Answer:
It depends on the numbers and how many outliers there are
Step-by-step explanation:
Answer:
Step-by-step explanation:
line that is parallel to x-axis the slope = 0
an equation is : y= ax+b a = 0
passes through the point (3,5) : y =5 when x = 3 so : b = 5
an equation is : y = 5
Answer:
4.118 * 10^6
Step-by-step explanation:
When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.
41.18*10^5 = 4,118*10^6
(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)
The center of the circle is at (-2, 0). The radius is 5 units. The equation for a circle, in standard form is
.
We have our h and k from the center. h is the x coordinate and k is the y coordinate. The radius is 5. That means that the circle's equation, before simplifying, is
. After simplifying it is
. That's A and B. For C, we will simply pick points on the axes. One point on the circle is at (3, 0); another point is at (-2, 5); a third point is at (-7, 0). For D, the area of a circle is
.
For us that looks like this
. In terms of pi the answer is 25 pi, but in decimal form to the nearest square unit, it's 79 units squared.
75 is 75% of 100. If the dress was discounted at 25% then the original price would be $100
