Answer:

(4, 3)

Step-by-step explanation:

Since, A (-4, 3) is reflected across the y-axis to obtain point B.

Marianna [84]

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

What does this mean ---->> 9e+10 please explain the answer

GenaCL600 [577]

This expression can't be solved because we don't know the value of e. Basically what this means is that e, an unknown number, is first being multiplied by 9, and it is then added by 10. You will just leave it as it is.
