If you’re having trouble with your nines times table use the finger trick. But it only works for 9x1-9-10 so hold up your hands in front of you and your palms facing towards you. Since you’re using 9x9 put your ninth finger down and the amount of fingers on your left would be the amount of tens so their would be 8 tens meaning 80 and the amount of fingers on the right side of the finger that is down would be the ones so there is one finger on the right. After that, you can just add them up. 80+1= 81 if you need another example just comment on this and say if you’re confused.:)

If Free Yer Assets Bank (FYAB) will give you 0.25% compounded quarterly and I.M.A.Q.T.π bank will give you 0.23% interest compou
ivann1987 [24]

Answer:

FYAB gives a better deal.

Step-by-step explanation:

Compound interest:

A = P(1 + \dfrac{r}{n})^{nt}

Continuously compounded interest:

A = Pe^{rt}

For the quarterly compounded interest, r = 0.25%, and n = 4.

2P = P(1 + \dfrac{0.0025}{4})^{4t}

1.000625^{4t} = 2

\log (1.000625^{4t}) = \log 2

4t(\log 1.000625) = \log 2

t = \dfrac{\log 2}{4\log 1.000625}

t = 277

For the continuously compounded interest, r =0.23%

A = Pe^{rt}

2P = Pe^{0.0023t}

2 = e^{0.0023t}

\ln 2 = \ln e^{0.0023t}

\ln 2 = 0.0023t

t = \dfrac {\ln 2}{0.0023}

t = 301

The quarterly compounded doubles in 277 years.

The continuously compounded doubles in 301 years.

Answer: FYAB gives a better deal.

 that makes the  equation of the line perpendicular to it to be -1 / (1/6) = -6 

the general equation in point slope form is 

y-y1 = m(x-x1)    where m=slope and (x1,y1) = point on the line

so here we have:-

y - 23 = 6(x -(-3)

y - 23 = 6x + 18

y = 6x + 41    

thats the answer

The probability that z is greater than -1.8
Lerok [7]

Answer:

0.964

Step-by-step explanation:

It's easier to approach this problem if you find the prob. that z is less than -1.8 and then subtract your result from 1.00.

The prob. that z is less than -1.8 can be found using any calculator with probability and statistic functions.

The prob. that z is less than -1.8 = normcdf(-100,-8) = 0.036.  Here "cdf" stands for "cumulative probability density function)," -100 is far to the left of z = -1.8, and the result (0.036) is the area under the standard normal probability density curve to the left of z = -1.8.

Finally, subtract this 0.036 from 1.000, obtaining 0.964.  This is the probability that z is greater than -1.8.
