Answer:
he will need 10.5 gallons of oil to fry all of the potatoes.
Step-by-step explanation:
He will be frying 63 potatoes. 18*(3.5)
Divide 63 by 6 because he will need a gallon for every 6 potatoes.
10.5 will be the number of gallons Hector will need.
Answer:
About 2 students own a pet iguana
Step-by-step explanation:
Step 1
Determine the expression for the total number of students that own pet iguanas as shown;
N=p×T
where;
N=total number of students that own pet iguanas
p=proportion of total students that own pet iguanas
T=total number of students
In our case;
N=unknown
p=0.3 % of students
T=610 students
replacing;
N=0.3% of 610
N=(0.3/100)×610
N=1.83, round up to 2 since 1.83 is closer to 2 than 1

Answer:
-5.2
Step-by-step explanation:
Answer:
The number of newborns who weighed between 1614 grams and 5182 grams was of 586.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean weight was 3398 grams with a standard deviation of 892 grams.
This means that 
Proportion that weighed between 1614 and 5182 grams:
p-value of Z when X = 5182 subtracted by the p-value of Z when X = 1614.
X = 5182



has a p-value of 0.9772
X = 1614



has a p-value of 0.0228
0.9772 - 0.0228 = 0.9544.
Out of 614 babies:
0.9544*614 = 586
The number of newborns who weighed between 1614 grams and 5182 grams was of 586.
