C. because her distance from home is decreasing
Answer:
x = 0, 51
Step-by-step explanation:
<u>→First, you need to factor out the GCF (Greatest Common Factor), which is -0.03x, like so:</u>
-0.03x (x - 51) = 0
<u>→Remove the -0.03 by divide it by both sides:</u>
x(x - 51) = 0
<u>→Separate each, like so:</u>
x = 0
x - 51 = 0
<u>→Solve for x:</u>
x - 51 = 0
x = 51
<u>Your solutions are, 0 and 51.</u>
Answer:

Step-by-step explanation:
Hi there!
Let’s take a look at the question.
One can of paint contains 2 2/5. We can make it easier by transforming the fraction (2 2/5) to a decimal (2.4). Now you have 2.4. Next, it says “one dozen”. One dozen refers to 12 cans. You’ll want to multiply 2.4 with 12.
Your answer is 28.8, or 28 4/5.
Hope this helps!
probability that the persons IQ falls between 110 and 130 is 0.2286 .
<u>Step-by-step explanation:</u>
Step 1: Sketch the curve.
The probability that 110<X<130 is equal to the blue area under the curve.
Step 2:
Since μ=100 and σ=15 we have:
P ( 110 < X < 130 )=P ( 110−100 < X−μ < 130−100 )
⇒ P ( (110−100)/15< (X−μ)/σ<(130−100)/15)
Since Z = (x−μ)/σ , (110−100)/15 = 0.67 and (130−100)/15 = 2 we have:
P ( 110<X<130 ) = P ( 0.67<Z<2 )
Step 3: Use the standard normal table to conclude that:
P ( 0.67<Z<2 )=0.2286
Therefore, probability that the persons IQ falls between 110 and 130 is 0.2286 .
