Answer: Y=-3/4x-2

Step-by-step explanation:

you fill in the blank because It’s y=Mx+b and m=slope b=y intercept so y=-3/4x-2

What is the median for the following set of numbers? 10, 13, 15, 12, 9, 12, 16

Pani-rosa [81]

Answer:

Step-by-step explanation:

Arranging in ascending order -> 9, 10, 12, 12, 13, 15, 16

n = 7

Median = value of ((n + 1) / 2) th term

= value of (7+1) / 2 th term

= value of 4 th term

= 12

Hope it helps :)

Find the cost of lodging: A resort offers a double room for $87.00. Meals in the restaurant are $9.00 per person for breakfast,

zubka84 [21]

Answer:

Step-by-step explanation:

Hotel room = 87.00 a double room means for two people

breakfast = 9.00 X 2 = 18.00

Lunch 14.00 X 2 = 28.00

Dinner 16.00 X 2 = 32.00

add the amounts all together 87 + 18 + 28+ 32 =$165.00 for 2 people

Question 37 (1 point)

o-na [289]

Answer:

The probability is:

$P =\frac{1}{16}$

Step-by-step explanation:

Keep in mind that the probability of getting a head is always the same for each

$p = 0.5$

Therefore the probability of not having a head is:

$q = 1-p = 0.5\\q = 0.5$

So if we throw the coin 4 times the probability P of not getting any head is:

$P = q * q * q * q\\\\P = q ^ 4\\\\P = 0.5 ^ 4\\\\$

$P =\frac{1}{16}$

A bacteria culture starts with 660 bacteria and grows at a rate proportional to its size. After 6 hours there will be 3960 bacte

scoray [572]

Answer:

a) $P(t) = 660 e^{\frac{ln(6)}{6} t}$

b) $P(t=3) = 660 e^{\frac{ln(6)}{6}*3} = 1616.663 \approx 1617$

Step-by-step explanation:

For this case we have the following info:

$P(0) = 660$ represent the initial amount of bacteria

$P(6) = 3960$ represent the population of bacteria after 6 hours

Part a

For this case we use the proportional model given by:

$\frac{dP}{dt}= kP$

Where P represent the population at time t and k is a constant of proportionality.

We can rewrite the model like this:

$\frac{dP}{P} = k dt$

And if we integrate both sides we got:

$ln |P|= kt + C$

Now if we apply exponential we got:

$P = e^{kt +c}= e^{kt} e^C$

$P(t)= P_o e^{kt}$

For this case using the initial condition:

$660 = P_o e^{0k}, P_o = 660$

We have the following model:

$P(t) = 660 e^{kt}$

Using the second condition $P(6) = 3960$ we have this:

$3960 = 660e^{6k}$

We can divide both sides by 660 and we got:

$6= e^{6k}$

Now we can apply natural log on both sides and we got:

$ln (6)= 6k$

$k = \frac{ln(6)}{6}=0.2986265782$

So then the model would be given by:

$P(t) = 660 e^{\frac{ln(6)}{6} t}$

Part b

For this case we just need to replace t=3 into the model and we got:

$P(t=3) = 660 e^{\frac{ln(6)}{6}*3} = 1616.663 \approx 1617$
