Camille has already baked 1 cake, and she can bake 2 cakes with each additional stick of butter she buys. Write an equation that shows the relationship between the number of additional sticks of butter and the number of cakes y
Answer:
1+2x=y
Step-by-step explanation:
X: Number of sticks
Y= number of cakes
There is already one cake, so you must add one to the equation. You multiply x by two since 1 stick of butter (x) makes two cakes.

Answer: To establish the strength of a linear association, first compute the correlation coefficient between the variables involved. The, examine the absolute value of the coefficient. A strong relationship has an absolute value of close to 1 (or approaching 1) while a weak relationship has an absolute value close to 0 (or approaching zero).
The data points will be clustered more tightly around the trend line if there is a weak linear association and less tightly if there is a strong one.

A sel contains eleven elements.
a) How many subsets does it have?
b) How many proper subsets does it have?
Answers:
a) 2048b) 2047=============================================================
Explanation:
If a set has n elements inside it, then it has 2^n different subsets.
Consider a set like {a,b,c}. It has n = 3 elements.
It has 2^n = 2^3 = 8 subsets
Those 8 subsets are...
{a,b,c} ..... any set is a subset of itself{a,b}{a,c}{b,c}{a}{b}{c}{ } .... the empty setAs you can see, each subset consists of items that are selected from the original set {a,b,c}. We can't have any repeat letters.
In that list, items 2 through 4 represent subsets with exactly two things inside it. Items 5 through 7 are known as singletons as they only have one item inside each set. The empty set can be written with the symbol [tex]\varnothing[/tex] or you could have a pair of braces with nothing inside them. The empty set is a subset of any set.
--------------
Note how I included {a,b,c} as a subset. Any set is a subset of itself.
A proper subset will ignore the original set and only look at smaller subsets. If we say B is a proper subset of A, then set B will have fewer items compared to set A. Without the "proper" in there, it's possible that A = B.
So all we've done really is kick out one set which drops 2^n to (2^n)-1 when counting the number of proper subsets. I'm using parenthesis to indicate the "-1" is not part of the exponent. If you wrote this on your paper, then you would likely write [tex]2^{n} - 1[/tex]
--------------
For this problem, n = 11
This means there are 2^n = 2^11 = 2048 subsets and (2^n)-1 = 2048-1 = 2047 proper subsets.
The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.
Here,
A set containing 11 elements.
We have to find number of Subsets and number of Proper subsets.
What is Proper subset of a set?
Set A is considered to be a proper subset of Set B if Set B contains at least one element that is not present in Set A.
Now,
Let a set containing n elements.
then, Number of subsets = [tex]2^{n}[/tex]
And, Number of proper subsets = [tex]2^{n} -1[/tex]
Hence,
A set containing 11 elements.
Number of subsets = [tex]2^{11} = 2,048[/tex]
And, Number of proper subsets = [tex]2^{11} -1 = 2,048 - 1 = 2,047[/tex]
Hence, The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.

Answer:
10.12 as a fraction equals 1012/100
Step-by-step explanation:
To write 10.12 as a fraction you have to write 10.12 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
10.12 = 10.12/1 = 101.2/10 = 1012/100

Given that a x b = 70, work out the value of 3b/a
Answer:
the value of 3b ÷ a is 3 ÷ 70
Step-by-step explanation:
The computation is shown below:
Given that
a × b = 70
So it could be write as
a = 70 ÷ b
And, the value of 3b ÷ a is
= 3b ÷ 70 ÷ b ÷ 1
= 3b ÷ 70b
= 3 ÷ 70
Hence, the value of 3b ÷ a is 3 ÷ 70

[tex]Opposite =- \frac{4}{5}[/tex]
Step-by-step explanation:
Given
[tex]Number = \frac{4}{5}[/tex]
Required
Determine its opposite
To get the opposite of a number, we simply subtract it from 0.
So, we have:
[tex]Opposite =0 - \frac{4}{5}[/tex]
[tex]Opposite =- \frac{4}{5}[/tex]
Hence, the opposite is -4/5
An electronics hobbyist has three electronic parts cabinets with two drawers each.
One cabinet has NPN transistors in each drawer, while a second cabinet has PNP transistors in each drawer. The third cabinet has NPN transistors in one drawer and PNP transistors in the other drawer. The hobbyist selects one cabinet at random and withdraws a transistor from one of the drawers.
a) What is the probability that an NPN transistor will be selected?
b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?
c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?
Answer:
a) 0.5 = 50% probability that an NPN transistor will be selected.
b) 0.3333 = 33.33% probability that it came from the cabinet that contains both types
c) 66.67% probability that it comes from the cabinet that contains only NPN transistors
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a) What is the probability that an NPN transistor will be selected?
1/3 probability that the first cabinet is chosen. This cabinet has two transistors, both of which are NPN, so 100% probability of selecting a NPN transistor.
1/3 probability that the second cabinet is chosen. This cabinet has two transistors, both of which are PNP, so 0% probability of selecting a NPN transistor.
1/3 probability that the second cabinet is chosen. This cabinet has two transistors, one of which is NPN, so 50% probability of selecting a NPN transistor.
So
[tex]p = \frac{1}{3}*1 + \frac{1}{3}*0 + \frac{1}{3}*0.5 = \frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = 0.5[/tex]
0.5 = 50% probability that an NPN transistor will be selected.
b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?
Here we use the conditional probability formula.
Event A: NPN transistor
Event B: From the third cabinet.
50% probability that an NPN transistor will be selected, so [tex]P(A) = 0.5[/tex].
1/6 probability that it is from the third cabinet and NPN, so [tex]P(A \cap B) = \frac{1}{6}[/tex]
The desired probability is:
[tex]P(B|A) = \frac{\frac{1}{6}}{0.5} = 0.3333[/tex]
0.3333 = 33.33% probability that it came from the cabinet that contains both types.
c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?
Either it comes from the cabinet with only NPN transistors, or it comes from the cabinet with both types of transistors. The sum of the probabilities of these outcomes is 100%. So
x + 33.33 = 100
x = 66.67
66.67% probability that it comes from the cabinet that contains only NPN transistors

What is a cyclic quadrilateral?If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral. And the sum of opposite angles of the quadrilateral is 180 degrees.
Quadrilateral EFGH is inscribed in a circle as shown. ∠F = (4x + 10)°, ∠G = (2x - 5)º, and ∠H = (3x - 5)°.
Angles ∠F and ∠H will be supplementary angles. Then the equation is given as,
∠F + ∠H = 180
4x + 10 + 3x - 5 = 180
7x = 175
x = 25
The value of the variable 'x' will be 25. Then the correct option is B.

Write an equation in slope-intercept form for the line that passes through (0, 4) and is parallel to y = 3x - 7
Answer:
Step-by-step explanation:
As the line is parallel to the given equation hence it means there slope will be same,
let Y=mx+ c is our required equation ,
y =3x-7 is given so by comparing we get ,
m =3 ( slope )
Now putt the point (0,4) in required equation to get the value of c,
4 =m(0)+c
c=4
now putt the value of m and c in required equation we get ,
y=3x+4
