Mrac [35]

Answer: Option A

P(B and V)=10%

Step-by-step explanation:

To solve this poroblema we use the formula of combinations:

$nCr =\frac{n!}{r!(n-r)!}$

Where n is the number of objects that can be chosen and you choose r from them.

There are 5 colors of shirts.

The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:

$5C2$

$5C2=\frac{5!}{2!(5-2)!}$

$5C2=10$

The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

$2C2 = 1$

Then the probability is:

$P(B\ and\ V)=\frac{2C2}{5C2}\\\\P(B\ and\ V)=\frac{1}{10}\\\\P(B\ and\ V)=0.1=10\%$

Triangle ABC is dilated to create triangle A'B'C' using point O as the center of dilation. What is the scale factor of the dilat

Fynjy0 [20]

Answer:

The scale factor is 4

Step-by-step explanation:

This question requires an attachment; I'll answer this question using the attached figure

From the attachment

Length OA = 3 units

Length OA' = 3 units + 9 units

Length OA' = 12 units

Scale Factor is calculated as follows;

$Scale\ Factor = \frac{New\ Side}{Original\ Side}$

Given that the original shape is ABC, the original side will be OA

Hence, Original Side = 3 units

New Side = OA' = 12 units

The formula becomes

$Scale\ Factor = \frac{12\ units}{3\ units}$

$Scale\ Factor = 4$

Hence, the scale factor is 4

Hello,

The answer to this question would be B. A right scalene triangle is a "Triangle" that has a right angle into it.C would not be the answer b/c is has an obtuse angle,and So does D. So the answer is not D,So dont pick D b/c I see that you have it marked.

Hope this helps

If $\frac{9u-11}{2} = \frac{19u+11}{3}$, what is the value of $u$? Ps i need the answer

klio [65]

I believe you are referring to this equation: (9u-11)/2 = (19u +11)/3. To solve this step-by-step, first, multiply each side by 6 which is the least common denominator of 2 and 3. This then results to: 27u - 33 = 38u + 22. Second, combine like terms on one side such that: 11u = -55. Finally, the value for u is calculated to be -5.

What is the correct answer???

lapo4ka [179]

Answer:

Step-by-step explanation:

The given equation passes through the origin:

$y-0 = \frac{1}{4} (x-0) + 4$

The segment passes through the point (-2,6)

So the equation will become $(y-6) = \frac{1}{4} (x+2) +4$
