Answer:
Step-by-step explanation:
4x − 1 = 19
solving for x, x = 5
2x − 4 = 10
x=7
2x + 2y = 48
x=24-7
y=24-x
5x + 2y = 90
x=18-2y/5
y=45-5x/2
all the situations I could find hope this helps for each equation.
Answer:
The answer is C
Step-by-step explanation:
Answer:
x = 9 and x=-16
Step-by-step explanation:
The equation is
x2 + 7x = 144
Solving that using the formula
x= 9 and x=-16
Given the information, we shall proceed as follows:
The given problem is a binomial problem.
n=10 and p=0.48
thus, the probability that the number who consider themselves baseball fans is:
a] exactly five
P(x=5)=10C5(0.48)^5(0.52)^5=0.244
b] at least 6
P(x>=6)=1-P(x<8)
=P(6)+P(7)+P(8)+P(9)+P(10)
=10C6(0.48)^6(0.52)^4+10C7(0.48)^7(0.52)^3+10C8(0.48)^8(0.52)^2+10C9(0.48)^9(0.52)^1+10C10(0.48)^10
=0.1878+0.0991+0.0343+0.0070+0.0007
=0.3289
The answer: 0.3289
c] Less than 6
P(x<6)=1-P(x>=6)
=1-0.3289
=0.6711

SORRY GOOD LORD BUTTTTTTT MAYBE C
