The probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice is approximately 0.5949 (rounded off to third decimal place).

To find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice, we need to find the cumulative distribution function (CDF) of a normal distribution with a mean of 500 and standard deviation 4.

Using the Z-score formula, we can calculate the Z-score for 499 ml of juice: (499-500)/4 = -0.25

Next, we use a standard normal table to find the probability of a Z-score less than -0.25, which is 0.4051.

Finally, we use the CDF formula for a normal distribution to find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice:

P(X < 499) = 1 - P(X >= 499) = 1 - 0.4051 = 0.5949

Therefore, the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice is approximately 0.5949 (rounded off to the third decimal place).

Answer:

x = 4cm

Step-by-step explanation:

If the triangle is equilateral, then we already know one of the sides has a length of 3+5 (8).

This, therefore, means the 2 other sides' lengths are also equal to eight, which means all we need to do to find x is subtract 4 from 8, which gives us 4.

Hope this helps

Answer:

[tex]x=\dfrac{20}{3}\; \sf cm[/tex]

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other two sides, then this line divides those two sides proportionally.

Applying the side-splitter theorem:

[tex]\implies \dfrac{3}{5}=\dfrac{4}{x}[/tex]

Cross multiply:

[tex]\implies 3 \cdot x=4 \cdot 5[/tex]

[tex]\implies 3x=20[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3x}{3}=\dfrac{20}{3}[/tex]

Mr. Saver's nominal interest rate is 8%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that the interest he earns during t = 0.5 to t = 1.5 is 1.0816 times the interest he earns during t = 0 to t = 1. We can use this information to set up an equation as follows:

P(1+R/4)²=1.0816×P(1+R/4)

We can simplify this equation by canceling out the P and the (1+R/4) on the right side:

(1+R/4)=1.0816

We can then solve for R:

R/4=√1.0816-1

R=0.08 is the exact value of R.

Now multiply with 100

0.08×100=8%

Hence, Mr. Saver's nominal interest rate is 8%.

The object will reach a maximum height of approximately -89,898.36 meters, or 89.9 kilometers, above the Moon's surface before it falls back down.

Escape velocity is the minimum speed an object must have in order to escape the gravitational pull of a celestial body, such as a planet or moon, and travel into space. It is calculated based on the mass and radius of the celestial body and the distance of the object from its surface. The greater the mass and radius of the celestial body, the greater the escape velocity.

The formula for escape velocity is given by v_escape = √(2GM/R), where G is the gravitational constant, M is the mass of the object, and R is the radius of the object.

In this case, v_escape = 2.4 × 10³ m/s and v_projected = 2.0 × 10³ m/s.

The maximum height can be calculated using the following formula:

h = (v_projected^2 - v_escape^2) / (2g), where g is the acceleration due to gravity.

Since the escape velocity is greater than the projected velocity, the object will not escape the Moon's surface and will eventually fall back down. The maximum height it reaches is given by:

h = (2.0 × 10³ m/s)^2 - (2.4 × 10³ m/s)^2 / (2 * 9.8 m/s^2) = (4.0 × 10^6 - 5.76 × 10^6) m / 19.6 = -1.76 × 10^6 m / 19.6 = -89,898.36 m.

The object will reach a maximum height of approximately -89,898.36 meters, or 89.9 kilometers, above the Moon's surface before it falls back down.

The random variable's pdf is f(x) = (3/8) x^2 , x ∈ [0, 2].

Finding the normalizing constant that equals the integral of the pdf over the support of the random variable yields the constant in the pdf (probability density function).

The random variable's support is the interval [0, 2]. The normalizing constant can be calculated as follows:

∫_0^2 x^2 dx = [x^3/3]

_0^2 = (8/3) - (0) = 8/3

So, in the pdf, the constant is 1/(8/3) = 3/8, rounded to the second decimal place.

