We have , to find inverse switch y and x then solve for y.
.
Hope this helps.
The "divisor" in synthetic division is most conveniently the value of the zero of the binomial term. Here, that is x=5. You also need to make sure you include all of the coefficients in the "dividend", putting zero where terms are missing.
The appropriate choice is
A.
925 rounded to the nearest hundred is 900 becuase first we identify the hundreds digit which in this case is 9.
Second,we identify the next smallest place value (the digit to the right of the hundreds place) which in this case is 2.
Is that digit greater than or equal to five? No - we round Down.
The hundreds digit is stays the same but every digit after it becomes a zero.
Keep in mind, repeating number is rational
Answer:
1st: 17.43(repeat 43) +√49 : rational
4th: √64 + 6/11: rational
Answer:
We reject H₀. We accept Hₐ (the cream can improve the the skin of more than 50%
Step-by-step explanation:
We have a proportion one tail test (right)
P₀ = 50 % = 0,5
P = 44/53 = 0.831
sample size = n = 53
Confidence interval = 0,95 α = 0.05 then z(c) = 1.64
1.-Hypothesis
H₀ null hypothesis P₀ = 0.5
Hₐ alternative hypothesis P₀ > 0.5
2.-Compute z(s)
z(s) = ( P - P₀ ) / √P₀Q₀/n ⇒ z(s) = (0.831 - 0.5 )/√0.5*0.5/53
z(s) = 0.3301/0.06
z(s) = 5.5
3.-Compare z(c) and z(s)
z(s) > z(c) 5.5 > 1.64
therefore z(s) is in the rejection region we reject H₀ . And accept Hₐ
