There are different kinds of curves. All density curves must satisfy the conditions that;
The curve does not go below horizontal axisThe total area under the curve is = 1. What conditions must a density curve adhere to?Note that a probability density curve must satisfy two key requirements: that is;
F(x) have to be nonnegative for all value of the random variable.The integral that is over each values of the random variable have to be equal to one.A density curve is regarded as a curve that is said to be always on or found above the horizontal axis, that is, it is always negative and its area is equal to 1 under it.

Answers
Answer:
19.7 inches
Step-by-step explanation:
circumference of a circle = 2πr
62 = 2*22/7 *r
r = 62 * 7 / 44 = 9.86
diameter = 2* r
= 2* 9.86

2. One bag of fertilizer will cover 400 square feet. Find how many bags should be purchased to cover a garden that is
35 feet by 75 feet.
Answers
35*75 is
2625
2625/400 is
6.5625
Since you cannot have a decimal amount of a bag, you should purchase
(rounding)
7 bags of fertilizer
Answer:
7 bags
Step-by-step explanation:
First thing you need to do is figure out the area of the garden. Area=length×width, so just put in your numbers, 35×75=2625 square feet. One bag covers 400 feet, so you divide the area by 400, 2625÷400=6.5625. You can't buys 6.5625 bags of fertilizer, so you have to go up to the next whole number which is 7.

probability (a) = 25%
probability (b) = 60%
determine probability (a and b)
Answers
Answer:
85%
Step-by-step explanation:
P(a) = 25%=1/4
P(b) = 60%=3/5
P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%
Answer:
The probability of A and B is 85%
Step-by-step explanation:
It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.
how does the graph of g(x) = (x - 3)^3 - 2 differ from the group of f(x) = x^3?
A. g is shifted 3 units right and 2 units up.
B. g is shifted 3 units right and 2 units down.
C. g is reflected across the y-axis.
D. g is rotated 90* clockwise.
Answers
Answer:
B
Step-by-step explanation:
f(x) = x³
g(x) = (x - 3)³ - 2
The inside of the parenthesis represents a horizontal shift
If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.
The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.
the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units
we can conclude that g is shifted 3 units right and 2 units down
the answer is B

Answer:
x = ln (y)
Step-by-step explanation:
There's two main ways to solve this. When there is no logarithm in the equation you can either take the log of both sides OR change an exponential equation to logarithmic form.
See image.
note: log_2 (2) = 1
log_3 (3) = 1
log_4 (4) = 1
log_5 (5) = 1
if the base and the article are the same then it equals 1
ln e = 1
because ln e means the same thing as log_e
log_e (e) = 1
e is just a number!
If you are changing exponential form to logarithmic form, the base is the same in both forms. The base is the base. The base in exponential form is the base in logarithmic form. The base is the base. The exponent and article basically switch places to change forms.

An angle measures 52.8 degrees more than the measure of its supplementary angle. what is the measure of each angle?
Answers
Answer: 116.4 and 63.6 degrees
Step-by-step explanation:
Let the angle be x, so supplement is 180-x.
This means x - 52.8 = 180 - x
2x = 232.8
x = 116.4
So the angle measures are 116.4 and 63.6 degrees
Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Answers
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
• Principal (P) = Rs.57,000
• Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
• Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680

PLEASE HELP! I cant figure these out!
Answers
"I can't figure this out" means you lack the ability or faith in yourself to figure "this" out. You can't do it.
"I don't figure this out" sounds weird. It's possible to paraphrase it in the past or future tenses, but in the present it's usually said in present continuous, i.e "I'm not figuring this out" (as "to figure out", per se, is a process of sorts) and literally means you do not occupy yourself with figuring "this" out at this moment or generally.
