Answer:
$3.77
Step-by-step explanation:
The formula for the percentage of an amount is : 
To work out the value of the tax you would first need to convert the percentage of 6.5 into a decimal. You can do this by dividing the percentage of 6.5 by 100, this gives you 0.065. This is because percentages are out of 100.
The next step is to multiply 0.065 by the amount of $58, this gives you 3.77. This is because we are working out 6.5% of $58 and so would multiply the decimal by the amount to work that out.
1) Divide 6.5 by 100.

2) Multiply 0.65 by 58.

Answer:
y + 4 = -³/₅(x + 5) {the point-slope form of the equation
}
y = -³/₅x - 7 {the slope-intercept form of the equation}
3x + 5y = - 35 {standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is : y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through.
m = -³/₅
(-5, -4) ⇒ x₀ = -5, y₀ = -4
Therefore:
y - (-4) = -³/₅(x - (-5))
y + 4 = -³/₅(x + 5) ← the point-slope form of the equation
y + 4 = -³/₅x - 3 {subtract 4 from both sides}
y = -³/₅x - 7 ← the slope-intercept form of the equation
³/₅x + y = - 7 {multiply both sides by 5}
3x + 5y = - 35 ← standard form of the equation
Answer:
490 km
Step-by-step explanation:
350 km in 5 h
350 ÷ 5 = 70 km in an hour
70 × 7 = 490 km in 7 hours
Answer:
The standard error of the mean is 10.11 points
Step-by-step explanation:
Standard error of mean = t×sd/√n
sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501
Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)
The correct answer to this question is letter "A. complex." A number written in the form a + bi is called a complex number. The "i" part is the imaginary part of that expression, which is complex. Imaginary numbers are complex and it's hard to evaluate, sometimes.
