Hey, it’s very easy. You just need to do like that:
z-2z-3=-7
z-2z= -7+3
-1z = -4 | : (-1)
z = 4
The answer is 4.
F(x) = sqrt(4-x)
You can get this by switching f(x) and x and then solving for f(x).
Answer:
1/4
Step-by-step explanation:
Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.
The probability of choosing one girl is:
15 / 25 = 3 / 5
Now, 24 students are left.
The probability of choosing one boy is:
10 / 24 = 5 / 12
Therefore, the probability of choosing one girl and one boy is:
3 / 5 * 5 / 12
= 3 / 12
= 1/4
Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V = 
area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V = × 16 × 4 = 
= 21 ft³
X(x-1)(x^2+4)=(x^2-x)(x^2+4)=(x^4)+(4x^2)-(x^3)-(4x)=(x^4)-x(x^2+4)+(4x^2)
