6/8 of the cookies where shaped like circles and 2/8 of the cookies where shaped like squares *sorry if I’m wrong*
Answer: 5.83 miles
Step-by-step explanation:
Mean = 110
Sample size = 45
Standard deviation = 6
Z score for 90% is 1.645 ( from Z-table).
Lower Limit = Mean - Z(SD/√Sample size))
Lower limit = 110 - 1.645(6/√45)
Lower limit = 108.5
Upper Limit = Mean + Z(SD/√Sample size))
Lower limit = 110 +1.645(6/√45)
Lower limit = 111.5
The interval is (108.5, 111.5)
1 = 60
2 = 120
3 = 25
triangles have total angles of 180 40+80=120
180-120=60
straight lines have total angles of 180
180-60=120
triangles have total angles of 180
120+35=155
180-155=25
Answer:
Step-by-step explanation:
∵A= l×b
⇒A= 4ab^2 × 6a^2b
⇒A= 24a^2b+1×b^2
Explanation: When multiplying indices, add the exponents of similar bases (that is, a^2×a = a^2+a^1 =a³) thus a^2b+1.
I hope this helped.
