It would be C. since the -7 means you move 7 units downwards on the graph, and E. since smaller slopes are wider, whereas larger slopes are more narrow

Answer:

0.5015 = 50.15% probability that it came from manufacturer A.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Defective

Event B: From manufacturer A.

Probability a unit is defective:

2% of 43%(from manufacturer A)

1.5% of 57%(from manufacturer B). So

$P(A) = 0.02*0.43 + 0.015*0.57 = 0.01715$

Probability a unit is defective and from manufacturer A:

2% of 43%. So

$P(A \cap B) = 0.02*0.43 = 0.0086$

What is the probability that it came from manufacturer A?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0086}{0.01715} = 0.5015$

0.5015 = 50.15% probability that it came from manufacturer A.

Answer:

The remaining lenghts are $x = 20.364\,cm$ and $y = 12.925\,cm$ .

Step-by-step explanation:

Given that there are two triangles opposite to each other and between two parallel lines, then both are similar, meaning than following relationships exist:

$\frac{AC}{CD} = \frac{BC}{CE} = \frac{AB}{DE}$ (1)

If we know that $AC = 11\,cm$ , $CD = 28\,cm$ , $BC = 8\,cm$ and $DE = 32.9\,cm$ , then the missing lengths are, respectively:

$\frac{11\,cm}{28\,cm} = \frac{8\,cm}{x}$

$x = \frac{(28\,cm)\cdot (8\,cm)}{11\,cm}$

$x = 20.364\,cm$

$\frac{11\,cm}{28\,cm} = \frac{y}{32.9\,cm}$

$y = \frac{(11\,cm)\cdot (32.9\,cm)}{28\,cm}$

$y = 12.925\,cm$

The remaining lenghts are $x = 20.364\,cm$ and $y = 12.925\,cm$ .

For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.
Hope this helps Xx
