Answer:
Wt
Step-by-step explanation:
300times, because 6xs10^5 is equal to 600000 and 2xs10^3 is 2000, and if you divide you would get 300
Answer:
single sample z test
Step-by-step explanation: The correct statistics test is the single sample A test.
A one-sample z-test is used to test whether a population parameter is remarkably different from some hypothesized value. Each makes a statement about how the true population mean μ is related to some hypothesized value M. It is used to test whether the mean of a population is greater than, less than, or not equal to a specific value.
5) So for parallelogram ABCD, ∠B ≅ ∠D, and ∠A ≅ ∠C. Further, ∠B and ∠A are supplementary (i.e., their sum is 180°), and ∠D and ∠C are also supplementary.
So, we have that m∠B = m∠D. Therefore,
.
Now, let's substitute for x back into the expression for either ∠B or ∠D to find it's angle measure.
m∠B =
Now, remember that ∠B or ∠D are supplements of ∠A.
So, m∠B + m∠A = 180°.
That means m∠A = 180° – 72° =
108°.
That seems reasonable, because A appears to be an obtuse angle.
6)
m∠BAE + m∠DAE + m∠ABC = 180°
∠ABC ≅ ∠ADC.
m∠ABC =
m∠ADC =
81°.
7)
DC =
29
This is very simple, you can use tally marks to find the amount of birthdays. Then divide it by 100. Good luck !
