weeks she can make withdrawals from her account.
Answer:
400-40x x=6
Step-by-step explanation:
400 in total. minus 40 each week (x)
40 × 6= 240
400-240=160
Answer:
95% confidence interval for adults in age group 18-29 is (-0.007, 0.107)
Step-by-step explanation:
Given
N1 = n2 = 500
% of males = 0.30
% of females = 0.35
95% confidence interval
(p2-p1) + z(0.025) sqrt (p1q1/n1 + p2q2/n2) and (p2-p1) - z(0.025) sqrt (p1q1/n1 + p2q2/n2)
Substituting the given values, we get –
(0.35-0.30) + 1.96 sqrt (0.3*0.7/500 + 0.35*0.65/500) and (0.35-0.30) - 1.96 sqrt (0.3*0.7/500 + 0.35*0.65/500)
0.05 + (1.96 *0.029) and 0.05 - (1.96 *0.029)
0.05 + 0.057 and 0.05 – 0.057
(-0.007, 0.107)

Solve each equation for x.
(a) ln(3x − 17) = 5
Express the given quantity as a single logarithm.
ln(a + b) + ln(a − b) − 5 ln(c)
Using exponential and logarithmic functions, it is found that:
a) The solution of the inequality is .
b) The solution of the inequality is
a) The solution to the equation is x = 55.14.
As a single logarithm, the expression is:
Inequality a:
Applying the exponential to both sides:
Hence, in interval notation:
Inequality b:
Applying ln to both sides:
Hence, in interval notation, the solution is:
Equation a:
The quantity given is:
To express as a single logarithm, these following properties are applied:
Hence:
As a single logarithm, the expression is:

Answer:
(a) ln(x) = 0
Then 0 < x < 1
(b) e^x > 2
Then ln2 < x < ∞
(a) ln(3x - 17) = 5
x = 55.1377197
ln(a + b) + ln(a - b) - 5ln(c)
= ln[(a² - b²)/c^5]
Step-by-step explanation:
First Part.
(a) ln(x) < 0
=> x < e^(0)
x < 1 ....................................(1)
But the logarithm of 0 is 1, and the logarithm of negative numbers are undefined, we can exclude the values of x ≤ 0.
In fact the values of x that satisfy this inequalities are between 0 and 1.
Therefore, we write:
0 < x < 1
(b) e^x > 2
This means x > ln2
and must be finite.
We write as:
ln2 < x < ∞
Second Part.
(a) ln(3x - 17) = 5
3x - 17 = e^5
3x = 17 + e^5
x = (1/3)(17 + e^5)
= 55.1377197
Third Part.
We need to write
ln(a + b) + ln(a - b) - 5ln(c)
as a single logarithm.
ln(a + b) + ln(a - b) - 5ln(c)
= ln(a + b) + ln(a - b) - ln(c^5)
= ln[(a + b)(a - b)/(c^5)]
= ln[(a² - b²)/c^5]
