Simplify 5+2i/6+i

nlexa [21]

Given problem is $\frac{(5+2i)}{(6+i)}$

To simplify that we need to multiply and divide by conjugate of the denominator

conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part

Now multiply and divide by 6-i

$=\frac{(5+2i)}{(6+i)}\cdot\frac{(6-i)}{(6-i)}$

$=\frac{30-5i+12i-2i^2}{36-6i+6i-i^2}$

$=\frac{30+7i-2i^2}{36-i^2}$

$=\frac{30+7i-2\left(-1\right)}{36-\left(-1\right)}$

$=\frac{30+7i+2}{36+1}$

$=\frac{32+7i}{37}$

$=\frac{32}{37}+\frac{7}{37}i$

Hence final answer is $\frac{32}{37}+\frac{7}{37}i$

Find the area under the standard normal curve between z = −2.57 and z = 1.27. Round your answer to four decimal places, if neces

dexar [7]

P(-2.57 ≤ Z ≤ 1.27) = P(Z ≤ 1.27) - P(Z ≤ -2.57)

P(Z ≤ 1.27) = 0.8980
P(Z ≤ -2.57) = 1 - P(Z ≤ 2.57) = 1 - 0.99488 = 0.00512

P(-2.57 ≤ Z ≤ 1.27) = 0.8980 - 0.00512 = 0.89288
0.8929 (4 d.p.)

Write 3.242424... as a mixed number.

victus00 [196]

Answer:

$3\frac{8}{33}$

Step-by-step explanation:

3.242424.....

This number can be written as 3 + 0.242424....

We convert the decimal part into fraction

Let x= 0.242424......

Multiply both sides by 100

100x = 24.2424....

x= 0.2424.....

------------------------------------- (subtract it)

99x = 24

Divide both sides by 99

So x= 24/ 99

simplify the fraction

$\frac{24}{99} =\frac{8}{33}$

3.242424... can be written as 3 + 0.242424....

Replace the fraction for decimal

So final answer is $3\frac{8}{33}$
