Answer:

36 units²

Step-by-step explanation:

I used the triangles' area to find the area of the quadrilateral. The area of a triangle is 1/2 x base x height. The top triangle is 1/2 x 5 x 10 or 25. The bottom triangle is 1/2 x 2 x 11 or 11. Add 25 + 11 to get the total area.

Hope it helps!

Honeybees produce 7 pounds of honey for every 1 pound of beeswax they produce. Use

trapecia [35]

Honey produced: Beeswax = 7:1 Therefore, if you have 25 pounds of beeswax, you need to divide 25 by 1, giving you 25. This will then show you what you need to multiply the amount of honey produced by. 7x25=175. Therefore, if you have 25 lbs of beeswax, you'll be able to make 175lbs if honey Hope this helps :)

Suppose scores on exams in statistics are normally distributed with an unknown population mean and a population standard deviati

Anna71 [15]

Answer:

( 67.18, 68.82)

Step-by-step explanation:

Let $\mu$ be the true (population) mean of statistics exam scores. We have a large random sample of n = 36 scores with a sample mean (sample mean score) of $\bar{x} = 68$ . We know that the population standard deviation is $\sigma = 3$ . A pivotal quantity is $(\bar{x}-\mu)/(3/\sqrt{36}) = (\bar{x}-\mu)/(3/6) = (68-\mu)/(1/2)$ which is approximately normally distributed and $P(-z_{0.05}\leq(68-\mu)/(1/2)\leq z_{0.05}) = 0.90$ where $-z_{0.05} =-1.6449$ , and so, $P(-1.6449\leq(68-\mu)/(1/2)\leq 1.6449) = 0.90$ . Therefore the 90% confidence interval is (68-(1/2)(1.6449), 68+(1/2)(1.6449)), i.e., ( 67.18, 68.82)
