Answer:

basic = 80g

designer = 120g

Explanation:

simultaneous equations:

2B + 2D = 400g
4B + D = 440g -> D = 440 - 4B

to work out B:
2B + 2(440 - 4B) = 440
2B + 880 - 8B = 440  # divide whole thing by 2 to make it simpler
B + 440 - 4B = 220
-3B = -240 # divide both sides by -1
3B = 240
B = 80

to work out D: (substitute B)
4(80) + D = 440g
320 + D = 440g
D = 120

As per the given data, a basic kite weighs 80 g and a designer kite weighs 120 g.

Marketing is the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging value-added offerings for customers, clients, partners, and society as a whole.

Let's denote the weight of a basic kite as w_b and the weight of a designer kite as w_d.

We can set up a system of equations based on the given information:

2w_b + 2w_d = 400 (equation 1)

4w_b + 1w_d = 440 (equation 2)

We can then solve for w_b and w_d using elimination or substitution.

Using elimination:

Therefore, a basic kite weighs 80 g and a designer kite weighs 120 g.

The term that accurate describes Gustav's physiological response is: alarm reaction.

The alarm reaction stage is characterized by what we can call the "fight-or-flight" response. This occurs when the body receives signal of danger or stress, and thereby puts the body on high alert.

When this occurs, the body initiates psychological response such as increased breathing and heart rate, which prepares the body to either protect or flee from the perceived danger.

Placing the structures encountered by light stimuli when entering the eye in correct order is as follows :

Cornea --> Retina ---> Rods and cones ----> Ganglion cells ---> Optic nerve ----> Thalamus ----> Primary visual cortex

When light enters the eye it will have to travel through these structures before the light stimuli will get to the optic nerve which relates the stimuli to the brain for interpretation and relay of message to the eye.

The cornea is part of the outermost part of the human eye that receives the stimuli before relating it to the retina which in turn sends the stimuli to the rods and cones and so on.

Hence we can conclude that the correct order is as follows : Cornea --> Retina ---> Rods and cones ----> Ganglion cells ---> Optic nerve ----> Thalamus ----> Primary visual cortex.

The probability of Type I error is the likelihood of finding a mean outside

the safe zone for the 4 pools.

In hypothesis testing, a Type I error is the error of rejecting a true null

hypothesis.

From a similar question, the possible parameters are;

The safe pH levels for swimming pools is between 7.2 and 7.8

The standard deviation is 0.2

The probability that the pH is within the safe zone is found as follows;

[tex]The \ z-score, \ Z = \mathbf{\dfrac{\overline x - \mu}{\dfrac{\sigma}{n} }}[/tex]

Which gives;

[tex]\mathbf{P \left(\dfrac{7.2 - 7.5}{\dfrac{0.2}{\sqrt{4} } } < \dfrac{\overline x - \mu}{\sigma} < \dfrac{7.8 - 7.5}{\dfrac{0.2}{\sqrt{4} }} \right)} = P(-3 < Z < 3)[/tex]

P(-3 < Z < 3) = P(Z < 3) - P(Z > -3) = P(Z < 3) - (1 - P(Z < 3))

P(Z < 3) - (1 - P(Z < 3) = 2·P(Z < 3) - 1

2·P(Z < 3) - 1 = 2 × 0.9987 - 1 = 0.9974

The probability that the swimming pool is not safe = 1 - (2·P(Z < 3) - 1)

1 - (2·P(Z < 3) - 1) = 1 - 0.9974 = 0.0026

Using the z-distribution, as we are working with a proportions, it is found that the 99% confidence interval for the proportion of people who consider themselves athletic is (0.0911, 0.1239).

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, the parameters are as follows:

[tex]z = 2.575, n = 2373, \pi = \frac{255}{2373} = 0.1075[/tex]

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1075 - 2.575\sqrt{\frac{0.1075(0.8925)}{2373}} = 0.0911[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1075 + 2.575\sqrt{\frac{0.1075(0.8925)}{2373}} = 0.1239[/tex]
