Answer:
Grade B score:
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 73.3
Standard Deviation, σ = 9.7
We are given that the distribution of score on test is a bell shaped distribution that is a normal distribution.
Formula:
B: Scores below the top 5% and above the bottom 62%
We have to find the value of x such that the probability is 0.62
Calculation the value from standard normal z table, we have,
We have to find the value of x such that the probability is 0.05
Calculation the value from standard normal z table, we have,
Thus, the numerical value of score to achieve grade B is
Answer:
4:3,12:9, and 16:12
Step-by-step explanation:
Answer:
Step-by-step explanation:
The only thing you need to watch carefully is the divisor which in this case is x - 3. The divisor, in synthetic division, is the number that will make the binomial go to 0.
x - 3 =0
x = 3
So the divisor is 3.
3 || 2 4 -35 15
6 30 -15
======================
2 10 -5 0
So the quotient is
2x^2 + 10x - 5 with no remainder
Since we are rounding to the nearest hundreds place in 222,977 the hundreds would be the 9. The seven behind it would make the number round up since the rule is 0-5 round down 6-9 round up. you round the 9 up to 10 so you add 1 to the next number since you cant have 222,1000. thats wrong . the answer is
223,000
Answer:
B. 6
Step-by-step explanation:
SInce the total amount paid by Mike was $24, you subtract the initial amount he paid ($6) which leaves you with $18. Since the taxi driver charges $3 per mile you divide $18 by $3 to get 6 so that means Mike travel 6 miles.
