Answer: 31.4 mm
Step-by-step explanation:
C=2πr
2(3.14)(5)
2(15.7)
31.4
First, determine the annual effective interest based on the annual interest and the compounding,
ieff = (1 + i/m)^m - 1
Substituting,
ieff = (1 + 0.03/12)^12 - 1 = 0.0304
To determine the future worth (F) of the current investment (P) is,
F = P(1+ieff)^n
Substituting all the known values with n unknown,
3000 = 175(1 + 0.0304)^n
Solving for n gives an n = 94.8867 years
Among the choices, the nearest value is 94.8377 years.
Answer:
B.
Step-by-step explanation:
factored form actually contains the x intercepts right in it. Basically whatever sets the whole equation equal to zero.
On the graph you can see that it passes through both positive and negative 4. so (x+4)(x-4) is the answer because plugging in 4 for x will make it zero. Same for plugging in negative 4
Hope this helps!
Answer: The y-intercept is 1
Step-by-step explanation:
On a graph, the y-intercept is the point where the line intersects the y-axis. The corresponding x-coordinate is always 0. ... When a linear equation is written in slope-intercept form (y=mx+b), the slope is represented by the variable m. It is the coefficient to x in the equation.
Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%
Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)
Answer: The 90% confidence interval is (7.38, 6.38)
