Cory has a rectangular piece of cardboard that measures 36 inches 24 inches. He cuts out squares of 4 inches from each corner of the cardboard. Then he folds and tapes the sides together to make an open box 36 inches 24 inches What is the volume of the open box?
Answer:
1792 cubic inches
Step-by-step explanation:
The rectangular cardboard measures 36 inches by 24 inches.
If he cuts out squares of 4 inches from each corner of the cardboard.
See the attached image
The Length of the box =36-4-4=28 inches
The Width of the box =24-4-4=16 inches
Height of the Box =4 Inches
Therefore:
Volume of the open box =28 X 16 X 4
=1792 cubic inches

A random sample of n1 = 16 communities in western Kansas gave the following information for people under 25 years of age.
x1: Rate of hay fever per 1000 population for people under 25
144 89 119 119 125 136 91 109 111 108 116 123 120 121 115 123
A random sample of n2 = 14 regions in western Kansas gave the following information for people over 50 years old.
x2: Rate of hay fever per 1000 population for people over 50
109 109 90 81 85 94 92 106 110 89 87 94 100 90
Assume that the hay fever rate in each age group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use α =0.05. If , will you reject or fail to reject the null hypothesis? Are the data statistically significant at confidence level α?
a
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis.
b
Since the P-value is greater than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.
c
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis.
d
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we fail to reject the null hypothesis.
e
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.

2a+3/2 - a-2/3 = a-1/4
Answer:
No solutions
Step-by-step explanation:
[tex]2a+\dfrac{3}{2}-a-\dfrac{2}{3}=a-\dfrac{1}{4}\\a+\dfrac{5}{9}=a-\dfrac{1}{4}\\\dfrac{5}{9}=\dfrac{1}{4}[/tex]
This equation has no solutions. Hope this helps!
Answer:
No solution
Step-by-step explanation:
2a+3/2 - a-2/3 = a-1/4.
2a- a +3/2 - 2/3 = a-1/4. Add like terms
a + 5/6 = a - 1/4. Variables and numbers on diferent sides
-a. -5/6. -a. -5/6
0 = -13/12
No solution because there are no a's that can make the equation true

If Sue worked 7 1/4 hours on Monday, 3 hours on Tuesday, 6 3/4 hours on Wednesday, 8 hours on Thursday, and 5 hours on Friday, calculate her weekly wage at $4.10 per hour
Answer:
$123
Step-by-step explanation:
Let's find the total amount of hours Sue worked. To do so, we'll do 7.25 + 3 + 6.75 + 8 + 5 = 30 total hours. Now, we'll multiply 4.1 by 30 because she receives $4.10 for every hour. 4.1 * 30 = $123. Hope this helps!

Andrea bought 12 bagels and 10 muffins at the bakery. of these items 2/3 of the bagels were multigrain and 3/5 of the muffins were bran muffins. How many multigrain bagels did Andrea buy and how many bran muffins did Andrea buy
Answer:
She bought 8 multigrain bagels and 6 bran muffins
Step-by-step explanation:
If it says of, then it means multiply.
So it is 2/3 of 12 bagels, which is 2/3 x 12 which is 8
If it says 3/5 of 10 muffins, it is 3/5 x 10 which is 6.

help plz help plz help plz help plz
Answer:
Step-by-step explanation:
21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.
22. Again, the angles are supplementary which means that 61° + b = 180° → b = 119°.
23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.
24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°
Hope this helps!

The volume formula for a right pyramid is V=
= Bh. What does Brepresent?
O A. Area of the base
B. Perimeter of the base
C. Length of the base
O D. Volume of the base
Answer:
A.Area of the base
Step-by-step explanation:
these is obtained by multiplying the length and width of the base to get the area of the base
The variable B in the Formula is area of Base.
What is Volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Pyramid volumes are measured by how much space they take up or by how many unit cubes can fit inside of them. A pyramid is a polyhedron because it has polygonal faces.
As, Volume of pyramid = (1/3) (Bh), where
B = Area of the base of the pyramid
h = Height of the pyramid.
So, B in the Formula is area of Base.

what is the value of y?
A. 40°
B. 30°
C. 120°
D. 60°
Answer
60
Step-by-step explanation:
A triangle is 180 degrees. So first since you have one of the degrees you will do 180-60=120. Since the 2 ys are the same you can just divide 120 by 2. Which is 60. So y=60
Answer:
D - 60° because all the angles in a triangle add up to 180°

Which expressions are equivalent to k^{^{\scriptsize -\dfrac{1}{6}}}k − 6 1 k, start superscript, start superscript, minus, start fraction, 1, divided by, 6, end fraction, end superscript, end superscript ? Choose all answers that apply: Choose all answers that apply: (Choice A) A \sqrt[6]{k^{-1}} 6 k −1 root, start index, 6, end index (Choice B, Checked) B \dfrac{1}{k^6} k 6 1 start fraction, 1, divided by, k, start superscript, 6, end superscript, end fraction (Choice C) C \left(k^{-1}\right)^{^{\scriptsize\dfrac{1}{6}}}(k −1 ) 6 1 left parenthesis, k, start superscript, minus, 1, end superscript, right parenthesis, start superscript, start superscript, start fraction, 1, divided by, 6, end fraction, end superscript, end superscript (Choice D) D
Options
[tex]A)\sqrt[6]{k^{-1}}\\(B)\dfrac{1}{k^6}\\(C)\left(k^{-1}\right)^{^{\scriptsize\dfrac{1}{6}}}\\[/tex]
Answer:
[tex](A)\sqrt[6]{k^{-1}}\\(C)\left(k^{-1}\right)^{{1/6}}[/tex]
Step-by-step explanation:
Given the expression [tex]k^{^{-\dfrac{1}{6}}}[/tex] , we apply the following rule of indices to obtain equivalent forms.
Negative Exponent Rule: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]Fractional Exponent Rule: [tex]a^{1/m}=\sqrt[m]{a}[/tex]Therefore:
[tex]k^{-1/6}=(k^{-1})^{1/6}[/tex]
This is Option C,
If we simplify further, we obtain:
[tex]k^{-1/6}=(k^{-1})^{1/6}\\=\sqrt[6]{k^{-1}}[/tex]
This is option A.
Therefore, Options A and C are equivalent to the given expression.
A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount?
Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
