A 0.24 probability that one string is defective

Step-by-step explanation:

The sample probabiity:

P=\frac{6}{25}

P=0.24

If important to notice that this probability is from the sample, it can be extrapolated to the population but may not be the same.

Situation:
FromTheMoon [43]

Answer:

5.6 days

Step-by-step explanation:

We are given;

Initial Mass; N_o = 25 g

Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)

k = 0.1229

Formula is given as;

N_t = N_o•e^(-kt)

Plugging in the relevant values;

12.5 = 25 × e^(-0.1229t)

e^(-0.1229t) = 12.5/25

e^(-0.1229t) = 0.5

(-0.1229t) = In 0.5

-0.1229t = -0.6931

t = -0.6931/-0.1229

t = 5.6 days

Write an equation in slope intercept form for the line with slope -7 and y intercept 9
zysi [14]

Slope intercept form is y = ax + b, where a is equal to the slope value, and b is equal to the y-intercept.

You have both the slope and y-intercept, which means that all you need to do is plug in the numbers to the equation in order to get your answer!

Let's plug in -7 for a, which gives you y = -7x + b.

Next, we'll plug in the y-intercept, which gives you y = -7x + 9.

Hope this helps!! :)

Find C, the total of the payments, and the monthly payment. Choose the correct answers. 2yc Interest(n) = m(n+1)
vivado [14]

Answer:

"$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

Interest rate = 14 %

So, interest on $700 =

So, c = $98

Total payment = amount financed + c  = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

                                      =798 ÷ 12

                                      =$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!
