Meteorologists in Texas want to increase the amount of rain delivered by thunderheads by seeding the clouds. Without seeding, thunderheads produce, on average, 300 acrefeet. The meteorologists randomly selected 29 clouds which they seeded with silver iodide to test their theory that average acrefeet is more.
What conclusion can they reach based on the above output when they set the significance level to be 0.10?
a.The data does not provided statistical evidence that the average acrefeet from seeded clouds is more than 300.
b.The data does provide statistical evidence that the average acrefeet from seeded clouds is more than 300.
c.The data does not provided statistical evidence that the sample average acrefeet from seeded clouds is more than 300.
d.Two of the above are correct.
e.We can not draw conclusions based on the above statistical output because the conditions are not met due to the extreme out
Answers
There is no statistical support in the data for the claim that seeded clouds typically cover more than 300 acres per foot by average acrefeet.
Since the significance level is set at 0.10, the meteorologists can conclude that the data does not provide statistical evidence that the average acrefeet from seeded clouds is more than 300.
This is because the calculated p-value is greater than the significance level. This means that there is not sufficient evidence to reject the null hypothesis, which states that the average acrefeet from seeded clouds is no greater than 300.

How to find the missing part of a triangle?
From the given triangle, we are told that;
LN = 5x - 8
NM = 12
∠KNL = (13x - 14)°
Now, since KN is an altitude in ΔKLM, it means that KN is perpendicular to LM and as such ∠KNL is a right angle which is 90 degrees. Thus;
(13x - 14)° = 90

Angle ABC is a straight angle.
Angles ABD and DBC are right angles.
Angles CBE and DBE are acute angles.
Angle ABE is an obtuse angle.
Angles
The sum of the three angles in any triangle is always 180°.
a + b + c = 180°
Knowing that the sum of the angles of triangle is 180° can help you to solve problems about triangles.
Angles
In this triangle, angle b is a right angle and angle c = 40°. What is the measure of angle a?
a + b + c = 180°
Since b is a right angle, b = 90°.
The problem states that c = 40°.
Therefore, a + 90° + 40° = 180°
a + 130° = 180°
a + 130° − 130° = 180° − 130°
a = 50°

Answer:
Step-by-step explanation:
The graph of the parent function f(x) = |x|
transformed function g(x) = |x – h|
To Find : How does changing the value of h affect the vertex?
Positive values of h shift the graph
Negative values of h shift the graph
Solution:
f(x) = |x|
is f(x) = x for x ≥ 0
f(x) = -x for x < 0
g(x) = |x – h|
Positive values of h shift the graph to the right
f(x) = x - h for x ≥ 0
f(x) = h - x for x < h
As values of h increase graph keep shifting to right
Vertex is ( h , 0) Vertex keep shifting to right with increases value of h

Answers
Juan's Net Cash Flow at the end of the month is -$230 and his Ending Cash is $270.
To calculate Juan's Net Cash Flow and Ending Cash, you need to subtract his expenses from his income.
Juan's income is $4750 per month. His essential expenses, including rent, medical costs, insurance, and tax, total $2800 per month. He also spends $750 on food, $400 on clothes, and $530 on video games and movies, for a total of $2680 in non-essential expenses.
Therefore, his total expenses are $2800 + $2680 = $5480.
His Net Cash Flow is his income minus his expenses, which is $4750 - $5480 = -$730.
His Ending Cash is his Net Cash Flow plus his starting balance of $500, which is -$730 + $500 = $270.
Therefore, the correct answer is option C: Net Cash Flow: -$230, Ending Cash: $270.
suppose that a box contains 6 cameras and that 5 of them are defective. a sample of 2 cameras is selected at random ( without replacement). define the random variable x as the number of defective cameras in the sample. write the probability distribution for x .write your answer in fraction form or round to 3 decimal places.
Answers
If x is the number of defective cameras in the 2-size sample, that means that:
P(x = 0) = 0 (since there are no 2 cameras that can be selected without replacement that are not defective)
P(x = 1) = 5/15 = 1/3 (since there are 15 total ways to select a distinct sample and only 5 of these would have the non-defective one in them)
P(x = 2) = 10/15 = 2/3 (since there are 15 total ways to select a distinct sample and 10 of these would NOT have the non-defective one in them)

Answers
To prove that AC = BD, we can use the symmetric property. The symmetric property states that if two quantities are equal, then their opposites are also equal.
In this case, we are given that AB = CD. Since AB and CD are opposite quantities (they are the lengths of the diagonals of a rectangle), we can use the symmetric property to conclude that AC = BD.
Therefore, the reason that can be used to justify statement 4 in the proof is the symmetric property.

