Answer:
The first blank: not equal
The 2nd blank: not right triangle (it's acute triangle)
The 3rd blank: equal
The 4th blank: it's right triangle
Step-by-step explanation:
4^2 = 3^2 + 3^2
<=> 16 = 9 + 9
<=> 16 = 18 ( nonsense)
so triangle LKJ is not right triangle
5^2 = 4^2 + 3^2
<=> 25 = 16 + 9
<=> 25 = 25 ( make sense)
so triangle ABC is right triangle
Done!! :))
Answer: The regression equation could have a positive or a negative slope
Explanation:
The coefficient of determination is marked as r^2. This is always positive because squaring a negative leads to a positive. Knowing something like r^2 = 0.7 does not tell us whether r itself is positive or negative, so we don't know if the regression line slope is positive or negative. We would need more info.
Answer: 11
step by step instructions: so you have your statement. (3/7)r+(5/8)s you then would plug in (14) for (r) and (8) for (s).once you plug these in you then simplify the statement. (3/7)*14=6 and (5/8)*8=5. so your new statement should be 6+5=11
hope this helps
Answer:
16
Step-by-step explanation:
Sub in the number of customers (12) into the equation for the line of best fit, and solve.
y = 5/4 (12) + 1
y = 15 + 1
y = 16
There will be 16 positive YELP reviews
Which set of side lengths, in inches, will form a triangle? a 3.5, 7.2, and 3.0 b 10.0, 4.6, and 5.3 c 5.5, 4,9, and 10.5 d 3.2,
stealth61 [152]
Answer:
The correct answer is D
Step-by-step explanation:
To form a triangle, the sum of ANY two sides of the triangle must be greater than the length of the third side.
Looking at the first: 3.5+3.0 = 6.5 < 7.2, therefore it can't form a triangle since the sum of a pair of sides is less than the third side.
Looking at the second: 4.6 + 5.3 = 9.9 < 10.0, it's the same as the first.
Looking at the third: 5.5 + 4.9 = 10.4 < 10.5, it's the same as the first and second.
Looking at the last: 3.2 + 5.9 = 9.1 > 4.5, 3.2 + 4
5 = 7.7 > 5.9 and 5.9 + 4.5 = 10.4 > 3.2. Obviously, this fulfils the condition of a triangle. Any two sides is greater than the third, therefore the correct answer is D.
