Answer:
3/7
Step-by-step explanation:
(# yellow)/(total #) = 135/315 = 3/7
The probability that a randomly chosen flower will be yellow is 3/7.
Answer:
B: Yes, because 5 miles is (8800) yards and 30 times around the route is ( ) yards.
Step-by-step explanation:
Delaney plans to run at least 5 miles each week for her health. Delaney has a circular route in the neighborhood to run. Once around that route is 420 yards. If runs that route times during the week, will cover at least 30 miles?
Answer:
X = -8 and X = 2
Step-by-step explanation:
X^2 + 6X - 6 = 10
Bring the 10 over:
X^2 + 6x - 16 = 0
From here, either use the quadratic formula or
manual factorization by finding its roots:
Manually:
(X + 8)(X - 2) = 0
Equate each factor to 0 you will get:
X + 8 = 0 and X - 2 = 0
Solutions are -8 and 2 respectively.
Answer:
Step-by-step explanation:
f(x) = 1/2 .2^x
We need to fill the table by putting values of x in the given f(x)
x = -2
f(x) = 1/2 .2^(-2)
f(x) = 1/2.1/2^2
f(x) = 1/2.1/4
f(x) = 1/8 = 0.125
y=0.125
x = -1
f(x) = 1/2 .2^(-1)
f(x) = 1/2.1/2^1
f(x) = 1/2.1/2
f(x) = 1/4 = 0.25
y=0.25
x = 0
f(x) = 1/2 .2^(0)
f(x) = 1/2. 1
f(x) = 1/2 = 0.5
y=0.5
x = 1
f(x) = 1/2 .2^(1)
f(x) = 1/2.2
f(x) = 1
y=1
x = 2
f(x) = 1/2 .2^(2)
f(x) = 1/2.4
f(x) = 2
y=2
x = 3
f(x) = 1/2 .2^(3)
f(x) = 1/2.8
f(x) = 4
y=4
Now we will plot these points. The graph is shown in the graph below.
A- because 48% is close to 50% which is 1/2
