BaLLatris [955]

Answer:

PQ = 3.2

Step-by-step explanation:

$QR =\frac{1}{3} PR$

$QR =\frac{1}{3} \times 4.8$

$QR =1.6$

PQ = PR - QR

PQ = 4.8 - 1.6

PQ = 3.2

Answer:

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5\}$

$n(S) = 5$

Required

$P(x > 1\ and\ x < 2)$

$P(x > 1\ and\ x < 2)$ is calculated as:

$P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)$

Since it is a probability with replacement, we have:

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

For x > 1, we have:

$x > 1 = \{2,3,4,5\}\\$

$n(x > 1) = 4$

For x < 2, we have:

$x < 2 = \{1\}$

$n(x < 2) = 1$

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

becomes

$P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}$

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

If the distance between the points<br>(4.p) and (1,0) is 5, then p=? *

Hatshy [7]

Answer:

p=4

Step-by-step explanation:

distance b/n points is given by formula

$5= \sqrt{(1 - 4{}) {}^{2} + (0 - p {}^) {}^{2} }$

$25 = {9 + p {}^{2} }$

$p {}^{2} = 25 - 9$

$p = 4$
