Use the standard normal distribution to find P(-2.25 < z < 1.25)
Ede4ka [16]

Here we have to find the probability P(-2.25. Now express the probability in terms of standard normal cumulative distribution function. That is \Phi(x)=P(z.

P(-2.25

Now you can look up the probability from the standard normal tables. Its value is

P(-2.25

Answer:

No real roots

Step-by-step explanation:

Given

7x² + 5x + 1 = 0 ← in standard form

with a = 7, b = 5, c = 1

To determine the nature of the roots use the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then the roots are not real

Here

b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3

Thus the 2 roots are not real

You will be brainliest please list correct answer and the mistake he made
anzhelika [568]

<em>Hey There!!</em>

<em>The answer is below!!</em>

Step-by-step explanation:

We move all terms to the left:

-6n+22-(-4n+14-10n+22)=0

We add all the numbers together, and all the variables

-6n-(-14n+36)+22=0

We get rid of parentheses

-6n+14n-36+22=0

After that, We add all the numbers together, and all the variables

8n-14=0

Then, We move all terms containing n to the left, all other terms to the right

8n=14

n=14/8

n=1+3/4

<em>I don't know this is </em>100% right....

So.....GoodLuck!!
