Answer:
t(x) = 948(0.955)^x
Step-by-step explanation:
I had this for a warm up
I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:
-c^2-4c+21
From here, we’ll factor out a -1 so that we have:
-(c^2+4c-21)
Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:
(c + (-3))(c + 7)
(c - 3)(c + 7)
And adding back on the negative from a few steps earlier:
-(c - 3)(c + 7)
7.03 can be converted to 7 3/100.
.03 is the equivalent to 3 hundredths, we know this because it in the hundredths place.
The answer to the equation is approximately 536.91
Answer:
A
Step-by-step explanation:
We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.
<em>There are 50 in total, and 8 of them are red, so:</em>
P(red) = 
<em>Now we multiply this with 500 to get:</em>
The correct answer is A.
