Answer:
growth rate is the number of times the base repeats
Step-by-step explanation:
We have that the general form of the exponential function is of the type:
f (x) = a ^ x
where "a" is the base and "x" is the exponent.
Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.
The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.
Exponential functionThe standard exponential function is expressed as y = ab^x
where:
a is the y-interceptb is the ratex is the time taken.The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.

Miki tosses a coin 50 times, and the coin shows tails 28 times.
What is the experimental probability of Miki getting tails?
Answer:
28/50, or 56 percent.
Step-by-step explanation:
Divide the number of events (in this case it's tails) by the number of possible outcomes. This means to divide 28 by 50. Your answer will be 0.56. As a percent, this is 56 percent, which is the probability of the coin landing on tails.

Part (i)
Compute the slope of the line through the two points (0,0) and (4,8)
m = (y2 - y1)/(x2 - x1)
m = (8-0)/(4-0)
m = 8/4
m = 2
The slope of this line is 2, so,
velocity = 2 m/s==============================================
Part (ii)
The two points we're working with are (4,8) and (6,8). The slope is...
m = (y2 - y1)/(x2 - x1)
m = (8-8)/(6-4)
m = 0/2
m = 0
Horizontal lines always have a slope of 0 to indicate no change in height.
The velocity is 0 m/s.==============================================
Part (iii)
Same idea as the previous parts. The endpoints are (6,8) and (9,14)
m = (y2 - y1)/(x2 - x1)
m = (14-8)/(9-6)
m = 6/3
m = 2
This piece also has slope 2. This piece is parallel to the first piece. Parallel lines have equal slopes but different y intercepts.
velocity = 2 m/s==============================================
Part (iv)
(a) The average velocity from 0 to 4 seconds is the exact same as the velocity we computed earlier in part (i). The answer is 2 m/s(b) We travel 8 meters in 6 seconds, so the average velocity is 8/6 = 4/3 = 1.33 m/s approximately. You can use the slope formula for the endpoints (0,0) and (6,8) to get the same result.(c) The average velocity is 14/9 = 1.56 m/s approximately because we travel 14 meters in 9 seconds. You can use the slope formula for the endpoints (0,0) and (9,14).As you can see, with average velocity, all we care about are the starting and ending points. We aren't concerned at all with what happens in between.
Comparing the results for part (i) and part (iv)(b), we see that the velocity has gone down. This is due to the flat portion in which you aren't moving.

The length, l, of a rectangle is 3 inches greater than its width, w. The perimeter of the rectangle is at least 30 inches. Which inequalityshows the range of possible lengths of the rectangle?
Answer:
l >= 9 and w >= 6
Step-by-step explanation:
The perimeter of the rectangle can be found by:
→ Perimeter = (2 x length) + (2 x width) (1)
Since the length is 3 inches greater than the width:
→ l = w + 3
Also, the perimeter is at least 30 inches
If you substitute the values in the equation 1:
→ (2 x l) + (2 x w) >= 30
→ (2 x (w + 3)) + (2 x w) >= 30
→ 2 x w + 6 + (2 x w) >= 30
→ 4 x w >= 24
→ w >= 6
Since l = w + 3, l >= 9

