P=25r-12500
p=125000 and r=?
125000=25r-12500
+12500 +12500
25r= 137500
r=137500/25
r= 5,500
Therefore the answer is B) 5,500
Answer:
175 mL
Step-by-step explanation:
(a) Convert the mass of the cat to kilograms
1 kg = 2.20 lb
Mass = 8 lb × (1 kg/2.20 lb)
= 3.64 kg
(b) Calculate the hourly volume
V = 3.64 kg × (2 mL/1 kg)
= 7.27 mL
(c) Calculate the daily volume
V = 24 h × (7.27 mL/1 h)
= 175 mL
Answer:
The p value for this case is given by:
Since the p value is lower than the significance level we have enough evidence to conclude that the true proportion is significantly higher than 0.5 at 5% of significance.
Step-by-step explanation:
Information given
n=165 represent the random sample selected
55 represent the students indicated a belief that such software unfairly targets students
X =165-55= 110 represent students who NOT belief that such software unfairly targets students
estimated proportion of students who NOT belief that such software unfairly targets students
is the value that we want to check
represent the significance level
z would represent the statistic
represent the p value
System of hypothesis
We want to check if the majority of students at the university do not believe that it unfairly targets them, and the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
After replace we got:
The p value for this case is given by:
Since the p value is lower than the significance level we have enough evidence to conclude that the true proportion is significantly higher than 0.5 at 5% of significance.
Answer:
number of taxi accidents = 12235.2 which is approximately approximately 12235 accidents
Explanation:
The equation for the number of accidents is given as:
y = -143.3 x² <span>+1823.3 x + 6820
We are given that:
x = 0 represents 1990
x = 1 represents 1991
Therefore:
x = 8 represents 1998
Now, all we have to do is substitute with the value of x = 8 in the equation of accidents to get the number of taxi accidents in 1998 as follows:
y = </span>-143.3 (8)² +1823.3 (8) + 6820
y = -143.3 (64) + 1823.3 (8) + 6820
y = -9171.2 + 14586.4 + 6820
y = 12235.2
If we are asked to approximate the answer, then it would be approximately 12235 accidents
Hope this helps :)
