Answer:
1.25 cans or 1 1/4
Step-by-step explanation:
5 divided by 4 = 1.25
Vertical angles have the same degree
Make both angles equal
5x - 10 = 60
Solve the equation
5x = 70, x = 14
Solution: A
Answer:
180 tacos and 100 burritos was sold
Step-by-step explanation:
Let <em>t</em><em> </em>represent tacos
Let <em>b</em><em> </em>represent burritos
<em>t</em><em> </em>+ <em>b</em><em> </em>= 280
<em>2t</em><em> </em>+ <em>3b</em><em> </em><em>=</em><em> </em><em>660</em>
From t + b = 280,
t = 280 - b
Substitute t = 280 - b in 2t + 3b = 660
2t + 3b = 660
2(280 - b) + 3b = 660
560 - 2b + 3b = 660
560 + b = 660
b = 660 - 560
b = 100
Substitute b = 100 in t + b = 280
t + b = 280
t + 100 = 280
t = 280 - 100
t = 180
t = tacos = 180
b = burritos = 100
Answer:
a.Converge
b.Diverge
Step-by-step explanation:
We are given that



Because 
Hence, sequence An converges to
when n tends to infinity or - infinity.
=diverges
Necessary condition for a series to converge :
when n tends to infinity .
But
tends to
when n tends to infinity.
Therefore, given series is divergent.
Answer:
Mean = 10.2
Standard deviation = 4.0
Step-by-step explanation:
The average age = mean age
Mean = (16 + 10 + 5 + 7 + 13)/5
Mean = 51/5 = 10.2
What is the standard deviation will be square root of variance
(16 - 10.2) + (10 -10.2) + (5-10.2) + (7-10.2)+( 13-10.2)
5.8 + 0.2 -5.2 - 3.2 + 2.8
Square each number
33.64 + 0.04 + 27.04 + 10.24 + 7.84
Variance = 78.8/5 = 15.76
Standard deviation = 3.969 = 4.0
