Write an equation for this graph

Answer:

Geoffrey incorrectly found the margin of error because he used the wrong sample size.

Please give be brainliest, I really need it.

Geoffrey incorrectly found the margin of error because he used the wrong sample size. Therefore, the correct option is option B.

Measurement Error is the difference between the approximated value and the actual value of an object/quantity. The relative error can be computed in the percent with the help of relative error formula. Errors in measuring instruments occur due to inescapable faults in the measuring instrument and limitations of the human eye.

There are three types of errors in solving mathematics problems, which are factual error, procedural error, and computational error. Geoffrey incorrectly found the margin of error because he used the wrong sample size.

Therefore, the correct option is option B.

Answer:

m∠A = 30°

m∠B = 80°

m∠C = 70°

Step-by-step explanation:

By applying cosine rule in the given triangle,

b² = a² + c² - 2ac[cos(∠B)]

From the given triangle,

a = 14 m

b = 28 m

c = 24 m

(28)² = (14)² + (24)² - 2(14)(24)cos(B)

784 = 196 + 576 - 672cos(∠B)

cos(∠B) = 0.1786

∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]

∠B = 79.71°

∠B = 80°

By applying sine rule in the given triangle,

[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]

[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]

[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]

[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]

sinA = 0.491958

A = 29.47°

A ≈ 30°

By applying triangle sum theorem,

m∠A + m∠B + m∠C = 180°

30° + 80° + m∠C = 180°

m∠C = 70°

Answer:

A) 16/40 or 4/10

B) 1/2

Step-by-step explanation:

Answer:

x = 1/2   y = -5/2

Step-by-step explanation:

Since we already know an equation for y, we just need to plug it into the other equation.

21x - 7(-5x) = 28

21x + 35x = 28

56x = 28

x = 1/2

Now that we know x, we substitute it into the other equation, to find y.

y = -5x

y = -5(1/2)

= -5/2

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

Since there is an absolute value, the answer must be positive. Multiply 2 by 8 since two negatives equal a positive. So, |15-47 + 9 - 8 -17|. Then add and subtract to get the answer. -32 + 9 - 8 -17 = -48. |-48| = 48

Answer: 50

Step-by-step explanation:

Answer:

y = -2x^2 - 4x - 1

Step-by-step explanation:

We can see that the graph passes through (-2, -1), (-1, 1) and (0, -1).

Let's solve

ax^2 + bx + c = y

a(-2)^2 + b(-2) + c = -1

4a - 2b + c = -1

a(-1)^2 + b(-1) + c = 1

a - b + c = 1

a0^2 + b0 + c = -1

c = -1

we got c = -1 so we input it into the other 2

4a - 2b - 1 = -1

4a - 2b = 0

2a - b = 0

2a = b

a - b - 1 = 1

a - b = 2

a = b + 2

Let's input b = 2a

a = 2a + 2

-a = 2

a = -2

b = 2a = 2*(-2) = -4

c = -1

y = -2x^2 - 4x - 1

Answer:

[tex]\sqrt{90}[/tex]

Step-by-step explanation:

Please see the attached image. Using the coordinates of two points, you can find the distance between them using this formula.

[tex]d=\sqrt{(-2-7)^{2}+(-1-(-4)^{2} } =\sqrt{(-9)^{2} +3^{2} } =\sqrt{81+9} =\sqrt{90}[/tex]

Answer:

[tex] \bf \huge ± 5 [/tex]

Step-by-step explanation:

⟼ - x^ 2 - 8 = - 33

step 1 : add 8 to both sides

⟼ − x² − 8 + 8 = − 33 + 8

⟼ - x² = - 25

step 2 : Divide both sides by -1

⟼ - x² / - 1 = - 25 / - 1

⟼ x² = 25

step 3 : take square root

⟼ x² = 25

⟼ x = ± √25

⟼ x = ± 5

∴ x = ± 5.

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed [tex]V_{avg}=10km/h[/tex]

Distance traveled [tex]d=7km[/tex]

Generally the velocity across a distance is mathematically given given as [tex]V=d/t[/tex]

[tex]10=\frac{7}{t}[/tex]

[tex]t=0.7h\\t=42minutes[/tex]

Therefore

7:20-42 minutes =6:38am

The figure.

To find:

The segment bisector of MN and value of MN.

Solution:

From the given figure it is clear that ray RP,i.e.,  is the segment bisector of MN because it divides segment MN in two equal parts.

Answer:

La suma de cifras del producto original es igual a 12.

Step-by-step explanation:

De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:

32x=y+54

Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:

y=23x

Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:

32x=23x+54

32x-23x=54

9x=54

x=54/9

x=6

Finalmente, puedes reemplazar el valor de x en y=23x:

y=23x

y=23*6

y=138

Suma de cifras: 1+3+8 = 12

De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.
