Assume that 33.4% of people have sleepwalked. Assume that in a random sample of 1459 adults, 526 have sleepwalked.

lutik1710 [3]

Answer:

Step-by-step explanation:

Given that 33.4% of people have sleepwalked.

Sample size n =1459

Sample favourable persons = 526

Sample proportion p = $\frac{526}{1459} \\=0.361$

Sample proportion p is normal for large samples with mean = 0.334 and

std error = $\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.334(1-0.334)}{1459} } \\=0.0123$

a) P(526 or more of the 1459 adults have sleepwalked.)

$=P(p\geq 0.361)\\=P(Z\geq \frac{0.361-0.334}{0.0123} \\=P(Z\geq 2.20)\\=0.5-0.4861\\=0.0139$

b) Yes, because hardly 1.4% is the probability

c) 33.4 is very less compared to the average. Either sample should be improved representing the population or population mean should be increased accordingly.

How many solutions does the following equation have? 7(y + 3) = 5y + 8 answer:

vodomira [7]

Answer:

One Solution

Explanation:

7(y + 3) = 5y + 8

Simplify both sides of the equation

7(y + 3) = 5y + 8

(7)(y) + (7)(3) = 5y + 8 (Distribute)

7y + 21 = 5y + 8

Subtract 5y from both sides

7y + 21 − 5y = 5y + 8 − 5y

2y + 21 = 8

Subtract 21 from both sides

2y + 21 − 21 = 8 − 21

2y = −13

Divide both sides by 2

2y = −13

2y / 2 = -13 / 2

y = -13 / 2

-13 / 2 = -6.5

y = -13 / 2 or -6.5

Answer:

k = 3

Step-by-step explanation:

0 • 3 = 0

1 • 3 = 3

2 • 3 = 6

3 • 3 = 9

4 • 3 = 12

Notice the x value times 3 is the y value. Therefore, k is 3. Let me know if I got anything wrong. I hope this helps!
