1. Enrique tossed two fair coins ten times. He recorded whether each coin landed on heads, H, or tails, T. The outcomes are shown in the table

O 30
O 45
O 15
O 67

Based on the results in the table, predict the number of times both coins will land on
tails if Enrique tosses two coins 150 times

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

sorry i got nothing

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
