Given the lengths of the sides, state if the triangle is acute, obtuse, or right. 8, 15, and 17 This is a(n) blank triangle.

Ivahew [28]

Answer:

This is a right triangle

Step-by-step explanation:

Pythagoras theorem is used to determine if a triangle is right, acute or obtuse

If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.

If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.

If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.

so,

$(17)^2 = (15)^2+(8)^2\\289 = 225+64\\289=289$

Therefore, the given triangle is a right triangle ..

The mean percent of childhood asthma prevalence in 43 cities is 2.32%. A random sample of 32 of these cities is selected. What

lidiya [134]

Answer:

$P(\bar X>2.8)$

We can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{2.8 -2.32}{\frac{1.24}{\sqrt{32}}}=2.190$

And using the normal standard distribution and the complement rule we got:

$P(z>2.190 )= 1-P(z$

Step-by-step explanation:

For this case w eknow the following parameters:

$\mu = 2.32$ represent the mean

$\sigma =1.24$ represent the deviation

n= 32 represent the sample sze selected

We want to find the following probability:

$P(\bar X>2.8)$

We can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{2.8 -2.32}{\frac{1.24}{\sqrt{32}}}=2.190$

And using the normal standard distribution and the complement rule we got:

$P(z>2.190 )= 1-P(z$
