Answer:

\dfrac{15}{19}

Step-by-step explanation:

The soccer player so far has made 15 penalty kicks in 19 attempts.

Therefore:

Total Number of trials =19

Number of Successes =15

Therefore, the relative frequency probability that she will make her next penalty​ kick is:

=\dfrac{\text{Number of Successes}}{\text{Total Number of Trials}} \\=\dfrac{15}{19}

Solve the following quadratic equation for all values of x in simplest form. 4(3x - 5)/1+5 = 13
Inga [223]

<u>To</u><u> </u><u>find</u><u> </u><u>:</u>

  • The value of x.

<u>S</u><u>o</u><u>l</u><u>v</u><u>i</u><u>n</u><u>g</u><u> </u><u>the</u><u> </u><u>equation</u><u> </u><u>:</u>

\longmapsto \sf { \dfrac{4(3x-5)}{1+5} = 13}

\longmapsto \sf { \dfrac{12x-20}{6} = 13}

\longmapsto 12x - 20 = 6 × 13

\longmapsto 12x - 20 = 78

\longmapsto 12x = 78 + 20

\longmapsto 12x = 98

\longmapsto x =\sf { \dfrac{98}{12} }

  • Divide the numerator and the denominator in R.H.S by 2.

\longmapsto \bf\red { x = \dfrac{49}{6} }

Value of x is 49/6.
