Answer:

line ED

Step-by-step explanation:

Let analyse all possible answer:

a. line CD

From the photo, you can see it lies on the plane A and only point D is either on plane A or B.

b. line ED

From the photo, you can see the point E and D are lying on plane A and B.

c. point C

Only in plane A

d. point D

point D is on plane A or B.

However, to describes the intersection of 2 planes, we usually use the a line or a segment to have a better explanation because it goes through all the common points of the two planes

Find the mean and standard deviation for the set of data.

dem82 [27]

The mean and standard deviation for the set of data will be 16 and 5.87. Then the correct option is A.

<h3>What is a standard deviation?</h3>

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

The set of data is given below.

16, 22, 8, 5, 20, 18, 14, 17, 24

The mean of the data set will be

μ = (16 + 22 + 8 + 5 + 20 + 18 + 14 + 17 + 24) / 9

μ = 144 / 9

μ = 16

Then the standard deviation of the data set will be

$\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}} \\\sigma = \sqrt{\dfrac{(16 - 16)^2 +(22 - 16)^2 + (8-16)^2 + ......+(24-16)^2 }{9}} \\\sigma = \sqrt{\dfrac{310}{9}}\\$

Simplify the expression further, then we have

σ = √34.44

σ = 5.87

The mean and standard deviation for the set of data will be 16 and 5.87.

Then the correct option is A.

Consider the following functions.<br> f(x) = x^2- 4<br> g(x) = x-2<br> What is (f(x)) (g(x))?

rodikova [14]

Answer:

(f(x) g(x)) = $x^3-2x^2-4x+8 ;$ all real numbers

Step-by-step explanation:

(f(x) g(x)) = $(x^{2} -4)(x-2)$

= $x^3-2x^2-4x+8$ via FOIL

Write the linear equation in slope intercept form 2x+By=16

allochka39001 [22]

Answer:

Part 1) $y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2) $y=-\frac{1}{4}x+2$

Step-by-step explanation:

Part 1)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+By=16$

Isolate the variable y

subtract 2x both sides

$By=-2x+16$

Divide by B both sides

$y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+8y=16$

Isolate the variable y

subtract 2x both sides

$8y=-2x+16$

Divide by 8 both sides

$y=-\frac{2x}{8}x+\frac{16}{8}$

Simplify

$y=-\frac{1}{4}x+2$

Solve for ppp. 16-3p=\dfrac23p+516−3p= 3 2 p+516, minus, 3, p, equals, start fraction, 2, divided by, 3, end fraction, p, plus

Ksivusya [100]

Given:

The given equation is:

$16-3p=\dfrac{2}{3}p+5$

To find:

The value of p.

Solution:

We have,

$16-3p=\dfrac{2}{3}p+5$

Multiply both sides by 3.

$3(16-3p)=3\left(\dfrac{2}{3}p+5\right)$

$48-9p=2p+15$

Isolating the variable terms, we get

$48-15=2p+9p$

$33=11p$

Divide both sides by 11, we get

$\dfrac{33}{11}=p$

$3=p$

Therefore, the required solution is $p=3$ .

5a - 24b =-15<br> 10a + 45c =21<br> 48b + 35c = 49

andrew-mc [135]

5a + 15 = 24b so,

10a + 30 = 48b,

sub to third equation,

10a + 30 + 35c = 49

10a + 35c = 19

perform elimination with second equation

10a + 45c = 21

10a + 35c = 19

________________-

10c = 2

c = 1/5

sub to second equation,

10a + (45)(1/5) = 21

10a + 9 = 21

10a = 12

a = 6/5

sub to first equation

(5)(6/5) - 24b = -15

6 + 15 = 24b

21 = 24b

b = 7/8

redo the calculations, correct me if I'm wrong
