Answer:
5
Step-by-step explanation:
Since we have not instructed to follow any kind of rule dividing, we can write in any form. Let's calculate it using fraction
We can multiply both the nominator and denominator with 100
The answer is 5.
We can also solve it as a division of fractions:
Well 57+59+61= 177 so the answer is 57
The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11
Hello there!
Your answer would be
CAT (top line) = DBU (bottom line)
CAT (bottom line) = BZS (top line)
Hope I helped!

Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
