Every year, a dog sled race is held in Alaska and is approximately 1,150 miles in distance. Information about the top three racers is
listed below.
• Aaron completed half the race in approximately 4 days, 12 hours.
• Dallas finished the race in approximately 8 days, 18 hours.
• Mitch completed one-quarter of the race in approximately 2 days, 5 hours.
Answer:
Aaron completed the race in 9 days. Mitch finished in the race in 8 days 20 hours. Dallas finished in 8 days 18 hours
Step-by-step explanation:
1. Dallas won the race. 8 days 18 hours
2. Mitch came in second. 2 days 5 hours x 4= 8 days 20
3. Aaron was 3rd. 4 days 12 hours x 2= 9 days
Suppose that 11% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). Consider a random sample of 200 shafts, and let X denote the number among these that are nonconforming and can be reworked. (Round your answers to four decimal places.) (a) What is the (approximate) probability that X is at most 30
Answer:
0.9726 = 97.26% approximate probability that X is at most 30
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
11% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).
This means that [tex]p = 0.11[/tex]
Random sample of 200 shafts
This means that [tex]n = 200[/tex]
Mean and Standard deviation:
[tex]\mu = E(x) = np = 200*0.11 = 22[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{200*0.11*0.89} = 4.42[/tex]
(a) What is the (approximate) probability that X is at most 30
Using continuity correction, this is [tex]P(X \leq 30 + 0.5) = P(X \leq 30.5)[/tex], which is the pvalue of Z when X = 30.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30.5 - 22}{4.42}[/tex]
[tex]Z = 1.92[/tex]
[tex]Z = 1.92[/tex] has a pvalue of 0.9726.
0.9726 = 97.26% approximate probability that X is at most 30

1 kilogram of bananas for $2.06 or 4 kilogram of bananas for $7.48
PLZ EXPLAIN PLZ
Answer: 4 kilograms of bananas for $7.48
Step-by-step explanation:
Unit price for 1 kilo= $2.06
2.06 x 4 = 8.24
Unit price for 4 kilo= $1.87
2.06 > 1.87
So, 4 kilograms of bananas is the better buy.
Simple form:
Answer 1: 2.06
Answer 2: 1.87
Answer 3: greater than
Answer 4: 4 kilograms of bananas for $7.48

The circumference of a circle is 7xm.
What is the area of the circle?
A. 3.57x m²
B. 12.257x m2
C. 147xm2
D. 497xm2
Answer:
A = 3.57 m²
Step-by-step explanation:
Given that,
The circumference of a circle is 7xm.
The expression for the circumference of a circle is given by :
[tex]C=2\pi r[/tex]
r is the radius of the circle
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{7}{2\times \dfrac{22}{7}}\\\\r=1.11\ m[/tex]
The area of a circle is given by :
[tex]A=\pi r^2\\\\A=3.14\times (1.11)^2\\\\A=3.89\ m^2[/tex]
Out of given option,
A = 3.57 m²
So, the area of the circle is 3.57 m².

Answer:
D = 45 and C = 26
Step-by-step explanation:
The bigger triangle has a 90 degree corner add that to 64 and you will get 164 (all of the triangles angles have to add to 180) from 180 subtract 164 and you get 26 which is C's answer
For D just divide 90 by 2 (90/2)=45
Answer: The person up their is correct
D = 45 and C = 26
Step-by-step explanation:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

et X represent the full height of a certain species of tree. Assume that X has a normal distribution with a mean of 191.8 ft and a standard deviation of 4 ft. A tree of this type grows in my backyard, and it stands 182.2 feet tall. Find the probability that the height of a randomly selected tree is as tall as mine or shorter.
Answer:
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = 0.0082
Step-by-step explanation:
Step(i):-
Mean of the Population = 191.8 ft
Standard deviation of the Population = 4 ft
Let 'X' be the random variable in normal distribution
X = 182.2 feet
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{182.2-191.8}{4} = -2.4[/tex]
Step(ii):-
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = P( z≤ -2.4)
= 1-P(z>2.4)
= 1-(0.5 + A(2.4))
= 0.5 - A(2.4)
= 0.5 - 0.4918
= 0.0082
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = 0.0082
