Answer:

Domain: { -3,1,6}

Step-by-step explanation:

The domain is the input values

Domain: { 6,1,-3,-3}

We usually put them in numerical order and we do not list the same value twice

Domain: { -3,1,6}

If they manage to sell $t$ tickets, they will earn $15\cdot t$ dollars. We want this number to be at least 1000, so the inequality would be

$15t>1000$

In order to solve this for t, you only need to divide both sides by 15:

$15t>1000\iff t>\dfrac{1000}{15} = 66.\overbar{6}$

So, they need to sell at least 67 tickets to have an income of

$15\cdot 67 = 1005$ dollars

Using the given points and line, determine the slope of the line. (-3,0) and (2,7)

o-na [289]

Answer:

slope = $\frac{7}{5}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (2, 7)

m = $\frac{7-0}{2+3}$ = $\frac{7}{5}$

Answer:

a. 0.6899

b. 0.1642

Step-by-step explanation:

a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.94\times0.94\times0.94\times0.94\times0.94\times0.94\\\\=0.6899$

Hence, the probability of correctly identifying the 6 matches is 0.6899

b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.74\times0.74\times0.74\times0.74\times0.74\times0.74\\\\=0.1642$

#Hence, the probability of correctly identifying the 6 matches is 0.1642

*I have used the sample size of 6(due to conflicting info/question size).

Question:

A rectangle has a height of 2x^4 and a width of x^2+8x+15. Calculate its area.

Answer:

$Area = 2x^6 + 16x^5 + 30x^4$

Step-by-step explanation:

Given

$Height = 2x^4$

$Width = x^2 + 8x + 15$

Required

Determine the area of the rectangle

This is calculated as:

$Area = Width * Height$

$Area = (x^2 + 8x + 15) * 2x^4$

$Area = 2x^6 + 16x^5 + 30x^4$
