Answer is -10.
x-intercept, y=0, substitute for y in the equation. you will have -2x+5(0)=20
-2x =20
x =20/-2
x=-10
Yes, it is B. As the hour increases by 1, the snow on the ground (in cm) increases by 2.
Standard form for a linear equation (highest degree is 1), is Ax+By=C;
y-1=(-2/3)(x-4) <-- expand and isolate y
y-1=-2/3x+8/3
y=-2/3x+(8/3+1)
y=-2/3x+(8/3+3/3)
y=-2/3x+11/3 <---remove fraction;
3y=-2x+11 <-- rearrange to given format
2x+3y=11
Hope I helped :)
Answer:
Total cards in a deck=52
Face cards =12
So probability of picking a face card is 12/52=3/13
Step-by-step explanation:
Usually there are 12 face cards in a group, so that would be 12/52 -- but wait! You can simplify, always. check. for. simplifying. possibilities.
Usually in an answer they will include both simplified, and not simplified. Believe it or not, usually they ask for the simplified. Make sure you read carefully.
Answer:
To three decimal place = 0.030
Step-by-step explanation:
Let probability of death in white p (WH) = 86%
Let probability of death in black p(B) =12%
Let probability of death in Asian p(A) = 2%
Probability of death caused by diabetes among white will be 2.8% of p (WH) = 0.86 x 0.028 = 0.02408
Probability of death caused by diabetes among black will be 4.4% of p (B) = 0.12 x 0.044 = 0.00528
Probability of death caused by diabetes among Asian will be 3.5% of p (A) = 0.02x 0.035 = 0.0007
If a sample is chosen and the cause is diabetes then the probability will be
Probability of death caused by diabetes among white or Probability of death caused by diabetes among black or Probability of death caused by diabetes among Asian
0.02408 +0.00528 +0.0007 = 0.03006
To three decimal place = 0.030
