vehicle speed on a particular bridge in china can be modeled as normally distributed. (a) if 5% of all vehicles travel less than 39.18 m/h and 10% travel more than 73.27 m/h, what are the mean and standard deviation of vehicle speed? (round your answers to three decimal places.) mean standard deviation
The mean and standard deviation of the vehicle speed are 58.33 and 11.64 respectively.
The vehicle speed on a particular bridge in china has normal distribution.
5% represents the 5th percentile which is here, 39.18 m/h.
Since 10% travels more than 73.27 m/h, 90% travels less than 73.27 m/h.
So here the 90th percentile is 73.27 m/h.
Also the z-score, z = (x-μ)/σ, where μ is the mean of normal distribution and σ, the standard deviation.
So 39.18 corresponds to the z with p-value 0.05, i.e., z = -1.645 [from the normal tables]
Hence, z = (x-μ)/σ
⇒ -1.645 = (39.18 - μ)/σ
⇒ -1.645σ = 39.18 - μ
⇒ μ = 39.18 + 1.645σ ----------(1)
Also 73.27 corresponds to the z with p-value 0.9,i.e., z = 1.28.
Hence , z = (x-μ)/σ
⇒ 1.28 = (73.27 - μ)/σ
⇒ 1.28σ = 73.27 - μ
⇒ μ = 73.27 - 1.28σ ----------(2)
Equating (1) and (2), we get,
39.18 + 1.645σ = 73.27 - 1.28σ
2.925σ = 34.05
σ = 11.64
hence μ = 39.18 +1.645 x 11.64
⇒ μ = 58.33

Find the area under the standard normal curve between z=â1.16 and z=â0.03 Round your answer to four decimal places, if necessary.
The area under the standard normal curve between z=â1.16 and z=â0.03 is 0.3663.
To find the area under the standard normal curve between z = -1.16 and z = -0.03, we will use the following steps:
1. Look up the z-values in the standard normal distribution table (or use a calculator or online tool that provides the corresponding probability values).
2. Subtract the probability value for z = -1.16 from the probability value for z = -0.03.
3. Round your answer to four decimal places.
Step 1: Look up the z-values in the standard normal distribution table.
- For z = -1.16, the corresponding probability value is 0.1230.
- For z = -0.03, the corresponding probability value is 0.4893.
Step 2: Subtract the probability values.
Area = P(-0.03) - P(-1.16) = 0.4893 - 0.1230
Step 3: Round the answer to four decimal places.
Area = 0.3663
So, the area under the standard normal curve between z = -1.16 and z = -0.03 is approximately 0.3663.

what would be an appropriate significance level (alpha level) for a hypothesis test where the severity of type i error is high? a 0.05 b 0.001 c 0.95 d 0.999 e 0.75
If the severity of Type I error is high, meaning that it would be very costly or harmful to falsely reject the null hypothesis, then a more stringent alpha level would be appropriate. In this case, option b, 0.001, would be the most appropriate significance level as it would minimize the chance of a Type I error occurring.
An appropriate significance level (alpha level) for a hypothesis test where the severity of Type I error is high would be a lower alpha value. This is because a lower alpha level reduces the likelihood of committing a Type I error (incorrectly rejecting the null hypothesis).
In this case, the appropriate significance level among the given options is:
b) 0.001
A lower alpha level like 0.001 indicates that there is a smaller chance of committing a Type I error, making it more suitable when the severity of Type I error is high.

