Answer:

Step-by-step explanation:

Use notation x for the unknown variable:

Let the unknown number be x

Translate from words to math :

The sum of (add two things)

the cube of a number (x³) and (+)  the product (·) of the number (x) and 7

is equal to (=)  eight times(8·) the square of the number​(x²)

Write the mathematical equation:

x³+(x·7) = 8x²

Solve the equation to find x:

x³+7x = 8x², subtract 8x² from both sides

x³- 8x²+7x = 0, factor x

x(x²-8x+7) = 0, factor the quadratic equation (what 2 numbers have the sum 8, and product 7... numbers 1 and 7)

x(x-1)(x-7) = 0, find the roots (the solutions)

x= 0, x= 1, x= 7

Solution:

The equation given by the word problem is x³+7x = 8x²

The unknown number x, could be 0, 1, or 7

In probability theory, a Venn diagram is a diagrammatic representation of sets that shows all possible logical relations between them. Venn diagrams are widely used in probability and statistics to visualize the relationship between different sets of data.

The given Venn diagram shows the relationship between three sets, A, B, and C. In order to calculate probabilities using a Venn diagram, we need to know the number of elements or members in each set, as well as any overlapping regions.

We can then use these numbers to calculate the probability of different outcomes.Let's consider two possible probabilities from the given Venn diagram:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22. The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3The first probability can be calculated by dividing the number of elements in the overlapping region of sets A and B (which is 0.1) by the total number of elements in set B (which is 0.5).

This gives us a probability of 0.22 or 22%.The second probability can be calculated by dividing the number of elements in the union of sets B and C (which is 0.2) by the total number of elements in either set B or set C (which is 0.6). This gives us a probability of 1/3 or approximately 33%.

Therefore, the correct probabilities are:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22.

The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3

The value of z is approximately 1.28 (rounded to two decimal places).

To find the value of z such that 0.1 of the area lies to the right of z, we need to determine the z-value corresponding to the 90th percentile of the standard normal distribution. This can be achieved using a standard normal distribution table or statistical software.

In detail, the standard normal distribution has a mean of 0 and a standard deviation of 1. The area under the curve is standardized, allowing us to use z-scores to find percentiles. Since we want to find the z-value corresponding to the 90th percentile, we are looking for the value that leaves 10% of the area to the right. Using a standard normal distribution table or statistical software, we find that the z-value corresponding to the 90th percentile is approximately 1.28. Therefore, the value of z is approximately 1.28.

Without the standard deviation, we cannot calculate the standard error or the 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B.

To calculate a 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B, we can use the least squares means estimates provided in the JMP output.

According to the JMP output, the estimate for the mean time required to stabilize emergency condition 4 using display panel B is 10.375000.

To calculate the confidence interval, we need to find the margin of error. The margin of error can be calculated using the formula:

Margin of Error = Critical Value * Standard Error

In this case, we need to find the critical value for a 95 percent confidence interval. Since we have a sample size of 24 (as mentioned in the question), we can use the t-distribution with (24-1) degrees of freedom to find the critical value.

Looking up the critical value in the t-distribution table, with (24-1) degrees of freedom and a confidence level of 95 percent, we find that the critical value is approximately 2.064.

The standard error can be calculated using the formula:

Standard Error = Standard Deviation / √(sample size)

The standard deviation is not provided in the given information. Therefore, we cannot calculate the standard error or the confidence interval without this information.

In summary, without the standard deviation, we cannot calculate the standard error or the 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B.

Answer:

The answer I think it will be 24 but not sure.

Step-by-step explanation:

Answer:

The line crosses the x-axis at the point (-3.5,0).

The expression that best models the population of the herd is:

y = (34/5)x - 558, where y is the population of the herd, and x is the time in years since 2010.

To model the population of the bison herd as a linear function of time, we can use the slope-intercept form of a linear equation, which is y = mx + b, where y is the population of the herd, x is the time in years since 2010, m is the slope of the line, and b is the y-intercept of the line.

To find the slope of the line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) is the point (2010, 122), and (x2, y2) is the point (2015, 156).

m = (156 - 122) / (2015 - 2010) = 34 / 5

So the slope of the line is 34/5.

To find the y-intercept of the line, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

where (x1, y1) is the point (2010, 122), and m is the slope we just found.

y - 122 = (34/5)(x - 2010)

y - 122 = (34/5)x - 13668

y = (34/5)x - 13546

a. The probability of an odd number, then drawing a 6 is 3/16

b. The probability of a 2, then drawing another 2 is 1/12

c. The probability of a number divisible by 3, then drawing a 1 is 1/8

d. The probability of a 1, then drawing a 6 is 1/24

e. The probability of a prime number, then drawing a composite number is 1/8

f. The probability of drawing another 9 is 1/24

g. The probability of drawing a 9, then drawing a number divisible by 1 is 1/14

h. The probability of this event occurring is 3/56.

