Answer: Option B 3!((6×5×4)-1)
Step-by-step explanation:
6! - 3!
= (1×2×3×4×5×6) - (1×2×3)
= 720 - 6
= 714
As you told you forgot to put options lemme answer it.
It will be option B
3!((6×5×4)-1)
It will be 6((6×5×4)-1)
= 6(120) -6
= 720 - 6
= 714

I want to rearrange the formula of 3+x=ax to find out what x is equal to. I already know the answer via the answer sheet but I want to know how to get that answer.
Answer:
See below.
Step-by-step explanation:
[tex]3+x=ax[/tex] (Given)
[tex]x=ax-3[/tex] (Subtracted 3 on both sides)
[tex]x-ax=-3[/tex] (Subtracted ax on both sides)
[tex]x(1-a)=-3[/tex] (Factor out x from x - ax)
[tex]x=-\frac{3}{1-a}[/tex] (Divided 1 - a on both sides)
The probability that Jess will answer any question correctly, independently of her answer to any other
question, is p (p > 0). Let the random variable Y be the number of questions that Jess answers
correctly in any set of 25.
If Pr(Y > 23) = 6 x Pr(Y = 25), show that the value of p is 5/6
Answer:
I hope my answer helps :)
Step-by-step explanation:
P(Y > 23) = P(Y = 24) + P(Y = 25)
6P(Y=25) = P(Y = 24) + P(Y = 25)
6 = P(Y = 24)/P(Y = 25)+ 1
5 = (²⁵C24×p²⁴×q¹)/(²⁵C25×p²⁵×q⁰)
Since you know that q = 1 - p,
5 = 25{[p²⁴(1 - p)]/p²⁵}
1/5 = (p²⁴ - p²⁵)/p²⁵
1/5 = p^(-1) - 1
6/5 = 1/p
p = 5/6 (shown)
In an effort to persuade customers to reduce their electricity consumption, special discounts have been offered for low consumption customers. In Florida, the EPA estimates that 70% of the residences have qualified for these discounts. If, instead, a sample of 20 residences is selected, what is the probability 12 or more will have qualified for the discounts
Answer:
please mark me brainlist
Step-by-step explanation:
p = proportion of residents qualified for discounts = 0.70
Sample size = 20
If X is the no of residences selected for discounts then x is binomial with (20,0.7)
P(X>=12) = 0.8867

Answer:
Hello,
Step-by-step explanation:
heigth of the equilateral triangle:
[tex]h=3*\dfrac{\sqrt{3}}{2}[/tex]
Area of the triangle:
[tex]A=\dfrac{6*3\sqrt{3} }{2*2} =\dfrac{9\sqrt{3} }{2} \\\\[/tex]
Area of the disk:
[tex]S=\pi*4^2=16\pi\\\\[/tex]
Probability:
[tex]p=\dfrac{9\sqrt{3} }{2*16*\pi}=0.15506125....\approx{15.5\%}[/tex]
Answer:
Step-by-step explanation:
The height of the triangle is given as 6.5, the base is given as 6, therefore, the area of the triangle is:
[tex]A=\frac{1}{2}(6)(6.5)\\A=19.5[/tex]
The area of the circle is:
[tex]A=\pi(4)^2\\A=16\pi\\A=50.26548[/tex]
Divide the area of the triangle by the area of the circle:

Find the value of x. Round to the nearest tenth
Answer:
658ft
Step-by-step explanation:
you first have to calculate the angle next to that 28°angle,if you look at the two they form a 90° so to find that angle you have to subtract 90-28=62
the x is the opposite of angle 62 and the 350 si the adjacent so you can use the tan ratio to find the answer
tan62=opposite/adjacent
tan62=y/350
y=tan62×350
=658ft

