Describe the error made in subtracting the two

Mathematics

5 0

Answer:

You must subtract all terms of the numerator being subtracted out, not just the first term.

The negative 2 should have been subtracted out to get a numerator of x+1-x+2

The simplified numerator of the difference should be 3, not –1.

The distribution of bladder volume in men is approximately normal with mean 550 ml and standard deviation 100 ml. what percent o
ruslelena [56]

To solve this, we use the z-test.

z = (x – u) / σ

when x = 450

z = (450 – 550) / 100

z = -1

 

We use the standard distribution tables to find for P.

P = 0.1587

 

Since we are looking for values greater than x = 450, therefore:

1 – 0.1587 = 0.8413

 

This means that 84.13% have bladder volume larger than 450 mL.

Using prime factorization what is the GCF 3y 2 squared, 24y 3 cubed
WINSTONCH [101]

Answer:

3y^2

Step-by-step explanation:

Given:

To find the GCF of 3y^2\ and\ 24y^3 using prime factorization.

Writing each in prime factors:

3 = 1 \times <u>3</u>

24 = 1 \times 2 \times 2 \times2 \times <u>3</u>

Now, GCF of 3 and 24 is 3

y^2=1\times y\times y

y^3=1\times y\times y\times y

GCF of y^2 and y^3 is y\times y=y^2.

Therefore, the overall GCF of the two terms is 3y^2
