The equation of line passing through (6,-5) and parallel to line with slope 4/3 is:

y=\frac{4}{3}x-13

Further explanation:

Given

Slope of line= 4/3

Point = (6,-5)

As the given line is parallel to the line whose slope is given. This means that the slope of the required line will be same as parallel lines have equal slope.

The general form of point-slope form is:

y=mx+b

Putting the value of slope

y=\frac{4}{3}x+b

To find the value of b, putting (6,-5) in equation

-5=\frac{4}{3}(6)+b\\-5 = (4)(2)+b\\-5=8+b\\b=-5-8\\b=-13

Putting the values of b and m

y=\frac{4}{3}x-13

The equation of line passing through (6,-5) and parallel to line with slope 4/3 is:

y=\frac{4}{3}x-13

a water tank can hold up 80 gallons of water. if it is 40% full now. how many gallons of water does the tank contain?
valkas [14]

Answer:

32 gallons of water

Step-by-step explanation:

If the total tank can hold up to 80 gallons of water, it is considered full when it contains 80 gallons. When the tank is 40% full, it has 40% of 80 gallons in the tank. 40% of 80 is 40/100*80=8*4=32 gallons of water.

5x^(-2)-17x^(-1)+6<br> i’m so confused pls help<br> will give brainliest
laila [671]

It's a quadratic equation in disguise. If you let y=x^{-1}, then y^2=x^{-2}, and we can rewrite the equation as

5y^2-17y+6=0

Solve for y however you like; we get y=\dfrac25 and y=3.

But we want to solve for x, so we have

y=x^{-1}=\dfrac25\implies x=\dfrac52

y=x^{-1}=3\implies x=\dfrac13

Consider the probabilities of people taking pregnancy tests. Assume that the true probability of pregnancy for all people who ta
Valentin [98]

Using conditional probability, it is found that there is a 0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula 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 problem, the events are:

  • Event A: Positive test result.
  • Event B: Pregnant.

The probability of a positive test result is composed by:

  • 99% of 10%(truly pregnant).
  • 2% of 90%(not pregnant).

Hence:

P(A) = 0.99(0.1) + 0.02(0.9) = 0.117

The probability of both a positive test result and pregnancy is:

P(A \cap B) = 0.99(0.1)

Hence, the conditional probability is:

P(B|A) = \frac{0.99(0.1)}{0.117} = 0.8462

0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.
