Answer & Step-by-step explanation:
37.
Linda walked 3/4 (or 75%) of a track which is 3.5 miles long
Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)
38.
We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)
1/8 is 0.125
2/8 is 0.25
3/8 is 0.375
The track is 2.375 miles long.
Multiply 2.375 by 2.5
The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)
There correct answer to that question is 22.45
Answer:
The probability that in a one-game playoff, her score is more than 227 is 0.4404.
Step-by-step explanation:
We are given that Susan has been on a bowling team for 14 years. After examining all of her scores over that period of time, she finds that they follow a normal distribution. Her average score is 225, with a standard deviation of 13.
<em>Let, X = scores over that period of time</em>
X ~ N(
)
The z score probability distribution is given by;
Z = 
~ N(0,1)
where, 
= average score
= standard deviation
So, probability that in a one-game playoff, her score is more than 227 is given by = P(X > 227)
P(X > 227) = P( < 
) = P(Z > 0.15) = 1 - P(Z 
0.15)
= 1 - 0.55962 = 0.4404
Therefore, probability that in a one-game playoff, her score is more than 227 is 0.4404.
Answer:
75%
Step-by-step explanation:
To find the percentage, you would divide the training hourly rate by Martin's regular hourly rate and multiply the quotient by 100
If martin normally earns $20 and he earns $15 during training, that means you would divide 15 by 20.
15/20=.75 and .75x100=75, so Martin earns 75% of his regular hourly rate during training
Please mark as brainliest ;)
Answer:
72
Step-by-step explanation:
You need to add the two middle numbers then divide them by two.
Hope this helps.
