Answer: x=k+c/4
Step-by-step explanation:
4x-c=k
<u>Add c to both sides.</u>
4x=k+c
<u>Divide both sides by 4.</u>
x=k+c/4
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Answer:
12
Step-by-step explanation:
3 divided by .25 equals 12. You move the decimal of 25% twice to the left to get .25.
Answer:35
Step-by-step explanation:
The values of son 360°, cos 360°, tan 360° are the same as the values of:
sin 0°, cos 0°, tan 0°:
sin 360° = sin 0° = 0
cos 360° = cos 0° = 1
tan 360° = tan 0° = sin 0° / cos 0° = 0 / 1 = 0
The confidence interval is
.
This means that if we take repeated samples, 99% of the intervals would contain the population proportion.
To construct this interval, we use
,
where
Since 590/1016 said they had a cat and a dog, p=0.581 and N=1016:
We need the z-score associated with this confidence level:
Convert 99% to a decimal: 99/100 = 0.99
Subtract from 1: 1-0.95 = 0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table, we see that this value is equally distant from z=2.57 and z=2.58, so we will use z=2.575:
