What is the distance between point A (-2 , -1) and point B (3, 2)?

Mathematics
1 answer:
lana [24]2 years ago
4 0

Answer:

Distance = √34

Step-by-step explanation:

Using the formula for distance

d = √(x_2 - x_1)^2 + ( y_2 - y_1)^2

Using what we are provided with

Two points

( -2, -1)(3, 2)

x_1 = -2

y_1 = -1

x_2 = 3

y_2 = 2

Inserting the values

d = √ ( 3 -(-2)^2 + (2-(-1)^2

= √ (3+2)^2 + (2+1)^2

= √ 5^2 + 3^2

= √25 + 9

= √34

= 5.83

Ill give a brainliest <br> i need help its due today
aliya0001 [1]

Answer:

w=15

Step-by-step explanation:

-24=-3w+21

We move all terms to the left:

-24-(-3w+21)=0

We get rid of parentheses

3w-21-24=0

We add all the numbers together, and all the variables

3w-45=0

We move all terms containing w to the left, all other terms to the right

3w=45

w=45/3

w=15

Guys look at the pic of the park and read the question I need this ASAP WITH ALL STEPS the choices are
Alik [6]

Answer:

A. 821.5 Square Yards

Step-by-step explanation:

30 x 30= 900

900 is the area for the whole park

To find the pool area you need to do pi times Radius squared

so 3.14 x 5 x 5

That equals 78.5 for the pool area.

So to find the grass area you need to subtract the pool area from the park

900 - 78.5 = 821.5 square yards!

The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mea
zheka24 [161]

Answer:

$301 - $397

Step-by-step explanation:

Using the Empirical rule

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 349 , standard deviation = 24.

Confidence interval = 95%

Using 2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

μ – 2σ

= 349 - 2(24)

= 349 - 48

= 301

μ + 2σ

349 + 2(24)

= 349 + 48

= 397

Therefore, according to the standard deviation rule, approximately 95% of the students spent between $301 and $397 on textbooks in a semester.
