Answer:
a) 12/91
b) about 67 times; (66 2/3)
Step-by-step explanation:
a) total of frequencies is 90 and frequency for a 3 is 11
however, the question said if the dice is rolled once more, then that raises the 11 to 12 and the frequency total from 90 to 91
let 'x' = # of sixes rolled out of 500 times
b) 12/90 = x/500
cross-multiply:
90x = 6000
x = 66 2/3

Answers
Answer:
$36.38
Step-by-step explanation:
If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Given data
Tax= 7%
Cost = $34
Let us solve for the amount of tax
=7/100*34
=0.07*34
=2.38
Hence the total is =2.38+34
=$36.38

Answers
Answer:
side= 6400/4
=1600
therefore the area= 1600*1600
2560000
cost of reaping 100sq.m.=35

How do you solve 2x=10
Answers
Divide both sides by 2 so x=5 (Because 10 divided by 2 is 5 and 2x turns into just x)
Hello!!
So when we have 2x = 10 we are looking for what x equals. This means you'll want to eliminate what you can to get your answer. What you do on one side must be done on the other. Let's give that a go, sha'll we?
2x = 10
We need to use the inverse operation to eliminate a factor. Since 2x is 2 times x we'll have to divide it.
2x/2 = 10
2 divided by 2 cancels each other out and leaves us with the following;
x = 10
So, x = 10

Answers
Answer:
x = 25
Step-by-step explanation:
Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is
4x - 30 = 2x + 20 ( subtract 2x from both sides )
2x - 30 = 20 ( add 30 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
Step-by-step explanation:
x=11

x - 2 = -8
Add 2 to both sides to isolate the variable, x.
x - 2 + 2 = -8 + 2
-2+2 = 0
-8+2 = -6
Therefore,
x = -6

Brent wants to solve this system of equations using subtraction 4X minus 5Y equals 11 and 8X minus 5Y equals 27 list the steps he should follow to solve the equations what is the solution
Answers
Answer:
Solution is x=4 and y=1.
Step-by-step explanation:
We are given with 4 x-5 y=11
And 8 x - 5 y =27
Let's solve them using elimination method.
Subtract the equations to get rid the 'y' terms. Or, multiply the second equation and add them together.
4 x -5 y =11
-8 x+5 y =-27
----------------------
-4x =-16
Divide both sides by -4.
x =4.
Now, plug in x as 4 into any of the given equations to find the corresponding y.
4(4) -5 y =11
16 -5 y =11
Subtract both sides 16.
-5y =-5
Divide both sides by -5
y=1

A certain hydraulic system operates at 6,000 PSI. Complete the percentage change in the volume of oil in the system as the pressure is increased from zero to 6,000 PSI if the oil has a Bulk Modulus of 186,000 PSI.
Answers
Answer:
the percentage change in the volume of the oil is -3.22%
Step-by-step explanation:
The computation of the percentage change in the volume of the oil is given below:
= -(6,000 - 0) ÷ (186,000)
= -3.22%
This negative sign represents the decrease in the volume
Hence, the percentage change in the volume of the oil is -3.22%
rewrite sin^4x that involves only the first power of cos
Answers
Answer:
We want to rewrite:
sin^4(x)
in a way that only involves the first power of the cosine function.
We know that:
sin^2(x) = 1 - cos^2(x)
Then:
sin^4(x) = sin^2(x)*sin^2(x) = sin^2(x)*(1 - cos^2(x))
Now we know that:
cos(2x) = cos^2(x) - sin^2(x)
then
cos(2x) + sin^2(x) = cos^2(x)
We can replace that in our equation to get:
sin^2(x)*(1 - cos^2(x)) = sin^2(x)*(1 - cos(2x) - sin^2(x) )
sin^2(x)*(1 - cos(2x) - sin^2(x) ) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)
then:
sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)
sin^4(x) + sin^4(x) = sin^2(x) - sin^2(x)*cos(2x)
2*sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) = sin^2(x)*(1 - cos(2x))
sin^4(x) = sin^2(x)*(1 - cos(2x))/2
So we rewrite the equation in such a way that we only have the first power of the cosine function.
