Irene has a spinner with 5 sections, each with a different color. Irene spins the spinner many times, and records the results in the table.

Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10

Find the probability of spinning each color, based on the data. Explain how you calculated each probability.

Answers

Step-by-step explanation:

Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.

Total frequency = 16 + 11 + 9 + 14 + 10 = 60

Hence we have the following probabilities:

P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6

10% more than a number is 132
What is the number?

Answers

The number is 120.

1.1x = 132
x = 120

10% = 0.1 in decimal form. We’re looking for a number that when you take 10% of it & add it to itself (1.0) we get 132. Adding it to itself is why the first term is 1.1x

Latoya made $147 for 7 hours of work.
At the same rate, how much would she make for 9 hours of work?

help pls

Answers

Answer:

$189 in 9 hrs

Step-by-step explanation:

Division is one of the four fundamental arithmetic operations. The amount that Latoya will make by working 9 hours is $189.

What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Latoya made $147 for 7 hours of work. Therefore, we can write,

Money made in an hour = Total Amount / Number of hours

= $147 / 7 hours

= $21 per hour

Now, the amount that Latoya will make in 9 hours will be,

Amount for 9 hours of work = Money made in an hour × Number of hours

= $21 per hour × 9 hours

= $189

Hence, the amount that Latoya will make by working 9 hours is $189.

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?

A. $2.15; $2.83

B. $0.40; $5.13

C. $0.40; $1.08

D. $1.75; $2.15

Answers

Answer:

A. $2.15; $2.83

Step-by-step explanation:

2.83

c = 0.4. * 2.7 + 1.75

=> c = 2.83

4(2.7)+1.75

1.08+1.75=2.83

$2.83 is correct.

c=0.40(2.7)+1.75

c=1.08+1.75

c=2.83

Answer:

2.83 dollars

Step-by-step explanation:

Fixed charges made by the taxi company for a ride =

Additional charge for each mile travelled =

Hence equation for cost is given by

where m is thenumber of miles travelled.

To find out the charge for a 2.7 mile ride substitute m = 2.7

Total cost for 2.7 mile ride is 2.83 dollars
