Answer:
9/13 = 0.6923
Step-by-step explanation:
We start by defining
A as event that head was flipped
B1 = event that coin is biased
B2 = event that it is unbiased
P(B1) = 3/5
P(B2) = 2/5
P(A|B1) = 3/4
P(A|B2) = 2/4 = 1/2
When we solve this using bayes theorem we have to find
p(B1|A) = [P(B1) x P(A|B1)]/[P(B1) x P(A|B1) + P(B2) x P(A|B2)
= 0.6 x 0.75 / 0.6 x 0.75 + 0.4x0.5
= 0.45/0.45+0.2
= 0.45/0.65
= 0.6923

70+23x-5+110+14x=360 (please show step bc I need to turn in work-paper) Thank you!
x = 5
explanation
70 + 23x - 5 + 110 + 14x = 360
first you group the like terms
23x + 14x + 70 - 5 + 110 = 360
then combine the like terms
23x + 14x 70 - 5 + 110
37x + 175 = 360
subtract 175 from both sides
175 - 175 = 0 360 - 175 = 185
to get
37x = 185
divide both sides by 37
37x/37 = 0 185/37= 5
which gives you
x = 5

Evaluate b(x)=18−0.5x when x=−2,0, and 5.
hope that helps :))
The value of the function b(x) = 18 - 0.5x when x = -2, 0, and 5 are 19, 18 and 15.5 respectively.
What is equation?A formula known as an equation uses the equals sign to express how two expressions are equal.
Given function is b(x) = 18 - 0.5x
Putting x = (-2) in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(-2)
b(x) = 18 - (-1)
b(x) = 18 + 1
b(x) = 19
Putting x = 0 in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(0)
b(x) = 18
Putting x = 5 in b(x) = 18 - 0.5x
b(x) = 18 - 0.5(5)
b(x) = 18 - 2.5
b(x) = 15.5
Hence, required answers are 19, 18 and 15.5 respectively.

Write the slope-intercept form of the equation of the line through the given point with the
given slope.
through: (-1,0), slope = -2
Answer:
y = -2x - 2
Step-by-step explanation:
Slope intercept form of equation is y = mx + c
c is intercept and m is slope
given that slope is -2
m = -2
thus, equation in slope intercept will be
y = -2x + c
The given line passes through (-1,0)
y = -2x + c
lets substitute y = 0 and x = -1 in the given equation
0 = -2*-1 + c
0 = 2 + c
c = -2
Thus, the complete slope intercept equation after using the value of c as -2
we have
y = -2x - 2 answer

For f (x) =4x+7, find f(4)
Answer:
23
Step-by-step explanation:
If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.
This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.
f(4)=4*4+7
f(4)=16+7
f(4)=23
Answer:
f(4)=23
Step-by-step explanation:
1.f(4)=4(4)+7

A recipe for pasta dough says, “Use 150 grams of flour per large egg.”
How many eggs are needed if 450 grams of flour are used?
Zhang is designing protective packaging. He tests his design by dropping a raw egg protected by his packaging from various heights. He finds that the egg is protected up to a height of 11 meters. Zhang needs to convert the height from meters to yards for his report. Unit of Length Customary System Units Metric System Units 1 inch 2.54 centimeters 1 foot 0.3048 meters 1 mile 1.61 kilometers
Answer: 12.034 yards
Step-by-step explanation:
Given the following :
Height to which egg is protected = 11 meters
Converting this height of 11 meters to yards
Let the height in yards = h
1 meter = 1.094 yards
11 meters = h
(1 * h) = (11 * 1.094)
h = 12.034 yards
Hence, the height in yards to which egg is protected = 12.034 yards

what is the solution to
25+r = -5(2+8r)+6r
Step-by-step explanation:
25+r = -5(2+8r)+6r
25+r= -10-40r+6r
25+r= -10-34r
34r +r = -25-10
35r= -35
r= -35/35
r= -1
Answer:
[tex]\huge\boxed{r=-1}[/tex]
Step-by-step explanation:
To solve for this equation, our goal is to isolate the variable r on one side by reversing the equation.
We have the equation [tex]25 + r = -5(2+8r)+6r[/tex]. Let's simplify it.
Apply the distributive property on the right:
[tex]25 + r = (-5 \cdot 2) + (84 \cdot -5) + 6r\\\\25+r = -10 - 40r + 6r[/tex]
Combine like terms:
[tex]25 + r = -10 - 34r[/tex]
Add 34r to both sides:
[tex]25 + r + 34r = -10 - 34r + 34r\\\\25 + 35r = -10[/tex]
Add 10 to both sides:
[tex]25 + 35r + 10 = -10 + 10\\\\35 + 35r = 0[/tex]
Subtract 35 from both sides:
[tex]35 + 35r - 35 = 0 - 35\\\\35r = -35[/tex]
Divide both sides by 35:
[tex]35r \div 35 = -35 \div 35\\\\r = -1[/tex]

Margaret works at a clothing store today she has only sold only shirts and pants the ratio of the number fours sold to the total number of items sold is 2/5 which model shows ratio ratio
Answer:
Step-by-step explanation:
The one with 2 shirts and 5 pants
The ratio of the two pieces of clothing is displayed as 2:3.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, Margaret is employed by a clothing retailer. She has just sold pants and shirts today. The proportion of shirts sold to all other things sold is 2/5. The model that displays this ratio
The ratio of shirts sold to total garments is 2:5 if the number of shirts sold is 2/5 of the total number of clothes sold.
Additionally, the ratio of sold shirts to sold pants is 2:3, meaning that three pants are sold for every two shirts.
For instance, 9 pairs of pants would be sold if 6 shirts were sold.
Therefore, 2:3 shows the ratio of the pair of pants and shirts.
