Why do you think it’s important for students to learn about math
marissa [1.9K]

Answer:

Step-by-step explanation:

Math is in our everyday lives. We calculate and use math in our daily lives without knowing it. By learning math, we build on useful knowledge that will help us have a better future. For example, learning how to pay taxes acquire math. Grocery shopping needs you to find the cost of the product you’re buying. When we learn math, we gain knowledge and we can pass that knowledge to our future generations so more and more people can use it to find better jobs, make your life easier, and so much more. Therefore, that is why it is important for students to learn about math.

Malachy was thinking of a number. Malachy doubles it and gets an answer of 91.6. What was the original number?
zubka84 [21]

Answer:

45.8

Step-by-step explanation:

Say the number Malachy was thinking of is <em>x</em>.

Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:

2x = 91.6

To solve, we divide both sides by 2 and get x = 45.8, which is our answer.

The data below represents the number of hours an office assistant spends on the phone every week for 15 weeks.
Veronika [31]

A box plot contains two dots placed at the ends of the data for the mininum and the maximum value with a line placed over the median.

Let's put the numbers in your set in order from low to high:

5

6

7

8

9

9

9

10

12

14

17

17

18

19

19

The median is the middle number. We have 15 numbers so we select the 8th number - 7 from each end. In this set, 10 is the median.

Only one box plot has dots at 5 and 19 and a median of 10 - choice B. Thus, B is the proper box plot.
