Answer:
19
Step-by-step explanation:
TU is 2 inches and UV is 17 so adding them together would equal TV which is 19.
Answer: 19
Step-by-step explanation:
Because point U is found on both TU and UV, we can assume that this point is a bisector, dividing line TV into two separate lines. This essentially tells us that when we add lines TU and UV together, they will equal the length of line TV. With that being said, 2 + 17 = 19, so that is the length of TV. Hope this helps!
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
2, 6, 10,..
Find the 41st term.
The given sequence appears to be an arithmetic sequence, as the common difference between consecutive terms is 4.
The nth term of an arithmetic sequence is given by the formula: a_n = a_1 + (n-1)d, where a_1 is the first term, d is the common difference and n is the nth term.
Given that the first term of the sequence is 2, the common difference is 4.
To find the 41st term of the sequence, we can use the formula:
a_41 = 2 + (41-1) * 4 = 2 + 40 * 4 = 2 + 160 = 162
Therefore, the 41st term of the sequence is 162.

A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation. The degree indicates the highest exponential power in the polynomial (ignoring the coefficients).
For example: 6x4 + 2x3+ 3 is a polynomial. Here 6x4, 2x3, 3 are the terms where 6x4 is a leading term and 3 is a constant term. The coefficients of the polynomial are 6 and 2.
The degree of the polynomial 6x4 + 2x3+ 3 is 4.
(c) use the answers to parts (a) and (b) to estimate by how much the average monthly cell phone bill changed between 1990 and 2008. (round your answer to two decimal places.)
The area above x axis is 12.6 sq units while the area under the y-axis is 42.443 sq units. The change in the average phone bill is 29.843 units.
a) Here we see that the graph is in the shape of a right-angled triangle above the x-axis
The area of a triangle = 1/2 X Base X Height
Here the base will be the measure of the distance of co-ordinates on the x-axis
The height is the distance between the coordinates on the axis for that triangle
= 1/2 X (16 - 8) X (3.15 - 0)
= 1/2 X 8 X 3.15
= 12.60 sq units
b)
Below the x-axis, the graph is a rectangle and a triangle
The area of the rectangle = length X width
Here length is the distance of the co-ordinates of the y-axis and width is the distance between the coordinates for the x-axis
Hence we get
(0 - (-5.14))(8 - 0)
= 5.14 X 8
= 41.12 sq units for the rectangle.
The area of the triangle will be
1/2 X (18 - 15.48) X (0 - (-1.05))
1/2 X 2.52 X 1.05
= 1.323 sq unit
Hence, the total area is
41.12 + 1.323
= 42.443 sq unit
c)
Since the area under the graph represents change,
Here we see that the change in the average cell phone bill will be
42.443 + 12.6
= 55.043

at a local veterinary office, 48% of dogs get their teeth cleaned, while 35% of cats get their teeth cleaned. let p hat subscript upper d and p hat subscript upper c be the sample proportions of dogs and cats at this veterinary office, respectively, who get their teeth cleaned. suppose 25 dogs and 32 cats from this veterinary office are selected at random to collect data on their teeth-cleaning history. which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat subscript upper d baseline minus p hat subscript c ?
The difference (Dogs – Cats) in the sample proportions of those that get their teeth cleaned typically varies about 0.054 from the true difference in proportions.
The third option is correct.
What is the standard deviation?
Standard deviation is a statistical measure of the spread of a dataset, defined as the square root of its variance. It is a way to quantify the amount of variation or dispersion of a set of data values.
Percentage of Dogs getting their teeth cleaned = 48% = pD
Percentage of Cats getting their teeth cleaned = 35% = pC
Number of Dogs selected = nD = 25
Number of Cats selected = nc = 32
As the sample sizes are large enough, we can apply Central Limit Theorem
According to Central Limit Theorem for proportions –
pD-hat ~ Normal(pD, {pD*(1-pD)}/nD)
Thus, pD-hat ~ Normal(0.48, 0.009984)
Similarly,
pC-hat ~ Normal(pC, {pC*(1-pC)}/nC)
Thus, pC-hat ~ Normal(0.35, 0.0071094)
Now if X ~ N(E(X), Var(X)) and Y ~ N(E(Y), Var(Y))
then X -Y ~ N(E(X)-E(Y), Var(X)-Var(Y)) (If X and Y are Independent)
Thus,
pD-hat - pC-hat ~ Normal(0.48-0.35, 0.009984 – 0.0071094)
pD-hat - pC-hat ~ Normal(0.13, 0.0028746)
Thus, Standard Deviation of pD-hat - pC-hat = (0.0028746^0.5) = 0.0536 that is 0.054 approximately
Hence, the difference (Dogs – Cats) in the sample proportions of those that get their teeth cleaned typically varies about 0.054 from the true difference in proportions.
Third Option is correct.

