Answer:

B (-2 , -11)

Step-by-step explanation:

hello : the system is :

y = 4x - 3

y= -x - 13

put x = -2

y = 4(-2) - 3=- 11

y= -(-2) - 13 = -11

Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 100 sam

Vlad [161]

Answer

$P(A) = 0.30$

$P(B) = 0.77$

$P(A\ n\ B) = 0.22$

$P(A\ u\ B) = 0.85$

Explanation:

Given

See attachment for proper data presentation

$n = 100$ --- Sample

A = Supplier 1

B = Conforms to specification

Solving (a): P(A)

Here, we only consider data in sample 1 row.

Here:

$Yes = 22$ and $No = 8$

$n(A) = Yes + No$

$n(A) = 22 + 8$

$n(A) = 30$

P(A) is then calculated as:

$P(A) = \frac{n(A)}{Sample}$

$P(A) = \frac{30}{100}$

$P(A) = 0.30$

Solving (b): P(B)

We only consider data in the Yes column.

Here:

$(1) = 22$ $(2) = 25$ and $(3) = 30$

$n(B) = (1) + (2) + (3)$

$n(B) = 22 + 25 + 30$

$n(B) = 77$

P(B) is then calculated as:

$P(B) = \frac{n(B)}{Sample}$

$P(B) = \frac{77}{100}$

$P(B) = 0.77$

Solving (c): P(A n B)

Here, we only consider the similar cell in the yes column and sample 1 row.

i.e. [Supplier 1][Yes]

This is represented as: n(A n B)

$n(A\ n\ B) = 22$

The probability is then calculated as:

$P(A\ n\ B) = \frac{n(A\ n\ B)}{Sample}$

$P(A\ n\ B) = \frac{22}{100}$

$P(A\ n\ B) = 0.22$

Solving (d): P(A u B)

This is calculated as:

$P(A\ u\ B) = P(A) + P(B) - P(A\ n\ B)$

This gives:

$P(A\ u\ B) = \frac{30}{100} + \frac{77}{100} - \frac{22}{100}$

Take LCM

$P(A\ u\ B) = \frac{30+77-22}{100}$

$P(A\ u\ B) = \frac{85}{100}$

$P(A\ u\ B) = 0.85$

The y-intercept of the line which contains the following points (-8-35) and (6,21)

AlladinOne [14]

Answer:

The answer to your question is -3

Step-by-step explanation:

Data

A (-8, -35)

B (6, 21)

Process

1.- Calculate the slope

slope = m = (y2 - y1) / (x2 - x1)

x1 = -8 y1 = -35 x2 = 6 y2 = 21

-Substitution

m = (21 + 35) / (6 + 8)

-Simplification

m = 56 / 14

-Result

m = 4

2.- Calculate the equation of the line

y - y1 = m(x - x1)

-Substitution

y + 35 = 4(x + 8)

-Simplification

y + 35 = 4x + 32

y = 4x + 32 - 35

-Result

y = 4x - 3

3.- Find the y-intercept

The y-intercept is the number after the x, for this equation is -3.
