Answer:
A D E
Step-by-step explanation:
the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)
x + 4x - 85 = 90 Solve this to find the other 2 correct statements
5x - 85 = 90 Add 85 to both sides.
5x = 90 + 85 Combine
5x = 175 Divide by 5
5x/5 = 175/5
x = 35
Since ABD is a single x, that statement (D) is true.
4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
Answer:One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).
The p-value for that is 0.20, so by most tests this is not statistically significant.
Said another way, if there had been no change in the interval, the probability of having a repeat sample at least this different would be 0.20.
The parameter one is attempting to determine is the true proportion of adults in the US who say they like pizza.
For those who think it is 50%, it is essentially 100% likely that it is not 50% but much higher, around 75-77%.
