1 to the exponent of any number is equal 1
Answer:
1¹³ and 1¹⁵
Step-by-step explanation:
The answer does not change however we add or reduce the exponents. This is the uniqueness of the integer 1. When the others are tried, 6¹=6 and 9¹=9
7⁸=5764801 and 8⁷=2097152
9²=81 and 4³=64
Therefore the integer 1 is the only number that is not affected by exponents.

Name each regular polygon. Find the measure the indicated angles
Answers
i. 180°
ii. 60°
iii. 360°
iv. 120°
EXPLANATION
The given regular polygon has 3 sides.
Since all the three sides are equal, it is called an equilateral triangle.
The sum of interior angles of an equilateral triangle is 180°
One interior angle is 60° because all the three angles are equal.
The sum of exterior angles is 360°
One exterior angle is 120° because all the three exterior angles are equal.
Two lines intersecting at a right angle ?
Answers
Answer:
are perpendicular
Yes, it is perpendicular
Parallel is when you have two lines that do not intersect
A ray is a line that has one definite starting point and no obvious end point. (Stars with a point and "ends" with an arrow, meaning that it goes on "forever")
A line is just one specific line
When you have perpendicular, that is when two lines cross each other forming a right angle as you may now know

Answers
Answer:
6 feet 4 inches
Step-by-step explanation:
Step-by-step explanation:
3 FEET 2 INCHES These are not the same! Do not multiply
Each foot is 12 inches. So 3 times 12 (3 feet) is 36, add the extra 2 inches for 38 inches.
38 plus 32 equals 70 total inches. NOw we put it back into feet.
70 divided by 12 is 5, remainder 10.

A set of data has a normal distribution with a mean of 49 and a standard deviation of 8. Find the percent of data within the following interval. from 33 to 65.
Answers
Answer:
95 percent
Step-by-step explanation:
The empirical rule states that approximately 95% of observations will fall within 2 standard deviations of the mean if the population is approximately symmetrical(normal) in distribution.
The interval from 33 to 65 falls within 2 standard deviations of the mean;
49-2(8) = 33
49+2(8) = 65
Thus, 95 percent of data will fall within the interval from 33 to 65

Find the mean absolute deviation. Round to the tenth
Answers
Answer:
1) 1.8 round to tenths
Step-by-step explanation:
To find the mean absolute deviation we follow these steps:
Find the mean value by adding all data values and dividing by number of data valuesFind the absolute value of the difference between each data value and the mean: | data value – mean. | Divide the sum of the absolute values of the differences by the number of data values1) 4,5,10,8,4,8,7,6
step 1
4+5+10+8+4+8+7+6 / 8 = 6.5
Mean (μ): 6.5
step 2
|4-6.5| + |5-6.5| + |10-6.5| + |8-6.5| + |4-6.5| + |8-6.5| +|7-6.5| + |6-6.5| = 14
step 3
14 / 8 = 1.75
Repeat these steps for other parts.
David’s garden produced six bushels of zucchini, three bushels of beans, seven bushels of corn, and four bushels of beets. In the table below, write the fraction (in simplest form) and the percent of David’s total crop that each vegetable represents.
Answers
Answer:
Step-by-step explanation:
Zucchini = 'z' = 6
Beans = 'b' = 3
Corn = 'c' = 7
beets = 't' = 4
Total produce = 20 bushels of veggies.
z = 6/20 = 3/10 % = 3/10*100 = 30%
b = 3/20 % = 3/20 * 100 = 15%
c = 7/20 % = 7/20 *100 = 35%
t = 4/20 = 1/5 % = 1/5 * 100 = 20%
Total 100%

Frederick headed for Lutzen at 3 kph. Later he increased his speed to 4 kph. If it was 52 kilometers to Lutzen and the total time of travel was 15 hours, how long did he travel at 3 kph?
Answers
Since distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hoursSince distance is equal to rate times time:
Let x= the time traveled at 3 km/h
Let y= the time traveled at 4 km/h
We can say that
3x+4y=52
Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.
Likewise, we can see that:
x+y=15
Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.
Now, I'll solve by substitution.
x=-y+15
Substitute that into the other equation.
3(-y+15) + 4y = 52
Distribute
-3y + 45 + 4y = 52
Combine like terms
y + 45 = 52
Minus 45 from both sides
y = 7
So Fredrick traveled at 4 km/h for 7 hours.
Now, to find the other value, substitute the value of y into one of the original equations.
x + 7 = 15
Minus 7
x = 8
So
Time traveled at 4 km/h = 7 hours
Time traveled at 3 km/h = 8 hours

Select all the expressions equivalent to 3.1⁴.
Answers
Answer:
A, B, DStep-by-step explanation:
[tex]3.1^4=(3.1)(3.1)(3.1)(3.1)\to\boxed{A}\\\\3.1^4=[(3.1)(3.1)](3.1)(3.1)=(9.61)(3.1)(3.1)\to\boxed{B}\\\\3.1^4=[(3.1)(3.1)][(3.1)(3.1)]=(9.61)(9.61)\to\boxed{D}[/tex]
Equivalent expressions to 3.1⁴ involve raising 3.1 to the power of 4. This means 3.1 is multiplied by itself four times, not three times (which would be cubing). The equivalent expression would result from multiplying 3.1 by itself four times.
Explanation:The equivalent expressions to 3.1⁴ involve the operation of raising a number to a power. In this case following the number 3.1, the exponent of 4 means that 3.1 is being multiplied by itself four times, and it is not the same as cubing. The cubing of exponentials refers to the process of raising a number to the power of three or multiplying the number by itself three times. The commutative, associative, and distributive laws can be applied to simplify and rewrite exponential expressions. Therefore, to find an equivalent expression for 3.1⁴, you would need to multiply 3.1 by itself four times.
