Marysya12 [62]

Answer:

Step-by-step explanation:

1.

a)

Find the vertex by completing the square to answer both a and b

d)

x-ints is when y=0

so use quadratic equation for

b^2-20b+200=0

a=1

b= -20

c=200

But notice these imaginary numbers means 0 x intercepts.

A simple random sample of 125 SAT scores has a mean of 1522. Assume that SAT scores have a population standard deviation of 335.
Fed [463]

Answer:

1463.3\:

Step-by-step explanation:

Since the population standard deviation \sigma, is known, we use the z confidence interval for the mean.

This is given by:

\bar X-z_{\frac{\alpha}{2} }(\frac{\sigma}{\sqrt{n} } )\:

For a 95% confidence interval we use z=1.96.

It was also given that: n=125, \bar X=1522 and \sigma=335

Let us substitute the values to get:

1522-1.96(\frac{335}{\sqrt{125} } )\:

1463.3\:

<u>Interpretation:</u>

We can say with 95% confidence that the interval between 1463.3 and 1580.7 SAT scores contains the population mean based on the sample 125 SAT scores.

What is the right-hand limit of the function `f(x) = (x^2 + 2x - 3)/(x - 3)` as x approaches 2?

Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many
GREYUIT [131]

200 flying insects she catch for her project .

<u>Step-by-step explanation:</u>

We have , Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many insects that could fly as insects that couldn't fly. That means insects ratio of non-fly to fly is 1:8 .

There are a total of 225 insects , and for every one non fly insect there are 8 fly insects  , Let x be the number of insects that can't fly so:

x + 8x = 225

⇒ x + 8x = 225

⇒ 9x = 225

⇒ \frac{9}{9}x = \frac{225}{9}

⇒ x = \frac{225}{9}

⇒ x = 25

So , Number of fly insects = 8x = 8(25) = 200 . ∴ 200 flying insects she catch for her project .
