Answer:
Total number of Hyenas is 19
Step-by-step explanation:
Given
Total number of Lion + Hyenas= 34
Let Number of Hyenas be x
Number of Lions = 34 -x
Now According to question
Each lion eats 4 antelope + Each Hyena eats 3 antelope = 117
Hyenas = 19
Lions = 34-19 = 15
Answer:
Step-by-step explanation:
<u>Factoring</u>
We need to recall the following polynomial identity:
The given expression is:
To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:
Now we apply the identity:
Operating:
The remaining factors cannot be factored in anymore. Thus the completely factored form is:
Answer:
Area = B x H + L (sum of sides of triangle)
= 9 x 12 + 10 (12 + 15 + 9)
= 108 + 360
=
Either your options are wrong or question is to find lateral surface.
Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.
Lateral Surface Area = (12 + 15 + 9) x 10
=
Answer:
12
Step-by-step explanation:
divide 28 by 7 giving you 4 then multiple that by 3
Using the normal distribution, it is found that 44.43% of students are 21 or older and thus old enough to legally order alcohol at Griff's.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of students that are 21 or older is <u>one subtracted by the p-value of Z when X = 21</u>, hence:
Z = 0.14
Z = 0.14 has a p-value of 0.5557.
1 - 0.5557 = 0.4443 = 44.43% of students are 21 or older and thus old enough to legally order alcohol at Griff's.
