Answer:

Answer: D

Step-by-step explanation:

To construct a 95% confidence interval for the difference between the means, we use the formula:

CI = x1 - x2 ± t*SE where x1 and x2 are the sample means, SE is the standard error of the difference, and t is the critical value from the t-distribution for a given confidence level and degrees of freedom.

SE = sqrt(s1^2/n1 + s2^2/n2) where s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes.

The degrees of freedom can be calculated as:

df = n1-1 + n2-1 = 34 + 39 = 73

Using a t-distribution table with a confidence level of 95% and df=73, the critical value t is 1.996.

Plugging in the values, we have:

CI = 19.4 - 15.1 ± 1.996 * sqrt(1.4^2/35 + 0.8^2/40)

CI = 4.3 ± 1.996 * 0.38

CI = 4.3 ± 0.77

CI = (3.53, 5.07)

Therefore, the 95% confidence interval for the difference between the mean burning time of brand X and brand Y is (3.53, 5.07) minutes. So, the answer is D) 3.6 min.

The rate of the gas left in the tank will be -6 and the equation will be given as y = -6x + 20.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that:-

The rate of gas will be calculated as:-

Suppose the hours are represented by x and the gallons are represented by y.

The rate of the gas will be the slope so the slope will be calculated as:-

\(m =\dfrac{y_2-y_1}{x_2-x_1}\)

\(m = \dfrac{2-20}{3-0}\)

\(m =\dfrac{-18}{3}\)

m = -6

The equation will be given as:-

y = mx + c

y  = -6x + 20

Therefore the rate of the gas left in the tank will be -6 and the equation will be given as y = -6x + 20.

The following formula can be used to create permutations of n objects with repeats of k1, k2,..., kr objects of each type:

=> n!/(k1! * k2! * ... * kr!)

We have two different object kinds (A and B) here, both of which are repeated twice. As a result, we have:

n = 4 (the total number of things) (the total number of objects)

=>k1 = k2 = 2 (the number of objects of each category) (the number of objects of each type)

Answer:

No, the Normal/large sample condition is not met. A confidence interval assumes that the underlying population follows a normal distribution and that the sample size should be at least 30. Since the sample size in this case is only 10, the Normal/Large Sample condition is not met and the conditions for constructing a confidence interval are not met.

Recall that in polar coordinates, the first entry represents the radius, and the second entry of the ordered pair represents the angle:

Now, in Cartesian coordinates, the first entry represents how much you "move" in the x, axis the second entry represents how much you "move" in the y-axis.

Therefore, a point that is the same in both coordinates, can have the same first entry, but we have to be careful with the second entry, from the given options, notice that the point:

x ≈ 95.68 and ac ≈ 52.64.

by using the law of sines

for ac

sin(B)/b = sin(A)/a

sin(20)/ac = sin(70)/46

ac ≈ 52.64

for x

sin(C)/c = sin(B)/b

sin(90)/x = sin(20)/ac

x ≈ 95.68

The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle. At least two angles and their corresponding side measurements should be used at once for the sine law to function.

from the question;

To find the unknown sides, we can utilize the rule of sines and the knowledge that a triangle's angles sum to 180 degrees.

First, let's use the law of sines to find the length of side bc:

sin(A)/a = sin(C)/c

sin(70)/46 = sin(90)/bc

bc = 46*cos(70)

bc ≈ 15.16

Secondly, we may use the fact that a triangle's angles sum to 180 degrees to determine angle b:

angle b = 180 - angle a - angle c

angle b = 180 - 70 - 90

angle b = 20

Now, we can once more determine the length of sides ac and ca using the law of sines:

sin(B)/b = sin(A)/a

sin(20)/ac = sin(70)/46

ac ≈ 52.64

for x

sin(C)/c = sin(B)/b

sin(90)/x = sin(20)/ac

x ≈ 95.68

Therefore, x ≈ 95.68 and ac ≈ 52.64.

Step-by-step explanation:

Edge 2020

the original expression listed in the question can be simplified to -1+tan(2x)/1-tan(2x). expression B can also be simplified to -1+tan(2x)/1-tan(2x)

The expression equivalent to tan(3π/4 -2x) is  -1-tan(2x)/1+(-1)(tan(2x))

It is the trigonometric identity.

