Okay, so this is what I came to. I think that you might need to look through the placement of the problem again and your x's, but other than that, here it is!
Step 1: Simplify both sides of the equation.<span>425=<span><span>−<span>250<span>x2</span></span></span>+<span>6250x
</span></span></span>Step 2: Subtract -250x^2+6250x from both sides.<span><span>425−<span>(<span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>)</span></span>=<span><span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>−<span>(<span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>)</span></span></span><span><span><span><span>250<span>x2</span></span>−<span>6250x</span></span>+425</span>=0
</span>
Step 3: Use quadratic formula with a=250, b=-6250, c=425.<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a</span></span></span><span>x=<span><span><span>−<span>(<span>−6250</span>)</span></span>±<span>√<span><span><span>(<span>−6250</span>)</span>2</span>−<span><span>4<span>(250)</span></span><span>(425)</span></span></span></span></span><span>2<span>(250)</span></span></span></span><span>x=<span><span>6250±<span>√38637500</span></span>500</span></span><span><span>x=<span><span>252</span>+<span><span><span><span>110</span><span>√15455</span></span><span> or </span></span>x</span></span></span>=<span><span>252</span>+<span><span><span>−1</span>10</span><span>√15455
</span></span></span></span><u>
Answer:</u><span><span>x=<span><span>252</span>+<span><span><span><span>110</span><span>√15455</span></span><span> or </span></span>x</span></span></span>=<span><span>252</span>+<span><span><span>−1</span>10</span><span>√<span>15455</span></span></span></span></span>
Answer:
.758 or 163/215
Step-by-step explanation:
Conditional probablity formula:
(A|B)= (A∩B)/B
we have
.652/.86
this equals .758 or 163/215
Your answer is -1/2

Answer: $3.60 will be spent on the necklace.
Step-by-step explanation:
to solve this problem we have to divide the length of the necklace (30cm ) by the diameter of each bead (1.25) to obtain the number of beads needed for the necklace.
So, mathematically speaking:
30 cm / 1.25 cm =24 beads
Now, we have to multiply the number of beads by the cost of each one ($0.15).
24 x 0.15= $3.60
S000, $3.60 will be spent on the necklace.
