The equation of the line with a slope of 6 and y-intercept of -1 is:

Andrew [12]

Answer:

$\bold{y=6x-1}$

Step-by-step explanation:

Hi there!

Since we are given the slope and the y-intercept of the line, we can very easily identify the equation of the line.

Slope-intercept:

y=mx+b

Plug in the values:

$\bold{y=6x-1}$

Thus, $\bold{y=6x-1}$ is the equation of the line.

Hope it helps! Enjoy your day!

Assume a test for a disease has a probability 0.05 of incorrectly identifying an individual as infected (False Positive), and a

Nana76 [90]

Answer:

0.00002 = 0.002% probability of actually having the disease

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: Positive test

Event B: Having the disease

Probability of having a positive test:

0.05 of 1 - 0.000001(false positive)

0.99 of 0.000001 positive. So

$P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094$

Probability of a positive test and having the disease:

0.99 of 0.000001. So

$P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}$

What is the probability of actually having the disease

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{9.9 \times 10^{-7}}{0.05000094} = 0.00002$

0.00002 = 0.002% probability of actually having the disease

Charlie measured the circle-shaped part of a sun his sister drew on the chalkboard. The circumference of the circle is 75.36 cm.

ch4aika [34]

Answer:

The diameter of circle is 24 cm.

Step-by-step explanation:

We are given the following in the question:

Circumference of circle = 75.36 cm

We have to find the diameter of the circle.

Circumference of circle =

$C =2\pi r$

where r is the radius of the circle.

Putting values, we get,

$75.36 = 2\times 3.14\times r\\\\r = \dfrac{75.36}{2\times 3.14}\\\\r=12$

Diameter of circle =

$d=2r\\d=2\times 12=24\text{ cm}$

Thus, the diameter of circle is 24 cm.
