Answer:
C = 0.5t + 12. Independent variable is t and the dependent variable is C.
Step-by-step explanation:
$12 is constant, and then $0.50 is multiplied to the amount of toppings (t). So C= 0.5t + 12 and the cost is dependent on the amount of toppings.
Answer:
C = 0.5t +12
Step-by-step explanation:

This question is incomplete, the complete question is;
According to a recent survey, 73% of all customers will return to the same grocery store. Suppose 14 customers are selected at random, what is the probability that: (Round probabilities to 4 decimal places and the expected customers to 2 decimal places)
a) All 14 will return?
b) How many customers would be expected to return to the store ?
Answer:
a) the probability that All 14 will return is 0.0122
b) The number of customers that would be expected to return to the store is 13.27
Step-by-step explanation:
Given the data in the question;
p = 73% = 0.73
sample size n = 14
a) the probability that All 14 will return;
P( x = 14 ) = ⁿCₓ × Pˣ × [tex]( 1 - P)^{n-x[/tex]
we substitute
P( x = 14 ) = ¹⁴C₁₄ × (0.73)¹⁴ × [tex]( 1 - 0.73)^{(14-14)[/tex]
P( x = 14 ) = [ 14! / ( 14! × ( 14 - 14)!) ] × (0.73)¹⁴ × [tex]( 0.27)^{0[/tex]
P( x = 14 ) = 1 × 0.0122045 × [tex]( 0.27)^{0[/tex]
P( x = 14 ) = 1 × 0.0122045 × 1
P( x = 14 ) = 0.0122045 ≈ 0.0122 { 4 decimal place }
Therefore, the probability that All 14 will return is 0.0122
b) Expected Customers;
E(x) = n × p
we substitute
E(x) = 14 × 0.73
E(x) = 13.27 { 2 decimal place }
Therefore, The number of customers that would be expected to return to the store is 13.27

Answer:
x = 0, x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
8x² - 12x = 0 ← factor out 4x from each term
4x(2x - 3) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
find the vertex of the graph of the following quadratic equations y= -3x^2 -12x-13
Answer:
Step-by-step explanation:
The vertex is a point. The x value is defined as x = - b / 2a where
a = -3
b = - 12
x = - -12/ 2* -3
x = 12 / - 6
x = -2
what is y when x = - 2?
y = -3(-2)^2 - 12(-2) - 13
y = -12 + 24 - 13
y = -1
Does the graph agree? It should
The equation is written as
y = -3(x + 2)^2 - 1

If A = –2p + 7 and B = p2 + 3p – 5, find an expression that equals A – 3B in
standard form.
Answer:
-3p^2 - 11p + 22
Step-by-step explanation:
A - 3B becomes (-2p + 7) - 3*(p^2 + 3p - 5).
Perform the indicated multiplication, obtaining:
(-2p + 7) - 3p^2 - 9p + 15, and then:
-2p + 7 - 3p^2 - 9p + 15, or (combining like terms):
-3p^2 - 11p + 22
One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.
Answer:
[tex]a_{n} = 5 * 3^{n-1}[/tex]
Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:
[tex]a_{1} *r^{n-1}[/tex]
where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 = [tex]a_{1} * 3^{4 - 1}[/tex]
135 = [tex]a_{1} * 3^3[/tex]
135 = [tex]27a_{1}[/tex]
[tex]a_{1} = 5[/tex]
Now, we can substitute the first term back in:
[tex]a_{n} = 5 * 3^{n-1}[/tex]
A tutoring company would like to understand if most students tend to improve their grades (or not) after they use their services. They sample 220 of the students who used their service in the past year and ask them if their grades have improved or declined from the previous year. Write the null and alternative hypotheses in words.
Answer:
Null hypothesis :
Grades have not improved for a majority of students
Alternative hypothesis :
Grades have improved for a majority of students
Step-by-step explanation:
The null and alternative hypothesis for this scenario who see the null hypothesis take a midpoint between improvement and decline ; which can be expressed as ;
H0 : p = 0.5
This means that the performance of students is at a centre point where it could swing either way (decline or improve).
To test of grade has improved students, the, the proportion of f students who have proved should be greater. Which is what the test intends.
H1 : p > 0.5

♡ Firstly , Here are some of the questions & their answers which should be known before simplifying the given expression :
Q. Do I have to change the sign of each term of second expression while subtracting ?
Ans : Yep! While subtracting , sign of each term of the second expression changes whereas In addition , sign of each term in the expressions remains unchanged.
Q. What do you mean by Like terms & Unlike terms ?
Ans : Well , Like terms are those which have the same base whereas Unlike terms are those which have the different base [ For eg : In 4x , 2y , 3x & 4y , 4x & 3x are like terms and 2y and 4y are like terms ]. Also Remember : Only coefficients of like terms can be added or subtracted.

what is the slope of this graph
Answer:
Slope, m = 5
Step-by-step explanation:
Picking points on the x-axis and y-axis of the graph;
Point on x-axis (x1, x2) = 2, 4
Points on the y-axis (y1, y2) = 10, 20
To find the slope;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {20 - 10}{4 - 2} [/tex]
[tex] Slope, m = \frac {10}{2} [/tex]
Slope, m = 5

D. X + 16
E. X + 28
A and e
Step-by-step explanation:
i did this on khan so I know it
The expression (x² + 12x + 32)/(x + 4) is equivalent to (x+8) option (B) (x+8) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
[tex]=\rm \dfrac{x^2 + 12x + 32} { x + 4}[/tex]
[tex]=\rm \dfrac{(x+4)(x+8)} { x + 4}[/tex]
As it is given, x ≠ -4
We can cross the term (x+4) from the numerator and denominator.
= (x+8)
Thus, the expression (x² + 12x + 32)/(x + 4) is equivalent to (x+8) option (B) (x+8) is correct.

When Annie hits a softball, the height of the
ball above the ground after t seconds is given
by h = -4.9/2 + 19.61 + 1.4 metres. Find the
maximum height reached by the ball.
Answer:
21 metres.
Step-by-step explanation:
I think you mean the equation to be:
h = -4.9t^2 + 19.6t + 1.4
To find the maximum height we convert the equation to vertex form:
h = -4.9(t^2 - 4t) + 1.4
h = -4.9[(t - 2)^2 - 4] + 1.4
h = -4.9(t - 2)^2 + 19.6 + 1.4
h = -4.9(t - 2)^2 + 21.
The maximum height is 21 metres.
