Answer: x = 23
∠DBC = 23°
∠ABC = 157°
Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.
180 - 19 = 161
23 × 6 = 138
138 + 23 = 161
If x = 23°, then ∠DBC is 23°.
For ∠ABC, (6(x) + 19°
6(23) + 19°
6 × 23 = 138
138 + 19 = 157
∠ABC = 157°

What is the height of a cylinder with a volume of 936 pi cubic inches and a diameter of 24 inches? 1. 625 inches 4. 75 inches 6. 5 inches 39 inches.
The height of the cylinder with a volume of 936 pi cubic inches and a diameter of 24 inches is 5 inches.
The formula to calculate the volume of a cylinder is V = πr²h, where V represents the volume, r represents the radius, and h represents the height.
Given that the diameter of the cylinder is 24 inches, we can find the radius by dividing the diameter by 2. So the radius (r) is 24 inches / 2 = 12 inches.
We are also given that the volume of the cylinder is 936 pi cubic inches. Substituting the values into the formula, we have 936π = π(12²)h.
Simplifying the equation, we get 936 = 12²h.
Dividing both sides of the equation by 12², we find h = 936 / (12²) = 5 inches.
Therefore, the height of the cylinder is 5 inches. Option 6 is the correct answer.

Which one is correct for VIF of regression? Choose all applied.
a. Among Independent variables whose VIF is higher than 10, we eliminate one which is the least
related with dependent variable.
b. If there are 5 independent variables in a multiple regression, there are 5 VIF values available.
c. Among Independent variables whose VIF is higher than 10, we can eliminate more than one independent variables at the same time.
d. Elimination process of VIF is iterative process until all VIF values are smaller than 10 or close to 10.
The correct statements about the variance inflation factor (VIF) in regression are:
a. We eliminate one independent variable at a time from those with VIF higher than 10, starting with the one least related to the dependent variable.
c. It is possible to eliminate multiple independent variables simultaneously if their VIF values are higher than 10.
d. The elimination process of VIF is iterative until all VIF values are smaller than 10 or close to 10.
Statement b is incorrect because the number of VIF values available in a multiple regression is not necessarily equal to the number of independent variables.

The school supply store is selling two different sizes of similar folders. The smaller folder is 6 inches wide and 9 inches
tall. The larger folder is 12 inches tall.
What is the perimeter of the larger folder?
Answer:
The perimeter of the larger folder is 40 in
Step-by-step explanation:
This is because it says the two folders are similar this means that the width of the larger folder is 8 inches because the scale factor is 4/3. You can see this when you divide the length of the larger folder by the length of the smaller folder. So, if you solve 8+12+8+12 to find the perimeter you will get 40 inches

2.8*12=33.6

If r2ur = 0. 6873, r2r = 0. 5377, number of restrictions = 3, and n – k – 1 = 229, f statistic equals: a. 28. 6 b. 36. 5 c. 42. 1 d. 21. 2
The correct answer is (c) 42.1.
The F-statistic is used to test the overall significance of a regression model. In this case, we are given the values of the unadjusted coefficient of determination (r2ur), the adjusted coefficient of determination (r2r), the number of restrictions (p), and the degrees of freedom for error (n-k-1).
The F-statistic is calculated as F = ((r2ur - r2r)/p) / (1 - r2r)/(n-k-1)). Plugging in the given values, we get F = ((0.6873 - 0.5377)/3) / (1 - 0.5377)/(229) = 42.1.
The F-statistic is then compared to the critical value from the F-distribution table with p and (n-k-1) degrees of freedom and a significance level of α=0.05. If the calculated F-statistic is greater than the critical value, then we reject the null hypothesis and conclude that the model is statistically significant.
In this case, the calculated F-statistic of 42.1 is greater than the critical value, indicating that the model is statistically significant. Therefore, we can conclude that the regression model is a good fit for the data and that the independent variables are significantly related to the dependent variable.
In summary, the F-statistic is used to determine the overall significance of a regression model. It is calculated based on the unadjusted and adjusted coefficient of determination, the number of restrictions, and the degrees of freedom for error. The calculated F-statistic is then compared to the critical value to test the null hypothesis.

