Answer: Bradley would expect 94 times to get a blue or green gumball.
Step-by-step explanation:
Since we have given that
Number of blue gumballs = 15
Number of yellow gumballs = 12
Number of green gumballs = 2
Number of purple gumballs = 16
Total number of all gumballs = 45
Probability of getting either a blue gumball or green gumball be
![\frac{15}{45}+\frac{2}{45}=\frac{17}{45}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B45%7D%2B%5Cfrac%7B2%7D%7B45%7D%3D%5Cfrac%7B17%7D%7B45%7D)
So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :
![\frac{17}{45}\times 250=94.4](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B45%7D%5Ctimes%20250%3D94.4)
Since we know that it must be less than 94.4.
So, the nearest smallest integer will be 94 times .
Hence, Bradley would expect 94 times to get a blue or green gumball.
Use the Pythagorean theorem.
(Dish)^2=120^2+90^2
Answer:
7
Step-by-step explanation:
→ Find the scale factor
30 ÷ 25 = 1.2
→ Multiply answer by 20
20 × 1.2 = 24
→ Equate equation to 24
4x - 4 = 24
→ Add 4 to both sides
4x = 28
→ Divide both sides by 4
x = 7
