We have to figure out what the product of DA is,

We know that,

So,



So the solution is,

Hope this helps :)
2/5 as
5 - 7/1 - 6 = -2/-5. Dividing a negative number by a negative gives you a positive so 2/5.
1. let x = a number
x^2+5
2. let x = a number
2x-(x+19)
3. let x = a number
2x=1/3x + 9
4. let x = 1st integer
x+1 = 2nd integer
x+2 = 3rd integer
(x+x+1+x+2)/4
=(3x+3)/4
5. let x=smallest integer
x+1 = 2nd integer
x+2 = 3rd integer
x+3 = largest integer
x+x+1+x+2+x+3 = 9(x+3)
= 4x+6= 9x+27
Answer:
CI ≈ (173.8 < μ < 196.2)
Step-by-step explanation:
We are told that laboratory tested twelve chicken eggs. Thus;
n = 12
Mean; x¯ = 185 mg
S.D; s = 17.6 mg
DF = n - 1 = 12 - 1 = 11
We have a 95% confidence level. Thus; α = 0.05
Since n < 30, we will use t-sample test.
Thus, from t-table attached at 95% Confidence level and DF = 11, we have;
t = 2.201
Thus,formula for Confidence interval is;
CI = (x¯ - t(s/√n)) < μ < (x¯ + t(s/√n))
CI = (185 - 2.201(17.6/√12)) < μ < (185 + 2.201(17.6/√12))
CI = (185 - 11.1825) < μ < (185 + 11.1825)
CI = (173.8175 < μ < 196.1825)
CI ≈ (173.8 < μ < 196.2)
Answer:
v=3
Step-by-step explanation:
141=-v-8(-8v+6)
distribute -8 into the parentheses
141=-v+ 64v-48
simplify by putting v's together
141=63v-48
add 48 to both sides to get x by itself
189=63v
divide both sides to isolate x
v=3
