Final answer:
The probability of Tim teeing off with a white ball and putting with an orange ball is 0.0331. The events are dependent.
Explanation:
To calculate the probability of Tim teeing off with a white ball and putting with an orange ball, we need to consider the total number of balls in the bag and the number of white and orange balls.
There are a total of 9 white balls, 6 yellow balls, 1 orange ball, and 1 pink ball in the bag. The probability of Tim teeing off with a white ball is 9 out of 17, since he can choose any of the 9 white balls out of the total 17 balls. After Tim tees off with a white ball, there are now 8 white balls left in the bag.
Next, Tim needs to putt with an orange ball. The probability of Tim putting with an orange ball is 1 out of 16, since there is 1 orange ball left in the bag and a total of 16 balls.
To find the probability of both events happening, we multiply the two probabilities:
P(white, then orange) = P(white) × P(orange|white) = 9/17 × 1/16 = 9/272 = 0.0331 (rounded to four decimal places).
The events of teeing off with a white ball and putting with an orange ball are dependent events, as the outcome of the first event affects the probability of the second event.

To play basketball with her friends, Evangeline needs to pump air in her ball, which is completely deflated. Before inflating it, the ball weighs 0.615 kilograms. Afterwards, it weighs 0.624 kilograms. The diameter of the ball is 0.24 meters.Assuming the inflated ball is perfectly spherical, what is the air density within it.
Answer:
1.24 kilograms per cubic meter.
Step-by-step explanation:
The air density is "[tex]1.24\ \frac{kg}{m^3}[/tex]"
Air density:The initial weight of 7 ball [tex]= 0.615 \ kg\\\\[/tex]
weight of 7 inflated balls[tex]= 0.624 \ kg\\\\[/tex]
Calculating the mass (weight) of 7 air:
[tex]\to 0.624-0.615\ kg\\\\ \to 0.009\ kg\\\\[/tex]
Calculating the diameter of 7 balls:
[tex]\to 0.24 \ m\\\\[/tex]
Calculating the Radius of the ball:
[tex]\to \frac{\text{diameter}}{2}\\\\ \to \frac{0.24}{2}\\\\ \to 0.12\ m\\\\[/tex]
Calculating the volume of air in the ball:
[tex]\to \frac{4}{3} \pi r^3\\\\\to \frac{4}{3} \pi (0.12)^3 \\\\ \to 1.333333 \times 3.14 \times 0.001728 \\\\ \to 0.00723456\\\\[/tex]
Calculating the density of air:
[tex]\to \text{Air density}=\frac{\text{Mass}}{\text{volume}}\\\\[/tex]
[tex]=\frac{ 0.009}{0.00723456}\ \frac{kg}{m^3}\\\\ =1.244\ \frac{kg}{m^3} \\\\=1.24\ \frac{kg}{m^3}[/tex]
Therefore, the air density is "[tex]1.24\ \frac{kg}{m^3}[/tex]".

The scores of individual students on the American College Testing (ACT) Program composite college entrance examination have a normal distribution with mean 18.6 and standard deviation 6.0. At Northside High, 36 seniors take the test. If the scores at this school have the same distribution as national scores.
(a) What is the mean of the sampling distribution of the sample mean score for a random sample of 36 students?(b) What is the standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students?(c) What is the sampling distribution of the sample mean score for a random sample of 36 students?
Answer:
a. mean=18.6
b. standard deviation=1.0
c. The distribution is a symmetry and mound-shaped but nowhere near normal.
Step-by-step explanation:
a. let [tex]\mu_x[/tex] be the sample mean.
-For a normal distributed sample, the population mean is equal to the sample mean:
[tex]\mu_x=\mu\\\\=18.6[/tex]
Hence, the sample mean is 18.6
b. Let s denote the sample standard deviation.
-For a normally distributed population, the sample standard deviation is calculated using the formula;
[tex]s=\frac{\sigma}{\sqrt{n}}\\\\=\frac{6}{\sqrt{36}}\\\\=1.0[/tex]
Hence, the sample standard deviation is 1.0
c. The sample has a mean of 18.6 and a standard deviation of 1.0
-Since it's derived from a normally distribted population, it will be symmetrical and have an almost normal shape.
-Hence, it is a symmetry and mound-shaped, but Not Normal.
The mean of the sampling distribution is 18.6. The standard deviation of the sampling distribution is 1.0. The sampling distribution of the sample mean score for a random sample of 36 students is normally distributed with a mean of 18.6 and standard deviation of 1.0, according to the central limit theorem.
Explanation:The mean and standard deviation of the population, which are given as 18.6 and 6.0 respectively, are used to calculate the mean and standard deviation of the sampling distribution.
(a) According to the central limit theorem, the mean of the sampling distribution of the sample mean score for a random sample of 36 students (µx-bar) is equal to the mean of the population (µ), so µx-bar = µ = 18.6.
(b) The standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students (σx-bar) is the standard deviation of the population (σ) divided by the square root of the sample size (n), so σx-bar = σ/√n = 6.0/√36 = 1.0.
(c) The sampling distribution of the sample mean score for a random sample of 36 students is a normal distribution with mean µx-bar = 18.6 and standard deviation σx-bar = 1.0, according to the central limit theorem, since the sample size is sufficiently large (n > 30).

