Use the given information to find the p-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject
the null hypothesis or fail to reject the null hypothesis).
The test statistic in a right-tailed test is z=0.52.
A. 0.3015; fail to reject the null hypothesis
B. 0.0195; reject the null hypothesis
C. 0.3015; reject the null hypothesis
D. 0.6030; fail to reject the null hypothesis
A. 0.3015; fail to reject the null hypothesis
The test statistic is z = 0.52 and p-value (0.3015) is greater than the significance level (0.05)
Given data ,
Under the premise that the null hypothesis is true, the p-value is the likelihood of witnessing a test statistic that is as severe as the one computed or even more extreme. The p-value of a right-tailed test is the likelihood of seeing a test statistic that is higher than or equal to the computed test statistic.
We can compare the test statistic to the critical value or use a conventional normal distribution table to calculate the p-value given that the test statistic is z = 0.52 and the significance threshold is 0.05
Looking up the p-value corresponding to z = 0.52 in a standard normal distribution table or using a calculator, we find that the p-value is approximately 0.3015.
Since the p-value (0.3015) is greater than the significance level (0.05), we fail to reject the null hypothesis.
Hence , 0.3015; fail to reject the null hypothesis

The height of a triangle is 3
feet less than the base. The area of the triangle is 90
square feet. Find the length of the base and the height of the triangle.
The length of the base is 15 feet and the height is 12 feet.
What is a triangle?The three line fragments are known as the sides of the triangle, while the three places where they converge are known as the vertices of the triangle.
Let suppose, base of the triangle = x
Then, according to the problem, the height of the triangle is x - 3.
We know the area of triangle is,
[tex]A = \frac{1}{2}*b*h[/tex] ; here A is the area, h is the height and b is the base.
Put the given values,
[tex]90 = \frac{1}{2} *(x)*(x-3)[/tex]
Multiplying both sides by 2:
180 = x² - 3x
x² - 3x - 180 = 0
(x - 15)(x + 12) = 0
Therefore, either x - 15 = 0 or x + 12 = 0.
If x - 15 = 0, then x = 15, which is the length of the base of the triangle.
If x + 12 = 0, then x = -12, which is not a valid solution since the length of a side of a triangle cannot be negative.
Therefore, the length of the base of the triangle is 15 feet.
The height of the triangle (x - 3), so the height is: (15 - 3) = 12 feet.
Hence, the length of the base is 15 feet and the height is 12 feet.

AP Environmental Science: Which of the following would be least likely to impact the price of electricity?
- price of a barrel of oil
- production of biodiesel
- cost of a ton of coal
- fire in a gas pipeline
The production of biodiesel would be the least likely to impact the price of electricity. Biodiesel is not commonly used as a fuel source for electricity generation, so changes in its production would not significantly affect the overall supply and demand of electricity. On the other hand, the price of a barrel of oil, the cost of a ton of coal, and a fire in a gas pipeline could all impact the price of electricity, as these are commonly used fuel sources for electricity generation.

Angles in a Triangle
Answer:
55
Step-by-step explanation:
The first we need to do is find the other angle measures. The left angle must be supplementary with 110, so it must measure 70. The right angle must be supplementary with 125, so it must measure 55. The sides of an angle add up to 180, so 180-70-55= 55
The angle of x is 55°.
There is 180° in a triangle. First, we need to calculate the angles of the other two sides. A straight line also forms 180°. Therefore the first angle will be
180 - 110= 70°
The second angle will be
180 - 125 = 55°
Angles of the triangle excluding x will be
70 + 55 = 125°
Since there is 180° in a triangle, x will be
180 - 125= 55°

Does point A on the graph represent a pair of possible values of m and w? Yes or no because 20 is or is not equal to 2.5 times 1.
Answer:
Yes, point A on the graph represents a pair of possible values of m and w because it satisfies the equation w = 2.5m + 5.
To confirm this, we can substitute m = 20 into the equation to get:
w = 2.5(20) + 5
w = 50 + 5
w = 55
So the coordinates of point A are (20, 55), which represents a possible value of m and w that satisfies the equation.
A glass contains 320 cm³ of milk. The mass of the milk is 330 g. Calculate the density of the milk in kilograms per cubic metre (kg/m³). Give your answer to the nearest integer.
If glass contains 320 cm³ of milk, the mass of the milk is 330 g, the density of the milk is approximately 1031 kg/m³.
Density is defined as the mass per unit volume of a substance. To find the density of milk in kg/m³, we need to convert the given volume and mass to the appropriate units.
First, we need to convert the volume from cm³ to m³. Since 1 m = 100 cm, 1 m³ = (100 cm)³ = 1,000,000 cm³. Therefore, we can convert 320 cm³ to m³ by dividing by 1,000,000:
320 cm³ ÷ 1,000,000 = 0.00032 m³
Next, we need to convert the mass from grams to kilograms. Since 1 kg = 1000 g, we can convert 330 g to kg by dividing by 1000:
330 g ÷ 1000 = 0.33 kg
Now that we have both the mass and volume in appropriate units, we can calculate the density by dividing the mass by the volume:
Density = mass ÷ volume = 0.33 kg ÷ 0.00032 m³ ≈ 1031 kg/m³

