I’m not sure if this is right but this looks a bit like chemistry so maybe try to get from minutes to seconds as it becomes an ‘S’ which I’m assuming is seconds? so basically try to do dimensional analysis with it and see if that works. Don’t forget to square it though, that’ll throw you off.
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
Answer:
Mr. Diaz has 185 peach trees
Step-by-step explanation:
x = peach trees
x + 162 = 347
solve to get x = 185
Answer:
10. 30km
11. 288km
12. 99km
Step-by-step explanation:
If 1cm=12km, just take the amount of cm and multiply by 12km.
For example, 2.5x12=30, and 24x12=288.
I hope this helps :)
The question is referred to a particular pair of triangles.
They are two "siamese" right triangles. The side that they share is the hypotenuse of both triangles.
The other sides that are marked as congruent are the heights of each triangle.
Then, you can use the Hypotenuse Leg theorem to prove the congruence of both triangles.
The hypotenuse leg theorem states that any two rigth triangles that have congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
