The total cost of the book would be:

12.50* 0.8= 10

The total cost of the book would be $10.00

If the book is $12.50 with tax of 8%, the total cost of the book will be the sum of the 2 numbers.

8% of 12.50 is
.08 × 12.50 = 1.00

add 12.50 + 1.00 for a total cost of

$13.50

Answer:

The table is attached!

Step-by-step explanation:

6 students play both musical instrument and a sport
3 students play neither a musical instrument nor a sport
14 students in total play a sport

Given: There are 24 students in the class

The number of students that does not play a sport is 24 - 14 = 10

The number of students that does not play a musical instrument but play a sport = 14 - 6 = 8

The frequency table thus is attached below:

Find the arc length of the partial circle. <br>length is 1.<br>**See attached photo**<br>

KatRina [158]

Arc length of the quarter circle is 1.57 units.

Solution:

Radius of the quarter circle = 1

Center angle (θ) = 90°

To find the arc length of the quarter circle:

$$\text{Arc length}=2 \pi r\left(\frac{\theta}{360^\circ}\right)$

$$=2 \times 3.14 \times 1\left(\frac{90^\circ}{360^\circ}\right)$

$$=2 \times 3.14 \times 1\left(\frac{1}{4}\right)$

Arc length = 1.57 units

Arc length of the quarter circle is 1.57 units.

According to a survey conducted by Deloitte in 2017, 0.4702 of U.S. smartphone owners have made an effort to limit their phone u

musickatia [10]

Answer: 0.628

Step-by-step explanation:

Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702

Sample size : n= 54

Mean : $\mu =(54)(0.4702)=25.39$

Standard deviation:

$\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039$

The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :

$P(22\leq x\leq29)=P(21$

Hence, the required probability = 0.628
