A spinner has 14 equal sectors with different letters for each sector, as shown below:
Victoria spins the spinner 18 times, and it stops at the letter 'B' 10 times. If she spins the spinner a 20th time, what is the theoretical probability that this time it will stop at the letter 'B'?
PLZ SHOW WORK
BRAINLIEST PLEASE HELP
Answer:
1/14
Step-by-step explanation:
The sectors labeled are B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.
Total number of sectors = 14.
When Victoria spins the spinner 18 times, and it stops at the letter B 10 times.
When Victoria spins the spinner the theoretical probability that this time it will stop at the letter B = Favourable outcomes ÷total number of outcomes.
Favourable outcomes =1 and Total number of outcomes = 14.
Hence Theoretical Probability = 1 over 14.

A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19. What will be the predicted score for the dependent variable if the independent variable is 608.6?
Answer:
The predicted score for the dependent variable will be of 198,454.4.
Step-by-step explanation:
Equation of a regression line:
The equation of a regression line has the following format:
[tex]y = ax + b[/tex]
In which a is the slope and b is the intercept. x is the independent variable while y is the dependent variable.
A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19.
So [tex]y = 326.07x + 8.19[/tex]
What will be the predicted score for the dependent variable if the independent variable is 608.6?
y when x = 608.6. So
[tex]y = 326.07*608.6 + 8.19 = 198454.4[/tex]
The predicted score for the dependent variable will be of 198,454.4.

Approximately 40% of the calls to an airline reservation phone line result in a reservation being made. (round to three decimal places) Suppose an operator handles 10 calls. What is the probability that none of the 10 calls result in a reservation?
What is the probability that at least one call results in a reservation being made?
Answer:
The probability that none of the 10 calls result in a reservation is 0.60%. In turn, the probability that at least one call results in a reservation being made is 99.40%.
Step-by-step explanation:
Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:
0.6 ^ 10 = X
0.006 = X
0.006 x 100 = 0.60%
Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.
100 - 0.60 = 99.40
In turn, the probability that at least one call results in a reservation being made is 99.40%.
Solve the quadratic equation below
(3x+9)(x−4)=0
Answer:
x = {-3, 4}
Step-by-step explanation:
(3x + 9)(x − 4) = 0
Solution 1
3x + 9 = 0
3x = -9
x = -3
Solution 2
x - 4 = 0
x = 4
x = {-3, 4}
---------------------------
if by solve you meant expand
(3x + 9)(x − 4) = 0
3x² - 12x + 9x - 36 = 0
3x² - 3x - 36 = 0
Answer:
x = 4
x = - 3
Step-by-step explanation:
Method 1
Quadratic Formula
(3x + 9)(x - 4) = 0
3x(x - 4) + 9(x - 4) = 0
3x² - 12x + 9(x - 4) = 0
3x² - 12x + 9x - 36 = 0
3x² - 3x - 36 = 0
3(x² - x - 12) = 0
[tex]\frac{3(x^{2} - x - 12)}{3} = \frac{0}{3}[/tex]
[tex]x={\frac{-b±\sqrt{b^{2}-4ac } }{2a} }[/tex]
Ignore the A after the -b, wouldn't let me type it correctly. Ignore the A for the rest of the explanation as well.
x² - x - 12 = 0
a = 1
b = - 1
c = - 12
[tex]x={\frac{-(-1)±\sqrt{(-1)^{2}-4(1(-12)) } }{2(1)} }[/tex]
[tex]x={\frac{-(-1)±\sqrt{1-4(1(-12)) } }{2(1)} }[/tex]
[tex]x={\frac{-(-1)±\sqrt{1+48 } }{2(1)} }[/tex]
[tex]x={\frac{-(-1)±\sqrt{49 } }{2(1)} }[/tex]
[tex]x={\frac{1±7 }{2(1)} }[/tex]
[tex]x={\frac{1±7 }{2} }[/tex]
Separate into two equations.
One with addition and the other with subtraction.
[tex]x={\frac{1+7 }{2} }[/tex]
[tex]x={\frac{1-7 }{2} }[/tex]
x = 4
x = - 3
Method 2
Factors
(3x + 9)(x - 4) = 0
3x(x - 4) + 9(x - 4) = 0
3x² - 12x + 9(x - 4) = 0
3x² - 12x + 9x - 36 = 0
3x² - 3x - 36 = 0
3(x² - x - 12) = 0
3(x² + 3x - 4x - 12) = 0
3(x² + 3x + (- 4x - 12)) = 0
3(x(x + 3) - 4(x + 3)) = 0
3(x - 4)(x + 3) = 0
Create separate equations
x - 4 = 0
x + 3 = 0
x - 4 = 0 ⇒ x - 4 + 4 = 0 + 4 ⇒ x = 4
x + 3 = 0 ⇒ x + 3 - 3 = 0 - 3 ⇒ x = - 3
x = 4
x = - 3
Solve for
x. Round to the nearest tenth, if necessary.

