A tank contains 5832 litres of water. Each day one-third of the water in the tank is removed and not replaced. How much water remains in the tank at the end of 6 days? [Hint: answer 512 litres] Show me the steps
Answers
Here is your answer.
A tank contains 5832 litres of water.
Total amount of water in tank = 5832 litres.
Each day one-third of the water in the tank is removed and not replaced.
Since one third of the water is removed for six days.
1st day = 1/3rd of 5832 litres is removed
\( = \dfrac{5832}{3} = 1944\)
Amount of water left = 5832 - 1944 = 3888 litres
2nd day = 1/3rd of 3888 litres is removed
\( = \dfrac{3888}{3} = 1296 \)
Amount of water left = 3888 - 1296 = 2592 litres
3rd day = 1/3rd of 2592 litres is removed
\( = \dfrac{2592}{3} = 864 \)
Amount of water left = 2592 - 864 = 1728 litres
4th day = 1/3rd of 1728 litres is removed
\( = \dfrac{1728}{3} = 576 \)
Amount of water left = 1728 - 576 = 1152 litres
5th day = 1/3rrd of 1152 litres is removed
\( = \dfrac{1152}{3} =384 \)
Amount of water left = 1152 - 384 = 768 litres
6th day = 1/3rrd of 768 litres is removed
\( = \dfrac{768}{3} = 256 \)
Amount of water left = 1768 - 256 = 512 litres
So, 512 litres water remains in the tank at the end of 6 days

Find g(x), where g(x) is the translation 2 units left and 4 units down of f(x)=x^2.
Write your answer in the form a(x–h)^2+k, where a, h, and k are integers.
g(x) =
Answers
The function g(x) in the form a(x-h)^2 + k is: \(g(x) = (x + 2)^2 - 4\)
Starting with\(f(x) = x^2\), the translation 2 units left and 4 units down would result in the following transformation:
g(x) = f(x + 2) - 4
Substituting\(f(x) = x^2:\)
\(g(x) = (x + 2)^2 - 4\)
Expanding the square:
\(g(x) = x^2 + 4x + 4 - 4\)
Simplifying:
\(g(x) = x^2 + 4x\)
Now we need to rewrite this expression in the form \(a(x-h)^2 + k.\) To do this, we will complete the square:
\(g(x) = x^2 + 4x\\g(x) = (x^2 + 4x + 4) - 4\\g(x) = (x + 2)^2 - 4\)
Therefore, the function g(x) in the form a(x-h)^2 + k is:
\(g(x) = (x + 2)^2 - 4\)
Where a = 1, h = -2, and k = -4.

For the following event, state whether you think the difference between what occurred and what you would expect by chance is statistically significant. Explain.
An airline with a 95% on-time departure rate has 16 out of 300 flights with late departures.
Answers
The difference between the observed and expected number of late departures is statistically significant, we need to perform a binomial test by calculating the probability of observing 16 or more late departures out of 300 flights assuming the null hypothesis is true. If the resulting p-value is less than 0.05, we can conclude that the difference is statistically significant.
Based on the given information, an airline with a 95% on-time departure rate has 16 out of 300 flights with late departures. The question asks whether the difference between what occurred (16 late departures) and what you would expect by chance is statistically significant.
To determine if the difference is statistically significant, we need to conduct a hypothesis test. In this case, we can use a binomial test since we are dealing with two possible outcomes: on-time departure or late departure.
The null hypothesis (H0) assumes that the observed number of late departures is equal to what would be expected by chance. The alternative hypothesis (Ha) assumes that there is a significant difference between the observed and expected values.
In this case, the expected number of late departures can be calculated by multiplying the total number of flights (300) by the expected on-time departure rate (95%). This gives us an expected value of 300 * 0.05 = 15.
To perform the binomial test, we can calculate the probability of observing 16 or more late departures out of 300 flights, assuming the null hypothesis is true. This probability can be calculated using the binomial probability formula or by using statistical software.
If the resulting probability (also known as the p-value) is less than the significance level (usually 0.05), we can reject the null hypothesis and conclude that the difference between what occurred and what would be expected by chance is statistically significant. Otherwise, if the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that the difference is not statistically significant.

43. MODELING - Tornados The typical number of tornados in the United States in May is 11 more than 14 times the typical number of tornados in December. The sum of the typical number of tornados in December and in May is 341. Determine the typical number of tornados in the month of December anf also in the month of May.
Answers
The number of tornadoes in December and in May are : 22 and 341
How to solve for the tornadoesLet x be the typical number of tornadoes in December.
The typical number of tornados in May is 11 + 14x.
The sum of the typical number of tornados in December and in May is x + (11 + 14x) = 341.
Combining like terms, we get 15x + 11 = 341.
Subtracting 11 from both sides, we get 15x = 330.
Dividing both sides by 15, we get x = 22.
So the typical number of tornados in December is 22, and the typical number of tornadoes in May is 11 + 14x = 11 + 14 * 22 = 341.

1)Angle UZT is congruent to angle b. XZW.

In circle Z, angles that intercept the same arc are congruent. Therefore, to determine which angles are congruent, we need to look at the arcs they intercept.
Angle UZT intercepts minor arc XT, and angle XZW intercepts minor arc XW. Since the measure of arc XT is equal to the measure of arc XW (both are 60 degrees), angle UZT and angle XZW must be congruent.
Angle VZW intercepts minor arc VW, and angle YZX intercepts minor arc YZ. Since the measure of arc VW is equal to the measure of arc YZ (both are 120 degrees), angle VZW and angle YZX must be congruent.

First, let's solve for x.

Subtract 3y from both sides.
\( \sf \: 2x=13-3y \)
Divide both sides by 2.
\( \sf\frac{2x}{2}=\frac{13-3y}{2} \\ \)
Dividing by 2 undoes the multiplication by 2.
\( \boxed{ \boxed{\bf \: x=\frac{13-3y}{2} }}\)
Now, let's solve for y.
\( \sf \: 2 x + 3 y = 13\)
Subtract 2x from both sides.
\( \sf \: 3y=13-2x \)
Divide both sides by 3.
\( \sf \: \frac{3y}{3}=\frac{13-2x}{3} \\ \)
Dividing by 3 undoes the multiplication by 3.

After n years it is
\(A=400\left (1.06\right)^n\)
Sum accumulated is \(\$1200\)
\(\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}\)
