<span>Equivalent fractions are numbers with the same value for a number.
Multiply the numerator as well as the denominator by the same number. Therefore its like multiplying by 1.
45/60
3/4 = 9/12
<u>45 </u>x <u>15
</u>60 15 = 3/4
<u>45</u> x <u>5
</u>60 5 = 9/12

The answer is going to be exponents, I think. Not to sure though.
Hope this help! :)
Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat
The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721
Hi there! :)
Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
Plug in values from the table:
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
