Answer:
The probability of guessing the correct code is , If you were given ten tries to guess it.
Step-by-step explanation:
First of all, we need to find the total possible combinations due the code is composed by numbers from zero to nine are individually selected at random and combined to make a code that contains a six-digit number. So we obtain .
Then, as we have ten tries to guess, , is the probability of guessing the correct code, one out one houndred thousand.
Answer:
The balance of the loan be after one year will be $7785
Step-by-step explanation:
we are given
A college student takes out a $7,500 loan from a bank
so, P=7500
time is 1 year
so, t=1
the bank charges 3.8% interest each year
so, r=3.8%
r=0.038
now, we can use formula
where
A is amount after t years
so, we can plug values
So,
The balance of the loan be after one year will be $7785
Answer:
The correct option is;
c. Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Step-by-step explanation:
Here we have the values
μ = 275 mL
275.4
276.8
273.9
275
275.8
275.9
276.1
Sum = 1928.9
Mean (Average), = 275.5571429
Standard deviation, s = 0.921696159
We put the null hypothesis as H₀: μ₁ = μ₂
Therefore, the alternative becomes Hₐ: μ₁ ≠ μ₂
The t-test formula is as follows;
Plugging in the values, we have,
Test statistic = 1.599292
at 7 - 1 degrees of freedom and α = 0.05 = ±2.446912
Our p-value from the the test statistic = 0.1608723≈ 0.1609
Therefore since the p-value = 0.1609 > α = 0.05, we fail to reject our null hypothesis, hence the evidence suggests that the mean does not differ from 275 mL.
