A simple random sample of size n=53 is obtained from a population with μ=53 and σ=7. Does the population need to be normally distributed for the sampling distribution of x to be approximately normally distributed? Why? What is the sampling distribution of x?
Answer:
No, because the Central Limit Theorem posits that regardless of the shape of the underlying population, the sampling distribution of bar x becomes approximately normal as the sample size (n) increases.
The sampling distribution of x is;
[tex]\mu_{\overline x} = \mu = 53[/tex]
Step-by-step explanation:
Given that:
The sample size n = 53
The population mean μ = 53
The standard deviation σ = 7
The sampling distribution of x is;
[tex]\mu_{\overline x} = \mu = 53[/tex]
Sampling distribution of the standard deviation is:
[tex]\sigma _x =\dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]\sigma _x =\dfrac{7}{\sqrt{53}}[/tex]
[tex]\sigma _x =\dfrac{7}{7.28}[/tex]
[tex]\sigma _x =0.96[/tex]
Find the slope-intercept equation of the line that passes through (3,-1) and has an undefined slope
Answer:
Slope intercept equation would be: x - 3 = 0
Step-by-step explanation:
[tex]slope \: (m) = undefined = \frac{1}{0} \\ \\ \because \: line \: passes \: through \: the \: \\ point (3, \: - 1) = ( x_{1}, \: y_{1}) \\ \\ equation \: of \: line \: line \: in \: \\ point \: slope \: form \: is : \\ \\ y - y_{1} = m(x - x_{1}) \\ \\ y - ( - 1) = \frac{1}{0} (x - 3) \\ \\ y + 1 = \frac{1}{0} (x - 3)\\ \\ 0(y + 1) = (x - 3) \\ \\ 0 = x - 3 \\ \\ x = 3[/tex]
x=3 is the slope-intercept equation of the line that passes through (3,-1) and has an undefined slope.
If a line has an undefined slope, it means the line is vertical.
A vertical line has the equation of the form x = c, where c is a constant representing the x-coordinate of any point on the line.
The line passes through the point (3, -1), so the x-coordinate of any point on the line is 3.
Therefore, the equation of the line is x = 3.
If the slope-intercept form of a line (y = mx + b), it's not possible for a vertical line because it doesn't have a slope.
The slope-intercept form assumes a non-vertical line.
Hence, the equation of the line passing through (3, -1) with an undefined slope is simply x = 3.

Ellen reads an average of 33 pages per day from Monday through Friday and an average of 68 pages per day on the weekend. For each week, what is the average number of pages that Ellen reads per day?
Answer:
Ellen reads an average of 43 pages per day.

60x32 distribute 32 as 30+2 and solve, please! I really need help.
Answer:
1920
Step-by-step explanation:
First off, set 32 into standard form which is 30 + 2.
Secondly, multiply 30 x 60 and you get 1800
Thirdly, multiply 2 x 60 and you get 120
Lastly, add 1800 and 120 and you get 1920.
If you want it in a equation you can do 30 x 60 + 2 x 60 or (30+2) x 60.
-Cheers, Galaxy
After solving, this is written in the form of an equation which goes like this: 30 x 60 + 2 x 60 or (30+2) x 60.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. It is clear that a statement is not even an equation if there is no "equal to" sign in it.
Firstly, set 32 in standard form, that is :- 30 + 2.
Then, multiply 30 x 60 = 1800
Thirdly, multiply 2 x 60 = 120
Finally, add 1800 by 120 to get 1920.
You can accomplish it if you want it in an equation,
30 x 60 + 2 x 60 or (30+2) x 60.

What is the value of x?
O 2 units
O 3 units
O 5 units
08 units
Answer:
The value of x is 5 units ⇒ C
Step-by-step explanation:
In the given figure
∵ Δ ABC is a right triangle at vertex B
∵ AC is its hypotenuse
∵ BD ⊥ AC
∴ (BD)² = AD × DC
∵ BD = 10 units
∵ AD = x units
∵ DC = 4x units
→ Substitute them in the rule above
∴ (10)² = x × 4x
∴ 100 = 4x²
→ Divide both sides by 4
∵ [tex]\frac{100}{4}[/tex] = [tex]\frac{4x^{2}}{4}[/tex]
∴ 25 = x²
→ Take √ for both sides
∴ 5 = x
∴ The value of x is 5 units

What is the equation of the line of best fit that Mel drew?
Answer: the answer is y = 2/3x + 6
Step-by-step explanation: answer
The correct answer for the best line of fit is y = 2/3x + 6
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
In the scatter point it shows that the starting y-intercept is 6 and two of the options have a y-intercept of 15.
We have a picture of the line of fit if it has a slope of 1/3.
The 2/3 is the slope and 6 is the y intercept.
We know that Line of best of fit of the line shown in the scatter plot can be found by finding the slope (m) and the y-intercept (b) of the line then substituting each value into y = mx + b.
So, the correct answer is y = 2/3x + 6

A projectile is fired over horizontal ground from the origin with an initial speed of 60 m/s. What firing angles will produce a range of 300 m?
Answer:
[tex]54.75^\circ[/tex]
Step-by-step explanation:
Formula for horizontal distance or range is given as:
[tex]s=\dfrac{2v_i^2sin\theta cos\theta}{g}[/tex]
Where
[tex]v_i[/tex] is the initial velocity
[tex]\theta[/tex] is the angle with horizontal at which the projectile was thrown
[tex]g[/tex] is the acceleration due to gravity.
Given,
Initial velocity, [tex]v_i[/tex] = 60 m/s
Range, [tex]s[/tex] = 300 m
To find: [tex]\theta = ?[/tex]
Solution:
Using the formula as stated above:
[tex]300=\dfrac{2\times 60^2sin\theta cos\theta}{9.8}\\\Rightarrow 2sin\theta cos\theta =\dfrac{300\times 9.8}{3600}\\\Rightarrow sin2\theta =0.81666\\\Rightarrow \theta \approx \bold{54.75^\circ}[/tex]
