Answer:
4.70
Step-by-step explanation:
there are 6 sides on a box
2 sides are 12 square feet (3*4), 2 sides are 15 square ft (3*5), and 2 sides are 20 square ft (4*5)
12*2+15*2+20*2=24+30+40=94 square feet
if each square foot costs $0.05 (I think that's what it says) then you would do 94*0.05= $4.70
so, your answer is $4.70
Not sure if this is right, but I tried
-5.225 as a mixed number.

Pamela is 14 years younger than Jiri. The sum of their age is 70. What is Jiri’s age?
Answer:
56 ...
Step-by-step explanation:
70-14 = 56
Since it’s the sum of their age it’s just jiri’s age plus Pamela’s so you just subtract Pamela’s age from the total sum. And that would make jiri 56. (Sum means the total from adding) So if you do the problem over again. “The sum of 56 and 14” it would take you back to the question you have now. This is inverse addition.
Answer:42
Step-by-step explanation: you split 70 in half, 35 and 35. Then you add 7 to one (Jiri) and subtract 7 from one(Pamela). You get 42 and 28. To check you do 42-28=14 and 42+28=70.
Which of the following is not a characteristic of the t test? Choose the correct answer below. A. The Student t distribution has the same general bell shape as the standard normal distribution. B. The Student t distribution has a mean of t=0 and a standard deviation of s=1. C. The t test is robust against a departure from normality. D.

Ryan needs 20 feet of cable. The longest piece on her truck is 18 3/8 feet. How many feet too short is the cable on the truck? *
Answer:
1 5/8 too short
Step-by-step explanation:
The cable on the truck is 18 and 3/8 ... to complete the fraction into a whole number we would need 5 more parts in order to complete the entire 8 parts of the fraction. This would make the cable a whole 19 feet. Since Ryan needs 20 ft, this would leave us needing 1 more foot. Therefore, the cable in the truck is
1 5/8 too short

Answer:
x = 15
z = 25
Step-by-step explanation:
In [tex] \odot\: O, \: \angle MLK [/tex] is inscribed in a semicircle.
[tex] \therefore m\angle MLK =90\degree [/tex]
[tex] \therefore 6x\degree =90\degree [/tex]
[tex] \therefore 6x =90[/tex]
[tex] \therefore x =\frac{90}{6}[/tex]
[tex] \therefore x =15[/tex]
In [tex] \odot\: A, \: \angle PRQ[/tex] is inscribed in a semicircle.
[tex] \therefore m\angle PRQ =90\degree [/tex]
[tex] \therefore (4z-10)\degree =90\degree [/tex]
[tex] \therefore 4z-10 =90[/tex]

The experimental probability that Diana will win a game is 3/8. If she plays the game 80 times, approximately how many times should she expect to win?
Answer:
She should win approximately 30 times.
Step-by-step explanation:
Since the probability of winning is 3/8, we multiply 3/8 with 80 to get 30.

Step-by-step explanation:
A factory received a shipment of 11 hammers, and the vendor who sold the items knows there are 2 hammers in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the hammers in the sample are defective, he will refuse the shipment. Give answer as a decimal to three decimal places
Question:
If a sample of 2 hammer is selected
(a) find the probability that all in the sample are defective.
(b) find the probability that none in the sample are defective.
Answer:
a [tex]Pr = \frac{2}{110}[/tex]
b [tex]Pr = \frac{72}{110}[/tex]
Step-by-step explanation:
Given
[tex]n = 11[/tex] --- hammers
[tex]r = 2[/tex] --- selection
This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities
Solving (a): Probability that both selection are defective.
For two selections, the probability that all are defective is:
[tex]Pr = P(D) * P(D)[/tex]
[tex]Pr = \frac{2}{11} * \frac{2-1}{11-1}[/tex]
[tex]Pr = \frac{2}{11} * \frac{1}{10}[/tex]
[tex]Pr = \frac{2}{110}[/tex]
Solving (b): Probability that none are defective.
The probability that a selection is not defective is:
[tex]P(D') = \frac{9}{11}[/tex]
For two selections, the probability that all are not defective is:
[tex]Pr = P(D') * P(D')[/tex]
[tex]Pr = \frac{9}{11} * \frac{9-1}{11-1}[/tex]
[tex]Pr = \frac{9}{11} * \frac{8}{10}[/tex]
[tex]Pr = \frac{72}{110}[/tex]

