Please help quick.

GREYUIT [131]

Answer:

The answer to your question is: third option is correct

Step-by-step explanation:

Data

F (5, -1)

directrix y = 1

Then, after getting the graph, the vertix = (5, 0)

and p = 1

Formula

(x - h) ² = -4p(y - k)

(x - 5)² = -4(1)(y - 0)

(x - 5)² = -4y

y = (x - 5)² / -4

What conclusions can be drawn about finding the quotient in scientific notation? Check all that apply. Start Fraction (9.6 times

Nadusha1986 [10]

The quotient of the expressions (9.6 x 10⁻⁸) and (3.2 x 10⁴) is 3.0 × 10⁻¹². Then the correct option is D.

<h3>What is division?</h3>

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The expressions are given below.

(9.6 x 10⁻⁸) and (3.2 x 10⁴)

Then the quotient of the expressions will be

⇒ (9.6 x 10⁻⁸) / (3.2 x 10⁴)

⇒ (3 x 10⁻⁸) / (10⁴)

⇒ 3 x 10⁻⁸ x 10⁻⁴

⇒ 3 x 10⁻⁸⁻⁴

⇒ 3 x 10⁻¹²

Then the correct option is D.

Robbie, has scored 120 so far this season. He has scored all of his points on 1-point extra point kicks and 3-point field goals.

joja [24]

Answer:

39 and 27

Step-by-step explanation:

GIVEN: Robbie, has scored $120$ so far this season. He has scored all of his points on $1$ -point extra point kicks and $3$ -point field goals. He has made a total of $66$ kicks.

TO FIND: How many of each kick has he made.

SOLUTION:

Lets extra point kicks made by Robbie be $x$

points scored using extra point kick $=1$

field goal kicks made by Robbie $=66-x$

point scored using field goal kick $=3$

Total points scored by Robbie $=120$

Total points scored are the sum of points scored by extra point kicks and field goal kicks.

$1\times x+(66-x)3=120$

$198-2x=120$

$2x=78$

$x=39$

total extra point kicks $=39$

total field goal kicks $=66-39=27$

Hence Robbie made 39 and 27 kicks of extra point kick and field goal kicks respectively.

1) Find the 95 % confidence interval for the mean if σ = 11 , using this sample:

melamori03 [73]

Answer:

The 95 % confidence interval for the mean is between 28.09 and 35.97.

Step-by-step explanation:

Mean of the sample:

30 values.

So we sum all the values and divide by 30.

The sum of all the values(43 + 52 + 18 + ... + 20 + 41) is 961.

961/30 = 32.03

Confidence interval:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96\frac{11}{30} = 3.94$

The lower end of the interval is the sample mean subtracted by M. So it is 32.03 - 3.94 = 28.09

The upper end of the interval is the sample mean added to M. So it is 32.03 + 3.94 = 35.97

The 95 % confidence interval for the mean is between 28.09 and 35.97.
