Answer:
The sweat chloride reference value is less than 30 mmol/L. A value of more than 60 mmol/L of chloride in the sweat is consistent with a diagnosis of cystic fibrosis. The values of 30-60 mEq/L may represent heterozygous carriers, these carriers cannot be accurately identified with a sweat chloride test.
Answer: 38.41 minutes
Step-by-step explanation:
The standard error for the difference in means is given by :-

where ,
= Standard deviation for sample 1.
= Size of sample 1.
= Standard deviation for sample 2.
= Size of sample 2.
Let the sample of Latino name is first and non -Latino is second.
As per given , we have


The standard error for the difference in means will be :




Hence, the standard error for the difference in means =38.41 minutes
6/42 in simplest form :
Divide both the nominator and the denominator by the HCF (highest common factor) : 6
6/42 = 6:6/42:6 = 1/7
Answer:
x < 8
Step-by-step explanation:
x= # of hikes
3x +16 =5x
-3x. -3x
16=2x
16/2= 8
2x/2= x
8=x
x=8
check:
3(8) +16 =5(8)
24 +16 =40
40=40 ✓
there for at 8 hikes with either deal it would be the same but if you went up a number of hikes for the first option it would only be $43.00 spent in total. but with the second option it would be $45.00.
