Answer:

30

Step-by-step explanation:

Answer:

About -4.286

Step-by-step explanation:

First, let's set up the equation.

(24 + 6)/(3 - 2 [4 + 1])

Now, let us do the parenthesis first. (4 + 1). While we are at it, we can also do 24 + 6.

30/(3 - 2[5)]

Now, -2(5)

30/3 - 10

Let us do 3 - 10

30/-7

Lastly, 30/-7, which unfortunately, is a non-terminating decimal, which is about:

-4.286, rounded to the nearest thousandth.

Answer:

x= 4/16 stan

x=0.26 dec

Step-by-step explanation:

⬇ Hello! The answer would be down below! :) ⬇

x = 0 will be the answer.

Step-by-step explanation:

So, we start with [tex]\frac{3}{4} x = \frac{1}{5} x[/tex] .

For step 1 we should subtract [tex]\frac{1}{5} x[/tex]  on both sides.

[tex]\frac{3}{4} x - \frac{1}{5} x = \frac{1}{5} x - \frac{1}{5} x[/tex]

= [tex]\frac{11}{20} x = 0[/tex]

For step 2 we will multiply both sides by [tex]\frac{20}{11}[/tex].

[tex](\frac{20}{11})[/tex] x [tex](\frac{11}{20} x ) = (\frac{20}{11})[/tex] x [tex]\ (0)[/tex]

= x = 0

Answer:

E(X) = 1.9375

SD(X) = 1.20

Step-by-step explanation:

Let :

G = girl ; B = Boy

P(G) = 0.5 ; P(B) = 0.5

Sample space :

G, BG, BBG, BBBG, BBBBG, BBBBB

Using the multiplication rule of independence :

P(G) = 0.5

P(BG) = 0.5 * 0.5 = 0.25

P(BBG) = 0.5 * 0.5 * 0.5 = 0.125

P(BBBG) = 0.5 * 0.5 * 0.5 * 0.5 = 0.0625

P(BBBBG) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125

P(BBBBB) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125

Creating a probability distribution table :

X = 1, 2, 3, 4, 5

For X = 5 ;

P(BBBBG) + P(BBBBB) = 0.03125 + 0.03125 = 0.0625

X :___ 1 ____ 2 ____ 3 _____ 4 _____ 5

P(X) : 0.5 __ 0.25 _ 0.125 _0.0625 _0.0625

The expected value E(X) :

√(ΣX * P(X)) = (1*0.5)+(2*0.25)+(3*0.125)+(4*0.0625)+(5*0.0625) = 1.9375

The standard deviation SD(x) :

√(ΣX²*p(x) - E(X)²

√((1^2*0.5)+(2^2*0.25)+(3^2*0.125)+(4^2*0.0625)+(5^2*0.0625) - 1.9375^2)

√(5.1875 - 3.75390625)

√1.43359375

SD(X) = 1.197

SD(X) = 1.20

A line of best fit guides a line through a scatter plot of data points that best describes the association between those points.

A line of best fit guides a line through a scatter plot of data points that best describes the association between those points. Statisticians typically utilize the least squares approach to arrive at the geometric equation for the line, either through manual computations or regression analysis software.

A line of best fit can be approximately specified utilizing an eyeball the method by marking a straight line on a scatter plot so that the numeral of points above the line and below the line stands about equal (and the line passes via as many points as possible).

Answer:

1/6*1/2=1/12

Step-by-step explanation:

You basically multiply the probability of getting 1 which is 1/6 out of the total and the probability for getting heads is 1/2 because there are 2 outcomes heads or tails.

So then you multiply them to get the probability of both of them so thats why it is 1/12

Answer:

2/10

Step-by-step explanation:

We can get 2/10 by multiplying the probability of the spinner and the coin because the question wants the compound probablity.

Since there is 2 numbers less than 3 on the spinner and a 50 50 chance of getting tails, 2/5 * 1/2 is 2/10.

Answer:  82

Step-by-step explanation:

As we know remainder formula:-

 Dividend = Quotient × Divisor + Remainder

Here, dividend = Two digits number & divisor = Sum of digits

m + 10n = 8 × (m + n) + 2

 m + 10n = 8m + 8n + 2

 m - 8m + 10n - 8n = 2

 2n - 7m = 2

  2n = 7m + 2

 n = (7m + 2)/2 - -  (Eq.1)

Digits interchanged, two digits number is divided by sum of digits, quotient is 2 & remainder is 8.

Now, when digits interchanged:-

 Two digits number = 10m + n

Using same formula we get:-

 10m + n = 2 × (m + n) + 8

10m + n = 2m + 2n + 8

 10m - 2m + n - 2n = 8

 8m - n = 8

 8m = n + 8

 n = 8m - 8 - - - (Eq.2)

Comparing both equations:-

 (7m + 2)/2 = 8m - 8

 7m + 2 = 2(8m - 8)

 7m + 2 = 16m - 16

 7m - 16m = -16 - 2

 -9m = -18

 m = -18/-9

 m = 2

So, digit at unit's place = 2

Put this value in (Eq.2)

n = 8(2) - 8

n = 16 - 8

n = 8

So, digit at ten's place = 8

Now two digit number:-

 Two digit number = 2 + 10(8)

 Two digit number = 2 + 80

Two digit number = 82
