b. sin 43°
c. tan 43°
d. cos 133°
B.....
cos (47°)= sin (90°-47°)=sin (43°) [complementary angles]
Answer B
Answer:
8125, im pretty sure this is right
Step-by-step explanation:
<span>Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is
(154-69)/(429-139)
=85/290
=0.2931~0.29
Answer: A. 0.29
</span><span>The probability of having a hemoglobin level above 11 is
P(H>11)
=154/429
=0.35897~0.36
Answer: </span><span>C:0.36
</span><span>Being older than 25 years and having a hemoglobin level above 11
</span>Are not dependent on each other because w have not been told about any factors that were included in selection of sample.
Answer: <span>B.are not</span>
Answer:
y=-3/5x+6.6
Step-by-step explanation:
formula y2-y1/x2-x1, y-y2=m(x-x2)
-3-0/6-1
-3/5
y-(-3)=-3/5(x-6)
-3/5*x = -3/5x
-3/5*6 = 3.6 (18/5)
3.6 +3
y=-3/5x+6.6
