Ray FL bisects ∠AFM. m∠LFM = (11x+4), m∠AFL = (12x - 2).

Ne4ueva [31]

Answer:

AFM = 140

LFM = 70

Step-by-step explanation:

Here, we are to calculate LFM and AFM

Since AFM was bisected, then LFM + AFL is AFM

and also AFL = LFM

Thus;

11x + 4 = 12x -2

12x-11x = 4 + 2

x = 6

AFM = AFL + LFM = 11x + 4 + 12x-2 = 23x + 2

Substitute x = 6

AFM = 23(6) + 2 = 140

LFM = 11x + 4 = 11(6) + 4 = 66 + 4 = 70

How much does he/she pay with 10 %

ss7ja [257]

Answer:

5085

Step-by-step explanation:

price after discount is 5000- 10% of 5000 = 4500

V.A.T = 13% of 4500 = (13/100)*4500= 13*45= 585

Price after V.A.T = 4500 + 585 = 5085

Pavlova-9 [17]

Answer:

Mean = 3.4

Variance = 1.088

Standard deviation = 1.0431

Step-by-step explanation:

$P=0.68\\ \\N=5$

The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is $m=N\cdot p$

Thus,

$m=5\cdot 0.68=3.4$

The variance of the binomial distribution is $s^2=Np(1-p)$ , where $s^2$ is the variance of the binomial distribution, so

$s^2=5\cdot 0.68\cdot (1-0.68)=3.4\cdot 0.32=1.088$

The standard deviation $s$ is the square root of the variance $s^2,$ so

$s=\sqrt{1.088}\approx 1.0431$

The campers in cabin A walked 1/4 of the way to otter ridge (13 miles) How many miles did they walk?

shusha [124]

The question demands that we find a fraction of a given quantity.

The 'of ' means multiplication.

So the total distance of the journey was

$13 \: miles$

But they walked ¼ of the whole journey. We are supposed to find

$\frac{1}{4} \: of \: 13 \: miles$
$\\= \frac{1}{4} \times 13 \: miles$

$= \frac{13}{4} \: miles$

$= 3.25\: miles$

Hence they walked 3.25 miles.
