A company sells kites. It sells basic kites and designer kite's. 2 basic kites and 2 designer kites have a total weight of 400 g. 4 basic kites and 1 designer kite have a total weight of 440 g. Work out the weight of a basic kite and the weight of a designer kite.
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.
What is marketing?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:
Multiply equation 1 by 2: 4w_b + 4w_d = 800Subtract equation 2 from the above: (4w_b + 4w_d) - (4w_b + 1w_d) = 800 - 440Simplify: 3w_d = 360Solve for w_d: w_d = 120Substitute w_d into equation 1 and solve for w_b: w_b = 80Therefore, a basic kite weighs 80 g and a designer kite weighs 120 g.

Gustav was out for his daily walk when he was approached by a thief who demanded his wallet. He immediately felt an increase in his breathing and heart rate. Which of the following accurately describes gustav’s physiological response?.
The term that accurate describes Gustav's physiological response is: alarm reaction.
What is the Alarm Reaction Stage?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.
Therefore, the term that accurate describes Gustav's physiological response is: alarm reaction.

Light stimuli entering the eye encounter a series of structures while traveling to the brain. Place the structures in the correct order.
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
Steps followed by the light stimuli
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.

Answer:
A, B, and E are the correct options.
Explanation:
Two disjoint pairs of consecutive sides are congruent by definition - QP≅QR and QR is not congruent to RS (one side can’t be used in both pairs);
One diagonal (segment QS, the main diagonal) is the perpendicular bisector of the other diagonal (segment PR, the cross diagonal), so PM≅MR;
The opposite angles at the endpoints of the cross diagonal are congruent, thus ∠QPS≅∠QRS.
∠PQR is not congruent to ∠PSR, because they are not angles at the endpoints of the cross diagonal.
Therefore, A, B, and E are the correct options.

How to get the return on investment?
The return on investment is given by the formula:
ROI = 100%*(selling price - cost)/(cost).
Here we have:
Selling price = $85Cost = $65.Replacing that on the above formula, we get:
ROI = 100%*($85 - $65)/$65= 30.77%

There are 1,000 golden delicious and 1,000 red delicious apples in a cooler. In a random sample of 75 of the golden delicious apples, 48 had blemishes. In a random sample of 75 of the red delicious apples, 42 had blemishes. Assume all conditions for inference have been met. Which of the following is closest to the interval estimate of the difference in the numbers of apples with blemishes (golden delicious minus red delicious) at a 98 percent level of confidence?.
Using the z-distribution, it is found that the 98% confidence interval for the difference in the proportion of apples with blemishes is of (-0.1055, 0.2655).
Sample proportions and standard errorsThe sample proportions, and standard error for each sample, are given as follows:
[tex]p_G = \frac{48}{75} = 0.64[/tex]
[tex]s_G = \sqrt{\frac{0.64(0.36)}{75}} = 0.0554[/tex]
[tex]p_R = \frac{42}{75} = 0.56[/tex]
[tex]s_R = \sqrt{\frac{0.56(0.44)}{75}} = 0.0573[/tex]
Distribution of differencesThe distribution of differences has mean and standard error given by:
[tex]p = p_G - p_R = 0.64 - 0.56 = 0.08[/tex]
[tex]s = \sqrt{s_G^2 + s_R^2} = \sqrt{0.0554^2 + 0.0573^2} = 0.0797[/tex]
What is the confidence interval?The confidence interval is given by:
[tex]p \pm zs[/tex]
z is the critical value. We have a 98% confidence level, hence, using a z-distribution calculator, it is of z = 2.327.
The lower limit of this interval is:
[tex]\pi - zs = 0.08 - 2.327(0.0797) = -0.1055[/tex]
The upper limit of this interval is:

Consider the situation in which the health inspector finds the sample mean of the 4 pools to be outside the safe ph levels. As a result, the inspector declares that the population mean is not 7. 5. However, if the population mean really is 7. 5, the inspector will have made an error. Such an error is called a type i error. Find the probability that the inspector will make a type i error with the sample of 4 pools. Show your work.
The probability of Type I error is the likelihood of finding a mean outside
the safe zone for the 4 pools.
The probability that the inspector will make a Type I error is 0.0026What is a Type I error and what is the probability that it will occur?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
Which gives;
The probability that the mean will be seen as not in the safe zone and therefore not 7.5 is 0.0026 and the probability that the inspector will make a Type I error is 0.0026Learn more about hypothesis testing here:
