Answer 1

mean: 25 minutes

standard deviation: 6.1 minutes

A 11 minutes commute time is 2.30 standard deviations away from the mean. In this case, we have, for a normal distribution:

Step-by-step explanation:

Harry’s company can store 50,000 units of their new product in the warehouse, the maximum capacity for the warehouse. They sold 20,000 in pre-orders that will need to be shipped immediately. They can produce 3000 units per week, and they are receiving 1500 orders per week. How long will it take to fill the warehouse to maximum capacity based on the current production rate?

Answers

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Maximum capacity for the warehouse = 50,000 units

Pre-orders = 20,000 units

Number of units produced per week = 3000 units

Number of orders per week = 1500 units

The number of weeks to fill the warehouse to its maximum capacity:

We can make an equation as:

3000M - 1500M - 20,000 = 50,000 ____(1)

M = number of weeks

From (1) we get,

M ( 3000 - 1500 ) - 20,000 = 50,000 ____(2)

1500M - 20,000 = 50,000

1500M = 50,000 + 20,000

1500M = 70,000

M = 46.66 weeks

M = 47 weeks

We can also see that,

From (2),

M ( 3000 - 1500 ) - 20,000

47 x 1500 - 20,000

70,500 - 20,000

50,500

Thus,

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

find the estimated quotient.

1. 4234 devide 51

Answers

The estimated quotient of the division is 83.

In mathematics, a quotient is a quantity created by the division of two integers (from the Latin quotients, meaning "how many times").

The term "quotient" is used frequently in mathematics, and it can also refer to a fraction or a ratio as well as the integer portion of a division (in the case of Euclidean division)(in the case of proper division). For instance, the quotient in the sense of Euclidean division is "6 with a remainder of 2" when 20 (the dividend) is divided by 3 (the divisor).The most common way to represent the quotient is as two integers or two variables split by a horizontal line. The terms "dividend" and "divisor" relate to each component separately, whereas "quotient" describes the entire thing.

Now let us divide 4234 by 51.

4234 ÷ 51 = 83.019...

Therefore the quotient is 83

4234 divided by 51 gives quotient 83 and remainder 1 .

Answers

The true statement is g(-13)= 20.

What is domain and range?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. Mapping or transformation is used to denote a function in math. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

domain = -20 ≤ x ≤ 5

and a range = -5 ≤ g(x) ≤ 45

and g(0) = -2 and g(-9) = 6

First, g(-13)= 20

x=-13 is in our domain  and 20 is also in our range .

So this is true for g(-13)= 20.

Now, g(-4) = -11

-11 does not comes under the range.

So this statement is not true.

Again,  g(0) = 2 is false because  g(0) = - 2.

and,  g(7) = -1 D

12 cos^2 ( x ) − sin ( x ) − 6 = 0

Answers

The solutions to the trigonometric equation 12cos²(x) - sin(x) - 6 = 0 are given as follows:

x = 42º and x = 228º.

What is the solution to the trigonometric equation?

The equation is given as follows:

12cos²(x) - sin(x) - 6 = 0

The following identity is applied:

sin²(x) + cos²(x) = 1.

Hence:

cos²(x) = 1 - sin²(x).

Replacing this identity into the equation, we have that:

12(1 - sin²(x)) - sin(x) - 6 = 0

12 - 12sin²(x) - sin(x) - 6 = 0

12sin²(x) + sin(x) - 6 = 0.

The following transformation is applied:

y = sin(x).

Hence the equation is:

12y² + y - 6 = 0.

Which, using a calculator, has the solutions given by:

y = -3/4, y = 2/3.

Then the solutions for the variable x are given as follows:

sin(x) = -3/4 -> x = arcsin(-3/4) = 228º.sin(x) = 2/3 -> x = arcsin(2/3) = 42º.

The front of a big wave is approaching a beach at a constant speed of 11.6ms-! When it is 30 m away from a boy on the beach, the wave starts decelerating at a constant rate of 1.6 ms-2 and the boy walks away from the sea at a constant speed of 2 ms-! Show that the wave will not reach the boy and find the minimum distance between the boy and the wave.

Answers

Answer:

minimum distance between the boy and the wave is 1.2 m

Step-by-step explanation:

Use v = u + at, with v as 0, to find how long it takes for the wave to decelerate to 0 m/s.

0 = 11.6 - 1.6t

t = 7.25s

Then find how far the wave has traveled by substituting in s = ut + 1/2 at²

s = 11.6 * 7.25 + 1/2(-1.6)(7.25²)

s = 42.05m

Find out how far the he has traveled in the same time

s = vt + 30 (since he was 30m ahead)

s = 2*7.25 + 30

s = 44.5m

The boy has traveled a greater distance so the wave does not reach by the time it decelerates to 0m/s

Find the time at which the wave reaches a speed of 2m/s.

v = u + at

2 = 11.6 - 1.6t

t = 6s

Now find the distance traveled by the wave in that time

s = ut + 1/2 at²

s = (11.6*6) + 1/2(-1.6)(6²)

s = 40.8m

Now find the distance traveled by the boy in that same time

s = vt + 30

s = 2*6 + 30

s = 42m

Find the difference, which is the minimum separation

42 - 40.8 = 1.2m

We need to select all the functions from the options that have a period of 2π.

If a function has period P, the function f(x) repeats its values every time x is a multiple of P.

Thus, by analyzing the graph of periodic functions, we can determine their period.

And the functions y = csc x and y = sec x have period 2π.

Therefore, the functions that have period 2π are:
