Answer:

you would first put a point at (15, -50) then go down 3 places then go down 1 place,

Step-by-step explanation: when a slop is just a number, always put a 1 under it

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.

disa [49]

This is a Bayes Theorem Problem

P(oil | negative test) P(negative test)= P(negative test | oil) P(oil)

P(oil | negative test) = P(negative test | oil) P(oil) / P(negative test)

P(oil | negative test) =P(negative test | oil) P(oil) / ( P(negative test | oil) P(oil) + P(negative test | no oil) P(no oil) )

We're given the prior probability of oil, P(oil)=.45, so P(no oil)=.55

We given P(negative test | no oil) = 0.80, so P(negative test | oil) = .20

$P(\textrm{oil} | \textrm{negative test}) = \dfrac{ .20(.45) }{.20(.45) + .80(.55)} = 0.1698$

lions [1.4K]

Suppose $y_p=a_0+a_1t$ is a solution to the ODE. Then ${y_p}'=a_1$ and ${y_p}''=0$ , and substituting these into the ODE gives

$a_1-4(a_0+a_1t)=7t+5\implies\begin{cases}-4a_1=7\\-4a_0+a_1=5\end{cases}\implies a_0=-\dfrac{27}{16},a_1=-\dfrac74$

Then the particular solution to the ODE is

$y_p=-\dfrac{27}{16}-\dfrac74t$

Juanita and Keenan own a camping supply store and just put in an order for flashlights and sleeping bags. The number of flashlig

julsineya [31]

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.

Step-by-step explanation:

Given,

Cost of each flashlight = $12

Cost of each sleeping bag = $45

Total cost = $1785

Let,

x represent the number of flashlights ordered

y represent the number of sleeping bags ordered

According to given statement;

12x+45y=1785 Eqn 1

x = 5y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$12(5y)+45y=1785\\60y+45y=1785\\105y=1785\\$

Dividing both sides by 105

$\frac{105y}{105}=\frac{1785}{105}\\y=17$

Putting y=17 in Eqn 1

$x=5(17)\\x=85$

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.
