Answer:
A Type I error would occur if there was no evidence of an improvement on the national exam but there really was improvement.
Step-by-step explanation:
A type 1 error simply occurs when we incorrectly reject a true null hypothesis. In the scenario above, An experiment was conducted in other it know if there is sufficient evidence to support a claim that a new teaching method developed improves students score. If this claim is actually true in the real sense. However, after conducting a statistical test, we conuded that there was no sufficient evidence to support her claim of improvement using the new method, hence, the claim was rejected. By rejecting the claim, a true null has been rejected. Hence, a type 1 error has been committed.

C. -2
D. no slope
Answer:
a.0
Step-by-step explanation:
The slope of any horizontal line is 0
Answer:
A, 0
Step-by-step explanation:
The slope of a line is Change in Y / Change in X. This line is parallel to X-axis, meaning the Y will always be the same. This means that the change in y is 0, meaning the slope is 0 / Change in X, which is 0.

The expression below represents the distance between two points on a number line.
|-5 – 4|
Which number line shows the two points?
Answer:
A
Step-by-step explanation:
|-5 - 4|
The expression represents the absolute value of - 5 - 4 ;
-5 - 4 = - 9
|-5-4| = 9
Hence, the distance between the two points is 9.
Hence, the number line which shows the two points is A.
Is the point (4,11) a solution to the following system of equations? How do you know?
y=2x+14
y=3x−5
Which of these equations has NO solution? A. 3 ( 2 x + 7 ) = 6 ( x + 4 ) − 3 B. 3 ( 6 x − 5 ) = 3 ( 6 x − 5 ) + x C. 8 ( x − 3 ) + 14 = 2 ( 4 x + 5 ) D. 13 x − 7 = 12 ( x − 1 ) + x + 5
Answer:
B ig
Step-by-step explanation:
A: 3(2x+7) = 6(X+4) - 3
<=> 6x+ 21 = 6x + 24 - 3 = 6x + 21
<=> 0 = 21 - 21 = 0
B: 3(6x-5)= 3(6x-5)+x
<=> 18x-15= 18x - 15 + x = 19x - 15
<=> 0 = x
C: 8(x-3) + 14= 2(4x+5)
<=> 8x - 24 + 14 = 8x - 10 = 8x + 10
<=> 0 = 0
D: 13x - 7 = 12( x - 1) +x + 5
<=> 13x - 7 = 12x -12 + x + 5 = 13x - 7
<=> 0 = 0
A number,M, is rounded to 1 decimal place. the result is 9.4 complete the error interval for M
Answer:
[tex]9.35 \le M \le 9.45[/tex]
Step-by-step explanation:
Given
[tex]M = 9.4[/tex] to 1 d p
Required
The error interval
The error interval is represented as:
[tex]Lower \le M \le Upper[/tex]
Where
[tex]Lower = M - 0.05[/tex]
[tex]Upper = M + 0.05[/tex]
So, we have:
[tex]Lower = M - 0.05[/tex]
[tex]Lower = 9.4 - 0.05[/tex]
[tex]Lower = 9.35[/tex]
[tex]Upper = M + 0.05[/tex]
[tex]Upper = 9.4 + 0.05[/tex]
[tex]Upper = 9.45[/tex]
Hence, the error interval: [tex]Lower \le M \le Upper[/tex] is:
[tex]9.35 \le M \le 9.45[/tex]

- What is the volume of a square pyramid with height 15m and slant height 17m?
A 85 m2
B 320 m2
C 1280 m2
D 3840 m2
Answer:
c ) 1280 m^3
here,
slant height (s)= 17m
vertical height ( h)= 15m
length (a)= ?
so,
s^2 = (a/2)^2 + h^2
(17)^2 = (a/2)^2 + 15^2
64 = (a/2)^2
8^2= (a/2)^2
8×2 = a so a = 16
Now we know
volume of pyramid
= 1/3 × a^2 × h
= 1/3 × 16^2 × 15
= 1/3 × 256 × 15
= 1280 m^3
Darren brought $34.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1 3 as much as the souvenir, and the souvenir cost 1 2 the cost of the pass. Darren had $1.50 left over after buying these items. What was the cost of each item?
Answer:Cost each item is : Pass = $21 , Souvenir = 2x/3 = $14 , Burger = x/6 =$3.5 .
Step-by-step explanation:
Here we have , Danny brought $43.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1/4 as much as the souvenir, and the souvenir cost 2/3 the cost of the pass. Danny had $4.50 left over after buying these items. We need to find What was the cost of each item . Let's find out:
Let value of pass is x ! So , the souvenir cost 2/3 the cost of the pass i.e.
⇒
Now , The burger was 1/4 as much as the souvenir i.e.
⇒
⇒
Total Cost = $43 , According to question we have following conditions :
⇒
⇒
⇒
⇒
⇒
⇒
Therefore , Cost each item is : Pass = $21 , Souvenir = 2x/3 = $14 , Burger = x/6 =$3.5 .

Two houses on the same side of the street have house numbers that are consecutive
even integers. The sum of the integers is 58. What are the two house numbers?
Answer:
28 and 30
Step-by-step explanation:
'x' = 1st consecutive #
'x+2' = 2nd consecutive #
x + x+2 = 58
2x + 2 = 58
2x = 56
x = 28
x+2 = 30

Answer:
$705.78
Step-by-step explanation:
Put the given numbers in the formula and do the arithmetic.
P = $300, r = 0.13, n = 1, t = 7
__
A = $300.00(1 + 0.13/1)^(1·7)
A = $300·(1.13^7) ≈ $300·2.35260548
A = $705.78
There will be $705.78 in the account after 7 years.
Reggie needs 24 feet of rope to make a tire swing. He has 10 yards of rope. Is this enough for him to make his swing? Explain.
Answer:
8 yards < 10 yards
He has enough.
Step-by-step explanation:
1 yard = 3 feet
y yards = 24 feet
[tex]\frac{1}{3} :\frac{y}{24}[/tex]
y · 3 = 1 · 24
3y = 24
3y ÷ 3 = 24 ÷ 3
y = 8
24 feet = 8 yards
8 yards < 10 yards

what’s the value of x ?
Answer:
x=70
Step-by-step explanation:
Because these angles are on the opposite sides of each other, they have to add up to 180. This will make the equation 2x-5+45=180. Simplify this to get 2x+40=180. Subtract 40 from both sides to get 2x=140. Divide each side by 2 to isolate x. x=140/2. Simplify this to get x=70.
