Answer:
x = -2
Step-by-step explanation:
First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.
Now you find the sample variance. Subtract each number from the mean.
<span>15.5, 13.5, 8.5, -6.5, -10.5, -19.5 </span>
After, you square each value and add them.
<span>240.25+182.25+72.25+42.25+110.25+380.2... </span>
<span>= 1027.5 </span>
Now divide by 5 (because it's a sample variance) and you get 205.5.
Answer:
I may be wrong but 8 cups of chocolate
Step-by-step explanation:
First I looked over what I needed to do, 1 cup of cream and 2 cups of chocolate.
The next thing I did was attempt to solve it in 2 different ways, the first one being adding 1 cup of cream and 2 cups of chocolate every time, but that didn't work. The second attempt I just kept 1 cup of cream and added 6 cups of chocolate.
I added 6 because there are already 2 cups of chocolate, so that would add up to 8 cups. We didn't add any cups of cream so its still one. 8+1 is obviously 9.
Sorry if I am wrong
Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°
Answer:
$4.71
Step-by-step explanation:
you would multiply the radius times pi (you would get 6.42 ft) and then divide that by 1.35 (simplifying it to 642 divided by 135 and you would then get 4.706...)which rounds to the answer