Please help it's due at 2:45!!!!!!!!
Answer:
5 (x-y)=15
2x-2y=6 and
y-x=-3
Step-by-step explanation:
first x-y=3, so you substitute x by y or y by X. anyway I substituted x by y. so x=y+3.
a. 5(x-y)
5[(y+3)-y] (first you substitute x by y+3.)
5 [y+3-y] ( then you remove the bracket.)
5[y-y+3] ( you collect like terms in the bracket.)
5 [3] (-y+y=0) so it means 5×3=15.
b. 2x-2y (like before you substitute x by y+3.)
2 (y+3)-2y
2y+6-2y (then you remove the bracket.)
2y-2y+6 (you collect like terms)
0+6=6. (because 2y-2y=0)
c. y-x
y-(y+3) ( you substitute x by y+3.)
y-y-3 (you remove the bracket)
0-3=-3 (because y-y=0)
When a higher confidence level is used to estimate a proportion and all other factors involved are held constant
Options :
A) the confidence interval will be wider.
B) the confidence interval will be narrower.
C) there is not enough information to determine the effect on the confidence interval.
D) the confidence interval will be less likely to contain the parameter being estimated.
E) the confidence interval will not be affected.
Answer: A) The confidence interval will be wider
Step-by-step explanation: In statistics, When a higher confidence interval is used to estimate a proportion with other factors being held constant, the confidence interval will be wider. Since the confidence interval is aimed at tweaking the precision of our measurement or estimation, when we adopt a higher confidence level, we are trying g to reduce our chances of being wrong and hence increasing our precision and thus widening the level of confidence in the result obtained. That said, 95% confidence interval is wider than 90%. And 99% is wder than 95%.
20 is about what percent of 52
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 52 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 52 is 100%, so we can write it down as 52=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 52=100%
2) x=20%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
52/x=100%/20%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 20% of 52
52/x=100/20
(52/x)*x=(100/20)*x - we multiply both sides of the equation by x
52=5*x - we divide both sides of the equation by (5) to get x
52/5=x
10.4=x
x=10.4
now we have:
20% of 52=10.4

A deck of playing cards has four suits, with thirteen cards in each suit consisting of the numbers 2 through 10, a jack, a queen, a king, and an ace. The four suits are hearts, diamonds, spades, and clubs. A hand of five cards will be chosen at random. Which statement is true?
Answer:
Step-by-step explanation:
Which statements are true? Check all that apply.
The total possible outcomes can be found using 52C5.
The total possible outcomes can be found using 52P5.
The probability of choosing two diamonds and three hearts is 0.089.
The probability of choosing five spades is roughly 0.05
The probability of choosing five clubs is roughly 0.0005.
Since it can be chosen in any order, we use combination and not permutation. The number of ways of choosing 5 cards from a group of 52 cards is 52C5.
The probability of choosing two diamonds and three hearts = [tex]\frac{^{13}C_2*^{13}C_3}{^{52}C_5} = 0.0086[/tex] so the third one is not true.
The probability of choosing five spades = [tex]\frac{^{13}C_5}{^{52}C_5}[/tex] ≈ 0.0005. The fourth statement is not true
The probability of choosing five clubs = [tex]\frac{^{13}C_5}{^{52}C_5}[/tex] ≈ 0.0005, the fifth one is.
So the answer is the first and fifth statement.
The probability of selecting a combination of cards is given by the ratio of
the ways of selecting the cards to the number of possible outcomes.
The true statements are;
The total number possible outcomes is ₅₂C₅.The probability of choosing five clubs is roughly 0.0005.Reasons:
First statement;
Number of cards in the deck of playing cards = 52
The number of possible outcome is given by the combinations of 5 that can be chosen from 52, as follows;
[tex]\displaystyle The \ \mathbf{number} \ of \ \mathbf{possible \ outcomes}} = _{52}C_5 = \frac{52!}{5! \cdot (52 - 5)!} = 2598960[/tex]
Therefore;
The statement; the total number possible outcomes is ₅₂C₅ is trueThird statement;
The number of ways of choosing two diamonds is found as follows;
[tex]\displaystyle Choosing \ two \ diamonds = _{13}C_2 = \mathbf{\frac{13!}{2! \cdot (13 - 2)!}} = 78[/tex]
The number of ways of choosing three hearts is found as follows;
[tex]\displaystyle Choosing \ three \ hearts = _{13}C_3 = \frac{13!}{3! \cdot (13 - 3)!} = 286[/tex]
The number of ways of choosing two diamonds and three hearts is found as follows;
[tex]\displaystyle Choosing \ two \ diamonds \ and \ three \ hearts = \frac{_{13}C_2 \times _{13}C_3}{_{52}C_5} = 0.00858[/tex]
Therefore, the number of ways of choosing two diamonds and three hearts ≠ 0.089
[tex]\displaystyle Choosing \ two \ diamonds \ and \ three \ hearts = \mathbf{\frac{_{13}C_2 \times _{13}C_3}{_{52}C_5}} \neq 0.089[/tex]
Fourth statement;
[tex]\displaystyle Probability \ of \ choosing \ five \ spades = \frac{_{13}C_5 }{_{52}C_5} \approx 0.0005[/tex]
Therefore;
[tex]\displaystyle Probability \ of \ choosing \ five \ spades = \mathbf{\frac{_{13}C_5 }{_{52}C_5}} \neq 0.05[/tex]
Fifth statement;
[tex]\displaystyle Probability \ of \ choosing \ five \ clubs= \frac{_{13}C_5 }{_{52}C_5} \approx 0.0005[/tex]
Therefore;
The statement, the probability of choosing five clubs is roughly 0.0005 is true.The possible question options in the question are;
The total possible outcomes is given by ₅₂C₅
The total possible outcomes is given by ₅₂P₅
Probability of choosing 3 hearts and 2 diamonds is 0.089

