The maximum score in the sample of cactus heights is 7 feet.

The scientist collected a sample of data on cactus heights. The minimum score in the sample was 3 feet and the range was 4 feet. The question asks for the maximum score in the sample. To find the maximum score, we can use the formula:

Maximum score = Minimum score + Range

Substituting the given values, we get:

Maximum score = 3 feet + 4 feet = 7 feet

Therefore, the maximum score in the sample of cactus heights is 7 feet.

To calculate the ratio of the tension (Tt) in the string when the ball is at the top of its path to (Tb) when the ball is at the bottom of its path, follow these steps:

1. At the top of the path, the tension Tt and gravitational force mg act in the same direction. The centripetal force is provided by the sum of these two forces. Therefore:
  Tt + mg = (m*v^2)/l

2. At the bottom of the path, the tension Tb acts opposite to the gravitational force mg. The centripetal force is provided by the difference between these two forces. Therefore:
  Tb - mg = (m*v^2)/l

3. Divide the equation at the top of the path by the equation at the bottom of the path to find the ratio Tt/Tb:
  (Tt + mg)/ (Tb - mg) = ((m*v^2)/l) / ((m*v^2)/l)

4. The centripetal force terms on the right side of the equation cancel out:
  (Tt + mg)/ (Tb - mg) = 1

5. Rearrange the equation to find the ratio Tt/Tb:
  Tt/Tb = (Tb - mg) / (Tt + mg)

So, the ratio of the tension Tt in the string when the ball is at the top of its path to Tb when the ball is at the bottom of its path is (Tb - mg) / (Tt + mg).What is Ratio: The relative size of two quantities expressed as the quotient of one divided by the other; the ratio of a to b is written as a:b or a/b.

The interest rate will be 7%

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount.

Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

The formula for simple interest is:

S = p*t*r/100

the simple interest on ​$7000 for 7 years is ​$3430

r = S*100/(p*t)

r = (3430*100)/(7000*7)

r = 7%

Hence the interest rate will be 7%

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

The formula for finding the volume of a pyramid with a square base is :

(1/3) * side length squared * height.

The formula for the volume of a pyramid with a square base is:

Volume = (1/3) * Base Area * Height

Where:

Base Area is the area of the square base of the pyramid (length of one side squared: A = s^2, where "s" is the length of one side of the square base)

Height is the perpendicular distance from the base to the apex (top) of the pyramid.

Combining these values, the formula becomes:

Volume = (1/3) * s^2 * Height

So, the volume of a pyramid with a square base can be calculated by multiplying one-third of the base area by the height of the pyramid.

True. Triangulation can be used to find the location of an object by measuring the angles.

Triangulation is a method used to determine the location of an object by measuring the angles between the object and two or more reference points whose locations are known.

This method is widely used in surveying, navigation, and various other fields.

By measuring the angles, the relative distances between the object and the reference points can be determined, and then the location of the object can be calculated using trigonometry.

Triangulation is commonly used in GPS systems, where the location of a GPS receiver can be determined by measuring the angles between the receiver and several GPS satellites whose locations are known.

According to the statement

we have to find that the what percent of the population has an iq over 115.

And from given information,

the mean iq score is 100 and the standard deviation is 15.

And

Normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

And by use of this formula, we find the percentage of the population has an iq over 115.

Then the result will comes as 100%.

hence, 100%-Norm.Dist(value,mean,sd,true)

The obtained answers for the given piecewise function are:

(a) The cost of a call that is under six minutes is 0.70 (m < 6)

(b) The cost of a 14-minute call is 2.62 (m > 6; m is an integer)

(c) The cost of a 9 1/2 minute call is 1.66 (m > 6; m is not an integer)

A piecewise function is given by different functions at different intervals.

It is given that,

phone company set the following rate schedule for an m-minute call from any of its pay phones.

C(m) = 0. 70 when m ≤ 6

        = 0.70 + 0.24(m - 6) when m > 6 and m is an integer

        = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer

(a) The cost of a call that is under six minutes:

Since m < 6, the cost is C(m) = 0.76

Thus, the cost of a call that is under six minutes is 0.76

(b) The cost of a 14-minute call:

Since 14 > 6, the cost is C(m) = 0.70 + 0.24(m - 6) when m > 6 and m is an integer.

C(14) = 0.70 + 0.24(14 - 6)

        = 0.70 + 0.24(8)

        = 0.70 + 1.92

        = 2.62

Thus, the cost of a 14-minute call is 2.62.

(c) The cost of a 9 1/2 minute call:

9 1/2 = 19/2 = 9.5

Since 9.5 > 6, the cost is C(m) = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer.

C(9.5) = 0.70 + 0.24([9.5 - 6] + 1)

          = 0.70 + 0.24([3.5] + 1)

Since we know that if [x] is a function then its domain is R and the range is Z(integer)

So, [3.5] = 3(is an integer)

Then,

C(9.5) = 0.70 + 0.24(3 + 1)

          = 0.70 + 0.96

          = 1.66

Therefore, the cost of a 9 1/2 minute call is 1.66.

The ratio of nickels to dimes in the spare change on the dresser is 9:8. This means that for every 9 nickels, there are 8 dimes in the spare change on the dresser.

Let's start by assigning variables to the number of pennies, nickels, and dimes. We can represent the number of pennies as 2x, where x is a positive integer. According to the given ratio of pennies to nickels (2:3), the number of nickels would be 3/2 times the number of pennies, which is 3x. Similarly, according to the ratio of pennies to dimes (3:4), the number of dimes would be 4/3 times the number of pennies, which is 8x/3.

To find the ratio of nickels to dimes, we need to compare their quantities. The number of nickels is 3x, and the number of dimes is 8x/3. To make the comparison easier, we can multiply both quantities by 3 to eliminate the fractions. This gives us 9x nickels and 8x dimes.

Therefore, the ratio of nickels to dimes is 9:8. This means that for every 9 nickels, there are 8 dimes in the spare change on the dresser.
