Answer:

Alix does. See below.

Step-by-step explanation:

Givens

Jenny

b1 = 90 cm
b2 = 80 cm
height = 23 cm

Alex

b1 = 90 cm
b2 = 70 cm
height = 27 cm

Formula

For both territories the answer is based on the formula

Area = (b1 + b2)*h/2

Solution

Jenny

Area = (90 + 80)23/2
Area = 170 * 23 / 2
Area = 85 * 23
Area = 1955 units.

Alex

Area = (70 + 90)*27/2
Area = 160*27 / 2
Area = 80* 27
Area = 2160

Alix does by 205 cm

an experiment consists of flipping a fair coin 4 times. What is the probability of obtaining at least one head?

Dvinal [7]

$\mathbb P(X\ge1)=1-\mathbb P(X=0)$

The probability of getting 0 heads in 4 tosses (or equivalently, 4 tails) is $\dfrac1{2^4}=\dfrac1{16}$ .

So the desired probability is

$1-\dfrac1{16}=\dfrac{15}{16}$
