The point estimate for the lifetime of a certain type of battery is 120.1 hours.

Let X represent the battery's lifetime. X has a normal distribution with a standard deviation of 20 hours. The sample size is 50, and the average lifetime is 120.1 hours.

Calculating the mean of a sample drawn from the population yields a point estimate of the population's mean. The mean is calculated as the sum of all sample values divided by the number of values.

A single value estimate of a parameter is referred to as a point estimate. A sample mean, for example, is a point estimate of the population mean. An interval estimate provides a range of values within which the parameter is expected to fall. The population mean point estimate is sample mean and this is 120.1 hours.

The composite functions and their domains are listed as follows:

a) (f ∘ g)(x) = sin(2x/(x + 5)), domain is all real values except x = -5.

b) (g ∘ f)(x) = sin(2x)/(sin(2x) + 5), domain is all real values except x = -5 and the values of x for which sin(2x) + 5 = 0.

c) (f ∘ f)(x) = sin(sin(2x)), domain is all real values.

d) (g ∘ g)(x) = x/(6x + 5), domain is all real values except x = -5 and x = -5/6.

The composite functions are found applying the inner function as the input to the outer function, according to the rule presented as follows:

(f ∘ g)(x) = f(g(x)).

The domain is the set of values that respect all the input constraints of the inner function, of the outer function, and of the composite function.

For this problem, the functions are given as follows:

For item a, the inner function g is applied as the input to the outer function f, hence:

f(g(x)) = sin(2x/(x + 5))

The sine has no constrains, the fraction cannot have a denominator zero, hence the domain is composed by all real values except x = -5.

The length of i will be 531.3 inch when h is 300 inch and ∠G is 30° and ∠H is 29°.

When two straight lines or rays intersect at a shared terminal, an angle is generated. An angle's vertex is the common point of contact. The difference in direction between two lines or surfaces is defined as an angle. Angles are expressed in degrees. From a same point, the two hands draw separate sets of lines. Angle refers to these groups of lines that originate from a common point. Every minute, the two hands create various angles. In real life, one example of an angle is a clock.

Here,

∠I=180-(30+29)

=180-59

∠I=121°

h/sin H=i/sin I

300/sin 29=i/sin 121

i=300*sin 121/sin 29

i=531.3 inch

As per the concept of system of linear equations, the maximum revenue of this basket ball match is $3.4

Linear equation:

Linear equation refers the one variable is an equation in which there is only one variable present. And it is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.

Given,

A baseball team plays in a stadium that holds 66000 spectators. With the ticket price at $10 the average attendance has been 28000. When the price dropped to $7, the average attendance rose to 33000. Assume that attendance is linearly related to ticket price.

Here we need to find the ticket price would maximize revenue.

In order to find the ticket price for the maximum revenue,

We have to identify the details from the given question,

Total seating capacity = 66,000

When ticket price $10 then the attendance 28,000

When ticket price $7 then the attendance 33,000

Let us consider the x be the maximum revenue ticket price.

Now, to solve this we have to find the slope for the equation,

That is,

=> m = (33000 - 28000)/(7 - 10)

=> m = 5000/-3

=>  m = -5000/3

=> m = 1666.6

Then the revenue equation is written as,

=> y = (10 - x) * (28,000 + 1666.6x)

=> y = 280000-11334x-1666.6x²

If we plot the this function into the graph, then we get the graph like the following.

Therefore, the solution of the graph is 3.4.

to find the exterior angle, find the interior angle first and then use the straight line.

interior angle = 180° therefore,

75° + 64° + X = 180

139° + X = 180°

X = 180° - 139°

X = 41° (not the answer)

a straight line = 180°

X = 41°

Y - the exterior angle

41° + Y = 180°

Step-by-step explanation:

Simple interest of $325 was accrued on a principal of $26,000.00 for a period of 0.25 years (13 weeks) at a rate of 5% per year, bringing the total amount due to $26,325.00 (principal plus interest).

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a creditor will only charge interest on the principal sum, and a borrower will never be required to pay additional interest on the interest that has already accrued.

Here,

A = $26,325.00

I = A - P = $325.00

A is equal to P(1 + rt).

The first step is to convert R percent to r a decimal, which is equal to R/100 = 5%/100 = 0.05 per year.

For ease, let's convert time to years: 13 weeks / 52 weeks / year = 0.25 years.

How to resolve our equation

A = 26000(1 + (0.05 × 0.25))  = $26,325.00

Simple interest accrued on a principal of $26,000.00 at a rate of 5% per year for 0.25 years (13 weeks) totaling $26,325.00 (principal plus interest).

When we see that we can rewrite it as (2,0) and (5,0). This is because when it is telling us just “x” we know “y” (the second number in the parentheses) is 0.

The dimensions of the rectangular paint of perimeter 104.09 inches are given as follows:

The perimeter of any polygon, including a rectangle, is given by the sum of all the lengths of the outer edges of the figure.

Hence, for a rectangle of height h and width w, the perimeter is given by twice the sum of these dimensions, hence it is given as follows:

P = 2(h + w).

In this problem, the perimeter has the value given as follows:

P = 104.09 inches.

Hence:

2(h + w) = 104.09

h + w = 104.09/2

h + w = 52.045 inches.

The painting is 5.72 inches taller than it is​ wide, hence:

h = 5.72 + w.

Then the height is obtained as follows:

5.72 + w + w = 52.045

2w = (52.045 - 5.72)

w = (52.045 - 5.72)/2

w = 23.16 inches.

Then the height of the rectangular painting is given as follows:
