Solve the equation 4x^2-12x=7 algebraically for x.
ss7ja [257]
                            4x² - 12x = 7
                                      - 7  - 7
                       4x² - 12x - 7 = 0
                4x² + 2x - 14x - 7 = 0
2x(2x) + 2x(1) - 7(2x) - 7(1) = 0
          2x(2x + 1) - 7(2x + 1) = 0
                    (2x - 7)(2x + 1) = 0
       2x - 7 = 0    or    2x + 1 = 0
           + 7 + 7                 - 1  - 1
             2x = 7                 2x = -1
              2     2                  2      2
               x = 3¹/₂      or       x = ⁻¹/₂

15/4 in to equal mixed number
Temka [501]

9514 1404 393

Answer:

  3 3/4

Step-by-step explanation:

  \dfrac{15}{4}=\dfrac{12+3}{4}=\dfrac{12}{4}+\dfrac{3}{4}\\\\=3+\dfrac{3}{4}=\boxed{3\dfrac{3}{4}}

__

The integer part of the mixed number is the quotient when the numerator is divided by the denominator. The remainder from that division is the numerator of the fraction.

  15/4 = 15 ÷ 4 = 3 r 3 = 3 3/4

The 10 participants in an experiment had the following reaction times ( in milliseconds ) : 778,783,784,786,790,804,807,810,819,
Nata [24]

Answer:

Mean. It includes all data points.

Step-by-step explanation:

-We first need to calculate the mean, median and mode then compare our values:

#Mean:

\bar x=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{10}\sum{778+783+784+786+790+804+807+810+819+823}\\\\=\frac{1}{10}\times \\\\=798.40

#The median is the middlemost data point in a lsit data:

778,783,784,786,790,804,807,810,819,823

-Since our data points is an even number, the median number is calculated as:

median=\frac{1}2}\sum{5^{th}+6^{th}}\\\\=0.5[790+804]\\\\=797.00

#Mode is the data point with the highest frequency:

-Since there's no number appearing more than once, our set has no mode.

#Since our data set has no outliers and is not a skewed distribution, the mean will be the best measure as it includes all data points
