Answer:
Step-by-step explanation:
10y2 - 17y + 12 = y + 16
10y2 - 17y + 12 - 16 = y
10y2 - 17y - 4 = y
10y2 -17y - y -4 = 0
10y2 -16y - 4 = 0
Now put formula
x = -b +- (square root) b2 - 4ac
2a
a = 10 b= -16 c= -4
y = -(-16) +- (square root) -16 - 4 (10) (-4)
2(10)
y = 16 +- (square root) -16 - 400
20
y = 16 +- (square root) -416
20
y = 16 +- 20.396
20
Now this +- is the plus minus thingy in which two answers come
The first we will do is +
16 + 20.396 16 - 20.396
20 20
= 1.8198 = -0.2198
Answer: total income is $27000
Step-by-step explanation:
Given that salary is $12,000 per year
5% commission on sales of $300,000=
5/100 × 300,000
=0.05 × 300,000
=$15,000
Total income = salary + commission
= $12,000 + $15,000 = $27000
Thus, total income is $27000
= -8/3 + 4/6
= -16/6 + 4/6
= -12/6
= -2 answer
Answer:
We use the Binomial Distribution where p =.84 then probability will be 0.931.
Step-by-step explanation:
P(X≥ 2) = P(X=2) + P (X=3)
= (³₂)(.84)^2(.16) + (³3)(.84)^3(.16)⁰
≅ 0.931
Hence 0.931 is the answer.
Answer:
20
Step-by-step explanation:
DE+DF=8x
DE+DF=32
8x=32
X=4
Since there is 5x in DE
5(4)=20
