The answer for your question is 1850 BCE
THE ANSWER IS B
A: 1/3*6,000,000 does NOT equal 18,000,000
C: However, 2/5*6,000,000 does equal 2, yet, $2.4*10^3 is a FALSE STATEMENT and it doesn't make sense
D: Not ALL statements are correct
Answer:
3d + 4w
Step-by-step explanation:
Since there are multiple of each variable, we can add like terms.
There are 3 d's, so adding these together gets you 3d
There are 4 w's, so this is equal to 4w.
Now, add these together to get the equivalent expression:
3d + 4w is the expression
21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
We can solve this problem by referring to the standard
probability distribution tables for z.
We are required to find for the number of samples given the
proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value
of z equivalent to:
z = 1.96
Since the problem states that it should be within the true
proportion then p = 0.5
Now we can find for the sample size using the formula:
n = (z^2) p q /E^2
where,
<span> p = 0.5</span>
q = 1 – p = 0.5
E = estimate of 5% = 0.05
Substituting:
n = (1.96^2) 0.5 * 0.5 / 0.05^2
n = 384.16