Carol is solving the inequality 3

There are infinitely many solutions.
There are only two solutions.
There is only one solution.
There are no solutions.
Answer:
There are infinitely many solutions
Step-by-step explanation:
Firstly, I need to change f to x as the system won’t accept the word f
Let’s take a look at the question;
3 is less than x
The domain of our answer lies in the the range of values where we have numbers that are greater than 3
This means we can rewrite our inequality as x is greater than 3
Now, simply because we have an infinite amount of numbers which are greater than 3 of which x can take any of the values, we can conclude that the number of values we have for x are infinite and does not end
This makes us have infinitely many solutions for the value of x

What is the length of the altitude of the equilateral triangle below?
Answer:
D 5sqrt(3)
Step-by-step explanation:
We can use the Pythagorean theorem to solve since the altitude is perpendicular to the base
a^2+b^2 = c^2
5^2 + a^2 = 10^2
25+a^2 = 100
a^2 =100-25
a^2 = 75
Taking the square root of each side
a = sqrt(75)
a = sqrt(25)sqrt(3)
a = 5sqrt(3)

A circle is cut into congruent sections and arranged to form a figure that approximates a parallelogram. Find the approximate height of the figure when its area is 12.25π square centimeters.
Answer:
The height is 3.43 centimeters, approximately.Step-by-step explanation:
Notice that there are 16 pieces from the circle, which means each sector has an angle of
[tex]\theta = \frac{360\°}{16}=22.5\°[/tex]
Where all sectors have equal area.
Now, the area of the whole circle is [tex]12.25 \pi \ cm^{2}[/tex], if we use the formula of its area, we'll find the radius of the circle
[tex]A= \pi r^{2}\\ 12.25\pi = \pi r^{2}\\ r=\sqrt{12.25} \approx 3.5[/tex]
Notice that each piece works as an isosceles triangle, because each side is the radius, that is, they have the same length. So far, we know the sides of the isosceles triangle and one internal angle.
To find the height of the one piece, we need to use trigonometric reasons, because the height divides a triangle in two equal right triangles.
[tex]cos(11.25\°)=\frac{h}{3.5}\\ h=3.5 \times cos(11.25 \°)\\h \approx 3.43[/tex]
Therefore, the height is 3.43 centimeters, approximately.

Fred's birthday party will be in a room at the community center. The room can hold 75 people. He wants to use tables that seat 5 people each. Which inequality can be used to find the maximum number of tables, t, that Fred can use?
Answer:
75>5t
Step-by-step explanation:
Here is the information given:
75 is the maximum
5 per table
t is table
So, 75 is greater than or equal to the number of tables.
If 5 is the max seated at a table we know that it will be 5 people per table or 5t
Which gives us 75>5t
Furthermore, when solving we get t=15, when plugging this in the inequality becomes 75>75 which is true.

Step-by-step explanation:
Hi, to answer this question we have to analyze the statement given and write an equation:
Sixteen is five less than a number
So, the number sixteen (16) is (=) five less (-5) than a number (n).
We have to subtract 5 to a number (x) and that expression must be equal to 16.
Mathematically speaking:
16= n-5
So, the correct option is:
Replace "is" with =, "less than" with –, and "a number" with n to get 16 = n – 5
