Answer:
3156
Step-by-step explanation:
- <em>Used formula:</em>
- <em>(1² + 2² + 3² + ... + n²) =1/6*n(n + 1)(2n + 1)</em>
--------
- 10²+12²+14²+......+26² =
- (2*5)²+(2*6)² + (2*7)² + ... + (2*13)² =
- 4*(5²+6²+7²+...+13²) =
- 4*(1²+2²+...+13² - (1²+2²+3²+4²)) =
- 4*(1/6*13(13+1)(2*13+1) - (1+4+9+16)) =
- 4*(1/6*13*14*27- 30) =
- 4*(819 - 30) =
- 4*789 =

Answer:
Her rent is $1072.5
Step-by-step explanation:
Monthly budget: $3,575
Her rent is 30% of her monthly budget. Since 30% = 0.3, we can multiply our monthly budget with 0.3 to get 30% of it.
30% * 3575 = 0.3 * 3575 = 1072.5
Answer: $1072.5
The locations specified in the order regarding the shape will be B. longest side AC; smallest angle ∠C.
<h3>How to express the information?</h3>
From the information given, in the triangle where A = 59°, B is unknown, and C = 41°. Therefore, the value of B will be:
= 180° - (59° + 41°)
= 180° - 100°
= 80°
Therefore, the locations specified in the order regarding the shape will be longest side AC; smallest angle ∠C.
In conclusion, the correct option is B.

Answer:
with a .95 probability, the sample mean will provide a margin of error 0.196
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in the .95 confidence level (1.96)
- s is the population standard deviation (1 min.)
- N is the sample size (100)
ME=
=0.196
95% confidence interval for check-out time would be 3 ±0.196 min
