<span>X(1+y)=z
Multiply x by 1 and y
x + xy=z
Divide y on both sides
x + x = z/y
Add x to x
2x = z/y
Divide 2 on both sides
Final Answer: x= z/y/2  
Word Form: x equals z divided by y all over two.

Liz flips a coin 30 times. The coin lands heads up 21 times and tails up 9 times. Complete each
SSSSS [86.1K]

Answer:

Pr = 0.50

Step-by-step explanation:

Given

n = 30

H = 21

T = 9

See attachment for complete question

Required

P(H)

The question requires that we calculate the theoretical probability of landing on the head.

This means that, we have to ignore the given data, and we use the following

S =\{H,T\} --- sample space

n(S) = 2 --- sample size

n(H) = 1 --- occurrence of Head

So, the theoretical probability is:

Pr = n(H)/n(S)

Pr = 1/2

Pr = 0.50

Find the area of the figure below<br><br> A.288.62<br> B.266.22<br> C.186.66<br> D.236.6
Archy [21]

Answer:

A. 288.62

Step-by-step explanation:

Area of two triangles = 15.3 * 10.4 = 159.12

Area rectangle = hypotenuse triangle * 7

hypotenuse = √108.16 + 234.09

Hypotenuse = 18.5

Area rectangle = 18.5 * 7 = 129.5

129.5 + 159.12 = 288.62

Answer = A. 288.62
