Write and use an algebraic expression to find the cost of the gym membership for 6 months.
Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:
[tex]f(x)=14x+25[/tex]
Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:
[tex]f(6)=14(6)+25\\f(6)=84+25\\f(6)=\$ 109[/tex]

Is "What is the area of the floor in this classroom?" a statistical question?
The answer is No
Explanation:
All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.
