Answer:

1, 4, 6

Step-by-step explanation:

#1 - think of it as a fraction. if you have two triangle and four squares when simplifying you get ½. which is what #1 means. for #4 it is the same thing except flipped around. instead of it being triangles to squares it's squares to triangles. for #6 again it's a fraction. simplify the fraction getting you ½ again. if you have 6/2 and reduce it you have 3/1 showing that for every 3 smiley faces there is 1 triangle as stated in the option. hope this helps you with the answer and understanding.

Hello, here's the question :D
antoniya [11.8K]

Answer:

(examples) n = 2

n = 3

n = 4

Step-by-step explanation:

to demonstrate, all you do is select a number to represent 'n' and plug it in.

so for example, n = 2:

2(2) + 3(2) = 5(2)

4 + 6 = 10, which is true.

Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5). Show your work.
luda_lava [24]

Answer: The coordinates of the circumcenter is (\frac{9}{2}, -1).

Explanation:

The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).

Distance formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

DE=\sqrt{(8-1)^2+(3-3)^2}=7

FE=\sqrt{(1-8)^2+(-5-3)^2}=\sqrt{7^2+8^2}

DF=\sqrt{(1-1)^2+(-5-3)^2}=8

Since triangle follows pythagoras theorem,

(DF)^2+(DE)^2=(FE)^2

Therefore the given triangle is a right angle triangle.

Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.

The circumcenter of a right angle triangle is the midpoint of the hypotenuse.

The hypotenuse is EF. The midpoint of EF is,

Midpoint =(\frac{8+1}{2}, \frac{3-5}{2} )=(\frac{9}{2}, -1)

Therefore, the coordinates of the circumcenter is (\frac{9}{2}, -1).

Suppose that at Northside High, the number of hours per week that seniors spend on homework is approximately Normally distribute
Aliun [14]

Answer:

The mean of the sampling distribution of means for the 36 students is of 18.6 homework hours per week.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

For the population, the mean is 18.6. So, by the Central Limit Theorem, the mean of the sampling distribution is also 18.6.
