Kenzie bakes 9 oatmeal cookies. Kenzie bakes 7 fewer
cookies than Lisa. How many oatmeal cookies does
Lisa bake?
Answer:
16 oatmeal cookies
Step-by-step explanation:
We can represent this situation as an equation.
L - 7 = 9 L represents Lisa's cookies, (-7) represents 7 fewer cookies, and 9 represents Kenzie's cookiesStep 1: Add 7 to both sides.
[tex]L-7+7=9+7[/tex] [tex]L=16[/tex]Therefore, Lisa baked 16 oatmeal cookies.

3+7=10
There's no exponents
You have to do it in order from left to right
6÷2=3
3*10=30
Answer:
The answer is 30.
First, start with 3 plus 7...that gives you 10. Then, 6 divided by 2 is 3. Lastly, multiply 10 by 3 and you've got 30!

1. Physicians There are about 900,000 active physicians in the United States, and they have annual incomes with a distribution that is skewed instead of being normal. Many different sam- ples of 40 physicians are randomly selected, and the mean annual income is computed for each sample.
a. What is the approximate shape of the distribution of the sample means (uniform, normal, skewed, other)?
b. What value do the sample means target? That is, what is the mean of all such sample means?
Using the Central Limit Theorem, it is found that:
a) The shape is approximately normal.
b) It targets the population mean.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
Item a:
The variable is skewed, however, the sample size is greater than 30, hence the approximate shape of the distribution is normal.
Item b:
According to the mean of the sampling distributions, given by the Central Limit Theorem, it targets the population mean.

Step-by-step explanation:
3 2/4 you have to multiply 3x4 which equals to 12 then you add 2. your answers is 14 but you need to keep the denominator 4. your final answer is 12/4. this is the improper fraction. you do the same to 4 2/5.
If a> 1 then prove that a^2>1
Step-by-step explanation:
a² = a × a
a > 1
a² = (1+d) × (1+d) = 1² + 2d + d²
with d > 0
since d > 0, then so is 2d and also d².
so, a² is the sum of 1² = 1 and something greater than 0.
so, a² > 1

Hi!
The formula for volume is length * width * height
We are given the area of the base of the figure and the height.
The volume for area is length * width
That means that the length * width part of the volume formula is already done, so we just have to multiply that by the height.
[tex]3 \frac{3}{8}[/tex] * [tex]2[/tex]
[tex]6 \frac{6}{8}[/tex] [tex]= 6\frac{3}{4}[/tex]
For other volume-related questions, see:
https://brainly.com/question/18571772
We know that:
Volume = L × B × HIf L and B are multiplied, they will find the area of the base.L × B = Area of base of rectangular prism.If L and B are multiplied, they will find the area of the base.
This means that:
Area of base of rectangular prism = L × B = 3 3/8 units²Volume = Area of base of rectangular prism × HSubstitute the area of base of rectangular prism in the volume formula.
Volume = Area of base of rectangular prism × H=> Volume = 3 3/8 × HSubstitute the height in the volume formula.
=> Volume = 3 3/8 × 2You can further solve this in two methods. You can use any of them.
Method #1:Convert the mixed fractions into improper fraction.
=> Volume = [(3 × 8 + 3)/8] × 2=> Volume = [(24 + 3)/8] × 2 [Multiplication first]=> Volume = [(27)/8] × 2=> Volume = 27/8 × 2Multiply the fractions
=> Volume = 54/8 units³ = 27/4 units³Convert the volume into mixed fraction:
27/4 = 24/4 + 3/4 = 6 + 3/4 = 6 3/4 units³Method #2:Break 3 3/8 into smaller parts:
(3 3/8) × 2=> (24/8 + 3/8) × 2Simplify the distributive property:
=> 2(3) + 2(3/8)=> 6 + 6/8 = 6 6/8 = 6 3/4 units³Likewise, you can use any method, it will give the same result.

what does X and Y represent? I've solved this equation (i got 65 and 5) what do they represent?
Answer:
Step-by-step explanation:
X would be adults Y would be children
3x+3y=35
2x+4y=25
One of the variables have to be equal to each other. So multiply all the terms in the bottom equation by 1.5
You get 3x+6y=37.5
Subtract one equation from another
3x+3y=35
3x+6y=37.5
You get 3y=2.5
Divide both sides by 3
y = 5/6
Now do the same but for X
Multiply the equation by 4/3

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A system of equations x + y = a and 2x + y = b.
Now,
x + y = a.
x = a - y and y = a - x.
2x + y = b.
2x = b - y.
x = (b - y)/2.
y = b - 2x.
An expression for x in terms of a and b is,
x + y = a
x + b - 2x = a.
- x = a - b.
x = b - a.
An expression for y in terms of a and b is,
2(a - y) + y = b.
2a - 2y + y = b.
2a - y = b.
- y = b - 2a.

Problem 4: Solve the initial value problem
[tex]y' = (y + 1)(y - 2)[/tex]
[tex]y(0) = 1[/tex]
Separate the variables:
[tex]y' = \dfrac{dy}{dx} = (y+1)(y-2) \implies \dfrac1{(y+1)(y-2)} \, dy = dx[/tex]
Separate the left side into partial fractions. We want coefficients a and b such that
[tex]\dfrac1{(y+1)(y-2)} = \dfrac a{y+1} + \dfrac b{y-2}[/tex]
[tex]\implies \dfrac1{(y+1)(y-2)} = \dfrac{a(y-2)+b(y+1)}{(y+1)(y-2)}[/tex]
[tex]\implies 1 = a(y-2)+b(y+1)[/tex]
[tex]\implies 1 = (a+b)y - 2a+b[/tex]
[tex]\implies \begin{cases}a+b=0\\-2a+b=1\end{cases} \implies a = -\dfrac13 \text{ and } b = \dfrac13[/tex]
So we have
[tex]\dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = dx[/tex]
Integrating both sides yields
[tex]\displaystyle \int \dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = \int dx[/tex]
[tex]\dfrac13 \left(\ln|y-2| - \ln|y+1|\right) = x + C[/tex]
[tex]\dfrac13 \ln\left|\dfrac{y-2}{y+1}\right| = x + C[/tex]
[tex]\ln\left|\dfrac{y-2}{y+1}\right| = 3x + C[/tex]
[tex]\dfrac{y-2}{y+1} = e^{3x + C}[/tex]
[tex]\dfrac{y-2}{y+1} = Ce^{3x}[/tex]
With the initial condition y(0) = 1, we find
[tex]\dfrac{1-2}{1+1} = Ce^{0} \implies C = -\dfrac12[/tex]
so that the particular solution is
[tex]\boxed{\dfrac{y-2}{y+1} = -\dfrac12 e^{3x}}[/tex]
It's not too hard to solve explicitly for y; notice that
[tex]\dfrac{y-2}{y+1} = \dfrac{(y+1)-3}{y+1} = 1-\dfrac3{y+1}[/tex]
Then
[tex]1 - \dfrac3{y+1} = -\dfrac12 e^{3x}[/tex]
[tex]\dfrac3{y+1} = 1 + \dfrac12 e^{3x}[/tex]
[tex]\dfrac{y+1}3 = \dfrac1{1+\frac12 e^{3x}} = \dfrac2{2+e^{3x}}[/tex]
[tex]y+1 = \dfrac6{2+e^{3x}}[/tex]
[tex]y = \dfrac6{2+e^{3x}} - 1[/tex]
[tex]\boxed{y = \dfrac{4-e^{3x}}{2+e^{3x}}}[/tex]
