The answer to your question is D
I think it is B, since x goes right 4.5 times and y goes up 3 times.
Did you figure out the answer cause i need it
Answer:
x=3
Explanation:
Let's write an equation for the area of this figure.
This figure can be divided into 2 rectangles, a vertical and horizontal rectangle.
Area of rectangle= length× breadth
Area of vertical rectangle= 6x
Length of horizontal rectangle= (7 -x) cm
Area of horizontal rectangle= x(7-x)
Since total area= 30 cm^2,
6x+ x(7-x)= 30
6x +7x -x^2= 30 (expand)
-x^2 +13x-30= 0 (bring all terms to one side)
x^2 -13x +30= 0 (divide by -1)
(x -10)(x -3)= 0 (factorise)
x -10= 0 or x -3= 0
x= 10 or x= 3
(reject)
We reject x=10 since from the diagram, x cm is less than 6cm.
The probability that a U.S. household selected at random has a computer and has Internet access will be 0.72. The C and I are independent events. Then the correct option is B.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Approximately 80% of households in the United States have computers. Of those 80%, 90% have Internet access.
Then the probability that a U.S. household selected at random has a computer and has Internet access will be
P(C and I) = 0.80 × 0.90
P(C and I) = 0.72
Then the C and I are independent events.
Then the correct option is B.
