Answer: The slope is 2/3
Step-by-step explanation:
The difference in the rise (y-values) 2, divided by the difference in the run (x-values) 3, is 2/3.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (0, -1)
1 -(-1) ÷ 3 - 0
2 ÷ 3
2/3
The statement of the problem is
Kevin’s family has a history of diabetes. The probability that Kevin would inherit this disease is 0.75. Kevin decides to take a test to check if he has the disease. The accuracy of this test is 0.85
Probability
Test predicts he has it 0.85
Test predicts he doesn’t have it 0.15
Kevin has diabetes 0.75
<span>Kevin doesn’t have diabetes 0.25
</span>
Answers
<span>1) </span>The
probability that Kevin has diabetes and the test predicts he has diabetes
P=0.75*0.85=0.6375
<span>2) </span>The
probability that Kevin has diabetes and the test predicts the opposite to the
true
P=0.75*0.15=0.1125
<span>3) </span>The
probability that Kevin not have diabetes and the test predicts it correctly
P=0.25*0.85=0.2125
<span>4) </span>The
probability that Kevin not have diabetes and the test predicts he has diabetes
P=0.25*0.15=0.0375
Answer:
He is incorrect
Step-by-step explanation:
Although he can solve it, he would use Division Property or Equality not multiplication
hope this helps ;)
Answer: 1620 in.^3
Step-by-step explanation: Basically, you have a prism that has a base of 180, and a height of 9 in. The volume of a rectangular prism is length*width*height, and 180 is the length*width, so to find the answer, you do 180*9, which is equal to 1620.
23. 3^2 is 9 and 9 x 2 = 18 + 5 = 23
