It take 23 mins for the drive
He needs to reach the airport by a quarter before 6
a quarter before 6 = 5.45
So he needs to leave 23 mins before 5.45
23 mins before 5.45 = 5.22
y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
Answer:HHGNHHGHHGHNHG
Step-by-step explanation:
To find the mean:
Take <span>3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together
=83
Now you divide 83 by the number of terms in the sample set, which is 20.
83/20 = 4.15
For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.
final answer= 4.2 </span><span />
Answer:
.13.5%
Step-by-step explanation:
The probability that a student will receive a grade between 74 and 76 is calculated as follows:
µ+2σ=70+2(2)=70+4=74
µ+3σ=70+3(2)=70+6=76
From the above empirical rule it can be observed that 13.5% of observations fall in between 1 and 2 standard deviations above the mean.
Therefore, the probability that a student will receive a grade between 74 and 76 is 13.5%.
Thus, the correct options is A.13.5%.
