Answer:

  • 32 people

Step-by-step explanation:

Looking at the graph, we can say that 40% of the people rode the bus. We also know that 80 people took the survey.

<u>Solution:</u>

  • 40/100 x 80
  • => 2/5 x 80
  • => 2 x 16
  • => 32 people

Hence, 32 people rode the bus.

Calculate a_57 for the sequence {a_n}={-6,-9/2,-3,-3/2,0}
Archy [21]

Answer:the 57th term is 78

Step-by-step explanation:

The sequence is an arithmetic sequence. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = - 6

d =3/2

n = 57

We want to determine the value if the 57th term, T57. Therefore,

T57 = - 6 + (57 - 1) ×3/2

T57 = - 6 + 56 × 3/2 = - 6 + 84

T57 = 78

Mathematically derive a set of values for b and c such that the interval [0, 10] represents the solution to the inequality |x−b|
Roman55 [17]

Answer: Ix - 5I ≥ 5.

Step-by-step explanation:

We want the set:

[0, 10]

to be the solution of:

Ix - bI ≤ c

So we need to find the values of c and b.

The first step is to find the middle point in our segment.

We can do that by adding the extremes and dividing it by 2.

M = (10 + 0)/2 = 5

And we also want to find half of the difference between the extremes, this is:

D = (10 - 0)/2 = 5.

Now, this set will be the set of solutions of:

Ix - MI ≥ D

Then in our case, we have:

Ix - 5I ≥ 5.

so we have that b = 5, and c = 5.
