1. find the area of the two triangles, including the shaded section. the formula for this is a=1/2bh
the height and base are both 24 inches. this is because you add the 10 from the side of the square to the 14 that is given
so:
a=1/2(24)(24)
a=(12)(24)
a=288 sq. inches
since there are two triangles, you would multiply the area by 2
a=2(288)
a=576 sq. inches
now, since you only need the unshaded section, you have to take away the shaded section, which is a square. to do this, you must calculate the area of the square and take it away from the area of both triangles.
a=576-(lw)
a=576- (10)(10)
a=576-100
a=476 sq. inches
that is your answer
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257
Answer:
C
Step-by-step explanation:
if you put the x numbers (miles) in the x spot in the equation you will get your y answer. which ever one matches is your answer
Answer:
Caras hourly wage is $10.08 after 3 years
Step-by-step explanation:
4% of 9
0.04 x 9 = 0.36
then you multiply 0.36 by 3 because you are solving for 3 years.
0.36 x 3 = 1.08
then you add 1.08 to 9 because Cara's wage goes up $1.08 in 3 years
1.08 + 9 = 10.08
answer:
Cara's hourly wage is $10.08 after 3 years of working
