Answer:
3,264
Step-by-step explanation:
You have to use the straight line in the middle of the triangle as the height, the 12 below it as length, and the 34 on the side as width. And I must say, this prism is quite WIDE
You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Answer:
Step-by-step explanation:
12. To find the carpet needed. Find the area :
The figure is combination of semi circle and a rectangle.
So Area = Area of semi circle + Area of rectangle
Area = 150 + 39.25 = 189.25 sq ft
13. Cost per square feet = $$9.95
Therefore cost for 189.25 square feet = 9.95 x 189.25 = $1883.04
Answer:
You will have 21 positive results.
Step-by-step explanation:
Sensitivity of test:
Is the true positive rate, that is, the proportion of positive results that give positive tests.
Specificity of test:
True negative rate, that is, the proportion of negative results that give negative tests.
90% sensitive, 20 reliable people apply
0.9*20 = 18
95% specific, 60 unreliable people apply
1 - 0.95 = 0.05 of positive results.
0.05*60 = 3
How many positive results will you have?
18 + 3 = 21
You will have 21 positive results.
Answer:
2*2*7
Step-by-step explanation:
First do a number that can multiply up to 28
28=2*14
so keep the 2 , because it is a prime number, but 14 isn't so prime factorize it
2*14=2*2*7
2*2*7 is your answer because they all prime factors
