Answer:

17) A(-1,1) B(-1,4) C(5,1)

18) (From origin moving rightwards)

A(0,0) B(a, 0) C(a,a) D(0,a)

Step-by-step explanation:

17) You just count the steps, how many steps left, right, up, or down

18) The first point is at the origin, so 0,0

The second point that lies on the x axis is (a,0) as it is a distance from the origin, 0 because it's on the x-axis.

The third point is (a,a) because it is a distance to the right of the origin AND a distance upwards from the x axis.

The fourth point (0,a) because it is on the vertical line (0) and is a distance above the origin.

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all

Art [367]

Nathan has an infection and he needs to be treated with penicillin
But there’s a 75% probability of him being allergic to penicillin
And to test if the skin reacts to penicillin, the test is 98% accuracy
So even if he has the allergy the test is only 98% accurate of identifying the allergy
Therefore we are asked to find the probability of both these events happening
Event 1 and event 2 both should happen then. When the ‘and’ function is used in probabilities then the probabilities of both events happening should be multiplied
Therefore probability that Nathan has the allergy and test predicts it is
= 75% x 98% = 0.735
The answer is D. 0.735

Ira Lisetskai [31]

Answer:

3 hours 8 seconds

Step-by-step explanation:

Juan and Andrés are older adults and marathoners. Today they participated in the international marathon of the Andes. The announcer who covers this sporting event reported that Juan had finished the race with a time of 3¾ hours. Tijuanito the route in ⅔ of hours more than Andrés, how long did Andrés finish the marathon ?.

It is given that,

Juan had finished the race with a time of 3¾ hours.

He takes ⅔ of hours more than Andrés.

We need to find how long did Andrés finish the marathon.

Time taken by Juan = $\dfrac{15}{4}$ hours

Time taken by Tijuanito is $\dfrac{2}{3}$ hours more than Andrés.

So, Andrés finish the marathon $\dfrac{15}{4}-\dfrac{2}{3}=3.08\ \text{hours}$ before.
