Michelle’s method WILL work because we have to add an extra 18% to the already total (100) michaels way would work if the tip was apart of the bill, but it is extra . Hence, Michelle’s method being correct
Complete question :
Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.
Millitary status _________ female ____ Male
In armed forces _________ 28 _______ 59
Millitary dependent ______ 928 ______ 781
Civilian _______________ 26393 ___27330
Answer:
Male = 0.4193
Female = 0.5087
Step-by-step explanation:
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206
The simplest fraction of 56/100 would be 14/25
Answer:
decrease
Step-by-step explanation:
the percent change measures FROM the first value. A change from 50 to 75 is a change of 50% (25 is the difference between the two numbers, and 25 is 50% of 50). A change from 75 to 50 is a change of -33.3% (25 is still the difference between the two. 25 is 33.3% of 75
B. (x-5) is a factor.
<u>Step-by-step explanation:</u>
To find out the relationship among the factor and an expression, we have to factorise it as,
2x² - 7x - 15
Here, sum = coeff. of x = -7
Product = constant × coeff of x² = -15 × 2 = -30
Now we have to find 2 numbers, which satisfies the above 2 conditions are -10 and 3.
-10 +3 = -7
-10× 3 = -30
2x² - 7x - 15
= 2x²- 10x + 3x - 15
Taking common terms as,
= 2x(x-5) +3(x - 5)
= (2x+3) (x-5)
So the expression is factorized and (x-5) is one of the factors of the expression.
