Answer:
$10.46
Step-by-step explanation:
Amount that can be won by Alexis ( xi ) = $0, $8 , $12
probability ( pi )
P( $0 ) = 13 / 52 = 1 / 4
P( $8 ) = 15 / 39 ( given that she wins this when an even number is drawn from three remaining decks )
P ( $12 ) = 1 - 15/39 = 24 / 39
a) Alexis expected winnings per game
= ∑ xi * pi = ( 0 * 1/4 ) + ( 8 * 15/39 ) + ( 12 * 24 / 39 )
= $0 + ( 120 / 39 ) + ( 288 / 39 ) = $10.46

Which expression represents how much money Jason gains from selling n balloons
and h party hats?
А
0.40n + 1.05h
B
0.60n + 1.45h
С
1.75nh
D
1.45h - 0.60n
Answer:
A.
Step-by-step explanation:
Balloons sell for $.50 - $.10 (Jason’s cost)= $.40 profit
Party hats sell for $1.25 - $.20 (Jason’s cost) = $1.05 profit.

What is the perimeter and area of the composite figure?
Step-by-step explanation:
▪AB = AC - EF
= 13 cm - 7 cm
= 6 cm
▪BD = CF - DE
= 16 - 8 cm
= 8 cm
BC = EF
perimeter = CF + EF + DE + AD + AB + BC
= 16 + 7 + 8 + 10 + 6 + 7
= 54 cm
Area of triangles = 1/2 × AB × BD
= 1/2 × 6 × 8
= 48/2
= 24 cm²
Area of rectangle = CF × EF
= 16 × 7
= 112 cm²
the total area = 24 + 112
= 136 cm²

Step-by-step explanation:
simplefy the expresion wich will equal 58
Answer:
1) Marcus 2) Lillian 3) Pablo
Step-by-step explanation:
For these type of expressions you have to use "PEMDAS"
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
(IT ALWAYS HAS TO GO FROM LEFT TO RIGHT)
1) Marcus Why Marcus?
Because, Melanie added instead of dividing first.
Melanie: Marcus:
8 x 7 + 14 / 7 8 x 7 + 14 / 7
56 + 14 / 7 56 + 14 / 7
70 / 7 56 + 2 <---
10 58
2) Lillian Why Lillian?
Because, Landon Multiplied instead of dividing.
Lillian: Landon:
50 / ([tex]5^{2}[/tex] - 15) x 5 50 / ([tex]5^{2}[/tex] - 15) x 5
50 / (10) - 5 50 / (10) - 5
5 x 5 50 / 50 <---
25 1
3) Pablo Why Pablo?
Because, Pamela didn't follow the L --> R- (Left to Right) -Rule.
Pablo: Pamela:
(12 + [tex]2^{2}[/tex]) / 4 x 5 (12 + [tex]2^{2}[/tex]) / 4 x 5

7.1.13 Question Help Use the sample data and confidence level given below to complete parts (a) through (d). A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=992 and x = 570 who said 'yes." Use a 99% confidence level. B Click the icon to view a table of z scores. a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.)
Answer:
The Point estimate of the Population proportion E = 0.039≅0.04
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 992
and x = 570
The Population proportion
[tex]p = \frac{x}{n} = \frac{570}{992} = 0.5745[/tex]
Step(ii):-
The point estimate of the Population proportion is determined by
[tex]E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }[/tex]
E = 0.039≅0.04
Final answer:-
The point estimate of the Population proportion E = 0.039≅0.04
