I disagree because she can use a pencil and paper or she can do mental math
To find the probability of choosing a red card we need to add both the cards so we have a total amount of cards.
17 + 9 = 26
Since, the question is asking the probability of choosing a RED card then the probability is a 17/26 chance. The answer choices are written as ratios. The ratio that is the same to 17/26 is [ D. 17:26 ]
Best of Luck!
Answer:
First diagonal: 7.874
Second diagonal: 8.3666
Step-by-step explanation:
We use the Pythagorean Theorem to find these.
First diagonal = 5²+6²=c²
25+36=c²
61=c²
√61=c
c=7.874
Then we use that to find the second diagonal.
7.874²+3²=c²
61+9=c²
70=c²
√70=c
c=8.3666
