Answer:
12 units
Step-by-step explanation:
Notice that as we go from Q to R, x (the horizontal distance) increases by 12 and y (the vertical distance) does not change. Thus, the distance between the two points is merely the horizontal distance, 12 units.
I think you are right, it is (1,1).

Answer:
$3600
Step-by-step explanation:
In each case, the repair cost exceeded the deductible, so your out-of-pocket cost for 2 repairs is ...
2 × $1050 = $2100
In addition, you had to pay the premium of $750 per 6-month period, or $1500 per year, so your total was ...
$2100 +1500 = $3600 . . . out-of-pocket total
Answer:
The probability is 0.9938
Step-by-step explanation:
In this question, we are asked to calculate the probability that the mean blood pressure readings of a group of people is less than a certain reading.
To calculate this, we use the z score.
Mathematically;
z = (mean - value)/(standard deviation/√N)
From the question, we can identify that the mean is 125, the value is 123 , the standard deviation is 9.6 and N ( total population is 144)
Let’s plug these values;
z = (125-123)/(9.6/√144) = 2.5
Now we proceed to calculate the probability with a s score less than 2.5 using statistical tables
P(z<2.5) = 0.9938
