5−(2w−8)=6w−9
Show Steps
Expand 5−(2w−8): −2w+13
−2w+13=6w−9
Subtract 13 from both sides
−2w+13−13=6w−9−13
Simplify
−2w=6w−22
Subtract 6w from both sides
−2w−6w=6w−22−6w
Simplify
−8w=−22
Divide both sides by −8
−8w
−8 =

Answer:
(B) 0.0588
Step-by-step explanation:
The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:
Because the deck has 52 cards and 13 of them are diamonds.
Then, if the first card was diamonds, the probability that the second card is also diamond is:
Because now, we just have 51 cards and 12 of them are diamonds.
Therefore, the probability that both cards are diamonds is calculated as a multiplication between 
and 
. This is:
Answer:
16
Step-by-step explanation:
Use PEMDAS (Parenesis, Exponents, Mutiplication, Division, Addition, Subtraction)
Using PEMDAS we add 5+3 for it is in parenesis. We get 8 from that. Finally, we multiply 8 with 2 to get 16.
Answer:
Step-by-step explanation:
From the given information:
We are to find the following:
1)
Directional hypothesis: The directional hypothesis is the groups with different bedroom lightning conditions having a different proportion of eyesight proportions.
2)
The non directional hypothesis is each group having the same proportion of eyesight problems regardless and independent of the condition of the bedroom lightning.
3)
Control group: Children that slept in darkness
4)
Experimental groups: Children that slept in night light and those that slept with lamp.
5)
Independent variable: Light condition of the bedroom
Dependent variable: Eye sight problem.
