Answer:

A

Step-by-step explanation:

A, because it has two points which have the same x-value but different y-values, so it cannot be a function.

Answer:

so the answer is about 8.40

Steps

--------------------------------------------------------------------------------------------------------------

find the number in the tenth place and look one place to the right for the rounding digit. Round up if the number is greater than or equal to 5 but since 2 is less than 5, stays the same

16.820⇒16.82

--------------------------------------------------------------------------------------------------------------

8.264⇒8.364

Remember round up if the number is greater than or equal to 5 and round down if the number is less than 5.

--------------------------------------------------------------------------------------------------------------

now that we have rounded everything. It is time to estimate 16.82-8.364.

16.82 is close to 16.80 and 8.364 is close to 8.40.

16.80-8.40=8.40

Respuesta:

A = 51,167

b = 28,5 pies

c = 45,4 pies

Explicación paso a paso:

C = 90 °

B = 38 ° 50 '

Convertir B a grado

1 ° = 60 '

x ° = 50 '

Multiplicar en cruz:

60x = 50

x = 50/60

x = 0,83333 °

Por lo tanto, 38 ° 50 '= 38 ° + 0.833 ° = 38.833 °

Recordar :

A + B + C = 180 ° (Suma de ángulos en un triángulo)

A + 38.833 + 90 = 180

A + 128.833 = 180

A = 180 - 128,833

A = 51,167 °

Usando identidades trigonométricas, podríamos encontrar byc

Para obtener b:

Tan B = opuesto / adyacente = b / 35.4

Tan 38,833 = b / 35,4

b = Tan 38,833 * 35,4

b = 28,5 pies

Para obtener c:

Podríamos usar:

Sin A = opuesto / hipoteno = 35,4 / c

Sin 51,167 = 35,4 / c

c * sin 51,167 = 35,4

c = 35,4 / sen 51,167

c = 45,4 pies

Answer:

The estimated number of children who attended the parade is 6,336.

Step-by-step explanation:

Since the route for Millburn's Fourth of July parade stretches 2 miles (10,560 feet), and spectators are usually evenly distributed along both sides of the route, and along one side of 50 feet of the route, you count 15 children, to estimate the number of children who attended the parade, the following calculation must be performed:

(10,560 / 50) = 211.2

211.2 x 15 x 2 = X

211.2 x 30 = X

6.336 = X

Therefore, the estimated number of children who attended the parade is 6,336.

Cuboid. A cuboid is a solid that has six rectangular faces--think of a typical box. All faces are either parallel or perpendicular to each other. Further, a cuboid is a right rectangular prism.

Answer:

There are 6 faces in cuboid

Answer:

You are right. It's 56

Step-by-step explanation:

You do half of the solid (4*7) with is 28. Then because it is only half you would double your answer to get 56.

V = L * W

V = 4 * 7

V = 28

Then double it.  28 * 2 = 56

Answer:

x= -1 y= -5

There for: (x, y). (-1,-5).

Step-by-step explanation:

Step one:

y=y

5x=9x+4

5x-9x=4

-4x=4

x= -1

Step two:

y=5x

y= 5(-1)

y= -5

Hope u find this helpful

Step-by-step explanation:

y=5x

y=9x+4

Substituting value of x in equation 2

y=9x+4

5x=9x+4

5x-9x=4

-4x=4

so x = -1

again

y=5x

y=5 * (-1)

so y = -5.

Answer:

1. x = 67.5

2. x = 2.5

3. x = 35.2

4. x = 2.0

5. x = 17.0

Step-by-step explanation:

Question 1

The proportion is set up in the form x/9 = 15/2. Multiply both sides by two to get rid of the two in the denominator on the right side. After doing so, multiply by 9 on both sides to get rid of the 9 in the denominator on the left:

2x/9 = 15

2x = 9(15)

Next solve for x:

2x = 135

x = 67.5

Question 2

The proportion is set up in the form 20/8.7 = 5.8/x. Multiply both sides by the second denominator, x, and then both sides by the first, 8.7. This will leave you with the work below:

20x/8.7 = 5.8

20x = 8.7(5.8)

Next, solve for x:

20x = 50.46

x = 2.523

Round to the nearest tenth:

x = 2.5

Question 3

The proportion is set up in the form 5/16 = 11/x. Multiply both sides by the second denominator, x, and then both sides by the first, 16. This will leave you with the work below:

5x/16 = 11

5x = 11(16)

Next, solve for x:

5x = 176

x = 35.2

Question 4

The proportion is set up in the form x/0.06 = 17/0.5. Multiply both sides by the second denominator, 0.5, and then both sides by the first, 0.06. This will leave you with the work below:

0.5x/0.06 = 17

0.5x = 17(0.06)

Next, solve for x:

0.5x = 1.02

x = 2.04

Round to the nearest tenth:

x = 2.0

Question 5

The proportion is set up in the form 29/x = 75/44. Multiply both sides by the second denominator, 44, and then both sides by the first, x. This will leave you with the work below:

29(44)/x = 75

29(44) = 75x

Next, solve for x:

1276 = 75x

x = 17.0133

Round to the nearest tenth:

x = 17.0

Answer:

B

Step-by-step explanation:

It's kind of ahrd to see but you can see that the x coordinate is for sure 4

b is the only possible answer

Answer:

Part A;

The null hypothesis, H₀, is that the weight loss obtained in the new program is less than or equal to the weight loss obtained in the original program

The alternative hypothesis, Hₐ, is that the weight loss obtained in the new program is more than the weight loss obtained in the original program

Part B;

There is not evidence to suggest that the new program results in an improvement in the percentage of its participants that had weight loss

Step-by-step explanation:

Part A

The participants of the weight loss center that, p₀ = 72% = 0.72

The belief of the center's doctor is that the percentage is not sufficient for the proportion of people losing weight

The number of subjects in the sample the center's doctor used for the test, n = 140

The weight loss percent of the sample using the new program, [tex]\hat p[/tex] = 78% = 0.78

The null hypothesis, H₀;  [tex]\hat p[/tex] ≤ p₀

The alternative hypothesis, Hₐ; [tex]\hat p[/tex] > p₀

Part B

The z-test is given as follows;

[tex]z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0 \cdot (1 - p_0)}{n}}}[/tex]

[tex]\therefore z=\dfrac{0.78-0.72}{\sqrt{\dfrac{0.72 \cdot (1 - 0.72)}{140}}} = 1.53113883009 \approx 1.531[/tex]

The p-value = P(Z ≥ 1.531) = 1 - P(Z ≤ 1.531) = 1 - 0.93699 = 0.06301

Given that the p-value = 0.06301 is larger than the significance level of 0.05, we fail to reject the null

Therefore, there is not enough evidence to suggest that the mean of the weight loss of participants in the new method is more than the weight loss percentage obtained from the original weight loss program.
