UkoKoshka [18]

Answer:

3/26

Step-by-step explanation:

Probability of the first box to have the secret decoder ring is 18 out of 52:

  • 18/52= 9/26

Probability of the second box to have the ring is 17 out of 51, because one box with the ring already selected and not counted:

  • 17/51= 1/3

Probability that both of them have the secret decoder ring:

  • 9/26*1/3= 3/26

<u>So the answer is</u> 3/26

Answer:

"the sum of the cube of 6x and 2"

Step-by-step explanation:

We see that only the expression of 6x is being cubed, not the entire expression of (6x)³ + 2.

The first blank must apply to both these terms 6x and 2, so the word can't be cubed. Instead, because we're finding the sum of these two, the word should be "sum".

The second blank should apply to only the 6x because we've already described the relationship of 6x and 2. So, since we are cubing 6x, the word here should be "cube".

The final sentence should read:

"the sum of the cube of 6x and 2"

If geometry symbol represented as small triangle with three sides. abc geometry congruent symbol represented as two small horizo
n200080 [17]

The value of x in the congruent triangles abc and dec is 1

<h3>How to determine the value x?</h3>

The question implies that the triangles  abc and dec are congruent triangles.

The congruent sides are:

ab = de

bc = ce = 4

ac = cd = 5

The congruent side ab = de implies that:

4x - 1 = x + 2

Collect like terms

4x - x = 2 + 1

Evaluate the like terms

3x = 3

Divide through by 3

x = 1

Hence, the value of x is 1
