Answer:
Step-by-step explanation:
- 4x - 5 = - 3*(2x + 10)
- 4x - 5 = - 6x - 30
- 4x + 6x = 5 - 30
- 10x = - 25
- x = - 2.5
Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
According to the condition, this equation has <u>two</u> solutions: -14/5 and 14/5.
Short explanation:
5|x|=14; ⇔ |x|=14/5; ⇒
PS. it's correct, if to substitute the values of 'x' into the condition/equation.
Answer:
Step-by-step explanation:
This is a binomial probability problem. There are only two outcomes. It is either a chosen person has immunity to a particular disease or he does not. The probability of success in this case, p is the probability that a chosen person has immunity to a particular disease. Thus
p = 0.6
The probability of failure, q is q = 1 - p
Thus, q = 1 - 0.6 = 0.4
Mean = np
Where n represents sample size. Thus,
Mean = 12 × 0.6 = 7.2
Because in the numerator and denominator of the fraction 1a/3a, you're able to simplify that and get 1/3. There is actually no solution to the problem you're asking. You're unable to find out what (a) equals.