The population of Atlanta is 5,949,951. It is said to be growing at a rate of 1.3% yearly. What will the population be in 10 years? *
Answer:
6770299
Step-by-step explanation:
To work this out you would first divide 1.3 by 100, which gives you 0.013. Then you would add 0.013 to 1, which gives you 1.013. This is because you are finding a percentage increase and so you would convert the percentage to a decimal and add it to 1. Then you would multiply 5949951 by 1.013 to the power of 10. This is because you are finding the percentage increase over a span of 10 years.
1) Divide 1.3 by 100.
[tex]1.3/100=0.013[/tex]
2) Add 0.013 to 1.
[tex]0.013+1=1.013[/tex]
3) Multiply 5949951 by 1.013 to the power of 10.

Does a rectangle have four congruent sides?
Answer:
NO.
Step-by-step explanation:
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. So, in other words, 2 shapes or figures in geometry are congruent if they have the exact same size and shape.
A rectangle has 2 pairs of parallel sides. One pair is longer than the other pair. Therefore, to be congruent, all sides have to be equal, which is a square, not a rectangle. So the answer is NO.
No a rectangle does not have four congruent sides instead it has two pairs of congruent sides.
A rectangle has two pairs of congruent sides that are opposite each other. Therefore, a rectangle does not have four congruent sides, but rather two pairs of congruent sides.

Makayla charges 20 cents per square inch for her frame. How much will she charge for a frame that measures 18 inches on each side and has a width of 3 inches ?
Answer:
The answer is $10.8 (1,080 cents)
Step-by-step explanation:
First of all, let us calculate the area of the frame:
Area = Length × width = 18 × 3 = 54 in²
We are told that she charges 20 cents per square inch, therefore:
1 in² = 20 cents
∴ 54 in² = 20 × 54 = 1,080 cents.
We know that 100 cents = $1
∴ 1,080 cents = 1/100 × 1,080 = $10.8

Why were some economists unsure of how to fight stagflation?
It only needs to be about a sentence.
Answer:
Stagflation is the combination of stagnation and inflation. Its simply mean continues increase in inflation while consumer demand for product is stagnant and there is relatively high unemployment
Reason;
Some economist hold that inflation is caused when demand for goods are high and demand for a product can not be controlled where there is no price regulation.
Answer: The reason was because Economists at that time believed that inflation only occurred when the demand for goods was high.
Step-by-step explanation:
Stagflation occurred in the 1970's in the United States under the rule of President Gerald R. Ford. Stagflation is a term used to describe a situation of both stagnation and inflation in the economy. The period was a tough time in the history of America. It occurred just after the tenure of President Johnson who contributed to the crisis through his policy of pumping money into the economy to increase spending without increasing taxes. The resultant effect of this was inflation.
America was also dependent on oil at that time, even though the price of oil was rapidly increasing. The period saw them importing more goods than exporting. Also, jobs were lost. Economists tried to solve the issue but it was difficult because they believed that inflation could only occur when the demand for goods was high.

