(a/bc) - d = x is the answer

Answer:

The value of the equation for x is x=\frac{a-d}{b+c}.

Step-by-step explanation:

Consider the provided equation.

a=bx+cx+d

We need to solve the equation for x.

Subtract d from both sides.

a-d=bx+cx+d-d

a-d=bx+cx

Take x common from right side.

a-d=x(b+c)

Divide both the sides by b+c.

\frac{a-d}{b+c}=\frac{x(b+c)}{b+c}

x=\frac{a-d}{b+c}

Hence, the value of the equation for x is x=\frac{a-d}{b+c}.

A new roll of wrapping paper has 6 5/8 yards of paper. Drew used 2 1/6 yards from the roll to wrap a gift. Which equation most c
Sedbober [7]
First you have to make both fractions have the same denominator, so you can multiply each fraction by the others denominator.

5/8
To
(5*6)/(8*6)

And

1/6
To
(1*8)/(6*8)

Now it's 6 30/48 - 2 8/48

= 4 22/48

Now reduce to

= 4 11/24

So, 4 11/24 is the answer

National statistics show that 23% of men smoke and 18.5% of women smoke. A random sample of 175 men indicated that 45 were smoke
NeTakaya

Answer:

98% C.I. = [-0.1270, 0.0994]

Step-by-step explanation:

Here

p1= proportion of men smokers

p1= 45/175= 0.2571

p2= proportion of women smokers

p2= 42/155= 0.2709

1)  Choose the significance level ∝= 0.02

2) The formula for confidence interval is

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

and

(p1^- p2^) z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

<u>3)  The z value is 2.05</u>

<u>4) Calculations:</u>

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(-2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=-0.1270 ( using calculator)

And

(p1^- p2^)z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=0.0994  ( using calculator)

and Putting ± 2.05 in the confidence interval formula we get limits (-0.1270, 0.0994)
