Step-by-step explanation:
Matt thinks that he has a special relationship with the number 2. In particular, Matt thinks that he would roll a 2 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Matt will roll a 2.
(a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "<", ">", "=", "not =" and express any values as a fraction e.g. p = 1/3)
H0 =
Ha =
(b) Now suppose Matt makes n = 46 rolls, and a 2 comes up 10 times out of the 46 rolls. Determine the P-value of the test:
P-value = ( u figure it out) u got it
On the refrigerator, MATHCOUNTS is spelled out with 10 magnets, one letter per magnet. Two vowels and three consonants fall off and are put away in a bag. If the Ts are indistinguishable, how many distinct possible collections of letters could be put in the bag?
Answer:
630 distinct possible collections of letters could be put in the bag.
Step-by-step explanation:
Since on the refrigerator, MATHCOUNTS is spelled out with 10 magnets, one letter per magnet, and two vowels and three consonants fall off and are put away in a bag, if the Ts are indistinguishable, to determine how many distinct possible collections of letters could be put in the bag, the following calculation must be performed:
Vowels: 3
(AO, AU, OU)
Consonants: 7
3 x 7 x 6 x 5 = X
3 x 210 = X
630 = X
Therefore, 630 distinct possible collections of letters could be put in the bag.
Answer: 75 distinct possible collections
Step-by-step explanation:
2 vowels = 3C2 = 3
3 vowels = 25 ways
25 * 3 = 75 total ways

the given figure is rectangle
area of rectangle=l*b
=5*6
=30 ft^2
Answer:
Area = 30 ft²
Step-by-step explanation:
This figure is a rectangle, therefore;
Area of a rectangle = B*W
A = 5*6
A = 30
Therefore the area of the given rectangle is 30 ft²

To which graph does the point (2, 4) belong? (1 point) y ≥ x + 3 y ≥ −x + 8 y ≥ 4x − 5 y ≥ −2x + 9
Answer:
y ≥ 4x − 5
Step-by-step explanation:
using the point (2,4)
when x = 2 then y =4
y ≥ 4x − 5
4 ≥ 4(2) - 5
4 ≥ 8 - 5
4 ≥ 3

A cuboid with a volume of 924 cm^3 has dimensions
4 cm, (x + 1) cm and (x + 11) cm.
Find the longest length of the Cuboid.
Answer:
21
Step-by-step explanation:
Volume of a cuboid is given by
V = l*w*h
924 = 4 (x+1) (x+11)
FOIL
924 = 4(x^2 +11x+x+11)
924 = 4(x^2+12x+11)
Divide each side by 4
231 = (x^2+12x+11)
Subtract 231 from each side
0 = x^2 +12x +11-231
0 = x^2 +12x - 220
Factor
0 = (x+22) (x-10)
Using the zero product property
x+22 =0 x-10 =0
x=-22 x=10
We cannot have a negative length
x=10
The side lengths are 4, 10+1, 10+11
4,11,21
The longest is 21

Answer:
See Explanation
Step-by-step explanation:
Given
The three equations
Required
Label the x and y-axes
The general rule is to place the independent variable (x) on the x-axis and the dependent (y) on the y-axis.
What x and y represented are always stated after writing the equation.
So, we have:
[tex](a)\ y = x + 5[/tex]
[tex]x \to[/tex] Number of chores
[tex]y \to[/tex]Amount
[tex](b)\ y =15x[/tex]
[tex]x \to[/tex] Time (hours)
[tex]y \to[/tex]Miles traveled
[tex](c)\ y = 6x[/tex]
[tex]x \to[/tex] Time (hours)
[tex]y \to[/tex]Miles traveled

Please show work. What is the volume of the figure?
Answer:
Volume = 288 in.³
Step-by-step explanation:
Volume of the solid = volume of the cube + volume of the square pyramid
V = a³ + ⅓*a²*h
a = 6 in.
h = 12 - 6 = 6 in.
Plug in the values into the volume formula
Volume = 6³ + ⅓*6²*6
Volume = 216 + 72
Volume = 288 in.³
Which equation represents a function of x that is not linear?
Answer:
y = 4x+3x^2
Step-by-step explanation:
For an equation to be linear, x must have a power of 1
y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)

Answer:
[tex]\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0[/tex]
Step-by-step explanation:
In any right triangle, the following is true:
The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)
The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)
Thus,
[tex]\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},[/tex]
[tex]\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}[/tex]

PLEASE HELP 15 POINTS,
It is now time to complete the Utilities Discussion. Research the cost of some sort of household bill. Examples are natural gas, electricity, water, etc. Find one that models a linear function and write a function to represent the cost of this utility.
Explain how you found your information and wrote your function. Be sure to define your variables, use function notation.
Step-by-step explanation:
I take gas consumption as example.
Consider the followings,
Let M be the gas meter reading per month
A be the fuel adjustment fee
B be monthly maintenance fee
Y be unit cost per Joule
Let X be monthly bill
( 1 meter reading unit = 48 unit of Joule )
Monthly bill payment :
X = Mx48xY + A + B
in function notation, the monthly bill is f(M, Y, A, C)
