The difference between a number divided by 3 and 4 is 20

Rzqust [24]

Set the number to x.

$\frac{x}{3}-\frac{x}{4}=20$
$\frac{4x}{12}-\frac{3x}{12}=20$
$\frac{x}{12}=20$
$x=240$

Thus, the number is 240.

Suppose your statistics instructor gave six examinations during the semester. You received the following grades (percent correct

zheka24 [161]

Answer:

15 samples

Step-by-step explanation:

The total sample space consists of 6 items

{79,64,84,82,92,77}

So,

n=6

The instructor has to randomly select 2 test scores out of 6.

So, r=6

The arrangement of scores selection doesn't matter so combinations will be used.

$C(n,r)=\frac{n!}{r!(n-r)!} \\C(6,2)=\frac{6!}{2!(6-2)!}\\=\frac{6!}{2!*4!}\\=\frac{6*5*4!}{2!*4!} \\=\frac{30}{2}\\=15\ ways$

Therefore, there are 15 different samples are possible without replacement ..

Elina [12.6K]

Answer:

Step-by-step explanation:

point-slope equation of the line: y+1 = -(x-3)

rearrange to solve for y:

y+1 = -x+3

y = -x + 2 slope-intercept form

Solve the equation x4 – 26x2 + 25 = 0 in the real number system.

gogolik [260]

Answer:

x = -1, 1, -5 , 5.

Step-by-step explanation:

x4 – 26x2 + 25 = 0

Factoring:

(x^2 - 25)(x^2 - 1) = 0

So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.

x^2 - 1 gives x^2 = 1 and x = +/- 1.
