The percentage of fish which will have the lengths within 1 standard deviation of the mean is 68%.
What is Empirical Rule?Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.
According to empirical rule,
68% of the data lies in the standard deviation of ±1.
95% of the data lies in the standard deviation of ±2.
99.7% of the data lies in the standard deviation of ±3.
Given,
The lengths of a certain species of fish are approximately normally distributed with a given mean and standard deviation.
According to the Empirical Rule, 68% of the fish will have lengths within 1 standard deviation of the mean.
Hence the required percentage is 68%.

CITY |. Temperature (°F) St. Louis | 32 Montreal |. -18 Buffalo. | -8 Orlando. |. 68 Juneau. |. -26 By noon, the temperature In Buffalo had risen by 14 °F. What was the temperature there at noon? How much higher was the 6 a.M. Temperature in St. Louis than Juneau?
Answer:
6°F
58°F
Step-by-step explanation:
From the data Given :
Temperature rise in Buffalo by noon time = 14°F
The initial temperature at Buffalo = - 8°F
Rise in temperature = 14°F
Therefore, temperature at noon = (-8 + 14)°F = 6°F
B.)
Temperature at 6am in St. Louis = 32°F
Temperature at 6am in Juneau = - 26°F
Temperature difference :
(32 - (-26))°F
32 + 26
= 58°F
Temperature in St. Louis is 58°F higher
A soda can is made out of aluminum. It is 12
centimeters tall and has a diameter of 7.5
centimeters. How many cubic units of soda
would be needed to fill the can?
(Use 3.14 as PI)
Answer:
529.875 [tex]cm^3[/tex]
I don't know if they want it rounded or not, but rounded it would be 529.88 or 529.9
Step-by-step explanation:
Find the volume of the can (cylinder):
h = 12 cm
d = 7.5 cm
r = 1/2d = 3.75 cm
[tex]V=\pi r^2h\\\\= (3.14)(3.75)^2(12)\\\\= 529.875[/tex]

A circle with a radius of 4 inches has a diameter that is 3x+5 inches long. What is the value of x?
Answer:
x=1
Step-by-step explanation:
The radius of a circle is half of the diameter.
Because we know this, we can multiply the radius by 2 to equal the diameter:
4*2=3x+5
Then we solve for x:
8=3x+5
3=3x
x=1
Hello, can you please help me solve for the y intercept?
Answer:
The y-intercept is when the X is 0 And the y is whatever number it is. So in order to do that we need to find the pattern first and to do that we need to find the slope.
The slope here is 2/ 2 or 1.
So you add 1 to each side to find the next ordered pairs.
-5, -7
-4, -6
-3, -5
-2, -4
-1, -3
0, -2
So the y-intercept is -2.
3m + 2n + 4;
m = 2 and N =4
D2 + 9k; d = 10 and k =9
3m + 4y x 2 m = 7, y = 10
Answer:
1. 18
2. 181
3. 101
Step-by-step explanation:
They want you to take each equation, and replace the letter with the number they give you after the equation.
3m + 2n + 4; m = 2, n = 4
This becomes
3(2) + 2(4) + 4
We multiply before we add, according to the order of operations. So next, the equation becomes:
6 + 8 + 4
= 18
———-
D^2 + 9k ; D = 10, k = 9
Numbers squared are numbers multiplied by themselves.
(10)(10) + 9(9)
= 100 + 81 = 181
——————-
3m + 4y x 2 ; m = 7, y = 10
3(7) + 4(10) x 2
21 + 40 x 2
Remember, multiplication always comes before addition.
21 + 80 = 101

P(AUB), rounding to the nearest thousandth, if necessary.
Answer:
0.481
Step-by-step explanation:
P(A U B) = P(A) + P(B) - P(A∩B)
= 0.3 + 0.43 - 0.249

Step-by-step explanation:
A. Their rates of change differ by 2. B. Their rates of change differ by 4. C. Function M has a greater rate of change than Function P. D. Function M and Function P have the same rate of change.
Answer:
(a) Their rates of change differ by 2
Step-by-step explanation:
Given
See attachment for functions M and P
Required
Determine what is true about the rates of M and P
First, we calculate the slope (i.e. rate) of both functions.
Slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the table of M, we have:
[tex](x_1,y_1) = (-2,-9)[/tex]
[tex](x_2,y_2) = (2,11)[/tex]
So, the slope is:
[tex]m_M = \frac{11 --9}{2--2}[/tex]
[tex]m_M = \frac{20}{4}[/tex]
[tex]m_M = 5[/tex]
For function P, we have:
[tex]y = 7x + 9[/tex]
A function is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m = slope[/tex]
So, by comparison:
[tex]m_P = 7[/tex]
At this point, we have:
[tex]m_M = 5[/tex] --- Slope of M
[tex]m_P = 7[/tex] --- Slope of P
Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2
Other options are not true

The mean age of 5 people in a room is 33 years. A person enters the room. The mean age is now 37. What is the age of the person who entered the room?
Mean is the average,
The total ages with 5 people would be 5 x 33 = 165
the total ages with the 6th person is 6 x 37 = 222
The age of the 6th person is 222 - 165 = 57 years old.

a dress is regulary price a $45 thedress is marked down 30 percent what is sale price of the dress
Answer:
$31.50
Step-by-step explanation:
So first thing, it's necessary to figure out what 30% of 45 is.
You can set this up as an algebraic expression or your can multiple 45 by 3/10 to find out what that 30% is.
The algebraic expression would be 30% of 45 is x.
Using one of these two options; we would discover that 30% of 45 is 13.5.
However, this is not the answer, yet.
The question is looking for the price of the dress after the 13.5 is taken away.
Therefore, you would subtract.
45 - 13.5 = 31.5
Sooooo... your answer is "The sale price of the dress is $31.50."
