hello :
B. (x − 4)(x + 9)
calculate : (x − 4)(x + 9)= x²+9x-4x-36 = x²+5x-36
<span>The
number of 2.00-L bottles could be filled from a 24-can case of cola
if in the United States a typical can holds 355 mL can be solved by:</span>
34 (355 mL) = 12070 mL
12070 ml( 1 L / 1000 mL ) = 12.07 L
Number of 2 -L bottles it can fill = 12.07 L / 2 L = 6

Answer:
Ok, this is quite a bit more work than I am used to but I will try!
Step-by-step explanation:
Ok, seeing we have no hidden value for <em>x </em>I presume that we are using it as a coordinate plane listing location. Now that we have that settled, that would mean for the first bit on "A" is y= -4x is starting at x=0 on the number line and we are moving it back 4 spaces. Next bit for "A" is y=2(-x+1) seeing that it is right beside it means it is multiplication and we will be using PEMDAS for this one so we can get the best results. We will start with taking -x which automatically makes it -1x because there is no value infront of it and adding 1 because of +1, you can't have -0 you know! Meaning this value is y=0 because anything times zero is, say it with me! ZEEERROOOO! Now for part B, we moved back to "x" but for both parts... hmm.... well, let's start! -4x=2(-x+1), practically our last question but with multiple "x's". Using same logic, answer is -4x=0, meaning the value of "x" is 0. Turns out last questions "y" variable was an actual variable! Not a piece on the coordinate plane, silly me! Next answer is 0 and after that -4x=2(-x+1) we got the same logic as our last question, almost exact actually! There fore -4x=0! Hope this helped and have a good day! :D
Answer:
A confidence interval for a mean should be constructed to estimate the variable of interest.
Step-by-step explanation:
The confidence interval for a mean uses the sample mean to estimate the true population mean. Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean. In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.
