Answer: Candace ate 
servings.
Step-by-step explanation:
Given: Candace ate 
cup of cereal.
The box of cereal states that 1 serving of cereal = 
cup.
i.e. 1 cup = 
servings [Multiply both sides]
⇒ 
cup = 
servings
= servings [which is the number of servings she ate]
Hence, Candace ate servings.

Answer:
a.) 0.1685
b.) 0.7922
Step-by-step explanation:
This question is solved by the probability distribution formula for selection which uses the combination formula to derive the answer.
If 7 out of 12 cases Of refrigerators are said to have compressor problem, then the success rate to be used in the probability distribution formula = p = 7/12 = 0.583
Probability of failure = q = 0.417
When choosing r samples from a possible n sample, then probability distribution formula is denoted by :
P(X=r) = nCr × p^n × q^n-r
a.) From possible 6 samples, if P(X=5)
P(X=5) = 6C5 × 0.583^5 × 0.417¹
P(X=5) = 0.1685
b.) P(X≤4) =1 -P(X>4) = 1 - P(X=5) - P(X=6)
P(X=5) as calculated earlier = 0.1685
P(X=6) = 6C6 × 0.583^6 × 0.417^0
P(X=6) = 0.0393.
Hence, P(X≤4) = 1- 0.1685 - 0.0393
P(X≤4) = 0.7922
Answer:84
Step-by-step explanation:Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.
For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?
The rule of three is:
5.25 feet - 8 feet
x feet - 128 feet
Applying cross multiplication:
The height of the lighthouse is of 84 ft.
