Answer:
180,000 m
Step-by-step explanation:
There are 60 seconds in a minute, so:
2 min × 60 s/min = 120 s
Distance = rate × time
d = 1500 m/s × 120 s
d = 180,000 m
Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.
Answer:
Step-by-step explanation:
Given that:
sample size n = 36
standard deviation = 10.1
level of significance ∝ = 0.10
The null hypothesis and the alternative hypothesis can be computed as follows:


The test statistics can be computed as follows:





degree of freedom = n - 1 = 36 - 1 = 35
Since this test is two tailed .
The P -value can be determined by using the EXCEL FUNCTION ( = 2 × CHIDIST(35.7035, 35)
P - value = 2 × 0.435163515
P - value = 0.8703 ( to four decimal places)
Decision Rule : To reject the null hypothesis if P - value is less than the 0.10
Conclusion: We fail to reject null hypothesis ( accept null hypothesis) since p-value is greater than 0.10 and we conclude that there is sufficient claim that the normal range of pulse rates of adults given as 60 to 100 beats per minute resulted to a standard deviation of 10 beats per minute.
