<span>This is a conversion problem. You are given one meter of yellow ribbon and 28 centimeters of blue ribbon. You are required to find for the number of centimeters of ribbon she needs. Note that there are 100 centimeters in one meter. So you have to convert the one meter of yellow ribbon into 100 centimeters of yellow ribbon. Then add the ribbons, 100 plus 28 equals 128 centimeters of ribbon. So Audrey needs 128 centimeters of ribbon all in all.</span>

Youre going to have to change meters to centimeters,I'm not sure what that is at the moment, but you can look up a conversion chart online.

After you do that just add the two numbers together.

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each,
Sav [38]

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops

A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66
Angelina_Jolie [31]

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
