Step-by-step explanation:

1. The variable used to predict another variable is called the dependent variable.

2. The predicted attendance if the temperature is 90 degrees would be 9,750.

3. The computed test statistic, rounded to three decimal places, would be approximately 2.071.

1. The variable used to predict another variable is called the dependent variable. It is the variable that is being predicted or explained by the independent variable.

The variable used to predict another variable is called the dependent variable.

2. The given equation is Attendance = 16,500 - 75 * Temperature.

If Temperature is 90 degrees, we can substitute this value into the equation to find the predicted attendance.

Attendance = 16,500 - 75 * 90

Attendance = 16,500 - 6,750

Attendance = 9,750

Therefore, the predicted attendance if the temperature is 90 degrees would be 9,750.

The predicted attendance if the temperature is 90 degrees would be 9,750.

3. To calculate the test statistic, we need to use the formula:

test statistic = (sample correlation coefficient * sqrt(sample size - 2)) / sqrt(1 - sample correlation coefficient^2)

Given:

Sample size (n) = 25

Sample correlation coefficient (r) = 0.60

Substituting these values into the formula:

test statistic = (0.60 * sqrt(25 - 2)) / sqrt(1 - 0.60^2)

test statistic ≈ (0.60 * sqrt(23)) / sqrt(1 - 0.36)

test statistic ≈ (0.60 * sqrt(23)) / sqrt(0.64)

test statistic ≈ (0.60 * sqrt(23)) / 0.8

test statistic ≈ 1.380 / 0.8

test statistic ≈ 1.725

Rounding to three decimal places, the computed test statistic would be approximately 2.071.

The computed test statistic, rounded to three decimal places, would be approximately 2.071.

The final calculation revealed that the height of the mountain was approximately 350.1 meters.

Back in their workshop, Alex applied the tangent function to find the mountain's height. They knew that tangent is the ratio of the opposite side (the height) to the adjacent side (the horizontal distance). Setting up the equation, they plugged in the known values:

tangent(35 degrees) = height / 500 meters

Using trigonometric tables or a calculator, they found that the tangent of 35 degrees is approximately 0.7002. Now they could solve the equation:

0.7002 = height / 500 meters

To isolate the height, they multiplied both sides of the equation by 500:

0.7002 * 500 meters = height

The final calculation revealed that the height of the mountain was approximately 350.1 meters.

With this crucial information, Alex and Sarah could now design the bridge

The maximum height of the coin is approximately 14.825 meters.

To find the maximum height of the coin, we need to find the vertex of the parabolic function. The x-coordinate of the vertex is given by:

x = -b/2a

where a = -5 and b = 13 are the coefficients of the quadratic function f(x) = -5x^2 + 13x + 6.

Plugging these values into the formula, we get:

x = -13/(2×(-5)) = 13/10

Now we can find the y-coordinate of the vertex by plugging in x = 13/10 into the function:

f(13/10) = -5(13/10)^2 + 13(13/10) + 6

Answer:

B and D are correct.

Step-by-step explanation:

First, we find the length of ALL the sides using the Pythagorean Theorem.

16² + b² = 20²

256 + b² = 400

b² = 144

\(\sqrt{144}\) = 12

Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.

A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.

Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.

Answer:

The answer is B and D.

Step-by-step explanation:

Length of ladder AC = 20 feet

Height of the highest point of the ladder from ground AB = 16 ft

By Pythagoras theorem,

AC² = BC² + AB²

BC² = AC² - AB²

BC = √(20)^2-(16)^2

     = √400-256

     = √144

     = 12

Now, Sinθ = opposite side/hypotenuse = AB/AC

                 = 16/20

Cosθ = adjacent side/hypotenuse = BC/AC

         = 12/20

Therefore, A and D are the correct options.

The probability that the plant died because the neighbor forgot to water it is (1 - q) x (1 - %).

Let p = the probability that the plant will die without water, q = the probability that the plant will die with water, and r = the probability that the neighbor will remember to water the plant.

The probability that the plant died because the neighbor forgot to water it is equal to the probability that the plant would have survived had the neighbor remembered to water it, multiplied by the probability that the neighbor did not remember to water it.

P(plant died due to neighbor not watering) = P(plant survived with neighbor watering) x P(neighbor not remembering)

= (1 - q) x (1 - r)

= (1 - q) x (1 - % certain the neighbor will remember)

= (1 - q) x (1 - % certain)

= (1 - q) x (1 - %)

Therefore, the probability that the plant died because the neighbor forgot to water it is (1 - q) x (1 - %).

For the probability distribution the mean of the random variable X is 5.258 this means that, on average, the crew size of a randomly selected shuttle mission is approximately 5.258.

To find the mean of the random variable X, we multiply each value of X by its corresponding probability and sum them up. Let's calculate it step by step:

x | P(X = x)

2 | 0.064

3 | 0.015

4 | 0.055

5 | 0.276

6 | 0.124

7 | 0.387

8 | 0.079

Step 1: Multiply each value of X by its corresponding probability.

2 × 0.064 = 0.128

3 × 0.015 = 0.045

4 × 0.055 = 0.22

5 × 0.276 = 1.38

6 × 0.124 = 0.744

7 × 0.387 = 2.709

8 × 0.079 = 0.632

Step 2: Sum up the products from Step 1.

0.128 + 0.045 + 0.22 + 1.38 + 0.744 + 2.709 + 0.632 = 5.258

2x + 4y = 13

Solving

2x + 4y = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

2x + 4y + -4y = 13 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 13 + -4y

2x = 13 + -4y

Divide each side by '2'.

x = 6.5 + -2y

The formula to calculate the number of bit strings of length six or less, not counting the empty string, is (Σ6i=0 2i) - 1.

To explain this formula, let's break it down. The Σ6i=0 represents a summation from i=0 to i=6. The 2i represents the number of possibilities for each bit (either 0 or 1) and the summation allows us to count all possible combinations of bit strings of length 6 or less.

However, we need to subtract 1 from the total because we are not counting the empty string. This formula ensures that we are only counting bit strings with at least one bit set to either 0 or 1.

In simpler terms, the formula tells us to take 2 to the power of each possible bit position (from 0 to 6), add up all those possibilities, and then subtract 1 to account for the empty string. This gives us the total number of possible bit strings of length six or less.

V: (4, -2), min, Axis: x = 4, Roots 2 and 6

Step-by-step explanation:

Multiply everything x 2 to get rid of the decimal in front of x^2

2y = x^2 - 8x + 12

Factor

2y = (x - 6)(x - 2)

The roots are at 2 and 6.

The axis of symmetry is in the center between the roots, so it is x = 4.

Put 4 into the original equation to find y

y = 0.5(4*2) - 4(4) + 6

y = 8 - 16 + 6, y = -2  

Vertex is at (4, -2). It is a minimum because the graph opens up since x*2 is positive.
