To determine if the bolts vary by more than the required variance, we can conduct a hypothesis test. The null hypothesis (H₀) states that the variance of the bolts is equal to or less than the required variance (σ² ≤ 0.025), while the alternative hypothesis (H₁) states that the variance is greater than the required variance (σ² > 0.025).

Next, we need to determine the critical value(s) of the test statistic. Since we are testing for variance, we will use the chi-square distribution. For a one-tailed test with α = 0.01 and 14 degrees of freedom (n-1), the critical value is 27.488.

Now, we can compare the test statistic to the critical value. The test statistic is calculated as (n-1) * s² / σ², where n is the sample size (15), s² is the sample variance (0.1587²), and σ² is the required variance (0.025).

If the test statistic is greater than the critical value, we reject the null hypothesis and conclude that the bolts vary by more than the required variance. Otherwise, we fail to reject the null hypothesis.

Answer:

  A.  The graph of function g is the graph of function f shifted 6 units up.

Step-by-step explanation:

You want to know how the graph of g(x) = f(x) +6 differs from the graph of f(x).

Adding 6 to the function value will cause the y-coordinate of the point on the graph to be increased by 6. When the y-coordinate is increased, the point moves up.

The graph of g(x) = f(x) +6 is the graph of function f shifted 6 units up, choice A.

Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

The expected value of this gamble is $1.

The expected value of this gamble is the weighted average of all possible outcomes where the weights are the probabilities of each outcome happening.

The formula for expected value (EV) is as follows:

          Expected Value = (Probability of Winning × Amount Won) − (Probability of Losing × Amount Lost)

Hence, substituting the values:

          Expected Value = (0.5 × $10) − (0.5 × $8)

          Expected Value = $5 - $4

          Expected Value = $1

Therefore, the expected value of this gamble is $1.

Answer:

3.5gal/1week

Step-by-step explanation:

First, you would want to find how much the storage container leaks in a day. You can do this by dividing 15 by 30. This answer will tell you how much it leaks in a day.

15 ÷ 13 = 0.5

Now, as you can see 0.5 gallons of water leak out of the container each day.

Next, you will then multiply how much leaks out in a day (0.5) by 7. This will get you your answer of 3.5.

Therefore, 3.5 gallons of water leak out of the container each week.

To check your work you can multiply how much water leaks out in a day by 30.

30*.5 = 15 gallons in 30 days.

The growth factor when water usage is increasing by 7% per year is 1.07. This means that each year, the water usage is multiplied by a factor of 1.07, resulting in a 7% increase from the previous year's usage.

To understand this, let's consider the concept of growth factor. A growth factor represents the multiplier by which a quantity increases or decreases over time. In this case, the water usage is increasing by 7% each year.

When a quantity increases by a certain percentage, we can calculate the growth factor by adding 1 to the percentage (in decimal form). In this case, 7% is equivalent to 0.07 in decimal form. Adding 1 to 0.07 gives us a growth factor of 1.07.

So, each year, the water usage is multiplied by a factor of 1.07, resulting in a 7% increase from the previous year's usage. This growth factor of 1.07 captures the rate of growth in water usage.

Answer:

(0,7)

Step-by-step explanation:

there is no problem work shown.

Answer:

Step-by-step explanation:

In the equation y = mx + b, which is the form Ingrid's equation is in, the m stands for the rate of change. If the water level is decreasing, the rate at which it is decreasing is what goes in for m. The "b" of that equation indicates the starting height of the water, which is 170. The equation should be:

y = -4x + 170, negative because the water is decreasing.

Using the normal distribution, it is found that the replacement time that separates the top 18% from the bottom 82% is of 11.23 years.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem, the mean and the standard deviation are, respectively, given by \(\mu = 9.4, \sigma = 2\).

The desired value is the 82nd percentile, which is X when Z = 0.915, hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(0.915 = \frac{X - 9.4}{2}\)

X - 9.4 = 0.915(2)

X = 11.23

The replacement time that separates the top 18% from the bottom 82% is of 11.23 years.

c = 6

Step-by-step explanation:

-2+7c = 40

=>add 2 to the both sides

7c = 42

=>divide both sides by 7

c = 6

Answer:

c=6

Step-by-step explanation:

-2+7c=40

so if your 2 is negative we want to make it equal 0 so add 2 and we have to do that on the other side of the =

We now have 7c=42

now we want the c to be alone so we do 42/7

Answer:

The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute

Step-by-step explanation:

The given parameters are;

The volume of the prescribed medication to delivered through IV = 800 mL

The duration over which the drug is to be delivered = 8 hours

The rate at which the IV delivers the medication = 30 drips/1 mL

800 mL = 800 × 1 mL

Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips

The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute

The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips

∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute

The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

At the 0.01 significance level, reject the null hypothesis and conclude that women save more than men. we can conclude that there is not enough evidence to support the claim that women save more money than men.

The null hypothesis in this study is that there is no difference in the amount of money saved monthly by single men and women. The alternative hypothesis is that there is a difference in the amount of money saved monthly between single men and women.

To test this hypothesis, we can use a two-sample t-test with equal variances assuming that the population standard deviations are unknown but equal. Using the given data, the t-statistic is calculated to be 1.74.

At the 0.01 significance level with 53 degrees of freedom, the critical value is 2.680. Since the calculated t-statistic of 1.74 is less than the critical value of 2.680, we fail to reject the null hypothesis.

Therefore, we can conclude that there is not enough evidence to support the claim that women save more money than men. At the 0.01 significance level, reject the null hypothesis and conclude that women save more than men.

Para resolver este problema, primero tenemos que multiplicar las fracciones:

3/5 x 4/7 = 12/35

Luego, encontramos cuántas docenas son 12/35 de 420 docenas:

(12/35) x 420 = 144

Así que 3/5 de 4/7 de 420 docenas (que es equivalente a 12/35 de 420 docenas) representa 144 docenas de huevos.

Para encontrar el número total de huevos, multiplicamos 144 docenas por 12 huevos por docena:

144 x 12 = 1,728

Por lo tanto, 3/5 de 4/7 de 420 docenas representa 1,728 huevos.
