What is the equivalent equation solved for h?

Answer:

i think it is the first one

Step-by-step explanation:

A unit rate is a ratio between two different units with a denominator of one. When we divide a fraction's numerator by its denominator, the result is a value in decimal form. Examples include 8 / 4 = 2 and 3 / 6 = 0.5

Answer:

If your were rounding 7.987 to the tenths place, you would get 8.

To round to the tenths place, you are trying to make the number enda tthe tenths place.

You are rounding the 9 in the tenths place, so look at the hundredths place. Since 8 is larger than 5, round the 9 up to 10.

We can't write 7.10 because that is a different number, so add the 1 to the 7 to get 8.

The final answer would be 8.0 or just 8.

A square meets the requirements of a parallelogram.

Answer:

Therefore, a sample that is required to estimate the mean usage of water must be at least 249.

Step-by-step explanation:

We are given that they would like the estimate to have a maximum error of 0.13 gallons.

A previous study found that for an average family the variance is 2.56 gallons and the mean is 16.3 gallons per day.  

As we know that; Margin of error formula is given by;

   Margin of error  =  [tex]Z_(_\frac{\alpha}{2}_) \times \text{Standard of error}[/tex]

where, [tex]\alpha[/tex] = level of significance = 1 - 0.80 = 20% and  [tex](\frac{\alpha}{2} )[/tex] = 10%

Standard of error =  [tex]\frac{\sigma}{\sqrt{n} }[/tex]

where, [tex]\sigma[/tex] = standard deviation = [tex]\sqrt{2.56}[/tex] = 1.6

            n = sample size

Also, the critical value of z at 10% significance level is given in the z table as 1.282.

SO,  Margin of error  =  [tex]Z_(_\frac{\alpha}{2}_) \times \frac{\sigma}{\sqrt{n} }[/tex]

                 0.13           =  [tex]1.282 \times \frac{1.6}{\sqrt{n} }[/tex]

                  [tex]\sqrt{n}[/tex]  =  [tex]\frac{1.282 \times 1.6}{0.13}[/tex]

                    n  =  [tex]15.8^{2}[/tex]

                    n  =  248.95  ≈ 249.

Therefore, a sample that is required to estimate the mean usage of water must be at least 249.

Answer: the answer to this is A

Answer:A

Step-by-step explanation:

Simple. You'll find the function itself as proportional, and not exponential.

The question is incomplete:

The function f(t) represents the cost to connect to the Internet at an online gaming store. It is a function of t, the time in minutes spent on the Internet.  The function f(t) is attached.

Which statement is true about the Internet connection cost?

It costs $5 per hour to connect to the Internet at the gaming store,

The first half hour is free, and then it costs $5 per minute to connect to the Internet,

It costs $10 for each 90 minutes spent connected to the Internet at the gaming store,

Any amount of time over an hour and a half would cost $10,

Answer:

Any amount of time over an hour and a half would cost $10.

Step-by-step explanation:

-It costs $5 per hour to connect to the Internet at the gaming store. False, if you connect between 31 and 90 minutes it costs $5 but it is not a per hour cost.

-The first half hour is free, and then it costs $5 per minute to connect to the Internet. False, the first half hour is free and it costs $5 when you spent connected more than 30 minutes and less or equal 90 minutes.

-It costs $10 for each 90 minutes spent connected to the Internet at the gaming store. False, according to the function 90 minutes cost $5 and if you spend more than 90 minutes, it costs $10.

-Any amount of time over an hour and a half would cost $10. True. An hour and a half is equal to 90 minutes and according to the function, if you spent more than 90 minutes connected, it costs $10.

According to this, the statement that is true about the Internet connection cost is: Any amount of time over an hour and a half would cost $10.

Answer:

a) [tex]a(t)=7e^{\frac{-t}{325} }[/tex]

b) it is noticeable

Step-by-step explanation:

a) Let a(t) be the amount of die at time t. a is in kg and t is in minutes. Therefore:

[tex]\frac{da}{dt} =\frac{-a(t)}{65000}*\frac{200gal}{1 min}=\frac{-a}{325}\\\frac{da}{a} =\frac{-1}{325} dt\\\int\limits{\frac{1}{a} } \, da =\int\limits{\frac{-1}{325} } \, dt\\ln(a)=\frac{-1}{325} t+c\\a=ce^{\frac{-t}{325} }\\at\ t=0, a=7\\ 7=ce^0\\c=7\\a(t)=7e^{\frac{-t}{325} }[/tex]

b) 4 hrs = (4 * 60) min = 240 min

[tex]a(t)=7e^{\frac{-t}{325} }\\a(240)=7e^\frac{-240}{325} = 3.345kg[/tex]

3.345 kg = (3.345 * 1000 / 60000) g/gal = 0.0557 g/gal

0.0557 g/gal > 0.03 g/gal, therefore it is noticeable

Answer:

According to the proble, the total number of goals are 1+11+15+23 = 50: 1 by the goalkeeper, 11 by defense, 15 by midfielders and 23 by strikers.

So, each probability can be found by using standard probabilities

[tex]P=\frac{events}{total outcomes}[/tex]

[tex]P=\frac{11}{50} \approx 0.22[/tex]

Therefore, the defense has a probability of 22% of score that goal.

[tex]P=\frac{15}{50} \approx 0.30[/tex]

Therefore, midfielders have a probability of 30% of scoring that goal.

[tex]P=\frac{23}{50} \approx 0.46[/tex]

Therefore, strikers have a probability of 46% of scoring that goal.

