Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.
What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?
3.5
3.25
0.75
0.25
Answer:
0.25
Step-by-step explanaition:
The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

Lily likes to collect records. Last year she had 10 records in her collection. Now she has 13 records. What is the percent increase of her collection?
Answer:
30%
Step-by-step explanation:
We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.
13/10 = 1.3
1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)
0.3 = 3/10 = 30%

The Mackinac Bridge in Michigan is the third-longest suspension bridge in the United States.
a. How high above the water is the roadway in meters? Round to the nearest hundredth.
The roadway is about ____ meters above the water.
Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.
The length of the bridge is about ____ kilometers.
The roadway is about 60.66 meters above the water.
The length of the bridge is about 8.04 kilometers.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
The length of the roadway above the water = 199 ft
1 ft = 0.3048 m
Multiply 199 on both sides.
199 ft = 60.66 m
The bridge has a length of 26,372 feet.
1 ft = 0.0003048
Multiply 26372 on both sides.
26372 ft = 26372 x 0.0003048
26372 ft = 8.04 km
Thus,
The roadway in meters is about 60.66 meters above the water.
The length of the bridge in km is about 8.04 kilometers.

What type of triangle is this triangle?
acute scalene
obtuse isosceles
obtuse scalene
acute isosceles
Answer:
Obtuse scalene
Step-by-step explanation:
Answer:
obtuse scalene
Step-by-step explanation:
Scalene means that none of the sides are equal.
Isosceles means that two of the sides are equal.
Obtuse means an angle in the triangle is larger than 90 degrees.
Acute means all angles in the triangle are smaller than 90 degrees.
None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.

Tell whether x and y are in a proportional relationship. If so, find the unit rate. Let y be the temperature x hours after midnight. The temperature is 60∘F at midnight and decreases 2∘F every 1/2 hour
Answer:
x and y are not in a proportional relationship
Step-by-step explanation:
The temperature is 60 F at midnight, and decreases 2 F every 1/2 hour, x represents hours, y represents temperature.
Plot (0, 60) , (0.5, 58) , and (1, 56)
Draw a line through the prints.
The graph is a line that does not pass through he origin.
SO, x and y are not in a proportional relationship.
