Answer:
15°C
Step-by-step explanation:
Use the following formula to convert Fahrenheit to Celsius:
Substitute the value for the variable and solve for C.
Therefore, 59°F is equivalent to 15°C.
Answer: 5
Step-by-step explanation:
Given:
The insect population function is:
Where x is the number of weeks.
To find:
The population after 4 weeks.
Solution:
The population of insect after x weeks is given by:
We need to find the population after 4 weeks.
After substituting , we get
The population after 4 weeks is 160. Therefore, the correct option is C.
Step-by-step explanation:
1)
2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =
= 2 13/100
2)
2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =
= 713/100 = 7 13/100
3)
2.1 + 00.3 = 2.4
or did you mean + 100.3 ? then is is 102.4
4)
24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50
5)
3 24/100 + 8 7/10 =
= 300/100 + 24/100 + 800/100 + 70/100 =
= 1194/100 = 11 94/100 = 11 47/50
Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
