between the time Iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14 °. Write an addition expression for the temperature relative to when Iko woke up.

Answer:

Step-by-step explanation:

41%

(a) P(X = 3) ≈ 0.2687

(b) P(X ≥ 4) ≈ 0.9852

(c) P(X < 8) ≈ 0.9998

These probabilities were calculated using the binomial probability formula for a 41% favorability rate and 12 trials.

To find the probability in this scenario, we can use the binomial probability formula. Let's break down each part of the question:

(a) To find the probability that exactly three out of twelve U.S. adults favor the use of unmanned drones, we can use the binomial probability formula:

P(X = k) = (n choose k) ×[tex]p^k[/tex] ×[tex](1-p)^(n-k)[/tex]

Where:

n is the number of trials (12 in this case).

k is the specific number of successes we're interested in (3 in this case).

p is the probability of success (41% or 0.41 in decimal form).

P(X = 3) = (12 choose 3) × [tex](0.41^3)[/tex] × [tex](0.59^9)[/tex]

Calculate this using a binomial calculator or software to find the exact probability.

(b) To find the probability that at least four out of twelve U.S. adults favor the use of drones, we need to calculate the complementary probability of having fewer than four favoring drones and subtract it from 1:

P(X ≥ 4) = 1 - [P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)]

(c) To find the probability that less than eight out of twelve U.S. adults favor the use of drones, calculate:

P(X < 8) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 7)

You can compute these probabilities using a binomial calculator or statistical software to get the precise answers.

Step-by-step explanation:

Final answer:

The x-intercept of the line 5x - y = 10 is (2, 0), the y-intercept of the line 9x + 3y = -18 is (0, -6), and the equation 6x - 4y = -12 has an x-intercept at (-2, 0) and a y-intercept at (0, 3).

Explanation:

To find the x-intercept of a line, we set the value of y to zero and solve for x. For the equation 5x - y = 10, we set y to 0:

5x - (0) = 10

5x = 10

x = 2

The x-intercept is therefore the point (2, 0).

To find the y-intercept of a line, we set the value of x to zero and solve for y. For the equation 9x + 3y = -18, we set x to 0:

(0) + 3y = -18

3y = -18

y = -6

The y-intercept is therefore the point (0, -6).

For the equation 6x - 4y = -12, the x-intercept and y-intercept can be found similarly. Let's start with the x-intercept. Set y to 0:

6x - (0) = -12

6x = -12

x = -2

The x-intercept is the point (-2, 0). Now, for the y-intercept, we set x to 0:

(0) - 4y = -12

-4y = -12

y = 3

The y-intercept is the point (0, 3). Thus, for 6x - 4y = -12, the intercepts are x = -2 and y = 3.

Answer w/ explanation:

The answer is 9.1

To round to 2 significant figures, we have to find the first significant figure. We find the first sig fig by looking for the first nonzero digit in the number (it can be before or after the decimal point), which is "9"

The next digit is "0". This will also be a significant figure in our answer.

It may seem we are done now since we found the two significant figures. However, let's look at the digit after "0" to see if we need to round up or down.

The digit after "0" is "7". Since 7 is greater than 5, we round up the "0" to a "1" in our final answer, making the answer 9.1

Side note:

The definition and concept of significant figures can be very confusing overall, so please continue to ask questions if you are still struggling with them.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The given decimal number 3.636408 can be written to the nearest ten-thousandth with the help of a number line. The two of the closest number to 3.636408 are 3.636 and 3.637.

Now, as it can be observed that the distance between 3.636408 and 3.636 is less than 3.636408 and 3.637.

Therefore, the number 3.636408 to the nearest ten-thousandth will be 3.636.

1. For every extra copy, Ivanna sells she gets an additional 120 dollars (+$120) and for every less copy she loses $120 dollars (-$120).

2. Ivanna's total pay is $2,400 if she doesn't sell any copies of History is Fun.

Step-by-step explanation:

Step 1:

y = 2,400 + 120x, where y is Ivanna's total pay and x is the number of copies of history is fun she sells.

To calculate the change is Ivanna's pay we find the difference in pay for two consecutive values of y.

We must calculate y when x is of consecutive values i.e. 1, 2, 3, 4 ...

Step 2:

We calculate the value of y when x = 1, 2 and 3.

When x = 1, y = 2,400 + 120 (1) = 2,400 + 120 = $2,520.

When x = 2, y = 2,400 + 120 (2) = 2,400 + 240 = $2,640.

When x = 3, y = 2,400 + 120 (3) = 2,400 + 360 = $2,760.

Step 3:

To calculate the increase in her pay for a copy, we subtract y when x = 2 from y when x = 3.

(y when x = 3) - (y when x = 2) = $2,760 - $2,640 = $120.

So for every extra copy, Ivanna gets an extra $120.

To calculate the decrease in her pay for a copy, we subtract y when x = 3 from y when x = 2.

(y when x = 2) - (y when x = 3) = $2,640 - $2,760 = -$120.

So for every less copy, Ivanna loses $120.

Step 4:

To calculate her pay when she doesn't sell any copies of history is fun, we substitute the value of x as 0 in y.

When x = 0, y = 2,400 + 120 (0) = $2,400.

So Ivanna earns $2,400 if she doesn't sell any copies of history is fun.
