Step-by-step explanation:
The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.
Given: side x = 3 cm
Use the diagonal formula,
Diagonal of cube = 3–√x
Diagonal of cube = 3–√ × 3
We know that the value of √3 is 1.734
Therefore, the diagonal of a cube = 1.734 (3)
Diagonal of cube = 5.20 cm

Use the original price and the markup to find the retail price.
Original price: $70; Markup: 15%
Answer:
$80.50
Step-by-step explanation:
To find the retail price:
Find 15% of $70. 0.15 × $70 = $10.50Add the markup price to the original price. $70 + $10.50 = $80.50Final answer - $80.50Suppose you randomly select a sample of 16 observations from a population with =11 and =2 You find ⎯⎯⎯=9. The sampling error is _____ -2 2 -1 1
Answer:
- 2
Step-by-step explanation:
Given that :
Population mean, μ = 11
Population standard deviation, σ = 2
Sample mean, xbar = 9
Sample size, n = 16
The sampling error could be explained as the variation or difference which exists in statistical measure of the population and sample as the sample data does not totally or wholly represent the population data. This difference in sample and population mean is called sampling error.
Hence, the sampling error in the above scenario can be obtained thus :
Sampling error = (xbar - μ)
Sampling error = 9 - 11 = - 2
6 is 25% of what number? (also I can confirm that this is not a test)
Answer:
24
Step-by-step explanation:
6/ x = 25%/100%
100*6 = 600
600/25 = 24
Answer:
[tex]6/24 = 25/100\\[/tex]
25% = 1/4 = 6/x
so 4*6 = 24
6 is 25% of 24.

Which number line shows that point A is 4 units from 0?
which angle is supplementary to.... asap plz
Answer:
Angle AGC
Step-by-step explanation:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary

A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for Pi and round to the nearest whole number.) A circle inside of a square with side lengths of 12 inches. The circle has a diameter of 12 inches. 31 inches squared 69 inches squared 106 inches squared 125 inches squared
Answer:
31 inches squared
Step-by-step explanation:
Area of shaded part = area of square - area of circle
area of square = length²
12² = 144
Area of a circle = πr²
r = radius = 12/2 = 6
(3.14) x 6² = 113.04
Area of shaded part = 144 - 113.04 = 30.96
rounding off to the nearest whole number gives 31
Answer:
31 squared inches

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?
Answer:
El valor de cada cuota fija es de $500.
Step-by-step explanation:
Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:
8000-6500=1500
1500/3=500
De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.

There are 8 big fish for every___
small fish.
There are 4 big fish for every___
small fish.
The image is attached any way pls someone i beg u help me.
Answer and Step-by-step explanation:
We have to use the image to help us answer this question.
We see that there are 8 big fish in the tank, and 10 small fish in the tank.
So, for the first part, it would be:
There are 8 big fish for every 10 small fish.
For when there are 4 big fish, we need to divide 10 by 2, since 8 divided by 2 is 4.
10 ÷ 2 = 5
So,
There are 4 big fish for every 5 small fish.
I hope this helps!!

The length of a rectangle is 7 cm longer than its width.
The area of the rectangle is 120 cm².
What is the width of the rectangle?
Enter your answer in the box.
Answer:
length = 15 width = 8
Area 15x8 = 120
Step-by-step explanation:
L = length
W= width
L = W + 7 (width plus7)
Area = W x L
Area =W (W+7)
Do the distribution:
120 = W ² + 7W
Subtract 120 on both sides
W + 7W -120 = 0
Factor it
(W + 15)(W - 8) = 0
W = -15 or W = 8
8 is used for W
L = W + 7
L = 8+7=15
Length = 15
Width =8.
Which function is the same as the linear
function represented by the table?
x y
-4 -14
-2 -8
0 -2
2 4
4 10
Answer:
y=3x-2
Step-by-step explanation:
We know the equation ends in -2 because when x is zero, y is -2
To find the rest of the equation take any other point and take away the -2 from y
Then divide the y by the x to see how may times larger (or smaller) the y is then the x
(I chose -14)
-12÷-4=3
y=3x
the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table

A television newscaster from a 24-hour news station wants to estimate the number of hours per day its viewers watch
programming on this channel
. The neviscaster randomly selects 100 viewers and asks them how many hours per day
they watch this station. The newscaster constructs an 85% confidence interval for the true mean number of hours
viewers watch this station. Which of the following would decrease the margin of error?
Answer:
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.