Step-by-step explanation:
Solve the homogeneous differential equation in terms of x and y. A homogeneous differential equation is an equation of the form M(x, y) dx + N(x, y) dy = 0, where M and N are homogeneous functions of the same degree. To solve an equation of this form by the method of separation of variables, use the substitutions y = vx and dy = x dv + v dx.
(x^3 + y^3) dx − xy^2 dy = 0
The solution to the differential equation (x^3 + y^3) dx − xy^2 dy = 0 is y/x^3 = Ce^(−(y/x)^3), where C is an arbitrary constant.
Substituting y = vx and dy = x dv + v dx, we get:
(x^3 + (vx)^3)dx − x(vx)^2(x dv + v dx) = 0
Simplifying and rearranging, we get:
x^2v dx + (x^3 + 3xv^2 − v^3x^2)dv = 0
Dividing both sides by x^2v and rearranging, we get:
dx/x + (1/v)dv + (3/xv - v^2)dv = 0
Integrating both sides, we get:
ln|x| + ln|v| + 3ln|v/x| − v^3 = C
Where C is an arbitrary constant. Simplifying, we get:
ln|vx/x^3| = C − v^3
Rearranging, we get:
vx/x^3 = Ce^(−v^3)
Finally, we can express this in terms of x and y as:
y/x^3 = Ce^(−(y/x)^3)
The solution to the differential equation (x^3 + y^3) dx − xy^2 dy = 0 is y/x^3 = Ce^(−(y/x)^3), where C is an arbitrary constant.

A client who weighs 70 kg is receiving a dopamine solution of 800 mg/500 ml normal saline at 5 ml/hour. How many mcg/kg/minute is the client receiving? (Enter the numeric value only. If rounding is required, round to the nearest tenth.)
To calculate the mcg/kg/minute, first divide 800 mg by 500 ml to get 1.6 mg/ml. Then, multiply 1.6 mg/ml by 5 ml/hour to get 8 mg/hour. Finally, divide 8 mg/hour by 70 kg to get 0.114 mcg/kg/minute.
To calculate the mcg/kg/minute, first divide 800 mg by 500 ml to get 1.6 mg/ml, which is the concentration of dopamine in the solution. Next, multiply 1.6 mg/ml by 5 ml/hour to get 8 mg/hour, which is the rate of infusion. Finally, divide 8 mg/hour by 70 kg to get 0.114 mcg/kg/minute, which is the mcg/kg/minute the client is receiving. This calculation can also be done by dividing 800 mg by 500 ml to get 1.6 mg/ml, then multiplying 1.6 mg/ml by 5 ml/hour to get 8 mg/hour, and finally dividing 8 mg/hour by 70 kg to get 0.114 mcg/kg/minute.

Which sign makes the following statement true?
1/4 _____ 5/16
Answer:
2. <
Step-by-step explanation:
To compare these two fractions we can first find them a common denominator. A common denominator between 4 and 16 is 16.
To get from 16 from 4 we multiply by 4 so we do the same to the numerator, changing 1/4 to 4/16.
5/16 already has a denominator of 16 so we can leave that one as is.
4/16___5/16
In this form it is obvious that 5/16 is the larger fraction because 5 is larger than 4, meaning that 5/16 is larger than 1/4.

The linear equation in two variables is -5X + 10 = Y
What is linear equation?A linear equation in mathematics is an equation that may be written as follows: Y = aX + b where a and b are the coefficients, which are frequently real numbers, and X and Y are the variables (or unknowns). As long as they don't contain any of the variables, the coefficients can be thought of as equation parameters and can be arbitrary expressions. The coefficients must not all be 0 in order to produce a meaningful linear equation.
A linear polynomial over a field, from which the coefficients are taken, can also be equalised to zero to produce a linear equation.
Such an equation's solutions are the values that, when used as placeholders for the unknowns, result in the equality being true.
Let us assume that given equation as linear equation in two variables
Y = aX + b
Also, from the given table, the value which satisfy the equations are
X =3, Y = -5 and X = 4, Y = -10
using these values we have
-5 = 3a +b and -10 = 4a +b
subtracting both the equations we get,
-5 = a
Now putting this value in an equation we get
