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?
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.

What is the slope of a line perpendicular to the line whose equation is 2x-5y=-40
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.
Hope it helps....

Answer:
(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

Step-by-step explanation:1 third of 9 is 3. Half of 10 is 5. Multiply 5 by 3. It is now 15.
Answer:
15
Step-by-step explanation:
Work backwards:
half of 10 = 10 ÷ 2 = 5

a Show that the sum of any three
consecutive even integers is a multiple of 6.
b) Hence, or otherwise, work out what the
values of three consecutive even integers
must be if their sum is 6000.
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.

3v + 11 = 50 what’s the answer ?
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
The perimeter of a rectangular room is 32m.The length of a diagonal is 8m more than than the width.Find the dimensions of the room.
Answer: 12m by 4m.
Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.
Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.
w = x
l = x + 8
Use the equation for the perimeter.
P = 2l + 2w
Plug in your values:
32 = 2(x + 8) + 2(x)
Now, solve for x! First start by distributing the 2:
32 = 2x + 16 + 2x
Next, add like terms:
32 = 4x + 16
Subtract 16 from both sides:
16 = 4x
Divide by 4 on both sides:
4 = x
Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.
l = x + 8
Plug in your x and solve:
l = 4 + 8
l = 12
Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.
