Gabrielle took a Spanish test with 50 questions. She answered 50 questions but only answered 44 of them correctly. What percent of the questions did Gabrielle answer correctly?
The fraction represents the 44 questions that Gabrielle got correct out of the 50 questions she answered altogether.
To find out what percent of questions Gabrielle answered correctly, we can turn into a percent.
We can first reduce the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 44 and 50 using 2.
44 ÷ 2 = 22
50 ÷ 2 = 25
22 ÷ 25 = 0.88
0.88 × 100 = 88%
Therefore, Gabrielle answered 88% percent of the questions correct on her Spanish test.

Answer:
Options A, B and C are correct.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
From the Central Limit Theorem, we have that:
The larger the sample size, the closer to the normal distribution the distribution of sample means is.
No matter the sample size, the mean is the same.
The larger the sample size, the smaller the standard deviation.
The smaller the sample size, the larger the standard deviation.
So the correct options are:
A, B, C
Hello!
The answer is: 15 mL
Why?
From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):
So,
a day
We also know that there are 50 mg cefaclor every 1mL,
So, to know how many mL will be given with 750mg, we just need to divide it by 50
Therefore,
15mL or 750 mg of cefaclor will be given each day.
Have a nice day!
