What do large circus animals wear to keep their legs warm worksheet 2.10 answers

docker41 [41]

I bet this question is a science joke. My answer for this would be Elepants. Large circus animals wear elepants to keep their legs warm. People wear pants to keep the bottom parts warm and one of the large animals that we can see in a curcus are elephants. So, yeah, elepants it is.

According to the WHO MONICA Project the mean blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg

Alja [10]

Answer:

a) Let X the random variable that represent the blood pressure for people of a population, and for this case we know the distribution for X is given by:

$X \sim N(128,23)$

Where $\mu=128$ and $\sigma=23$

b) $P(X\geq 135)=P(\frac{X-\mu}{\sigma}\geq \frac{135-\mu}{\sigma})=P(Z\geq \frac{135-128}{23})=P(Z\geq 0.304)$

And we can find this probability using the complement rule:

$P(Z\geq 0.304)=1-P(Z$

And in order to find this probabilities we can use tables for the normal standard distribution, excel or a calculator.

$P(Z\geq 0.304)=1-P(Z$

Step-by-step explanation:

Previous concepts

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 Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the blood pressure for people of a population, and for this case we know the distribution for X is given by:

$X \sim N(128,23)$

Where $\mu=128$ and $\sigma=23$

Part b

We are interested on this probability

$P(X\geq 135)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X\geq 135)=P(\frac{X-\mu}{\sigma}\geq \frac{135-\mu}{\sigma})=P(Z\geq \frac{135-128}{23})=P(Z\geq 0.304)$

And we can find this probability using the complement rule:

$P(Z\geq 0.304)=1-P(Z$

And in order to find this probabilities we can use tables for the normal standard distribution, excel or a calculator.

$P(Z\geq 0.304)=1-P(Z$

Which is the greatest 1/12, 1/32, 1/48 or 1/18

lilavasa [31]

Answer:

$\frac{1}{12}$

Step-by-step explanation:

The number with the smallest denominator is the larger number and $\frac{1}{12}$ is the number with the smallest denominator out of $\frac{1}{12} , \frac{1}{32} , \frac{1}{48} , \frac{1}{18}$ .

Write the quadratic equation whose roots are 1 and -3, and whose leading coefficient is 1.

miss Akunina [59]

Step-by-step explanation:

Factor Theorem:

"If a is a root of a polynomial, (x - a) is a zero of the polynomial."

Therefore by Factor Theorem,

we have (x - 1)(x + 3) = x² + 2x - 3.
