Answer:
33 1/3
Step-by-step explanation:
1. First, you want to make 6 into a fraction with a bottom/denominator of 3 to make adding 6 and 2/3 easier. So, to make 6 into a fraction with a denominator of 3 , you multiply 6 by 3 to get 18. The 18 is the numerator (top of the fraction) and 3 is the denominator (the bottom). So now you have 18/3+2/3 divided by 1/5.
2. Now, add the 18/3 and the 2/3 to get 20/3 divided by 1/5.
3. After this, you want to divide. To divide fractions, you use Keep, Change, Flip (KCF). To do this, keep the 20/3 the same, change the division sign to multiplication, and flip the 1/5 to 5/1. So, now you have 20/3 multiplied by 5/1.
4. Simplify this by multiplying 20 by 5 and 3 by 1 to get 100/3.
5. Now we have to create 100/3 into a mixed number. To do this, we know that 33 multiplied by 3 is 99, which is as close as we can get to 100 without going over. This means that we can make 100/3 into 33 and 1/3.
Hope this helps! :) If you could give me Brainliest that would be super helpful!
The mixed fraction is 33 1/3.
What is mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction.
Given:

Answer: B. M= 6
Step-by-step explanation:
4(6-1)-5=2(6)+3
The first part of the equation, 4(6-1)-5, 6-1 is 5 and then you multiply that 5 by 4 and get 20, and subtract 5 from 20 and get 15. The second part, 2(6)+3, 6 x 2 is 12 and then you add 3 which equals 15. 15=15 so the answer is correct
Evaluate =f(×) r 6x-2 for f (2a-3)
Answer:
[tex] \boxed{\sf f(2a - 3) = 12a - 20} [/tex]
Step-by-step explanation:
Function given:
⇒f(x) = 6x - 2
Substitute 2a - 3 into the function in place of x:
⇒f(2a - 3) = 6(2a - 3) - 2
Expand bracket:
⇒f(2a - 3) = 12a - 18 - 2
Add the like terms:
⇒f(2a - 3) = 12a - 20

Base = 13

usimg trigonometric ratios
cos? = B/h
? = inverse(13/18) = 43.74 = 44°
Step-by-step explanation:
Here, we are given with two sides and the triangle is a right angled triangle. Here, we can use trigonometry to find the missing angle.
Note: Always remember that the perpendicular, base and hypotenuse changes with the reference angle.According to missing angle, cos theta can be used because we are given with base and hypotenuse. No need to find the perpendicular.
[tex] \cos( \theta) = \frac{base}{hypotenuse} \\ [/tex]
[tex] \cos( \theta) = \frac{13}{18} [/tex]
Now for finding the missing angle theta, inverse of cosine will be applied on the other side. Because, inverse of multiplication is division.
[tex] \theta = \cos {}^{ - 1} ( \frac{13}{18} ) [/tex]
[tex] \theta = \cos {}^{ - 1} (0.7222222222) [/tex]

Which statements are true regarding f(x)=10/x+5
? Check all that apply.
The domain of f(x) is (–∞, –5) U (–5, ∞).
The range of f(x) is (–∞, 2) U (2, ∞).
The x-intercept is at (–5, 0).
The y-intercept is (0, 2).
There is a vertical asymptote at x = –5.
The end behavior is x → –∞, f(x) → 0 and x → ∞, f(x) → 0.
For the function [tex]\frac{10}{x + 5}[/tex] , we can say
The domain of f(x) is (–∞, –5) U (–5, ∞).
The y-intercept is (0, 2).
There is a vertical asymptote at x = –5.
The end behavior is x → –∞, f(x) → 0 and x → ∞, f(x) → 0.
What is a function?A mathematical relationship from a set of inputs to a set of outputs is called a function.
What is domain of a function?The domain of a function is the set of all possible inputs for the function.
What is range of a function?The range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs
What is asymptote?An asymptote is a straight line that can be horizontal, vertical or oblique that goes closer and closer to a curve which is the graphic of a given function.
What is intercept?An intercept of any function is a point where the graph of the function crosses, or intercepts, the x-axis or y-axis.To find the x-intercept we need to do y = 0To find the y-intercept, we need to do x = 0How to know the domain of function?The given function is [tex]\frac{10}{x + 5}[/tex]
Now, if x = -5 then the function becomes undefined.
∴ The domain of the function is all real numbers except -5
So, The domain of f(x) is (–∞, –5) U (–5, ∞).
So, option a is correct.
How to know the range of the function?Clearly, the range of the function includes all real numbers
So, option B is wrong
How to find the x-intercept?To find the x-intercept , we will have to solve f(x) = 0, which is not at all possible for this function.
So, option C is wrong
How to find the y-intercept?To find the y-intercept, we need to do x = 0So, putting x = 0 in the function we get f(x) = 2
So, the y- intercept is (0, 2).
So, option D is correct.
How to find vertical asymptote ?To find the vertical asymptote, we need to make the denominator = 0∴ x+ 5 = 0
∴ x = -5
So, there is a vertical asymptote at x = –5.
Hence option E is correct.
How to find the end behavior?We can see,
As x tends to -∞, x + 5 will also tend to -∞We know that a number divided by ∞ or -∞ becomes 0So, as x tends to -∞, f(x) will tend to 0
So, Option F is correct.

F) Would it be unusual for a package to have only brown M&M's? If this were to happen, what would you think is the reason?
Answer:

Step-by-step explanation:
Given the scenario above :
A) State the random variable.
The random variable is the p opoertion of brown M&M's in a milk chocolate packet.
B.) Argue that this is a binomial experiment.
Each trial is independent for a total number of 52 trials with a set probability of success at 0.14
C) probability that 6 M&M's are brown:.
P(x) = nCx * p^x * (1-p)^(n-x)
p = 0.14 ; (1 - p) = 0.86 ; n = 52 ; x = 6
P(x = 6) = 52C6 × 0.14^6 × 0.86^46
= 20358520 × 0.00000752954 × 0.00097035078
= 0.1487
D) P(x =25)
P(x = 25) = 52C25 × 0.14^25 × 0.86^27
= 477551179875952 × 449.987958058*10^(-24) × 0.01703955245
= 0.00000000366

A box of books weighs 4.10 kg for every meter of it's height. Convert this ratio into pounds per foot.
Answer:
The ratio is k = 2.76 pounds / foot
Step-by-step explanation:
From the question we are told that
For 1 m height => 4.10 kg mass
generally 1 meter = 3.28084 feet
Also
1 kg = 2.20462 pound
4.10 kg = x pounds
So
[tex]x = \frac{4.10 * 2.20462}{1 }[/tex]
=> [tex]x = 9.04 \ pounds[/tex]
So
9.04 pounds = 3.28084 feet
z pounds = 1 foot
So
[tex]z = \frac{ 9.04 * 1 }{ 3.28084}[/tex]
=> z = 2.76 pounds
So the ratio is in pounds per foot is
k = 2.76 pounds / foot
