Answer:
X = 4, 3
Step-by-step explanation:
I don't know if that's what you were looking for
Sample proportion: 190/425 = 0.45
ME = 1.96*sqrt[0.45*0.55/425] = 0.047
-----
95% CI: 0.45-0.047 < p < 0.45+0.047
I believe it's C.
(Hint: y=mx+b)
M is Slope and B is Y-Intercept.
(6,-9) bc downwards means (-) so -3-6=-9
Answer:
Step-by-step explanation:
The two different rentals give rise to two equations. Let t and c represent the rental costs of a table and chair, respectively. The rentals are ...
5c +2t = 23
3c +8t = 58
Cramer's rule tells you ...
c = (2·58 -8·23)/(2·3-8·5) = -68/-34 = 2.00
t = (23·3 -58·5)/-34 = -221/-34 = 6.50
The cost to rent each chair is $2.00.
The cost to rent each table is $6.50.
_____
<em>Cramer's Rule</em> says the solution to
ax +by = c
dx +ey = g
is ...
x = (bg -ec)/(bd -ea)
y = (cd -ga)/(bd -ea)
When the equation's coefficients are not convenient to achieve elimination of a variable, Cramer's rule can get to the solution very quickly. The same number of math operations are involved, but they are expressed in terms of a formula that can be used with no guesswork.
