The sides of the isosceles triangle are two equal legs and the remaining side is called base.
Answer:
it's 190 which mean C
Step-by-step explanation:
Answer: 32
Step-by-step explanation:
Given: The energy needed for 1 hour of running for an adult 
Therefore. the energy needed for seven hours of running=
Since, he energy released by metabolism of 1 average candy bar 
Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.=
Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.
Answer:
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Step-by-step explanation:
The population mean = μ= 7.5
Sample mean = x`= 7.3
Sample standard deviation= s= 0.6
Sample size = 87
Assuming normality we perform z test
z= x`-u/s/√n
z= 7.3-7.5/0.6/√87
z= -3.11
The critical region for 0.05 for two tailed test is z>+1.96 and Z<-1.96
Since the calculated z= -3.11 falls in the critical region Z<-1.96 we conclude that birth rate is lower in the young mothers.
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
Only choice a is correct because when n > 30 the population standard deviation and the sample standard deviation are assumed to be normal
Choice b cannot be the correct option because it is already inferred that only one baby was measured per mother.
Choice C cannot be also the best choice because it is already assumed.
Choice d is totally incorrect.
