X ·( x + 1 ) = 600
x² + x = 600
x² + x - 600 = 0
x = ( - 1 - 49 ) / 2 = - 50 : 2 = - 25
x = - 25, x + 1 = - 24
( - 25 ) · ( - 24 ) = 600
Answer:
C ) - 25
There should be 8 red cars in each box and 6 blue cars in each box
Answer:
Pythagorean Theorem: C²= a²+b²
a²+b²=c²
C is the longest line of a right angled triangle and a and b are the other two. If you have "a" and "c", but need to find b. You need to sqaure a and then subtract that from c². Then you have b
An Exponent is any example of ². When a small number is above another number. You multiple the "original" number x amount of time. Ex. 3³ 3*3*3
Bedmas is another way of saying "order of operation". Its the order that you calculate functions. It is calculated in this order: Brackets, Exponents, Division/Multiplication, Addition/Subtraction.
I attached an example of Mean, Median, Mode, and Range.
Area: Area is the total space that a 2D object covers. And to calculate it we have to multiply the length of two sides that share a corner. For example, if we have a rectangle that the length of one side is equal to 3cm and the second side is equal to 5cm. Then we multiply them together to get the area. 3*5=15
Perimeter: The perimeter is the "outline" of a 2D shape. To calculate the perimeter we have to add all the sides together.
Answer:
1/2b x h
1/2(5 2/3) x 3
Step-by-step explanation:
Answer:
0.1384
Step-by-step explanation:
Using binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Given n = 25, r = 4, p = 0.10, and q = 0.90:
P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴
P = 12650 (0.10)⁴ (0.90)²¹
P = 0.1384
