From the question, the sum of each of the geometric sequence are;

1)  31 3/4

2) 340

3) 11/16

4) -6, 12, -24

We have that;

Sn = a(1 -\(r^n\))/1 - r

Sn = 16(1 \(- (1/2)^7\))1 - 1/2

Sn = 16(1 - 1/128)/1/2

Sn = 16(127/128) * 2

Sn = 31 3/4

2) Un = a\(r^n\) -1

256 = \(4(4)^n-1\)

64 =\(4^n-1\)

\(4^3 = 4^n-1\)

n = 4

Sn= \(4(4^4 - 1)\)/4 - 1

Sn = 340

3) Since we have a5 then n = 5

Sn = 1(1 - (\(-1/2)^5\))/1 -(-1/2)

Sn = 33/32 * 2/3

= 11/16

4) 30= a(1 -\((-2)^4\))/1 - (-2)

30 = a(-15)/3

30 = -5a

The maximum number of glasses that can fit between two shelves in Monica's kitchen cabinet is 4.

option B.

To find the maximum number of glasses that can fit between two shelves, we need to subtract the height of two stacks of glasses from the distance between the shelves and divide by the height of a single stack.

Let's call the height of a single glass "h".

Then the height of a stack of 8 glasses would be 8h, and the height of a stack of 2 glasses would be 2h.

We know that:

8h = 42 cm

2h = 18 cm

So,

h = 42 cm / 8

h = 5.25 cm

And,

h = 18 cm / 2

h = 9 cm

Now, we can calculate the maximum number of glasses that can fit between two shelves as follows:

= ( 36 cm - 42 cm - 18 cm ) / 5.25 cm

= ( 36 cm - 60 cm ) / 5.25 cm  

= -24 cm / 5.25 cm

= -4.5 stacks

Since a stack must have a whole number of glasses, we can conclude that the maximum number of glasses that can fit between two shelves in Monica's kitchen cabinet is 4.

The confidence interval would become narrower if the confidence level had been 95% instead of 98%. The sample size would need to be quadrupled to make the margin of error half as big in the 98% confidence interval.

a. If the confidence level had been 95% instead of 98%, the confidence interval would become wider. A higher confidence level requires a wider interval to capture a larger range of possible values.

b. To make the margin of error half as big in the 98% confidence interval, we would need to quadruple the sample size. The margin of error is inversely proportional to the square root of the sample size. Therefore, to reduce the margin of error by half, we need to increase the sample size by a factor of 4.

In the given scenario, we have a survey of 180 students with a confidence interval of (0.413, 0.587) at a 98% confidence level. If we wanted to decrease the margin of error by half, we would need a sample size four times larger than the original sample. This means we would need a sample size of 720 students to achieve a 98% confidence interval with half the margin of error.

In summary, changing the confidence level affects the width of the confidence interval, and to make the margin of error half as big, the sample size needs to be quadrupled.

Answer:

fish that are caught and tagged by the research teams

Step-by-step explanation:

The measures of triangle exists 45 45 90 then the length of the hypotenuse is 6√2 units.

Due to the fact that the triangle's legs are always the same length, d = 8. Always on the other side of the right angle is the hypotenuse. The hypotenuse of this triangle, represented by the letter e, is at its base. You must multiply the leg of a 45-45-90 triangle by the square root of two to determine the hypotenuse.

The hypotenuse of a 45°, 45°, and 90° triangle measures about two times the length of a leg.

In the right triangle ABC, AB is equal to AC

AB = AC = 6 units

BC is the hypotenuse

Applying the Pythagorean Theorem

BC² = AB² + AC²

substitute the values in the above equation, we get

BC² = 6² + 6²

Simplifying the above equation, we get

BC² = 72

BC = √72

BC = 6 √2 units

Therefore, the length of the hypotenuse is 6√2 units.

Answer:

what is the question I don't see it

Answer:

The equation of a line in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.

Given a point and the slope, we can find the equation of the line that passes through that point. We know that the slope of the line is 0, so we can write the equation of the line as:

y = 0x + b

We also know that the line passes through the point (-3,-8), so we can substitute these values into the equation and solve for b, the y-intercept:

-8 = 0(-3) + b

-8 = 0 + b

b = -8

So the equation of the line that passes through the point (-3,-8) and has a slope of 0 is:

y = 0x - 8

This line is a horizontal line with y-intercept -8, which means that the line passes through the point (0,-8)

Answer:

First we need to figure out what g equals

Since 6 x 8 = 48 your answer would be 8

6 x 8 = 48

~ LadyBrain

The value of g that satisfies the equation is 8.

