First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)
4+5(9)
4+45
49
B
3.5, to 6.5, 9.5
aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
10th term
3.5+3(10-1)
3.5+3(9)
3.5+27
30.5
A is49
B is 30.5
A is answer
an=a1+d(n-1)
115+(-8)(14-1)
115-8(13)
115-104
11
answer is B
an=a1+d(n-1)
45+(-3)(10-1)
45-3(9)
45-27
18
C
Get a common denominator.
9/10
4/5 = 8/10
9/10 - 8/10 = 1/10
Answer: 1/10
Answer: option B is the correct answer
Step-by-step explanation:
Candace's backyard has a flower garden that covers 40% of her backyard.
If the total area of her backyard is 450 square feet, it means that her garden covers 40% of 450 square feet.
To determine how many square feet is her flower garden, we will find the value of 40% of 450 square feet. It becomes
40/100 × 450= 0.4×460 = 180 square feet
Answer
probability of greater than 3 is 60%
not 5,6,7 or 8 is 60%
