Answer:

1)<u>Nomina</u>l:-the name of their cell phone provider (AT&T, Verizon, and so on),

2)<u>Ratio</u>:- the numbers of minutes used last month (200, 400, for example),

3) <u>Ordinal</u>:- (Terrible, Adequate, Excellent, and so forth).

Step-by-step explanation:

The nominal level of measurement classifies data into mutually exclusive categories in which no order or ranking is imposed on the data set.

An example gathering information on college undergraduates base on the name of their cell phone provider (AT&T, Verizon, and so on).

The ratio level measures variables like time,weight, height, etc.

An example is the numbers of minutes used last month making phone calls by the college students. (200, 400, for example)

The ordinal level classifies data into categories that can be ranked (ordered)

Example ranking the satisfaction derived from the use of the service providers as  (Terrible, Adequate, Excellent, and so forth).

x = 27/4,5

x = 6 $ per kilogram

Fresh pond has a population of 854 and is increasing by 3 people per year. Strawberry has a population of 427 and is increasing
lawyer [7]

Answer:

  • Fresh Pond: p(t) = 854 +3t
  • Strawberry: p(t) = 427·1.10^t

Step-by-step explanation:

(a) The general term of an arithmetic sequence is ...

  an = a1 + d(n -1)

If we let the sequence of population numbers be modeled by this, and we use t for the number of years, we want n=1 for t=0, so n = t+1 and we have ...

  p(t) = 854 +3(t+1-1)

  p(t) = 854 +3t

__

(b) The general term of a geometric sequence is ...

  an = a1·r^(n-1)

were r is the common ratio. Here, the multiplier from one year to the next is 1+10% = 1.10. Again, n=t+1, so the population equation is ...

  p(t) = 427·1.10^(t+1-1)

  p(t) = 427·1.10^t

Mike is preparing refreshments for a party. To make a smoothie, he will mix 3 1⁄2 quarts of strawberry puree with 2 pints of lem
Shkiper50 [21]
Let's convert all volumes into pint:

1 Quart  = 2 pints → 3.5 quart of strawberry = 2 x 3.5 = 7 pints Strawberry
1 Gallon = 8 pints →1.25 Ga. water = 1.25 x 8 = 10 pints Water
2 pints of limonade = 2 pints of limonade 

Add up all pints Total = 7+10+2 = 19 pints of smoothie

Or in quart 9.5

Or in Gal 2.375

Jesse and Mark are jogging along the route shown at a rate of 12 miles per hour. They start by jogging south along Capitol Stree
Ilya [14]
The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours. Further, for Mark to be back to the starting point, the total distance covered is 2.75. Dividing the distance by 12 miles per hour, it will take Mark only 0.23 hours. Thus, Mark will reach the initial point first.