As a result, the random variable's pdf is:

The volume of the solid is -30π cubic units

The volume of the solid obtained by rotating the region about the x-axis is given by the formula:

V = π * ∫[a,b] (R^2 - (x-c)^2) dx

Where:

a = lower limit of x-coordinate of the region

b = upper limit of x-coordinate of the region

c = axis of rotation

R = distance from the x-axis to the boundary of the region

For the given region, a = 0, b = 10, c = 10, and R = 2.

So the volume of the solid is:

V = π * ∫[0,10] (2^2 - (x-10)^2) dx

= π * ∫[0,10] (4 - (x-10)^2) dx

= π * [2x - (x-10)^2/2 + C] evaluated at x=10 and x=0

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

Step-by-step explanation:

The equation of the ellipse is (x^2)/4 + y^2 = 2. To find the equation of the normal line at the point (2, 1), we first need to find the slope of the tangent line at that point. To do this, we can use the formula for the slope of a tangent line:

slope = -(d/dx)(f(x)) / (d/dy)(f(y))

Where f(x) and f(y) are the equations of the ellipse.

So,

slope = -(x/2)/y = -x/2y

Now we can substitute the point (2, 1) into the equation for the slope:

slope = -(2/2)/1 = -1

We know that the slope of the normal line is the negative reciprocal of the slope of the tangent line, so the slope of the normal line is 1.

To find the equation of the normal line, we can use the point-slope form of a line:

y - y1 = m(x - x1)

Where (x1, y1) is the point on the line and m is the slope.

So,

y - 1 = 1(x - 2)

Simplifying, we get:

y = x - 1

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

The limit of a constant function is equal to the constant. The limit of a linear function is equal to the number x is approaching.

A limit is defined as a value that a function approaches the output for the given input values.

Limit of a constant :-

We know that the limit of a function exists, only and only if the left-hand limit (LHL) and the right-hand limit (RHL) exists and are equal to one another. And, the value of the limit of that function is equal to the common value, LHL = RHL = f(x).

We need to find the limit of a constant. So, let us assume a function, f(x) = c, where c is a constant. We are assuming that we need to find the limit of this constant function at x = a, i.e. we need to find the value of

[tex]\lim_{x \to \ a} f(x)[/tex]

Plot the graph, y = c, (attached)

Let us calculate the left hand limit first.

LHL = [tex]\lim_{x \to \ -a} f(x)[/tex]

We can see that at x = -a, the value of f(x) is c.

LHL = c.....(i)

Similarly,

For right-hand limit,

We have at x = +a, the value of f(x) is c.

RHL = c....(ii)

Also, Also, the value of our function at a, i.e., f(a) = c

Thus, by equation (i), (ii) and (iii), we can say that

[tex]\lim_{x \to \ a} f(x) = c[/tex]

Q1=0.037037

Med = 0.037037

Q3 = 0.346790

Max = 346

Step-by-step explanation:

To convert the numbers to decimal, we can divide the number before the slash by the number after the slash. So for example, 1/27 becomes 0.037037.

After converting the numbers to decimal and arranging them in ascending order, we get:

0.02, 0.037037, 0.03448, 0.040816, 0.346790, 346

To find the Q1, median (Med), Q3, and other measures of central tendency and spread for this list of numbers, we first need to order the numbers in ascending order:

0.02, 0.03448, 0.037037, 0.040816, 0.346790, 346

Q1 is the value that separates the lowest 25% of the data from the rest of the data. To find Q1, we need to find the median of the lower half of the data set. Since there are 6 numbers in the set and Q1 is the middle value of the lower half, Q1 would be the 3rd number in the ordered set, which is 0.03448.

Med is the middle value of the data set. Since there are 6 numbers in the set, the median would be the 3rd and 4th numbers, which are 0.03448 and 0.037037.

Q3 is the value that separates the highest 25% of the data from the rest of the data. To find Q3, we need to find the median of the upper half of the data set. Since there are 6 numbers in the set and Q3 is the middle value of the upper half, Q3 would be the 5th number in the ordered set, which is 0.346790.

Min is the smallest value of the dataset, which is 0.02

Max is the largest value of the dataset, which is 346
