Answer:
1/4
unsimplified = 2/8
Step-by-step explanation:
2/8 is your answer because
you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.
So hence, your answer is 1/4

Answer:
1/4
Step-by-step explanation:
From inspection of the box plot:
Minimum value = 100Q1 = 150Q2 (median) = 200Q3 = 225Maximum value = 275The left whisker (min value) to Q1 represents the bottom 25% of the data
Q1 to Q2 represents the second 25% of the data
Q2 to Q3 represents the third 25% of the data
Q3 to the right whisker (max value) represents the top 25%
Therefore, the sales of over $225 represent the top 25% of the data.
25% represented as a fraction is 25/100 = 1/4

What is the slope of a line perpendicular to the line whose equation is 2x-5y=-40
Answers
Answer:
[tex]2x-5y=-40\\-5y = -40-2x\\y = \frac{-40}{-5}-\frac{2x}{-5} \\y = \frac{2x}{5}+8[/tex]
Slope of a line perpendicular is [tex]\frac{-5}{2}[/tex]
Step-by-step explanation:
Hey there!
The given equation is ; 2x - 5y = -40.
Or, 2x - 5y + 40 = 0
Slope of the equation is;
[tex]slope(m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m = \frac{ - 2}{ - 5} [/tex]
[tex]m = \frac{2}{5} [/tex]
Therefore, the slope of equation is 2/5.
Now; For the perpendicular lines:
Slope of equation * slope of next line = -1
i.e M1*M2= -1
[tex] \frac{2}{5} \times m2 = - 1[/tex]
[tex]2 \: m2 = - 5[/tex]
[tex]m2 = \frac{ - 5}{2} [/tex]
Therefore, the slope of the line which is perpendicular line to 2x - 5y + 40= 0 is -5/2.

3v + 11 = 50 what’s the answer ?
Answers
Answer:
v=13
Step-by-step explanation:
3(13) = 39+11 = 50
Answer:
Our main goal is to isolate the variable here (v).
And if we want to solve this equation,
we must utilize inverse operations.
Given that:-
3v + 11 = 50
We always first get rid of the constants.
And in this case, 11 is our constant.
So the inverse operation of addition is subtraction (because 11 is being added)
-11 -11
3v = 39
Now, we are left with a co-efficient.
To isolate v, we must apply the inverse operation of multiplication which is division (because 3 and 'v' are being multiplied).
/3 /3
V = 13

b) Hence, or otherwise, work out what the
values of three consecutive even integers
must be if their sum is 6000.
Answers
Answer:
Below.
Step-by-step explanation:
a) Let the numbers be n, n + 2 and n + 4
Sum = n + n + 2 + n + 4
= 3n + 6.
As n must be even (2, 4, 6 and so on) , 3n must be divisible by 6 and 3n + 6 is divisible by 6 also.
b) 3n + 6 = 6000
3n = 5994
n = 5994/3 = 1998
So the numbers are 1998, 2000 and 2002.
The lengths of the red drum species of fish have an approximately Normal distribution, with a mean length of 24 inches and a standard deviation of 1.4 inches. What proportion of red drum fish are between 22 and 23.5 inches in length?
Answers
Answer:
0.2830
Step-by-step explanation:
edge
The required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
As per the given condition, if the fish is between 22 and 23.5 inches,
P(22≤ X ≤ 23.5)
You can rewrite it as:
⇒ P(X ≤ 22) - P(X ≤ 23.5)
The first step is to standard both values before using population data and the standard normal distribution to get the probability:
The formula of the standard normal is Z=(X-μ)/σ
⇒ P(Z ≤ (23.5-24)/1.4) - P(Z ≤ (22-24)/1.4) = P(Z ≤-0.36) - P(Z ≤ -1.43)
Now you look at the table of the Z-distribution for the cumulative probabilities for both z-score
⇒ (1 - 0.6406) - (1 - 0.9236)
⇒ 0.3594- 0.0764 = 0.2830
Hence, the required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

