Answer:

  • See below

Step-by-step explanation:

  • 1. c increased by 5 is 5                       ⇒ h. c + 5 = 5
  • 2. 4 more than a number is 12           ⇒ b. n + 4 = 12
  • 3. The product of 4 and n is 12          ⇒ i. 4n = 12
  • 4. The difference of 27 and k is 15    ⇒ a. 27 - k = 15
  • 5. 8 less than 3 times x is 10              ⇒ f. 3x - 8 = 10
  • 6. 3 times x increased by 8 is 20      ⇒ d. 3x + 8 = 20
  • 7. A number minus 8 is 3                   ⇒ e. k - 8 = 3
  • 8. Three times a number is 9            ⇒ j. 3n = 9​
  • 9. Twice a number plus 1 is 11           ⇒ g. 2x + 1 = 11
  • 10. 6 less than a number is 5            ⇒ c. c - 6 = 15

Which box plot represents the data?<br><br> 135, 149, 156, 112, 134, 141, 154, 116, 134, 156
Keith_Richards [23]
To get the box plot we begin by arranging the data in ascending order:
<span>135, 149, 156, 112, 134, 141, 154, 116, 134, 156
rearranging we get:
112,116, 134, 134, 135, 141, 149, 154, 156, 156
then:
Lower value=112
Q1=134
Median=(135+141)/2=138
Q3=154
Largest value=156

The second figure is the correct figure.

Danika concludes that the following functions are inverses of each other because f(g(x)) = x. Do you agree with Danika? Explain
arsen [322]
We cannot agree with Danika. Why? Well, The reasoning is given as follows:

Two functions are inverses of each other if and only if it is true that the composition function is given by:

f(g(x))=x

Everything is ok up to this point, right?. But let's prove that this is not fulfilled for these functions, then:

f(x)=\left | x \right | \\ \\ g(x)=-x \\ \\ f(g(x))=\left| -x \right |=\left | -1 \right | \left | x \right |=\left | x \right |  \\ \\ \therefore f(g(x))=\left | x \right | \neq x
<span>
As you can see we did not obtain the function that matches the definition of </span>inverse functions. For that reason <em>we can't agree with Danika</em>.

Let W be the event that a randomly chosen person works for the city government. Let V be the event that a randomly chosen person
Yuki888 [10]

Answer:

We can express that probability as P(V | W), the probability of V given W.

Step-by-step explanation:

We know that the chosen person works for the goverment, so we have to assume W as hypothesis. Therefore, in order to calculate the probability of that person voting on the election, event noted by V,  we have to <em>condition</em> V to the event W. As a result, we want the probability of V given W, which can be written as P(V | W), and it can be calculated using this formula

P(V | W) = P(V \cap W) / P(W)

Without calculating, explain how many decimal places are in the product 0.6 X0.4 X 1.9. Rewrite the expression as the product of
Vladimir79 [104]
There's only one decimal point in the answer. This is quite obvious. Regardless of whether or not your adding, subtracting, dividing, or multiplying, there's really only going to be one decimal, ever. This doesn't change, However, what DOES change are decimal PLACES.

Looking at the problem, you see both .6 and .4 are placed to the right of the decimal, otherwise known as the tenths place (1/10). 

Looking at 1.9, you see you have one number (1) placed to the left of the decimal, the ones place, and another number placed to the right of the decimal (9), in the tenths place. 

Well, this is simple. You can look and see that your multiplying fractions against a whole number, which will of course make this whole number even smaller. By how much though??

Well, you can really tell this by looking at how MANY numbers are behind the decimal. You have .9, .4, and .6

That's 3 numbers behind the decimal place. This may not help you solve the problem itself, but this tells you here (ignoring the 1, that will be taken out immediately while solving and turned into a 0) that you will have 3 numbers placed from the tenths place all the way to the thousandths place.

Basically, this tells you that you'll have three decimal places to the right of the decimal. 

As for rewriting your problem to better show this, that's simple too.

All you have to do is simple multiplication, just in the tenths place. How? You know that 6*4 (referring to .6 and .4) is 24, that means that .6*.4 will be .24

How does this support your answer before? .24 has TWO numbers to the right of the decimal. That's TWO decimal places. With the .9 in 1.9, that's still THREE decimal places to the right of the decimal, and your answer would be the same.

So, here's it re-written.
1.9*.24=X

~Hope this helps!
