koban [17]

Answer:

chocolate bar - 1 (whole number)

Step-by-step explanation:

$1 - \frac{1}{3} \\ > \frac{3}{3} - \frac{1}{3} = \frac{2}{3}$

$\frac{2}{3} - \frac{3}{4} \\ > \frac{2 \times 4}{3 \times 4} - \frac{3 \times 3}{4 \times 3} \\ \\ \\ > \frac{8}{12} - \frac{9}{12}$

so I switch it become

$\frac{9}{12} - \frac{8}{12} = \frac{1}{12}$

Margaret [11]

Answer:

143.31 < µ < 176.69

Step-by-step explanation:

The manager wants a 90% confidence interval based on the data. We are given 6 weekdays of data. We have to do 3 things:

1. Calculate the mean number of customers

2. Calculate the standard deviation of the number of customers

3. Construct the confidence interval

*For #1 and #2, see attached photo 1 for the calculations...

The sample mean is: 160

The sample standard deviation is: 20.29

The t-value we need is found using the t-distribution chart, with 5 degrees of freedom. Our t-value is: 2.015

*See attached photo 2 for construction of the confidence interval

Arthur ran around a circular field 3 times. If he ran a total of 750m what is diameter and radius

Dmitrij [34]

Answer:

Hope this helped

Step-by-step explanation:

Circumference = 750 m / 3

Circumference 250 m

Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters

Solving for the diameter

250 m = pi * D

D = 250 m / pi

D = 79.58 m is the diameter of the circular field

Solving for the radius

r = 1/2 D where r is the radius of the circular field

r = 39.59 m is the radius of the circular field
