The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the Sun :D
Answer:
Step-by-step explanation:
we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82
all the way around that isosceles triangle is 180 so
180-82 = 98
the angle at O is 98°
the arc BC spans 98°
angle 'a' is 1/2(98°)
a = 49°
Answer:
the answer is 40.1 cm
Step-by-step explanation:
The adjacent in the triangle is 23cm and the Alpha is 55 degrees, so just insert the formula to find the adjacent which is x .
Tq
Answer:
t-test for difference in slopes
no association exists
Step-by-step explanation:
t-test can be used to determine signifiance in difference in slopes of of fit vs time and not fit vs time graph
The data shows that as number of hours spent watchnig television increases, there is no increasing or decreasing trend in number of people fit or not fit. The number of people fit or not fit seems to be distributed around 629 for 1-2 hours of watching television. There trend is not consistent in both cases with increasing number of hours
Answer:
The chances of drawing a heart are therefore 1352 (which reduces to 14 . If we draw another card without replacing the first card, what are the chances of drawing a second heart? There are now 12 hearts in the deck out of 51 cards total and so the odds are 1251 (which reduces to 417 ).
Step-by-step explanation:
So we know that in a 52 card deck, there are 13 hearts, so our probability of drawing a heart on the first try is 13/52.
