Answer:
Partial products are 300, 150, 20 and 10. The value of 15×32 is 480.
Step-by-step explanation:
We need to find the partial products of 15×32.
First write each number as the sum of their place values.
Now, write 10 and 5 in first row, and 30 and 2 in first column as shown below:
10 5
30 30×10=300 30×5=150
2 2×10=20 2×5=10
Therefore partial products are 300, 150, 20 and 10.
Add these partial product to get the value of product.
The value of 15×32 is 480.
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
