There are about 30.2 million small businesses in the u.s and about 30,000 other larger businesses. What percent of all businesse

Leni [432]

<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

Find the total amount
Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

$\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990$

Convert to percentage

0.9990 → % = 0.9990 × 100 = 99.90%

Hope this helps,

Suppose f'(7)=9 and g(7)= 5. <br> Find h'(7) where h(x) = 3f(x) + 2g(x) + 7<br><br> h'(7)=???

Ratling [72]

Answer:

The value of h'(7) = 44 .

Step-by-step explanation:

Given:

f'(7)=9 and g(7)= 5

We have to find : h'(7)

Also,

⇔ $h(x) = 3f(x) + 2g(x) + 7$ ...equation (i)

Plugging the value of 'x' = 7 in equation (i) the equation can be re-framed as:

⇔ $h(7) = 3f(7) + 2g(7) + 7$

Now plugging the value of f'=(7)=9 and g(7)=5 in the above equation:

⇔ $h(7) = 3(9) + 2(5) + 7$

⇔ $h(7)=27+10+7$

⇔ $h(7)=44$

So the value of h=(7) = 44 .

A random sample of 500 of these people is drawn, of whom 194 turn out to be currently enrolled in college. Estimate the percenta

Rzqust [24]

Answer:

$0.388 - 2.00\sqrt{\frac{0.388(1-0.388)}{500}}=0.344$

$0.388 + 2.00\sqrt{\frac{0.388(1-0.388)}{500}}=0.432$

The 95.5% confidence interval would be given by (0.344;0.432)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

Solution to the problem

The estimated proportion on this case is given by:

$p = \frac{X}{n}= \frac{194}{500}=0.388$

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95.5% of confidence, our significance level would be given by $\alpha=1-0.955=0.045$ and $\alpha/2 =0.0225$ . And the critical value would be given by:
