express the ratio below in its simplest form.3:12:9

Answer: See below

Step-by-step explanation:

Let A represent an adult who visited a therapist

Let B represent an adult who used a non-prescription antidepressant

Given:
P(A) = 0.28 P

P (B) = 0.43

P(A Intersection B) = 0.22

a) P(B ∩ A) = P (B ∩ A) / P(A) = 0.22/0.27

P(B | A) = 0.79 or 79%

b)  P(A ∩ B) = P (A ∩ B) / P(B) = 0.22/0.4.3

P(A | B) = 0.51 or 51%

Answer:

(a)  44.44%

(b)  71.43%

Step-by-step explanation:

Let A = adults who visited a therapist.

Let B = adults who used antidepressants.

Therefore:

[tex]\boxed{\begin{minipage}{5 cm}\underline{Conditional Probability formula}\\\\A given B:\\\\$\sf P(A|B)=\dfrac{P(A \cap B)}{P(B)}$\\\end{minipage}}[/tex]

To calculate the probability that an adult visited a therapist (Event A) during the past year, given that he or she used antidepressants (Event B), use the conditional probability formula for A given B:

[tex]\implies \sf P(A | B)=\dfrac{PA \cap B)}{P(B)}[/tex]

[tex]\implies \sf P(A | B)=\dfrac{0.2}{0.45}[/tex]

[tex]\implies \sf P(A | B)=0.444444...[/tex]

[tex]\implies \sf P(A | B)=44.44\%\;\; (nearest\; hundredth)[/tex]

[tex]\boxed{\begin{minipage}{5 cm}\underline{Conditional Probability formula}\\\\B given A:\\\\$\sf P(B|A)=\dfrac{P(A \cap B)}{P(A)}$\\\end{minipage}}[/tex]

To calculate the probability that an adult used antidepressants (Event B), given that he or she visited a therapist (Event A) during the past year, use the conditional probability formula for B given A:

[tex]\implies \sf P(B | A)=\dfrac{P(A \cap B)}{P(A)}[/tex]

[tex]\implies \sf P(B | A)=\dfrac{0.2}{0.28}[/tex]

Ok so, 42 ft. by 42 ft.

$25 per square yard

1 square yard = 9 square feet

The total square footage is 1,764 ft.

Total square yards is 196.

The total cost would be $4,900.

Solution:

Step-1: Find the volume of the rectangular prism.

Step-2: Find the volume of the small cube.

Step-3: Divide.

Thus, 560 cubes are needed to fill the rectangular prism.

Answer:

Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.

Answer:

9

27

Step-by-step explanation:

the scale factor of area is 3² = 9

the scale factor of volume is 3³ = 27​

Answer:

32 by using triangle taerem

Answer:

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

Answer:

46 copies I guess

Step-by-step explanation:

253÷5.45 =46

Correct me if i wrong

Answer:

46.422

Step-by-step explanation:

The answer is 46.422 because it's asking for how many copies per minute. And since we know there are 253 copies, we will divide 253 by 5.45. When you divide those you get 46.422

Answer:

Let ABC be a triangle such that CA is produced to meet at E.

We know, an exterior angle of a Triangle is equal to non- adjacent interior angle, so

8x - 10 = x + 15 + 2x + 20

or, 8x - 3x = 35 + 10

or, 5x = 45

or, x = 9

Answer:

The perimeter is the outside of the rectangle

Step-by-step explanation:

You see this by looking at the outside and the answer is 4 by 3

The conditions for inference is not met in the question due to the fact that the large count condition is not met.

This is the condition in statistics that states that the numbers of the successes and the failures have to be greater than 10 for there to be a normal distribution.

Using this formula n(1-p) ≥ 10. The probabilioty is 95%, therefore it would be less than 10

Hi! Hope you are having a nice day!

We are given the slope of the line and its y-intercept.

So, let's find the equation.

The y-intercept is written in the form (0, b).

No worries! b is the y-intercept.

Thus, the y-intercept equals 3.

Now, let's find the equation of the line with a slope of 4 and a y-intercept of 3.

We can write the equation in Slope-intercept form:

y=mx+b, where m stands for the slope and b stands for the y-intercept.

Since we have both m and b, we can just plug the given values:

y=4x+3 ✓

Hope you could understand everything.

Step-by-step explanation:

remember, that a/a = 1, and this is always the "whole" in such fraction scenarios.

in our case here : 9/9 or 3/3.

4 books for 2/9 of his money.

8 books for then 2× 2/9 = 4/9 of his money.

that is together

12 books for 6/9 = 2/3 of his money.

that leaves 3/9 = 1/3 of his money for the 2 identical bags.

so, 1/3 of his money for 2 bags.

how many bags for the whole (3/3) money ?

1/3 × x = 3/3

x = 3

he could have bought 3×2 = 6 bags with the original sum of money.

Answer:

  46 -8i

Step-by-step explanation:

Multiplication of complex numbers is done in a fashion similar to multiplication of any binomials. The difference is that i² = -1, so some terms can be combined.

  (3 -10i)(2 +4i) = 3(2 +4i) -10i(2 +4i)

  = 6 +12i -20i -40i² = 6 -8i +40

  = 46 -8i

Answer:

because it's an odd exponent

Step-by-step explanation:

-2^3 = -(2*2*2)

(-2)^3 = (-2)*(-2)*(-2)

if it was ^4 the sign would be flipped:

-2^4 = -(2*2*2*2) = -16

(-2)^4 = (-2)*(-2)*(-2)*(-2) = 16

The way to put this is that any negative base raised to an odd-numbered power, will result in a negative result, whereas any negative base raised to an even-numbered power, will result in a positive result, with the EXCEPTION of a negative base written WITHOUT grouping symbols. For instanse:

[tex]\displaystyle -1000 = -10^3 \\ -1000 = [-10]^3 \\ \\ BUT \\ \\ 10000 ≠ -10^4\:[-10000 = -10^4] \\ 10000 = [-10]^4[/tex]

I hope you know the differense now, and as always, I am joyous to assist anyone at any time.

Answer:

It is 45 degree angle

Step-by-step explanation:

AB is the tilted angle of the triangle

BC is the height and the vertical part of the triangle

If AB is 10 then BC is 5 and AC is possibly about 6-8

If that is so then 2 right triangles is a square

A square has 90 degree angles on any angle

Divide 90 by 2 which is 45 because a right triangle is half of a square

Therefore angle ABC is 45 degrees

Answer:

18, 19, and 20.

Step-by-step explanation:

Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.
