1. 81.72
2. 10.37
3. 81.72 + 10.37 = 92.09 81.72 - 10.37 = 71.35
4. 81.72 + 2(10.37)= 102.46 81.72 - 2(10.37) = 60.98
5. 81.72 + 3(10.37) = 112.83 81.72-3(10.37) = 50.61
6. no
7. It is not bell-shaped
8. P(>=90) = 15/50 = 3/10 = 30%; 2nd way??
9. 5 = 68, 12 = 72, 24 = 82, 35 = 89, 43 = 92
10. 80.6
11. no
12. The population mean includes all of the data values and the sample mean only includes the 5 data values.
This is a basic algebraic equation
And will be using PEMDAS to solve
P: Parentheses
E: exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
If you are unaware of PEMDAS this is the order at which you solve algebraic equation. So start from “P” and end with “S”
X= 2/3
2/3^3 Times 3 Divided by 2/9 + 9(2/3) - 7 - 6(2/3)
Now, personal I’d choose to convert fractions to decimals to simplify solving the equation. I doubt this is the only way to solve for the equation but I find this is the easiest
To convert a fraction to decimal you divide the numerator by the denominator.
So 2/3 is 0.666667
And
That means 2/9 is 0.222222
0.666667^3*3/0.222222+9(0.666667)-7-6(0.666667)
Making you answer roughly -0.999989
Hope this helps, but I’m not sure if this is completely right or not
Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula
here N(0) is initial amount of substance
t is time in days
Plug values in the formula
1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)
Answer:
The single transformation that maps shape A into shape B is 4 steps right and 3 steps down.
$0.81+$9.00=$9.81
Answer: $9.81
We know t<span>o find the total price, first find the amount of sales tax paid by multiplying the sales tax by the original price of the basket of watermelons.
</span><span>9%×$9=<span>?
</span></span>Percent means "out of one hundred," so <span><span><span><span>9% </span></span></span></span> is equivalent to <span>9/100 </span><span>which is also equal to 9 divided by 100.
9 divided by 100 is 0.09
</span>To find the amount of sales tax that must be paid, multiply <span><span>0.09 </span></span><span>by the original price.
So it would be 0.09*$9=$0.81
</span>
<span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
$0.81+$9.00=$9.81
</span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
