Answer: (-2, 2) and (4, 8)
There are two solutions because the two functions cross each other twice.
She will finish them at 2:25
Explanation: if you add for hours it would equal 2 then when you add 10 to 15 it would be 25 so the answer would be 2:25 hope to his helps:)
Answer
given,
the standard deviation:-
of the students height in the class = 4.2 inches
of the male heights in the class = 3.4 inches
of females height in the class = 3.3 inches
standard deviation is the deviation of the value from the target value.
the given question standard deviation of the students is more than that of the individual standard deviation of the heights of males and females because of the distribution of the entire class has more dispersion.
Answer: 105 of them are hummingbirds.
Step-by-step explanation:
I there are a total of 350 birds then 30% o 350 will give the number o hummingbirds.
350 of 30%
350 * 0.3 = 105
Answer:
Step-by-step explanation:
I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.
11) tan45 = x/13 x = 13
cos45 = 13/y y = 13√2
12) sin30 = 4/x x = 8
tan30 = 4/y y = 4√3
13) sin60 = 21/x x = 21(2/√3) = 42/√3
y = xcos60 = (42/√3)(1/2) = 21/√3
14) cos45 = x/22 x = 22/√2
sin45 = y/22 y = 22/√2
15) Height = 24sin30 = 12
cos 45 = 12/x x = 12/√2
tan45 = y/12 y = 12
cos30 = z/24 z = 24(√(3)/2) = 12/√3
