Area of the triangle = (1/2)*base* height = (1/2)*3*6 = 9 sm²
We have 4 triangles like this one ,
so area of 4 triangles = 9*4 = 36 cm².
Area of the square = 3*3 = 9 cm²
Surface area here means area all triangles + area of the square =36 +9 =
= 45 cm ²
Answer is 45 cm².
The answer is A
in a y-int your x coordinate is always going to be 0
Answer:
$60
Step-by-step explanation:
multiply $300 by 20%
20% = = 0.2, hence
20% of $300 = $300 × 0.2 = $60
U multiply it as u would multiply a two digit and a one digit number step by step only then u have to multiply the second number like u did to the other number and u add a zero then add them and u get ur answer
Answer:
So we want to find this probability:
And using the normal standard distirbution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the age of men married of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
The sample size is n =66. We can use the z score to solve this problem:
If we find the z score for 25 we got:
So we want to find this probability:
And using the normal standard distirbution or excel we got:
