When performing a t-test assuming unequal variances, the test statistic is a t-value, which is calculated by dividing the difference between the means of the two groups by the standard error of the difference.
To see if the difference in mean mpg between 4 and 8 cylinder cars is statistically significant, compare the estimated t-value to a critical t-value based on degrees of freedom and desired level of significance. The difference is regarded statistically significant if the estimated t-value is bigger than the crucial t-value.
As a result, the right response depends on the estimated t-value, the crucial t-value, and the level of significance utilized in the test.

Outcome 1 2 3 4 5 6
Frequency 8 11 6 14 9 12
Based on the table, what is the experimental probability that the number rolled was odd?
1 over 2
5 over 12
23 over 60
37 over 60
Answer:
[tex]\textsf{C)} \quad \dfrac{23}{60}[/tex]
Step-by-step explanation:
The odd number outcomes are 1, 3 and 5.
The probability for rolling each of the odd numbers is the frequency of the outcome divided by the total number of rolls.
[tex]\implies \sf P(x=1)=\dfrac{8}{60}[/tex]
[tex]\implies \sf P(x=3)=\dfrac{6}{60}[/tex]
[tex]\implies \sf P(x=5)=\dfrac{9}{60}[/tex]
Therefore, the experimental probability that the number rolled was odd is:
[tex]\begin{aligned}\sf P(x\;is\;odd)&=\sf P(x=1)\;or\;P(x=3)\;or\;P(x=5)\\\\&=\sf \dfrac{8}{60}+\dfrac{6}{60}+\dfrac{9}{60}\\\\&=\sf \dfrac{8+6+9}{60}\\\\&=\sf \dfrac{23}{60}\end{aligned}[/tex]

Find an equation of the line that satisfies the given conditions. Through (-9, -11); perpendicular to the line passing through (-6, 1) and (-2, -1)
Find an equation of the line that satisfies the given conditions.
Through (−9, −11); perpendicular to the line passing through (−6, 1) and (−2, −1)
An equation of the line that satisfies the given conditions is x = 2y + 13.
To find the equation of the line that passes through the point (-9, -11) and is perpendicular to the line passing through (-6, 1) and (-2, -1), we can use the slope-point form of a line.
First, we find the slope of the line passing through (-6, 1) and (-2, -1). The slope of this line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
Plugging in the values, we have:
m = (-1 - 1) / (-2 - (-6)) = -2 / 4 = -1/2
The slope of a line perpendicular to this line has a negative reciprocal, so the slope of the line through (-9, -11) that is perpendicular to this line is 1/2.
Next, we use the point-slope form of a line to find the equation of the line:
y - y1 = m (x - x1)
where (x1, y1) is a point on the line and m is the slope.
Plugging in the values, we have:
y - (-11) = 1/2 (x - (-9))
Expanding and simplifying, we get:
y + 11 = 1/2 (x + 9)
Multiplying both sides by 2, we get:
2y + 22 = x + 9
Subtracting 9 from both sides, we get:
2y + 13 = x
So, the equation of the line that satisfies the given conditions is:
x = 2y + 13

RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are: sin (x) , cos (x) and tan (x) , where:
sin (x) =[tex]\frac{opposite\ leg}{hypotenuse}[/tex]
cos(x)=[tex]\frac{adjacent\ leg}{hypotenuse}[/tex]
tan (x) = [tex]\frac{sin (x)}{cos(s)}= \frac{opposite\ leg}{adjacent\ leg}[/tex]
Therefore, for finding x you can apply the trigonometric ratio sin (x). See below:
sin (60) =[tex]\frac{opposite\ leg}{hypotenuse}=\frac{x}{22}[/tex], knowing that sin (60)=[tex]\frac{\sqrt{3} }{2}[/tex] you have
[tex]\frac{\sqrt{3} }{2}=\frac{x}{22} \\ \\ 2x=22\sqrt{3} \\ \\ x=11\sqrt{3}[/tex]
For finding y you can apply the trigonometric ratio tan (x). See below:
tan (60) =[tex]\frac{opposite\ leg}{adjacent\ leg}=\frac{x}{y}[/tex], knowing that tan (60)=[tex]\sqrt{3}[/tex] and x=[tex]11\sqrt{3}[/tex], you have

