Answer:
The correct answer is C. 54.
Step-by-step explanation:
Since Danielle started her postcard collection with 6 cards that she received from her uncle during his trip to France, and Danielle's uncle sends her 2 more cards each month as he travels for business, and the table below shows the relationship between the number of months Danielle has been collecting cards and the number of cards she has.
Number of Months Danielle
Has Been Collecting Cards Number of Cards in the
Collection
2 10
4 14
8 22
24?
To determine how many cards Danielle can expect to have after 24 months, the following calculation must be performed:
(24 x 2) + 6 = X
48 + 6 = X
54 = X
Therefore, after 24 months Danielle will have 54 cards.
Answer:
=k=0.25h-7/12
Step-by-step explanation:
4(h-3k)=h+7
=4h-12k=h+7
collecting like terms and leaving characters with k on 1 side, we get;
12k=3h-7
=k=0.25h-7/12
Answer:
a) bb, bg, gb, gg
b) 25% probability of getting two green dash eyed children.
c) 50% probability of getting exactly one blue dash eyed child and one green dash eyed child.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Total of eight outcomes.
a. Construct a similar sample space for the possible eye color outcomes (using b for blue dash eyed and g for green dash eyed) of two children.
bb, bg, gb, gg
b. Assuming that the outcomes listed in part (a) were equally likely, find the probability of getting two green dash eyed children.
Four outcomes.
Of those, in one(gg), you get two green dash eyed children.
1/4 = 0.25
25% probability of getting two green dash eyed children.
c. Find the probability of getting exactly one blue dash eyed child and one green dash eyed child.
In two of those(bg and gb) you get one blue dash eyed child and one green dash eyed child.
2/4 = 0.5
50% probability of getting exactly one blue dash eyed child and one green dash eyed child.
Since she walks 4 miles per hour, you keep adding the miles onto the hours. 2 hours = 8. 3 hours = 12. The answer is 12 miles
