The number of violent crimes committed in a day possesses a distribution with a mean of 2.2 crimes per day and a standard deviat

VARVARA [1.3K]

Answer:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And replacing we got:

$\mu_{\bar X}= 2.2$

$\sigma_{\bar X}= \frac{6}{\sqrt{100}}= 0.6$

Step-by-step explanation:

For this case we have the following info given:

$\mu = 2.2$ represent the mean

$\sigma = 6$ represent the deviation

We select a sample size of n=100. This sample is >30 so then we can use the central limit theorem. And we want to find the distribution for the sample mean and we know that the distribution is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And replacing we got:

$\mu_{\bar X}= 2.2$

$\sigma_{\bar X}= \frac{6}{\sqrt{100}}= 0.6$

Step-by-step explanation:

Given : The recommended daily allowance for vitamin c is 60 mg per day .

Then, for one whole week , the recommended allowance for vitamin c will be :-

$7\times60=420\text{ mg}$

Also, there are 70 mg of vitamin C per 100 g orange.

1 g = 1000 ml

The proportion of Vitamin C in 100 g = $\dfrac{70}{100000}=0.0007$

1 oz =28.3495 grams

Then, $3\ oz= 3\times28.3495=85.0485 \text{ gm}=85048.5\ mg$

Then, amount of vitamin C in 85048.5 mg = $0.0007\times85048.5=59.53395\approx59.53\ mg$

Then, the number of oranges have to eat each week to meet this requirement= $\dfrac{420}{59.53}\approx7$

Hence, about 7 oranges you would have to eat each week to meet this requirement.

Pete asks Buzz to make a triangular truss with sides that are 5 feet, 6 feet, and 9 feet. Is this enough information for Buzz to

Georgia [21]

Answer: Yes.

Step-by-step explanation:

One of the criteria of congruence for triangles is SSS, this means that when we know that two triangles have all the same side lengths, the triangles are congruent. This would mean that all the triangles with the same side lengths are rotations or translations of the same triangle.

Then, when we know the measures of the 3 sides of a triangle, we have only one possible triangle to make, which would mean that Buzz has enough information to make a truss with the correct size and shape.

The points G(1, 4) and H(3, 0) are on a coordinate plane. What is the approximate distance between points G and H?

oksano4ka [1.4K]

Then the approximate distance between the points is 4.47 units.

<h3>What is the approximate distance between points G and H?</h3>

We have the points G(1, 4) and H(3, 0), to get the distance between them we use the distance formula, we will get:

$D = \sqrt{(1 - 3)^2 + (4 - 0)^2} \\\\D = \sqrt{(-2)^2 + (4)^2}\\\\D = \sqrt{4 + 16} = \sqrt{20}$

And we know that √20 ≈ 4.47

Then the approximate distance is 4.47 units.
