The prime number is 17 if you look at a multiplication chart there is nothing that equals 17 on there right ?? Even if you divide you will have to find something close to 17 like 16

What is the equation of the circle whose center and radius are given.

muminat

Hello!

The equation for a circle is

$(x - h)^{2} + ( y - k)^{2} = r^{2}$

(h,k) is the center
r is the radius

Put in the values you know

$(x - 7)^{2} + ( y + 3)^{2} = 7^{2}$

Simplify

$(x - 7)^{2} + ( y + 3)^{2} = 49$

The equation is $(x - 7)^{2} + ( y + 3)^{2} = 49$

Hope this helps!

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.