Para resolver correctamente el ejercicio debemos tener en cuenta el numero de casos favorables sobre el numero total de casos posibles; el numero de casos favorables corresponde a la proporción de goles por cada linea,lo que quiere decir que son el numero de goles por cada linea según los datos que da el ejercicio.

El numero total de casos posibles corresponde al valor total de los goles por todo el equipo  (1+11+15+23=50)

Ahora para calcular las probabilidades debemos hacer lo siguiente:

                P=[tex]\frac{11}{50}[/tex] =0.22 ×100=22%; ( la probabilidad de que anoten un gol las defensas es del 22%.

                     P=[tex]\frac{15}{50}[/tex]=0.3 ×100=30% (La probabilidad de que anoten un gol los medios es del 30%

                              P=[tex]\frac{23}{50}[/tex]=0.46×100=46%; (La probabilidad de que anoten un gol los delanteros es del 46%)

Como conclusión podemos decir que hay una mayor probabilidad de que los delanteros puedan anotar ese único gol que les permita ganar el partido pues el numero de casos posibles es mayor comparado con las otras lineas del equipo.

Answer:

a) If the sum of the balls is a factor of 30, eat at Joe's Place. If the sum is not a factor of 30, eat at Taco Towne.

Step-by-step explanation:

The sum table can be represented as :

           1       2      4      7      8

1           X     3       5      8      9

2           3     X       6      9    10

4           5      6      X      11     12

7           8      9       11     X      15

8           9      10      12    15     X

The Probability sum  is a factor of 30 = P(sum is  3, 5, 6, 10, 15)

= [tex]\dfrac{2}{20} +\dfrac{2}{20}+\dfrac{2}{20}+\dfrac{2}{20}+\dfrac{2}{20}[/tex]

= [tex]\dfrac{10}{20}[/tex]

= [tex]\dfrac{1}{2}[/tex]

The Probability sum less than 10 = P(sum is 3,5,8,9,6)

= [tex]\dfrac{2+2+2+4+2}{20}[/tex]

= [tex]\dfrac{3}{5}[/tex]

The probability sum is even = P( sum is 6,8,10, 12)

= [tex]\dfrac{2+2+2+2}{20}[/tex]

= [tex]\dfrac{8}{20}[/tex]

= [tex]\dfrac{2}{5}[/tex]

The probability sum is a multiple of 3 = P( sum is 3,6,9,12,15)

= [tex]\dfrac{12}{20}[/tex]

= [tex]\dfrac{3}{5}[/tex]

since the probability that is the sum of the ball is a factor of 30 is [tex]\dfrac{1}{2}[/tex] , Thus, the probability that the sum is not a factor of 30 will also be [tex]\dfrac{1}{2}[/tex] . Thus; the description that  accurately explains how a fair decision can be made in this situation is option A.

a) If the sum of the balls is a factor of 30, eat at Joe's Place. If the sum is not a factor of 30, eat at Taco Towne.

And replacing we got:

[tex]P(X=3)=(4C3)(0.3)^3 (1-0.3)^{4-3}=0.0756[/tex]

Step-by-step explanation:

Let X the random variable of interest "number of times that we select a blue ball", on this case we now that:

[tex]X \sim Binom(n=4, p=3/10)[/tex]

The probability is always the same since we replace the ball selected in each trial.

The probability mass function for the Binomial distribution is given as:

[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]

Where (nCx) means combinatory and it's given by this formula:

[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]

And we want to find this probability:

[tex] P(X=3)[/tex]

And replacing we got:

[tex]P(X=3)=(4C3)(0.3)^3 (1-0.3)^{4-3}=0.0756[/tex]

Answer:

218

Step-by-step explanation:

456 - 238 =

Borrow 1 from 5 so number is 4 4  16 - 238=

16-8 = 8 in ones' place

4 - 3 = 1 in tens' place

4 - 2 = 2 in hundreds' place

The difference between 456 and 238 is 218.

To regroup and solve the subtraction problem 456 - 238, you can follow these steps:

1. Begin by writing down the two numbers vertically, with the larger number (456) on top and the smaller number (238) below it:

     456

   - 238

2. Start by subtracting the ones (or units) column.

Since 6 is larger than 8, you need to regroup.

Borrow 1 ten from the tens column of 5. This will make the 5 in the tens column become 4, and you add the borrowed ten to the ones column. So, the subtraction becomes 16 - 8, which equals 8:

     456

   - 238

   -------

      8

3. Next, move to the tens column.

Subtract 4 (the regrouped value) from 5, which equals 1:

     456

   - 238

   -------

    1  8

4. Finally, subtract the hundreds column. Subtract 2 from 4, which equals 2:

     456

   - 238

   -------

   2 1  8

Therefore, the difference between 456 and 238 is 218.

Answer:

The sample size required is 2188.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

[tex]CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The margin of error for this interval is:

[tex]MOE= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The information provided is:

X = 162

n = 462

MOE = 0.02

Assume the confidence level as 95%.

Compute the sample proportion as follows:

[tex]\hat p=\frac{X}{n}=\frac{162}{462}=0.351[/tex]

The z-critical value for 95% confidence interval is:

[tex]z_{0.025}=1.96[/tex]

Compute the sample size required as follows:

[tex]MOE= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

      [tex]n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}[/tex]

         [tex]=[\frac{1.96\times\sqrt{0.351(1-0.351)}}{0.02}]^{2}\\\\=2187.781596\\\\\approx 2188[/tex]

Thus, the sample size required is 2188.