Using the trigonometric formula , tan (A-B) = tanA - tanB/ (1+tanA tanB )

tan(3π/4 -2x) = tan(3π/4) - tan2x / 1+ tan(3π/4)tan2x

tan(3π/4 -2x) = -1-tan(2x)/1+(-1)(tan(2x))

Answer:

Step-by-step explanation:

The dimensions that could be the measurements of a similar triangle are; base = 7.8 cm and height = 18 cm

Two triangles are said to be similar provided that they have the same ratio of corresponding sides and an equal pair of corresponding angles.

Now, we are given the side lengths of the triangle as a base length of 3.9 cm and a height of 9 cm.

Thus, this means that a similar triangle will have same ratio of side lengths. Thus;

If new height is h and new base is b, then we have;

9/h = 3.9/b

Thus,

h/b = 9/3.9

If we multiply the right side top and bottom by 2, then we have;

h/b = 18/7.8

18 and 7.8 cm could be similar dimensions.

The height of the trapezoid is h = 4, and the answer is B.

A trapezoid, also known as a trapezium, is a four-sided polygon with two parallel sides, also called the bases. The non-parallel sides are called legs, and they can have different lengths. The parallel sides are perpendicular to the legs.

There are two types of trapezoids:

Isosceles trapezoid: This type of trapezoid has two parallel sides of equal length and two legs of equal length.

Scalene trapezoid: This type of trapezoid has two parallel sides of different lengths and two legs of different lengths.

We can use the formula A = 1/2 * h * (b1 + b2) to solve for h. Substituting the given values, we get:

28 = 1/2 * h * (6 + 8)

28 = 1/2 * h * 14

28 = 7h

h = 4

Therefore, the height of the trapezoid is h = 4, and the answer is B.

Answer:

The slope of the tangent line to the curve at the given point is -11/7.

Step-by-step explanation:

Differentiation is an algebraic process that finds the gradient (slope) of a curve.  At a point, the gradient of a curve is the same as the gradient of the tangent line to the curve at that point.

Given function:

\(4x^2+5xy+y^4=370\)

To differentiate an equation that contains a mixture of x and y terms, use implicit differentiation.

Begin by placing d/dx in front of each term of the equation:

\(\dfrac{\text{d}}{\text{d}x}4x^2+\dfrac{\text{d}}{\text{d}x}5xy+\dfrac{\text{d}}{\text{d}x}y^4=\dfrac{\text{d}}{\text{d}x}370\)

Differentiate the terms in x only (and constant terms):

\(\implies 8x+\dfrac{\text{d}}{\text{d}x}5xy+\dfrac{\text{d}}{\text{d}x}y^4=0\)

Use the chain rule to differentiate terms in y only. In practice, this means differentiate with respect to y, and place dy/dx at the end:

\(\implies 8x+\dfrac{\text{d}}{\text{d}x}5xy+4y^3\dfrac{\text{d}y}{\text{d}x}=0\)

Use the product rule to differentiate terms in both x and y.

\(\boxed{\dfrac{\text{d}}{\text{d}x}u(x)v(y)=u(x)\dfrac{\text{d}}{\text{d}x}v(y)+v(y)\dfrac{\text{d}}{\text{d}x}u(x)}\)

\(\implies 8x+\left(5x\dfrac{\text{d}}{\text{d}x}y+y\dfrac{\text{d}}{\text{d}x}5x\right)+4y^3\dfrac{\text{d}y}{\text{d}x}=0\)

\(\implies 8x+5x\dfrac{\text{d}y}{\text{d}x}+5y+4y^3\dfrac{\text{d}y}{\text{d}x}=0\)

Rearrange the resulting equation in x, y and dy/dx to make dy/dx the subject:

\(\implies 5x\dfrac{\text{d}y}{\text{d}x}+4y^3\dfrac{\text{d}y}{\text{d}x}=-8x-5y\)

\(\implies \dfrac{\text{d}y}{\text{d}x}(5x+4y^3)=-8x-5y\)

\(\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{-8x-5y}{5x+4y^3}\)

To find the slope of the tangent line at the point (-9, -1), substitute x = -9 and y = -1 into the differentiated equation:

\(\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{-8(-9)-5(-1)}{5(-9)+4(-1)^3}\)

\(\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{72+5}{-45-4}\)

\(\implies \dfrac{\text{d}y}{\text{d}x}=-\dfrac{77}{49}\)

\(\implies \dfrac{\text{d}y}{\text{d}x}=-\dfrac{11}{7}\)

Therefore, slope of the tangent line to the curve at the given point is -11/7.
