The expression is given by:

-\frac{1}{4}x+ \frac{1}{2}

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

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

Or extracting the common factor -1/4, then:

-\frac{1}{4}(x-2})

So, comparing these solutions with the answers about, there is no any answer that matches.

The given expression is:

- \frac{1}{4}x+  \frac{1}{2}

1/2 can be written as 2 x 1/4 . So the expression becomes:

- \frac{1}{4}x+ \frac{1}{4}*2

Taking out 1/4 as common we get:

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

Calculate the data value that corresponds to each of the following z-scores.
Fynjy0 [20]

Answer:

a) 90.1

b) $35.6

c) 3.0915 hours

Step-by-step explanation:

The z-score measures how many standard deviations a score X is above or below the mean.

It is given by the following formula:

Z = \frac{X - \mu}{\sigma}

In which \mu is the mean and \sigma is the standard deviaition.

In all three cases, we have to find X

a. Final exam scores: Allison’s z-score = 2.30, μ = 74, σ = 7.

Z = \frac{X - \mu}{\sigma}

2.30 = \frac{X - 74}{7}

X - 74 = 7*2.3

X = 90.1

b. Weekly grocery bill: James’ z-score = –1.45, μ = $53, σ = $12.

Z = \frac{X - \mu}{\sigma}

-1.45 = \frac{X - 53}{12}

X - 53 = -1.45*12

X = 35.6

Mean and standard deviation in dollars, so the answer also in dollars.

c. Daily video game play time: Eric’s z-score = –0.79, μ = 4.00 hours, σ = 1.15 hours.

Z = \frac{X - \mu}{\sigma}

-0.79 = \frac{X - 4}{1.15}

X - 4 = -0.79*1.15

X = 3.0915

Mean and standard deviation in hours, answer in hours.

the first few steps in solving the quadratic equation 5x2 27x = 14 − 13x by completing the square are shown. 5x2 27x = 14 − 13x
Artist 52 [7]
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since  80 =  5 · 16
5 ( x² + 8 x + 16 ) = 94   Answer : B ) 
After that we will continue like this:
5 ( x + 4 )² = 94 
( x + 4 )² = 18.8 ... etc
