How many months of the year have 31 days?  Jan, Mar, May, Jul, Aug, Oct, Dec.  That's 7 months out of 12.  Thus, if you were to pick a month from these 12, the chances that you'd pick one that had 31 days would be 7/12, or approx. 0.58.

e-lub [12.9K]
FICA or Federal Insurance Contributions Act is composed of social security tax and medicare tax. Hence, we need to add these taxes to get the FICA tax.Social Security Tax is = 6.2%Medicare Tax is = 1.45%
Social Security Tax = 36,038*.062 = 2,234.356         Medicare Tax = 36,038*.0145 = 522.552
2,234.356 + 522.552 = 2,756.907 or 2,756.91
Therefore, Elias paid B.) 2,756.91 as FICA tax for the year.

what is the slope-intercept form of the equation of a line that passes through (5, -4) and has a slope of 3/4?
Troyanec [42]
Y = mx + b
slope(m) = 3/4
(5,-4)...x = 5 and y = -4
now we sub
-4 = 3/4(5) + b
-4 = 15/4 + b
-4 - 15/4 = b
-16/4 - 15/4 = b
- 31/4 = b....or - 7 3/4 = b

so ur equation is : y = 3/4x + (-31/4) or y = 3/4x - 31/4
