The possible amount of time is 90 seconds that it takes you to run around the baseball field

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

The options are missing.

The options are:

We have a radius of the circle is:

r = 150 ft

The perimeter of the circle = 2πr = 2π(150) = 300π ft

The running path distance = 40% of the perimeter of the circle

= 40% of 300π

= 120π ft

Assume the tape length is 50 m

Total distance = 200 + 200 + 120π - 50 = 726.99

The rate is 8 feet per second.

Time = distance/rate = 726.99/8 = 90.87 ≈ 90 seconds

Thus, the possible amount of time is 90 seconds that it takes you to run around the baseball field

The price of an adult ticket is 12$.

And the price of a student ticket is 9$.

Let ‘x’ be the price of an adult ticket.

Let ‘y’ be the price of a student ticket.

On the first day of ticket sales, the school sold 14 adult tickets and 3 student tickets for a total of $195 i.e

14x + 3y = 195$    i)

15x + 14y = 306$   ii)

from equation i) we get the value of y,

y = (195 - 14x)/3

put this value of y in equation ii) we get,

= 15x +14{(195 - 14x)/3} = 306

= (45x +2730 - 196x)/3 = 306

= (45x +2730 - 196x) = 918

= -151x = -1812

= x =12$

then value of y we get ,

put value of x in y,

y = (195 - 14*12)/3

= 27/3

= 9$

hence, the price of an adult ticket is 12$.

Answer: x = 8

Step-by-step explanation:

Hello again XD.

This is a coordinate plane and all the angles on a coordinate plane add up to 360°

Divide 360 by 4 to get the measurement of the section we are working in.

360/4 = 90°

This means it is complementary and complementary angles state that both separate angles added together = 90°

therefore,

6x + 2 + 40 = 90

combine like terms:

6x + 42 = 90

now subtract 42 from both sides

6x = 48

divide 6 from both sides to get:

x = 8

The percentage of households in the town with internet access is estimates as 47.8%, give or take 2.2% or so.

According to statement we have given

239 of the 500 households in the sample had internet access.

So, find sample percentage then

Sample percentage= 500/239 =0.478=47.8%

Thus we estimate the percentage as 47.8%.

The box contains 25,000 tickets of which 47.8% are 1's and the remaining 52.2% tickets are 0's. We will draw 500 tickets from the box.

Number of draws=500

Now, find the SD then

[tex]SD= (Big number - Small number) * \sqrt{Fraction with big number * fraction with small number}[/tex]

Substitute the values then

[tex]SD= (1 - 0) * \sqrt{0.478 *0.522}[/tex]

[tex]SD=0.4995[/tex]

Now find the standard error of sum then

The standard error of the sum is the product of the square root of the number of draws and the standard deviation of the box.

[tex]SE sum =\sqrt{Number of draws} * SD box[/tex]

[tex]SE sum =\sqrt{500} * 0.4995[/tex]

[tex]SE sum =11.16[/tex]

Now find the standard error of percentage then

The standard error of the percentage is the standard error for the sum divided by the sample size.

SE percentage= SE for number/Number of draws ×100%

= 50011.1692×100%

≈0.022×100%

=2.2%

Thus the percentage of households in the town with internet access is estimates as 47.8%, give or take 2.2% or so.

Using the normal distribution, it is found that there is a 0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters are given as follows:

[tex]\mu = 42.05, \sigma = 0.025, n = 25, s = \frac{0.025}{\sqrt{25}} = 0.005[/tex]

The probability that the mean weight of 25 pods of coffee is less than 42.035 grams is the p-value of Z when X = 42.035, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42.035 - 42.05}{0.005}[/tex]

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

Answer:

6x+6x2+3

Step-by-step explanation:

6x2+5x+1+x+2

Combine 5x and x to get 6x.

6x2+6x+1+2

Add 1 and 2 to get 3.

6x2+6x+3

The simplified form of the expression (6x² + 5x + 1) + (x + 2) is 6x^2 + 6x + 3.

To solve the expression (6x² + 5x + 1) + (x + 2)

we need to combine like terms.

First, let's remove the parentheses:

6x² + 5x + 1 + x + 2

Next, we combine like terms:

6x² + (5x + x) + (1 + 2)

Simplifying further:

6x^2 + 6x + 3

Therefore, the simplified form of (6x² + 5x + 1) + (x + 2) is 6x² + 6x + 3.

Answer:

x = 8

Step-by-step explanation:

Because they are alternate exterior angles, the two angles must equal to each other. You can set up the equation:

9x-2 = 8x + 6

And then solve for x.

9x - 2 = 8x + 6

9x - 8x = 6 + 2

x = 6 + 2

x = 8

The sum of measures of angles A and B is 90°

Hence the angles are complementary

Answer:

4/10

Step-by-step explanation:

If A and B are independent events, P(A∩B) = P(A).P(B)
Therefore, P(B) = P(A∩B) /P(A)

P(A∩B)  = 1/5, P(A) = 1/2

P(B) = 1/5 ÷ 1/2 = 1 /5 * 2/1 = 2/5 which is 4/10 if you multiply numerator and denominator by 2
