A researcher tests the braking distances of several cars. The braking distance from 60 miles per hour to a complete stop on dry pavement is measured in feet. The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet. What is the longest braking distance one of these cars could have and still be in the bottom 1%
Answers
Answer:
The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet.
This means that [tex]\mu = 129, \sigma = 5.18[/tex]
What is the longest braking distance one of these cars could have and still be in the bottom 1%?
This is the 1st percentile, which is X when Z has a pvalue of 0.01, so X when Z = -2.327.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-2.327 = \frac{X - 129}{5.18}[/tex]
[tex]X - 129 = -2.327*5.18[/tex]
[tex]X = 116.94[/tex]
The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.

Answers
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters

how do you solve the inequality of -11.3 is equal to or greater than -4.7 + 4x
Answers
Answer: -1.65 ≥ x
Step-by-step explanation:
We usually express "equal to or greater than" by using the symbol ≥.
And we set up the inequality by looking at the word description, then we have:
-11.3 ≥ -4.7 + 4x plus 4.7 on both sides.
-6.6 ≥ 4x divide 4 on both sides.
-1.65 ≥ x

have at the end of the five-year period?
Answers
Answer:
$13,756.31
Step-by-step explanation:
The computation of the amount at the end of the five years is shown below:
Here we applied the FV formula
Given that
NPER = 5 × 52 = 260
RATE = 2.25% ÷ 52 = 0.043269%
PV = $0
PMT = $50
The formula is given below:
=-FV(RATE;NPER;PMT;PV;TYPE)
After applying the above formula, the future value is $13,756.31

Answer: 32.14 after round off it will be 32
Step-by-step explanation:
This is how to round 32.14 to the nearest whole number. In other words, this is how to round 32.14 to the nearest integer.
32.14 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 32
Fractional Part: 14
Our goal is to round it so we only have an integer part using the following rules:
If the first digit in the fractional part of 32.14 is less than 5 then we simply remove the fractional part to get the answer.
If the first digit in the fractional part of 32.14 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.
The first digit in the fractional part is 1 and 1 is less than 5. Therefore, we simply remove the fractional part to get 32.14 rounded to the nearest whole number as:

Answers
9514 1404 393
Answer:
10. $16,000
11. 4%
12. 16.9%
Step-by-step explanation:
10. The amount of the loan plus interest is given by the formula ...
I = Prt
P = I/(rt) = $7840/(0.07×7) = $16,000
Richard initially deposited $16,000.
__
11. The total of principal plus interest is ...
A = P(1 +rt)
Solving for r gives ...
r = (A -P)/(Pt) = (528000 -240000)/(240000×30) = 0.04 = 4%
The percentage rate used was 4%.
__
12. The interest formula is ...
I = Prt
Solving for r gives ...
r = I/(Pt) = $845/($1000×5) . . . . . . 60 months = 5 years
r = 0.169 = 16.9%
To earn $845 in interest, you would need a rate of 16.9%.
