Answer:

slope = 4

y intercept = -3

Step-by-step explanation:

The equation is put in slope intercept form

Slope intercept form: y = mx + b

where m = slope and b = y intercept

looking at slope intercept form

4 is located where m should be , meaning that the slope is equal to 4 and

-3 is located where b should be , meaning that the y intercept is -3

Therefore the answers are the first and last option choices.

Pepe compró una caja de chocolates en $5.950, incluido el 19% de IVA. ¿Cuál es el precio de la caja de chocolates sin el IVA?

Answers

Answer:

$4819.5

Step-by-step explanation:

Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?

The price of chocolates = $5,950

VAT = 19%

We need to find the price of the box of chocolates without VAT.

VAT is applied on the Cost price of the object.

Price = $5,950 - 19% of $5,950

[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]

So, the price of the box without VAT is equal to $4819.5.

numbers that lies exactly half way between-2,4 and 1, 7​

Answers

Answer:

(- 0.5, 5.5 )

Step-by-step explanation:

Using the midpoint formula

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (1, 7) , then

midpoint = ( [tex]\frac{-2+1}{2}[/tex], [tex]\frac{4+7}{2}[/tex] ) = ( [tex]\frac{-1}{2}[/tex], [tex]\frac{11}{2}[/tex] ) = ( - 0.5, 5.5 )

A box contain 10 green pins 3 are blue and 7 are green. Two pins are randomly taken out of the box without replacement work out the probability that both pins are the same color

Answers

Answer:

[tex]P(Z)=\frac{8}{15}[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=10[/tex]

Green pins [tex]x=7[/tex]

Blue pins [tex]y=3[/tex]

 

Generally the probability of getting two green is mathematically given by

[tex]P(2X)=\frac{7}{10}*\frac{6}{9}[/tex]

[tex]P(2X)=\frac{7}{15}[/tex]

Generally the probability of getting two blue is mathematically given by

[tex]P(2Y)=\frac{3}{10}*\frac{2}{9}[/tex]

[tex]P(2Y)=\frac{1}{15}[/tex]

Therefore the probability that both pins are the same color P(Z)

[tex]P(Z)=P(2Y)+P(2X)\\P(Z)=\frac{7}{15}+\frac{1}{15}[/tex]

[tex]P(Z)=\frac{8}{15}[/tex]

Though I swam very well, I could not deliver myself from the waves so as to draw breath, till that wave having driven me, or rather carried me, a vast way on towards the shore, and having spent itself, went back, and left me upon the land almost dry, but half dead with the water I took in. I had so much presence of mind, as well as breath left, that seeing myself nearer the mainland than I expected, I got upon my feet, and endeavored to make on towards the land as fast as I could before another wave should return and take me up again.However, I soon found it was impossible to avoid it; for I saw the sea come after me as high as a great hill, and as furious as an enemy, which I had no means or strength to contend with: my business was to hold my breath, and raise myself upon the water if I could.By swimming, I could preserve my breathing, and pilot myself towards the shore, if possible. My greatest concern now being that the sea, as it would carry me a great way towards the shore when it came on, might not carry me back again with it when it gave back towards the sea. The wave that came upon me again buried me at once twenty or thirty feet deep in its own body.I could feel myself carried with a mighty force and swiftness towards the shorea very great way, but I held my breath, and assisted myself to swim still forward with all my might.I was ready to burst with holding my breath, when, as I felt myself rising up, so, to my immediate relief, I found my head and hands shoot out above the surface of the water. Though it was not two seconds of time that I could keep myself so, yet it relieved me greatly, gave me breath, and new courage.I was covered again with water a good while, but not so long but I held it out; and finding the water had spent itself, and began to return, I struck forward against the return of the waves, and felt ground again with my feet.I stood still a few moments to recover breath, and till the waters went from me, and then took to my heels and ran with what strength I had further towards the shore. But neither would this deliver me from the fury of the sea, which came pouring in after me again; and twice more I was lifted up by the waves and carried forward as before, the shore being very flat. The last time of these two had well-nigh been fatal to me, for the sea having hurried me along as before, landed me, or rather dashed me, against a piece of rock, and that with such force, that it left me senseless, and indeed helpless, as to my own deliverance. The blow taking my side and breast, beat the breath as it were quite out of my body; and had it returned again immediately, I must have been strangled in the water; but I recovered a little before the return of the waves.Seeing I should be covered again with the water, I resolved to hold fast by a piece of the rock, and so to hold my breath, if possible, till the wave went back.Now, as the waves were not so high as at first, being nearer land, I held my hold till the wave abated, and then fetched another run, which brought me so near the shore that the next wave, though it went over me, did not so swallow me up as to carry me away. The next run I took, I got to the mainland, where, to my great comfort, I clambered up the cliffs of the shore and sat me down upon the grass, free from danger and quite out of the reach of the water.