To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:

6g / 6 = 48 / 6

This simplifies to:

g = 8

Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

The balance in the fund at the end of 23 years, with monthly deposits of $1,150 and a 3.25% annual interest rate, is approximately $449,069.51. The amount of interest earned over the period is approximately $420,630.49.

a. The balance in the fund at the end of the 23-year period, considering a monthly deposit of $1,150 and an annual interest rate of 3.25% compounded annually, is approximately $449,069.51.

To calculate the balance, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where A is the accumulated balance, P is the monthly deposit, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.

In this case, we have monthly deposits, so we need to convert the annual interest rate to a monthly rate:

Monthly interest rate = (1 + 0.0325)^(1/12) - 1 = 0.002683

Using this monthly interest rate, we can calculate the accumulated balance over the 23-year period:

A = 1150 * [(1 + 0.002683)^(12*23) - 1] / 0.002683 = $449,069.51

Therefore, the balance in the fund at the end of the 23-year period is approximately $449,069.51.

b. The amount of interest earned over the 23-year period can be calculated by subtracting the total deposits from the accumulated balance:

Interest earned = (Monthly deposit * Number of months * Number of years) - Accumulated balance

Interest earned = (1150 * 12 * 23) - 449069.51 = $420,630.49

Therefore, the amount of interest earned over the 23-year period is approximately $420,630.49.

True, you can use universal generalization (UG) to obtain a universal statement by generalizing only from a free variable, and not from a constant. Generalization involves making a statement that applies to all instances of the variable, while constants remain fixed and do not change in value.

True. Universal generalization (UG) allows us to derive a universal statement by generalizing from a free variable. General sampling deals with the fact that if something is true for everything, it must also be true for every specific thing called the constant c. Existential generalization deals with the fact that the special case c is true for at least one thing if it is true.

A free variable is a variable that is not bound by a quantifier, meaning it is not restricted to a specific value or range of values. In contrast, a constant is a variable that is already assigned a specific value and cannot be generalized over. Therefore, UG can only be applied to free variables and not constants.

the first thing you have to do is define a variable for stuff that you don't know. In this problem, you don't know any of the integers, so you should assign a variable to them.

will put  the first integer as n. The second integer, since it is right after the first, will be n+1. The third integer, since it is right after the second, will be (n+1)+1=n+2. consider the integers 1, 2, and 3. 2 is one more than 1, or in other words, 2=1+1. same for 3, except 3 is two more than 1, so 3=1+2. Since the integers are consecutive, each is one more than the last.We're told that the sum of our three integers is 15. Therefore, n+(n+1)+(n+2)=15 Solving this equation is pretty straightforward:

3n+3=15

3n=12

n=4 That means our first integer is 4. Our second integer is 4+1, or 5, and our third integer is 5+1, or 6. Our answer is confirmed because 4+5+6=15

If you take the test and get a positive result, the probability that you have tetrachromacy is approximately 0.3571 or 35.71%.

To determine the probability that you have tetrachromacy given a positive test result, we can use Bayes' theorem. Let's define the following probabilities:

P(T) = Probability of having tetrachromacy (10% or 0.1)

P(¬T) = Probability of not having tetrachromacy (90% or 0.9)

P(Pos|T) = Probability of a positive test result given tetrachromacy (true positive rate, 70% or 0.7)

P(Pos|¬T) = Probability of a positive test result given no tetrachromacy (false positive rate, 14% or 0.14)

We want to find P(T|Pos), the probability of having tetrachromacy given a positive test result.

According to Bayes' theorem:

P(T|Pos) = (P(Pos|T) * P(T)) / P(Pos)

To find P(Pos), the probability of a positive test result, we can use the law of total probability:

P(Pos) = P(Pos|T) * P(T) + P(Pos|¬T) * P(¬T)

Plugging in the values:

P(Pos) = (0.7 * 0.1) + (0.14 * 0.9)

= 0.07 + 0.126

= 0.196

Now we can calculate P(T|Pos):

P(T|Pos) = (P(Pos|T) * P(T)) / P(Pos)

= (0.7 * 0.1) / 0.196

= 0.07 / 0.196

≈ 0.3571

Therefore, if you take the test and get a positive result, the probability that you have tetrachromacy is approximately 0.3571 or 35.71%.

\(\implies 3(6x) \geq 14(5)\)

\(\implies 18x \geq 70\)

Divide both sides by 18:

\(\implies \dfrac{18x}{18} \geq \dfrac{70}{18}\)

\(\implies x \geq \dfrac{70}{18}\)

Reduce the fraction by dividing the numerator and the denominator by 2:
