Answer:
9 gram/cm³
Step-by-step explanation:
Volume of a square (L³) = 2³ = 8cm³
Volume of a square (L³) = 2³ = 8cm³
But Density = mass/volume
But Density = Mass/Volume
Density = 72grams/8cm³
Density = 9grams/cm³
Answer:
Option A 0.312 is right
Step-by-step explanation:
Given that iN Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57% of the sales are from store B. 2.4% of the DVD players sold at store A are defective while 4.0% of the DVD players sold at store B are defective.
Prob for any random item form store to be defective = Prob from A and defective +Prob from B and defective
=
Prob it came from A and defective = 0.
If Kate receives one of these DVD players as a gift and finds that it is defective, what is the probability that it came from store A
=
<span>w = 0.4444444444x
becase you gotta divide each side by 9 so if you simplify it its
</span><span>w = 0.4444444444x</span>
Answer:
3/20
Step-by-step explanation:
Answer:
x = -2, y = -3
Step-by-step explanation:
Multiply eqn1 by the LCM of 1 and 6 i.e coefficients of x
We get:
<u> </u><u> </u> 6x - 54y = 150 (eqn1)
<u>6x - 5y = 3</u> (eqn2)
<u> - 49y = 147</u>
y = <u>147</u>
-49
y = -3
Substitute y in eqn2
6x - 5(-3) = 3
6x + 15 = 3
6x = -12
x = -2
