1 answer:
Mamont248 [21]3 years ago
4 0

Answer:

The answer is below

Step-by-step explanation:

La distancia entre dos puntos A(x₁, y₁) y B(x₂, y₂) en el plano cartesiano se da como:

AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

El paralelogramo que se muestra en el diagrama tiene vértices en P (3, 6), Q (7, 6), R (9, 2) y S (1, 2)

a) La distancia entre Q y R viene dada por:

QR=\sqrt{(9-7)^2+(2-6)^2} =\sqrt{20}=2\sqrt{5} \ units

b) La distancia entre P y R viene dada por:

QR=\sqrt{(9-3)^2+(2-6)^2} =\sqrt{52}=2\sqrt{13} \ units

Jordan enters 3.4 x6.8 into his calculator. He writes the digits 2312 from the display and forgets the decimal point. Where shou
vivado [14]

Answer:

23.12

Step-by-step explanation:

Jordan has entered 3.4 x 6.8 on his calculator.

3.4 x 6.8 = (34/10) x (68/10) = (34 x 68) / (100) = 23.12

Or an easier way would be, observing the two numbers.

In 3.4 , there is one digit after decimal point.

In 6.8 there is one digit after decimal point.

So in their product there should be two digits after the decimal point.

So the answer is <em>23.12</em>

Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 69.08 inches.

The area would be 22 if I'm not mistaken. You would divide 69.08 by 3.14 and you would get 22.

Which equation does the graph below represent?<br> y=1/3+x<br> y=1/3x<br> y=3+x<br> y=3x
barxatty [35]
Lets find 2 points, one obvious one is (0,0), another point is (12,4)

Slope = \frac{4-0}{12-0} =\frac{4}{12} = \frac{4\times 1}{4\times 3} = \frac{1}{3}

y = mx + b

m is the slope

we got m = 1/3

We can eliminate answer choices C and D.

y = 1/3x + b

we need to solve for b

Plug in the point (0,0) and solve for b

0 = 1/3(0) + b

0 = 0 + b

b = 0

The equation of the line is y = 1/3x + 0, or y = 1/3x

Your answer is B.

Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a recent year. suppose a samp
Anastaziya [24]
Given:
μ = $3.26 million, averaged salary
σ = $1.2 million, standard deviation
n = 100, sample size.

Let x = random test value
We want to determine P(x>4).

Calculate z-score.
z = (x - μ)/ (σ/√n) = (4 - 3.26)/(1.2/10) = 6.1667

From standard tables,
P(z<6.1667) = 1
The area under the distribution curve = 1.
Therefore
P(z>6.1667) = 1 - P(z<=6.1667) = 1 - 1 = 0

Answer: The probability is 0.
