A baker uses 4 cups of flour for each cake. He has 213 cups of flour in his shop. How many cakes can he make, and how much flour
lora16 [44]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Just divide the values:

213 / 4 = 53.25

He can make 53 cakes.

53 x 4 = 212

Subtract this from the original:

213 - 212 = 1

1 cup of flour is left over

The weights of 67 randomly selected axles were found to have a variance of 3.85. Construct the 80% confidence interval for the p
VLD [36.1K]

Answer:

3.13

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 67

Variance = 3.85

We have to find 80% confidence interval for the population variance of the weights.

Degree of freedom = 67 - 1 = 66

Level of significance = 0.2

Chi square critical value for lower tail =

\chi^2_{1-\frac{\alpha}{2}}= 51.770

Chi square critical value for upper tail =

\chi^2_{\frac{\alpha}{2}}= 81.085

80% confidence interval:

\dfrac{(n-1)S^2}{\chi^2_{\frac{\alpha}{2}}} < \sigma^2 < \dfrac{(n-1)S^2}{\chi^2_{1-\frac{\alpha}{2}}}

Putting values, we get,

=\dfrac{(67-1)3.85}{81.085} < \sigma^2 < \dfrac{(67-1)3.85}{51.770}\\\\=3.13

Thus, (3.13,4.91) is the required 80% confidence interval for the population variance of the weights.

Answer: $60.00


Step-by-step explanation: First the solution: (Start form the end!!) $40.00 (the ending total) minus the $10.00 he added on, $40-$10=$30 which is half of the original total so now you have to multiply by two to get the starting balance ($60.00)!

Now for the inequality, since we don't know the beginning balance of the gift card that will be our variable.

g

Then, since he spent half of this buying coffee we would have to split our variable in half.

g/2

After that, Peter added an additional $10.00 to said  gift card.

g/2 + 10 = 40

Going off of that the final inequality would be $60.00 = g/2 + 10 = 40


BAMM!! GOOD LUCK IN MATH CLASS!!!
