Answer:

Step-by-step explanation:

→ Prime factorise each number

12 = 2² × 3 ⇒ 2 × 2 × 3

18 = 2 × 3² ⇒ 2 × 3 × 3

24 = 2³ × 3 ⇒ 2 × 2 × 2 × 3

→ Find which number there are in each one

2 and 3

→ Multiply them together

2 × 3 = 6

Slove for P. 5/7=p+4/7

Sever21 [200]

p= 1/7
Alright, so first, you need to flip the equation.It will turn into p+4/7=5/7
Next, you want to get the variable by itself so you need to subtract 4/7 from both sides. 5/7-4/7=1/7
p=1/7

5) If Oskar bisects the diameter of a circle, what is he trying to construct?

pav-90 [236]

Answer:

Center = (5,-3) and radius = 7

Step-by-step explanation:

(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.

(6) The given equation is :

$(x-5)^2+(y+3)^2=49$

The general equation of circle is given by :

$(x-a)^2+(y-b)^2=r^2$ ...(1)

Where

(a,b) are the coordinates of the centre and r is the radius.

The given equation can be written as :

$(x-5)^2+(y+3)^2=7^2$ ..(2)

Comparing equation (1) and (2) we get :

a = 5, b = -3 and r = 7

So,

Center = (5,-3) and radius = 7

Hence, this is the required solution.

On a standardized exam, the scores are normally distributed with a mean of 145 and a standard deviation of 25. Find the z-score

Kryger [21]

Answer:

z = 2.6

Step-by-step explanation:

Use the formula for z-score

$z=\frac{x-\mu}{\sigma}\\ \\z=\frac{210-145}{25}\\ \\z=\frac{65}{25}\\ \\z=2.6$

This tells us that this person's score of 210 places them 2.6 standard deviations above the mean
