Whats the exspression equivalent to (-2x + 8.1y)

Simora [160]

Answer:

b. 7x + 2.8y

Step-by-step explanation:

distribute the negative sign:

= -2x + 8.1 + -1(-9x + 5.3y)

= -2x + 8.1 + -1(-9x) + -1(5.3y)

= -2x + 8.1 +9x + -5.3y

combine like terms:

= (-2x + 9x) + (8.1 + -5.3y)

= 7x + 2.8y

Which ordered pair is the best estimate for the solution of the system of equations? y=32x+6 y=14x−2

Marysya12 [62]

since y = both rewrite as

32x+6 = 14x-2 and solve for x

32x +6 = 14x-2

add 2 to both sides:

32x +8 = 14x

subtract 32x from both sides:

8 = -18x

divide both sides by -18

x = 8/-18 which reduces to -4/9

now use that for x and solve for Y

32(-4/9) +6 = -74/9

ordered pair:

(-4/9, -74/9)

Suppose that 0.10 of population is colourblind if 25of sample drown from this population find probability that at least 7 have c

Leokris [45]

Answer:

$P(X \geq 8)=22*10^{-4}$

Step-by-step explanation:

From The Question we are told that

Prob that population is colourblind $P(C)=0.10$

Sample size $N=25$

Generally the equation for Number of color blinds is mathematically given by

$P(X \geq 8)=\sum^{25}_{x=8}(25..x)(0.10)^x(0.90)^25-x$

$P(X \geq 8)=22*10^{-4}$

Makayla has $8 to buy tickets at the school fair. Each ticket costs @1.5. Which inequality best represents how many tickets she

cricket20 [7]

Answer:

$n\le 5$

Step-by-step explanation:

Let n be the number of tickets Makaya has to buy.

If the cost of one ticket is $1.5, then the cost of n tickets is $1.5n.

Makayla has $8 to buy tickets at the school fair, thus

$1.5n\le 8\\ \\n\le \dfrac{8}{1.5}\\ \\n\le \dfrac{80}{15}\\ \\n\le \dfrac{16}{3}\\ \\n\le 5\dfrac{2}{3}$

The maximum number of tickets Makaya can buy is 5, so

$n\le 5$
