Heyaa!! My name is Pinky and im here to tell you that the answer is..

Step-by-step explanation:

!!(b) P( x < 4) = ( 5 + 10 + 2 + 9 ) / ( 5 + 10 + 2 + 9 + 33 + 12 + 15 + 3 + 1 ) = 13/45!!

!!(c) P(x = 6) = 15 / (5 + 10 + 2 + 9 + 33 + 12 + 15 + 3 + 1) = 1/6!!

!!(d) P( x ≥ 5 ) = (12+ 15 + 3 + 1) / (5 + 10 + 2 + 9 + 33 + 12 + 15 + 3 + 1) = 7/30!!

Have and Amazing Day now!!

FCD=x+41, BCF=x+78, BCD=95. Find x

Lorico [155]

You'll set the two expressions equal to 95.
So 2x+119=95
Then 2x=-24
Finally x=-12

Solve the equation for x. 1 6 (2x − 12x) = 30 A) −12 B) −15 C) −18 D) −24

lubasha [3.4K]

$\frac{1}{6}$ *(2x-12x) = 30

$\frac{1}{6}$ *(-10x) = 30

$\frac{-10}{6}$ x = 30

$\frac{-5}{3}$ x = 30

$\frac{5}{3}$ x = -30

x = -30/ $\frac{5}{3}$ = -30 * $\frac{3}{5}$

x = -18

the correct answer is C

One of the roots of the quadratic equation 4mnx^2 – 6m^2x – 6n^2x + 9mn = 0 (m, n ≠ 0) is a)-3m/2n b)3m/2n c)2m/3n d)-2m/3n

maxonik [38]

Answer:

$B.\ \frac{3m}{2n}$

Step-by-step explanation:

Given

$4mnx^2 - 6m^2x - 6n^2x + 9mn = 0\ (m, n \neq 0)$

Required

Calculate one of the root of the equation

$4mnx^2 - 6m^2x - 6n^2x + 9mn = 0$

Factorize

$2mx(2nx - 3m) -3n(2nx - 3m) = 0$

$(2mx - 3n)(2nx - 3m) = 0$

Split equation

$2mx - 3n = 0\ or\ 2nx - 3m = 0$

Make x the subject of formula in both expressions

$2mx = 3n\ or\ 2nx = 3m$

$x = \frac{3n}{2m}\ or\ x = \frac{3m}{2n}$

<em>From the list of given options, one of the roots of the equation is</em> $\frac{3m}{2n}$

A times a to the 7 power

ivolga24 [154]

Answer:

${a}^{8}$

Step-by-step explanation:

a is a¹ and you have a^7 in multiplication you add the exponents. If you were to have a numerical value, you would replace a and calculate. If a = -5 then: a^8 =

$( - 5)^{8}$

which is = 390 625
