Answer:
12.5%
Step-by-step explanation:
I think it's 2 days converted to hours to get 48hrs
6/48×100 to make it a percentage
Answer would be 12.5%
Well that's according to my thinking
Answer:
-25,-25
Step-by-step explanation:
5 to the second is 25 . because 5 times 5 is 25
Answer:
$142 ; 0.749 ; Normal ; 0.090938
Step-by-step explanation:
Mean and standard deviation :
The mean of the distribution x = $142, because the sample size is sufficiently large, the distribution will be approximately normal (central limit theorem).
Standard deviation of distribution : σ/ sqrt(n)
= 29 / sqrt(1500)
= 0.749
B.)
Shape of sampling distribution of X.
The shape of the sampling distribution will be approximately normal due to the large sample size used. This is according to the central limit theorem whereby distribution of sample converges to normal with increasing sample size. Mean ~ N(142, 0.749²)
C.)
P(X > 143)
Using the relation :
Z = (x - mean) / standard error
Z = 143 - 142) / 0.7489
Z = 1.335
P(Z > 1.335) :
Using the Z probability calculator :
P(Z > 1.335) = 0.090938
False, it can have none when the line does not touch the parabola, one when the line touches at one point, and 2 when the line intersects in two places.
Hey! Ok so with this problem, you can figure out the pattern with subtraction.
If you convert the fractions to decimals you get 3.25 and 5.625.
5.625 - 3.25 = 2.375, which means he increased his run by 2.375 miles.
8 - 5.625 = 2.375 as well, which follows the pattern. So what you would need to do from here is add 2.375 miles for each day he jogged.
8 + 2.375 = 10. 375, the miles he jogged on thursday.
10.375 + 2.375 = 12. 75, the miles he jogged on friday.
So, when converted to fractions, your answer is D: Eric jogged 12 3/4 miles on Firday
