765,000 should be the correct answer
Answer:
Andrew
Step-by-step explanation:
Abby:
Since red cards are negative, a red 9 would represent the number -9. And because black cards are positive, a black 6 would represent the number 6. To get the sum, we add the two numbers together:
-9 + 6
That gives us a total of -3.
Ashley:
We can do the same thing as before. A black seven would represent 7 and a red 8 would represent -8. Next we again add them together:
7 + (-8)
That gives us a total of -1.
Andrew:
The red 4 is -4, while the black 4 is 4:
-4 + 4
That gives us a total of 0.
Anna:
Anna has a red 8 which represents -8 and another red, a three, which would represent -3. We can add the two to get:
-8 + (-3)
That gives us a total of -11.
In all, Andrew has the highest sum of 0, which means he won the game.
Answer:
Step-by-step explanation:
Given that in a randomized controlled trial in Kenya, insecticide treated bednets were tested as a way to reduce malaria. Among 343 infants using bednets, 15 developed malaria. Among 294 infants not using bednets, 27 developed malaria.
H0: p1=p2
H1: p1 <p2
(one tailed test)
p1 = 15/343:p2 =27/294:
Difference 4.813 %
95% CI 0.9160% to 9.0217%
Chi-squared 5.947
DF 1
Significance level P = 0.0073
Since p <0.01 we reject null hypothesis.
The answer is 12 5/18 hope it helps
Answer:
9 mph
Step-by-step explanation:
-let x be the speed of current and t be time. The speed equation for both directions can then be represented as:
#Since t is equal in both, we can do away with t.
#We the divide the downstream equation by the upstream equation as:
Hence, the boat's speed in still water is 9 mph
