Which is one reason why this expression is equal to 0?
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62} [/tex]
Answer:
0
Step-by-step explanation:
The given expression is :
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62}[/tex]
We can solve the expression as follows :
[tex]\frac{ - 5.62 + 5.62}{5.62}=\dfrac{0}{5.62}[/tex] (As -5.62+5.62 equals to 0)
Any number multipled to 0 gives 0.
Hence, the value of the given expression is equal to 0.

amount, how many
chicken wings would each
person get?
Answer:
5 chicken wings per person
Step-by-step explanation:
if they cooked 34 to begin with then added 11 so
34+11=45

John works two jobs. He earns $10 an hour babysitting his neighbor's children and $15 an hour mowing lawns in his neighborhood. Last week he worked a total of 20 hours and earned a total of $240.
Drag and drop numbers in the boxes to create an equation which models this situation if x = the number of hours he spent babysitting and y = the number of hours he spent mowing lawns last week.
The number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given that, John works two jobs. He earns $10 an hour babysitting his neighbour's children and $15 an hour mowing lawns in his neighbourhood. Last week he worked a total of 20 hours and earned a total of $240.
Let the x be the number of hours he spent babysitting and y be the number of hours he spent mowing lawns last week,
Establishing the equation, we get,
x+y = 20
x = 20-y......(i)
10x+15y = 240.......(ii)
Using the equation (i) in (ii), we get
10(20-y)+15y = 240
200-10y+15y = 240
5y = 40
y = 8
Put y = 8 in eq(i)
x = 20-8
x = 12
Hence, the number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

The angle of elevation to the top of a flagpole is 50 degrees if the angle of elevation was measured 24 m from the flagpoles base wich expression can be used to find the height of the flagpole
Answer:
Tan 50 = H/24
Step-by-step explanation:
The set up will give a right angled triangle;
Given the following
angle of elevation = 50degrees
Distance of elevation from the flagpole base = 24m (Adjacent)
Required
Height of the flagpole (Opposite) = H
Using the SOH CAH TOA identity
Tan theta = opposite/adjacent
Tan 50 = H/24
H = 24tan50
H = 24(1.1918)
H = 28.60
Hence the required expression is Tan 50 = H/24 where H is the height of the flagpole
The height of the flagpole is 28.60.
Given
The angle of elevation to the top of a flagpole is 50 degrees.
The angle of elevation was measured 24 from the base of the flagpole.
The angle of elevation;The angle of elevation of the sun is the angle formed between the horizontal line and your line of sight when you look at the sun.
Let the height of the flagpole be H.
Then,
The height of the flagpole is given by;
[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\ \rm Tan50=\dfrac{H}{24}\\\\H = 24 \times tan50\\\\H = 24\times 1.91\\\\H=28.60[/tex]
Hence, the height of the flagpole is 28.60.

a. Express the odds for each actress winning as a probability. (Round your answers to 3 decimal places.)
Best Actress Probability
Anne Hathaway
Angelina Jolie
Melissa Leo
Meryl Streep
Kate Winslet
Answer:
Anne Hathaway: 0.154 = 15.4%
Angelina Jolie: 0.048 = 4.8%
Melissa Leo: 0.029 = 2.9%
Meryl Streep: 0.231 = 23.1%
Kate Winslet: 0.714 = 71.4%
Step-by-step explanation:
Odds to probability:
Odds of a:b
The probability is given by:
[tex]p = \frac{a}{a+b}[/tex]
Anne Hathaway 2:11
So [tex]p = \frac{2}{2+11} = \frac{2}{13} = 0.154[/tex]
Angelina Jolie 1:20
So [tex]p = \frac{1}{1+20} = \frac{1}{21} = 0.048[/tex]
Melissa Leo 1:33
So [tex]p = \frac{1}{1+33} = \frac{1}{34} = 0.029[/tex]
Meryl Streep 3:10
So [tex]p = \frac{3}{3+10} = \frac{3}{13} = 0.231[/tex]
Kate Winslet 5:2
So [tex]p = \frac{5}{5+2} = \frac{5}{7} = 0.714[/tex]

Answer:
1.)
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
Conditional probability ;
0.47
Step-by-step explanation:
Let :
E = Excellent ; A = Average ; N = not up to standard
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.
The probability that Leo is coming :
Leo ; Excellent = 0.7
Leo ; Average = 0.3
Leo; Not up to standard = 0.2
Hence, probability they Leo is coming :
(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)
0.35 + 0.06 + 0.06
= 0.47
