Hi this is my question "A certain expressway has rest áreas every 35 miles between cities. If city A is at mile marker 105 and city B is at mile marker 245, how many rest áreas will you pass between city A and City B. "​

In order to solve a matrix equation, the number of columns in the left matrix should be equal to the number of rows in the right matrix.

Therefore, the given matrix equation cannot be solved.

To solve the matrix equation \([0 -4 0 -1] X = [0 4]\), we need to find the value of the matrix X.

First, let's identify the dimensions of the matrices. The left matrix has dimensions 1x4 and the right matrix has dimensions 1x2.

Since the number of columns in the left matrix is not equal to the number of rows in the right matrix, this equation cannot be solved.

Answer:

y= 3x + 1

Step-by-step explanation:solve for y

subtract 3x from the left  which leaves -y= -3x -1

then you have to take flip the signs or divide by -1  so it comes out to y=3x + 1

Answer:

y = 3x + 1

Step-by-step explanation:

Slope Intercept form is written out as the following:

y = mx + b

In order to convert "3x - y = -1", we first subtract 3x from both sides, giving us:

-y = -3x - 1

Since we have "-y", we multiply -1 on both sides.

-1(-y) = -1(-3x - 1)

Multiplying two negatives makes a positive, hence when we multiply -1 on both sides, it becomes this:

y = 3x + 1

So converting to the Slope Intercept form ends up being "y = 3x + 1"

Subtraction:

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.

The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

The exponential model that calculates the concentration of bacteria after x weeks can be represented by the equation B(x) = 2.1 million * (3^x), the concentration after 1.6 weeks would be approximately 14.87 million bacteria per milliliter.

This equation assumes that the concentration triples each week, starting from the initial concentration of 2.1 million bacteria per milliliter.

To estimate the concentration after 1.6 weeks, we can substitute x = 1.6 into the exponential model. B(1.6) = 2.1 million * (3^1.6) ≈ 14.87 million bacteria per milliliter. Therefore, after 1.6 weeks, the estimated concentration of bacteria in the river would be approximately 14.87 million bacteria per milliliter.

The exponential model B(x) = 2.1 million * (3^x) represents the concentration of bacteria after x weeks, where the concentration triples each week.

The travel time x is 41.162 min such that 17.36% of the 60 days have a travel time that is at least x.

We have to determine the travel time such that 17.36% of the 60 days have a travel time that is at least.

Total work days to work = 60 days

The travel mean time = 35.6

Standard deviation = 10.3

For normal distribution,

P(X < A) = P(Z < (A - mean)/standard deviation)

P(X > x) = 0.2946

P(X < x) = 1 - 0.2946 = 0.7054

P(Z < (x - 35.6)/10.3) = 0.7054

Take the z value that corresponds to 0.7054 in the table of the standard normal distribution.

The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true). An alpha level of .01 means that there is a 1% chance of making a Type I error.

If Chastity ran a hypothesis test with an alpha level of .01 and her test statistic fell outside of the critical region, it means that the test statistic does not provide enough evidence to reject the null hypothesis.

In this case, Chastity should fail to reject the null hypothesis and accept it as the plausible explanation. This implies that there is not enough evidence to support the alternative hypothesis.

When a test statistic falls outside of the critical region, it indicates that the observed data is not extreme enough to reject the null hypothesis. The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true).

Answer:  20 liters

Step-by-step explanation:

The mixture is 60 liters. The ratio is 2 : 1   (2 parts to one part)

60 ÷ (2 + 1) = one part

60 ÷ 3 = 20

Therefore, the ratio of 2 : 1 means 2(20) liters milk to 1(20) liters water

If we change it to a ratio of 1 : 2, then we have 1(20) liters milk to 2(20) liters water.

2:1 ratio has 20 liters water

1:2 ratio has 40 liters water

The amount of water added is 40 - 20 = 20 liters

Step-by-step explanation:

these are 2 similar triangles, as due to the construction we have 3 corresponding pairs of equal angles (the 47° angle is a given as equal, then due to the rules of crossing lines the inner angles as S must be equal as opposite angles, and that automatically makes the third angles equal, as the sum of all angles in a triangle must be always 180°).

in similar triangles the length ratio of corresponding sides is the same for all corresponding sides and lengths in these triangles.

so, we can use the sides opposite of the 47° angles to find that ratio :

21/9 = 7/3

and now also the sides 28 and x must have the same ratio :

28/x = 7/3

4/x = 1/3

12/x = 1

(a) The function that models the number of mice after t years is m(t) = 340 * 2^t.

(b) The estimated mouse population after 6 years is 21,760.

(a) To find a function that models the number of mice after t years, we can use the exponential growth formula, which is given by:

m(t) = m₀ * 2^t

Where:

m(t) represents the number of mice after t years.

m₀ is the initial population of mice.

In this case, the initial population of mice is 340, so the function that models the number of mice after t years would be:

m(t) = 340 * 2^t

(b) To estimate the mouse population after 6 years, we can substitute t = 6 into the function:

m(6) = 340 * 2^6

m(6) = 340 * 64

m(6) = 21,760

Therefore, the estimated mouse population after 6 years is 21,760.

Nevertheless, since A and B can trade places inside their gathering in two unique manners (AB or BA), the genuine number of approaches to arrange four individuals in a row is 4! x 2.

Subsequently, the complete number of ways for five individuals, including A and B, to sit in a row at a movie theater if A and B must sit together is 4! x 2 = 48.

Initially, there are 5! ways to order 5 people in a row. That would be 120 ways. Now, we have A and B which must sit together. So, imagine that they form one group or entity, and now we have four people instead of five in the row. There are four people, and they can be arranged in 4! ways that would be 24 ways.The group of A and B can sit in two ways AB or BA. So, by placing AB as one entity, we have just two entities (AB and the remaining 3 people in the row) which can be arranged in 2 * 4! ways that would be 48 ways.