Let f(x)=sin(x) + 2 cos(x). Find the slope-intercept equation of the line tangent to the graph of y = f(x) at the point on the graph where x = 0. The equation of the tangent line is (write your answer in the form y =mx+b):
Answer:
Step-by-step explanation:
The first step is to find the slope of the tangent line. To do that, we need to find the derivative of f(x):
f(x) = sin(x) + 2cos(x)
f'(x) = cos(x) - 2sin(x)
Now we can find the slope of the tangent line at x=0 by plugging in x=0 into f'(x):
f'(0) = cos(0) - 2sin(0) = 1
Therefore, the slope of the tangent line at x=0 is 1.
Next, we need to find the y-coordinate of the point on the graph where x=0. To do that, we simply plug in x=0 into f(x):
f(0) = sin(0) + 2cos(0) = 2
Therefore, the point on the graph where x=0 is (0, 2).
Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is the point on the line. Plugging in m=1 and (x1, y1) = (0, 2), we get:
y - 2 = 1(x - 0)
Simplifying, we get:
y = x + 2
Therefore, the equation of the tangent line is y = x + 2.
Answer:
The equation of the tangent line at x = 0 can be found by differentiating the function f(x) and using the point-slope form of a line.
The derivative of f(x) is f'(x) = cos(x) - 2sin(x). Substituting x = 0 into f'(x) gives f'(0) = cos(0) - 2sin(0) = 1 - 0 = 1.
Therefore, the equation of the tangent line is y = 1x + b, or y = x + b.
To find the value of b, we can plug in x = 0 and y = f(0) = sin(0) + 2cos(0) = 2 into the equation. Solving for b, we get 2 = 0 + b, so b = 2.
Therefore, the slope-intercept equation of the line tangent to the graph of y = f(x) at the point (0,2) is y = x + 2.

Answer:
v = 1.165
Step-by-step explanation:
To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:0.4 - 0.167 = 0.2v0.233 = 0.2vNext, we can divide both sides by 0.2 to find the value of v:0.233 / 0.2 = 0.2v / 0.2v = 0.233 / 0.2v = 1.165So the value of v is 1.165.In conclusion, by subtracting 0.167 from both sides of the equation and dividing both sides by 0.2, we found that the value of v is 1.165.
Answer: The value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.
Step-by-step explanation:
To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:
0.4 - 0.167 = 0.2v
0.233 = 0.2v
Next, we can divide both sides by 0.2 to solve for v:
0.233 / 0.2 = 0.2v / 0.2
v = 1.165
So, the value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

Answer:
24%
Step-by-step explanation:
It’s easy all u have to do is add the 95% and 15%
And when u get the answer u add it with 1.10$ and boom u subtract the number and u get 24%.
Answer: $1.80 and $11.40
Step-by-step explanation:
We know that Chris was short on cash by $1.20, but we need to create an equivalent percentage.
95% + 15% = 110% (how much does it cost)
110% - 110% (how much he had) = 10% (amount short) = $1.20
10% = $1.20
100% (how much he had) = $12.00
Mouse = 95% of $12.00 (how much he had) = $11.40
Mouse pad = 15% of $12.00 (how much he had) = $1.80
Check your work:
$1.80 (Mouse pad) + $11.40 (Mouse) = $13.20
$13.20 - $12.00 = $1.20 (amount short)
We were correct!

