Answer:
a) 24
b) 12
Step-by-step explanation:
a) For the 4 letters of the word ROCK
Selecting any first letter, we have 4 options
for the second, we have 3 options
for the third we have 2 options
for the fourth, we have only one option
So the number of ways will be ;
4 * 3 * 2 * 1 = 24 ways
b) 2 out of 4
For the first letter, we have 4 options, for the second, we have 3 options
so the number of options is 4 * 3 = 12 options

Tom's property has a shape of a parallelogram with the dimensions of l= x +75 and w= x + 45. If the perimeter is 300 feet, what is the value of x
Answer:
15 feets
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets

16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
Answer:
70.06
Mean score = 70
Step-by-step explanation:
16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
For a normal distribution :
Zscore = (x - mean) / standard deviation
x = score
P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)
Therefore ;
0.994 = (80 - mean) / 10
0.994 * 10 = 80 - mean
9.94 = 80 - mean
Mean = 80 - 9.94
Mean = 70.06
Hence, the mean score = 70.06 = 70

What is the inverse of the function f(x) = x +3? 1 O h(x) = = x + 3 3 5x+3 = Oh(x) = rx - 3 3 Oh(x) = x-3 O h(x) = x + 3
Answer:
C
Step-by-step explanation:
the inverse of x+3 is x-3
The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x)= x + 3
Now, We can find the inverse function as;
⇒ f (x) = x + 3
⇒ y = x + 3
Solve for x;
⇒ x = y - 3
Substitute y = x and x = h (x);
⇒ h (x) = x - 3
Thus, The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3

A parallelogram with a height of 2x+3 has an area listed below. What is the length of the base of the parallelogram? 2x^2+13x+15
Answer:
x+5
Step-by-step explanation:
I thought what 2 numbers if multiplied made 15
also 2x+3 already has a 3
so I'm guessing 3 and 5
then I put them next to each other
(2x+3) ( +5)
I put a x in the second parenthesis as a guess because the area had a 2x^2 in it . that could only happen with 2x * x
so (2x+3) (x+5)

Step-by-step explanation:
Step-by-step explanation:
From the given figure , we can see that there are two angles whose measures are x and 2x - 30°. If we notice they are the angles on the same segment . ( Draw a line through the end points of the two lines , and they will be on the same chord) . And we know that angles of the same segment are equal . Therefore ,

Find the value of X.
Answer:-
x=110 degree
Step-by-step explanation:
It's quadrilateral so it's total sum degree is 360
then 40+82+128+x=360
360-(128+82+40)=X
x=360-250
x=110 degree
