\frac{1}{2} (x+12)=4x-1

Multiply  both sides by 2 :

\frac{1}{2}(x+12)*2 = 4x*2-1*2

x+12=8x-2

x+12-12=8x-2-12

x=8x-14

Subtract 8 x from both sides:

x-8x=8x-14-8x

-7x=-14

Divide both sides by -7 :

\frac{-7x}{-7} = \frac{-14}{7}

x = \frac{14}{7}

x = 2

PLEASE HELP!!!! Emily is making 2 gallons of punch with 4 parts grape juice to 3 parts pineapple juice to 1 part sparkling cider
True [87]

1 gallon = 16 cups. She is making 2 gallons so needs 32 total cups.

The ratio is 4:3:1

Add the ratios: 4+ 3 + 1 = 8

Divide total cups by total ratio:

32/8 =4

Now multiply that by each portion of the ratio:

Grape juice = 4 x 4 = 16 cups

Pineapple juice = 3x4 = 12 cups

Cider = 1x 4 = 4 cups

She needs 12 cups of pineapple juice.

How would you write 2x^2-7=11 in both quadratic property and square root property?
dangina [55]

Answer:

Quadratic Property 2x^2-18=0

Square Root Property x=√9 or x=+3 or x=-3

Step-by-step explanation:

Quadratic Property or a quadratic Function is of the form ax^2+bx+c=0. So our task is to equate the given expression to zero. We can equate the expression to zero by subtracting 11 on both the sides. In doing so, we get 2x^2-18=0. This is the quadratic Property of the given Expression.

Square property is finding the value for x. we have make x equal to some value. Since we already have the quadratic Property as 2x^2-18=0, we can use this to find the value of x.

so, 2x^2=18

or x^2=18/2=9

or x=√9= +3 or -3.

A sample of 56 research cotton samples resulted in a sample average percentage elongation of 8.63 and a sample standard deviatio
ss7ja [257]

To solve for the confidence interval for the true average percentage elongation, we use the z statistic. The formula for confidence interval is given as:

Confidence interval = x ± z σ / sqrt (n)

where,

x = the sample mean = 8.63

σ = sample standard deviation = 0.79

n = number of samples = 56

 

From the standard distribution tables, the value of z at 95% confidence interval is:

z = 1.96

 

Therefore substituting the known values into the equation:

Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)

Confidence interval = 8.63 ± 0.207

Confidence interval = 8.42, 8.84
