Answer:
14 = 8 + 2d
Step-by-step explanation:
Odometer is a device that is equipped in the vehicles to count the distance traveled by the vehicle.
It has been given in the question that,
Distance between beach and her friend's house = d miles.
Distance between Brenna's house and her friend's house = 8 miles
Total distance traveled by Brenna = 14 miles.
Starting from the Brenna's house, we will add each distance traveled till the end of her journey and will make it equal to the 14 miles.
So,
Total distance = Distance between Brenna's house and her friend's house + Distance between her friend's house and beach + Distance between beach and her friend's house
Thus, we can now put the values as,
14 = 8 + d + d
We will get the final equation as
14 = 8 + 2d
Answer:
16
Step-by-step explanation:
Average = the sum of all numbers divided by the amount of items in the set, so:
10+30=40
40/2=20
20-4=16
Hopefully this helps :) Good luck!
Answer:
13.567%
Step-by-step explanation:
We solve the above question, using z score formula
z = (x-μ)/σ, where
x is the raw score = 23.1 ounces
μ is the population mean = 22.0 ounces
σ is the population standard deviation = 1.0 ounce
More than = Greater than with the sign = >
Hence, for x > 23.1 ounces
z = 23.1 - 22.0/1.0
= 1.1
Probability value from Z-Table:
P(x<23.1) = 0.86433
P(x>23.1) = 1 - P(x<23.1)
P(x>23.1) = 1 - 0.86433
P(x>23.1) = 0.13567
Converting to percentage
= 0.13567 × 100
= 13.567%
Therefore, the percentage of regulation basketballs that weigh more than 23.1 ounces is 13.567%
