Lacrosse players receive a randomly assigned numbered jersey to wear at games. If the jerseys are numbered 0−29, what is the probability the first player to be assigned a jersey gets #16
The probability that the first player to be assigned a jersey gets #16 is 0.0333 (or 1/30).
What is probability?
The probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%.
If there are 30 jerseys numbered 0-29 and they are all equally likely to be assigned, then the probability that the first player to be assigned a jersey gets #16 is 1/30 or approximately 0.0333 (rounded to four decimal places).
Hence, the probability that the first player to be assigned a jersey gets #16 is 0.0333 (or 1/30).

The golf ball is a sphere with a curved surface area of 57.217 sq cm. The number of dimples per sq. cm on the ball is D) 5.872.
In geometry, a sphere is a three-dimensional geometric shape that is perfectly symmetrical and round in shape. It is a set of points in space that are equidistant from a fixed center point. The surface of a sphere is made up of all the points that are at an equal distance, known as the radius, from the center.
Let's assume that the radius of the golf ball is r cm.
Given that
the circumference of the golf ball = 13.408 cm
2πr = 13.408
r = [tex]\frac{13.408}{2\Pi}[/tex]
r = [tex]\frac{13.408}{2\times3.142}[/tex]
r = 2.134 cm.
The radius of the sphere is 2.134 sq. cm.
The curved surface area of the sphere is 4πr².
CSA = 4πr²
CSA = 4 × 3.142 × 2.134²
CSA = 57.217 sq cm.
It is also given that there are 336 dimples on its surface.
Number of dimples per sq. cm = [tex]\frac{Total\ dimples\ on\ ball}{CSA}[/tex]

The equation for the total cost of using a computer for t minutes at the internet cafe is C = 0.80t + 3
The cost of using a computer at the internet cafe can be represented by a linear equation, where C is the total cost and t is the number of minutes used. The equation can be written as C = 0.80t + 3, where 0.80 is the cost per minute and 3 is the initial charge.
To make a table of values, we can plug in different values of t into the equation and solve for C
Number of Minutes (t) Total Cost to Use Computer (C)
0 C = 0.80(0) + 3 = 3
1 C = 0.80(1) + 3 = 3.80
2 C = 0.80(2) + 3 = 4.60
3 C = 0.80(3) + 3 = 5.40

The equation Az-b has a solution for all b precisely when it is a square matrix. G. none of the abovePrevious question
If A be a matrix with linearly independent columns, then the statement that must be true is (A) The equation Az=b always has a solution for all b.
Since the columns of A are linearly independent, the matrix A has full column rank, i.e., its column space is the entire space R^n. Here are the implications of this fact for each statement:
A. The equation Az=b always has a solution for all b.
This is true, because for any b in R^n, we can write it as a linear combination of the columns of A, say b=c_1a_1+c_2a_2+...+c_na_n. Then, the solution to Az=b is simply z=[c_1,c_2,...,c_n]^T.
B. The equation Ab has a solution for all b precisely when it has more rows than columns.
This statement is false. The equation Ab=b is always solvable, regardless of the dimensions of A and b. The solution is simply b expressed in the basis of the column space of A.
C. There is no easy way to tell if Ax-b has a solution for all b.
This statement is also false. Since the columns of A are linearly independent, the equation Ax=b has at most one solution for each b. Therefore, Ax=b has a solution for all b if and only if the columns of A span the entire space R^n. This can be checked by computing the rank of A.
D. The equation Az-b has a solution for all b precisely when it has more columns than rows.
This statement is false. The equation Az=b is always solvable, regardless of the dimensions of A and b, as we have seen in (A).
E. The equation Ax-b never has a solution for all b.
This statement is false. The equation Ax=b has at most one solution for each b, and it is solvable for all b if and only if the columns of A span the entire space R^n, as we have seen in (C).
F. The equation Az-b has a solution for all b precisely when it is a square matrix.
This statement is false. The equation Az=b is always solvable, regardless of whether A is square or not, as we have seen in (A).
Therefore, the only true statement among the given options is (A) The equation Az=b always has a solution for all b.

why does gyro never never ever bet on even numbers
Gyro never bets on even numbers because the expected value of such a bet is always negative.
To understand this concept, let's look at what an even number bet involves. When a person bets on an even number, they are essentially risking their entire stake on a 50/50 chance of winning.
This means that if they win, they will get their stake back plus the amount they would have won if the bet had been successful – in other words, their returns will be twice their original stake.
However, if they lose the bet, they will lose their entire stake. This means that the expected value of a bet on an even number is always negative. In other words, the expected outcome of the bet is always a loss.

The price of petrol is increased from R 12.58 per litre to R 13.28per litre Determine the percentage increase in the price
The percentage increase in the price of petrol is approximately 5.56%.
What is percentage?Percentages are used to compare and express parts of a whole, and to express changes or differences in values. For instance, we can use percentages to express:
A discount or a markup in prices
The increase or decrease in a quantity or value
The proportion of a quantity compared to a whole
The probability of an event occurring.
In the given question,
To determine the percentage increase in the price of petrol, we need to calculate the difference between the old price and the new price, divide that by the old price, and then multiply by 100 to convert to a percentage.
The difference between the old price and the new price is:
R 13.28 - R 12.58 = R 0.70
Dividing the difference by the old price:
R 0.70 ÷ R 12.58 ≈ 0.0556

If the base, b, is 6 inches, and the area, A, is 18 square inches, then the height, h, of the triangle is 6 inches.
What is triangle?Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.
The area of a right triangle can be found by using the formula A=1/2bh, where b is the base of the triangle and h is the height. In this example, the base, b, is 6 inches. To find the height, h, we can solve the equation for h: h = 2A/b, where A is the area of the triangle.
Therefore, if we know the area of the triangle, A, we can find the height, h, of the triangle by plugging in the values and solving for h. For example, if the area of the triangle is 18 square inches, then h = 2(18)/6 = 6 inches.
The area of a right triangle can be found by using the formula A=1/2bh and plugging in the known values of b and h. In this example, if the base, b, is 6 inches, and the area, A, is 18 square inches, then the height, h, of the triangle is 6 inches.

What separate the population into nonoverlapping groups?
Stratified Sampling separates the population into nonoverlapping groups. By using specific criteria to split the population, we may use this strategy to draw a proportional random sample from each division.
The population is divided into non-overlapping groups or strata, and a proportional simple random sample is taken from each stratum to create a stratified sample. Each group's members ought to have some things in common. We must choose the number of people to choose from each stratum after the strata have been established. Here, the proportionality of the chosen number is crucial. In order to make the characteristic of interest more homogeneous inside a stratum than between strata, strata are based on information other than the characteristic being measured that is known to or thought to fluctuate with the characteristic of interest. Hence, strata can be defined based on any property that explains variation in the characteristic of interest.
