You need to divide 6 from 2,600 then make the diagram
Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )
Answer:
The correct answer: 0.05404
Step-by-step explanation:
Given:
Binomial distribution = x
n = 10
and p = 0.09
solution:
P(X=x) =1 0Cx*(0.09^x)*((1-0.09)^(10-x)) for x=0,1,2,...,10
So the probability is calculated by the Formula:
P(X>=3) = 1-P(X=0)-P(X=1)-P(X=2)
putting the given values in the formula
= 1-10C0*(0.09^0)*((1-0.09)^(10-0))-...-10C2*(0.09^2)*((1-0.09)^(10-2))
= 0.0540400
Thus, the correct answer: 0.05404
Answer:
5 bags
Step-by-step explanation:
Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags
The above provides 10pounds of potting soil already
Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil
We know that 1 bag contains 5/8 pounds of potting soil
x bags contain 3 pounds of potting soil
On cross multiplication we get
x = 
since x is an integer x = 5 bags
Note that an extra amount of soil will be remained unused
You would plug the numbers into the midpoint formula and solve to get the midpoint (3, -5).
Hope this helps!
