Calculate the t-score for a sampling distribution mean of 10.5, a standard deviation of 1.5, and a size of 36 drawn from a population that has a mean of 10.
The t- score for a sampling distribution is 2
The t-score is the number of standard deviations from the mean in the t-distribution.
The upper and lower bounds of a confidence interval when the data are approximately normally distributed.
T-scores and confidence intervals
Confidence intervals use t-scores to calculate the upper and lower bounds of the prediction interval. The t-score used to generate the upper and lower bounds is also known as the critical t or t* value.
The t- distribution is given by
t=(x – μ) / (S / √n)
t = T – Distribution
x = sample mean
μ = population mean
S = standard deviation
n = Sample size
It is given that sampling distribution mean of 10.5, a standard deviation of 1.5, and a size of 36 drawn from a population that has a mean of 10.
We need to find the t-score for sampling distribution
t=(x – μ) / (S / √n)
Here, x= 10.5 , μ= 10, S=1.5, n=36
t = (10.5 - 10)/ (1.5 /√36)
t= 2
Hence the value of t-score is 2

It is the second answer.
Step-by-step explanation:
When numbers with the same base are multiplied, you add the bases.
1/2 + 3/4 is the same as
2/4 + 3/4 = 5/4
So now we have 2 ^5/4^2. When we have a power raised to a power. We multiply the powers.

Sort the data and find quartiles of the data set.
2.
Find the interquartile range of the data set.
3.
Find the lower fence and the upper fence for outliers.
4.
Find outliers if they exist.
Based on the dataset given, the first quartile is 38.75, and the third quartile is 45.25. This interquartile range is 6.5. The lower fence is 29 and the upper fence is 55.
What are the quartiles in the data?Order the sets:
31, 38, 39, 40, 41, 45, 45, 45,46, 58
First quartile position:
= 1(10 + 1) / 4
= 2.75th position
= 38 + 0.75 x (39 - 38)
= 38.75
Third quartile:
= 3(10 + 1) / 4
= 8.25th position
= 45 + 0.25 x (46-45)
= 45.25
Interquartile range:
= 45.25 - 38.75
= 6.5
Upper fence:
= 45.25 + (1.5 x 6.5)
= 55
Lower fence:
= 38.75 - (1.5 x 6.5)
= 29

3(1-5x)=2(3x+1) find the solution set
Answer:
1/21
Step-by-Step Explanation:
Let's solve your equation step-by-step.
3(1−5x)=2(3x+1)
Step 1: Simplify both sides of the equation.
3(1−5x)=2(3x+1)
(3)(1)+(3)(−5x)=(2)(3x)+(2)(1)(Distribute)
3+−15x=6x+2
−15x+3=6x+2
Step 2: Subtract 6x from both sides.
−15x+3−6x=6x+2−6x
−21x+3=2
Step 3: Subtract 3 from both sides.
−21x+3−3=2−3
−21x=−1
Step 4: Divide both sides by -21.
-21x/-21=-1/-21
x=1/21
[tex]\boldsymbol{\sf{3(1-5x)=2(3x+1)}}[/tex]
Reorder terms
[tex]\boldsymbol{\sf{3(-5x+1)=2(3x+1) }}[/tex]Distribute
[tex]\boldsymbol{\sf{-15x+3=2(3x+1) }}[/tex][tex]\boldsymbol{\sf{-15x+3=6x+2 }}[/tex]Subtract 3x from both sides.
[tex]\boldsymbol{\sf{-15x+3-3=6x+2-3 }}[/tex]Simplify
[tex]\boldsymbol{\sf{-15x=6x+1}}[/tex]Subtract 6x from both sides.

