Answer: 0.28
Step-by-step explanation:
Binomial probability formula :
, where x = Number of success , n= sample size , p= probability of success for each trial.
Let x = Number of hens lay eggs.
then, p= 0.80
n= 12
For x=10
Hence, the required probability = 0.28
18) Seven less than the product of a number z and 3 is equal to 4
Product of a number z and 3 ⇒ 3z
Seven less than^ ⇒ 3z - 7
Equal to 4 ⇒ = 4
3z - 7 = 4

19) Make an equation for this problem. Your equation will look like:
d + 132 = 468, where d + 132 is the distance she drove on Monday and 468 is the distance she drove on Tuesday.
Solve the equation for d by subtracting 132 from both sides.
d = 336
The truck driver drove 336 miles on Monday, so that means she did not drive 600 miles on Monday.
You can express 0.000036 as 3.6 × 10^-5 (we move the decimal 5 places left)
Then we find 3.6 × 10^-5 × 20.5 × 10^7
The exponents add to become just 10^2.
3.6 × 20.5 = 73.8
73.8 × 10^2 is our answer...
In proper scientific notation, this is 7.38 × 10^3. (the left # should be <10)
In standard notation, this is 7380. (we move the decimal 3 places right)
Answer:
1/4
Step-by-step explanation:
Let's find the value of c.
1 2^2 1
2^(-4)*2^2 = c = --------- * -------- = -------- = 1/4
2^4 1 2^2
this result matches the fourth given possible answer choice.
