Based on the relation between two numbers considering their difference and multiple, the numbers are 50 and 250.

Let the one number be x. So, the other number, according to the information in question, will be 5x. Now representing the equation depending on the stated details -

5x - x = 200

Performing subtraction on Left Hand Side of the equation

4x = 200

Writing the equation again to find the value of x

x = 200/4

Performing division on Right Hand Side of the equation

x = 50

First number = 50

Another number = 50×5

Performing multiplication on Right Hand Side of the equation

Second number = 250

The two numbers according to multiple and difference are 50 and 250.

Answer:

it should equal 23

Step-by-step explanation:

to go from 10y to 5y, divide by 2. this also means you have to divide 46 by 2, which is 23.

\(5y=23\) is equivalent to \(10y=46\)

you could also solve for y in which \(y=4.6\) and plug that into 5y. that will also give you 23

Answer:

Step-by-step explanation:

f(n)= -3n + 2

to find :f(12)

substitute 12 in place of n

f(12)= -3*12 + 2

f(12)=-36 + 2

f(12)= -34

The value of the  f(12) is equal to -46 where the expression is

f(n) = -3n + 2.

Any mathematical statement which consist of numbers , variables and arithmetic operations is known as expression. An expression gives some numerical value when we put the value of variables in it.

Here, f(n)= -3n + 2 is the given expression.

So, we can find the value of f(12) by putting n=12 in f(n).

Put n=12 in f(n), we get

          f(12)= (-3)×12 + 2

                 = -48 + 2

                 = -46

Hence, the value of f(12) is -46.

The 95% confidence interval for the difference between the two population proportions is -0.022 < p₁ - p₂ < 0.222.

Given that,

In a survey, it was discovered that 68% of women and 78% of men preferred computer-assisted education to lectures, respectively. Each sample contained 100 people that were chosen at random.

We have to calculate the 95% confidence range for the difference between the two proportions.

We know that,

The 95% confidence interval for difference between two population proportions is given as follows :

\(((\bar p_{1} -\bar p_{2})\)±\(Z_{0.05/2}\sqrt{\frac{PQ}{n_{1} } +\frac{PQ}{n_{2} }} })\)

Here,

p₁ is 0.78

p₂ is 0.68

n₁ is 100

n₂ is 100

Z is 1.96

P is 0.73

Q is 0.27

So,

((0.78-0.68)±\(1.96\sqrt{\frac{(0.73)(0.27)}{100 } +\frac{(0.73)(0.27)}{100 }} })\)

(0.10±0.122)

(0.10-0.122,0.10+0.122)

(-0.022,0.222)

Therefore, The 95% confidence interval for the difference between the two population proportions is -0.022 < p₁ - p₂ < 0.222.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation of line P

\(2x+3y-5=0\implies 2x+3y=5\implies 3y=-2x+5 \\\\\\ y=\cfrac{-2x+5}{3}\implies y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{3}}x+\cfrac{5}{3}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\)

Answer:

x = 0 and y = -4

Step-by-step explanation:

2x + y = -4...................................(i)

-3y = 2x + 12................................(ii)

from (i)

2x+y=-4

=> y=-4-2x

again from (ii)

-3y=2x+12

=> -3(-4-2x)=2x+12

=> 12+6x=2x+12

=> 6x-2x=12-12

=> 4x=0

=> x= 0

now,

y=-4-2(0)

=> y=-4-0

=> y=-4
