Answer: A)Sale for two weeks =Rs. 686,659. b)\Kriti books had greater sales in the second week than the first by Rs.114877
Step-by-step explanation:
Price of books sold in the first week=Rs.285891
Price of books sold in the second week=Rs.400768
Total Amount of books sold in the two weeks=Rs.285891 +Rs.400768 =
Rs. 686,659.
Fro the question, we can see that Kriti books store has more sales in the second week.
Which is greater than in the first week by Rs.114877
Rs.400768 -Rs.285891 =Rs.114,877
If this male is 5 ft 9 inches tall, he is 9 inches over five feet tall. Thus, h = 9.
Evaluate 6.2(20+h):
6.2(20+9) = 6.2(29) = 179.8 lb.
Answer:
a. 0.1917
b. 0.0914
d. 0.1580
Step-by-step explanation:
(a)
Mean, 
= 0.375 -0.1833 = 0.1917
(b) sample prop ? Show your work and label each value.
Mean, = = 0.1917
Standard deviation = 
Standard deviation = 
Standard deviation = 0.0914
(c)
Normality condition:
np ≥ 10 and n(1-p) ≥ 10
Both the samples satisfy the normality condition.
(d)
The probability is obtained by calculating the z score,
= 1.0029
P(z > 1.0029) = 1 - P(z ≤ 1.0029)
The probability is obtained from the z distribution table,
P(Z > 1.0029) = 1 - 0.8420 = 0.1580
Answer:
If the first number is x and y is the second number
x = 11
y = 18
Step-by-step explanation:
If x is the first number and y is the second number then:
x + 7 = y
The sum of the two numbers is expressed as:
x + y = 29
In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation
x + y = 29
x + (x + 7) = 29
2x + 7 = 29
2x + 7 - 7 = 29 - 7
2x/2 = 22/2
That means x equals 11
Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y
11 + 7 = y
y = 18