What are the surface area and volume ratios of a cylinder change if the radius and height are multiplied by 5/4 ?
Answer:
The ratio of the surface areas and volume is 8((5y+5x) /25xy)
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes.
Let us assume that the radius =x
Radius r=5x/4
And the height =y
Height h= 5y/4
We know that the total surface area of a cylinder is
A total = 2πrh+2πr²
We can factor out 2πr
A total = 2πr(h+r)
The volume of a cylinder is given as
v= πr²h
The surface area and volume ratios
Can be expressed as
2πr(h+r)/πr²h= 2(h+r)/rh
= (2h+2r)/rh= 2h/rh + 2r/rh
= 2/r + 2/h
= 2(1/r + 1/h)
Substituting our value of x and y
For radius and height we have
= 2(1/5x/4 + 1/5y/4)
=2(4/5x + 4/5y)
=2*4(1/5x + 1/5y)
= 8 (5y+5x/25xy)
Answer:
Ratio of surface area = 25/16
Ratio of volume = 125/64
Step-by-step explanation:
The surface area and volume of a cylinder are given by the formulas:
Surface area = 2*(pi*r^2 + pi*r*h)
Volume = pi*r^2*h
If we increase the radius and height by 5/4, we have that:
New surface area = 2*(pi*(5/4*r)^2 + pi*(5/4)*r*(5/4)*h) = (5/4)^2 * 2*(pi*r^2 + pi*r*h) = (5/4)^2 * Surface area
New volume = pi*(5/4*r)^2*(5/4)*h = (5/4)^3 * pi*r^2*h = (5/4)^3 * Volume
So the ratios are:
ratio of surface area = New surface area / Surface area = (5/4)^2 = 25/16
ratio of volume = New volume / Volume = (5/4)^3 = 125/64

A=3.14*0.025²
A=0.0019m²
To 3 dp we have area as 0.002m²
Tell if the measures 10, 12, and 16 can be the side lengths of a triangle. If so, classify the triangle as acute, obtuse, or right.
Answer:
Yes, acute
Step-by-step explanation:
Because 10 and 12 add up to more than 16, it is possible to construct an acute triangle with these side lengths. Since 10^2 + 12^2 ≠ 16^2, we know that any triangle so constructed will not be a right triangle.
The measures 10, 12, and 16 can be the side lengths of a triangle because the sum of the two shorter sides must be greater than the longest side for a triangle to exist.
In this case, 10 + 12 is greater than 16, 16 + 10 is greater than 12, and 12 + 16 is greater than 10, satisfying the triangle inequality theorem. Therefore, a triangle can be formed.
Classifying the triangle: Using the Pythagorean theorem, we can determine that the triangle with side lengths 10, 12, and 16 is a scalene triangle, and since 10^2 + 12^2 is less than 16^2, it is an obtuse triangle.

find the area of a regular octagon with a perimeter of 96 centimeters
Answer:
A≈695.29cm²
Step-by-step explanation:
The area of a regular octagon with a perimeter of 96 cm is calculated by first finding the length of one side, then calculating the area of one of the eight isosceles triangles formed within the octagon, and finally multiplying this area by eight to get the total area, which is 384 cm².
To calculate the area of a regular octagon with a given perimeter, we first need to determine the length of one side. Since a regular octagon has equal sides, we can divide the perimeter by 8. In this case, the perimeter is 96 centimeters, so each side of the octagon is 96 cm / 8 = 12 cm.
We know that a regular octagon can be divided into eight identical isosceles triangles. The area of an isosceles triangle can be found by the formula A = (1/2)bh, where b is the base and h is the height.
To find the height of each triangle, we can draw an altitude from the center of the octagon to the base of one of the triangles, which creates two 90-degree triangles.
By using the Pythagorean theorem on one of these right-angled triangles, with the base of each being half the length of an octagon's side (6 cm), and the Pythagorean triple 6-8-10, we can determine the height to be 8 cm. Thus, the area of each triangle is (1/2) * 12 cm * 8 cm = 48 cm².
Finally, since there are eight triangles, the total area of the octagon is 8 * 48 cm² = 384 cm².
