The distance a vehicle travels can be found by using the formula d = rt, where d is the total distance traveled, r is the rate of speed, and t is the amount of time spent traveling. Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour. To the nearest hour, how many hours does she spend driving?
Answers
Answer:
She spends 2 hours driving.
Step-by-step explanation:
The formula given is:
In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.
Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.
This means that
To the nearest hour, how many hours does she spend driving?
We have to find t. So
Rounding to the nearest hour
She spends 2 hours driving.

Answer:
The probabilities of Type I is 0.10.
The probability of type II error is 0.3
Step-by-step explanation:
Consider the provided information.
Type I error: If we reject the null hypothesis when null hypothesis is true then it is called type I error.
The type I error is denoted by α.
Type II error: If we fail to reject the null hypothesis when null hypothesis is false then it is called type II error.
The type II error is denoted by β.
It is given that significance level α = 0.10.
Thus, the probabilities of Type I is 0.10.
The power of the test is:
It is given that power is 0.7.
Therefore,
Hence, the probability of type II error is 0.3

Answer: Write an augmented matrix for the system. Then state the dimensions. x+8y−7z=12 5x+9y+5z=15 6z−3y−8x=1
Step-by-step explanation: x+8y-7z=12 5x+9y+5z=15 6z-3y-8x=1. - 18028782.
Final answer:
The system of equations provided can be converted into an augmented matrix as follows: [[1, 8, -7, 12], [5, 9, 5, 15], [-8, -3, 6, 1]]. The dimensions of this matrix are 3x4.
Explanation:
The provided system of equations is:
1. x + 8y - 7z = 12
2. 5x + 9y + 5z = 15
3. -8x - 3y + 6z = 1
We can represent this system as an augmented matrix by aligning the coefficients of the variables and the constants. The augmented matrix is:
[[1, 8, -7, 12], [5, 9, 5, 15], [-8, -3, 6, 1]]
The dimensions of this matrix represents the number of rows and columns it has. In this case, this matrix is a 3x4 matrix because it has 3 rows and 4 columns.
