It will take 16hr 30min for Mrs. Smith to catch up.

Let,

t + 3 = Time of Mr. Smith

t = Time of Mrs. Smith

v1 = 55 mph the speed of Mr. Smith

v2 = 65 mph the speed of Mrs. Smith

Formula: Distance = speed × time

v1 ( t + 3)  = v2t

55 ( t + 3 ) = 65t

65t = 55t + 165

65t - 55t = 165

10t = 165

t = 16.5 hr

t = 16 hr 0.5 × 60 min

t = 16 hr 30 min

Therefore, it will take 16hr 30min for Mrs. Smith to catch up.

Answer: A.  2x + 30 = 90

Step-by-step explanation:

You want to choose answer A because you know that together the section of 2x and the section of 30 equal 90 degrees (we know this because the other side shows the right angle which equals 90 degrees).

The equation 2x + 30 = 90 will be used to determine x so option (A) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given an angle with two participants, one is 2x and another one is 30°.

Now if we look right-hand side angle it is a right-angle i.e. 90°.

Since the complete angle above a straight line is 180°

So,

2x + 30 + 90° = 180°

2x + 30 = 90

Hence "The equation 2x + 30 = 90 will be used to determine x".

Simple Random sampling

Meaning:

Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected.

For example, if you randomly select 1000 people from a town with a population of 100,000 residents, each person has a 1000/100000 = 0.01 probability. That's a simple calculation requiring no additional knowledge about the population's composition. Hence, simple random sampling.

Advantage:

Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling.

The value of x from the given triangle is 32√3/3

In order to determine the value of x, first we need to determine the hypotenuse side of the smaller triangle.

sin 60 = 8√2/H

H = 8√2/sin60

H = 8√2 * 2/√3

H = 16√2/√3
H = 16√6/3

For the value of x, we will use the expression

sin45 = (16√6/3)/x

1/√2 = 16√6/3x
3x = 16√12
3x = 32√3

x = 32√3/3

The value of X is 2/3 and -3/2.

According to the statement

we have given equation is 6x^2+5x-6 =0

and we have to find x by the factorization.

Factorization defines the the operation of resolving a quantity into factors.

So, by factorization method the equation is written as

6x^2+5x-6 =0

After forming factors the equation becomes

6x^2+9x-4x-6 =0

3x(2x+3) -2(2x+3) =0

By taking common

(3x-2) (2x+3) = 0

Now equate values equal to 0. and after that the output will get in the form of value of X.

The equation computed shows that the correct options are A, B, and D.

1) The equation we want to rewrite is;

³/₅x + ²/₃ + x = ¹/₂ – ¹/₅x

(³/₅ + 1)x + ²/₃ = ¹/₂ – ¹/₅x

⁸/₅x + ²/₃ = ¹/₂ – ¹/₅x

This corresponds with the solution in Option A

2) ³/₅x + ²/₃ + x = ¹/₂ – ¹/₅x

Let us use multiplication property of equality which states that if we multiply both sides of an equation by the same quantity, then both sides remain equal.

Let's get rid of the denominators by multiplying each term by the LCM of the denominators. LCM of 2,3,5 is 30. Thus;

30(³/₅x) + 30(²/₃) + 30x = 30(¹/₂) - 30(¹/₅x)

Simplifying gives;

18x + 20 + 30x = 15 - 6x

This solution corresponds with that in option B

3) We will make use of additive property of equality which states that when we add the same number to both sides of an equation, then both sides remain equal.

Let's add 6x to both sides of 18x + 20 + 30x = 15 - 6x;

18x + 20 + 30x + 6x = 15 - 6x + 6x

⇒ 24x + 30 + 20 = 15

Using subtractive property of equality, let us subtract 20 from both sides to get;

24x + 30 + 20 - 20 = 15 - 20

This corresponds with the solution in Option D.

[tex]\dfrac{y^2}{9}=1-\dfrac{x^2}{25}[/tex]

Step-by-step explanation:

When converting parametric equations that involve trig functions to Cartesian equations, use trig identities to eliminate the parameter.

Given parametric equations:

[tex]x=5 \sin \theta, \quad y=3 \cos \theta, \quad 0\leq \theta\leq \pi[/tex]

Square the equation for x:

[tex]\implies x^2=(5 \sin \theta)^2=25 \sin^2 \theta[/tex]

Use the identity [tex]\sin^2 x+\cos^2x =1[/tex] to write [tex]x^2[/tex] in terms of cos:

[tex]\implies x^2=25(1-\cos^2 \theta)[/tex]

Isolate [tex]\cos^2 \theta[/tex] :

[tex]\implies \dfrac{x^2}{25}=1-\cos^2 \theta[/tex]

[tex]\implies \cos^2 \theta=1- \dfrac{x^2}{25}[/tex]

Square the equation for y:

[tex]\implies y^2=(3 \cos \theta)^2=9 \cos ^2 \theta[/tex]

Replace [tex]\cos^2 \theta[/tex] with the found equation involving [tex]x^2[/tex] :

[tex]a=-6[/tex]

[tex]\frac{b}{2} =1^{2} -7[/tex]

[tex]\frac{b}{2} =-6[/tex]

[tex]b=-12[/tex]

From the calculations above, we learn that line l and the curve intersect at (2, -6) and (1, -12). Next, we will set up a system of linear equations to solve for the slope and the y-intercept of line l.

[tex]-6=2m+b[/tex]        

[tex]-12=m+b[/tex]

[tex]-24=2m+2b[/tex]

[tex]18=-b[/tex]

[tex]b=-18[/tex]

[tex]-12=m-18[/tex]

[tex]m=6[/tex]

Therefore, the slope of line l is 6.

Answer:

slope = 6

Step-by-step explanation:

substitute the given points into the equation of the curve to find a and b

(2, a )

[tex]\frac{a}{2}[/tex] = 2² - 7 = 4 - 7 = - 3 ( multiply both sides by 2 to clear the fraction )

a = - 6

then point (2, a ) = (2, - 6 )

(1, b )

[tex]\frac{b}{2}[/tex] = 1² - 7 = 1 - 7 = - 6 ( multiply both sides by 2 )

b = - 12

then point (1, b ) = (1, - 12 )

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 6 ) and (x₂, y₂ ) = (1, - 12 )

m = [tex]\frac{-12-(-6)}{1-2}[/tex] = [tex]\frac{-12+6}{-1}[/tex] = [tex]\frac{-6}{-1}[/tex] = 6

The probability that someone does not believe that it is morally wrong to not report all income on tax returns is = 0.15

For given question,

A research center poll showed that 85 percent of people believe that it is morally wrong to not report all income on tax returns.

so, the probability that someone have this belief is P = 0.85

We know that in probability,

p = 1 - q

where;

p is probability of success

q is probability of failure.

Thus the probability that someone does not have this​ belief would be,

= 1 - P

= 1 - 0.85
