The inequality which can be used to determine amount the club needs to raise during remaining months is 400 + 4n ≥ 750.

The goal of the school chess club is to raise at least $750 in total so that they can attend a state competition. They have already raised $400, but they still need to raise more money. Let's call the amount they need to raise each month "n".

Since the club has 4 months remaining until the competition, they will need to raise a total of "4n" dollars during that time period.

To determine the minimum amount they need to raise each month, the inequality can be written as : 400 + 4n ≥ 750,

4n ≥ 350 ; n ≥ 87.5.

This means that the chess-club needs to raise at least $87.50 each month in order to reach their goal of $750 in 4 months.

Therefore, the required inequality is 400 + 4n ≥ 750.

The toy cars Anna must sell for her revenue to equal her expense is 4 toy cars. The result is obtained by using the concept of calculating algebra.

To calculate the algebra with one variable, sum up all the same variable and count the value.

Anna want to sell toy car at a craft fair. Each car is sold at a price of $ 12. The material for each car cost $ 3.50 and the table rental at the fair is 34 dollar for the day.

Find the toy cars must Anna sell for her revenue to equal her expense!

We have

Let's say

Revenue = Expense

a × $12 = (a × $3.5) + $34

12a = 3.5a + 34

12a - 3.5a = 34

8.5a = 34

a = 4 toy cars

Hence, Anna must sell 4 toy cars so that her revenue is equal to expense.

Answer:

Step-by-step explanation:

The number of hours it would take the bacteria counts to reach one million is approximately 10.96 hours.

The formula can give the number of bacteria in the culture;

n(t)=n0 2t/4.The value of 'n0' is 15.

Therefore,

n(t)= 15 × 2t/4

= 15 × 22t× 1/4

= 15 × 22t/4

= 15 × 22t/4

The estimate of the number of bacteria after 19 hours would be given by;

n(19)= 15 × 22 × 19/4

= 15 × 262144/16

= 393216/16

≈ 24576

We can begin by setting up the exponential model as;

n(t)=n0 2t/4 and then plug in the values;

n(t)=n0 2t/4

= 15 × 2t/4≥ 1000000

Multiplying by 4 on both sides, we get;

2t≥ 4(6+log2 5) t≥ 3(6+log2 5) /2

= 10.96

Therefore, the number of hours it would take the bacteria count to reach one million is approximately 10.96 hours.

To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.

Starting cash balance: $4,520

Cash inflows: $1,654 (receivables collected)

Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)

Total cash inflows: $1,654

Total cash outflows: $1,961 + $500 = $2,461

To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:

Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows

Cash balance at the end of the period = $4,520 + $1,654 - $2,461

Cash balance at the end of the period = $4,520 - $807

Cash balance at the end of the period = $3,713

1 = 4 so each are 125 degrees

We know that horizontal lines equal 180 degrees so:

125 + angle 3 = 180

180 - 125 = angle 3

angle 3 = 55

angle 3 = angle 2

so angle 2 is 55 as well

If we look at the angles below, they are the exact same as the angles above, therefore we can say that:

1 = 4 = 5 = 8

2 = 3 = 6 = 7

angle 6 and 7 = 55

The correlation coefficient measures the relationship between variables. Statistical significance determines if a difference is meaningful. Frequency represents distribution, and range measures variability in data.

It quantifies the strength and direction of the linear relationship between two variables. The correlation coefficient ranges from -1 to +1, where -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 indicates no linear correlation between the variables.

Statistical significance refers to the likelihood that an observed difference or relationship between variables in a sample is not due to random chance but reflects a true difference or relationship in the population. It is assessed using hypothesis testing and p-values. If the p-value is below a predetermined significance level (often 0.05), the difference or relationship is considered statistically significant.

The frequency of scores at each level of some measure refers to the number of times each value or category occurs in a dataset. It provides information about the distribution of scores and allows us to understand the prevalence of different values or categories within the data.

The difference between the highest and lowest scores in a distribution is known as the range. It is a simple measure of dispersion that provides an indication of the spread or variability of the data. It is calculated by subtracting the lowest score from the highest score.

The distance between points M(6, 16) and Z(-1, 14) is approximately 7.1 units.

We can use the distance formula to find the distance between two points in a coordinate plane. The distance formula is:

d = √((x2 - x1)² + (y2 - y1)²)

where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the coordinates of M(6, 16) and Z(-1, 14), we get:

d = √((-1 - 6)² + (14 - 16)²) = √(49 + 4) = √53 ≈ 7.1

Step-by-step explanation:

y = 3x - 2 → (1)

y = - 2x + 3 → (2)

substitute y = 3x - 2 into (2)

3x - 2 = - 2x + 3 ( add 2x to both sides )

5x - 2 = 3 ( add 2 to both sides )

5x = 5 ( divide both sides by 5 )

x = 1

Answer:

(1,1)

Step-by-step explanation:

The question is asking if there is a point, (x,y), that satisfies (works) for both equations.  Is there a combination of x and y that works in both.

We can solve this in one of two ways:  mathematically and graphically.  If the lines intersect, then they will have the one common value of (x,y).

Mathematically:

y = 3x − 2  

y = -2x + 3

Set them equal to each other (i.e., y = y)

3x − 2 = -2x + 3

5x = 5

x = 1

Use this value of x in either equation to find y:

y = 3x − 2

y = 3(1) − 2

y = 1

The common point is (1,1)

Graphically:

Plot the two lines and look for the intersection point.  See attached.

a) The z-score corresponding to the probability of 0.2000 to the right is z = 0.84.

b) The z-score corresponding to the probability of 0.9000 to the left is z = -1.28.

a) To find the z-score corresponding to a probability of 0.2000 to the right, we need to use the fact that the area under the standard normal distribution to the right of z is equal to 1 minus the area to the left of z.

In other words, we need to find the z-value such that the area to the left of it is equal to 1 - 0.2000 = 0.8000. Consulting a standard normal distribution table or using a calculator, we find that this z-value is approximately 0.84. Therefore, the answer is z = 0.84.

b) Similarly, to find the z-score corresponding to a probability of 0.9000 to the left, we need to find the z-value such that the area to the left of it is equal to 0.9000. Consulting a standard normal distribution table or using a calculator, we find that this z-value is approximately 1.28. Therefore, the answer is z = -1.28.

In both cases, we used the fact that the standard normal distribution has a mean of 0 and a standard deviation of 1, and we transformed the probability into an area under the curve.
