Answer:

a) bell-shaped.              

b) mean, median, and mode all equivalent.      

d) symmetric around the mean.        

g) most of the data fall within 3 standard deviations from the mean.

Step-by-step explanation:

We have to describe a normal distribution.

a. bell-shaped.

This is true a normal distribution is a bell shaped distribution.

b. mean, median, and mode all equivalent.

This is true for a normal distribution.

Mean = Mode = Median

c. Bimodal

The is not true about the normal distribution. A normal distribution is unimodal and the mode is equal to the mean of the distribution.

d. symmetric around the mean.

This is true. The normal distribution is centered around the mean

e. skewed to the right.

This is not a property of normal distribution.

f. models discrete random variables.

Normal distribution is a continuous distribution.

g. most of the data fall within 3 standard deviations from the mean.

This is true. According to Empirical rule, almost all the data lies within three standard deviation of mean.

h. uniform-shaped

This is not true. A normal distribution is bell shaped.

BigorU [14]

Answer:

X= (300 s + 200 b + 42 d )mg

Step-by-step explanation:

Amount of spinach=300 ml

Amount of berries =200 ml

amount of dressing = 42 ml

Vitamin C in one ml of spinach = s mg

Vitamin C in 300 ml of spinach = 300 s mg

Vitamin C in one ml of berries=b mg

Vitamin C in 200 ml of berries = 200 b mg

Vitamin C in one ml of dressing = d mg

Vitamin C in 42 ml of dressing = 42 d mg

Let total vitamin C be = x

Then

X= (300 s + 200 b + 42 d )mg

is the required expression
