Answer:

b= square root of c^2-a^2

Step-by-step explanation:

When givin measurements of a and c you have to subtract them both but with square rooting them and squaring them. Hope this helped

We need to find α=Q3 such that P(z≤α)=0.75
From the standard table, we get
P(Z≤0.675)=0.75
thus
α=0.675
⇒[H-63.6]/2.5=0.675
solving for H we get
H-63.6=1.6875
hence
H=65.2875
The 3rd quartile is 65.2875

Step-by-step explanation:

The circumference of a circle's formula is pi*d (d being diameter).

If it only shows you the radius, then the formula would be 2*pi*r (r being radius), this is the same as pi*d.

2*r = d

Question 2

The circle has a diameter of 100m. Find circumference

pi*d

pi*100

On a coordinate plane, triangle L M N is shown. Point L is at (2, 4), point M is at (negative 2, 1), and point N is at (negative

Crank

Perimeter is 8 + √(10) units.

<u>Step-by-step explanation:</u>

First we have to find the distance between the all the 3 points and then using the distances, we can find the sum of it, so that we will get the perimeter of the triangle.

The points are L(2,4) , M(-2,1) and N(-1,4)

Distance between the points can be found as,

√((x₂-x₁)² + (y₂-y₁)²)

Plugin the values in the given point, we will get LM as,

LM = √((-2-2)² + (1-4)²)

= √((-4)² + (-3)²)

= √(16 + 9) = √(25) = 5 units.

MN = √((-1-(-2))² + (4-1)²)

= √((-1+2))² + (4-1)²)

= √((1))² + (3)²)

= √(1 + 9) = √(10)

NL = √((2-(-1))² + (4-4)²)

= √((3)² + 0²) = √(9) = 3 units

Perimeter = LM + MN + NL = 5+ √(10) + 3 = 8 + √(10) units.
