Gary spends 10 per week on the internet and 13 hours per week playing video games. If Gary has five hours of free time per day w
Natalka [10]

Answer:

460% of free time is spent on internet and games .

Step-by-step explanation:

Given as :

The time spent by Gary on internet = 10 hours per week

The time spent by Gary on video games = 13 hours per week

So, Total time spent by Gary = 10 hours per week + 13 hours per week

                                                = 23 hours per week

The free time which Gary have = 5 hours

Now, percentage of free time spent on internet and games = x %

So, x % of 5 = 23

or, x % = \frac{23}{5}

∴  x% = 4.6

I.e x = 460 %

Hence  460% of free time is spent on internet and games . Answer

Answer:

1) The value of c is given by

c=4

2) The value of k is given by

k=-4150

Step-by-step explanation:

Given that function g is defined by g(x)=cx-3 , where c is a constant.

To find c:

Also given that value of g(x) at x=0.5 is equal to -1

ie., g(0.5)=-1

At x=0.5

g(0.5)=c(0.5)-3=-1

(0.5)c-3=-1

(0.5)c=-1+3

(0.5)c=2

c=\frac{2}{0.5}

c=\frac{2}{\tfrac{1}{2}}=2\times \frac{2}{1}

Therefore c=4

2) Given that function h is defined by h(x)=\frac{20x-k}{x+50} , where k is a constant.

To find k:

Also given that value of h(x) at x=20 is equal to 65

ie., h(20)=65

At x=20

h(20)=\frac{20(20)-k}{20+50}=65

400-k=65(70)

-k=4550-400

-k=4150

Therefore k=-4150

A number t decreased by 2 is at least 7
9966 [12]
Answer:
t - 2 ≥ 7; t ≥ 9

Explanation:
“a number t” = t
“decreased by 2” = - 2
“Is at least 7” = ≥ 7
So, t - 2 ≥ 7

To solve for t - 2 ≥ 7, add 2 to both sides of the equation

t - 2 ≥ 7
t - 2 + 2 ≥ 7 + 2
t ≥ 9

So, t ≥ 9

Hatshy [7]

<u>0.0931</u><u>  is the </u><u>probability </u><u>that at least 10 pay in cash.</u>

What is a probability simple definition?

The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Using binomial distribution with n= 15, and p = 0.40,

P(8<X<12) = P(X=9)+P(X=10) + P(X=11)

                 = 0.0612+0.0245+0.0074

                  = 0.0931

Therefore,0.0931  is the probability that at least 10 pay in cash.
