The value of x is :

  • - 8

\large \boxed{ \mathfrak{Explanation}}

let's solve ~

  • x - 17 =  - 25

  • x =  - 25 + 17

  • x =  - 8

To solve this, add 17 to both sides:
x = -25 + 17
x = -8

Which function rule describes the pattern in the table?
lakkis [162]

The correct answer is B.

In order to prove which of the function rules provided is the one corresponding to the schedule represented by the table, the different y-values need to be sustituted in the function rules. <u>Only the correct function rule will yield the corresponding x-value. </u>

<u>Let's prove that option B is the correct one</u>

FUNCTION B y= 5x - 14

  • If x= -4 --> substituting: 5(-4) - 14= -20 - 14= -34 therefore, y= -34 <u>CORRECT</u>
  • If x= -1 --> 5(-1)-14 = -5 - 14= -19 therefore y= -19 <u>CORRECT</u>
  • If x= 2 --> 5(2) - 14=  10-14= -4, therefore y= -4 C<u>ORRECT</u>
  • If x= 4 --> 5(4)-14= 20-14= 6, therefore y=6<u> CORRECT</u>
  • If x= 7 --> 5(7) -14= 35-14= 21, therefore y=21 <u>CORRECT</u>

Suppose commute times in a large city are normally distributed and that 63.70% of commuters in this city take more than 22 minut
USPshnik [31]

Answer:

The mean is 24.205

Step-by-step explanation:

Firstly, we need to get the z-score

From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way

So the probability we had was;

P( x > 22)

So we need the z-score corresponding to 63.70% or simply 0.637

We can use the standard normal distribution table to get this

Mathematically, from the standard normal distribution table this is -0.35

z-score = (x- mean)/SD

-0.35 = (22-mean)/6.3

22-mean = -2.205

mean = 22 + 2.205 = 24.205

The heights of a group of boys and girls at a local middle school are shown on the dot plots below.
sukhopar [10]

You get this answer from identifying the numbers, seeing if there is any number that is larger or shorter than 40-60.

Hope this helped!
