The probability distribution at each point x along the horizontal axis.

For a Normal distribution with mean 0 and standard deviation 1,

the following Python line outputs the probability p(-0.15 < x < 1.88):

print(st.norm.cdf(1.88, 0, 1) - st.norm.cdf(-0.15, 0, 1))

Probability is the likelihood or chance that an event will occur. It is a number between 0 and 1, with 0 indicating that an event will never occur and 1 indicating that an event will always occur.

Probability values range from 0 to 1, with a value of 0 indicating that the event will never occur and a value of 1 indicating that the event will always occur.

The probability is the value between 0 and 1 that indicates the likelihood of an event occurring. The probability is obtained by dividing the number of ways an event can occur by the total number of possible outcomes.

Scipy.stats.norm is the normal distribution's probability density function (pdf) in SciPy.

Therefore, if Randa cleanses plates five times, she will use 2 1/2 gallons more than 20 gallons of water.

In the US, the gallon is a measurement unit for substances like milk, fuel, and water. If the petrol in your vehicle is nearly depleted, you should stop and get at least a couple extra gallons. A gallon is equal to 4 pints, or 3.785 gallons, of liquid.

To find out how many gallons of water Randa will use if she washes dishes five times, we need to multiply the amount of water she uses each time by the number of times she washes dishes:

4 1/2 gallons per wash x 5 washes = 22 1/2 gallons

Therefore, Randa will use 22 1/2 gallons of water if she washes dishes five times.

To find out how much more than 20 gallons of water she will use, we need to subtract 20 from the total amount of water she will use:

22 1/2 gallons - 20 gallons = 2 1/2 gallons

I think 16 vials are needed to treat 250 people

answer:

N(t)=2×\(1.7^{t}\)

step by step explain:

before lesson (t=0), she knows 2 words.

after a week (t=1), she knows

2×(1+70%)=3.4 words

after one more week (t=2), she knows

3.4×(1+70%)=5.78 words

one more week later (t=3), she knows

5.78×(1+70%)=9.826 words

and so on ...

from pattern shown above, we know that she knows

2×\(1.7^{t}\) words after t weeks

so N(t)=2×\(1.7^{t}\)

after 4 weeks (t=4), she knows 2×\(1.7^{4}\)=16.7042≈17 words

for learning 5000 words, she need:

2×\(1.7^{t}\)=5000

   \(1.7^{t}\)=2500

t log(1.7)=log(2500)

         t=\(\frac{log(2500)}{log(1.7)}\)

          =14.7448727

          ≈15 (round up)

Answer:

(a) N(t) = 2(1.7)^t

(b) 17

(c) 15

Step-by-step explanation:

(a) N(t) = 2(1.7)^t

There is a 2 because she starts with 2 words. The 1.7 is since her vocabulary grows by 70%. Finally, t represents the weeks. (it is an exponent)

(b) Just plug in the equation

N(4) = 2(1.7)^4

N(4) = 2(8.3521)

N(4) = 16.7042

Round, so it is 17

(c) Once again, plug in the equation

5000 = 2(1.7)^t

2500 = (1.7)^t

use a calculator for the part below

log1.7(2500) = log1.7(1.7)*t

t = log1.7(2500)

t = 14.7448

The estimated monthly average daily radiation on a horizontal surface in June in Amman is approximately 7.35 kWh/m(^2)/day.

To estimate the monthly average daily radiation on a horizontal surface H in June in Amman, we can use the following equation:

\([H = S \times H_s \times \frac{\sin(\phi)\sin(\delta)+\cos(\phi)\cos(\delta)\cos(H_a)}{\pi}]\)

where:

S is the solar constant, which is approximately equal to 1367 W/m(^2);

\(H(_s)\) is the average number of sunshine hours per day in Amman in June, which is given as 10 hours;

(\(\phi\)) is the latitude of the location, which for Amman is approximately 31.9 degrees North;

(\(\delta\)) is the solar declination angle, which is a function of the day of the year and can be calculated using various methods such as the one given in the answer to Q1;

\(H(_a)\) is the hour angle, which is the difference between the local solar time and solar noon, and can also be calculated using various methods such as the one given in the answer to Q1.

Substituting the given values, we get:

\([H = 1367 \times 10 \times \frac{\sin(31.9)\sin(\delta)+\cos(31.9)\cos(\delta)\cos(H_a)}{\pi}]\)

Since we are only interested in the monthly average daily radiation, we can assume an average value for the solar declination angle and the hour angle over the month of June. For simplicity, we can assume that the solar declination angle (\(\delta\)) is constant at the value it has on June 21, which is approximately 23.5 degrees North. We can also assume that the hour angle \(H(_a)\) varies linearly from -15 degrees at sunrise to +15 degrees at sunset, with an average value of 0 degrees over the day.

Substituting these values, we get:

\([H = 1367 \times 10 \times \frac{\sin(31.9)\sin(23.5)+\cos(31.9)\cos(23.5)\cos(0)}{\pi}]\)

Simplifying the equation, we get:

\([H \approx 7.35 \text{ kWh/m}^2\text{/day}]\)

Therefore, the estimated monthly average daily radiation on a horizontal surface in June in Amman is approximately 7.35 kWh/m(^2)/day.

The energy transferred to the water in 5 minutes is 2700 Joules.

To calculate the energy transferred to the water, we can use the formula:

Energy = Power x Time

where Power = Potential Difference x Current

Given potential difference = 12V and current = 750mA, we can calculate the power as:

Power = 12V x 750mA = 9W

Now, the time taken to heat the water is given as 5 minutes. We need to convert this into seconds to use the SI unit of power, which is watts. So,

Time = 5 minutes = 300 seconds

Putting the values in the formula for energy, we get:

Energy = Power x Time
Energy = 9W x 300s
Energy = 2700 Joules

The bookmark has dimensions of 19 cm by 8 cm.

