State the null and alternative hypothesis: The average score of 40 high school basketball games is less than 26
Answer:
[tex]H_o:\mu = 26[/tex]
[tex]H_a:\mu < 26[/tex]
Step-by-step explanation:
Given
Average score is less than 26
Required
Determine the null and alternate hypothesis
Since the average is said to be less than 26; that represents the alternate hypothesis.
The null hypothesis will be:
[tex]Average = 26[/tex]
So, we have:
[tex]H_o:\mu = 26[/tex]
And the alternate hypothesis
[tex]H_a:\mu < 26[/tex]

Find the missing angle.
(137°
102°
?
Answer:
66°
I hope it helps.........
The missing angle ∠ABC is 35°.
Let the missing angle be x and y To find the missing angle y, we need to solve the equation 102° + x + y = 180, where x and y are angles.
Given that x + 137 = 180, we can substitute the value of x in terms of 180 - 137:
x = 180 - 137
x = 43°
Now, we can substitute the value of x into the equation y =∠ABC
102° + x + y = 180
102° + 43° + y = 180
Combining like terms:
145° + y = 180
To find y, we subtract 145° from both sides:
y = 180 - 145
y = 35°
Therefore, the missing angle ∠ABC is 35°.

A plane flies 1.6 hours at 150 mph on a bearing of 10°. It then turns and flies 9.1 hours at the same speed on a
bearing of 100°. How far is the plane from its starting point?
9514 1404 393
Answer:
1386 miles
Step-by-step explanation:
The plane flies ...
(150 mi/h)(1.6 h) = 240 mi
on its first leg. Then it flies ...
(150 mi/h)(9.1 h) = 1365 mi
on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.
c² = 240² +1395² = 1920825
c = √1920825 ≈ 1385.94
The plane is about 1386 miles from its starting point.

A circle has a radius of 48 millimeters.
What is the length of the arc intercepted by a central angle that measures 3π/4 radians?
Express the answer in terms of π .
Answer:
36π mm
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle (in radians).
If r = 48 mm and Ф = 3π/4, then the arc length is:
s = rФ = (48 mm)(3π/4) = 36π mm
Answer:
36π

Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10
___________________________________________
Hope that helped. Good luck.
Answer:
7.) y=8, x=7
8.) y=3, x=11
9.) h=65, k=10
Step-by-step explanation:
First, let's start with #7. By definition of a parallelogram, we can say that opposite sides are congruent, meaning 2y-7=9 and 3x+2=23.
So, solving these problems-
2y-7=9
2y=16
y=8
3x+2=23
3x=21
x=7
Now, let's move on to #8. For this, a defining property of a parallelogram is that the diagonals bisect each other. So, 3y+5=14 and 2x-5=17.
Let's solve these equations-
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
Now, finally #9. Another defining property of a parallelogram is that opposite angles are congruent. So, 2h=130 and 5k=50.
So, h= 65 and k= 10.

The state fair is a popular field trip destination. This year the senior class at High School A and he senior class at High School B both planned trips there. The senior class at High School A rented and filled 2 vans and 5 buses with 307 students. High School B rented and filled 6 vans and 10 buses with 626 students. Each van and each bus carried the same number of students.Find the number of students in each van and in each bus.
Let x = number of students in each van
y = number of tudents in each bus
Equation 1: 2x+5y=307
Equation 2: 6x+10y=626
Part A: Which method will you use to solve this problem? (Graphing (Rewrite equations in slope intercept form first), Substitution, or elimination) ATTACH YOUR WORK
Part B: How many students can a van carry?
How many students can a bus carry?
Answer:
Use elimination, x = 6, y = 59
Step-by-step explanation:
1) Multiply Equation 1 by 2
E1: 4x +10y = 614
E2: 6x+10y = 626
2) Subtract E2 from E1
-2x = -12
x = 6
3) Substitute x = 6 into one of the equations (I used the original Equation 1)
2(6) +5y = 307
12+ 5y = 307
5y = 295
y = 59
A van can carry 6 students, and a bus can carry 59 students.

Which equation is graphed along with the parent function?

g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4
g(x) = RootIndex 3 StartRoot x minus 4 EndRoot + 3
g(x) = RootIndex 3 StartRoot x + 4 EndRoot + 3
Answer:
B. g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4
Step-by-step explanation:
edg 2021 .. its correct
The equation that is graphed along with the parent function is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]
The parent function is a cube root function, represented as:
[tex]f(x) = \sqrt[3]{x}[/tex]
First, the parent function is horizontally shifted right by 3 units
The rule of this transformation is:
[tex](x,y) \to (x - 3,y)[/tex]
So, we have:
[tex]f'(x) = \sqrt[3]{x - 3}[/tex]
Next, the transformed function is vertically shifted up by 4 units
The rule of this transformation is:
[tex](x,y) \to (x,y+4)[/tex]
So, we have:
[tex]g(x)=\sqrt[3]{x-3} +4[/tex]
Hence, the equation is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]
