Answer:

p = 4,8 ; r = 7,5 ; q = 4,5

Step-by-step explanation:

according to Thales's theorem, we have:

$\frac{3}{p}=\frac{5}{5+3}=\frac{5}{8}=> p= 3:\frac{5}{8}=4,8$

and: $\frac{5}{8}=\frac{r}{12}=> r=7,5\\\\\frac{5}{3}=\frac{7,5}{q}=> q=4,5$

Chris has a blue coat and a

Tju [1.3M]

Answer: P = 0.125 = 1/8

Step-by-step explanation:

We know that he has a blue coat and a black coat.

If he dresses at random, then the probability of getting the blue coat is equal to the quotient between the number of blue coats (1) and the total number of coats (2).

Then the probability is:

p = 1/2

We also know that he has blue pants and brown pants, the probability of getting at random the blue pants is calculated in the same way than above, then:

q = 1/2

And for the shirt he has a blue shirt and a red one, the probability of randomly selecting the blue one is calculated in the same way than above, then:

k = 1/2

Now, the joint probability (he selects all blue clothes) is equal to the product of the individual probabilities:

P = p*q*k = (1/2)*(1/2)*(1/2) = 1/8 = 0.125

What are two fractions equivalent to 12/14

Andrews [41]

Hey there!

12/14

• BOTH NUMBERS HAVE THE COMMON FACTOR OF 2, SO WE CAN DIVIDE BOTH THE NUMERATOR (TOP number) FROM THE DENOMINATOR (BOTTOM number)

= 12 ÷ 2 / 14 ÷ 2

= 6/7

= 18/21

Therefore, your answer is: 6/7 or 18/21

Good luck on your assignment and enjoy your day!

What is the equation of the line that passes through the point (-6, -8) and has a slope of 1/3

ivanzaharov [21]

Answer <u>(assuming it can be in point-slope form)</u>:

$y + 8 = \frac{1}{3} (x+6)$

Step-by-step explanation:

With the given information, we can use the point-slope formula, $y-y_1 = m (x-x_1)$ , to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ in the formula to do so.

The $m$ represents the slope, so substitute $\frac{1}{3}$ in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute -6 for $x_1$ and -8 for $y_1$ . This gives the following answer and equation (just make sure to convert the double negatives into positives:

$y-(-8) = \frac{1}{3} (x-(-6))\\y + 8 = \frac{1}{3} (x+6)$

Using radicals , write an equivalent expression for the expression 2 1/3

liq [111]

I'm assuming that the 1/3 is an exponent.

If so, then $2^{1/3} = \sqrt[3]{2}$

Which is the cube root of 2. Raising any value to the 1/3 power is the same as taking the cube root.