(25 -5√7)/3 ≈ 3.924 inches
Step-by-step explanation:
After removing squares from the corners and folding up the sides, the open-top box will have dimensions ...
x × (20 -2x) × (30 -2x)
The maximum value for this cubic expression in the domain 0 < x < 10 is found easily by a graphing calculator to be at x = 3.924 inches.
__
You can solve this by expanding the cubic and finding the solution that makes its derivative equal to 0.
V(x) = 4x^3 -100x^2 +600x
The derivative is ...
V'(x) = 12x^2 -200x +600 = 0
Dividing by 12, we have ...
x^2 -50/3x +50 = 0
Completing the square, we get the form ...
(x -25/3)^2 = -50 +(25/3)^2 = (-450 +625)/9 = 175/9
Taking the square root gives ...
x -25/3 = ±(5√7)/3
The solution in the desired range is ...
x = (25 -5√7)/3 ≈ 3.924 . . . inches
_____
Additional comment
We limit the value of x to half the width of the cardboard material, as any longer cuts would overlap to create a negative box dimension. The graph shows the maximum volume to be about 1056.3 cubic inches. Box dimensions would be 3.924 in deep by 12.153 in by 22.153 in.
__
The generic solution can be found using a similar procedure. For cardboard dimensions a×b, it will be ...
x = ((a +b) -√((a -b)² +ab))/6
How do you find the quotient of positive and negative decimals.
Answers
Answer:
Ok, so we know that you can't simply divide a decimal as it is (if you're using long division)
For example, let's take the quotient of 2.2 and -22
22÷ -2.2
so to get it into a whole number, multiply each value by 10 to get rid of decimal point
220 ÷ -22
when you divide, you are left with negative ten. Remember when you divide a negative and a positive number together, the result will always be negative

A high percentage of people who fracture or dislocate a bone see a doctor for that condition. Suppose the percentage is 99%. Consider a sample in which 300 people are randomly selected who have fractured or dislocated a bone. (i) What is the probability that exactly five of them did not see a doctor? (4 marks) (ii) What is the probability that fewer than four of them did not see a doctor? (5 marks) (iii) What is the expected number of people who would not see a doctor? (5 marks)
Answers
Answer:
(i) 0.15708
(ii) 0.432488
(iii) 3
Step-by-step explanation:
Given that, 99% of people who fracture or dislocate a bone see a doctor for that condition.
There is only two chance either the person having fracture or dislocation of bone will either see the doctor or not.
As per previous data, if one person got a fracture or dislocation of bone, the chance of seeing the doctor is 0.99. Assuming this chance is the same for every individual, so the total number of people having fractured or dislocated a bone can be considered as Bernoulli's population.
Let p be the probability of success represented by the chances of not seeing a doctor by any one individual having fractured or dislocated a bone.
So, p=1-0.99=0.01
According to Bernoulli's theorem, the probability of exactly r success among the total of n randomly selected from Bernoulli's population is
[tex]P(r)=\binom{n}{r}p^r(1-p)^{n-r}\cdots(i)[/tex]
(i) The total number of persons randomly selected, n=400.
The probability that exactly 5 of them did not see a doctor
So, r=5 , p=0.01
Using equation (i),
[tex]P(r=5)=\binom{400}{5}(0.01)^5(1-0.01)^{400-5}[/tex]
[tex]=\frac{400!}{(400-5)!\times 5!}(0.01)^5(0.99)^{395}[/tex]
=0.15708
(ii) The probability that fewer than four of them did not see a doctor
[tex]=P(r<4)[/tex]
[tex]=P(r=0)+P(r=1)+P(r=2)+P(r=3)[/tex]
[tex]=\binom{400}{0}(0.01)^0(0.99)^{400}+\binom{400}{1}(0.01)^1(0.99)^{399}+\binom{400}{2}(0.01)^2(0.99)^{398}+\binom{400}{3}(0.01)^3(0.99)^{397}[/tex]
[tex]=0.017951+0.072527+0.146154+0.195856[/tex]

Answers
The extra amount that Tim is expected to pay is approximately given by: Option D: $57.88
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, the question is missing the fact that the size of the tank is 11.75 gallon and a gallon of gas costs $4.50.
So, the total cost of 11.75 gallon of gas is:
Cost of 11.75 gallon gas = 11.75 * 4.50 = 52.875 (in dollars)
Also from the question, the cost of refueling a vehicle is $5.00.
So, the total cost for refueling the car of Tim is:
Total cost = cost of gas + cost of refueling the car
Total cost = 52.875 + 5.00
Total cost = $57.875 ≈ $57.88
Thus, the extra amount that Tim is expected to pay is approximately given by: Option D; $57.88

The rule of the mid-point of a segment whose endpoints are
([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is
[tex](x_{M},y_{M}) = (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]In our question
∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)
∴ [tex]x_{1}[/tex] = -15 and [tex]x_{2}[/tex] = x
∴ [tex]y_{1}[/tex] = 13 and [tex]y_{2}[/tex] = y
∵ The coordinates of the mid-point of this segment are (-24, 15)
∴ [tex]x_{M}[/tex] = -24 and [tex]y_{M}[/tex] = 15
→ Use the rule of the mid-point to find x and y
∵ [tex]-24=\frac{-15+x}{2}[/tex]
→ Multiply both sides by 2
∴ -48 = -15 + x
→ Add 15 to both sides
∴ -33 = x
∵ [tex]15=\frac{13+y}{2}[/tex]
→ Multiply both sides by 2
∴ 30 = 13 + y
→ Subtract 13 from both sides
∴ 17 = y
∴ The other endpoint is (-33, 17)
