The chances are that the emission from the manufacturing unit is within the permissible level or not within the permissible level is 0.5525.

The term probability describes the chance that an event will occur. In this case, we know that the probability that the company is exceeding the permissible level is 0.35.

We also know that; probability that the carbon emission is within the permissible level is 1 - 0.35 = 0.65.

The chances are that the emission from the manufacturing unit is within the permissible level or not within the permissible level, hence;  0.65 x 0.85 = 0.5525.

Answer:

\(\huge\boxed{\sf Volume \approx 301.4 \ in.^3}\)

Step-by-step explanation:

Diameter = d = 12 in.

Height = h = 8 in.

We know that,

Radius = d/2

So,

Radius = 12/2

Radius = r = 6 in.

\(\displaystyle Volume \ of \ cone = \frac{\pi r^2h}{3}\)

Put the given data in the above formula as well as π = 3.14.

So,

\(\displaystyle Volume = \frac{(3.14)(6)^2(8)}{3} \\\\Volume = \frac{3.14 \times 36 \times 8}{3} \\\\Volume = \frac{904.32}{3} \\\\Volume \approx 301.4 \ in.^3\\\\\rule[225]{225}{2}\)

Answer:

\( {≈301.4 \: in}^{3} \)

Step-by-step explanation:

First, we need to find the radius of the cone's circular base:

Since d = 12, r = 0,5 × d = 0,5 × 12 = 6

Then, we need to find the area of the cone's circular base:

\(s(base) = \pi \times {r}^{2} = 3.14 \times {6}^{2} = 3.14 \times 36 = 113.04\)

Finally, we can find the volume of the cone:

\(v(cone) = \frac{1}{3} \times s(base) \times h = \frac{1}{3} \times 113.04 \times 8 =301.44≈301.4\)

The given statements involve logical conditions and implications, with comparisons between Jordan, LeBron, Steph, and the Pope.

1. The statement "Jordan being the greatest is sufficient for LeBron not being the greatest" implies that if Jordan is considered the greatest, it automatically excludes the possibility of LeBron being the greatest. This statement assumes an either/or scenario between Jordan and LeBron, where the greatness of one negates the greatness of the other.

2. The statement "Either Steph had the greatest season ever or the Pope is not Catholic" presents a logical disjunction, asserting that one of two options must be true. It suggests that either Steph had an exceptional season or the widely accepted belief that the Pope is Catholic is false. The statement is presented in a form of contrast to emphasize the uniqueness or extremity of one of the options.

3. The statement "LeBron will be MVP if and only if neither Steph nor Jordan wins" establishes a conditional relationship between LeBron being the MVP and the conditions of Steph or Jordan not winning. It implies that for LeBron to become the MVP, it is necessary for both Steph and Jordan to not win. This statement sets up a specific criterion for LeBron's MVP status.

Answer:

i think the answer is (-4,2)

Step-by-step explanation:

The expression 50 * 25 * 2, rewritten correctly using the commutative property and then simplified, is equal to 1250.

The commutative property allows us to change the order of the factors without affecting the product. Starting with the expression 50 * 25 * 2, we can rewrite it using the commutative property as follows:

50 * 25 * 2 = 25 * 50 * 2

Now, to simplify the expression, we can perform the multiplication:

25 * 50 = 1250

Thus, the expression 50 * 25 * 2, rewritten correctly using the commutative property and then simplified, is equal to 1250. By rearranging the order of the factors using the commutative property, we are able to simplify the calculation and obtain the same result.

{the following is if you do not understand my drawing}

There are 4 segments that we can imagine - north, south, east, and west

We can imagine that these lines all meet a circle

There are 360 degrees to a circle. So, if we divide that by 4, we know that each segment is 90 degrees.

(Also, you can probably see that the angles are right angles, or you know that straight lines are 180 degrees, you probably know this information intuitively)

This means that each smaller segment, two in both of our four segments, is 45 degrees.

These 8 sections are each 1/8 of the total circle.

Using the exponential distribution, it is found that the proportion of the population that will visit an emergency room in the next six months is of 0.1813 = 18.13%.

The exponential probability distribution, with mean m, is described by the following mass function:

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

In this function, \(\mu = \frac{1}{m}\) represents the decay parameter.

The probability that x is lower or equal to a is given by:

\(P(X \leq x) = \int\limits^a_0 {f(x)} \, dx\)

The solution of the definite integral gives the cumulative mass function as follows:

\(P(X \leq x) = 1 - e^{-\mu x}\)

In this problem, the mean is of 2.5 years, hence the decay parameter is calculated as follows:

\(\mu = \frac{1}{2.5} = 0.4\)

The proportion of the population that will visit the emergency room in the next six months is P(X < 0.5), as 6 months = 0.5 years, hence:

\(P(X \leq 0.5) = 1 - e^{-0.4 \times 0.5} = 0.1813.\)

The problem asks for the proportion of the population that will visit an emergency room in the next six months.

Step-by-step explanation:

Using ' t ' for the number of minutes.

" 59 > 19 + 5t "

→ Solve for t...

= 59 > 19 + 5t

= 59 - 19 > 5x

= 40 > 5t

= 40/5 > t

= 8 > t

Thus, It will take 8 minutes to add 59 litres of water.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tickets to a family concert cost $10 for adults and $3 for children. The concert organizer collected a total of $900 from ticket sales if 42 adults were at the concert.

The expression can be written as;-

10a + 3c = 900

a = 42

10 x 42 + 3c = 900

420 + 3c = 900

3c = 900 - 420

3c = 180

c = 480 / 3 = 160

Hence, there were 160 kids present at the concert.

The solution of the given system of equations include the following:

C. a = -3 and b = 6.

In order to solve the given system of equations, we would apply the substitution method. For instance, we have the following system of equations:

2a + 3b = 12      .......equation 1.

a = 1/2(b) - 6          .......equation 2.

By using the substitution method to substitute equation 2 into equation 1, we have the following:

2(b/2 - 6) + 3b = 12

b - 12 + 3b = 12

4b = 12 + 12

4b = 24

b = 24/4 = 6.

For the value of a, we have:

a = 1/2(b) - 6

a = 1/2(6) - 6

a = 3 - 6

a = -3.

The group of volunteers can make a total of 200 masks out of 25 yards of fabric.

To calculate the number of masks that can be made, we divide the total amount of fabric (25 yards) by the amount of fabric required per mask (1/8 yard). To do this, we first convert the fraction 1/8 to decimal form, which is 0.125. Then, we divide the total fabric (25 yards) by the fabric required per mask (0.125 yards). This can be done by dividing 25 by 0.125, which equals 200. Therefore, the group of volunteers can make a total of 200 masks out of 25 yards of fabric. Each mask requires 1/8 yard of fabric, so dividing the total fabric by the fabric required per mask gives us the total number of masks that can be made.

Calculation steps:
1. Convert the fraction 1/8 to decimal form: 1/8 = 0.125.
2. Divide the total fabric (25 yards) by the fabric required per mask (0.125 yards):
  25 / 0.125 = 200.
