<u>Answer:</u>

Probability that none of the meals will exceed the cost covered by your company=0.2637

Probability that one of the meals will exceed the cost covered by your company=0.4945

Probability that two of the meals will exceed the cost covered by your company=0.2197

Probability that three of the meals will exceed the cost covered by your company=0.02197

<u>Step-by-step explanation:</u>

15 restaurants located in Boston is relevant for this question.

One third of 15 means, 5 restaurants will always exceed 50$

So,

We can use combinations, as we don’t know the exact 5 restaurants out of the 15

None of the meals will exceed,

10 restaurants will not exceed the rate and we will surely have to go to 3 restaurants so

10C3/15C3

= (10*9*8/1*2*3)/ (15*14*13/1*2*3)

=120/455

=0.2637

One of the meals will exceed,

We have to visit 3 restaurants but one will exceed.

So,

(10C2*5C1)/15C3

= ((10*9/1*2) *5)/ (15*14*13/1*2*3)

=45*5/455

=225/455

=0.4945

Two of the meals will exceed,

We visit 3 restaurants but two will exceed.

So,

(10C1*5C2)/15C3

= ((10*5*4/1*2))/ (15*14*13/1*2*3)

=100/455

=0.2197

All 3 meals will exceed.

So,

5C3/15C3

= (5*4*3/1*2*3)/ (15*14*13/1*2*3)

=10/455

=0.02197

Fatima purchased a new mattress when it was on sale. The sale price was 20% less than the regular price. If the sale price was $
Drupady [299]

well, the regular price is really "x", which oddly enough is 100%, but we also know that $358 is really the discounted price by 20%, namely 100% - 20% = 80%, so we know that 358 is really just 80% of "x", so

\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 358& 80 \end{array} \implies \cfrac{x}{358}~~=~~\cfrac{100}{80} \\\\\\ \cfrac{x}{358}=\cfrac{5}{4}\implies 4x=1790\implies x=\cfrac{1790}{4}\implies x\approx 448

??please help me solve​
lilavasa [31]

Answer:

y = -4x - 6

Step-by-step explanation:

slope-intercept form: y = mx + b

Given: Slope: -4

Point: (-2, 2)

To write an equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). Since we were given the value of the slope, all we have to do now is find b. To do this, input the given values of m and the point into the equation and solve for b:

y = mx + b

2 = -4(-2) + b

2 = 8 + b

-6 = b

The y-intercept is -6.

Now that we know the slope and the y-intercept, we can write the equation:

y = -4x - 6
