find the value of x

Answers

Answer:

x = 5

Step-by-step explanation:

(10/3)/5 = (x+1)/9

(10/3)9 = 5(x+1)

90/3 = 5x + 5

30 = 5x + 5

25 = 5x

x = 5

5. 10/3
9. X+1

5(x+1)=9•10/3
5x+5=9/1•10/3
5x+5=30
5x=30-5
5x=25
X=25/5
X=5

Sean earns $ 6.70 per hour working after school. He needs at least $155(greater than or equal to 155) for a stereo system. Write an inequality that describes how many hours he must to reach his goal.)

Answers

6.70h >_ 155
(>_ represents greater than or equal)

Answer:

6.70h <= 155

Step-by-step explanation:

1. Define a variable.

Let h = number of hours

2. Write the inequality.

We know that he earns $6.70 an hour. We also know that he needs at least $155, which means he needs greater than or equal to 155. Therefore, 6.70h <= 155.

Answer:

  ∠2 = 19°

Step-by-step explanation:

Angles that are equal to 161° are vertical and corresponding angles: 1, 4, 5.

Angles that are equal to the supplement of 161° are the remaining angles: 2, 3, 6, 7.

Angle 2 is the supplement of 161°:

for substitution: -2x -2y = 10 y = 4x - 20
6x + 8y = -22 y = -5 (for both plug in the second equation as y in the first equation if that makes sense) (first answer is (3, -8); second answer is (3, -5)

for elimination: 3x + 4y = 2.5 5x - 4y = 25.5 (adding will get you to 8x = 28 bc it gives you 0y; answer is (7/2, -2))
3x + 4y = 2.84 3x - y = 1.79 (gives you 3y = 1.05 if you subtract; answer is (0.48, 0.35))

Traffic on Rosedale Road in Princeton, NJ, follows a Poisson process with rate6cars per minute. Adeer runs out of the woods and tries to cross the road. It takes the deer a random time (independentof everything else), uniformly distributed between2and5seconds, to cross the road. If there is acar passing while the deer is on the road, it will hit the deer with portability2/3(independent ofeverything else). Find the probability of a collision.

Answers

Answer:

Step-by-step explanation:

From the given information:

6 cars pass on the road per minute. This implies that per minute, we will have:

6/60 passes = 0.1 car passing the road per second

Thus, for 5 sec; we have:

5 × 0.1 = 0.5

Let assume X signifies to be a random variable which denote the no of cars in the next  5 minutes and which follows a Poisson distribution.

i.e.

[tex]X \sim Poisson (0.5)[/tex]

[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 5 seconds)} \\ \\ =1 - P(X=0)[/tex]

[tex]= 1- \dfrac{[e^{-0.5\times 0.5^0}]}{0!}[/tex]

[tex]= 1 - e^{-0.5}[/tex]

[tex]= 1 - 0.6065[/tex]

[tex]= 0.3935[/tex]

However, the possibility of collision supposes the deer requires 2 seconds to cross the road can be computed as follows:

Suppose Y denote the arbitrary variable that addresses the no. of cars passing the road in 2 secs, then;

[tex]Y \sim Poisson (0.2)[/tex]

[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 2 seconds)} \\ \\ =1 - P(Y=0)[/tex]

[tex]= 1- \dfrac{[e^{-0.2\times 0.2^0}]}{0!}[/tex]

[tex]= 1 - e^{-0.2}[/tex]

[tex]= 1 - 0.8187[/tex]

[tex]= 0.1813[/tex]

10. Solve for z: 2 + 8 - z = -24

Answers

Answer:

The answer is z = 34.

Step-by-step explanation:

1) Simplify 2 + 8 - z to 10 - z.

[tex]10 - z = - 24[/tex]

2) Subtract 10 from both sides.

[tex] - z = - 24 - 10[/tex]

3) Simplify - 24 - 10 to -34.

[tex] - z = - 34[/tex]

4) Multiply both sides by -1.

[tex]z = 34[/tex]

Therefor, the answer is z = 34.
