Step-by-step explanation:

=  \frac{1}{2}  +  ( - 5 \frac{9}{10} )

=  \frac{1}{2}  - 5 \frac{9}{10}  \\

=  \frac{1}{2}  -  \frac{5 \times 10 + 9}{10}  \\

=  \frac{1}{2}  -  \frac{59}{10}  \\

=  \frac{1}{2}  \times  \frac{5}{5}  -  \frac{59}{10}  \\

=   \frac{5}{10}   -  \frac{59}{10}  \\

=  \frac{5 - 59}{10}  \\

=  -  \frac{54}{10}  \\

=  -  \frac{27}{5}  \\

Answer:

-5 \frac{2}{5}

Step-by-step explanation:

\frac{1}{2} +\left( -5\frac{9}{10} \right)

= \frac{1}{2} -\left( 5\frac{9}{10} \right) \ \ \ \text{(recall\ :\ + - = - )}

= \frac{1}{2} -\left( 5+\frac{9}{10} \right)

= \frac{1}{2} -5 - \frac{9}{10} \right)

= \frac{5}{10} -5 - \frac{9}{10} \right)

=  -5 + \frac{5}{10} - \frac{9}{10} \right)

=  -5 - \frac{4}{10}

=  -5 - \frac{2}{5}

=  -5 \frac{2}{5}

Given the function k(t) = 6t − 9,<br> complete the following Solve k(t) = 21.
ELEN [110]

Answer: 5(k)

Step-by-step explanation: “k”times “t” equals 6t-9 so if “k” times “t” equals 21, 6t-9=21, add 9 to 21 which equals 30 so then you divide 30 by 6 to get 5. “t”=5 which means the solution is 5(k)

With a little care, you can find the median and the quartiles from the histogram. what are these numbers? you can also find the
coldgirl [10]

Complete Question

The histogram from this question is shown on the first uploaded image

Answer:

The first quartile is  1st Q = 19^{th} girl (subject ) = 1 \serving\ of\ fruit\ per\ day

The median is   Median  = 38 ^{th} \ girl (subject) =  2 \serving\ of\ fruit\ per\ day

The third quartile  is 3rd Q =  56^{th} \  girl (subject) = 4 \serving\ of\ fruit\ per\ day  

The  mean is  \= x = 2.62

Step-by-step explanation:

From the question we are told that

   The total  number of girls is n =  74

Generally the median is mathematically represented as

       Median  =  \frac{\frac{n}{2}  +[ \frac{n}{2} + 1]  }{2}

So

          Median  =  \frac{\frac{74}{2}  +[ \frac{74}{2} + 1]  }{2}

=>         Median  =  \frac{37  +38 }{2}

=>         Median  =37.5 \  girl    

From the histogram 37.5 \approx 38^{th} \ girl fall under 2 fruits per day

Generally the first quartile is mathematically represented as

      1st \ Q =  \frac{\frac{n}{4} + [\frac{n}{4} + 1]  }{2}

=>    1st \ Q =  \frac{\frac{74}{4} + [\frac{74}{4} + 1]  }{2}

=>     1st \ Q = 19 \  girl

From the histogram 19^{th}girl fall under 1 fruit per day

 Generally the third quartile is mathematically represented as

     3rd\  Q =  \frac{\frac{n}{2}  + n }{2}

=>    3rd\  Q =  \frac{\frac{74}{2}  + 74 }{2}

=>    3rd\  Q =  55.5

From the histogram 55.5 \approx 56^{th} \ girl fall under 4 fruits per day

Generally from the histogram table the frequency  [number of subjects (girls) ]  and the servings of fruit per day can be represented as

                                                                                                               Total

x(servings per day )        0     1     2     3     4     5    6     7      8    

f (number of subjects )   15    11   15     11    8     5    3     3      3    \sum f  =  74

xf                                       0    11    30   33   32  25   18   21     24    \sum xf =  194

Generally the mean is mathematically represented as

      \= x = \frac{1}{ \sum f}  * [\sum xf]

=>     \= x = \frac{1}{ 74}  *194

=>      \= x = 2.62

PLEASE HELP!
fenix001 [56]

Answer:

No

Step-by-step explanation:

No because (1,2) falls on the line, and the line is a dotted line, which means that any point on the line is not a solution to the inequality.
