Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90

Complete the point-slope equation of the line through (-8,-8)(−8,−8)left parenthesis, minus, 8, comma, minus, 8, right parenthes
Ksivusya [100]

Answer:

<h2>y-9 = 17(x+7)</h2>

Step-by-step explanation:

Given the points (-8, -8) and (-7, 9), the general form of equation of the line passing through this point is expressed as y-y1 = m(x-x1) where;

m = slope or gradient and (x1, y1) is the point

m = Δy/Δx = y₂-y₁/x₂-x₁

m = 9-(-8)/-7-(-8)

m = 17/1

m = 17

The slope of the line is 17.

The point-slope equation of the line through the point (-7, 9) is expressed as

y-9 = 17(x-(-7))

y-9 = 17(x+7)

The t distribution approaches the _______________ distribution as the sample size ___________.
vredina [299]

Answer:

Normal; increases.

Step-by-step explanation:

In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.

The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.

This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.
