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.
Answer:
Between (-0.675, 0.675)
Step-by-step explanation:
We know that a standard normal distribution curve is bell shaped unimodal , symmetrical about mean.
for thsi standard normal variate with notation z, we get mean =0 and std deviation = 1
For the middle shaded region, we find z such that the area between -z and z is 0.50 exactly half.
From standard normal distribution table, we get that z= ±0.675
Hence between z=-0.675 and z = 0.675 we get the middle region with area equal to exactly 1/2.
Between (-0.675, 0.675)
336.75/31 = 10.862
10.862 to the nearest tenth = 10.9
