Answer:
This is the even numbers out of 100. So Do every other one so in you case 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30.And all them problem you do add up to 15 total of what you completed( why they said there will only be 15 problems AKA the ones you solve)
Step-by-step explanation:

the answer to 2/4%8/10 is 0.05
Answer:
1. 0.9648
2. 0.602
3. 0.0352
4. 0.398
Step-by-step explanation:
We solve using binomial probability
n = 15
P = 20% = 0.2
1. At least 1 is tight
= P(X>=1)
P(X>=1) = 1-p(X= 0)
= P(x=0)
= 15C0(0.20)⁰(1-0.20)^15-0
= 15C0(0.20)⁰(80)¹⁵
= 0.0352
P(x>=1) = 1-0.0352
= 0.9648
2.
More than 2 ties tight
P(X>2)
P(X>2) = 1-p(X<=2)
p(X<=2) = p(x=0) + p(x=1) + p(x=2)
= p(x=0) = 0.0352
p(x=1) = 15C1(0.20)¹(0.80)¹⁴
= 0.1314
p(x=2) = 15C2(0.20)²(0.80)¹³
= 0.2309
P(x>2) = 1-(0.0352+0.1314+0.2309)
= 0.602
3.
No ties is tight
P(X = 0)
= 15C0(0.20)⁰(0.80)¹⁵
= 0.0352
4.
At least 3 are not tight
This says that at most we have 3 to be too tight
= p(X<=2) = p(x=0) + p(x=1) + p(x=2)
= 0.0352+0.1319+0.2309
= 0.398
Answer:
B
Step-by-step explanation:
-(x^2+4x-21)
If you were to factor this, it would be,
-(x+7)(x-3)
