<span>The question is asking for the total of 36, 78, 198, 475 and 620. The correct option is B, that is, 1,407. Total refers to summation of a set of number, thus if the given numbers are added together, the sum total will be 1, 407. That is, 36 + 78 +198+475 + 620 =1, 407. Other words that can be used in place of total are: summation, addition or plus.</span>
Answer:
The answer is 6 1/3 divided by 2 which is 3 1/6
Step-by-step explanation:
Her total cost is $19.50
$3.30 x 3 = $9.90
+
$3.20 x 3 + $9.60
=
19.50
Or your answer could be 19.5
(It’s the sum either way.)
Answer:
160π cm²
Step-by-step explanation:
The area of the shaded region is
area of outer circle - area of inner circle
A = πr₁² - πr₂²
r₁ is the radius of the outer circle = 10 + 3 = 13 cm
r₂ is the radius of the inner circle = 3 cm
A = π × 13² - π × 3²
= π(169 - 9) = 160π cm² ≈ 502.65 cm² ( to 2 dec. places )
Answer:
The probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a person lives in a mobile home.
<em>Y</em> = a person dies as a result of tornado.
Given:
Compute the value of 
as follows:
Compute the probability that a person dies as a result of tornado as follows:
Then the probability that a person does not dies as a result of tornado is:
Compute the value of 
as follows:
Thus, the probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
