Hey there
.65 as a decimal would be <span>13/20
13 divided by 20 = 0.65
0.65 is also know as .65
hope this helps

Answer:
(d) μ and σ²/n
Step-by-step explanation:
In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.
The standard deviation of the sampling distribution of sample means is given by
σ/√n.
The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be
(σ/√n)² = σ²/(√n)² = σ²/n
Answer:
2
Step-by-step explanation:
The slope-intercept form is
y=mx+b, where m is the slope and b is the y-intercept.y=mx+bRewrite in slope-intercept form.Simplify 2(x+1).Apply the distributive property.
y+5=2x+2⋅1
multiply 2 by 1.
y+5=2x+2
y+5=2x+2
Move all terms not containing y to the right side of the equation.Subtract 5 from both sides of the equation.
y=2x+2−5
y=2x−3
the slope is the "m" so the slope is 2
Answer:D
Step-by-step explanation:
Answer:
77 nickels
106 dimes
Step-by-step explanation:
Let there be n nickes and d dimes
Since there are 183 coins, we can write:
n + d = 183
Also, the value of nickel is 0.05 and dime is 0.1, total value is 14.45, so we can write:
0.05n + 0.1d = 14.45
Solving 1st equation for n, we have:
n = 183 - d
Putting this into 2nd equation and solving for d:
There are 106 dimes
Since, n = 183 - d
n = 183 - 106
n = 77
There are 77 nickels
