1 answer:

8 0

In either game, 50 tosses would increase your chances of winning.

The theoretical probability of flipping heads is 1/2 or 50%. The more times you perform an experiment, the closer the experimental probability is to the theoretical. This means that your average will be closer to 50% the more times you perform the experiment.

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

nevsk [136]

Step-by-step explanation:

Points are (8,5) and (-12,-9)

The equation of a line passing through two points is given by :

$y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56$

$-50+56=7x-10y\\\\7x-10y=6$

But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.

Luis made 80% of what he made last week.If he made 72$ this week,how much did he make last week

IceJOKER [234]

Let

x--------> the amount in dollars that Luis make last week

we know that

$80\% =\frac{80}{100}=0.80$

$0.80x=72\$$ ------> equation that represent the situation

solve for x

Divide by $0.80$ both sides

$0.80x/0.80=72\$/0.80$

$x=72\$/0.80$

$x=90\$$

therefore

<u>the answer is</u>

$90\$$

Joanne has a goal of buying a townhome and saved for 5 years. She expected to have the down payment of $15,000 saved by now but

serg [7]

Answer:

Step-by-step explanation:

Average amount saved per year = $\frac{15,000}{5}$

=$ $3000$

So on average Joanne has saved $3000 per year. She only needs $2000 more which will not even take a year to save.

How many months it will take to save $2000:

$\frac{12}{3000} \times2000$

= $8$ Months.

It will only take Joanne 8 moths to save $2000.

If she really wants to buy the home now she can always go for a home loan scheme for $2000. Any interest rate less than 50% per year is fine as she can save $3000 per year.
