denis-greek [22]

Answer:

200 students attended the basketball game

Step-by-step explanation:

The complete question in the attached figure

Let

x ------> the number of students in fourth grade

s -----> the number of students at the basketball game

we know that

The number of students at the basketball game is four times the number of students in fourth grade

so

The linear expression is

s=4x -----> equation A

x=50\ students\ in\ fourth\ grade -----> equation B

substitute equation B in equation A and solve for y

s=4(50)

s=200\ students\ at\ the\ basketball\ game

therefore

200 students attended the basketball game

In a small town, 50% of single family homes have a front porch. 48 single family homes are randomly selected. Let X represent th
Reil [10]

Answer:

N(24, 3.46)

Step-by-step explanation:

We are given the following in the question:

Percentage of family homes having front poach = 50%

p = 50\% = 0.50

Sample size, n = 48

Normal approximation to the given distribution:

\mu = np = 48(0.50) = 24

\sigma = \sqrt{np(1-p)} = \sqrt{48(0.50)(1-0.50)} = 3.46

Thus, the distribution of single family homes is best approximated by the normal distribution N(24, 3.46) where mean is 24 and standard deviation is 3.46
