A wheelchair ramp rises 2.25 feet for every 25feet of horizontal distance it covers what is the slope of the ramp

4 x (5+5) I need the distributive property and the answer please I need it ASAP!

Paraphin [41]

4 x 5 x 5 is 100 if u distribute

Now 5 + 5 x 4 is 25

Alexxandr [17]

Answer:

a ) dAt/dt = 50,24 in/min

dh/dt = - 0,125 in/min

Step-by-step explanation:

The area of the top is At :

At = π*r²

a) Tacking derivatives with respect to time:

dAt/dt = 2* π*r * dr/dt

At t = t₁ r = 16 in and dr/dt = 0,5

Then

dAt/dt = 2*3,14*16*0,5 in/min

a ) dAt/dt = 50,24 in/min

b) The volume of the cylinder is:

Vc = π*r²*h ( where h is the heigh of the cylinder )

Tacking derivatives with respect to time

dVc/dt = 2* π*r*h*dr/dt + π*r²*dh/dt

But dVc/dt = 0 since the volume remains constant, then:

π*r²*dh/dt = - 2* π*r*h*dr/dt

r*dh/dt = - 2*h*dr/dt

dh/dt = - 2*0,5*2/16 in/min

dh/dt = - 0,125 in/min

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who

Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

Explanation:-

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-

when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be small, large but finite or infinite.

Example :- 1

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are finite number of observations.

Example :- 2

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

Population:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the population

The number of observations in the population is defined to be the size of the population.

Example :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

Sample:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population
