Answer:
x > 250
Step-by-step explanation:
we are to express the statement using an inequality expression
Since my sister plans to sell more than 250 boxes of cookies, the inequality sign to use will be a greater than sign (>), since my sister is not selling amount less. Hence the required inequality will be x > 250 where;
x is the amount of box of cookies

A test is 45 minutes long. There are 3 sections of the test that each take an equal amount of time. How many minutes m is each section of the test? Write an equation to represent the number of minutes for each section.
Please help me
Answer:
15
Step-by-step explanation:
Answer:
each section takes 15 minutes long
Step-by-step explanation:
An equation you can use to get this is 45 ÷ 3 = x

so the answer to the equation would be 45 ÷ 3 = 15
You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?
Answer:
$0.33 per cookie
Step-by-step explanation:
The unit rate (cost per cookie) is
$4
---------------- = $0.33 per cookie
12 cookies
Answer:
Roughly $0.34
Step-by-step explanation:
Set up an equation:
Variable x = cost of one cookie
12cookies/$4 = 1cookie/x
12/4 = 1/x
Cross multiply
12 × x = 4 × 1
12x = 4
Divide both sides by 12
12x ÷ 12 = 4 ÷ 12
1x = 4/12
x = 0.333333
x = is about $0.34

Answer:
<GHI = 135 degrees
Step-by-step explanation:
(3x + 12) + (x + 4) = 180
4x + 16 = 180
4x + 16 - 16 = 4x
180 - 16 = 164
4x = 164
4x / 4 = x
164 / 4 = 41
x = 41
3 * 41 + 12
3 * 41 = 123
123 + 12 = 135

What are Trigonometric Functions?Trigonometric functions are those functions which are the ratio of the sides of a right angled triangle.
Given,
sin² (x) = [1 - cos (2x)] / 2
We have to prove sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]
First, we have
sin² (x) = [1 - cos (2x)] / 2
Substituting x/2 in place of x, we get,
sin² (x/2) = [1 - cos (2x/2)] / 2
sin² (x/2) = [1 - cos (x)] / 2
sin² ([tex]\frac{x}{2}[/tex]) = [tex]{\frac{1-cos (x)}{2} }[/tex]
Taking square root on both sides,
sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]
Hence it is proved.

What is the solution set of the equation?
[tex]\sqrt{x} -18+9x=x[/tex]
9514 1404 393
Answer:
x ∈ {2.07014981016}
Step-by-step explanation:
The equation can be rewritten as ...
√x = 18-8x
x = 324 -288x +64x²
64x² -289x +324 = 0
x = (289 ±√577)/128 ≈ {2.07015, 2.44548}
Since √x must be positive, we know that ...
18 -8x ≥ 0
x ≤ 18/8 = 2.25
The larger of the above solutions is extraneous, so the solution set is ...
x ∈ {(289 -√577)/128} ≈ {2.07015}

If another sample of size 100 is taken, what is the probability that its sample mean will
be greater than 2.56 in?
Answer:
I don't know the answer to this but
Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

Answer:

Step-by-step explanation:
Use the part/whole = %/100.
You have that whole = 115 and % = 20, so that would be:
[tex]part/115=20/100[/tex]
simplify & solve:
[tex]part/115=1/5[/tex]
multiply both sides by 115
[tex]part=115/5\\part = 23[/tex]
