A cookie jar contains four oatmeal raisin, one sugar, nine chocolate chip, and six peanut butter cookies. If one is chosen at random, find the P
Answer:
chocolate chips
Step-by-step explanation:
The p denotes here the probability which is given below;
Given that
There is 4 oatmeal raisin
1 sugar
9 chocolate chips
And, 6 peanut butter cookies
So based on the above information, the probability when the one is chosen would be of chocolate chips as it contains the hight value in the cookie jar
So the same is to be selected

Which of the following is the inverse of F(x) = 2x + 3 ?
Explanation:
y=f(x)
y=2x+3
Switch the places of x and y:
x=2y+3
Solve for y:
2y=x−3
y=(x−3)/2
Thus inverse of f(x)= (x-3)/2

8 + 36 × 2
8+72
80
Answer:
80
Step-by-step explanation:
If you use PEMDAS you'll know to do parentheses first
6^2 is 6 times 6 which is 36
then you multiply 36 by 2
72
then add 8

solve the inequality 3x+3>48
[tex]3x + 3 > 48[/tex]
Solving the Inequality is similar to solving the equation. We simply make x-term as the subject since we are solving for x.[tex]3x > 48 - 3 \\ 3x > 45 \\ x > \frac{45}{3} \Longrightarrow x > \frac{ \cancel{45}}{ \cancel{3}} \Longrightarrow x > \frac{15}{1} \\ x > 15[/tex]
Answer CheckBecause x must be greater than 15. We will substitute x = 16 in the Inequality.
[tex]3(16) + 3 > 48 \\ 48 + 3 > 48 \\ 51 > 48 \: \: \checkmark[/tex]
The Inequality is true when x > 15.

Answer:
YesNoStep-by-step explanation:
The first table represents a linear function because:
For each increase in x by 5 points we have increase in y by 10 pointsThe second table is not linear as:
For the first two steps of x by 4 points we have increase of y by 8 points but for the rest of the steps it is 6 for each 4, therefore not linearA marine biologist monitors the population of sunfish in a small lake. He records 800 sunfish in his first year, 600 sunfish in his fourth year, 450 sunfish in his sixth year, and 350 sunfish in his tenth year. Using the exponential regression equation (rounded to the hundredths),
1. Predict when the population of sunfish in the lake will be 200.
2. Predict the number of sunfish in the lake in the 25 thyear.
Answer:
Let's use the variable y to represent the number of years passed since the first year.
The population on the first year (y = 0) was 800
The population in the second year (y = 1) was 600.
The ratio in which the population decreased can be calculated as:
R = 600/800 = 0.75
This means that 600 is the 75% of 800, this also means that between the first year and the second year, the population decreased by the 25%
Now let's look at the ratio between the second and third year (y = 2), the population the third year was 450
Now the ratio is:
R = 450/600 = 0.75
Same as before, then we already can see that the population will decrease by 25% each year.
The generic exponential decay equation is:
f(y) = A*(1 - r)^y
where:
A = initial population, in this case, is 800
y = our variable, in this case, represents the number of years
r = the amount that decreases per each unit of our variable, this must be written in decimal form. In this case, we know that the population decreases by 25% each year, and 25% written in decimal form is 0.25
Also, (1 - r) = R, where R is the ratio we found earlier.
To do this, we just divide 25% by 100% to get (25%/100% = 0.25)
Then our equation will be:
f(y) = 800*(1 - 0.25)^y
f(y) = 800*( 0.75)^y
1) We want to predict when the population will be 200.
to do this, we set:
f(y) = 200 = 800*( 0.75)^y
and solve it for y.
(200/800) = 0.75^y
(1/4) = 0.75^y
Now we can use the relationship:
Ln(a^x) = x*ln(a)
Then let's apply Ln( ) in both sides to get
ln(1/4) = y*ln(0.75)
ln(1/4)/ln(0.75) = y = 4.8 years.
This means that 4.8 years after the first year, the population will be around 200.
2) The population in the 25 th year (this is 24 years after the first one, so we take y = 24) is:
f(24) = 800*(0.75)^(24) = 0.80
Around this point, we will have no more sunfish in the lake.

Erin and her friends are taking a road trip. She has agreed to drive between hours 3 and 6 of the trip. If h represents the hours of the trip Erin will be driving, then h ≥ 3 and h≤ 6 represents her portion of the driving. While she is driving, her distance and time are modeled by the inequality d < 70h. What are the possible hours and distances Erin could be driving?
When graphing this scenario, let h be the horizontal variable and d be the vertical variable.
For the inequality h ≥ 3, the graph should be shaded
the boundary line.
For the inequality h ≤ 6, the graph should be shaded
the boundary line.
For the inequality d < 70h, the graph should be shaded

if 0.4 < x > 45%, which of the following could be the value of x?
Answer:
0.41, 0.42, 0.43, 0.44
Step-by-step explanation:
Convert the percent to a decimal:
0.4 < x > 0.45
Now, the variable x has to be any number between 0.4 and 0.45, which include:
0.41, 0.42, 0.43, 0.44
Answer:
5/10
Step-by-step explanation:
So you can split this into two inequalities, x > 0.4 and x > 45%. First you can change the second one to decimal form, so x > 0.45. Because 0.45 is already greater than 0.4, you can just ignore the second inequality. (If x is greater than 0.45 it will automatically be greater than 0.4 so it doesn't matter).
From the 4 options you gave, 5/10, or 0.5, is the only one that is greater than 0.45.

Find the surface area
7 cm
6 cm
12 cm
4 cm
A)210 cm^2
B)220 cm^2
C)230 cm^2
D)240 cm^2
Answer:
The surface area is 240 cm^2
Step-by-step explanation:
The surface area is the sum of all the areas of the shapes present
we have two rectangles of measure 7 cm by 12 cm
A base rectangle of 4 cm by 12 cm
Two side triangles of base 4 cm and height 6 cm
Area of the rectangles is l * b
Area of the triangles is 1/2 * b * h
Thus, we have that;
(7 * 12) * 2 ) + 2 * (1/2 * 4 * 6) + (4 * 12)
= 168 + 24 + 48 = 240 cm^2
