Answer:
10 minutes for 480 copies. Divide 480 by 10 and get 48 copies per minute. If you divide 720 by 48 you get 15, so it takes 15 minutes to make 720 copies.
Step-by-step explanation:
You are using a^2+b^2=c^2
since c is the hypotenuse
#1 the equation would be 16^2+b^2=34^2
16^2= 256
34^2= 1156
1156-256= 900
b^2=900 (now find square root of 900)
b= 30
You are now trying to find the hypotenuse or c in this so it is simpler
#2 equation - 4^2+2^2=c^2
16+4=c^2
20=c^2
c= 4.27

Step-by-step explanation:
A triangle is 180º. We have two angles; 60º and 60º
60+60 = 120
180-120 = 60º
This means that this is an equilateral triangle and all the sides are the same length.

Answer:
slope = -4
Step-by-step explanation:
rise/ run = 4/1, but slope always minus, so slope = -4
Step-by-step explanation:
H0 : µ ≤ 26.9
Ha : µ > 26.9
a. since the null hypothesis is rejected, we would accept the alternative hypothesis and come to the conclusion that there is enough evidence that beer and cider consumption are higher than 26.9 in the city.
b. type 1 error happens when we reject a true null hypothesis.
this error error in this question would be that our conclusion that beer and cider consumption is greater than 26.9 is not true. what is true is that it is equal to or less than 26.9.
the consequence is that is h0 is false it would be harder to reject it at a lower level of significance.
c. type ii error happens when the null hypothesis is accepted even though it is false. here, error would be that cider we accepted that cider and beer consumption is less than or equal to 26.9 when it is actually greater than 26.9
the consequence is that it would be harder to accept a true h0 at a high level of significance
