Answer:

-4/5

Step-by-step explanation:

Two points that I see are not decimals are (-3,1) and (2,-3)

y1-y2/x1-x2= slope

-3-1/2-(-3)= -4/5

ANTONII [103]

Answer:

Hence the degrees of freedom are associated with the critical value is 25.

Step-by-step explanation:

Using two independent samples, two population means are

compared to determine if a difference exists, the population standard deviation is equal.

sample size 1 = $n_{1}$ = 15 and sample size 2 = $n_{2}$ = 12

since, population standard deviations are equal, required degrees of freedom

$= n_{1} + n_{2} - 2 \\= 15 + 12 - 2\\ = 25$

Suppose you have $100 in a savings account earning 2 percent interest a year. After five years, would you have more than $102, e

pentagon [3]

You would have more than $102.

Earning 2% a year in interest would get you $2 in interest the very first year:

100(0.02) = 2

Adding this to the amount in the account, you would have 100+2 = 102 after the first year.

∀x∃y ∃z ¬T(x, y, z)

b) ∀x¬[∃y (P(x, y) ∨ Q(x, y))]

∀x∀y ¬ [P(x, y) ∨ Q(x, y)]

If $6000 was expected in sales and only $5100 was attained, what reduced fraction represents sales attained?

ira [324]

The reduced fraction that represents the sales attained is 17/20

<h3>How to determine the fraction?</h3>

The given parameters are:

Expected = $6000

Attained = $5100

The fraction is represented as:

Fraction = Attained/Expected

So, we have:

Fraction = 5100/6000

Divide by 300

Fraction = 17/20

Hence, the reduced fraction is 17/20
