1/8(p+24)=9<br> Distributive property

Grace [21]

Hey there!

1/8(p + 24) = 9

1/8(p) + 1/8(24) = 9

1/8p + 3 = 9

SUBTRACT 3 to BOTH SIDES

1/8p + 3 - 3 = 9 - 3

CANCEL out: 3 - 3 because it gives 0

KEEP: 9 - 3 because it help solve for the p-value.

NEW EQUATION: 1/8p = 9 - 3
SIMPLIFY IT!

1/8p = 6

MULTIPLY 8 to BOTH SIDES

1/8p * 8 = 6 * 8

CANCEL out: 1/8 * 8 because it gives 1

KEEP: 6 * 8 because it gives the p-value.

NEW EQUATION: p = 6 * 8

SIMPLIFY IT!

p = 48

Therefore, your answer is: p = 48

Good luck on your assignment & enjoy your day!

(Uniform) Suppose X follows a continuous uniform distribution from 4 to 11. (a) Write down the PDF of X. (b) Find P(X ≤ 7). Roun

love history [14]

Answer:

a) $f(x)= \frac{1}{11-4}= \frac{1}{7}, 4 \leq x \leq 11$

b) $P(X\leq 7) = F(7) = \frac{7-4}{11-4}= 0.4286$

c) $P(5 < X \leq 7)= F(7) -F(5) = \frac{7-4}{7} -\frac{5-4}{7}= 0.2857$

d) $P(X >5 | X \leq 7)$

And we can find this probability with this formula from the Bayes theorem:

$P(X >5 | X \leq 7)= \frac{P(X>5 \cap X \leq 7)}{P(X \leq 7)}= \frac{P(5$

Step-by-step explanation:

For this case we assume that the random variable X follows this distribution:

$X \sim Unif (a=4, b =11)$

Part a

The probability density function is given by the following expression:

$f(x) = \frac{1}{b-a} , a \leq x \leq b$

$f(x)= \frac{1}{11-4}= \frac{1}{7}, 4 \leq x \leq 11$

Part b

We want this probability:

$P(X \leq 7)$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a}= \frac{x-4}{11-4}$

And replacing we got:

$P(X\leq 7) = F(7) = \frac{7-4}{11-4}= 0.4286$

Part c

We want this probability:

$P(5 < X \leq 7)$

And we can use the CDF again and we have:

$P(5 < X \leq 7)= F(7) -F(5) = \frac{7-4}{7} -\frac{5-4}{7}= 0.2857$

Part d

We want this conditional probabilty:

$P(X >5 | X \leq 7)$

And we can find this probability with this formula from the Bayes theorem:

$P(X >5 | X \leq 7)= \frac{P(X>5 \cap X \leq 7)}{P(X \leq 7)}= \frac{P(5$
