Katie ran four miles she ran at a rate that was 1.1 miles per mile slower than Jasmine Jasmine ran at a rate of 8.4 minutes per mile for how many minutes did Katie run? Explain how you determined your answer.
Answer:
Katie spent 29.2 minutes
Step-by-step explanation:
I hope this helps!!!
Answer:
29.2 minutes
Step-by-step explanation:
If Jasmine ran 5 miles in 42 minutes. Katie ran 4 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer. So basically When you run slower you subtract so 8.4 minus 1.1 is 7.3. And then multiply it by 4 and get 29.2 You can check your answer by dividing 29.2 by 7.3
Identify the given random variable as being discrete or continuous. The number of phone calls between New York and California on Thanksgiving day Group of answer choices Discrete
Answer:
Discrete
Step-by-step explanation:
Given
Number of phone calls between two cities on Thanks giving day
Required
Discrete or Continuous
Number of phone calls can be represented as thus:
0, 1, 2 , 3 , 10, 20, 100 or any other positive whole numbers
Only discrete data take form of the above.
Hence, "Discrete" answers the question
The given random variable is discrete and this can be determined by observing the given data.
Given :
The number of phone calls between New York and California on Thanksgiving day.
The following steps can be used in order to determine the given random variable as being discrete or continuous:
Step 1 - According to the given data, the number of phone calls between New York and California on Thanksgiving day.
Step 2 - So, the total number of calls on thanksgiving day may be 0, 2, 6, 9, 15, 100, 115, or whole positive number.
Step 3 - So, from the above steps, it can be concluded that the given random variable is discrete.

at a simple annual interest rate of 4.5 percent, haw many years will it take Sam to earn 135 dollars on an original account of 1,000
9514 1404 393
Answer:
3
Step-by-step explanation:
The simple interest formula is useful here:
I = Prt
where I is the interest earned on principal P invested at rate r for t years.
Filling in the given information, we can solve for the unknown.
135 = 1000·0.045·t
135/45 = t = 3
It will take 3 years for Sam to earn $135 on his account.

An article presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 160 kN load on a runway with a subbase thickness of 864 mm, the average surface deflection was 2.34 mm with a standard deviation of 0.090 mm. Find a 90% confidence interval for the mean deflection caused by a 160 kN load. Round the answers to three decimal places. The 90% confidence interval is ( , ).
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean.
Given that: sample size (n) = 6, standard deviation (σ) = 0.09 mm, mean (μ) = 2.34 mm
The confidence interval = 90% = 0.9
α = 1 - 0.9 = 0.1
α / 2 = 0.05
The z score of 0.05 is the same as the z score of 0.45 (0.5 - 0.05) which is 1.645.
The margin of error is given as:
[tex]E=Z_{\frac{\alpha}{s} }*\frac{\sigma}{\sqrt{n} }[/tex]
[tex]E=1.645*\frac{0.09}{\sqrt{6} }=0.06\ mm[/tex]
The confidence interval = μ ± E = 2.34 ± 0.06 = (2.28, 2.40)
The confidence interval is between 2.28 mm and 2.4 mm

How many grams are in 1.204 x 10 24 atoms lithium
Answer:
We have:
1.204x10^24 atoms of lithium.
The weight of one atom of lithium is: 6.941 atomic mass units.
And we know that:
1 atomic mass unit = 1.661x10^(-24)g
Then the mass of one atom is 6.941 times 1.661x10^(-24)g
m = 6.941*1.661x10^(-24)g = 1.153x10^(-23)g
Then the mass of 1.204x10^24 atoms is 1.204x10^24 times 1.153x10^(-23)g
M = 1.204x10^24 *1.153x10^(-23)g = 1.388x10^(24 - 23) g
M = 1.388x10^1g = 13.88 g
Then 1.204x10^24 atoms of lithium wieght 13.88 grams.
Solve the equation. Then check your solution.

Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
