Answer:
I predict he will select the blue marble 8 times
Step-by-step explanation:
In total there are 60 marbles so if they select a marble 30 times, that is half of 30. I just took half of the blue marbles and that would be the theoretical probability
Can I have brainliest plz
Answer:
1000+150=1150+150=1300+150=1450+150=1600+150=1750+150=1900
3000+100=3100+100=3200+100=3300+100=3400+100=3500+100=3600
1900=2050+300=2350=2650=2950+150=3100+300=3400+600=4000
3600=3700+200=3900=4100=4300+100=4400+200=4600+400=5000
4000=4600=5200=5800+300=6100=6400+150=6550=6700=6850=7000
5000=5400=5800=6200+200=6400=6600+100=6700=6800=6900=7000

To answer this question, you need to determine the altitude difference and speed difference of plane B and plane A.
The initial altitude difference should be: 5000 feet- 3586 feet= 1414 feet.
The speed difference should be: 30.25 ft/s - 55.5 ft/s= - 25.25ft/s
After that, you can determine how long will pass before the plane in the same altitude.The calculation would be:
Final altitude difference= Initial altitude difference + speed difference*time
0 ft= 1414 ft + (-25.25ft/s * time)
25.25 time= 1414s
time= 56 second
To determine the altitude you just need to sample either plane A or plane B. Let's use plane B for easier initial altitude. The calculation would be:
Final altitude= initial altitude + speed*time = 5000ft + 30.25ft/s *56s= 6694ft
Complementary angles add to 90 degrees.
3x+5+2x-15=90
5x-10=90
5x=100
x=20 <=======
Plug in the value of x
3(20)+5
60+5
65= angle A <========
2(20)-15
40-15
25= angle B <========
Whenever it says divide just flip the fraction and change it to multiply