2. Find the measure of eº.
D is a vertical angle to the given 159 degrees.
E + D need to equal 180 degrees.
E = 180 - D
E = 180 - 159
E = 21 degrees
Answer: 21 degrees.
Answer: e = 21°
Step-by-step explanation:
Angle d will be 159° because alternate exterior angles are equal.
Now angle e + angle d = 180 because they form linear pair
e + d = 180
e + 159 = 180
e = 180-159
e = 21

Answer:
root 194=13.928 inches
Samira and Sonia each have a bag containing 20 sweets. In each bag, there are 5 red, 6 green and 9 yellow sweets.
(a)
(b)
Samira chooses one sweet at random from her bag.
Write down the probability that she chooses a yellow sweet.
[1] Sonia chooses two sweets at random, without replacement, from her bag.
(i) Show that the probability that she chooses two green sweets is 3 . 38
(ii) Calculate the probability that the sweets she chooses are not both the same colour.
Step-by-step explanation:
there must be some typos here. but I try to address the right issues.
there is nothing under (a). so, really nothing to answer.
(b)
there are 20 sweets in her bag. 9 if the 20 are yellow.
so, the probability is the ratio of desired possibilities vs. total possibilities.
that is, tada! 9/20
that is the probabilty for Samira to pick a yellow sweet.
[1] (i)
again, 20 sweets to start with.
6 are green.
when she picks the first one, her probability to pick a green one is 6/20 = 3/10 = 0.3
and now, under the assumption that this came true, she picks another sweet.
this time she had only 19 left, and 5 of them are green.
so, this probabilty is 5/19
now both events need to happen for the case we are discussing. there is no overlapping, no ors, ifs and buts. it is just the product of both probabilities.
3/10 × 5/19 = 15/190 = 3/38
I think that is what the description asks for.
(ii)
that probability is
first selection is red and second is not red +
first selection is green and second is not green +
first selection is yellow and second is not yellow
so,
red and not red
5/20 = 1/4 red
15/19 not red (there are still 15 sweets of other colors in the bag, but again now only 19 total).
red and not red = 1/4 × 15/19 = 15/76 = 0.1974
green and not green
6/20 = 3/10 = green
14/19 = not green
green and not green = 3/10 × 14/19 = 52/190 = 26/95 =
= 0.2737
yellow and not yellow
9/20 = yellow
11/19 = not yellow
yellow and not yellow = 9/20 × 11/19 = 99/380 = 0.2606
so, now assuming up all 3 possibilities ("or" = sum) gives us the general possibility of selecting two different colors
= 0.7316

The general formula for both secants is the entire length * the external segment.
Using an example, it is 3*(13 + 3) = 3*16
The other secant will be 4*(x + 4)
These two are equal
4(x + 4) = 3 * 16
4(x + 4) = 48 Divide by 4
x + 4 = 12 Subtract 4 from both sides
x = 8
Second Question
8(x + 8) = 6(6 + 18)
8x + 64 = 6(24)
8x + 64 = 144 Subtract 64
8x = 80 Divide by 8
x = 80 /8
x = 10

Drag and drop the numbers and symbols into the boxes to form an expression that represents this phrase:
8 more than quotient of 12 and 6
Which Order Do I Put It In?
the expression is "2 + 8." To find the quotient of 12 and 6, divide 12 by 6. The result is 2.
Step 1: Add 8 to the quotient.
Now, add 8 to the quotient found. The expression is "quotient + 8."
Step 2: Write the final expression.
The final expression that represents "8 more than quotient of 12 and 6" is "quotient + 8."

Find the slope (rate of change) of each representation. Please explain how you got it.
Answer:
m = -3/2
Step-by-step explanation:
To find the slope of the representation, use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
I'll pick (-4, 9) and (-2, 6) in this instance.
[tex]m=\frac{9-6}{-4-(-2)}\\\\m=-\frac{3}{2}[/tex]
Therefore, the slope of the representation is -3/2.
Answer:
-3/2
Step-by-step explanation:
To find the slope, we can use the formula
m = ( y2-y1)/(x2-x1)
= ( -6 -9)/(6 - -4)
= (-6-9)/(6+4)
-15/10
