Answer:
0.1354
Step-by-step explanation:
Relevant data provided as per the requirement is shown below:-
Female probability of age between 55 to 69 = 2058
Male probability of age between 55 to 69 = 4571
According to the given situation, the calculation of probability is shown below:-
![= \frac{Female\ from\ 55\ to\ 69 }{Total\ female}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BFemale%5C%20from%5C%2055%5C%20to%5C%2069%20%7D%7BTotal%5C%20female%7D)
where,
Total female is
= 143 + 2333 + 4027 + 5178 + 2058 + 1459
= 15,198
And, the female is 2058
So, the probability is
![= \frac{2058}{15,198}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2058%7D%7B15%2C198%7D)
= 0.1354
Therefore for computing the probability of female that lies between 55 to 69 we simply applied the above formula.
5. -6x(x-(-2))= pemdas, -6x(x+2), distribute, -6x^2-12x
11. 7xy
14 count how many x's there are and add so 6+7+1=14 so 14x
15. combine tems with exponets with exponents so 8x^2+8x
16.count how many y's ther are and add so 1+1+2+1=5 or 5y
Answer:
a = 8
Step-by-step explanation:
-5(a + 3) = - 55
- 5a - 15 = - 55
55 - 15 = 5a
5a = 40
a = 40 : 5
a = 8
Answer:
a) 55 b)=21/32 c)x=6
Step-by-step explanation:
a)Follow the PEMDAS order of operations
Calculate within parentheses
(6 +3 x 2)
(6+6)
= 12
=51+ 12 ÷ 3
Multiply and divide (left to right)
12÷ 3=4
51 +4
Add and subtract (left to right)
51 + 4=55
B)
Follow the PEMDAS order of operations
29 – 8) ÷ 32
Calculate within parentheses
(29 – 8) =21
= 21 ÷32
Multiply and divide (left to right)
21 ÷32
=21/1× 1/32
=21/32
C)let the unknown be X
6+ 5× X- 16 = 20
Group like terms
5x +6- 16 = 20
Add/Subtract the numbers:
6- 16 = -10
5x - 10= 20
Add 10 to both sides
5x- 10 + 10 =20 + 10
Simplify
5x=30
Divide both sides by 5
5x/5=30/5
x=6
