Answer:
$750 cost of the washer.
Step-by-step explanation:
3x+x=1,000
4x=1,000
x=1,000/4
x=$250 cost of the dryer.
3*250=$750 cost of the washer.
Proof:
750+250=1,000
1,000=1,000

Step-by-step explanation:
A polynomial expressed in standard form begins with the term with the largest exponent of the variable then lists the remaining terms in descending order of the exponents.
given
15
- 6x + 13x² - 1 ←
has largest exponent, hence
15
+ 13x² - 6x - 1 ← in standard form
Answer:
0.98046
Step-by-step explanation:
Given:
Here we are required to find
P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by
<em>z = (x - μ) / σ</em>
So 5.48 we have z = -2.714 and 5.82 we have z = 2.143
Therefore we have the area of interest on the normal distribution chart given by
:
P( -2,714 < z < 2.143)
= 1 - P(Z<-2.714) + P(Z > 2.143)
= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))
= 1 - 0.00336 + 1 - 0.98382
= 1 - 0.01954 = 0.98046
