-3(4-2y)=24
distribute the -3
-12+6y=24
add 12 to both sides
6y=36
divide 6 on both sides
y=6
Answer:
32 yd^2
Step-by-step explanation:
Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.
This prism has 6 surfaces:
- Front: 3 x 2.66 = 8
- Back: 3 x 2.66 = 8
- Top: 3 x 1.33 = 4
- Bottom: 3 x 1.33 = 4
- Side: 1.33 x 2.66 = 4
- Side: 1.33 x 2.66 = 4
Total SA: 8(2) + 4(4) = <u>32 yd^2</u>
Answer:
0.789
Step-by-step explanation:
First, find the expected value (the mean).
μ = ∑ x P(x)
μ = (0) (0.359) + (1) (0.436) + (2) (0.180) + (3) (0.025)
μ = 0.871
Next, find the variance.
σ² = ∑(x − μ)² P(x)
σ² = (0 − 0.871)² (0.359) + (1 − 0.871)² (0.436) + (2 − 0.871)² (0.180) + (3 − 0.871)² (0.025)
σ² = 0.622
Finally, find the standard deviation:
σ = √0.622
σ = 0.789
The original price is $60
7x+2 I'm not sure what solution it is though sorry
