The percentage error is 11.1%

Percentage error is simply the difference between the exact and the estimated values as a percentage

The given parameters are:

The percentage error is then calculated as:

[tex]\% E = \frac{50 - 45}{45} \times 100\%[/tex]

Evaluate the difference

[tex]\% E = \frac{5}{45} \times 100\%[/tex]

So, we have:

[tex]\% E = \frac{500}{45} \%[/tex]

[tex]\% E = 11.1\%[/tex]

Hence, the percentage error is 11.1%

Answer:

B) A person runs x miles at a rate of 12 minutes per miles then walks for 10 minutes is your best answer.

Step-by-step explanation:

This is the only one that meets all requirements, though the wording is rather poor, in my opinion.

'x" is stated in this statement rather correctly compared to the others.

For A), "A person drives 12 miles each day (x) for 10 days:

x would signify the amount of days: 12x or 12(10) = 120

For C), " A person drives 12 miles plus 10 miles for each additional hour they drive":

x would signify the amount of hour: 10x + 12

For D), "A person runs 12 miles the first day, x miles the second day, and 10 miles the third day":

x would signify the stand-alone value: 12 + x + 10

Answer:

Step-by-step explanation:

A transversal is a line that is intersecting at 2 points. Let's verify all options to see which one is the odd one out.

Option A

This line is a transversal to AC because it is intersecting in between AC. Hence, Option A is incorrect for this question.

Option B

This line is also a transversal to AC because it is intersecting in between AC. Hence, Option B is incorrect for this question.

Option C

This line is not a transversal because it is not intersecting AC. Hence, this will be the correct answer for this question.

Option D

This line is a transversal because it is intersecting in between AC. Hence, Option D is incorrect for this question.

After verifying all options, Option C is the most reasonable option. Hence, Option C is correct.

Linear equation are the equation which has the highest power of the unknown variable is 1.The expressions given in the  option 1, 2, and 3 are equivalent to [tex]7x - 14[/tex].

The equations given in the problem are the linear equations.

Linear equation are the equation which has the highest power of the unknown variable is 1.

Given-

1) The given expression in the problem is,

[tex]f(x)=7x-14[/tex]

Rewrite the equation as,

[tex]f(x)=(7x-14)[/tex]

Take out the negative sign from the bracket,

[tex]f(x)=-(-7x+14)[/tex]

Rewrite the equation with positive terms first.

[tex]f(x)=-(14-7x)[/tex]

Hence the given equation is equivalent to the option 1.

2) The given equation,

[tex]f(x)=7x-14[/tex]

On solving further take out the 7 common from the bracket,

[tex]f(x)=7(x-2)[/tex]

Thus the given equation is equivalent to the option 2.

3) The given equation,

[tex]f(x)=7x-14[/tex]

Split the term of x,

[tex]f(x)=4x+3x-14[/tex]

Rewrite the equation,

[tex]f(x)=3x-14+4x[/tex]

Hence the given equation is equivalent to the option 3.

4) The given equation,

[tex]f(x)=7x-14[/tex]

Split the term of x and constant term,

[tex]f(x)=5x+2x-10-4[/tex]

Rewrite the equation,

[tex]f(x)=2x-10+5x-4[/tex]

Hence the given equation is not equivalent to the option 4.

Thus the expressions given in the  option 1, 2, and 3 are equivalent to [tex]7x - 14[/tex].

Being male and preferring brand A are independent.

Because: if independent then P(male and brand A) = P(male) P(brand A) = 0.48 * 0.75 = 0.36 and that is true (= value in the table)

Answer:

Figure out the x and y intercepts.

Step-by-step explanation:

you should find what the y or x intercept's are.

To figure that out you need to divide the number next to x or y to 8. use x to find out x intercept and y for y intercept.

lets find out y intercept

8 / -2 = -4

and now x intercept

8 / 3 = 1.75 or 1 (3/4)

Once you found out the intercepts you can now graph the equation.

