Answer:
1. are you serious to ask ? it is written right there in the question itself. x=0, f(0)=y=6
2. the slope is 3
3. -4/3
4. $1.50 per book
5. -2
Step-by-step explanation:
1. the table itself says it for x=0. f(x) for x=0 is 6.
2. as explained do often already. the slope is the ratio of y/x showing how many units y changes, when x changes a unit or another surviving number of units.
the table shows when x increases by 1 unit, y increases by 3 units. so, the slow is 3/1 or simply 3.
3. again slope (see 2.).
going from M to N x increases by 4 units (from 1 to 5), and y decreases by 3 units (from 3 to 0).
so, the slope is y changes / x change = 4/-3 or simply -4/3
4. rate of change is
(f(a) - f(b)) / (a - b)
e.g.
(275 - 50) / (250 - 100) = 225 / 150 = 1.5
5. again very simple. which of the provided answer options appears in the f(x) column ?
the result of a function is the functional or y value calculated by the formula when responding the generic variable (like x) by the specified input value.
Answer:
a) P=0.6881
b) P=0.4292
c) P=0.9474
d) P=0.0051
e) P=0.9950
f) P=0.1048
Step-by-step explanation:
a) What is P(-1.5 < Z < 0.69)?
b) What is P(0 < Z < 1.47)?
c) What is P(Z > -1.62)?
d) What is P(Z < -2.57)?
e) What is P(Z < 2.57)?
f) What is P(-2.49 < Z < -1.22)?

Answer:

Step-by-step explanation:
Answer:
a ≈ 8.7 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
a² + 5² = 10²
a² + 25 = 100 ( subtract 25 from both sides )
a² = 75 ( take square root of both sides )
a = ≈ 8.7 ( to the nearest tenth )