How to obtain the intervals in which the function is increasing?The function in this problem is defined as follows:
h(x) = 5x³ - 3x^5.
To obtain the intervals for increase of decrease, the critical points of the function need to be obtained, which are the values of x for which the derivative is of zero.
The derivative of the function in this problem is given as follows:
h'(x) = 15x² - 15x^4.
Hence the critical points of the function are given as follows:

two planes flying at the same altitude are heading toward jwd airport. the paths of these planes form a right triangle. the jet is flying due east toward jwd at 450 mph. the turboprop is approaching jwd from the south at 275 mph. when each is 100 miles from the airport how fast is the distance between the planes changing?
Answers
The speed of the distance between the two planes is increasing at 325 mph as they approach JWD Airport.
The two planes form a right triangle, with the jet flying due east at 450 mph and the turboprop approaching from the south at 275 mph. The hypotenuse of the triangle is the distance between the planes, and the length of the hypotenuse is changing as the planes approach the airport. The rate of change of the length of the hypotenuse is equal to the sum of the rates of change of the two sides of the triangle, which are the speeds of the jet and the turboprop. As they are both 100 miles from the airport, the speed of the distance between the two planes is equal to the sum of the two speeds, or 450 mph + 275 mph = 325 mph. Therefore, the distance between the two planes is changing at a rate of 325 mph.
Rate of change of distance between the planes = Rate of change of jet + Rate of change of turboprop
= 450 mph + 275 mph

ABDC is a quadrilateral with two non-parallel sides. It has two pairs of opposite sides which are parallel. It is also known as a trapezoid.
ABDC is a four-sided figure with two pairs of opposite sides that are parallel. This type of quadrilateral is also known as a trapezoid. A trapezoid has two non-parallel sides, while the other two sides are parallel to each other. In this case, the two parallel lines are L1 and L4, while L2 and L3 are the two non-parallel sides. We can see that the point C on L2 is a distance of 4cm from L1, and L4 is a line that is parallel to L1 and passes through C. Finally, L4 intersects L3 at the point D, which completes the trapezoid ABDC.
The length of AB can be determined by using the Pythagorean Theorem. We know that the length of L1 is 8 cm, so the length of AB is 3 cm.
example
AB = √(8^2 - 4^2) = √64 - 16 = √48 = 6 cm

i.e. 13 = 3/5 x (total money received by madison)
or we can say that total money received by madison = (5/3) x 13
= 65/3
= 21.6
Hence, the total money received by madison was $ 21.6

Answers
The value x is 28. By using Pythagorean theorem on the given triangle.
What is the meaning of the nearest tenth?
To write a decimal number up to one decimal place, round it to the nearest tenth. This is done in a way that leaves one digit after the decimal point after rounding.
Given that,
DC = 28
BC = 32
Assume that, AB = a and AD = b
Applying Pythagorean theorem on △BCD:
BC² = DC² + DB²
Putting BC = 32 and DC = 28 in the above equation:
32² = 28² + DB²
DB² = 32² - 28²
DB² = 32² - 28²
DB² = 240
The length of AC is CD + DA = 28 + b.
Now applying Pythagorean theorem on △ABC:
BC² = AB² + AC²
32² = a² + (28 + b)²
a² = 32² - (28 + b)² .....(i)
Now applying Pythagorean theorem on △ABD:
AB² = AD² + BD²
a² = b² + 240 ....(ii)
Now comparing equation (i) and equation (ii)
32² - (28 + b)² = b² + 240
1024 - (28² + 56b + b²) = b² + 240
1024 - 784 - 56b - b² = b² + 240
b² + 240 - 1024 + 784 + 56b + b² = 0
2b² + 56b = 0
2b(b + 28) = 0
Either,
2b = 0, b + 28 =0
b = 0, b = -28
Since the value of b can't be negative. Thus b = 0.
The length of AC is CD + DA = 28 + b = 28.
