Answer:
The probability that you will get 3 pictures right is 0,015625
Step-by-step explanation:
To get the probability, equally likely, of guessing the picture we use the following formula
P=# of possibilities that meet the condition / #of equally likely possibilities.
# of possibilities that meet the condition= 2
#of equally likely possibilities= 8
So every time you guees you have 2 possibilities from 8 , that give us a probability of 2/8 or 1/4
We suppose once you guess 1 card , the tester put back the card with the others.
Now, we must guess 3 pictures, that will be the multiplication of each probability.
P= 1/4 *1/4*1/4
P= 0,015625
The value of x = 24
Step-by-step explanation:
The proportion is set as ;

Applying cross product
9*16=6*x
144=6x --------simplify by dividing by 6 both sides
144/6 = 6x/6
24=x

<span>1. </span>When given a raw score, it must be converted
into a z-score (standard score). Raw scores cannot be placed on a normal
distribution curve because they do not have the same means and standard
deviations, but when it is converted into a z-score, the number of standard
deviations above or below the population mean can be measured. The z-scores on
the center are average, the scores on the left are lower than average and the
scores on the right are higher than average.
<span>2. </span>A z-score is a standard score which can be
placed on a normal distribution curve. A z-score indicates the distance of the
standard deviations from the mean (center of the curve).
We need to find the distance between (7, 5) and (10, 11) and double it, since they run it twice. We can do this as follows: 2√(11-5)² + (10-7)² = 2√36 + 9 = 2√45 = 6√5.

F(x) is continuous for all x.
Pick a point and show that f(x) is either negative or positive. Pick another point and show that f(x) is negative, if positive, or positive, if negative.
At x = 30, f(30) - 1000 = 900 + 10sin(30) - 1000 ≤ 0
Now, show at another point f(x) - 1000 is positive, and hence, there would be root between 30 and such point.
Let's pick 40.
At x = 40, f(40) - 1000 = 1600 + 10sin(40) - 1000 ≥ 0
Since f(x) - 1000 is continuous, there lies a root between 30 and 40, and hence, 30 ≤ c ≤ 40
