Answer:

<u><em>64%</em></u>

Step-by-step explanation:

<em>1. Nine prime numbers between 1 and 25.</em>

<em>2. 25-9 = 16</em>

<em>3. Sixteen non-prime numbers between 1 and 25.</em>

<em>4. 16/25 = 0.64 = 64%</em>

Hope this helps!

Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval.ex = 8 − 7x, (0,
AnnZ [28]

Answer:

There is not root of the function 8-7x on the interval [0, 1].

Step-by-step explanation:

The Intermediate Value Theorem says:

<em>If f(x) is a continuous function on [a, b], then for every d between f(a) and f(b), there exists a value c in between a and b such that f(c) = d.</em>

This means that whenever we can show that:

  • there is a point above some line
  • and a point below that line, and
  • that the curve is continuous,

we can then safely say yes, there is a value somewhere in between that is on the line.

To show that there is solution 8-7x=0 between x = 0 and x = 1.

We evaluate the function at x = 0 and x = 1

f(0)=8-7(0)=8\\f(1)=8-7(1)=1

We know that

at x = 0, the line is above zero and

at x = 1 the line is above zero.

We also know that the function is continuous but because the line is always above zero there is no solution at the interval (0, 1).

We can check our work with the graph of the function.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

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.

Which description best compares the graph of y-3=-2(×+4)andy=-2×_5
rjkz [21]
Rewrite the first function so that the two functions are in standard form:

y - 3 = -2x - 8  => y = 3 - 2x - 8  =>  y = -2x - 5

and

y= -2x - 5

We can now see immediately that these two functions have the same slope (-2) and same y-intercept (providing that you meant "y = -2x - 5).

The graphs of these 2 functions are identical.
