A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52
Answer:
Half of year 2043
Step-by-step explanation:
The function is: f(x) = 3.5√x + 38
where f(x) represents the percentage of U.S. women in the labor force x years after 1960.
Replacing f(x) = 70 and isolating x, we get:
70 = 3.5√x + 38
3.5√x = 70 - 38
√x = 32/3.5
x = 9.14²
x = 83.5
This means, in year 1960 + 83.5 = 2043.5, that is, at half of year 2043
Answer:
The standard form is 5.61 x 10^2
Step-by-step explanation:
The standard form for a scientific notation is expressed as A * 10^n
A is any value between 1 and 10
n is an integer
Given the notation 5.61 x 10^2, this is already in scientific notation since;
A = 5.61 which is between 1 and 10 and n = 2 which is a positive integer
Answer:
A.
Step-by-step explanation:
(x − 7)^2=
=x^2 − 14x + 49
The function that has the same minimum value as fx= 3x³ is f(x) = x + 3.
<h3>What is a function?</h3>
It should be noted that a function simply means a relation or expression that involves two or more variables.
In this case, the function that has the same minimum value as the expression of 3x³ is f = x + 3.
