The line graph is used to compare the trends of a variable over a period of time.

Therefore, the <span>graphical representation that would best display the number of points a home team and a visitor’s team scored in each game this season is the double bar graph.</span>

According to the data, the mean quantitative score on a standardized test for female college-bound high school seniors was 500.
Sveta_85 [38]

Answer:

6.68% of the female college-bound high school seniors had scores above 575.  

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 50

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(scores above 575)

P(x > 575)

P( x > 575) = P( z > \displaystyle\frac{575 - 500}{50}) = P(z > 1.5)

= 1 - P(z \leq 1.5)

Calculation the value from standard normal z table, we have,  

P(x > 575) = 1 - 0.9332= 0.0668 = 6.68\%

6.68% of the female college-bound high school seniors had scores above 575.

A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Anon25 [30]

Answer:

192

Step-by-step explanation:

The area of the cereal box = 8 x 3 x 10 = 240

Therefore, if 100% of the box is filled with

cereal, the amount of cereal in the box

will be 240.

now, 80% is x

80/100 = x/240

cross multiplying,

100x = 80×240

100x = 19 200

dividing both sides by 100

x = 192
