Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of 1/10 gallons per second.

At first I assumed you were asking for 3 different ratios equivalent to 1/10, which could be 2/20, 10/100, or 5/50. But it seems you are asking for ratios equivalent to 1/10 gallons to second. For this, you could change both the 'gallons' and the 'seconds' to get different unit with the same ratio. 1/10 gallon / second * 60 seconds / 1 minute gallons / minute 1/10 gallon / second * 1 gallon / 4 quarts = 1/40 quarts / second combining these two conversions we can do 1/10 gallon / second * 60 second / 1 minute * 1 gallon / 4 quarts = 3/2% 3D

Final answer: 1/10 gallons / second = 6 gallons / minute = 1/40% 3D quarts / second = 3/2 quarts / minute Hope I helped :)

The revenues and expenses of Sentinel Travel Service for the year ended August 31, 2019, follow: Fees earned $745,515 Office exp

kvv77 [185]

Answer:

Step-by-step explanation:

What I will do is attach a picture of the income statement prepared, and explained the process and figures gotten, first we start with writing the Revenue with the year 2019, for the revenue, the only value given is the Fees earned, then after Revenue, we go to expenses, where we have Office, Miscellaneous, and wages, then we find the total of that, then after this we go to net income before Taxes, which is the difference with the total revenue and total expense, which is $745,515 - $544,225 = $201,290

Then we find the income tax expenses and we assume that tax is 40% of your profit, which is 40% of $201,290 = 40/100 x 201290 = $80,516

Then we find the net income which is the income tax expense subtracted from the net income before tax

201290 - 80516 = 120,774

Find the picture attached from the income statement

Independent random samples taken on two university campuses revealed the following information concerning the average amount of

love history [14]

Answer:

$p_v =P(t_{88}>6.960) =2.91x10^{-10}$

So with the p value obtained and using the significance level given $\alpha=0.05$ we have $p_v$ so we can conclude that we have enough evidence to reject the null hypothesis, and we can said that at 5% of significance the mean of the group A is significantly lower than the mean for the group B.

Step-by-step explanation:

The statistic to test the hypothesis is given by this formula:

$t=\frac{(\bar X_A-\bar X_B)-(\mu_{A}-\mu_B)}{\sqrt{\frac{s_A^2}{n_A}}+\frac{s_B^2}{n_B}}$

Where t follows a t distribution with $n_1+n_2 -2$ degrees of freedom

The system of hypothesis on this case are:

Null hypothesis: $\mu_A \leq \mu_B$

Alternative hypothesis: $\mu_A >\mu_B$

Or equivalently:

Null hypothesis: $\mu_A - \mu_B \leq 0$

Alternative hypothesis: $\mu_A -\mu_B>0$

Our notation on this case :

$n_A =50$ represent the sample size for group A

$n_B =40$ represent the sample size for group B

$\bar X_A =280$ represent the sample mean for the group A

$\bar X_B =250$ represent the sample mean for the group B

$s_A=20$ represent the sample standard deviation for group A

$s_B=23$ represent the sample standard deviation for group B

And now we can calculate the statistic:

$t=\frac{(280 -250)-(0)}{\sqrt{\frac{20^2}{50}}+\frac{23^2}{40}}=6.511$

Now we can calculate the degrees of freedom given by:

$df=50+40-2=88$

And now we can calculate the p value using the alternative hypothesis:

$p_v =P(t_{88}>6.960) =2.91x10^{-10}$

Forty-eight percent of all registered voters in a particular state prefer life in prison without parole over the death penalty f

Gennadij [26K]

Answer:

0.63

Step-by-step explanation:

Given that:

$C \ = \ Californians \ (registered \ voters) \ preferrin g \ life \ in \ prison \ without \ parole \ over \ the \ death \\ penalty \ for \ a \ person \ convicted \ of \ first \ degree \ murder.$ P(C) = 0.48

L = Latino Californians

P(L) = 0.364

∴

P(C/L) = 0.63
