What does this mean plz tell
Answer:
a = 0.05
Claim: The success rate of the XSORT method of gender selection.
x = 55
n = 100
Null and alternative hypothesis is
H0:P=0.5 Vs P 0.5
p0 : 0.5
x : 55
n : 100
prop : p0
calculate
we get
z = 1
p = 0.317310
so p value > 0.05 we fail to reject null hypothesis.
Conclusion : There is sufficient evidence that we support null hypothesis.
That is the success rate of the XSORT method of gender selection
I hope that 2-1 means 21.
DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2
You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer.
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.
Minus means subtraction.
Plus means addition.
Divided means division.
Two hundred fifty nine minus eighty five plus sixty two divided by two:
259 - 85 + 62 / 2
Solution:
259 - 85 + 62 / 2
259 - 85 + 31
174 + 31
205
Best of Luck!
Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = = 60
