statuscvo [17]

Answer:

Step-by-step explanation:

Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be successful is

$\dfrac{6}{15}=\dfrac{2}{5}$

Jack made 7 out of 15 shots, so the probability that Jack's next shot will be successful is

$\dfrac{7}{15}$

The probability that they both make their next shot successfully is

$\dfrac{2}{5}\cdot \dfrac{7}{15}=\dfrac{14}{75}$

Tristen is building 3 trophies using Legos. He needs 324 total Legos. Tristen uses 220 Legos for the largest trophy and 135 Lego

Alexeev081 [22]

Answer: 166

Step-by-step explanation:

Number of trophies = 3

Total Legos required for all trophies = 324

Number of Legos for largest trophy(A) = 220

Number of Legos for smallest trophy(B) = 135

Number of Legos required for final trophy(C)

Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]

324 = 220 +135 + C

324 = 355 + C

324 - 355 = C

-31 = C

135 + 31 = 166
