Which shows the decimal 1.7 expressed as a fraction in simplest form?

-79 = 7w + 3(4w – 1)

vladimir1956 [14]

Hello! The answer to your question would be as followed:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-79-(7*w+3*(4*w-1)=0

-79 - (7w + 3 • (4w - 1)) = 0

Pulling out like terms :

Pull out like factors :

-19w - 76 = -19 • (w + 4)

-19 • (w + 4) = 0

Equations which are never true :

Solve : -19 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

Solve : w+4 = 0

Subtract 4 from both sides of the equation :

w = -4

If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .

Because of variability in the manufacturing process, the actual yielding point of a sample of mild steel subjected to increasing

Elena-2011 [213]

Because of variability in the manufacturing process, the actual yielding point of a sample of mild steel subjected to increasing stress will usually differ from the theoretical yielding point. Let p denote the true proportion of samples that yield before their theoretical yielding point. If on the basis of a sample it can be concluded that more than 20% of all specimens yield before the theoretical point, the production process will have to be modified. A button hyperlinks to the SALT program that reads: Use SALT. (a) If 12 of 48 specimens yield before the theoretical point, 0.3463 is the P-value when the appropriate test is used.

Because the P-value is rather large, He would not be rejected at any reasonable, so the production process will have to be modified.

Variability, almost by definition, is the extent to which data points in a statistical distribution or data set deviate (change) from the mean, and the extent to which those data points differ from each other.
