Rona was driving on an asphalt road that had a 35 mile per hour speed limit posted. A lrr r deer jumped out from the side of the road causing Rona to slam on her brakes. Her tires left three skid marks of lengths 70 ft., 72ft., and71ft. The road had a drag factor of .78. Her brakes were operating at 95% efficiency. The police gave Rona a ticket for speeding. Rona insisted that she was driving under the speed limit. Who was correct (the police or Rona)

Answers

Answer 1

Answer:

The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."

Step-by-step explanation:

Finding the average skid distance:

[tex]Average=\frac{70+71+72}{3}=\frac{213}{3}=71[/tex]

Calculating the skid:  

[tex]S=\sqrt{30 \times D \times f\times n}\\\\[/tex]  

   [tex]=\sqrt{30 \times 71 \times 0.78\times 0.95}\\\\=\sqrt{1,578.33}\\\\=39.73[/tex]

Ten cards numbered 1 through 10 are mixed together and then one card is drawn. Find the probability of each event. Write each answer as a fraction, percent, and decimal. P(less than 5) P(greater than 3) P(odd) P(even) P(not a multiple of 4) P(not 5, 6, 7, or 8) P(divisible by 3)

Answers

Answer:

2/5, 0.4, 40%

7/10, 0.7, 70%

1/2, 0.5, 50%

1/2, 0.5, 50%

4/5, 0.8, 80%

3/5, 0.6, 60%

3/10, 0.3 ; 30%

Step-by-step explanation:

Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

P(less Than 5) :

Required = (1, 2, 3, 4) = 4 observations

P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%

Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations

P greater Than 3) = 7/10 = 0.7 = 70%

Odd = (1,3,5,7,9) = 5

P(odd) = 5 / 10 = 1/2 = 0.5 = 50%

(even) = (2,4,6,8,10) = 5

P(even) = 5 / 10 = 1/2 = 0.5 = 50%

Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8

P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%

not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6

P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%

Divisible by 3 = (3, 6, 9) = 3

P(divisible by 3). = 3/10 = 0.3 = 30%

Find the value of R and S

Answers

Answer:

R ≈ 17.7

S ≈ 19.0

Step-by-step explanation:

The angles of the triangle are 90, 43, and 47. Given these we can apply the law of sines.

26/sin(90) = s/sin(43), giving you 17.73195, rounding to 17.7.

26/sin90 = r/sin(47), giving you 19.01519, rounding to 19.0.

Each bag of pears weighs 1 kg 160 gram. What is total weight of a sack which contains 5 bags of pears?

Answers

Answer:

5 kg 800 grams

5800g

Step-by-step explanation:

the first step is to convert 1kg to gram

100 kilogram = 1 gram

1kg x 1000 = 1000g

1kg 160 gram = 1000 + 160 = 1160 gram

If 1 sack weighs 1160 g

5 sacks = 1160g x 5 = 5800 gram

or 5800 / 1000 = 5 kg 800 grams

black horizontal line : y = 0

black vertical line : x = 0

Step-by-step explanation:

it is really simple.

blue line : no matter what value we pick for x, the functional value for y is always 3. and that defines the equation y = 3 + 0*x or simply y = 3.

the same with the black horizontal line. the difference is that y is now always 0. so, y = 0.

What is a Geometric Series?

A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.

The standard equation for geometric series is

Tₙ = a₁ rⁿ⁻¹

The sum of an infinite geometric series is given by

S = a₁/(1-r)

where a₁ is the first term and r is the common ratio.
