Can someone help me with this

Mathematics
1 answer:
Alexxandr [17]3 years ago
4 0

Answer:

Line 1: -2

Line 2: 2

Line 3: 2

Line 1 & 2 is parallel.

Line 2 & 3 is neither.

Step-by-step explanation:

To find the slope of a line use the slope formula and substitute the points into it:

Line 1

m = \frac{y_2-y_1}{x_2-x_1} =\frac{2--2}{0-2} =\frac{2+2}{-2} =\frac{4}{-2}=-2

Line 2

m = \frac{y_2-y_1}{x_2-x_1} =\frac{-5--1}{1--1} =\frac{-5+1}{1+1} =\frac{-4}{2}= -2

Line 3

m = \frac{y_2-y_1}{x_2-x_1} =\frac{0--4}{-3--5} =\frac{0+4}{-3+5} =\frac{4}{2}=2

Parallel lines have the same slope and perpendicular lines have negative reciprocal slopes.

Line 1 & 2 is parallel.

Line 2 & 3 is neither.

Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.
shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a)  The probability that exactly 21 of those surveyed feel the state of morals is poor is

P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519

(b)  The probability that no more than 22 of those surveyed feel that state of morals is poor is

=P(X

(c)  The probability that more than22 of those surveyed feel the state of morals is poor is

P(X>22)\\=1-0.9811\\=0.0119

(d)  The probability that 15 or 16 believe the state of morals is poor is

=P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507

Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inche
Vladimir [108]
Assuming that the sides of the box are square (having 90° angles on all four corners), then it should be relatively easy for us to find the length of the box, given the perimeter and the length of one side.
We know the length of all sides combined is 42 inches, and that the length of one side is 9 inches. With a rectangular prism, the length of one side is the same as the length of the opposite side, so there are two sides that measure 9 inches.
All we need to do to find the measure of both the other sides' lengths is subtract the known lengths from the total length.

9 + 9 = 18

42 - 18 = 24

So the rest of the side lengths added together is 24 inches.
There are two sides left, so all we have to do is divide by 2 to find the length of the box.

24 / 2 = 12

The length of Kate's jewelry box is 12 inches.
Hope that helped =)
