If a data set has mean of 150 and a standard deviation of 25, what is the z-score of an element with a value of 250?

1 answer:

5 0

Answer:

Z-score is 4

Step-by-step explanation:

N(150, 25^2)

Use z-score formula (can be found from internet with miu and sigma symbol)

$z = \frac{250 - 150}{25} \\ z = \frac{100}{25} \\ z = 4$

Answer:

B= $\left[\begin{array}{ccc}0&0\\0&1\\\end{array}\right]$

Step-by-step explanation:

Let's do the multiplication AB.

If A= $\left[\begin{array}{ccc}1&0\\0&0\\\end{array}\right]$

then the first row of A is= (1 0) by the first column of B= (0 0) is equal to zero.

the first row of A is= (1 0) by the second column of B= (0 1) is equal to zero too because 1.0+0.1=0.

the second row of A is= (0 0) by any colum of B is equal to zero too.

So we have found an example that works!

1. iThis is shaped like a V with its vertex at the point (0,5)
( its ( 1,7)

2. -3 <= -1-1 = =2

so its (-1, -3)

Round to the nearest thousands

8,276 = 8,000
2,451 = 2,000

8,000 + 2,000 = 10,000

Answer

It takes two steps to solve this problem. Step 1, you must solve the binomial squared. Then combine similar terms.
