Answer:

  • Statistics;
  • Parameter;
  • Statistics;
  • Parameter.

Step-by-step explanation:

According to southeastern.edu,

  • parameters summarize data from an entire population, whereas
  • statistics summarize data from a sample of the population.

The first statement is true for the sample "those surveyed" the population but not necessarily the entire population. Statistic.

The second statement implies that the soccer team is the population. All members of the population are surveyed. Parameter.

The third statement states that a sample of 100 of all swimming teams are surveyed. Statistic.

The fourth statement implies that the population is all members of the golf team, and that all members of the population are surveyed. Parameter.

What is the new volume of a right square pyramid with a volume 180in.3 if the lengths of the sides of the base remain fixed but
garik1379 [7]
The volume of <span>a right square pyramid is V= \frac{1}{3} A_{\text{ basis } }\cdot h, where </span><span>A_{\text{ basis } } is basis area.
</span>
If the lengths of the sides of the base remain fixed and height
<span>is multiplied by a factor 10, than new height is H=10h and the volume is
</span>
V^{\ast}=A_{\text{ basis } }\cdot H=\frac{1}{3} A_{\text{ basis } }\cdot 10h=\frac{10}{3} A_{\text{ basis } }\cdot h

Find the 9th term of the geometric sequence 6,-24,96... <br><br>​
spin [16.1K]

Answer:

A9 = 393216

Step-by-step explanation:

the first thing that will help you solve this question is finding the common ratio between each terms

the first thing that I like to do that usually helps is to take the second term (-24) and divide it by the first term (6) --> this will usually help you spot the common ratio fairly quickly

in your case, the common ratio is -4

- you can also check this by following my note above and then multiplying the second term by the common ratio to see if it matches the third term, which it does!

so now you can go about this two different ways

1. solve directly for the 9th term

2. use the nth term formula for geometric sequences

METHOD 1:

if you continue to multiply by -4 to solve for each term you would end up with:

6, -24, 96, -384, 1536, -6144, 24576, -98304, 393216

and you will recieve 393216 as your answer

METHOD 2:

the nth term formula is An = A1*r^(n-1)

where An = the nth term of the sequence

A1 = first term of the sequence (6)

and r = common ratio

using this formula, you would get:

A9 = 6(-4)^8

A9 = 393216

I hope this helped :)

B-4/6 how do I solve this? It's hard
serious [3.7K]
                                     
if you are looking for.... 2(B-4)= (6)b
                                     2b - 8 = 6b
                                     2b - 6b= 8
                                     -4b=8
                                      so b= -2

the question is b-4 divided by 6 equals b/2
