Answer:xscscx
Step-by-step explanation:
X = -b +- sqrt(b^2 -4*a*c)/2a
x = (-10 +- sqrt(10^2 -4*3*-5) )/6
x = (-10 +- sqrt (100 + 60) )/6
x = (-10 +- sqrt (160) )/6
x= (-10 +- 4sqrt10)/6
x = (-5 +- 2sqrt10)/3
x = (1 +- sqrt(1-4*2*6))/4
x= (1+-sqrt(1-48))/4
x = (1 +- sqrt(-47))/4
x = (1 +- i* sqrt(47))/4
x = (-2 +- sqrt(2^2-4*5*5))/10
x = (-2 +- sqrt(4-100))/10
x =(-2+- sqrt (-96))/10
x = (-2 +- 4i sqrt6))/10
x = (-1 +- 2i sqrt6))/5
The measure of angle EAC is equivalent to 50 degrees.
Numbers 1, 2 and 3 are attached while 4 & 5 will be written down.
4. the histogram and stem/leaf plot are showing the exact same data, and the data is sorted by the same grouping. the frequency table shows a different grouping but the same data is shown more in-depth.
5. the number of leaves, frequencies, and the height of the bars are related because they are different ways of showing the same groups of data just in different ways. The impact that the choice of intervals makes on this relationship in the data is how concentrated, or diverse the data is.
Hope I helped!
Answer:
A)72
Step-by-step explanation:
They have essentially divided up the line 2 different ways, into 2 parts and into 10 parts. The 2 parts is from 1 and 2 and then the 10 parts is because of the ratio 4-6. The 2 parts are not equal because one of them is 4 parts of the line and the other is 6, if we put that together we get the 10 equal parts of the line. A line is equal to 180 degrees meaning that we can divide that my 10 to figure out how much each part is equal to 180/10 is 18 so each of the 10 parts is equal to 18. We are looking for <1 which it says is equal to 4 parts so we will multiply 4 by 18 to get how much it is. 4 times 18 is 72 so the answer is A
I hope this helps and please don't hesitate to ask if there is anything still unclear!
