On Monday, a museum had 350 visitors. On Tuesday, it had 550 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would
have to visit the museum on Wednesday to have the same estimated percent change between
Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Which of these is the best estimate for the percent change in the number of visitors to the museum?
OA. 75% decrease
OB: 100% decrease
OC. 25% increase
OD. 50% increase​

50% increase  and approximately 825 people on Wednesday

Step-by-step explanation:

the amount of change = 550 - 350 = 200

Therefore, the percent of change is 200/350 =  .5714 = 57.1%

Best estimate is 50%

Using 50% as the percent of change, then 1.50(550) = 825 people is the estimated number of people on Wednesday.

50% increase

Step-by-step explanation:

the correct answer is 5 6 and 7

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