The value of arctan(√2) for the equation tan(x/2 - π/2) = √2 in the form x=π +πn is given by arctan(√2) = π/4 + πn, where n is an integer.
Equation is equal to,
tan(x/2 - π/2) = √2
By using the identity for tangent of half angle,
tan(x/2 - π/2)
= 1/cot(x/2 - π/2)
= 1/(-tan(x/2))
So the equation becomes,
1/(-tan(x/2)) = √2
Multiplying both sides by -1, we get,
tan(x/2) = -1/√2
= -√2/2
Now use the inverse tangent function (arctan) to find x/2,
arctan(-√2/2) = -π/4
Since x/2 - π/2 = -π/4, we have,
⇒ x/2 = -π/4 + π/2
= π/4
The solutions for x are x = π/2 + 2πn, where n is an integer.
Now let us find the value of arctan(√2),
arctan(√2) is the angle whose tangent is √2.
Since tan(π/4) = √2, we have,
arctan(√2) = π/4 + πn, where n is an integer.
Therefore, the value of arctan(√2) in the form x=π +πn is equal to

The solution of the system of equations is x = -5/17 and y = -16/17.
To do this, we can use a method called substitution. In this method, we solve one equation for one variable in terms of the other variable, and then substitute this expression into the other equation. This results in a new equation with only one variable, which can be solved to find the value of that variable. Once we know the value of one variable, we can substitute it into either equation to find the value of the other variable.
Let's apply this method to your system of equations:
5x - y/2 = -1 (Equation 1)
3x - 2y = 1 (Equation 2)
First, we'll solve Equation 1 for y in terms of x:
5x - y/2 = -1
y/2 = 5x + 1 (Add y/2 to both sides)
y = 10x + 2 (Multiply both sides by 2)
Now we substitute this expression for y into Equation 2:
3x - 2(10x + 2) = 1 (Substitute y = 10x + 2)
3x - 20x - 4 = 1
-17x = 5
x = -5/17
Now that we know the value of x, we can substitute it into either Equation 1 or Equation 2 to find the value of y. Let's use Equation 1:
5x - y/2 = -1
5(-5/17) - y/2 = -1
-25/17 - y/2 = -1
y/2 = -1 + 25/17

The area of the figure is 45 square millimeters.
What is Area?
Area is a measure of the size or extent of a two-dimensional surface or shape. It is usually expressed in square units such as square meters , square feet , square centimeters , square inches , etc. The area of a shape or surface can be calculated by multiplying the length of one side or dimension by the length of an adjacent side or dimension, or by using specific formulas depending on the shape.
The figure can be broken down into a rectangle (5 mm x 7 mm) and two right triangles (with legs 2 mm and 3 mm, respectively).
Area of rectangle = length x width = 5 mm x 7 mm = 35 square mm
Area of each triangle = 1/2 x base x height = 1/2 x 2 mm x 4 mm = 4 square mm
1/2 x 3 mm x 4 mm = 6 square mm
Total area of the figure = area of rectangle + area of two triangles = 35 square mm + 4 square mm + 6 square mm = 45 square mm.
Therefore, the area of the figure is 45 square millimeters.

A garden is in the shape of a square with a perimeter of 36 feet. The garden is surrounded by two
fences. One fence is around the perimeter of the garden, whereas the second fence is 2 feet from th
first fence on the outside. If the material used to build the two fences is $1.15 per foot, what was the
total cost of the fences?
The perimeter of the square garden is 36 feet, which means that each side of the square is 36/4 = 9 feet long. Therefore, the total cost of the fences is $92.
How is Perimeter calculated?The length of the outer fence, which is 2 feet away from the garden, is equal to the perimeter of a larger square with sides that are 2 feet longer than the sides of the original garden.
So, the length of the outer fence is 4(9+2) = 44 feet.
The length of the inner fence, which is around the perimeter of the garden, is equal to the perimeter of the original square garden, which is 4(9) = 36 feet.
The total length of both fences is the sum of the lengths of the inner and outer fences:
36 + 44 = 80 feet.
The cost of the fences is the total length of both fences multiplied by the cost per foot:
80 x $1.15 = $92.
Therefore, the total cost of the fences is $92.

f(x) = x² on [3, 3+h]
The average rate of change of the function f(x) = x² on the interval [3, 3 + h] is given as follows:
h + 6.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function.
The function in this problem is given as follows:
f(x) = x².
Then the outputs are obtained as follows:
f(3) = 3² = 9.f(3 + h) = h² + 6h + 9.The change in the output is given as follows:
h² + 6h + 9 - 9 = h² + 6h.
The change in the input is given as follows:
3 + h - 3 = h.
Hence the rate is:
r = (h² + 6h)/h.
r = h(h + 6)/h
r = h + 6.
