Answer: Statement 2 (P(odd number) = 1/2) is true

Step-by-step explanation:

Statement 1: there are 4 even numbers (2, 4, 6, 8) so therefore a 1/2 chance, not a 1/8. [FALSE]

Statement 2: there are 4 odd numbers (1, 3, 5, 7) so therefore a 1/2 chance, so this is true. [TRUE]

Statement 3: 8 is the biggest number, so there are 7, not 1, numbers less than it. [FALSE]

Statement 4: there is no 9 on an 8 sided cube. [FALSE]

Y=-3/2(x+2)(x-4) vertex form?

slega [8]

Answer:

Step-by-step explanation:

y=-3/2(x+2)(x-4)

=-3/2(x²-4x+2x-8)

=-3/2(x²-2x-8)

=-3/2(x²-2x)-3/2×-8

=-3/2 (x²-2x+1-1)+12

=-3/2(x-1)²+3/2+12

=-3/2(x-1)²+27/2

Como Determinar a equação da reta que passa pelos pontos A(-1, -2) e B(5,2)

Komok [63]

Answer:

A equação da reta é dada por: $y = \frac{2}{3}x - \frac{4}{3}$

Step-by-step explanation:

Equação de uma reta:

A equação de uma reta tem o seguinte formato:

$y = ax + b$

Em que a é o coeficiente angular e b é o coeficiente linear.

Coeficiente angular:

Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.

A(-1, -2) e B(5,2)

Mudança em y: 2 - (-2) = 2 + 2 = 4

Mudança em x: 5 - (-1) = 5 + 1 = 6

Coeficiente angular: $m = \frac{4}{6} = \frac{2}{3}$

Então:

$y = \frac{2}{3}x + b$

Coeficiente linear:

Substituindo um ponto na equação, encontra-se o coeficiente linear.

B(5,2)

Quando $x = 5, y = 2$ . Então:

$y = \frac{2}{3}x + b$

$2 = \frac{2}{3}5 + b$

$b = 2 - \frac{10}{3} = \frac{6}{3} - \frac{10}{3} = -\frac{4}{3}$

Então:

$y = \frac{2}{3}x - \frac{4}{3}$

The davis family traveled 35 miles in 1/2 hour if it is currently 2:00pm any the family destination is 245 miles away at what ti

xxMikexx [17]

The distance traveled by Davis family = 35 miles

Time taken to cover the distance = $\frac{1}{2}$ hour

Speed = Distance $\div$ Time

Speed = $35 \div \frac{1}{2}$

Speed = $35 \times 2$

So, speed = 70 miles/hour.

At 2:00 pm, the family destination was 245 miles away.

So, the number of hours, when the family was 245 miles away = $245 \div 70$

= 3.5 hours

So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.
