Mathematics
1 answer:
Mashutka [201]3 years ago
5 0

Answer:

5. D

6. I think D. Because is y=mx+b and b is y the intercept in y. Y= 0-4 and replacing the -4 would remain at the end

The graph compares distance in yards and distance in feet.
Zielflug [23.3K]

Answer:

yards = \frac{1}{3} feet

Step-by-step explanation:

The graph is a straight line passing through the origin with equation

y = mx ( m is the slope )

Calculate slope using gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 2) ← 2 points on the line

m = \frac{2-0}{6-0} = \frac{2}{6} = \frac{1}{3}


the x- axis is feet and the y-axis is yards, hence

yards = \frac{1}{3} feet

What’s a mean,median,and mode?
tamaranim1 [39]

The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. Mode is the number which appears most often in a set of numbers.

Hope this helps you :)

The average maximum monthly temperature in Campinas, Brazil is 29.9 degrees Celsius. The standard deviation in maximum monthly t
kvv77 [185]

Answer:

P(X>32)=P(\frac{X-\mu}{\sigma}>\frac{32-\mu}{\sigma})=P(Z>\frac{32-29.9}{2.31})=P(z>0.909)

And we can find this probability with the complement rule and using the normal standard distributon table or excel we got:

P(z>0.909)=1-P(z

And if we convert this to a % we got 18.2 % of maximum temperatures higher or equal than 32 C

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".  

Solution to the problem

Let X the random variable that represent the maximum monthly temperature of a population, and for this case we know the distribution for X is given by:

X \sim N(29.9,2.31)  

Where \mu=29.9 and \sigma=2.31

We are interested on this probability

P(X>32)

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>32)=P(\frac{X-\mu}{\sigma}>\frac{32-\mu}{\sigma})=P(Z>\frac{32-29.9}{2.31})=P(z>0.909)

And we can find this probability with the complement rule and using the normal standard distributon table or excel we got:

P(z>0.909)=1-P(z

And if we convert this to a % we got 18.2 % of maximum temperatures higher or equal than 32 C
