The volume of the tank is cubic feet and it will be completely filled with water at the end of minutes.

Answer:

t = 6.8

Explanation:

We know that A is at 1, B is at 10, so that is where we place those two.

First, we need to know what 2/3 of 10 is because the distance between A and B is 10.

Solving 2/3 of 10:

_____________________

- Divide 10 by the denominator, 3

         10 ÷ 3 = 3.3333......

- Multiply 3.3333..... by 2

         3.3333..... x 2 = 6.6666666666667

            or about 6.8 if we round up, which is prefered in these scenarios

Now that we know what 2/3 of 10 is, we can use that number as where to put it on the number line.

So t = 6.8

Hope this helps :)

A graph of triangle A"B"C", the image of ΔABC after a dilation of 2 is shown below.

ΔA"B"C" does not represent a rigid motion because the pre-image and the image are not congruent.

By translating the pre-image triangle ABC vertically down 3 units and horizontally right 1 unit, the coordinates of the image of triangle A'B'C'D' include the following:

(x, y)                               →                  (x + 1, y - 3)

Coordinate A = (2, 3)   →    Coordinate A' = (2 + 1, 3 - 3) = (3, 0)

Coordinate B = (4, 0)   →    Coordinate B' = (4 + 1, 0 - 3) = (5, -3)

Coordinate C = (5, 4)   →     Coordinate C' = (5 + 1, 4 - 3) = (6, 1)

By applying a dilation with a scale factor of 2 centered at the origin, we have:

Coordinate A = (2, 3)   →    Coordinate A" = (4, 6)

Answer:

The probability of guessing the first genre correctly is 1/10. After guessing the first genre, the probability of guessing the second genre correctly is 1/9. Similarly, the probability of guessing the third genre correctly is 1/8. Therefore, the probability of guessing the top 3 genres correctly and in the correct order is:

1/10 * 1/9 * 1/8 = 1/720

So the exact probability is 1/720, which is already reduced to its simplest form.

The probability of observing an income between $70,000 and $90,000 for engineers at this computer company is 0.6217, or about 62.17%.

To solve this problem, we need to standardize the given income range using the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can do this by using the formula:

z = (x - μ) / σ

where x is the income, μ is the mean income, and σ is the standard deviation.

For the lower bound of $70,000, we have:

z₁ = (70,000 - 83,422) / 8,278 = -1.62

For the upper bound of $90,000, we have:

z₂ = (90,000 - 83,422) / 8,278 = 0.79

We can now find the probability of observing an income between $70,000 and $90,000 by calculating the area under the standard normal curve between z₁ and z₂.

We can use a standard normal distribution table or a calculator to find this probability, which turns out to be approximately 0.6217. This means that about 62.17% of engineers at this company earn an income within this range.

The area of the parallelogram can be found using the formula A = base × height:

A = 6 cm × 10 cm

A = 60 cm²

The area of a triangle is given by the formula A = 1/2 × base × height. We know the height is 5 cm and the area is also 60 cm² (since it is equal to the parallelogram). So, we can solve for the base:

60 cm² = 1/2 × base × 5 cm

Dividing both sides by 1/2 × 5 cm gives:

base = 24 cm

Therefore, the base of the triangle is 24 centimeters.

Step-by-step explanation: Initial value = y-intercept

Answer:

We can solve this problem using the following steps:

1. **Calculate the probability of being in each group.**

The probability of being in the binge drinking group is 44%.

The probability of being in the moderate drinking group is 37%.

The probability of being in the abstain group is 9%.

2. **Calculate the probability of being in the accident group.**

The probability of being in the accident group is 17% + 9% = 26%.

3. **Calculate the probability of being in the abstain group and having an accident.**

The probability of being in the abstain group and having an accident is the probability of being in the abstain group multiplied by the probability of having an accident, given that you are in the abstain group.

The probability of being in the abstain group is 9%.

The probability of having an accident, given that you are in the abstain group, is the probability of being in the accident group and being in the abstain group, divided by the probability of being in the abstain group.

The probability of being in the accident group and being in the abstain group is 9%.

The probability of being in the abstain group is 9%.

Therefore, the probability of having an accident, given that you are in the abstain group, is 9% / 9% = 1.

4. **Calculate the probability of having an accident and being in the abstain group.**

The probability of having an accident and being in the abstain group is the probability of being in the abstain group and having an accident.

The probability of being in the abstain group is 9%.

The probability of having an accident, given that you are in the abstain group, is 1.

Therefore, the probability of having an accident and being in the abstain group is 9% * 1 = 9%.

It will take approximately 4 years for the amount in Dillon's bank account to grow to $2,000.

We use the formula for simple interest to solve this problem;

I = P × r × t

where;

I = the interest earned

P = the initial principal (balance) = $1,766

r = the interest rate (as a decimal) = 3.2% = 0.032

t = the time (in years) we need to find

We know that the interest earned is the difference between the final amount (balance + interest) and the initial principal (balance), so we can write;

Interest = Final Amount - Initial Principal

Plugging in the values, we get;

I = $2,000 - $1,766

I = $234

Now we can substitute the values of I, P, and r into the simple interest formula and solve for t;

234 = 1766 × 0.032 × t

Dividing both sides of the equation by (1766 * 0.032) to isolate t:

t = 234 / (1766 × 0.032)

t ≈ 4.19

So, it will take approximately 4.19 years for the amount in Dillon's bank account to grow to $2,000. Since time cannot be in decimal years, we round to the nearest whole year:

t ≈ 4

Therefore, it will take 4 years for the amount in Dillon's bank account to grow to $2,000.

Step-by-step explanation:

The values of the arc length and angles are:

HE = 62

HD = 118

DG = 62

EG = 118

∠DEG + ∠HGE = 62

We have,

The central angle is equal to the intercepted arc length.

So,

62° = HE

And,

∠A = HD

∠A + 62 = 180

∠A = 180 - 62

∠A = 118

HD = 118

And,

DG = ∠M (say)

∠A + 118 = 180

∠M = 180 - 118

∠M = 62

DG = 62

And,

∠A is opposite to ∠N (say)

So,

∠A = ∠N = 118

∠A = EG

EG = 118

And,

From the definition of the exterior angle.

∠DEG + ∠HGE = 62 ______(1)

Also,

The sum of the three angles in AEG = 180

∠EAG + ∠DEG + ∠HGE = 180

∠EAG = 180 - 62 = 118

So,

∠DEG + ∠HGE = 180 - 118

∠DEG + ∠HGE = 62 _______(2)

Thus,

HE = 62

HD = 118

DG = 62

The distribution of the numbers of siblings is best described as skewed to the right so, the median will be a more appropriate measure of the center than the mean

If data is positively skewed - which means that the tail of the distribution leans towards higher values - the median will often be a superior indicator for ascertaining the center than the mean.

This advantage can be attributed to the fact that the median outright ignores extreme values, unlike the median which may become influenced by them and thus pulled towards the extremes of the overall set. Since it is simply the middle value obtained upon sorting the data, its sensitivity to conspicuous outliers is more limited.
