Can someone pls help me to solve 15 and 16 and answer 17 I will mark you the brainly pls I will really appreciate
Answers
Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type your answer as a Percentage rounded to 1 decimal.
Answers
Answer:
1.3%
Step-by-step explanation:
Phat = 0.53
1 - phat = 1 - 0.53 = 0.47
Sample size, n = 5913
Assume the confidence level = 95%
Zcritical at 95% = 1.96
Margin of Error = Zcritical * √(phat(1 -phat)) / n
Margin of error :
1.96 * √((0.53 * 0.47) / 5913)
1.96 * 0.0064905
= 0.0127215
= 0.0127215 * 100%
= 1.272%
= 1.3%

Select an equation that is equivalent to a^2-144b^2 a) (a-12b)^2 B) (a+12b)^2 C) (a-12b)(a+12b) C) a^2-24ab+144b^2
Answers
Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
*(a+12b)
a²- 12ab
+12ab - 144b²
a² +0 - 144b²
We see we get the same answer as applying the formula above.

Remark
This is one of those things that when you see it, you think that really is something.
The trick is to subtract a smaller right triangle from a larger one.
The base for both triangles is 4 (going from where the right angle is to your right where the lines of the red enclosure meet.
Calculations
The height of the larger triangle is 8
The height of the smaller triangle is 5

Decrease 117 kg in the ratio 10:13
Answers
Answer:
90kg
Step-by-step explanation:
it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.
The value 117kg decreased in the ratio 10:13 will be 90kg
Ratios and proportionGiven the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:
Step 1: Multiply 117 by the smallest value
117 * 10 = 1170
Step 2: Divide the result by the largest value to have:
Value = 1170/13
Value = 90kg
Hence the value 117kg decreased in the ratio 10:13 will be 90kg
