The weights are within 2 standard deviations of the mean are 8.9 lbs, 9.5 lbs and 10.4 lbs
How to determine the weights?The given parameters are:
Mean, μ = 9.5Standard deviation, σ = 0.5The weights within 2 standard deviation is represented as:
μ - 2σ ≤ x ≤ μ + 2σ
Substitute known values
9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)
Evaluate the product
9.5 - 1 ≤ x ≤ 9.5 + 1
Evaluate the sum
8.5 ≤ x ≤ 10.5
This means that the weights are between 8.5 and 10.5 (inclusive)
Hence, the weights are within 2 standard deviations of the mean are 8.9 lbs, 9.5 lbs and 10.4 lbs

solve for t in the proportions
t/3 = 5/1
t= ?
Answer:
t = 15
Step-by-step explanation:
[tex] = > \frac{t}{3} = \frac{5}{1} [/tex]
On cross multiplication,
[tex] = > t \times 1 = 5 \times 3 \\ = > t = 15[/tex]
Hope you've understood the solution.
Answer:
[tex]\boxed{\sf{t=15}}[/tex]Step-by-step explanation:
In proportions, you need to isolate t on one side of the equation.
Given:
[tex]\sf{\dfrac{t}{3}=\dfrac{5}{1} }[/tex]
[tex]\Longrightarrow: \sf{\dfrac{t}{3}=5}[/tex]
First, multiply by 3 from both sides.
[tex]\sf{\dfrac{3t}{3}=5*3}[/tex]
Solve.
Multiply the numbers from left to right.
5*3=15
Solutions:
[tex]\Longrightarrow: \boxed{\sf{t=15}}[/tex]
Therefore, the final answer is t=15.I hope this helps. Let me know if you have any questions.

The coordinates of point M are (2,4) and the coordinates of point N are (3,5) .
THE SLOPE OF M'N' is blank
Answer: 1
Step-by-step explanation:
0.8 is the slope of the line M'N'.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
So, the coordinates of M' are (0.82, 0.84) = (1.6, 3.2), and the coordinates of N' are (0.83, 0.85) = (2.4, 4).
Now, we can find the slope of line M'N' using the slope formula:
slope of M'N' = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (1.6, 3.2) and (x2, y2) = (2.4, 4).
slope of M'N' = (4 - 3.2) / (2.4 - 1.6)
the slope of M'N' = 0.8
Therefore, the slope of line M'N' is 0.8.

What is the slope-intercept equation of the line that contains the points (0, 3) and (1, 1)?
Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )
m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 2x + 3 ← equation of line

Which could be a step used when solving the equation 5x+10=7.5x?
Answer:
Putting all the x's to one side.
Step-by-step explanation:
By doing this, you would get:
10 = 2.5x
so,
4 = x
Answer:
We subtract 5x from both sides
Step-by-step explanation:
Step 1: Subtract 5x from both sides
[tex]5x + 10 = 7.5x[/tex]
[tex]10 + 5x - 5x = 7.5x - 5x[/tex]
[tex]10 = 2.5x[/tex]
Step 2: Divide both sides by 2.5
[tex]\frac{10}{2.5} = \frac{2.5x}{2.5}[/tex]
[tex]4 = x[/tex]
Answer: We subtract 5x from both sides

What are the values of a and b in the relative frequency table for the survey results? round answers to the nearest percent. a = 33%, b = 73% a = 68%, b = 43% a = 25%, b = 32% a = 33%, b = 43%
The values of a and b are 33% and 42.7% respectively.
Calculations and Parameters:Given:
The number of students that like blue uniform is only as 32,
The number of students that like gold uniform is only as 25,
The number of students that like blue and gold uniforms is 12
The number of students that like neither blue nor gold uniform as 6.
Then, the total number of students interviewed are 75 students.
The relative frequency of the students who like blue is 25, therefore,
25/75= 1/3= 0.33
= 33%
The relative frequency of the students that like blue but not gold is 32, therefore,
32/75= 0.427