The given vertex and Focus are of a vertical parabola having an opening downward as the focus is in downward direction as the vertex.
Focus of the parabola can be written as :
[tex]\qquad \sf \dashrightarrow \: (h ,k+ a )[/tex]
where, h and k are coordinates of vertex
so,
k + a = -2 -1 + a = -2a = -1So, the equation of parabola can be written as :
[tex]\qquad \sf \dashrightarrow \: (x - h) {}^{2} = 4a(y - k)[/tex]
plug in the values ~
[tex]\qquad \sf \dashrightarrow \: (x - 1) {}^{2} = 4(- 1)(y + 1) {}^{} [/tex]
[tex]\qquad \sf \dashrightarrow \: (x - 1) {}^{2} = - 4(y + 1)[/tex]
Answer:
[tex](x-1)^2=-4(y+1)[/tex]
Step-by-step explanation:
Standard form of a parabola with a vertical axis of symmetry:
[tex](x-h)^2=4p(y-k) \quad \textsf{where}\:p\neq 0[/tex]
Vertex = (h, k)Focus = (h, k+p)Directrix: y = (k-p)Axis of symmetry: h = kIf p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards.Given:
vertex = (1, -1)focus = (1, -2)Comparing with the formulas:
⇒ h = 1
⇒ k = -1
⇒ k + p = -2 ⇒ -1 + p = -2 ⇒ p = -1
Substituting the values into the formula:
[tex]\implies (x-1)^2=4(-1)(y-(-1))[/tex]
[tex]\implies (x-1)^2=-4(y+1)[/tex]

You deposit $400 each month into an account earning 8% interest compounded monthly. Round to the nearest cent as needed. a) How much will you have in the account in 35 years? $ b) How much total money will you put into the account? $ c) How much total interest will you earn? $
If I deposit $400 each month into an account earning 8% interest compounded monthly, I will have $6,517 in my account in 35 years. The total money that I will put into the account is $168,000. I will earn a total compound interest of $6,117.
Calculating the Sum of Money in 35 yearsGiven information is as follows,
Principal, P = $400
Rate = 8%
Time, T = 35 years
n = 12 (Compounded monthly)
The amount for compound interest is given as,
A = [tex]P\frac{(1+\frac{R}{n} )^{nT} -1}{R/n}[/tex]
A = [tex]400\frac{(1+\frac{0.08}{12} )^{12.35} -1}{0.08/12}[/tex]
A = 6,517.02
A = $6,517 (to the nearest cents)
Calculating the Amount Put in AccountSince, $400 is deposited every month for 35 years,
Amount Put in 35 years for this compound interest =$400 × 12 × 35
= $168,000
Calculating the Compound InterestA = P + CI
Thus, the compound interest is given by,
CI = A - P
CI = 6517 - 400
CI = $6,117
I will earn a total interest of $6,117

The coordinates of the edges of the mini-solar cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60).
The distance between the two edges is 120 centimeters.
The equation for the parabolic mirror is x + 32 = (2/225) · y².
How to analyze a parabolical mini-solar cooker
Herein we must understand the geometry of the design of the mini-solar cooker to determine all needed information. The y-coordinates of the edges of the cooker are determined by Pythagorean theorem:
[tex]y = \pm \sqrt{(68\,cm)^{2}-(32\,cm)^{2}}[/tex]
y = ± 60
The coordinates of the edges of the mini-solar cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60). The distance between the two edges is 120 centimeters.
Lastly, the equation of the parabolic mirror can be determined based on the equation of the parabola in vertex form:
x - h = C · (y - k)² (1)
Where:
h, k - Coordinates of the vertex
C - Vertex constant
If we know that (h, k) = (- 32, 0) and (x, y) = (0, 60), then the vertex constant of the equation of the parabola is:
0 + 32 = C · 60²
C = 2/225
Then, the equation for the parabolic mirror is x + 32 = (2/225) · y².

waht is the x^2 + 10 = 0
Answer:
x = ±√10i (i outside the radical), or approximately ±3.62i, or no solution depending on your class.
Step-by-step explanation:
x^2 + 10 = 0
x^2 = -10
x = ±√-10
x = ±√10i (i outside the radical), or approximately ±3.62i.
The solution is not real.
If you meant x^2 - 10 = 0 then x = ±√10 or approximately ±3.62. This solution is real.

The points that are a horizontal distance of 6 and a vertical distance of 2 from the origin are (6, 2), (-6, 2), (6, -2), (-6, -2)
What are points?Points are undefined terms in geometry, however they are used to represent the coordinate or location of items in a coordinate plane
How to plot the point?The features of the point are given as:
Horizontal distance = 6
Vertical distance = 2
The above means that:
x = 6
y = 2
The points are then represented as:
(x, y) = ±(x. y)
So, we have
(x, y) = ±(6, 2)
When the above equation is expanded, we have
(x, y) = (6, 2), (-6, 2), (6, -2), (-6, -2)
