Step-by-step explanation:
Answer:
12x⁹ + 15x⁸ - 8x⁶ - 10x⁵
Step-by-step explanation:
<u>This is incomplete and should be: </u>
- x⁴ • (3x³ - 2) • (4x² + 5x)
<u>Solution with steps</u>:
- x⁴ • (3x³ - 2) • (4x² + 5x) =
- x⁵• (3x³ - 2) • (4x + 5) =
- x⁵• (12x⁴ + 15x³ - 8x - 10) =
- 12x⁹ + 15x⁸ - 8x⁶ - 10x⁵
Answer: Each shirt costs $1.25, and each hat costs $2.5.
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given,
3x+3y=11.25 (i)
4x+2y=10 (ii)
Multiply 4 to equation (i)
12x+12y=45 (iii)
12x+6y= 30 (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.
Answer:
as p decreases, sigma decreases.
Step-by-step explanation:
Given that 35%are hispanic. For a sample of 17 members
n = 17
p = 0.35
and the number of Hispanics on the committee would have the binomial distribution
a) Mean of X = E(x) = 
b) Std dev X = 
c) Here n =17 and p =0.1
d) When p = 0.01
Thus we find that as p decreases, sigma decreases.
