Check your answer:
(substitute the numbers to see if they will equal 2592: <span>2^5 is 32 and 9^2 is 81)</span><span>
Now subsitute it into A^B*C^D: 32*81 is 2592.</span>
Hello! So in order to solve this problem, it's best to start off making an equation. $18 + $.15x = $29.25
In this equation x represents the number of minutes she used. So now, we just have to solve for x.
First subtract $18 from both sides. Your new equation will be $.15x = $11.25. Then divide both sides by $.15 to get x by itself. $11.25/$.15 = 75.
So we can conclude that Bella spoke on the phone for 75 minutes this last month. Hope this helps!
Answer:
__63.81 inches__< μ <___65.87 inches__
Step-by-step explanation:
To calculate at 95% confidence interval, we need the Mean of the sample= 64.84
Sample size=32
Standard Deviation=2.9592
95% Confidence Interval: 64.84 ± 1.03
(63.81 inches to 65.87 inches)
"With 95% confidence the population mean is between 63.81 and 65.87, based on 32 samples."
<h2>♪Answer : </h2>
»f(x) = 7x² - 3x + 7
»f(2) = 7(2)² - 3(2) + 7
»f(2) = 7(4) - 6 + 7
»f(2) = 28 - 6 + 7
»f(2) = 29
»f(-1) = 7(-1)² - 3(-1) + 7
»f(-1) = 7(1) + 3 + 7
»f(-1) = 7 + 3 + 7
»f(-1) = 17
»f(0) = 7(0)² - 3(0) + 7
»f(0) = 7(0) - 0 + 7
»f(0) = 0 - 0 + 7
»f(0) = 7
so, f(2) + f(-1) + f(0) is
