What is the first ordered pair and the second ordered pair?

Mathematics
1 answer:
Delvig [45]3 years ago
7 0
When x=-5, y=(1/5)*(-5)-1=-2, so the first order pair is (-5,-2)
when y=-1, -1=(1/5)x-1, (1/5)x=0, x=0, so the second ordered pair is (0, -1)

Solve for x. Round your answer to the nearest tenth (0.1)
Marizza181 [45]

Answer:

x\approx 7.0

Step-by-step explanation:

Since we are given a right triangle, we can use right trigonometric ratios.

<em>x</em> is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:

\displaystyle \tan(\theta^\circ)=\frac{\text{opposite}}{\text{adjacent}}

Substitute:

\displaystyle \tan(35^\circ)=\frac{x}{10}

Solve for <em>x:</em>

<em />x=10\tan(35^\circ)<em />

Use a calculator:

x=7.0020...\approx 7.0

1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green
dimulka [17.4K]

Answer:

Dependent Event

Step-by-step explanation:

Assume that are 10 balls, such that:

Red = 6

Green = 4

If the balls are replaced after taken, the probability is:

Pr(Red) = 6/10

Pr(Green) = 4/10

This is referred to as independent event; because each selection do not affect the next or previous selection

However, if the balls are not replaced, the probability is:

Pr(Red) = 6/10

Pr(Green) = 5/(10 - 1) = 5/9

We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.

This is referred to as independent event; because a selection affects the next selection

Write the statement in if-then form in two ways, one of which is the contrapositive of the other: Sam will be allowed on Signe's
bezimeni [28]

Answer:

1) If Sam is an expert sailor then she will be allowed on Signe's racing boat.

2) If Sam is not allowed on Signe's racing boat, then she is not an expert sailor.

Step-by-step explanation:

  • The contrapositive statement of if P → Q is if ~Q→~P.

In this case we have: If Sam is an expert sailor then she will be allowed on Signe's racing boat.

P = Sam is an expert sailor

Q = Sam will be allowed on Signe's racing boat.

To write the contrapositive statement we're going to say if ~Q→ ~P

If Sam is not allowed on Signe's racing boat, then she is not an expert sailor.
