Answer:

The probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

Step-by-step explanation:

We use the Exponential distribution,

Since we are given that on average, 5 pregnant women with high blood pressure come per week,

So, average = m = 5

Now, on average, 5 people come every week, so,

5 women per week,

so, we get 1 woman per (1/5)th week,

Hence, the mean is m = 1/5 for a woman arriving

and λ = 1/m = 5 = λ

we have to find the probability that it takes higher than a week for a high BP pregnant woman to arrive, i.e,

P(X>1) i.e. the probability that it takes more than a week for a high BP pregnant woman to show up,

Now,

P(X>1) = 1 - P(X<1),

Now, the probability density function is,

\(f(x) = \lambda e^{-\lambda x}\)

And the cumulative distribution function (CDF) is,

\(CDF = 1 - e^{-\lambda x}\)

Now, CDF gives the probability of an event occuring within a given time,

so, for 1 week, we have x = 1, and λ = 5, which gives,

P(X<1) = CDF,

so,

\(P(X < 1)=CDF = 1 - e^{-\lambda x}\\P(X < 1)=1-e^{-5(1)}\\P(X < 1)=1-e^{-5}\\P(X < 1) = 1 - 6.738*10^{-3}\\P(X < 1) = 0.9932\\And,\\P(X > 1) = 1 - 0.9932\\P(X > 1) = 6.8*10^{-3}\\P(X > 1) = 0.0068\)

So, the probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

The option that is not true about polynomial functions is:

Option D. The deg (f ^ 3) = 3m​

For polynomial functions f(x) and g(x), if deg(f) = m * deg(g) = n, then we have the following:

Option A: deg(f + g) = max(m, n)

This is true because we know that the degree of the sum of two polynomials is the maximum of their individual degrees.

Option B: deg(f * g) <= m + n

This is true because we know that the degree of the product of two polynomials is at most the sum of their individual degrees.

Option C: If g is a factor of f, then deg(f) <= m

This is true because If g is a factor of f, it means that f can be divided by g without leaving a remainder. In this case, the degree of f is less than or equal to the degree of g.

D. The deg(f ^ 3) = 3m

This is not true because the degree of the polynomial f raised to the power of 3 is not necessarily equal to 3 times the degree of f. The degree of f^3 will depend on the individual terms and their exponents.

Answer:

I think it -pie/2 but I could be wrong

Answer:

The chosen topic is not meant for use with this type of problem. Try the examples below.

2 = |3x|

−4/5x + 1/25 = 0

3x = 4 − x

Answer

Step-by-step explanation:

This has to be equal to something in order to solve it. I'm going to guess that it is equal to 0

(3x-15)(2x+7) = 0

That means that

3x - 15 = 0

3x = 15

x = 15/3

x = 5

or

2x + 7 = 0

2x = - 7

x = -7/2

x = - 3.5

The only other thing I can think of that this could equal is multiplying the two binomials together.

3x * 2x = 6x^2

3x*7 = 21x

-15*2x = - 30x

-15 * 7 = - 105

6x^2 - 7x - 105

But that does not solve for x.

Answer:

y = -1/3x - 11

Step-by-step explanation:

We need to find our y-intercept. Substitute the coordinate for the x and y in slope-intercept form (y=mx+b). Your x would be 3, and your y would be -12. The equation from that is -12=-1/3(3) + b. Multiply -1/3 and 3. You'll get -12=-1+b. Add the reciprocal of -1 ( positive 1) to -12. You'll get -11=b. Now that you have your b (y-intercept), you can write it in slope-intercept form. y= -1/3x - 11

The probability is 99% that the sample mean amount of soft drink will be between 2.92384 and 3.07616 liters.

What is mean?

In statistics, the mean is a measure of central tendency that represents the average value of a set of numbers. It is calculated by adding up all the values in a dataset and then dividing the sum by the total number of values.

We can use the central limit theorem (CLT) to approximate the distribution of the sample mean, which follows a normal distribution with a mean of the population mean (μ) and a standard deviation of the population standard deviation divided by the square root of the sample size (σ/√n).

Given that the population mean (μ) is 3.0 liters and the population standard deviation (σ) is 0.05 liters, we can compute the standard error of the mean as follows:

standard error of the mean = σ/√n = 0.05/√25 = 0.01 liters

A) To find the probability that the sample mean amount of soft drink will be at least a certain value, we need to convert this value into a z-score using the formula:

z = (x - μ) / (σ / √n)

where x is the sample mean we are interested in.

For a 99% probability, the corresponding z-score is 2.576 (from a standard normal distribution table). Thus, we have:

2.576 = (x - 3.0) / 0.01

Solving for x, we get:

x = 3.02576

Therefore, the probability is 99% that the sample mean amount of soft drink will be at least 3.02576 liters.

B) To find the range of values for the sample mean that contains 99% of the distribution, we can use the same approach as in part A, but for a range of values symmetrically distributed around the mean. Let's call the lower and upper limits of this range x1 and x2, respectively. Then, we have:

2.576 = (x1 - 3.0) / 0.01 and -2.576 = (x2 - 3.0) / 0.01

Solving for x1 and x2, we get:

x1 = 2.92384 and x2 = 3.07616

Therefore, the probability is 99% that the sample mean amount of soft drink will be between 2.92384 and 3.07616 liters.

Step-by-step explanation:

The measure of the angle m∠ZYX of the trapezoid is equal to 139°

A trapezoid is a quadrilateral with two parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The adjacent angles of the trapezium are supplementary, so their sum is equal to 180°.

3x + 19 + x + 1 = 180°

4x + 20 = 180°

4x = 180 - 20 {collect like terms}

4x = 160

x = 160/4 {divide through by 4}

x = 40

m∠ZYX = 3(40) + 19 = 139°.

WXYZ is a trapezoid. Equation used to solve for x is (3x + 19) + (x + 1) = 180° because the angles m∠XYZ and m∠WXY are adjacent angles.

Using the normal distribution, it is found that there is a 0.2798 = 27.98% probability that he’ll use all the toothpaste in the tube.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

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

In this problem:

The probability that he’ll use all the toothpaste in the tube is 1 subtracted by the p-value of Z when X = 0.85, hence:

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

\(Z = \frac{0.85 - 0.78}{0.12}\)

\(Z = 0.583\)

\(Z = 0.583\) has a p-value of 0.7202.

1 - 0.7202 = 0.2798

0.2798 = 27.98% probability that he’ll use all the toothpaste in the tube.

The best assessment of the linearity of the relationship between the day of the month and account balance would be "Because the residual plot has no obvious pattern, and the scatterplot appears linear, it is appropriate to use the line of best fit to predict the account balance based on the day of the month."The correct answer is option C.

When assessing linearity, it is important to examine both the scatterplot and the residual plot. The scatterplot is used to visualize the relationship between the variables, while the residual plot helps us assess the appropriateness of a linear model by examining the pattern of the residuals (the differences between observed and predicted values).

If the scatterplot appears reasonably linear, it suggests that there is a linear relationship between the variables. In this case, since the scatterplot appears linear, it supports the use of a linear model to predict the account balance based on the day of the month.

Furthermore, the residual plot is used to check for any patterns or systematic deviations from the line of best fit. If the residual plot exhibits no obvious pattern and the residuals appear randomly distributed around zero, it indicates that the linear model captures the relationship adequately.

Therefore, if the residual plot shows no obvious pattern, it provides further evidence in favor of using the line of best fit to predict the account balance based on the day of the month.

In conclusion, when the scatterplot appears linear and the residual plot shows no obvious pattern, it is appropriate to use the line of best fit to predict the account balance based on the day of the month.