Find an equation for the inverse for each of the following.
Answer:
To solve these first swap x and y, solve for y and name it inverse function3. y = -8x + 2
x = -8y + 28y = -x + 2y = -x/8 + 2/8y = -(18)x + 1/4f⁻¹(x) = -(18)x + 1/4
-----------------------------------------
4. y = (2/3)x - 5
x = (2/3)y - 5(2/3)y = x + 5y = (3/2)x + (3/2)5y = 1.5x + 7.5f⁻¹(x) = 1.5x + 7.5
-----------------------------------------
5. f(x) = 2x² - 6
x = 2y² - 62y² = x + 6y² = 1/2x + 3y = [tex]\sqrt{1/2x + 3}[/tex]f⁻¹(x) = [tex]\sqrt{1/2x + 3}[/tex]
-----------------------------------------
6. y = (x - 3)²
x = (y - 3)²[tex]\sqrt{x}[/tex] = y - 3y = 3 + [tex]\sqrt{x}[/tex]f⁻¹(x) = 3 + [tex]\sqrt{x}[/tex]
Find the surface area of a cube with side base length 10m.
Answer:

There are 4 points that form a rectangle. Three of the points are: (-5 -1) (-5 3) (2<3 What are the coordinates of the fourth point?
Answer:
[tex]C = (2,-1)[/tex]
Step-by-step explanation:
Given
[tex]A = (-5,-1)[/tex]
[tex]B = (-5,3)[/tex]
[tex]D = (2,3)[/tex]
Required
The coordinate of the fourth point (C)
The given coordinates indicate the rectangle is vertical/horizontal because it has similar x and y values.
The coordinate of such rectangle can be represented as:
[tex]A = (x_1,y_1)[/tex]
[tex]B = (x_1,y_2)[/tex]
[tex]C = (x_2,y_1)[/tex]
[tex]D = (x_2,y_2)[/tex]
By comparing the general coordinates with the given coordinates, we have:
[tex]x_1 = -5[/tex] --- see A and B
[tex]y_1 = -1[/tex] --- see A and C
[tex]x_2 = 2[/tex] ---- see C and D
[tex]y_2 = 3[/tex] --- see B and D
So, we have:
[tex]C = (x_2,y_1)[/tex]
[tex]C = (2,-1)[/tex]

Answer:
192π ≈ 603.19 cubic units384π ≈ 1206.37 cubic unitsStep-by-step explanation:
The volume of a cylinder is given by the formula ...
V = πr²h
For the given radius and height, the volume is ...
V = π(8)²(3) = 192π ≈ 603.19 . . . . cubic units
When the height is doubled, the volume is doubled:
V = π(8)²(6) = 384π ≈ 1206.37 . . . . cubic units

C)The hydrophilic heads point into and out of the cell, while the hydrophobic tails form a layer between the heads.
D)The hydrophilic tails point into and out of the cell, while the hydrophobic heads form a layer between the tails.
Fast plz.
Answer:
Option D
Step-by-step explanation:
The phospholipid bilayer that makes up a cell membrane comprises of two essential parts a) Water loving part or the hydrophilic part which points outwards towards cytoplasm and b) Water hating part of hydrophobic part which point towards the interior of the membrane, and is sandwiched between two layers of hydrophilic heads

insert 7 arithmetic means between 4 and 8
Answer:
mafi mallum
Step-by-step explanation:
The 7 arithmetic means between 4 and 8 are
9/2, 5, 11/2, 6, 13/2, 7, and 15/2.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
First term = 4
This means,
a = 4
9th term = 8
This means,
a + (9 - 1)d = 8
4 + 8d = 8
8d = 8 - 4
8d = 4
d = 4/8
d = 1/2
Now,
2nd term = 4 + (2 - 1)1/2 = 4 + 1/2 = 9/2
3rd term = 4 + 2 x 1/2 = 4 + 1 = 5
4th term = 4 + 3 x 1/2 = 11/2
5th term = 4 + 4 x 1/2 = 4 + 2 = 6
6th term = 4 + 5 x 1/2 = 13/2
7th term = 4 + 6 x 1/2 = 4 + 3 = 7
8th term = 4 + 7 x 1/2 = 15/2
Thus,
The arithmetic sequence is 4, 9/2, 5, 11/2, 6, 13/2, 7, 15/2, 8.
