Step-by-step explanation:
2 − 10n = 2 + 4n
What does n equal?
Answer:
0 =n
Step-by-step explanation:
2 − 10n = 2 + 4n
Add 10n to each side
2 − 10n+10n = 2 + 4n+ 10n
2 = 2 + 16n
Subtract 2 from each side
2-2 = 2+16n-2
0 = 16n
Divide each side by 16
0/16 = 16n/16
0 =n
Answer:
n= 0
Step-by-step explanation:
Step 1- Add 10n to both sides.
2-10n= 2+4n
+10n +10n
2= 2+14n
Step 2- Subtract 2 to both sides.
2= 2+14n
-2 -2
0= 14n
Step 3- Divide both sides by 14.
0/14= 14n/14
n= 0

Step-by-step explanation:
1/2 ^2 = 1/4

24/4 = 6
Please help me on questions 5-6. If you can, please do step by step please!! The subject on this is Uniform motion.
Answer:
5. 11.25 mi/hr
6. 24 hours
Step-by-step explanation:
5. The return trip at 9 mph took 5 hours. So the distance is 45 miles.
The total distance traveled is therefore 90 miles, and the total time is 3 + 5 = 8 hours.
The average speed is distance divided by time, or (90 mi) / (8 hr) = 11.25 mi/hr
6. If t is the time it takes driving there, then t−4 is the time it takes to drive back.
Distance = speed × time, so the forward trip is 25t miles, and the return trip is 30(t−4) miles. These distance are equal, so:
25t = 30(t−4)
25t = 30t − 120
120 = 5t
t = 24

Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, With a standard deviation of 2 feet if you took a sample of 64 trees, which of the following mean heights would be outside the 95% confidence interval
Answer:
Step-by-step explanation:
Given mean = 84,
Standard deviation = 2,
Sample 64,
95% confidence interval: z = 1.96
Applying empirical rule , means that 95% of data fall within two standard deviations.
ME = = 0.49
Rounding this to 0.5
CI = 83.5< mean < 84.5
Outside of this range= x ≤ 83.5 and ≥ 84.5
My test told me that 83.6 was right.

find the area of the shaded region
Answer:
38x² - 17x - 3
Step-by-step explanation:
The area of the shaded region is calculated as
area of outer rectangle - area of white rectangle, that is
(8x + 1)(5x - 3) - 2x(x - 1) ← expand (8x - 1)(5x - 3) using FOIL
= 40x² - 24x + 5x - 3 - 2x² + 2x ← collect like terms
= 40x² - 17x - 3
If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *
100
0
1
10
Answer:
10
Step-by-step explanation:
Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.
The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:
Coefficient of variation = mean / standard deviation
Coefficient of variation = 50 / 5
Coefficient of variation = 10

What is the slope of a line perpendicular to the line y = -1/4x − 1?
Answer:
4
Step-by-step explanation:
The slope of a line that is perpendicular is the negative inverse of the original. The slope of the given line is -1/4. This means that the slope of the perpendicular line will be 4.
The slope of a line perpendicular to the line; y = -1/4x -1 is:. 4
The line y = -1/4x − 1 takes the slope-intercept form of a straight line; y = mx + c.
In essence, the slope of the line y = -1/4x − 1 is;
m1 = -1/4Also, the slope of two perpendicular lines are related as follows;
m1m2 = -1The slope of the line perpendicular to line y = -1/4x − 1 is therefore;
m2 = -1/(-1/4)m2 = 4.In essence, the slope of a line perpendicular to the line; y = -1/4x -1 is:. 4.

A man has 1/3 of a kilogram of potatoes. He shares them equally amongst 5 people. How many kilograms does each person get? Input your answer as a fraction of a kilogram.
Answer:
1/15 Kilograms.
Step-by-step explanation:
Let each per get x kilogram
since there are 5 people
total potatoes got by 5 people = 5*x 5x kilograms
we know that total the man has was 1/3 kilogram , thus
5x must be equal to 1/3 kilogram
5x = 1/3
dividing both sides by 5
5x/5 = 1/(3*5)
x = 1/15
Thus, each person gets 1/15 Kilograms.