From a hot-air balloon, Meena measures a 37° angle of depression to a landmark
that's 1865 feet away, measuring horizontally. What's the balloon's vertical distance
above the ground? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
The balloon is 1405.38 feet above the ground.
Step-by-step explanation:
tan 37 = opp/adj = x/1865
tan 37/1 = x/1865
1865 tan 37 = x
x=1405.378303...≈1405.38

Log (14\3) + log(11/5) - log(22/5) = log(?)
Answer:
The answer would be 7
Step-by-step explanation:
The equivalent value of the logarithmic equation is x = 7/3
What is Logarithm?The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
A = log ( 14/3 ) + log ( 11/5 ) - log ( 22/5 )
On simplifying , we get
From the properties of logarithm , we get
log A + log B = log AB
log A − log B = log A/B
So , A = log (14/3) + log (11/5) - log (22/5) = log [(14/3) × (11/5) / (22/5)]
A = log [(14/3) × (11/5) × (5/22)]
A = log ( 14/3 /2 )
A = log ( 7/3 )
Hence , the logarithmic equation is solved

Fred lives way out in the country. He goes shopping only once a year. He bought 500 cans of corn at $0.30 each, 617 pounds of potatoes for $ 0.59 per pound, 379 boxes of Jell-O at $0.98 per box, 116 gallons of milk at $4.25 a gallon, and 2 loaves of bread costing $0.98 each. How much money did Fred spend?
Answer:
Hello there! Mizuki here to help!
The correct answer will be:
Fred is going to spend $1380.41
Step-by-step explanation:
The whole work I did:
500 x 0.3 = 150
617 x 0.59 = 364.03
379 x 0.98 = 371.42
116 x 4.25 = 493
2 x 0.98 = 1.96
150 + 364.03 + 371.42 + 493 + 1.96 = 1380.41
after being discounted 40%, weather radio sells for $35.97. find the original price (round your answer to the nearest cent)
Answer:
$89.93
Step-by-step explanation:
Set up an equation:
Variable x = original price
40/100 = 35.97/x
Cross multiply
40 × x = 100 × 35.97
40x = 3597
Divide both sides by 40
x = 89.925
Round to the nearest cent:
5 rounds up so:
89.93
Check your work (use the original number instead of the rounded number to be more exact):
89.925 × 40%
Convert the percentage into a decimal to multiply:
89.925 × 0.40
35.97

For every unit increase in commute time, well being falls by 0.0635 on average ;
67.1
Step-by-step explanation:
Given :
Commute Time (minutes), x : 5 20 25 35 60 72 105
Well-Being Index Score, y : 69.1 67.8 67.1 66.6 65.0 65.0 62.3
The regression model obtained is :

What is the y- intercept of function f ?
A. -1
B. 1
C. -2
D. 5
Answer:
y intercept = 5
Step-by-step explanation:
f(x)=5•(1/6)^x
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)^0
= 5* 1 = 5
The y intercept is 5
If the question is
f(x)=5•(1/6)x
although I have never seen the question written this way
The y intercept is when x =0
Let x =0
f(0)=5•(1/6)0
= 5* 0 = 0
The y intercept is 0
Answer:
B. 1
Step-by-step explanation:
The y-intercept occurs at x = 0
therefor the applicable function is
f(x) = -x + 1
at x=0
f(0) = -0 + 1
f(0) = 1
