spin [16.1K]3 years ago
4 0

Answer:

roughly 20 times

Step-by-step explanation:

2/6 = 1/3 is the probability he will roll a 3 or a 6

1/3 * 60 = 20.

It's not exact because you can't predict exactly what will happen, so it's roughly 20 times.

Solve i + j + t (3i - j) = -i + s (j)<br> In the context of Vector Equations of a Line
Oksana_A [137]

Answer:

r = i + j + (-2/3)(3i - j)

Step-by-step explanation:

Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant

if a = i + j ; b = t(3i - j) and r = -i +s(j)

for this to be true all the vector components must be equal

summing i 's

i + 3ti  = -i; then t = -2/3

j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3

so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j

PLZ HELP ASAP WILL MARK BRAINLIEST:
Andreas93 [3]

Answer:

Choice 2.

Step-by-step explanation:

Multiply every number by two to get to the next points. This new triangle cannot be congruent to the first one because congruent means it is exactly the same. The new triangle is similar because its measurements are different.

Hope this helps!

Answer:

2/(3a^(1/3))

Step-by-step explanation:

The derivative of g(x) = 2/(3x^(1/3))

you get this by bringing the exponent of g(x) down and the new exponent is (2/3) - 1 .

Then replace x with a
