Find the probability of choosing a letter other than the letter E from a bag that contains the fifteen letters of the name DANIEL BERNOULLI. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answer:
The probability of getting a letter which is not E is 13/15.
Step-by-step explanation:
DANIEL BERNOULLI
The total number of elements in sample space = 15
The probability of getting letter E is
= 2/15
The probability of getting a letter which is not E is
[tex]1 - \frac{2}{15}\\\\\frac{13}{15}[/tex]
In 2003, 520,000 acres of farmland in a region were devoted to growing nuts. By 2012 ,the number of acres used to grow nuts had increased 820,000.Find the average rate of change in the number of acres in a region used to grow nuts from 2003 to 2012.
Answer:
Average rate of change = 33,333.33acre per year
Step-by-step explanation:
Given:
Farm land in 2003 = 520,000 acre
Farm land in 2012 = 820,000 acre
Find:
Average rate of change
Computation;
Number of year = 2012 - 2003
Number of year = 9 year
Average rate of change = [Farm land in 2012 - Farm land in 2003] / Number of year
Average rate of change = [820,000 - 520,000] / 9
Average rate of change = [300,000] / 9
Average rate of change = 33,333.33acre per year

from a game that has the following
payout probability distribution:
6 8
10
Payout ($) 0 4
Probability 0.5 0.2 0.15 0.1 0.05
Expected Value = [?]
Round to the nearest hundredth.
Answer:

Step-by-step explanation:
Given that :
Payout(X) : ___ 0 ___ 4 ___ 6 ____ 8 _____ 10
Probability (p(x) 0.5 _ 0.2 __0.15 __0.1 ___ 0.05
Expected value :E(X) = ΣX* p(x)
E(X) = (0*0.5) + (4*0.2) + (6*0.15) + (8*0.1) + (10*0.05)
E(X) = 3
Expected value = 3.00

Answer:
subtractionmultiplicationcombine like termsStep-by-step explanation:
The properties of equality say the value of the variable does not change if the same function is performed on both sides of the equal sign.
a) 4x +7 = 19 ⇒ 4x = 12
The value -7 was added to both sides. Equivalently, 7 was subtracted from both sides. The Subtraction Property of Equality was used.
__
b) 2x/3 = 8 ⇒ 2x = 24
Both sides were multiplied by 3. The Multiplication Property of Equality was used.
__
c) 5x -6 +2x = 22 ⇒ 7x -6 = 22
Terms 5x and 2x were combined and written as 7x. We call this Combine Like Terms.

y adjusted for wind chill (in degrees Fahrenheit, give
formula:
y=-26 + 1.3x
Estimate the actual temperature if the temperature
Fahrenheit.
Answer:
The actual temperature is: -6.92
Step-by-step explanation:
Given
[tex]y = -26 + 1.3x[/tex]
Required
Find x when [tex]y = -35[/tex]
Substitute [tex]y = -35[/tex] in [tex]y = -26 + 1.3x[/tex]
[tex]-35 = -26 + 1.3x[/tex]
Collect like terms
[tex]1.3x = 26 - 35[/tex]
[tex]1.3x = -9[/tex]
Solve for x
[tex]x =-9/1.3[/tex]
[tex]x =-6.92[/tex]

Answer:
The correct option is (A).
Step-by-step explanation:
The given expression is :
[tex]\dfrac{14x^4y^6}{7x^8y^2}[/tex]
The numerator contains 14x⁴y⁶ and the denominator is 7x⁸y².
We can write it as :
[tex]\dfrac{14x^4y^6}{7x^8y^2}=\dfrac{7\times 2\times x^4\times y^2\times y^4}{7x^4\times x^4\times y^2}[/tex]
Canceling the common terms,
[tex]=\dfrac{2y^4}{x^4}[/tex]
So, the correct option is (A).
which of the following is a proportion 4/6 =9/12, 6/9= 8/12, 8/10=6/8 , 3/4=12/15
can someone PLEASE help me solve this equation ? due soon
[tex]\sf{Given : 3tanx + 7 = \dfrac{2}{(1 - sinx)(1 + sinx)}}[/tex]
We know that : (a - b)(a + b) = a² - b²
[tex]\implies \sf{3tanx + 7 = \dfrac{2}{1 - sin^2x}}[/tex]
We know that : 1 - sin²x = cos²x
[tex]\implies \sf{3tanx + 7 = \dfrac{2}{cos^2x}}[/tex]
[tex]\sf{\bigstar \ \ We \ know \ that : \boxed{\sf{\dfrac{1}{cos^2x} = sec^2x}}}[/tex]
[tex]\implies \sf{3tanx + 7 = 2sec^2x}[/tex]
We know that : sec²x = 1 + tan²x
[tex]\implies \sf{3tanx + 7 =2(1 + tan^2x)}[/tex]
[tex]\implies \sf{2 + 2tan^2x - 3 tanx - 7 = 0}[/tex]
[tex]\implies \sf{2tan^2x - 3 tanx - 5 = 0}[/tex]
[tex]\implies \sf{2tan^2x - 5tanx + 2tanx - 5 = 0}[/tex]
[tex]\implies \sf{2tanx(tanx + 1) - 5(tanx + 1) = 0}[/tex]
[tex]\implies \sf{(tanx + 1)(2tanx - 5) = 0}[/tex]
[tex]\implies \sf{tanx = -1 \ (or) \ tanx = \dfrac{5}{2} }[/tex]

describe an experiment to determine convection currents in water
Answer:
When you boil water heat transfer takes place and the heat gets transferred to the water from the stove ( could be considered conduction or radiation), and when the heat is transferred to the water the cold water sinks whereas the hot water rises this rapid movement of convection is called convection currents.

X
x = [?]
Enter the number in decimal form
Answer:
66
Step-by-step explanation:
x / 6 + 4 = 15
To find x ;
Subtrac4 from both sides
x / 6 + 4 - 4 = 15 - 4
x / 6 = 11
Multiply both sides by 6
x / 6 * 6 = 11 * 6
x = 66
Value of x = 66

Luisa is planning a bridal shower for her best friend. At the party, she wants to serve 3 beverages, 3 appetizers, and 3 desserts, but she does not have time to cook. She can choose from 15 bottled drinks, 10 frozen appetizers, and 13 prepared desserts at the supermarket. How many different ways can Luisa pick the food and drinks to serve at the bridal shower
Answer:
Luisa can pick the food and drinks to serve at the bridal shower in 15,615,600 different ways.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
Also
The order in which the food and drinks are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Beverages:
3 from a set of 15. So
[tex]B = C_{15,3} = \frac{15!}{3!12!} = 455[/tex]
Appetizers:
3 from a set of 10. So
[tex]A = C_{10,3} = \frac{10!}{3!7!} = 120[/tex]
Desserts:
3 from a set of 13. So
[tex]D = C_{13,3} = \frac{13!}{3!10!} = 286[/tex]
How many different ways can Luisa pick the food and drinks to serve at the bridal shower?
By the fundamental counting principle, as beverages, appetizers and desserts are independent:
[tex]T = B*A*D = 455*120*286 = 15,615,600[/tex]
Luisa can pick the food and drinks to serve at the bridal shower in 15,615,600 different ways.
