The probability that at least 1000 cars will cross the intersection in the next hour depends on the assumptions made about the distribution of car arrivals.

The probability that at least 1000 cars will cross the intersection in the next hour can be determined by first finding the rate per hour.
Convert the rate from cars per minute to cars per hour.

Since there are 60 minutes in an hour, multiply the given rate (16 cars per minute) by 60 minutes:
16 cars/minute x 60 minutes/hour = 960 cars/hour
Compare the desired number of cars (1000) with the calculated rate per hour (960 cars/hour). Since 1000 cars are more than the rate of 960 cars/hour, the probability of at least 1000 cars crossing the intersection in the next hour is less than 100%.
To determine the exact probability, we need to make some assumptions about the distribution of car arrivals.

If we assume the car arrivals follow a Poisson distribution, we can use the Poisson probability formula to find the probability of at least 1000 cars crossing the intersection:
P(X ≥ 1000) = 1 - P(X < 1000) = 1 - (P(X=0) + P(X=1) + ... + P(X=999))
Where P(X=k) = (e^(-λ) * (λ^k)) / k!,

λ is the average rate (960 cars/hour), and k is the number of cars.
Calculate the probabilities for P(X=0) to P(X=999) and sum them up.

Then subtract the sum from 1 to get the probability of at least 1000 cars crossing the intersection in the next hour.

Answer: i think c

Step-by-step explanation:

The following statements are true:

The product "ax" is defined when "x" is a 1 x n vector, provided the dimensions of the matrix "a" and the vector "x" are compatible. For the product to be defined, the number of columns in "a" must equal the number of rows in "x".

The matrix equation "ax = b" has a unique solution for "x" if and only if the matrix "a" is non-singular, meaning that its determinant is non-zero. If "a" is non-singular, then the inverse of "a" exists and can be used to solve for "x" using the formula "x = a^(-1)b". If "a" is singular, then the equation "ax = b" is either inconsistent (i.e., has no solution) or has infinitely many solutions.

So, both options are true.

Answer:

A. x ≤ -2 or x > 3

Step-by-step explanation:

The number line shows two possible values of x which represents a compound inequality.

There are two arrows in opposite direction on the number line.

The arrow that starts at -2 and goes to your far left, has a shaded small circle "o". This connotes that -2 is included in the possible values of x. Thus, this means the possible value of x is equal to -2 or less than -2 ==> x ≤ -2.

The other arrow starts at 3 and has an unshaded small "o", implying that 3 is not included in the possible values of x. Thus, x > 3.

The compound inequality in the graph indicates either statement is true, since each solution do not overlap, hence, the word to use here would be "OR", showing a union.

Therefore, the solution of the compound inequality would be x ≤ -2 or x > 3.

By definition of linear independence, the vectors in the set {a, b, c} are independent if

\(k_1\vec a+k_2\vec b+k_3\vec c=\vec0\)

can only be obtained with the choice of k₁ = k₂ = k₃ = 0.

This vector equation corresponds to the system of linear equations

\(\begin{cases}k_1 - 2k_3 = 0 \\ 2k_1 + k_2 = 0 \\ k_1 + 2k_3 = 0\end{cases}\)

The first equation says k₁ = 2 k₃, while the third one says k₁ = -2 k₃. This can only be possible if k₁ = k₃ = 0, and from the second equation it follows that k₂ = 0. So the given set is linearly independent (and *not* dependent).

Therefore, the longest length of pencil that John can hide in the pencil holder is approximately 127.32 cm (rounded to two decimal places).

Given that John has a 100 cm³ pencil holder, the longest length of pencil he can hide in the pencil holder can be found by using the formula for the volume of a cylinder which is given by: V = πr²h where r is the radius of the cylinder and h is the height of the cylinder.The volume of a cylinder can also be expressed as V = lwh where l is the length of the cylinder, w is the width of the cylinder and h is the height of the cylinder.

If we assume that the pencil is cylindrical in shape, then its volume can be given by V = πr²l where r is the radius of the pencil and l is the length of the pencil.Since the volume of the pencil holder is given to be 100 cm³, then we have:100 = πr²h (Equation 1)

Now, we need to find the value of l that can fit inside the pencil holder. We can use the formula for the volume of the pencil to do this as follows:

V = πr²lLet V = 100 cm³ and

r = 0.5 cm

(since the pencil holder is cylindrical in shape, we can assume that it has a radius of 0.5 cm)Then, we have:100 = π(0.5)²lSolving for l, we get:

l = 100 / (π(0.5)²)

l = 100 / (0.7854)l ≈ 127.32 cm

The basic idea in solving equations is to undo what is done to the variable. The "undo" operation is the inverse operation. Addition is undone by subtraction (and vice versa); division is undone by multiplication (and vice versa).

The Order of Operations can give you a clue as to the operations and the sequence required. When you evaluate the expression with the varialbe, here you add 2.3, then divide the sum by 5.8.

These operations are undone in reverse order: first you multiply by 5.8, then you subtract 2.3.

Sometimes, you need to simplify the equation (remove parentheses and combine like terms, for example) before you start. Sometimes you don't.

The range is the set of all possible y-values that could come from the equation y = |x|.

Since the absolute value only results in 0 or positive numbers, the range cannot include any negative real numbers.  

    |3| = 3

    |0| = 0

    |-3| = 3

Therefore the range is not all real numbers, since all negative real numbers are excluded from the range.

The range is y ≥ 0.

The quotient of 550six and 50six​ is obtained by the calculation to be   11 six

We know that the result that we obtain after we have carried out a division operation is called a quotient. In this case, we have been required to carry out the operation of division in base six.

We could start by converting the both values to base 10 as follows;

(5 * 6^2) + (5 * 6^1) + (0 * 6^0) = 180 + 30 + 0 = 210 ten

(5 * 6^1) + (0 * 6^0) = 30 + 0 = 30 ten

Then we carry out the division in base ten; 210 ten/30 ten = 7 ten

We convert back to base six to obtain 11 six

The amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service

Given that, a woman bought 1.8 kg of chicken and 1.6 kg of meat. The chicken cost $5.40 and the meat cost $6.40,

We need to find, if she had bought 2.4 kg of chicken and 2 kg of meat, how much would she have had to pay,

To find the same, we will first find the unit price of each,

Unit price = total price / total quantity

Since, 1.8 kg of chicken costs $5.40,

Therefore, 1 kg will cost = 5.40 / 1.8 = $3

Similarly,

If 1.6 kg of meat costs $6.40,

Therefore, 1 kg will cost = 6.40 / 1.6 = $4

Now, to find the cost of 2.4 kg of chicken and 2 kg of meat, we will multiply the unit prices to the required quantities,

Therefore,

2.4 kg of chicken will cost = 2.4 x 3 = $7.2

2 kg of meat will cost = 2 x 4 = $8

In total, she had to pay = 8+7.2 = $15.2

Hence, the amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The x-coordinates where the graphs of the equations intersect are x = -1 and x = 3

From the question, we have the following parameters that can be used in our computation:

y = 2x

y = x² - 3

The x-coordinates where the graphs of the equations intersect is when both equations are equal

So, we have

x² - 3 = 2x

Rewrite the equation as

x² - 2x - 3 = 0

When the equation is factored, we have

(x + 1)(x - 3) = 0
