Answer:
a) a combination
b) The probability = 1 ÷ [ Number of ways to select the four dancers ]
Step-by-step explanation:
a) Here it is only required to calculate the number of ways to select the four dancers and the order of the dancers is not required i.e not important for us.
Hence, we will use a combination to select 4 out of 22 dancers
i.e ²²C₄
b) Since the dancers selected are 4 predetermined individuals
therefore,
number of ways to select selecting dancers Laura, Matthew, Lakiesha, and Santos will be '1'
Hence,
The probability = 1 ÷ [ Number of ways to select the four dancers ]
= 1 ÷ ²²C₄
Answer: 150 students walk to school
Step-by-step explanation: 75%=0.75
200 multiplied by 0.75
200×0.75=150 students
Or
75%=3/4
3/4 of the children walk to school
3/4×200=3/4×200/1=150
Answer:
2.862*10^5
Step-by-step explanation:
First, move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 286200 you will get 2.862.
next, since you moved the decimal place to the left 5 times, the xoonent would be a positive 5.
Therefore, the answer is 2.862*10^5
B is the correct answer distributive property
B = 655.096 + 9.563W + 1.85H - 4.676A W = 55 A = 70 H = 172 now we sub B = 655.096 + 9.563(55) + 1.85(172) - 4.676(70) B = 655.096 + 525.965 + 318.2 - 327.32 B = 1499.261 - 327.32 B = 1171.941 1171.941 - 1000 = 171.941 rounds to 172 answer is B. 1000 calories is not sufficient, it is 172 calories short
