You cannot divide by 0
so solve
y(z+5)=0
y=0 and z+5=0
y=0 and z=-5

excluded values are y=0 and z=-5

the answer is the third option: y = 0; z = -5

The formula of this equation would be $x_{0}$ * 1.026^16 = 7,160.06
So from this equation we know that $x_{0} = \frac{7,160.06}{1.026^{16} }$
Now we need to find the value of x, we need to multiply $x_{0}$ * 1.026 16 times. Which will bring us to your answer. $4,748.53

A sample of 5 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the pop

Helen [10]

Answer:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}$

But we need to calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_I}{n}$

And replacing we got:

$\bar X = \frac{ 1.04+1.00+1.13+1.08+1.11}{5}= 1.072$

And for the sample variance we have:

$s^2 = \frac{(1.04-1.072)^2 +(1.00-1.072)^2 +(1.13-1.072)^2 +(1.08-1.072)^2 +(1.11-1.072)^2}{5-1}= 0.00277\ approx 0.003$

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance $\sigma^2$

$E(s^2) = \sigma^2$

Step-by-step explanation:

For this case we have the following data:

1.04,1.00,1.13,1.08,1.11

And in order to estimate the population variance we can use the sample variance formula:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}$

But we need to calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_I}{n}$

And replacing we got:

$\bar X = \frac{ 1.04+1.00+1.13+1.08+1.11}{5}= 1.072$

And for the sample variance we have:

$s^2 = \frac{(1.04-1.072)^2 +(1.00-1.072)^2 +(1.13-1.072)^2 +(1.08-1.072)^2 +(1.11-1.072)^2}{5-1}= 0.00277\ approx 0.003$

And thi is the best estimator for the population variance since is an unbiased estimator od the population variance $\sigma^2$

$E(s^2) = \sigma^2$

PLEASE HELP I WILL MARK YOU BRAINLIEST. Ms. Simmons is using sticky notes to write reminders to herself. Each sticky note is 5/6

Masja [62]

Answer:

5 square inches

Step-by-step explanation:

First, we need to find the area of one sticky note:

The formula is Lenth*Width

Area of one sticky note:

5/6*2/3=10/18

=5/9 square inches

Now, we find the area of 9 sticky notes:

5/9*9=5

5 square inches

Hope this helps! Have an amazing day!
