Answer:

The value of x is 30.

Step-by-step explanation:

The value of x is 30 because 3*30 equals 90 and 90 minus 15 is equal to 75. The total is equal to the angle ST.

Answer:

Step-by-step explanation:

We know that in this case, since this is an intersection, the opposite sides are the same. Therefore, we can make a equation like this:

75 = 3x-15

Then we get:

90=3x

30=x

Solve the system using elimination. 5x + 8y = –29 7x – 2y = –67

Snowcat [4.5K]

7x-2y+-67
multiply both sides of the bottom by 4 and add 5x+8y=-29 
 28x-8y=268

33x=-297
 x=-9 

5(-9) +8y= -29 
-45 +8y =-29 
8y= 16 
y=2

Hi, can you help me answer this question, please, thank you!

Given:

mean, u = 0

standard deviation σ = 1

Let's determine the following:

(a) Probability of an outcome that is more than -1.26.

Here, we are to find: P(x > -1.26).

Apply the formula:

$z=\frac{x^{\prime}-u}{\sigma}$

Thus, we have:

$\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\ \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}$

Using the standard normal table, we have:

NORMSDIST(-1.26) = 0.1038

Therefore, the probability of an outcome that is more than -1.26 is 0.1038

(b) Probability of an outcome that

Which relation does not represent a function

Nastasia [14]

Answer:

For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
