A list of numbers is made with the pattern: Start with 3, and multiply by 2 each time.
Here is the beginning of the list of numbers: 3, 6, 12, . . .
Explain how you could use "fill down" in a spreadsheet to find the tenth number in this list.

To create a frequency distribution using the "2 to the power of k rule", we need to determine the value of k. The rule states that k should be equal to the largest value in the dataset. In this case, the largest value is 65.

Next, we calculate 2 to the power of k, which is 2^k. Since k = 6 (since 2^6 = 64), we have 2^6 = 64.

Now, we can create the frequency distribution. We start by dividing the range of the data (65 - 4 = 61) by 64 (2^k) to determine the interval size.

61 / 64 = 0.953125

Since the interval size is less than 1, we round it up to 1.

Now, we can start creating the frequency distribution table. We'll start with the lower limit of the first interval, which is 4. Then, we add the interval size to get the upper limit of the first interval, which is 4 + 1 = 5.

Now, we count how many values fall within this interval. From the given data, we have 4 values (4, 18, 19, 24). So, the frequency for this interval is 4.

We continue this process for the rest of the intervals until we reach the largest value in the data.

Here's the frequency distribution table:

Interval   Frequency
4-5           4
6-7           2
8-9           2
10-11       0
12-13       0
14-15       0
16-17       0
18-19       2
20-21       0
22-23       1
24-25       2
26-27       1
28-29       0
30-31       0
32-33       0
34-35       2
36-37       1
38-39       2
40-41       1
42-43       2
44-45       1
46-47       0
48-49       1
50-51       3
52-53       1
54-55       3
56-57       1
58-59       0
60-61       1
62-63       1
64-65       1

In conclusion, we used the "2 to the power of k rule" to create a frequency distribution for the number of families who used the tri-c day care service during a 30-day period. The frequency distribution table shows the intervals and the corresponding frequency of values falling within each interval.

Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.

Here are the steps on how to calculate the amount Henry invested:

Convert the annual interest rate to a monthly rate.

\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)

Calculate the number of years.

\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)

Use the compound interest formula to calculate the amount Henry invested.

\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)

where:

FV is the future value ($75,000)

PV is the present value (unknown)

r is the interest rate (0.375%)

t is the number of years (1.5 years)

\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)

\$75,000 = PV * 1.0297

\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)

PV = \$72,831.68

Therefore, Henry invested \$72,831.68 in the savings account.

The entrance fees is 13 dollars charges by the paintball court.

Let us assume that the entrance fees is $X and the actual cost of using one ball is $Y charged by the paintball court.

According to one situation,

Total cost of using to ball = Cost of entry fees + actual cost of using two ball.

So, we can write,

X + 2Y = 18

Let us say that this is our equation 1,

Also, it is provided,

Total cost of using 4 balls = cost of entry fees + actual cost of using four balls.

X + 4Y = 23

Let us say that this is our equation 2,

Both of our equations are linear equations with two variables,

Now, substracting equation 1 from equation 2,

X + 4Y -(X + 2Y) = 23 - 18

2Y = 5

Y = $2.5.

Putting the value of Y = 2.5 in equation 1,

X + 2(2.5) = 18

X = 18 - 5

X = $13.

So, the entry fees is 13 dollars.

The scientist claims that 60% of U.S. adults believe humans contribute to an increase in global temperature. A 95% confidence interval for the proportion of U.S. adults who hold this belief is found to be (0.626, 0.674). This confidence interval supports the scientist's claim.

To determine if this confidence interval supports the scientist's claim, we need to examine whether the claimed proportion of 60% falls within the confidence interval.

The confidence interval (0.626, 0.674) indicates that we are 95% confident that the true proportion of U.S. adults who believe humans contribute to an increase in global temperature lies between 0.626 and 0.674. Since the claimed proportion of 60% falls within this range, it is within the confidence interval.

Therefore, we can conclude that the confidence interval supports the scientist's claim. This means there is strong evidence to suggest that a significant majority of U.S. adults believe humans contribute to an increase in global temperature, as the lower bound of the confidence interval is 62.6% and the upper bound is 67.4%.

The sampling technique used in this scenario is simple random sampling.

Simple random sampling involves randomly selecting a subset of elements from a population in such a way that every element has an equal chance of being chosen.

In this case, the gardener randomly chose 2 plants from a total of 20 plants. By randomly selecting the plants, the gardener ensured that each plant had an equal probability of being included in the sample.

Simple random sampling is a common and straightforward technique used to obtain a representative sample from a larger population. It helps minimize bias and allows for generalization of the findings from the sample to the entire population.

By inspecting the randomly selected plants, the gardener can make inferences about the development of the tomato plants as a whole, assuming that the selected plants are representative of the entire population of tomato plants.

Therefore, the gardener utilized a simple random sampling technique by randomly selecting and inspecting two out of twenty tomato plants to assess their development.

This set is closed under scalar multiplications. Statement 1 is false.

This set is a subspace. This statement is also false because this set does not contain a zero vector so it is not a subspace.

This set is closed under vector addition. This is false. Because let v and w be two vectors such that v=(v1,v2); w=(w1,w2).

The set contains the zero vector. Statement 4 is false because the sum of two zero vectors cannot be equal to 1.

Since v and w are vectors satisfying the condition of space so v1+v2=1;w1+w2=1

Now we check whether v+w also belongs to the same space or not.

v+w=(v1,v2)+(w1,w2)=(v1+w1, v2+w2)

We shall check whether components of v+w also add up to 1.

v1+w1+v2+w2=v1+v2+w1+w2=1+1=2

So it means that this space is not closed under addition too.

Consider a vector v=(v1,v2) from the space.

Obviously v1+v2=1

Now let us take a constant 'c'  and consider the behavior of

cv=c(v1,v2)=(cv1,cv2)

Now we check whether components of this vector add up to 1.

cv1+cv2=c(v1+v2)=c\neq 1

The measure of the arc 13cm long with a radius = 1  is 13rad

The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.

Length of an arc = ∅/360 x 2πr

where ∅ = subtended angle in degree

r = 1 = radius of the complete circle

length = 13

13 =  ∅ /360 x  2 x π x 1

but 2π rad = 360  degrees

substitute  2π rad  for 360 into the equation

13 =  ∅/2π rad  x 2 x π x 1

By cross multiplying

∅ = 13 x 2π rad / 2 x π

∅ = 13 rad

In conclusion, the angle subtended by the arc in radians is 13 rad.

Jon's savings before he gave Rick the gift was $600.  An equation to represent this situation: 400 + (1/8)x = 475

To determine Jon's savings before he gave Rick the gift, we can use an equation. Let's represent Jon's savings with the variable x.

According to the problem, Jon gave Rick 1/8 of his savings, which is equal to (1/8)x. We also know that Rick originally had $400 and after receiving the gift, he had $475. So we can write an equation to represent this situation:
400 + (1/8)x = 475

Now, we can solve for x to find out Jon's savings before he gave Rick the gift. First, let's isolate the variable on one side of the equation:
(1/8)x = 475 - 400
(1/8)x = 75

Next, we can multiply both sides of the equation by 8 to get rid of the fraction:
x = 75 * 8
x = 600

So, Jon's savings before he gave Rick the gift was $600.
