Convert to Scientific Notation
8.6 × 10^8
₋₋₋₋₋₋₋₋₋₋₋₋
3.2 × 10^3
Convert the fraction to a decimal by dividing the numerator by the denominator.
268750
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the e xponent will be positive.
2.6875 × 10^5

Answer:
Input is the number in the first column of the table. This is the number that you start with to follow the rule if the rule is given. You would also use this number to figure out what the rule is if it is not given.
Step-by-step explanation:
An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (\begin{align*}x\end{align*}-value) by 3 to find each output number (\begin{align*}y\end{align*}-value).

7 1/5 times 49 7/5 equivalent to 49
Step-by-step explanation:
7 1/5 × 49 7/5 = 49
convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators
36 + 252 = 288
288/5 = 245/5
57 3/5 = 49
These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?

You measure 41 textbooks' weights, and find they have a mean weight of 30 ounces. Assume the population standard deviation is 12.3 ounces. Based on this, construct a 93% confidence interval for the true population mean textbook weight. Round z-values to 2 decimal places; round t-values to 3 decimal places. Round final answers to 2 decimal places.
Answer:
The 93% confidence interval is [tex] 26.52 < \mu < 33.48 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 41
The mean is [tex]\= x = 30[/tex]
The standard deviation is [tex]\sigma = 12.3[/tex]
From the question we are told the confidence level is 93% , hence the level of significance is
[tex]\alpha = (100 - 93 ) \%[/tex]
=> [tex]\alpha = 0.07[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.81[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.812 * \frac{12.3}{\sqrt{41} }[/tex]
=> [tex]E = 3.48 [/tex]
Generally 93% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex] 30 -3.48 < \mu < 30 + 3.48 [/tex]
=> [tex] 26.52 < \mu < 33.48 [/tex]

Answer:
d=90 e=27 f=153
Step-by-step explanation:
since 90 is one half of 180 if d was any bigger or smaller the the information given would be incorrect.
e is 27 since vertical angles
f is 157 since a line is equal to 180 and since e is 27 you subtract 27 from 180

slope = -2
y intercept = 6
=====================================================
Explanation:
Let's find the slope
m = (y2-y1)/(x2-x1)
m = (2-4)/(2-1)
m = -2/1
m = -2
The slope is -2
Let's use this slope along with the first point to get the y intercept
y = mx+b
y = -2x+b ... plug in the slope we found earlier
4 = -2*1+b ... plug in the coordinates of the point (1,4)
4 = -2+b
4+2 = -2+b+2 .... adding 2 to both sides
6 = b
b = 6
The y intercept is 6
The equation y = mx+b turns into y = -2x+6 since m = -2 is the slope and b = 6 is the y intercept.

Jackson wants to buy a new car and needs a car loan. The cost of the car is $28,326. The car loan interest rate is 0.9% per year
How much money will Jackson pay in interest for one month?
А
$21.24
B
$212.45
С
$254.93
D
$2,124.45
Given :
Jackson wants to buy a new car and needs a car loan.
The cost of the car is $28,326. The car loan interest rate is 0.9% per year.
To Find :
How much money will Jackson pay in interest for one month.
Solution :
Interest on the loan is given by :
[tex]I=28326\times 0.009\\\\I=\$254.934[/tex]
Amount Jackson will pay in interest for each month is :
[tex]A = \dfrac{254.934}{12}\\\\A = \$21.24[/tex]
Therefore, Jackson will pay $21.24 dollar interest per month.
Hence, this is the required solution.
