Answer:

C

Step-by-step explanation:

Consider f(x) = x^3 and g(x) = (x+1).

Every point is then shifted to the left. Why?

We can plug in some points, let's say x=0.

For f(x), we get 0, for for g(x), we get 1.

Normally, f(x) = 1 when x = 1, but now g(x) = 1 at x = 0. Basically, every point is now shifted left. It's a general rule you have to remember. Sometimes, I used to mix up the plus and minus signs becuase + intuitively for me (at least after doing some physics) is right. But it actually shifts the graph to the left. Just plug in some points and see for yourself. It's honestly the best explanation I can give you at this point in time.

Answer:

m (slope) = 1/2

Step-by-step explanation:

The calculated correlation coefficient (r) is approximately -0.291.

To calculate the correlation coefficient between telomere length and chronicity, we can utilize the given summary data. The correlation coefficient, often denoted as r, measures the strength and direction of the linear relationship between two variables.

Let's denote the sum of products as Σxy, the sum of squares for chronicity as Σx², the sum of squares for telomere length as Σy², and the total sample size as n.

From the given data, we have the following values:

Σxy = -8.822

Σx² = 318.817

Σy² = 2.868

n = 38

The correlation coefficient (r) can be calculated using the following formula:

r = Σxy / √(Σx² * Σy²)

Substituting the given values into the formula:

r = -8.822 / √(318.817 * 2.868)

Now, let's solve this equation step by step:

First, multiply the values inside the square root:

r = -8.822 / √(913.350956)

Next, calculate the square root:

r = -8.822 / 30.219307

Finally, divide Σxy by the square root of the product of Σx² and Σy²:

r ≈ -0.291

Elizabeth's July finance charge will be $9.97. To calculate the finance charge using the previous balance method, we need to consider the average daily balance and the APR (Annual Percentage Rate).

First, we calculate the average daily balance by considering Elizabeth's credit card transactions in July. We sum up the balances on each day and divide by the number of days in the billing cycle:

Average daily balance = (969.26 × 2 + 924.26 × 7 + 996.74 × 2 + 976.74 × 16 + 891.74 × 2) / 29 = $938.07

Next, we calculate the finance charge using the average daily balance and the APR of 14.61%. We multiply the average daily balance by the APR and divide by the number of days in a year:

Finance charge = (938.07 × 0.1461 × 29) / 365 = $9.97

Therefore, Elizabeth's July finance charge will be $9.97.

\(0.7\times10^{-2}\) times as long as the small virus cell is the white blood cell.

Given that, the length of a white blood cell is \(1.4\times10^{-5}\) meter and the length of a small virus cell is \(2.0\times10^{-7}\) meter.

We need to find how many times as long as the small virus cell is the white blood cell.

To determine the power or exponent of 10, let us understand how many places we need to move the decimal point after the single-digit number.

Now, \(\frac{1.4\times10^{-5}}{2.0\times10^{-7}}\)

Step-by-step explanation:

It turns the number positive.

5 fands are equivalent to 7.5 wands.

To determine how many wands are equivalent to 5 fands, we can use the given equivalences and set up a proportion.

We are given:

4 wands = 6 rands

24 rands = 8 fands

First, let's convert the given equivalences to a common unit. Since we want to find the equivalence in wands, we need to convert rands to wands.

From the first equivalence, we can rewrite it as:

1 wand = (6/4) rands

1 wand = (3/2) rands

Now, let's convert rands to fands using the second equivalence:

1 fand = (24/8) rands

1 fand = 3 rands

So, we have:

1 wand = (3/2) rands

1 fand = 3 rands

To find how many wands are equivalent to 5 fands, we set up a proportion:

1 wand / 1 fand = x wands / 5 fands

Cross-multiplying, we get:

x wands = (1 wand / 1 fand) * 5 fands

x wands = (3/2) * 5

x wands = 15/2

x wands = 7.5

(a) P = 32.5 feet

(b) P = 108-2x feet

Step-by-step explanation:

Note: Perimeter is the total distance around the border of a shape.

(a)

P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)

\(27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}\) = 2.25feet

P = 14'+2.25'+14'+2.25'

P = 32.5' = 32.5 feet

(b)

P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.

P = 108' -2x'

P = 108-2x feet

The wave which represents this harmonic is C. third harmonic represents this wave.

The given length of wire is 62.0 cm, and it is vibrating to form a standing wave with three antinodes. The wire is fixed at both ends. Our task is to determine which harmonic this wave represents.

To find the harmonic, we can use the formula 2L = (nλ), where L represents the length of the wire, n is the number of antinodes, and λ is the wavelength of the wave.

By substituting the given values into the formula, we have:

2L = (nλ)

2 * 62.0 cm = (3 * λ)

124.0 cm = 3λ

Dividing both sides by 3, we get:

41.33 cm = λ

From this calculation, we can conclude that the wavelength of the wave is 41.33 cm.

Now, let's determine the harmonic. The harmonic number is equal to the number of antinodes, which in this case is three. Therefore, the wave represents the third harmonic.

In conclusion, the correct option is (c) third harmonic.

The 95% confidence interval for the true proportion of all auto accidents involving teenage drivers is approximately (0.1205, 0.1927).

To find the 95% confidence interval for the true proportion of all auto accidents involving teenage drivers, we can use the formula for the confidence interval for a proportion.

The formula for the confidence interval is:

CI = p1 ± Z * √((p1 * (1 - p1)) / n)

Where:

CI is the confidence interval,

p1 is the sample proportion (proportion of accidents involving teenage drivers),

Z is the Z-score corresponding to the desired confidence level (95% confidence level corresponds to Z ≈ 1.96),

n is the sample size (number of accidents checked).

Given:

Number of accidents checked (sample size), n = 582

Number of accidents involving teenage drivers, x = 91

First, we calculate the sample proportion:

p1 = x / n = 91 / 582 ≈ 0.1566

Now we can calculate the confidence interval:

CI = 0.1566 ± 1.96 * √((0.1566 * (1 - 0.1566)) / 582)

Calculating the standard error of the proportion:

SE = √((p1 * (1 - p1)) / n) = √((0.1566 * (1 - 0.1566)) / 582) ≈ 0.0184

Substituting the values into the formula:

CI = 0.1566 ± 1.96 * 0.0184

Calculating the values:

CI = 0.1566 ± 0.0361

Finally, we can simplify the confidence interval:

CI = (0.1205, 0.1927)

Therefore, the 95% confidence interval for the true proportion of all auto accidents involving teenage drivers is approximately (0.1205, 0.1927).