One short cut to remember how the solution is found, remember that degree unit must be removed and radian has to come(to convert from degree to radian) and that will be removed only when division by degree will happen and multiplication by something in radian.

The correct expression that converts 45° to radian is given by:
Option C:  [tex]45^\circ \times \dfrac{\pi^c}{180^\circ}[/tex]

Both measure angles. Remember the fact that one full rotation is 360° or [tex]2\pi^c[/tex] (this superscript c denotes that angle is in radians).

pi is 3.14159... and pi radians means 3.14.. radians which measures half of full rotation(since 2 times pi measures full rotation).

Thus, we have:

[tex]360^\circ = 2\pi^c\\\\ \text{Dividing by 360 on both sides}\\\\ 1^\circ = \dfrac{2\pi^c}{360}\\\\ 1^\circ = \dfrac{\pi^c}{180}[/tex]

Thus, we have:

[tex]45^\circ = 45 \times 1^\circ = 45 \dfrac{\pi^c}{180} = \dfrac{45^\circ\pi^c}{180^\circ}\\ [/tex]

Thus, the correct expression that converts 45° to radian is given by:
Option C:  [tex]45^\circ \times \dfrac{\pi^c}{180^\circ}[/tex]

Step-by-step explanation:

Pic is blurry but just set the expressions equation to each other and solve. All sides are the same length.

Answer:

D)  BC = 30

Step-by-step explanation:

this is an equilateral triangle, meaning all sides have the same value

therefore it is mathematically correct to write this equation:

4x + 2 = 5x - 5

subtract 2 from each side to get:

4x = 5x - 7

subtract '5x' from each side to get:

-x = -7

divide or multiply each side by -1 to get:

x = 7

Substitute 7 in for 'x' in the expression: 4x + 2 to solve for BC:

4(7)+2 = 30

Check that 'x' = 7:

4(7)+2 should equal 5(7)-5

28+2 = 35-5

30 = 30

According to the directions, the location I am at is 65o N, 75o E.

To know our location we must take into account the information we have, which is:

According to the above, the easiest thing to know is the longitudinal location with respect to the Greenwich meridian, so if we are 5 hours ahead of the reference time we can establish that we are at 75° E.

On the other hand, taking the polar star as a reference, the latitudinal location can be established. Keep in mind that the polar star is only visible in the northern hemisphere, so we would be in this hemisphere.

On the other hand, the way to know how far north we are is by calculating the degrees between the horizon and the star, that will tell us what latitudinal location we are at. So if the star is at 65°, we may be close to 65° north latitude.

Answer:

(n - 3)(2)  or  2(n - 3)

Step-by-step explanation:

The area of a rectangle is its length multiplied by its width.  But which side is length is up to you; there are 2 choices!

If the side marked n - 3 is the length, then the side marked 2 is the width.  the area is (n - 3)(2).

On the other hand, if the side marked 2 is the length, then the side marked n - 3 is the width.  The area is 2(n - 3).

By the way, both those expressions are equivalent to 2n - 6.

Answer:

After 1 second, the ball will reach a maximum height of 16 feet

Step-by-step explanation:

The height of the ball after t seconds: h(t) = -16t^2 + 32t

The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola

t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second

then

h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16

After 1 second, the ball will reach a maximum height of 16 feet

Buy 14 cupcakes

Step-by-step explanation:

4 - 9 - x

the pattern is plus 5

9+5=x

x=14

The required number of the cups next in the series is given as 14, the required series is given as 4, 9, 14, and so on.

Given that,
Two weeks ago, bought 4 cupcakes last week, and bought 9, a series to be determined.

A Series is defined as a group of numbers related or nonrelated to each other

Here,
According to the question,
2 weeks ago Number of cupcakes was 4,
1 week ago the number of cupcakes was 9.
The relationship formed can be given as y = --5x + 14,
put x = 0 we would get the number that comes next in the series,
So,
y = -5(0) + 14
y = 14

Thus, the required number of the cups next in the series is given as 14, the required series is given as 4, 9, 14, and so on.
