Answer:
5 units
Step-by-step explanation:
Area of a triangle = 1/2 * b * h , b= base h=height
17.5 = 1/2 * b * 7
Multiply by 2,
35 = 7b
Divide by 7,
b = 35/7 = 5 units
Answer:
38°
Step-by-step explanation:
EFGH is an isosceles trapezoid (a trapezoid with two congruent legs is isosceles)
∠HGF=70° (base angles of an isosceles trapezoid are congruent)
∠EGH=32° (angles in a triangle add to 180°)
∠FGE=38° (angle subtraction postulate)
Answer:
The proportion of the population which is infected is =0.07692
Step-by-step explanation:
Let the events be,
A: a person is infected.
B: the test result is positve
According to the question we have,
So
Hence,
Now
The probability that a person is infected is
So the probability that a person is infected is =0.07692.
The proportion of the population which is infected is
Hence the proportion of the population which is infected is =0.07692
Answer:
The ratio between Rafael's sticks and Ricardo's is 0.5834
Step-by-step explanation:
In order to calculate the ratio between Rafael's ice cream sticks and Ricardo's we must take the total amount rafael has and divide it by the total amount Rafael has. Therefore this is done below:
ratio = Rafael's sticks / Ricardo's sticks
ratio = 35 / 60
ratio = 0.5834
The ratio between Rafael's sticks and Ricardo's is 0.5834
