7/9 z - 18 + 1/3z if z = 27

Answers

Answer 1

Answer:

12

Step-by-step explanation:

7/9 x 27 - 18 + 1/3 x 27

Express 7/9 ×27 as a single fraction.

7 x 27 / 9 - 18 + 1/3 x 27

Multiply 7 and 27 to get 189.

189/9 - 18 + 1/3 x 27

Divide 189 by 9 to get 21.

21 - 18 + 1/3 x 27

Subtract 18 from 21 to get 3.

3 + 1/3 x 27

Multiply 1/3 and 27 to get 27/3.

3 + 27/3

Divide 27 by 3 to get 9.

3+9

Add 3 and 9 to get 12.

Assume a test for a disease has a probability 0.05 of incorrectly identifying an individual as infected (False Positive), and a probability 0.01 of incorrectly identifying an individual as uninfected (False Negative). Assume furthermore that the probability of an individual being infected is 0.000001 (1 in 1 million). If a person tests positive for this disease, what is the probability of actually having the disease

Answers

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

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

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

[tex]P(A \cap B)[/tex] 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

[tex]P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094[/tex]

Probability of a positive test and having the disease:

0.99 of 0.000001. So

[tex]P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}[/tex]

What is the probability of actually having the disease

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

0.00002 = 0.002% probability of actually having the disease

Ben Frank is an electrician who installs lighting fixtures. He charges (in dollars) his clients 15h +40f
where h is the number of hours worked and f is the number of fixtures installed.
How much does Ben Frank charge when he works 7 hours and installs 9 fixtures?

Answers

Answer:

465 Dollars

Step-by-step explanation:

15h+40f = Amount Charged

if: h = 7

   f = 9

15(7)+40(9) = Amount Charged

105 + 360 = Amount Charged

465 = Amount Charged

He will charge 465 dollars.

Answer:$465Steps and explanation of why:

Ben works 7 hours installing 9 fixtures. This tells us that h = 7, and f = 9. So, let's substitute h = 7 and f = 9 into the expression and evaluate:

Step 1:

15h + 40f

Step 2:

= 15(7) + 40(9)

Step 3:

= 105 + 360

Step 4:

= $465

When plotting points on the coordinate plane below, which point would lie on the x-axis?



(6, 0)
(0, 2)
(3, 8)
(5, 5)

Answers

Answer: (6,0)

Coordinate points are always written in pairs of the x- and y-coordinate: (x, y). Knowing this, the point would need to have a y-value of 0 in order to lie on the x-axis (otherwise, it would be on a random spot on the grid). The only coordinate point with a y-value of 0 is (6, 0). Therefore, the coordinate point (6, 0) lies on the x-axis.

Please refer to the attached graph below to see all the coordinate points.

Answer

•Pic on the left

x = 8.36

y = 140.18°

• Pic on the right

x = 110°

Way to do

This one for the pic on the left

#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)

#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D

90 = (5x - 2) + 6x

90 = 11x - 2

90 + 2 = 11x

92 = 11x

x = 92 : 11

x = 8.36 (2 decimal places)

#Now you know the x, you can now find the degree

#degree of (5x - 2)

5x - 2 =

5(8.36) - 2 =

41.81 - 2 = 39.81

#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)

180° - 39.81° = 140.18

This one for the pic on the right

#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.

# Also as i said before, total triangle degree is 360°

#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)

Degree = 180° - 80° - 30° = 70°

#Now you can get x

x = 180° - 70° = 110°

Answer:

[tex] \sqrt{32} + 3[/tex]

[tex] - \sqrt{32} + 3[/tex]

Step-by-step explanation:

Use foil method

[tex](y - 3) {}^{2} [/tex]

[tex](y - 3)( y - 3)[/tex]

First multiply y and y

[tex]y \times y = {y}^{2} [/tex]

Next Multiply Outer term y and -3.

[tex]y \times - 3 = - 3y[/tex]

After that ), Multily inner tern -3 and y

[tex] - 3 \times y = - 3y[/tex]

Finally multiply -3 and -3 and you get 9.

Then combine all

[tex] {y}^{2} - 6y + 9 - 32 [/tex]

[tex] {y}^{2} - 6y - 23[/tex]

Now I'm going to complete the square. First get only the y value on the left side so we first set this equal to zero then move add 23 on both sides.

[tex] {y}^{2} - 6y - 23 = 0[/tex]

Add 23

[tex]y {}^{2} - 6y = 23[/tex]

Apply formula

[tex] (\frac{b}{2} ) {}^{2} [/tex]

where b is the coefficient.

plug it in

[tex]( \frac{ - 6}{2}) {}^{2} [/tex]

Which is -3 squared which equal 9.

Then add 9 on both sides

[tex] {y}^{2} - 6y + 9 = 23 + 9[/tex]

23+9=32

Now let factor the left side

the only number that adds to -6 and multiply to 9 is

-3 so we would rewrite the left side as

[tex](x - 3) {}^{2} = 32[/tex]

Now take the sqr root of 32

[tex] \sqrt{(x - 3) {}^{2} } = \sqrt{32} [/tex]

Then add 3 on both sides

[tex]x + - 3 + 3 = \sqrt{32} + 3[/tex]

A sqr root of a number can be positive or negative so

the answer is

[tex] - \sqrt{32} + 3[/tex]