PQRS is parallelogram. If QX = 13, then QS =
The QS would be QS = PQ(1 + PQ/13)
What are the sides and angles of a parallelogram?
S = (n 2) 180°, where 'n' specifies the number of sides in the polygon, can also be used to determine this.
Since PQRS is a parallelogram, opposite sides are parallel and equal in length. Therefore, we can say that PQ = SR and QS = PR.
If QX = 13, then we can use the fact that PQRS is a parallelogram to find the length of QS. We can draw a line segment from Q that is parallel to SR, and call the point where this line segment intersects PS as Y. This forms two triangles, QXY and QSR, which are similar because they share an angle and have parallel sides.
By the properties of similar triangles, we can set up a proportion:
QY/QX = QS/SR
Since QY is the same as PS, we can substitute PQ + QY for PS:
(QX + PQ)/QX = QS/SR
Substituting the value of QX and recognizing that PQ = SR, we get:
(13 + PQ)/13 = QS/PQ
Simplifying this equation, we get:
1 + PQ/13 = QS/PQ
Multiplying both sides by PQ, we get:
PQ + (PQ^2/13) = QS
Since PQ = SR and PQRS is a parallelogram, we know that SR = PQ, so we can substitute PQ for SR:
QS = PQ + (PQ^2/13)
Simplifying further, we get:
QS = PQ(1 + PQ/13)
Therefore, The QS would be QS = PQ(1 + PQ/13)

Write a polynomial function f of least degree that has a
leading coefficient of 1 and the given zeros. Write the
function in standard form.
Given zeros: -6,0,3-square root of 5
The least polynomial that contains the roots - 6, 0, 3 - √5 is equal to y = x⁴ - 5 · x³ - 2 · x² + 4 · x.
How to derive a polynomial function
In this problem we must determine a polynomial function that contains the following roots: - 6, 0, 3 - √5. By quadratic formula we understand the quadratic polynomial may contain two roots of this kind: x₁ = α + β and x₂ = α - β. Therefore, the complete set of roots of the least polynomial is:
x₁ = - 6, x₂ = 0, x₃ = 3 - √5, x₄ = 3 + √5
And the factor form of the least polynomial is:
y = (x + 6) · x · (x - 3 + √5) · (x - 3 - √5)
y = (x² + x) · [(x - 3)² - 5]
y = (x² + x) · (x² - 6 · x + 4)
y = x⁴ + x³ - 6 · x³ - 6 · x² + 4 · x² + 4 · x
y = x⁴ - 5 · x³ - 2 · x² + 4 · x

what does 40 oz mean in ml
Answer: 40 fluid ounces is approximately equal to 1182.94 milliliters.
Step-by-step explanation:
A fluid ounce (oz) is a unit of volume used in the United States and some other countries, while milliliters (ml) are used in the metric system. To convert ounces to milliliters, we can use the conversion factor of 29.5735 ml per fluid ounce.
So, 40 fluid ounces is equal to:
40 oz * 29.5735 ml/oz = 1182.94 ml
Therefore, 40 fluid ounces is approximately equal to 1182.94 milliliters.
Factor the polynomial: 10w^2-31w+15
Answer:
(5w - 3)(2w - 5)
Step-by-step explanation:
As this polynomial is of the form ax² + bx + c, where a = 10, b = -31, and c = 15 (and x = w), in this case, as a is a number other than 1, the first step is to multiply a and c, replacing c with that product and removing the coefficient from the w² term, giving us:
w² - 31w + 150 (as 10 × 50 is 150)
Now, we are looking for two numbers that when they're multiplied together you get c, which is 150, and those same two numbers when added together gives us b, -31.
After looking through all of the possible factors of 150, we see that -25 and -6 fulfill both of these requirements (as -25 × -6 = 150 and -25 + -6 = -31)
Now, as we have our two numbers we can set up our factors:
(w - 6)(w - 25)
However, as we had to get rid of the 10 in front of the w², we now have to bring it back in front of both w's, giving us:
(10w - 6)(10w - 25)
Now we look and see if we can simplify.
We can see that 10 and -6 can both be simplified by 2, giving us:
(5w - 3)(10w - 25)
We can also see that 10 and -25 can be simplified by 5, giving us:
(5w - 3)(2w - 5)
