Step-by-step explanation:
Answer:
3.10 * 72
Step-by-step explanation:
To find 310% of 72
Of means multiply and is means equal
310% * 72 = answer
Change to decimal form
3.10 * 72 = answer
223.20
Answer:
Step-by-step explanation:
For the null hypothesis,
H0 : p = 0.63
For the alternative hypothesis,
Ha : p < 0.63
This is a left tailed test
Considering the population proportion, probability of success, p = 0.63
q = probability of failure = 1 - p
q = 1 - 0.63 = 0.37
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 478
n = number of samples = 800
P = 478/800 = 0.6
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.6 - 0.63)/√(0.63 × 0.37)/800 = - 1.76
From the normal distribution table, the area below the test z score in the left tail 0.039
Thus
p = 0.039
Equation represents the difference in the number of foreign and domestic stamps Malik collected: X-34=y
equation represents the total number of stamps Malik collected:
212 = X-34-y
so,
245= X-Y
Situation :
Y= X-34
X-Y= 245