A rectangle has length (x+3)cm and width (x-2).Given that it's area is 50cm2,find the dimensions of the rectangle
Answer:
length- 10cm, width- 5cm
Step-by-step explanation:
You want to convert this into an algebraic equation.
Since a=lw, in this case, 50=lw. Subbing (x+3) for l and (x-2) for w, we get the equation (x+3)(x-2)=50.
Using FOIL, we can expand the brackets to make x²-2x+3x-6=50 and collect like terms to x²+x-6=50.
We want all the numbers on one side (to use the null factor law), so we subtract 50 from both sides. This gives x²+x-56=0.
From there, we factorise it, which becomes (x-7)(x+8)=0. (I used the cross method for this)
With the null factor law, one of the brackets must be equal to 0, meaning x-7=0 or x+8=0. This gives x as either 7 or -8.
With measurement, units must be positive, meaning it has to be 7. We can sub this for x in the 2 equations (length and width) to get the answers.
Length=x+3 becomes 7+3, which is 10cm.
Width=x-2 becomes 7-2, which is 5cm.
**This content involves writing, expanding, and factorising quadratic equations, and the null factor law which you may wish to revise. I'm always happy to help!
What is the area of this figure?
Answer:
264.5 yd²
Step-by-step explanation:
You want the area of the figure shown.
CompositionThe given figure can be decomposed into a triangle and two rectangles.
TriangleThe area of triangle ABH is ...
A = 1/2bh
A = 1/2(23 yd)(17 yd) = 195.5 yd²
RectanglesThe area of rectangle CDIH is ...
A = LW
A = (9 yd)(5 yd) = 45 yd²
The area of rectangle EFGI is ...
A = (6 yd)(4 yd) = 24 yd²
Total areaThe area of the figure is the sum of the areas of its parts:
total area = triangle area + rectangle CDIH area + rectangle EFGI area
total area = 195.5 yd² + 45 yd² + 24 yd²
total area = 264.5 yd²
aw Assume that w=f(s3 + 1?) and f'(x) = e* Find ow and at os ow 11 at ow 11 Os
The values of ow, ow', and ow'' are given by:
ow = f(s^3 + 1)
ow' = e^(s^3 + 1) * (3s^2)
ow'' = 3e^(s^3 + 1) * (3s^4 + 2s)
ow''' = 3e^(s^3 + 1) * (9s^3 + 2)
Based on the given information, let's determine the values of w', w'' and w'''.
Given:
w = f(s^3 + 1)
To find w', we need to use the chain rule. The derivative of w with respect to s is:
w' = f'(s^3 + 1) * (3s^2)
Given that f'(x) = e^x, we can substitute this into the expression:
w' = e^(s^3 + 1) * (3s^2)
To find w'', we differentiate w' with respect to s:
w'' = (e^(s^3 + 1) * (3s^2))' = (e^(s^3 + 1))' * (3s^2) + e^(s^3 + 1) * (6s)
Using the chain rule again, we get:
w'' = e^(s^3 + 1) * (3s^2) * (3s^2) + e^(s^3 + 1) * (6s)
Simplifying further:
w'' = 3e^(s^3 + 1) * (3s^4 + 2s)
To find w''', we differentiate w'' with respect to s:
w''' = (3e^(s^3 + 1) * (3s^4 + 2s))' = 3e^(s^3 + 1) * (9s^3 + 2)

What is a triangle?A triangle is a 3-sided polygon that is occasionally (though not very frequently) referred to as the trigon. Every triangle has three sides and three angles, some of which might be the same.
In a right triangle, the two sides opposite the right angle are referred to as the hypotenuse, and the other two sides are referred to as the legs. All triangles are bicentric and convex. The triangle's interior is that part of the plane it encloses; the exterior is the rest.
Given that ∆QPS ≈ ∆SRQ
a) ∠QPS = ∠QRS
106° = 2x + 12
106° - 12 = 2x
2x = 94°
x = 47°
b) ∠RSQ = ∠PQS
∠SQR + ∠SRQ + ∠RSQ = 180°
42° + 2(47°) + 12 + ∠RSQ = 180°
148 + ∠RSQ = 180°
∠RSQ = 180° - 148°
∠RSQ = 32°
∠PQS = 32°
c) ∠PSR = ∠PSQ + ∠RSQ
[ ∠PSQ = 42° = ∠SQR ; ∠RSQ = 32°]
∠PSR = 42° + 32°
∠PSR = 74°
Thus, In the given figure, where triangle QPS = triangle SRQ, the value of x = 47°, ∠PQS = 32°, ∠PSR = 74°.
