X^2 + x^2 =32
2x^2=32
x^2=16
x=4
<span>The z for $38.60 = (38.60 - 45)/16 = -0.4
</span>
<span>The percent of area associated with $38.60 = P(z < -0.4) = 0.34458 =34.46%
</span>
<span>The z for $57.80 = (57.8 - 45)/16 = 0.8.
</span>
<span>The percent of area associated with $57.80 = P(z < 0.8) = 0.78814 = 78.81%
</span><span>the percent of his expenses between $38.60 and $57.80 is (78.81 - 34.46) = 44.35%</span>
To find the area of a triangle, use the formula that is A= 1/2(base x height)
Answer:
2 x = 5 2x=5 2x=5. 2x=5. 2x=5. 2x=5. 1. Divide both sides by 2 2 2. x = 5 2 x=\frac{5}{2} x=25. Done. Decimal Form: 2.5. Check Answer ▽. x=5/2.
Step-by-step explanation:
The equation is false because the real answer is z5/4. The variable doesn't just disappear.
