Answer:

0.259

Step-by-step explanation:

There are some rules in determining what numbers are significant figures.

We can determine how many significant figures the number currently has.

There are currently seven significant figures. In order to round the number to three significant figures, we must round it to the thousandths place, or the 9.

The rounding rules are:

Since 0 is less than 5, the number rounded to 3 significant figures is 0.259.

Answer- 9 shelves

In order to find out how many shelves are need we must divided 175 into 20. 175 divided by 20 is 8.75. But, because you cannot have have .75 of a shelf, you have to round this to a whole. This means that 9 shelves will be the least needed number of shelves need to store 175 books. To check this answer 20 books X 8 shelves is 160 books, which means eight shelves can only store 160 books, we will need and additional shelf to store the last 15 books.

The dependent variable in this research study is the amount of money spent on athletic apparel.

The dependent variable is the variable that is measured or observed in response to changes in the independent variable. In this case, the researcher is interested in comparing different groups of people (college athletes, recreational athletes, people who used to be athletes but are not anymore, and non-athletes) and examining how their spending on athletic apparel varies. The amount of money spent on athletic apparel is the variable that will be measured and compared across the different groups.

By analyzing and comparing the spending patterns of these groups, the researcher aims to determine if there are any significant differences in how much money each group spends on athletic apparel. The dependent variable, in this case, serves as an indicator or measure of the behavior or preference being studied.

b. convergent Since the limit approaches infinity, the integral diverges. Therefore, the answer is convergent .

To determine the convergence of the integral [infinity] 39 ln(x) x dx, we can use the integral test. This test states that if f(x) is a continuous, positive, and decreasing function on [a, infinity), then the improper integral [a, infinity) f(x) dx converges if and only if the series sum from n=a to infinity of f(n) converges.

In this case, we have f(x) = 39 ln(x)/x, which is a continuous, positive, and decreasing function on [1, infinity). Thus, we can apply the integral test.

Let's evaluate the integral using integration by parts:

∫ 39 ln(x)/x dx = 39 ∫ ln(x) d(ln(x))
= 39 (ln(x))^2/2 + C

Now, we need to check whether the integral converges or diverges.

As x approaches infinity, ln(x) grows without bound, so (ln(x))^2 grows even faster. Thus, the integral is improper at infinity.

We can evaluate the limit as x approaches infinity of (ln(x))^2/2 to determine whether the integral converges or diverges:

lim (x → infinity) (ln(x))^2/2 = infinity

Step-by-step explanation:

Answer:The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.

Cost of 1 pound if sliced ham = $4

Step-by-step explanation:

Mrs. Ruiz bought 4 1/4 pounds of sliced ham for $17. At that rate, what is the cost of 1 pound of sliced ham?

Total pounds of ham bought= 4 1/4 pounds

Total cost = $17

what is the cost of 1 pound of sliced ham

Cost of 1 pound if sliced ham = Total cost of 4 1/4 sliced ham / 4 1/4

= $17 ÷ 17/4

= 17 × 4/17

= 4

Note:4 1/4 = 17/4

Cost of 1 pound if sliced ham = $4

Check:

4 1/4 pounds × $4 per pound

= 17/4 × 4

= $17

The way we can do a translation and a rotation to be used to map ΔHJK to ΔLMN is:

Option C: translate K to N and rotate about K until HK lies on the line containing LN.

There are different types of transformation such as:

Translation

Rotation

Reflection

Dilation

We want to find how a translation and a rotation be used to map ΔHJK to ΔLMN.

This is the concept of the transformation, ΔHJK=ΔLMN, from the diagram:

∠H=∠L

∠K=∠N

∠M=∠J

In order to map ΔHJK to ΔLMN, we need to translate K to N and rotate about K until HK lies on the same line containing LN.

Answer: y = -3x - 4

Step-by-step explanation:

Slope intercept form would be y = mx + b. To get your equation to this form you would need to isolate for y as shown:

3x + y = -4

y = -3x - 4 <-- Here I subtracted both sides by 3x

The function that is likely the best fit is given as follows:

Logarithmic regression.

The function of a best fit is a logarithmic regression, as the function starts with a fast increasing rate until it approaches the vertical asymptote.

Since it's a two-tailed test, P-value = 2 * 0.1271 ≈ 0.2542.

With α = 0.01, the P-value (0.2542) is greater than α, so Steve should fail to reject the null hypothesis.

Steve's hypotheses should be:

H₀: p = 0.346

H₁: p ≠ 0.346

Using the sample, we find the sample proportion (p_hat) is 93/250 = 0.372.

To calculate the z-test statistic:

z = (p_hat - p) / sqrt((p * (1 - p)) / n)

z = (0.372 - 0.346) / sqrt((0.346 * 0.654) / 250)

z ≈ 1.14

To find the P-value, use a two-tailed test and a z-table to determine the area right of z. ≈ 0.1271. Since it's a two-tailed test, P-value = 2 * 0.1271 ≈ 0.2542.

With α = 0.01, the P-value (0.2542) is greater than α, so Steve should fail to reject the null hypothesis.

Answer:

Step-by-step explanation:

1.54/28=0.055

Step-by-step explanation:

Starting with the equation x^2 + y^2 = 25, we can implicitly differentiate with respect to t using the chain rule:

2x dx/dt + 2y dy/dt = 0

Now we can plug in the given values for dy/dt, x, and y:

2(3) dx/dt + 2(4) (3) = 0

Simplifying:

6 dx/dt + 24 = 0

Subtracting 24 from both sides:

6 dx/dt = -24

Dividing by 6:

dx/dt = -4

Therefore, dx/dt = -4 when dy/dt = 3, x = 3, and y = 4.

PS I love you. And i asked the Ask AI app to write this for me. Get it for free --> https://get-askai.app

The value of the derivative, dx/dt is -4, when x^2 + y^2 = 25, dy/dt = 3, x = 3, and y = 4.

1. Differentiate both sides of the equation x^2 + y^2 = 25 with respect to t. Use the chain rule for differentiating y^2 with respect to t.
  d(x^2)/dt + d(y^2)/dt = d(25)/dt

2. Apply the chain rule,
  2x(dx/dt) + 2y(dy/dt) = 0

3. Plug in the given values for x, y, and dy/dt,
  2(3)(dx/dt) + 2(4)(3) = 0

4. Simplifying the equation,
  6(dx/dt) + 24 = 0

5. Solve for dx/dt,
  6(dx/dt) = -24
  dx/dt = -24/6
  dx/dt = -4

So, when x^2 + y^2 = 25, dy/dt = 3, x = 3, and y = 4, the value of the derivative, dx/dt is -4.
