Flauer [41]

Answer:

A) 96 + x ≤ 149

Step-by-step explanation:

The airplane can hold 149 passengers.

There are already 96 passengers on board.

They can add x additional passengers, as long as they bring the total to no more than 149.

The inequality is

Answer:

The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

75% of teenagers in North America are pursuing a goal they have set for themselves.

This means that $p = 0.75$

Sample of 200.

This means that $n = 200$ .

What are the mean and standard deviation of the sampling distribution of p?

By the Central Limit Theorem

Mean $\mu = p = 0.75$

Standard deviation $s = \sqrt{\frac{0.75*0.25}{200}} = 0.0306$

The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.

Plastic cups comes in an 10-pack, but paper plates come in a 12 pack. What is the smallest number of plastic cups and paper plat

Andrei [34K]

The answer is 60. You can find this out by finding the least common multiple of 10 and 12, which is 60 because 10x6=60 and 12x5=60. Hope this helps :)

Given that f(1)=2 and f'(1)=4, find the derivative of f(x)loge(x) when x=1

inessss [21]

Answer:

Step-by-step explanation:

loge(x) is ln(x)

f(x) × ln(x)

Differentiate using product law

[ln(x) × f'(x)] + [(1/x) × f(x)]

x = 1

[ln(1) × f'(1)] + [(1/1) × f(1)]

(0 × 4) + (1 × 2)

0 + 2
