Answer: 6:5
Step-by-step explanation: You can simplify the ratio 12 : 10 by dividing both terms by the greatest common factor (GCF)
The GCF of 12 and 10 is 2.
Divide both terms by 2.
12 ÷ 2 = 6
10 ÷ 2 = 5
ANSWER:
12 : 10 = 6 : 5

Answer:
27 cm
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2 +b^2 =c^2
a and b are the legs and c is the hypotenuse.We know one of the legs is 13 and the hypotenuse is 30
13^2 + b^2 = 30^2
169 + b^2 = 900
Subtract 169 from each side
169-169 +b^2 = 900-169
b^2 = 731
Take the square root of each side
sqrt(b^2) =sqrt(731)
b = 27.03
First, find the area of the rectangle. The formula is already given, and the length and width is shown on the 'beautiful drawing'.
The area of the rectangle is 171cm².
Find the area of the triangle. We see that it fits perfectly inside the triangle with some space to spare. It has the same height, so we have our 'h' value. Because there are 4cm and 3cm left for the width, subtract the sum of these numbers from the width.
, so the base of the triangle is 5cm long (remember that the figure isn't drawn to scale. I almost missed this one).
Final step. Subtract the area of the triangle from the rectangle: .
The area of the shaded region is 148.5cm².

Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population proportion is
The sample size is n = 408
Generally the standard deviation of the sampling distribution is mathematically represented as
=>
=>
Generally the probability that the sample proportion will differ from the population proportion by greater than 0.03 is mathematically represented as
So
=>
From the z table the area under the normal curve to the left corresponding to 2.778 and -2.778 is
and
So
=>
