Y=16 x=20
put these values in equation and see rifht or wrong
A) 16 ≠20*20 wrong
B) 16 ≠ (5/4)*20 - wrong
C) 16=(4/5)*20 - right
D) 16≠0.6*20
Answer: C) y=4/5*x
Answer:
x = 3
Step-by-step explanation:
-6x - 20 = -2x + 4 (1 - 3x)
Distributive property
-6x - 20 = -2x + 4 - 12x
Combine like terms
-6x - 20 = -14x + 4
Add 14x to both sides
-6x - 20 + 14x = -14x + 4 + 14x
Simplifying
8x - 20 = 4
Add 20 to both sides
8x = 24
Divide both sides by 8
x = 3
Answer:
no i think you are just unlucky :)
Step-by-step explanation:
Answer:
What is the probability both are math phobic? 0.49%
What is the probability at least one is math phobic? 9.31%
Step-by-step explanation:
In order to both be math phobic, both individuals has to be inside of the probability of 7%, that means 0.07*0.07 = 0.0049 = 0.49%
In order to at least one be math phobic there's some cases which satisfies the sentence:
Individual A is math phobic and B as well = 0.07*0.07 = 0.0049 = 0.49%
Individual A is math phobic, but B is not = 0.07*0.63 = 0.0441 = 4.41%
Individual A is not, but B is math phobic = 0.63*0.07 = 0.0441 = 4.41%
Suming the 3 possibles cases, the probability at least one is math phobic
= 9.31%
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2
a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78
sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