please help, i don’t know how to do this. (it’s geometry)
Step-by-step explanation:
there are many people that find geometry easier, because here you can actually "touch" something and "see" what we are doing and dealing with.
anyway,
let's just remember what a parallelogram is and represents :
it has 2 pairs of parallel sides (the sides in each pair are parallel to each other). hence the name.
in order for that to be possible the sides in every pair must be equally long. in our case here : FG = EH, FE = GH.
the diagonals cross each other at their midpoints.
and then we see in the graphic how the diagonals split the the whole parallelogram into 4 triangles.
so, now we have all tools to solve the puzzles.
we know, I is the midpoint of both diagonals. and therefore, EI = IG, FI = IH
and that means
3x - 1 = 8
3x = 9
x = 3
the triangles FIG and EIH are congruent. that means, if you turn them to be oriented in the same direction and then place them on top of each other, they would cover each other perfectly.
and that means that they have the same angles and side lengths.
therefore, when we know things about one of these triangles, we know the same things about the other triangle. like the angles.
so, the angle IHE = IFG = 31°
the angle IEH = IGF = 46°
why do we know the 2 triangles are congruent ?
because the 3 sides of FIG are exactly as long as the 3 sides in EIH :
FG = EH
IG = EI
FI = IH
and that satisfies the SSS criteria (side-side-side) for congruent triangles.
and again, therefore, the angles must be the same too.
Matthew wants to take out a loan to buy a car. He calculates that he can make repayments of $35,000 per year. If he can get a six-year loan with an interest rate of 9.25%, what is the maximum price he can pay for the car?
The maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.
To determine the maximum price Matthew can pay for the car, we need to consider his repayment capability and the terms of the loan.
Matthew can make annual repayments of $35,000. Since the loan term is six years, the total amount he can repay over the loan period is $35,000 multiplied by six, which equals $210,000.
To calculate the maximum price of the car, we need to account for the interest rate of 9.25%. The interest rate represents the cost of borrowing and is applied to the loan amount.
Let's assume the loan amount is denoted by P.
The formula to calculate the future value of a loan with interest is:
FV = P(1 + r)^n
Where:
FV = Future value (total amount repaid)
P = Principal amount (maximum price of the car)
r = Interest rate per period (9.25% or 0.0925)
n = Number of periods (six years)
Since Matthew can repay a total of $210,000 over the loan period, we can set up the equation:
$210,000 = P(1 + 0.0925)^6
Now we can solve for P:
P = $210,000 / (1 + 0.0925)^6
Evaluating this expression, we find:
P ≈ $126,318.29
Therefore, the maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

Answer: The volume is 10 cm^3
Step-by-step explanation:
We know that each cube is a centimeter cube.
This means that if L is the length of each side of one of these cubes, then L = 1cm
And we know that the volume of a cube of side length L is:
V =L^3
Then the volume of each of the small cubes is:
V = (1 cm)^3 = 1 cm^3
Now we just need to count the number of cubes in the prism.
We can see that there is a "T" shape.
in the front part, we can see 5 cubes.
And there is another part in the back, where we also can assume that there are 5 cubes.
Then the total number of cubes in the prism is 10
And each of these cubes is 1 cm^3
Then the volume of the prism is 10 times 1 cm^3
The volume of the prism is:
V = 10*(1 cm^3) = 10 cm^3
Identify whether the function graphed has na odd or even degree and a positive are negative leading cooefficient
To determine if the degree of the function is odd or even we need to look at the extrema of the graph. If both points to the same side, it is, if X goes to positive infinity or to negative infinity, to both direction Y of the graph is going to the same direction, it means that the degree os even. Otherwise, when the extrema are pointing in different directions, it means the degree is odd.
In the present graph, the degree is odd, because the graph has different directions for each extrema.
To determine the signal to the leading coeficient, we check the direction Y is going to increasing values of X. If Y goes positive, the leading coeficient is positive, if it is negative, the leading coeficiente is negative.
In the present graph, the leading coeficient is positive, because for increasing values of X we have increasi

suppose w is a subspace of rnspanned by n nonzeroorthogonal vectors. explain why w d r
As W is spanned by n linearly independent vectors in ℝ^n, it means that the dimension of W is also n. This implies that W has the same dimension as ℝ^n, and therefore, W is equal to ℝ^n.
If w is a subspace of rnspanned by n non zero orthogonal vectors, then w is at most n-dimensional because there are only n vectors that can be used to span w. Any vector outside of the span of these n vectors will not be in w. Therefore, the dimension of w is less than or equal to n. Since w is a subspace of rn, which is n-dimensional, w must be a subset of Rn with a dimension less than or equal to n. Therefore, w d Rn. Suppose W is a subspace of ℝ^n spanned by n nonzero orthogonal vectors. This means that W is a vector space that is a subset of ℝ^n, and it can be generated by taking linear combinations of the n nonzero orthogonal vectors. Since the vectors are orthogonal, they are linearly independent, and their linear combinations form a basis for the subspace W.
