Answer:

Base = 6 cm

Step-by-step explanation:

Area of Triangle = \frac{1}{2} .{base}.{Height}

Where A = 18 cm², h = 6 cm

Putting in the above formula

18 = \frac{1}{2}(base)(6)

18 = 3(base)

base = 18/3

Base = 6 cm

Answer:

h = 6 cm

Step-by-step explanation:

Atriangle = b×h/2

18cm² = 6cm×h/2

36cm² = 6cm×h

h = 36cm²/6cm

h = 6 cm

Step 2:

Part A

f(x) = a(x-h)^2 +k

Part B

I'm not really sure about this part

Part C

f(x)=-12/25(x-25)^2+32

Step 3:

Part A

y = ax^2 + bx + c

Part B

f(x) = -12/25(x - 25)^2 + 32

Part C

a = -12/25

b = 0

c = 32

Find the indicated probability by using the complementation rule. A percentage distribution is given below for the size of famil
arlik [135]

Answer:

The correct option is c.

Step-by-step explanation:

The percentage probability distribution is:

Size (X)      Percentage

 2                   39.9

 3                   24.4

 4                   20.1

 5                   10.8

 6                    3.3

 7                     1.5

Total             100.0

Compute the probability that the size of the family is 4 or more as follows:

P (X ≥ 4) = P (X = 4) + P (X = 5) + P (X = 6) + P (X = 7)

              = 0.201 + 0.108 + 0.033 + 0.015

              = 0.357

Thus, the probability that the size of the family is 4 or more is 0.357.

The correct option is c.
