The numbers are best written as,
(1.2 x 10⁻²)(3.65 x 10⁸)
If we multiply the bases of the scientific notations, we get an answer of 4.38. There exists a rule which states that for exponents of the same number which are multiplied, we add up the exponents. Thus, our final answer would be,
4.38 x 10⁶
Answer: a child ticket costs $14.50
Step-by-step explanation:
x=children ticket
x+4.50=adult ticket
3 children and 2 adult
3x+2(x+4.50)=81.50
3x+2x+9.00=81.50
5x+9.00=81.50
5x+9.00-9.00=81.50-9.00
5x=72.50
5x/5=72.50/5
x=14.50
Answer: 31.7
Step-by-step explanation:
Felix mean= 9.4
Felix median= 7
Tyler's mean= 54
Tyler's median = 66
The mean of combined data will be the mean of Felix and the mean of Tyler. This will be:
= (9.4 + 54)/2
= 63.4/2
= 31.7
Avg of 7 numbers = 9
Total of 7 numbers will be = 9 * 7 = 63
Avg of 3 of them is = 5
Total of those 3 will be = 3 * 5 = 15
Therefore the total of other 4 = 63 - 15 = 48
Ergo , avg of them = 48 / 4 = 12
Answer is 12
hope this helps!
Answer: the slope intercept form for this situation is y = 0.07x + 39
Step-by-step explanation:
The cell phone package charges $39 even if 0 minutes are used during the month. This means that the package has a constant charge of $39.
Each additional minute of talk time adds $0.07. Assuming x additional minutes of talk time is made, the total cost of x additional minutes of talk time would be
0.07x + 39
Let y represent the total cost of x additional minutes, then
y = 0.07x + 39
The equation for the slope intercept form is expressed as
y = mx + c
Where
m = slope
c = intercept.
Comparing with our equation,
The slope is 0.07 and the intercept is 39
