When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard devia
alukav5142 [94]

Answer: 90% of the time.

Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.

What is the area of Figure ABCD?<br><br>104<br>120<br>136<br>168​
EleoNora [17]

The answer is 120 because 13 times 8 equals 104, and all you have to do is find the base edge length of the triangle which is found by subtracting 13 from the 17 and getting 4 for the triangle base length, multiplying it by the height (8) which you get 32, dividing it by two to get 16, add 104 and there's your answer.

jeka94

Answer:

y = -11x - 13

Step-by-step explanation:

Step 1: Subtract 11x from both sides.

  • y=-11x-13

Therefore, the answer is y = -11x - 13.
