Answer: If the first one is addition, which I'm pretty sure it is, the answer is
1 1/10
For the second problem, I'm pretty sure its subtraction, so the answer is 1/9.
Step-by-step explanation:
Answer:
P(x) = - 5(x + 2)²(x - 3)
Step-by-step explanation:
Given roots x = - 2 with multiplicity 2 and x = 3 , then the factors are
(x + 2)² and (x - 3)
P(x) is then the product of the factors, that is
P(x) = a(x + 2)²(x - 3) ← a is a multiplier
To find a substitute (2, 80) into P(x)
80 = a(2 + 2)²(2 - 3) = a(16)(- 1) = - 16a ( divide both sides by - 16 )
a = - 5
P(x) = - 5(x + 2)²(x - 3)
Answer:
Step-by-step explanation:
Let X be the no of adults whose feelings the state of morals is poor.
X has two outcomes and each trial is independent of the other
X is Bin with p = probability for success in each trial =40%=0.40
n=no of adults surveyed = 55
a) The probability that exactly 21 of those surveyed feel the state of morals is poor is
(b) The probability that no more than 22 of those surveyed feel that state of morals is poor is
=
(c) The probability that more than22 of those surveyed feel the state of morals is poor is
(d) The probability that 15 or 16 believe the state of morals is poor is
=
Answer:
Find a line which also has 3/4 as the slope or 3x - 4y in standard form.
Step-by-step explanation:
If the line is 3x - 4y = 1 then the line which is parallel will have the same coefficients of x and y. Parallel lines never cross and to ensure this have the same slope. The slope is a ratio which can be solved for in an equation using the coefficients of x and y. Here the slope is:
3x - 4y = 1
-4y = -3x + 1
y = 3/4x - 1/4.
Find a line which also has 3/4 as the slope or 3x - 4y in standard form.
T ∝ 1/v
<span>so, t = k/v or tv = k </span>
<span>Then, with t = 2.5 and v = 5 we have: </span>
<span>2.5 = k/5 </span>
<span>so, k = 12.5 </span>
<span>Therefore, t = 12.5/v or vt = 12.5 HOPE IT HELPED</span>
