To solve this problem, we need to set up a proportion.
2 batches of nut bars/ 4 eggs = 1 batch of nut bars / x eggs.
To solve this proportion, we use cross products, or multiplying the numerator of one number by the denominator of the other and setting them equal to one another.
(4 eggs) (1 batch) = (2 batches) (x eggs)
4= 2x
2=x
Therefore, 2 eggs are used in each batch of nut bars.
Answer: e) 6
Step-by-step explanation:
Let x be mother + children = 18
Father's age = 38
Average age of the family = 14
38 + 18x /( x + 1 )= 14
Opening the bracket
38 + 18x = 14x + 14
Collecting like terms
24 = 4x
x = 6
no of children in the family is 6.
Answer:
Step-by-step explanation:
a. The five-number summary is made up of the following summary means:
1. Minimum: 25
2. First Quartile: 30.5
3. Medium: 34.5
4. Third quartile: 43
5. Maximum: 78
6. P30: 32.1
b.
Standard Deviation: 12.72
Rank: 53
Interquartile range: 12.5
C. The interquartile range is 12.5 and 1.5 times the interquartile range is (1.5) (12.5) = 18.75. Third quartile plus 1.5 times the interquartile range is 61.75. The value of 78 exceeds 61.75, then 78 is an outlier.
