Answer:
Kanye run faster.
Step-by-step explanation:
Given that,
Time = 1 min = 60 sec
Suppose, we find the speed of kanye and Jay.
According to number line,
Kanye covers the -160m distance and Jay covers the 140 m distance.
Negative sign shows the opposite direction.
We need to calculate the speed of Kanye
Using formula of speed
Where, v = speed
d = distance
t = time
Put the value into the formula
We need to calculate the speed of Kanye
Using formula of speed
Put the value into the formula
The speed of kanye is more than jay.
Hence, Kanye run faster.
The answer is 119.8245. 49% of $234.95 is 115.1255 (.49 • 234.95 = 115.1255). Subtract $115.1255 from $234.95 to get the answer to get 119.8245 (234.95 – 115.1255 = 119.8245).
Answer:
d.)
Step-by-step explanation:
Answer: 2/3 feet
Step-by-step explanation:
Since there are 12 inches in a foot, 8 inches would be equal to 8/12 of a foot. We can divide the numerator and the denominator by 4.
8/12 = 2/3 feet
Answer:
a) The test statistic is 
b) The pvalue is 0.0060.
Step-by-step explanation:
Question a:
Ha: pB < pNY
This means that the alternate hypothesis is rewritten as:
While the null hypothesis is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis and s is the standard error
pB = 0.581, pNY = 0.832
This means that 
0 is tested at the null hypothesis:
This means that 
Standard error = 0.1
This means that 
Test statistic:
The test statistic is
Question b:
The pvalue is the probability of finding a proportion less than -0.251, that is, a difference of at least 0.251, which is the pvalue of Z = -2.51.
Looking at the z-table, Z = -2.51 has a pvalue of 0.0060
The pvalue is 0.0060.
