Answer:
The probability of picking a black card at random, from a deck with 3 black cards and 7 red ones is 0.3.
Step-by-step explanation:
We will assume that we have 3 black cards and 7 black cards, for a total of 10 cards. Since we are taking one card at random, we can assume that each card is equally likely to be drawn. We have the following event A: The drawn card is a black. We will find the probability of A as counting the number of outcomes that make A to occur and divide it by the total number of possibilities. We are drawing one card, so we have 10 possibilities to be picked. Out of those 10, only 3 cards are black, hence we have 3 possibilites of picking a black card.
Then,
P(A) = 3/10 = 0.3.
Answer:
$210
Step-by-step explanation:
Formula:
P = A (1 + r% x t)
P: Answer
A: Original value
R%: Percentage increase
T: Time
P = 200 (1 + 5% x 1)
P = $210
Answer:
3
Step-by-step explanation:
The equation being used to express the answer is called slope-intercept form.
y = m x + b
m is the slope, b is the y-intercept (where x = 0)
The formula to find slope (m) using two points is called point slope form.
m = (y1 - y2)/(x1 - x2)
Pick two coordinates and plug them in.
m = (1 - 4)/(0 - 1)
m = (-3/-1)
m = 3
Answer: the statement made by Tim Cook is TRUE
Step-by-step explanation:
Given that;
in 2007 cost of 1st gen iphone = $499 (base year price)
cost of iphone today = $999 (current year price)
Using the Consumer Price Index
the Consumer Price Index = (cost pf product in current years/cost of product base year) × 100
we substitute
CPI = (999/499) × 100
CPI = 200.2004
so the CPI is 100.2004% higher in the current year than in the base year
Checking the inflation rate
IR = (( CPI this year- CPI last year)/CPI last year) × 100
CPI last year (base year) = 100
CPI current year is = 100.2004
so
IR = (( 100.2004 - 100)/100) × 100
IR = 0.002004 × 100
IR = 0.2004%
THEREFORE the statement made by Tim Cook is TRUE
Answer:
C
Step-by-step explanation:
Let's just look at the point G(3) = 3
this point only occurs through one equation which is
g(x) = (1/3)x^2