Given, the perimeter of a bookmark = 54 cmThe area of a bookmark = 152 sq cm

Let's assume the length of the bookmark as 'l' and the breadth as 'b'.Since, Perimeter of a rectangle = 2(l + b)Here, Perimeter = 54 cm2(l + b) = 54l + b = 54/2 - Equation 1 (Dividing by 2 into both sides)l + b

= 27 - Equation 2Area of a rectangle

= 152 - Equation 3l × b = 152

From Equation 2, b = 27 - substitute the value of b in Equation 3.l × (27 - l) = 15227l - l² - 152 = 0l² - 27l + 152 = 0Factorizing, we get (l - 8) (l - 19) = 0l = 8 or 19If l = 8 cm, then the breadth of the rectangle will be 19 cm. As the product of length and breadth should be 152 sq cm. But in this case, it's not equal to 152 sq cm.

Answer:

The value of x + y is   -16.

Step-by-step explanation:

If each term is calculated by multiplying the previous one times 5 and then subtracting 20 from that result, then we can use that information to relate the first term (x) and the second one (0).

Following the info above, the following equation applies:

0 = 5 x - 20

then we solve for x:

5x = 20

x = 20/5

x = 4

The height of the building is approximately 125 feet to the nearest foot.

What is angle of incidence?

The angle of incidence is the angle formed by a ray of light or other wave as it approaches a surface, and a line perpendicular to that surface (known as the normal). It is the angle between the incident ray and the normal

We can use trigonometry to solve this problem. Let's assume the height of the building "h".

First, we need to find the distance between the man's eye level and the ground. We can use tangent function:

tan(85°) = h / 20

Solving for h, we get:

h = 20 * tan(85°)

h ≈ 125.36 feet

Therefore, the height of the building is approximately 125 feet to the nearest foot.

Answer:

y = -3x - 1

Step-by-step explanation:

The slope-intercept form is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Point (-1, 2) (1, -4)

m = -6 / 2 = -3

Y-intercept is located at (0, - 1)

So, the equation is y = -3x - 1

You can substitute any vector v to find its image under the transformation t.

By multiplying the transformation by the vector, we can determine the image of a given vector under the linear transformation t. Let's call the given vectors v1, v2, and v3, as well as the images that correspond to them, t(v1), t(v2), and t(v3), respectively.

Given:

t(1, 1, 1) = (2, 0, -1) t(0, -1, 2) = (-2, 5, -1) t(1, 0, 1) = (1, 1, 0) Using the information provided, we can construct a system of equations:

This system of equations can be represented as: x1(1, 1) + x2(0, -1, 2) + x3(1, 0, 1) = (2, 0, -1) y1(1, 1) + y2(0, -1, 2) + y3(1, 0, 1) = (-2, 5, -1) z1(1, 1) + z2(0, -1, 2) + z3(1, 0, 1) = (1, 1, 0)

| 1 0 1 | | x1 0 1 | | 2 0 -1 | | 1 -1 0 | = |-2 5 -1 | | 1 2 1 | | x3 2 1 | | 1 1 0 | We can use matrix inversion to solve this system. The matrix on the left will be referred to as A, and the matrix on the right will be referred to as B. A * X = B In order to determine X, we can multiply both sides of the equation by the inverse of A:

We have: A1 * A = A1 * B because A1 * A is the identity matrix.

Now that we know the inverse of A, we can find X by multiplying it by B: X = A * B.

We can use matrix row operations to reduce A to the identity matrix and keep track of the row operations performed to apply the same operations to the identity matrix. A = | 1 0 1 | | 1 -1 0 | | 1 2 1 |

| 1 0 1 | | 1 0 1 | | 1 -1 0 | | 1 2 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | | 0 0 1 | The matrix A has been reduced to the identity matrix. As a result, A1 is:

A1 = | 1 0 0 | | 0 0 1 | Now, we can find X by multiplying A1 by B:

A * B = | 1 0 0 | | 2 0 -1 | | 0 0 1 | | 1 0 0 | = | 2 0 -1 | | 2 5 -1 | | 1 1 0 | The system of equations' solution reads as follows:

X = | 2 0 - 1 |

\(f(g(x))\\\\f\bigg(\dfrac{1}{3x}\bigg)=\dfrac{1}{3(\frac{1}{3x})}\quad =\dfrac{1}{\frac{1}{x}}\quad =x\\\\\\\\\\g(f(x))\\\\g\bigg(\dfrac{1}{3x}\bigg)=\dfrac{1}{3(\frac{1}{3x})}\quad =\dfrac{1}{\frac{1}{x}}\quad =x\)

We have demonstrated using the Intermediate Value Theorem that the polynomial function has a real zero between 1 and 7.

To apply the Intermediate Value Theorem to the polynomial function f(x) = x^3 - x - 4 and show that it has a real zero between the integers 1 and 7, we need to verify that f(1) and f(7) have opposite signs.

Let's evaluate f(1) and f(7) to determine their signs:

f(1) = (1)^3 - (1) - 4 = 1 - 1 - 4 = -4

f(7) = (7)^3 - (7) - 4 = 343 - 7 - 4 = 332

From the calculations, we can see that f(1) = -4 and f(7) = 332.

Since f(1) is negative (-4) and f(7) is positive (332), they have opposite signs.

According to the Intermediate Value Theorem, if a continuous function changes sign between two points, then it must have at least one real zero between those points.

Since f(1) = -4 (negative) and f(7) = 332 (positive), the polynomial function f(x) = x^3 - x - 4 must have a real zero between the integers 1 and 7.

Therefore, we have demonstrated using the Intermediate Value Theorem that the polynomial function has a real zero between 1 and 7.
