Reducing the sample size to one-third, increases the error by √3.

The margin of error is given by:

Step-by-step explanation:

The ball thrown upwards follows a parabolic path

The equation that shows the function rewritten in the form that would be best used to identify the maximum height of the ball is [tex]h(t)=-16(t-1)^2+128[/tex]

The equation is given as:

[tex]h(t)=-16t^2+32t+112[/tex]

Factor out -16

[tex]h(t)=-16(t^2-2t)+112[/tex]

Express the bracket as a perfect square expression

[tex]h(t)=-16(t^2-2t + 1 - 1)+112[/tex]

Factor out -4

[tex]h(t)=-16(t^2-2t + 1)+112 + 16 * 1[/tex]

[tex]h(t)=-16(t^2-2t + 1)+128[/tex]

Express as a perfect square

[tex]h(t)=-16(t-1)^2+128[/tex]

Hence, the equivalent expression is [tex]h(t)=-16(t-1)^2+128[/tex]

Answer:

Step-by-step explanation:

6. x + 21 = 56

→ x = 56 – 21

→ x = 35

7. n – 13 = 8

→ n = 8 + 13

→ n = 21

8. w – 7 =41

→ w = 41 + 7

→ w = 48

9. b + 22 = 89

→ b = 89 – 22

→ b = 67

10. z – 53 = 26

→ z = 26 + 53

→ z = 79

Answer:

6.4% of the lights are faulty

Step-by-step explanation:

Well you can make a proportion out of this question.
so lets do faulty/total

16/250 = x/ 100

Since x/100 is basically finding the percent since percent means out of a hundred.

Cross multiply to solve.

250x= 1600

SOlve for x

X=6.4

6.4 percent of the lights are faulty.

Answer:

[tex]x=3c\sqrt{a} -b^2[/tex]

Step-by-step explanation:

[tex]\sqrt{a} =\dfrac{x+b^2}{3c}[/tex]

Multiply both sides by 3c:

[tex]\implies \sqrt{a} \cdot 3c=\dfrac{(x+b^2) \cdot 3c}{3c}[/tex]

[tex]\implies 3c\sqrt{a} =x+b^2[/tex]

Subtract [tex]b^2[/tex] from both sides:

[tex]\implies 3c\sqrt{a} -b^2=x+b^2-b^2[/tex]

[tex]\implies 3c\sqrt{a}-b^2=x[/tex]

Switch sides:

[tex]\implies x=3c\sqrt{a} -b^2[/tex]

Answer:

30feet= 91.5 centimeters

The total of cm in the 1 yard based upon  30.5 centimeters in a foot will be 91.5 centimeters.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

In another word, multiplication is nothing but changing one value by-product of another value

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given that

1 feet = 30.5 centimeters

Given that

1 yard = 3 feet

Hence 1 yard = 3 × 30.5 centimeter.

1 yard = 91.5 centimeters hence in 1 yard there will be 91.5 centimeters

Answer:

y = - 3x - 2

Step-by-step explanation:

The function is linear and can be expressed in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1-4}{-1-(-2)}[/tex] = [tex]\frac{-3}{-1+2}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then

y = - 3x + c

To find c substitute any ordered pair into the equation

using (0, - 2 ) , then

- 2 = - 3(0) + c = 0 + c ⇒ c = - 2

y = - 3x - 2 ← function rule

Answer:

y = - 3x - 2

12 of $20 and 3 of $50 totally didnt edit it... lolol..

Answer:

12 $20 Bills & 3 $50 Bills

Step-by-step explanation:

Because if the total is $390, Then if you get 10 $20 Bill that would equal $200 Bills and if you get 2 $50 Bills then you would get $100. Add the $200 Bills & the $100 Bills you get $300 Bills.

Then you get 1 $50 Bill and 2 $20 Dollar Bills you get $90 Bills.

Add $300 Bills with $90 Bills and you get $390.

If you add the number of bills handed it would be 15.
