Traffic cameras showed that 15 of every 50 cars passing through a certain intersection did
not fully stop at the stop sign. Based on this sample, what is the probability that a car
arriving at this intersection will not fully stop?
0 0.03
0 0.15
0.30
0 0.50
Answers
Answer:
C, 0.30
Step-by-step explanation:
First, simplify.
[tex]\frac{15}{50}[/tex] = [tex]\frac{3}{10}[/tex]
Next, divide
3 ÷ 10 = 0.30 or 0.3
Have a great day!
Answer:
0.30 is the probability that a car arriving at this intersection will not fully stop.Step-by-step explanation:
Given that:
Total number of cars passing = 50 cars Number of cars not fully stop at the stop sign = 15 carsTo Find:
What is the probability that a car arriving at this intersection will not fully stop?We know that:
P(E) = F/TWhere,
P(E) = Probability of an event F = Favorable outcomes = 15T = Total outcomes = 50Finding the probability that a car arriving at this intersection will not fully stop:
⟶ P(E) = 15/50
Multiply by 2 with both numerator and denominator.
⟶ P(E) = (15 × 2)/(50 × 2)
⟶ P(E) = 30/100
⟶ P(E) = 0.30
Hence,
The probability that a car arriving at this intersection will not fully stop is 0.30.Related Questions

Answer:
133.7π cm^3 or approximately 418.77430072 cm^3.
Step-by-step explanation:
For the cylinder half, use the formula: π*r^2*h, or pi times radius squared times height.
Since the diameter is 8, which means the radius is 4, and the height is 6, the volume of the cylinder would be 96π or 301.59289474...
For the cone on top, use the formula 1/3 (π*r^2*h), or one third pi times radius squared times height. Don't forget to calcuate the part in parentheses before dividing it by three.
Because the overall height was 13, you can subtract the 6 from the cylinder to get the cone's height. It has a height of 7 and a radius of 4 just like the cylinder. The volume of the cone is 112π/3 or 37.3π.
Now add both volumes together to get 133.7π cm^3 or approximately 418.77430072 cm^3.
3 (a - 1) + 31 - 11a = 4 ( 2a + 3)
Answers
Answer:
-⅖
Step-by-step explanation:
We need to simplify the given equation and find out the value of a , as ,
=> 3(a-1)+31-11a = 4(2a+3)
=> 3a -3+31-11a = 8a + 12
=> -8a -28 = 8a + 12
=> 16a = -28-12
=> 16a = -40
=> a = -2/5
• Hence the value of a is -⅖ .3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )
____________________Solution :-Given Information :-Equation ➢ 3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )To Find :-The value of 'a'Calculation :-⇒ 3 ( a - 1 ) + 31 - 11a = 4 ( 2a + 3 )
Opening the brackets and multiplying the terms, We get,
⇒ 3a - 3 + 31 - 11a = 8a + 12
⇒ -8a + 28 = 8a + 12
⇒ 8a + 8a = - 28 - 12
⇒ 16a = 40
Transposing 16 to Right Hand Side, We get,
⇒ a = [tex] \sf \frac{40}{16} [/tex]
⇒ a = [tex] \sf \frac{-2}{5} [/tex]
____________________Final Answer :-The value of 'a' is [tex] \bf \frac{-2}{5} [/tex]____________________
The set of life spans of an appliance is normally distributed with a mean y = 48 months and a standard deviation or
8 months. What is the z-score of an appliance that stopped working at 64 months?
Answers
Answer:
The set of life spans of an appliance is normally distributed with a mean µ= 48 months and a standard deviation σ= 8 months. ... Thanh finds that his grade on the test has a z-score of -2.5. ... are normally distributed, and the probability that the city gets more than 43.2 inches of rain in a year is given by P(z≥1.5)=0.0668.
Step-by-step explanation:
=============================================================
Explanation:
The raw score is x = 64, and we want to find its corresponding z score.
The mean and standard deviation are mu = 48 and sigma = 8 respectively.
The z score is...
z = (x-mu)/sigma
z = (64-48)/8
z = 16/8
z = 2
A z score of 2 means we're 2 standard deviations above the mean.
As the formula above implies, we find the difference from the raw score (x) to the mean (mu). Then we divide over sigma to find out how many sigma steps we have to take to go from mu to x.
A negative z score would indicate the raw score is below the mean.
Sara has 3 1/2 feet of ribbon.
She needs 2/3 foot to make one bow.
How many bows can she make?
Answers
Answer:
5 bows
Step-by-step explanation:
Total feets of ribbon = 3 1/2
Fraction required to make a bow = 2/3
Number of bows that can be made = (total ribbon / Fraction required to make a bow)
3 1/2 ÷ 2/3

AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm

TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π