Given board game numbers:

2 1 6 2

9 6 6 1

We can find the probability of each event by using the following formula:

P(A and B) = P(A) × P(B|A)

where P(A) is the probability of event A occurring, and P(B|A) is the conditional probability of event B occurring given that event A has occurred.

a. An odd number, then drawing a 6:

P(Odd number) = 3/8 (since there are 3 odd numbers out of 8 total numbers)

P(Drawing a 6 given an odd number) = 1/2 (since only 2 and 6 are left after drawing the odd number)

P(Odd number and drawing a 6) = P(Odd number) × P(Drawing a 6 given an odd number) = (3/8) × (1/2) = 3/16

b. A 2, then drawing another 2:

P(Drawing a 2) = 2/8 = 1/4

P(Drawing another 2 given the first draw was 2) = 1/3 (since only two 2's are left after the first draw)

P(Drawing 2 and then another 2) = P(Drawing a 2) × P(Drawing another 2 given the first draw was 2) = (1/4) × (1/3) = 1/12

c. A number divisible by 3, then drawing a 1:

P(Number divisible by 3) = 2/8 = 1/4

P(Drawing a 1 given a number divisible by 3) = 1/2 (since only 1 and 6 are left after drawing a number divisible by 3)

P(Number divisible by 3 and drawing a 1) = P(Number divisible by 3) × P(Drawing a 1 given a number divisible by 3) = (1/4) × (1/2) = 1/8

d. A 1, then drawing a 6:

P(Drawing a 1) = 1/8

P(Drawing a 6 given the first draw was 1) = 1/3 (since only two 6's are left after the first draw)

P(Drawing a 1 and then a 6) = P(Drawing a 1) × P(Drawing a 6 given the first draw was 1) = (1/8) × (1/3) = 1/24

e. A prime number, then drawing a composite number:

P(Prime number) = 2/8 = 1/4

P(Drawing a composite number given the first draw was prime) = 3/6 (since there are three composite numbers left after drawing a prime number)

P(Prime number and then a composite number) = P(Prime number) × P(Drawing a composite number given the first draw was prime) = (1/4) × (3/6) = 1/8

f. A 9, then drawing another 9:

P(Drawing a 9) = 1/8

P(Drawing another 9 given the first draw was 9) = 1/3 (since only two 9's are left after the first draw)

P(Drawing a 9 and then another 9) = P(Drawing a 9) × P(Drawing another 9 given the first draw was 9) = (1/8) × (1/3) = 1/24

g. The probability of drawing a 9 on the first draw is 1/8, as there is only one 9 out of eight numbers in the set.

Given that a 9 was drawn on the first draw, the probability of drawing a number divisible by 1 on the second draw is 4/7, since there are four numbers (2, 1, 6, and 9) that are divisible by 1 out of the seven remaining numbers in the set.

Therefore, the probability of drawing a 9 on the first draw and a number divisible by 1 on the second draw is:

P(9, divisible by 1) = P(9) * P(divisible by 1 | 9 was drawn)

= (1/8) * (4/7)

= 1/14

h. An even number, then drawing a 1

To find the probability of drawing an even number first and then drawing a 1, we need to consider the following events:

Drawing an even number: There are three even numbers in the set {2, 1, 6, 2, 9, 6, 6, 1}, so the probability of drawing an even number is 3/8.

Drawing a 1: There is only one 1 in the remaining set of seven numbers after the first draw, so the probability of drawing a 1 after drawing an even number is 1/7.

Therefore, the probability of drawing an even number first and then drawing a 1 is:

P(even number, then 1) = P(even number) × P(1 after even number)

= (3/8) × (1/7)

= 3/56

Any arrangement of portions or pieces of similar sizes can symbolize a whole. Standard English refers to quantity as "a fraction" in a specified measure. 8, 3/4. Wholes also include fractions. The ratio of the divisor compared to the ratio is used in mathematics to represent numbers. These are all illustrations of fundamental fractions that split by whole numbers.

Here,

You must identify a common denominator for the two fractions in order to subtract fractions with distinct denominators.

Finding the least common multiple (LCM), which is 15 for the denominators 5 and 3, is one approach to accomplishing this.

After that, you can change both numbers so that their numerator is 15:

=> 4/5 = (4/5) x (3/3) = 12/15

=> 2/3 = (2/3) x (5/5) = 10/15

Since both fractions now have the same denominator, you can simplify the sum by removing their numerators:

=> 12/15 - 10/15 = 2/15

Because of this, 4/5 - 2/3 equals 2/15.
