It's A.
All you need to do is plug in the X from the ordered pair, then solve.
y=-5x-4
y=-5(10)-4
y=-50-4
y=-54
Which is NOT -52, so the answer is indeed A
therefore, the sum of this infinite geometric series can be calculated using the formula .
So,
If 2 is the sum of this infinite series, then you'll never reach it.
Answer:
She only has 120 croat
Step-by-step explanation:
We can use a ratio to solve
She only has 20 dollars
1 dollar 20 dollars
---------- = --------------
6 croat x croat
6*20 = x
120 =x
120croat
She does not have enough money
She needs 138 croat
Answer:
(0.4593, 0.5073)
Step-by-step explanation:
The first thing we must do is calculate p:
p = 580/1200 = 0.4833
now 90% confidence interval is given by:
p + - (z alpha / 2) * (p * (1-p) / n) ^ (1/2)
Now, at 90% confidence level the t is:
alpha = 1 - 90% = 1 - 0.90 = 0.10
alpha / 2 = 0.10 / 2 = 0.05
z (0.05) = 1.645
replacing these values we are left with:
p + - (1.645) * (0.4833 * (1- 0.4833) / 1200) ^ (1/2)
0.4833 + - 0.024
the interval would be:
0.4833 + 0.024 = 0.5073
0.4833 - 0.024 = 0.4593
(0.4593, 0.5073)
