Answer:
The fraction of females on the maths course at university is 3/4
Step-by-step explanation:
Males = x
Females = 3x
Males + Females = x + 3x = 4x
The fraction of the course that are females
Females fraction = Females/Males + Females
Females fraction = 3x/4x= 3/4
which means that for every 4 people 3 are females and 1 male
#1 is A & B (points connect)
#2 is A & B & D (because they all touch)
#3 I don't know
#4 I think it's G, C, & F
#5 D
Answer:
the sine of angle R is 5/7.
Step-by-step explanation:
Recall that the sine function is defined as sin Ф = (opposite side) / hypotenuse.
The side opposite Angle R is √65 and the hypotenuse is √91.
Thus, the sine of angle R is sin R = √65 / √91, or 5/7.
Answer:
m = -2
Step-by-step explanation:
As one goes from (2, 7) to (4, 3), we note that x increases by 2 and y decreases by 4. Thus, the slope is m = rise / run = -4/2, or -2
The slope of the line connecting these two points is -2.
