The Nisbets went through the drive through
at the donut shop and spent $10.50 on 2
cups of coffee and 4 donuts. Behind them,
the Roys spent $8.25 on 1 cup of coffee and
5 donuts. What is the cost of one cup of
coffee?
Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25
Below an equation is modeled . What value of x makes this equation true?
A list of 5 numbers is shown below.
0, 3, 7, -6, -12.3
Which set contains all the numbers in the list?
A integers
B whole numbers
C natural numbers
D rational number
Answer:
D. Rational Number
Step-by-step explanation:
Integers are defined as all whole numbers, positive and negative, including 0. Since in the list there is a number that is not whole, A is not the correct answer choice.Whole numbers are all positive numbers (including 0) without decimals or fractions. Since the list has a number that is not a whole number, along with two that are negative, B is also not correct.Natural numbers are all positive numbers (excluding 0) without decimals or fractions. Since there is a 0 in the list, C is not correct.Rational numbers are all numbers that can be simplified into a ratio with 2 integers (i.e. π and e are not rational). Since every number on the list can be put into this category, answer choice D is correct.The random variable X~(30,2^2)
Find p(X<33)
Find p(X>26)
Answer:
i) P(X<33) = 0.9232
ii) P(X>26) = 0.001
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 30
Given that the standard deviation of the Population = 4
Let 'X' be the Normal distribution
Step(ii):-
i)
Given that the random variable X = 33
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-30}{2} = 1.5[/tex] >0
P(X<33) = P( Z<1.5)
= 1- P(Z>1.5)
= 1 - ( 0.5 - A(1.5))
= 0.5 + 0.4232
P(X<33) = 0.9232
Step(iii) :-
Given that the random variable X = 26
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-26}{2} = 3.5[/tex] >0
P(X>26) = P( Z>3.5)
= 0.5 - A(3.5)
= 0.5 - 0.4990
= 0.001
P(X>26) = 0.001

Quadrilateral ABCD is inscribed in a
circle.
What is the measure of angle A?
(x + 15)
Enter your answer in the box
mZA=
Answer:
<A = 133degrees
Step-by-step explanation:
Find the diagram attached
Using the theorem that "the sum of opposite angle of a cyclic quadilateral is 180 degrees, hence;
m<A + m<C = 180
4x+5 + x + 15 = 180
4x+x+5+15 = 180
5x+20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32degrees
Get the measure of angle A
<A = 4x+5
<A = 4(32)+5
<A = 128+5
<A = 133degrees

Y=2write the equation of the line in slope intercept form
Answer:
y = 0x + 2
Step-by-step explanation:
y = 2 is the same as y = 0x + 2. The slope of this line is zero (0) (the line is horizontal).
In slope-intercept form, the equation of this line is y = 0x + 2, which may be left as is or changed to y = 2.

If 2 lines intersect the system is called...
1. independent and inconsistent
2. dependent and consistent
3. independent and consistent
4. dependent and inconsistent
Answer:
3. independent and consistent
Step-by-step explanation:
Intersecting Lines have a single point at which the lines intersect. Therefore the solution to this type of system is called a consistent system. (A type of system of linear equation in two variables.) Therefore, there will be no point that is common to both lines. If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent. When you graph the equations, both equations represent the same line.
Find the interest on $6,000 at 5% for 8 months.
A: $200
B: $2,000
C: $240
D: $2,400
Answer:
A.$200
Step-by-step explanation:
I = PRT/ 100
P = $6000
R = 5%
T = 8 months = 8/12 = 2/3
I = (6000 × 5 × 2/3) /100
I = 20000 / 100
I = $200

If a letter is randomly chosen, what is the probability of choosing the letter A?
Answer:
it depends on how many letters there are to choose from.
Answer:
if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%
Step-by-step explanation:
There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!
Or if you want to be really specific, 1/26 as a percent is 3.8462%.
