4 0

Answer:

3, 5, 7

Step-by-step explanation:

We can assign the first number as x. Since all the numbers are odd the next number will be x+2, and the last will be x+4.

3*(x+4) = 7(x)

3x+12 = 7x

12 = 4x

x = 3

x+2 = 5

x+4 = 7

The area of a rectangle is 150 in². The ratio of the length to the width is 3:2. Find the length and the width.

kap26 [50]

Answer:

Width = 10 in

Length = 15 in

Step-by-step explanation:

L / W = 3 / 2

L = 3/2 W

L * W = 3/2 W *W = 3/2 W² = 150

w² = 150 * 2/3 = 100

W = 10 in

L = 15 in

HELP PLSSS IT'S A FINALLL!!!!!!!!!!! WILL GIVE BRAINLEST AND 50 POINTS!!!! PLEASE PLEASE PLEASE HELP!!!!

Lelu [443]

Answer:

Step-by-step explanation:

1). By applying Pythagoras theorem in the triangle formed by two sides and the diagonal,

Length of the diagonal = $\sqrt{(\text{side})^2+(\text{side})^2}$

= $(\text{side})\sqrt{2}$

= 25√2

AC ≈ 35.56 units

2). Since, diagonal of a square is the angle bisector of interior angles of the square,

m∠CAB = 45°

By applying sine rule in ΔABC,

sin(45°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$\frac{1}{\sqrt{2}}=\frac{AB}{AC}$

$\frac{1}{\sqrt{2}}=\frac{25}{AC}$

AC = 25√2

AC ≈ 35.56 units

The average number of customers arriving at a gas station is 33 per hour during lunch hours. Use equation to denote the number o

Paha777 [63]

Answer:

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is 2.75.

Step-by-step explanation:

Let X = number of customers arriving at a gas station in an hour.

The average customers arriving at a gas station in an hour is, λ = 33.

The random variable X follows a Poisson distribution with parameter λ.

The probability mass function of a Poisson distribution is:

$P(X=x)=\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,3...$

In 60 minutes the number of arrivals is, 33.

In 1 minute the number of arrival will be, $\frac{33}{60}$ .

Then in 5 minutes the number of arrivals will be, $\frac{33}{60}\times5$ .

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is

$\frac{33}{60}\times5=2.75$

Thus, the number of arrivals in 5 minutes is 2.75.
