Mathematics
1 answer:
Dovator [93]3 years ago
7 0

Answer:

-x²+8x-15

Step-by-step explanation:

There are two solutions: 3 and 5

First, let's write the equation in this form (pay attention, the parabola here is going up so it won't be like your graph):

(x-3)(x-5)

For resolve our problem, let's re-write it with a minus before:

-(x-3)(x-5)

You can also expand it and the result will be like this:

-x²+8x-15

Represent the geometric series using the explicit formula.
user100 [1]

Answer:  f(n)=12(-3)^{(n-1)}

Step-by-step explanation:

The Explicit formula in function notation for a geometric series is:

f(n)=f(1)r^{(n-1)}

Where f(n) is the nth term of the sequence, f(1) is the first term in the sequence and r is the common ratio.

Given the following geometric serie:

12, -36, 108, -324...

The common ratio is:

r=\frac{-36}{12}=-3

And the first term is:

f(1)=12

Therefore, substituting values, we get that the Explicit formula that represents this geometric series is:

f(n)=12(-3)^{(n-1)}

According to a random sample taken at 12​ A.M., body temperatures of healthy adults have a​ bell-shaped distribution with a mean
mrs_skeptik [129]

Answer:

There are 89% of healthy adults with body temperatures that are within 3 standard deviations of the​ mean

The minimum value that is within 3 standard deviations of the mean is 96.57.

The maximum value that is within 3 standard deviations of the mean is 100.11.

Step-by-step explanation:

Chebyshev's theorem states that a minimum of 89% of the values lie within 3 standard deviation of the mean.

So

Using​ Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 3 standard deviations of the​ mean?

There are 89% of healthy adults with body temperatures that are within 3 standard deviations of the​ mean.

What are the minimum and maximum possible body temperatures that are within 3 standard deviations of the​ mean?

We have that the mean \mu is 98.34 and the standard deviation \sigma is 0.59. So:

Minimum

Mi = \mu - 3\sigma = 98.34 - 3(0.59) = 96.57

Maximum

Ma = \mu + 3\sigma = 98.34 + 3(0.59) = 100.11
