Evaluate 15 + |-3| - 4

Answer:

200

Step-by-step explanation:

\(a^{2}\) + \(b^{2}\) = \(c^{2}\)

\(120^{2}\) + \(160^{2}\) = \(c^{2}\)

14400 + 25600 = \(c^{2}\)

40000 = \(c^{2}\)

\(\sqrt{40000}\) = \(\sqrt{c^{2} }\)

200 = c

Answer:

39 ft^2

Step-by-step explanation:

Find the area of the triangle and subtract the area of the square.

area of triangle = bh/2

area of square = s^2

shaded area = bh/2 - s^2

shaded area = (20 ft)(16 ft)/2 - (11 ft)^2

shaded area = 160 ft^2 - 121 ft^2

shaded area = 39 ft^2

Answer:

true

Step-by-step explanation:

f(-2) = 0, meaning that -2 seconds after the object was dropped, the object was 0 feet above the ground. This interpretation makes sense in the context of the problem.

f(0.5) = 100, meaning that 0.5 seconds after the object was dropped, the object was 100 feet above the ground. This interpretation makes sense in the context of the problem.

f(6) = -576, meaning that 6 seconds after the object was dropped, the object was -576 feet above the ground. This interpretation does not make sense in the context of the problem.

Based on the observations above, it is clear that an appropriate domain for the function is [-2, 0.5].

Based on the information provided, the height h (in meters), of this object during its launching with respect to time can be modeled by this quadratic function:

f(x) = -16x² + 16x + 96

when x = -2, the height function is given by:

f(-2) = -16(-2)² + 16(-2) + 96

f(-2) = -64 - 32 + 96

f(-2) = 0.

When x = 0.5, the height function is given by:

f(0.5) = -16(0.5)² + 16(0.5) + 96

f(0.5) = -4 + 8 + 96

f(0.5) = 100 feet.

When x = 6, the height function is given by:

f(6) = -16(6)² + 16(6) + 96

f(6) = -576 + 96 + 96

f(6) = -384.

Both equations are having same slope, Hence they are parallel. Option B.

Proving:-

Let here p = y,

  and x =q

Comparing with y = mx + c

1. 8p = 12 - 2q

 y = 12/8 - 2/8q

   y = - 2/8q + 12/8

slope = -1/4

2. q + 4p = 6

y = mx +c

 4p = - q +6

 p = -1/4q + 6/4

Slope = -1/4

In both equation the slope are same, So thet are parallel.

Answer:

  (b)  22 in

Step-by-step explanation:

You want the perimeter of a rectangle with side lengths 4 inches and 7 inches.

The perimeter of a rectangle is the sum of the lengths of its sides. Your rectangle has two sides that are 4 inches, and two sides that are 7 inches. The perimeter is the sum of these lengths:

  P = 4 in + 4 in + 7 in + 7 in

  P = 22 in

The perimeter of the rectangle is 22 inches.

__

Additional comment

We can save a math operation by recognizing the sum can be arranged to ...

  P = (4 in +7 in) +(4 in +7 in) = 2(4 in +7 in)

This is evaluated using one sum and one product, rather than the three sums we need if we simply add the lengths of the four sides.

This is why the usual formula for the perimeter of a rectangle is ...

  P = 2(L +W)

Answer: Plumber B

Step-by-step explanation:

Plumber A: First, multiply $55 times 4, then add the fee of $40. This will give you $260 as total. This is how much it would cost for Plumber A.

Plumber B: Multiply $40 by 4 and then add $60. This gives you $220, showing that Plumber B is a better option.

Answer:

Plumber B

Step-by-step explanation:

We could set up 2 expressions, and set the time to be 4 hours, and see which plumber costs less:

Plumber A: 40+55*4 = $260

Plumber B: 60+40*4 = $220

Plumber B is cheaper, so therefore he/she is the better option.

Step-by-step explanation:

If we assume that the first card drawn is green and it is replaced before the second draw, then the probability of drawing two green cards in a row is 12/51, or approximately 0.235.

If we assume that the first card drawn is green and it is replaced before the second draw, then we can say that each draw is independent of the other, and the probability of drawing a green card on each draw is the same.

Let's assume that the deck of cards contains 52 cards, with 13 green cards. Since we know that the first card drawn is green, there are now 51 cards left in the deck, with 12 green cards.

The probability of drawing a green card on the second draw is 12/51, since there are 12 green cards left in the deck out of a total of 51 cards.

To find the probability of drawing two green cards in a row, we need to multiply the probability of drawing a green card on the first draw (which we assumed to be 1 since we know the first card is green) by the probability of drawing a green card on the second draw:

P(drawing two green cards) = 1 x 12/51

Simplifying this expression, we get:

P(drawing two green cards) = 12/51

Therefore, the probability of drawing two green cards is approximately 0.235.

Answer:

H0:p= 0.80                 H1: p< 0.80  one tailed test

Step-by-step explanation:

We state the null and alternative hypotheses as that the results are 80 % against the claim that the results are less than 80%.

H0:p= 0.80                 H1: p< 0.80  one tailed test

p2= 0.8 , p1= 74/97= 0.763

q1= 1-0.763= 0.237    q2= 0.2

The level of significance is 0.05 .

The Z∝= ±1.645 for ∝= 0.05

The test statistic used here is

Z= p1-p2/ √pq/n

Putting the values:

Z= 0.763 -0.8 / √ 0.8*0.2/97

z= -0.037/ 0.0406

z= -0.9113

The Z∝ = ±1.645 for ∝= 0.05 for one tailed test.

As the calculated value  does not fall in the critical region  we fail to reject the null hypothesis. There is not sufficient evidence to support  the claim that such polygraph results are correct less than 80% of the time.

Using the normal probability table.

P (Z <  -0.9113)= 1- P(z= 0.9311) = 1- 0.8238= 0.1762

If P- value is smaller than the significance level reject H0.

0.1762> 0.005  Fail to reject H0.

The basic goal of any considerations technique is to assess the probability that a statement is accurate or that a specific incident will occur. Chance can be represented by any number range between 0 and 1, where 0 normally indicates a percentage but 1 typically indicates the level of certainty. An illustration of probability displays how probable it is that a specific event will take place.

The area of the unshaded sector is 325π/9 square units

The value of the angle subtended by the unshaded sector is 130⁰ the value of the angle subtended by the shaded sector is 230⁰.

To find the area of a sector with radius 10 units and angle 230⁰, we can again use the same formula:

Area of sector = (angle/360) x πr^2

Substituting the values given in the formula, we get:

Area of sector = (230/360) x π(10)²

= (23/36) x 100π

= 575π/9 square units

To find the area of a sector with radius 10 units and angle 130⁰, we can use the formula:

Area of sector = (angle/360) x πr^2
